Description

Detailed description of the invention

The present invention relates to a biochar production system for producing biochar by carbonizing organic biomass raw materials, a biochar production method, and a control program therefor.

In recent years, electricity produced by renewable energy has attracted attention. This electricity is produced using renewable energy resources such as sunlight, solar heat, wind, biomass, geothermal, hydropower, and atmospheric heat. Compared to power generation using fossil fuels such as oil, coal, and liquefied natural gas, power generation using renewable energy emits almost no CO2, which is a cause of global warming. , Renewable energy is an environmentally friendly energy resource. On the other hand, plastic products are used in every corner of our lives, and there are concerns that the so-called microplastics generated from discarded plastics not only pollute the environment but also have a negative impact on the health of those who consume them through seafood. Preventing the negative effects of the generated plastic waste has become an urgent issue.

In this regard, the technology for extracting hydrogen gas from biomass is well known, and the method of producing fuel with a high carbon atomic ratio by reforming cellulosic biomass such as wood and plants is also well known. It requires large-scale equipment and is difficult to use in developing countries. For this reason, biomass resources are not fully utilized, especially in developing countries such as Southeast Asia, which are rich in biomass resources. On the other hand, urban areas in developing countries often dispose of large amounts of garbage using methods that are not environmentally friendly. This is because high-performance exhaust purification devices used in developed countries are expensive, and it cannot be denied that it is difficult to introduce them in developing countries.

Patent Document 1 discloses a method for extracting at least hydrogen gas or liquid fuel from a compound containing carbon, oxygen, and hydrogen, in which water is combined with the compound to produce a wet form of the compound, and then the wet form of the compound is extracted. is moved into a reaction processing chamber, and the wet form of the compound is heated to a temperature of 700° C. to 1100° C. in the reaction processing chamber so that the wet form of the compound dissociates and reacts by a hydrothermal decomposition reaction. It is.
However, although this method can efficiently extract hydrogen gas or liquid fuel, it is necessary to continue heating the reaction chamber throughout this production process, which requires fuel or electricity. There are still issues in terms of environmental impacts such as emissions.

Patent Document 2 discloses a biomass modification that uses cellulosic biomass as a raw material to provide a modified biomass that can be made into a highly concentrated biomass water slurry with a low oxygen/carbon atomic ratio (high carbon atomic ratio) that can be used as a heavy oil alternative fuel. quality methods are disclosed. This biomass modification method involves adding 5 to 15 times the mass ratio of water to the cellulosic biomass raw material and reforming it at 250 to 380°C and at a pressure approximately 1 to 3 MPa higher than the saturated vapor pressure of water. After the treatment and the reforming step, a solid component and a liquid component mainly composed of water are separated in a separation step, and when the solid component is dried and used as a fuel, it is further heated and dried.
However, this reforming method requires a reforming process, a separation process, and a drying process, resulting in large-scale equipment and high costs.

In consideration of the above social background, the present invention provides a system for producing biochar using biomass resources as a raw material using a method that has low raw material costs, low equipment introduction costs, low running costs, and is relatively environmentally friendly. It solves the problem of providing

In this regard, for example, a person skilled in the art would be able to combine the technology of Patent Document 1 and the technology of Patent Document 2, burn the hydrogen gas produced by the technology of Patent Document 1, and utilize the heat of Patent Document 2. It may seem easy to modify biomass raw materials. However, it is clear that it is difficult to solve the problem simply by combining the two for the following reasons.

First, a heat source is required to generate hydrogen gas. Although Patent Document 1 does not have a specific description of the heating source, other documents in this field, for example, Japanese Patent Application Publication No. 2019-522067, mention in the second half of paragraph 0013 that, for example, an organic Rankine cycle using carbonized gas as a raw material Disclosed are a method in which the electrical energy obtained by a reciprocating engine is used as a heating source, and a method in which electrical energy obtained by generating electricity using the driving force obtained by a reciprocating engine is used as a heating source. However, this method increases the equipment cost and running cost for generating hydrogen gas.

Secondly, the components of the organic compounds in Patent Document 1 (e.g., a mixture of paper, plastic, plants, etc. discharged in cities) and Patent Document 2 are not uniform, and these two are used as inputs for biochar production systems. If different types of substances are used as raw materials (hydrogen generating material and raw material for biochar), it will be difficult to produce homogeneous biochar, and if you try to produce homogeneous biochar, system control will be complicated and equipment costs However, running costs will also increase.

The outline of the biochar production system of the present invention will be explained below using FIG. 1. FIG. 1 is an overall diagram of the biochar production system. In addition, the blower 40 and its piping and valves shown in FIG. 3, the storage chamber 34 and its piping and valves, the pressure gauge A60 and the suction pump 56, the air tank 48 and its piping and valves, the pressure gauge B61 and the air suction pump 58 and the communication line 55 are omitted in FIG. Each valve and each electromagnetic valve described below are each equipped with a similar actuator and a power source for driving the actuator, and each actuator is connected to the control device 32 via a communication line 55 (not shown in FIG. 1). Each valve receives a control signal, and each valve passes the target gas or liquid, and each solenoid valve passes, inhales, or discharges the target gas, liquid, semisolid, or solid. An actuator is attached to each electromagnetic valve, and each actuator receives a control signal from the control device 32 via a communication line 55, and operates in accordance with the control signal. The organic waste 1 to be inputted on the left side of FIG. The organic waste 1 inputted by the apparatus A63 and shredded is conveyed by the conveyor 3 from the discharge port of the shredder 2 and inputted into the pyrolysis furnace A4. At the end of a series of shredder processes, the shredder 2 transmits the weight of the shredded organic waste 1, the end time, and device identification information to the control device 32 as control history information. An ignition device 5 is connected to the pyrolysis furnace A4, and a blower 40 for combustion control is separately provided via a connecting pipe 54. The ignition device 5 includes a heavy oil tank (not shown) capable of storing about 2 liters of heavy oil, a control signal receiving section from the outside, a power supply, and ignition/extinguishing and firepower adjustment using the signals received by the receiving section. It is equipped with a burner that can burn for about 30 minutes, and a heat-resistant hose that connects the burner to the heavy oil tank, making it possible to burn for about 30 minutes, depending on the firepower. The ignition device 5 is connected to the control device 32 via a communication line. The communication line 55 is a wireless communication line, but may be a wired LAN cable or a two-core twisted wire (twisted pair cable). In the case of a wireless communication line, a wireless communication adapter including a power source is attached to each sensor, each valve, and each electromagnetic valve, and a wireless communication adapter is also attached to the control device 32. Further, in the case of a LAN cable, a LAN adapter including a power source is attached to each sensor, each valve, and each solenoid valve, and a LAN adapter is attached to the control device 32. In the case of a twisted pair cable, a level conversion circuit and a power supply are attached as necessary depending on the cable length, and a line concentrator is attached to the control device 32. The power source for the ignition device 5 is, for example, four single batteries (1.5 V) connected in series and two connected in parallel, but a constant voltage power source connected to a normal AC 100 V commercial power source may be used.

Part of the shredded organic waste 1 starts to burn due to the thermal power of the igniter 5, but at the initial stage, soot from the heavy oil in the igniter 5 is produced, so at this point the high-temperature gas generated by combustion in the pyrolysis furnace A4 is not introduced into the heat exchange furnace B12, and at this point, the solenoid valve B25 is open, and the high-temperature gas passes directly through the pipe C43 to the cyclone 27, which is a centrifugal dust collector, the flue gas desulfurization device 28, and the wet cleaning tower. After passing through a wet scrubber 29 that filters gas containing pollutants and a dry scrubber 30 that adsorbs pollutants to an adsorbent filter such as activated carbon, the gas is purified and then discharged into the environment through a chimney 31. On the other hand, the hydrogen-containing gas generated in the previous processing cycle stored in the storage chamber 34 shown in FIG. This contributes to stabilizing initial combustion and reducing heavy oil consumption of the ignition device 5.

When the shredded organic waste 1 in the pyrolysis furnace A4 is pyrolyzed and gasified and begins to burn stably, the ignition device 5 is extinguished, and the pyrolysis reaction is continued and burned to generate high-temperature gas. ,, When the solenoid valve B25 is closed and the solenoid valves A24 and C26 are opened substantially simultaneously, the generated high-temperature gas of 1000°C to 1200°C is introduced into the heat exchanger 6 from the piping A41 and is fed into the pyrolysis furnace B12. The temperature inside begins to rise and rises to 350°C to 450°C.
As shown in FIG. 1, the heat exchanger 6 is configured to enter the pyrolysis furnace B12 in a U-shape and transfer the heat of the high-temperature gas after combustion discharged from the pyrolysis furnace A into the pyrolysis furnace B12. has been done.

On the other hand, the biomass resources 8 to be processed are inputted into the shredder drying device 11, shredded and dried, and then conveyed by the conveyor 9. The cut and dried biomass resource 8 is put into a pyrolysis furnace B12. The shredder drying device 11 transmits the weight of the biomass resource 8 after drying, the end time, and the device identification information to the control device 32 as control history information at the end of one drying process. Nitrogen produced by the nitrogen production device 22 is input into the pyrolysis furnace B12 through the nitrogen input valve 23, and the inside of the pyrolysis furnace B12 changes from a low oxygen state to a substantially anoxic state, and the biomass resources 8 that have been input are removed. In addition to mainly H ₂ , gas containing hydrocarbons such as CH ₄ and C ₂ H ₆ , CO, etc. are generated, and the organic matter in the biomass resource 8 is decomposed, so the remaining solid or semi-solid is The carbon content gradually increases. The combustion in the pyrolysis furnace A4 is stabilized, the temperature in the heat exchange furnace B12 rises due to the heat passed through the heat exchanger 6, and the hydrogen-containing gas is opened by the hydrogen-containing gas control valve 35, which will be described later in the explanation of FIG. After that, it is sucked by the suction pump 56 and stored in the storage chamber 34 through the pipe D44. As described above, this hydrogen-containing gas assists in the combustion of the organic waste 1 in the pyrolysis furnace A4. A thermocouple type temperature sensor A33 made of a platinum-rhodium alloy for high temperatures is attached to the center of the pyrolysis furnace B12, and the voltage measured by the sensor A33 is sent to the control device via the communication line 55, and the temperature is determined within the control device 32. It is converted to . The control device 32 uses this temperature to control the opening/closing of each valve, the flow rate, the opening/closing of each solenoid valve, the on/off and rotation speed of each pump. Details of the control device 32 will be explained with reference to FIGS. 2 and 4.

After the biomass resource 8 is sufficiently carbonized to become biochar, the electromagnetic valve E13 is opened, and the purified biochar falls into the cooling device 16 by gravity. The cooling device 16 includes a solenoid valve F17 for discharging biochar, has a temperature sensor B36 attached therein, and is connected to the control device 32 via a communication line 55. When the temperature sensor B36 detects the temperature (more precisely, the voltage value corresponding to the temperature), the control device 32 sends a control signal to open the discharge solenoid valve F17 to the actuator of the solenoid valve F17 via the communication line 55. The electromagnetic valve F17 is opened, and the produced biochar can be carried out. Carrying out is performed manually or by an unillustrated carrying out device that is connected to the control device 32 via the communication line 55 and can be carried out in response to a control signal from the control device 32. Note that the control device 32 described in FIG. 2, and the blower 40 and direct air flow valve 47 described in FIG. 3 are omitted in FIG. Furthermore, a temperature sensor C37 for measuring the environmental temperature and a humidity sensor 53 for measuring the environmental humidity are attached to the outside of the nitrogen production machine 22, and each is connected to the control device 32 via a communication line 55. and transmit information to determine temperature and humidity.

FIG. 6 is a diagram showing a flowchart of pyrolysis treatment of organic waste 1 to produce high-temperature gas that becomes a heat source for pyrolysis of biochar. The pyrolysis process is part of the control program of the biochar manufacturing system, and is stored in the HDD 78 when not in operation, and is read into the RAM 73 and activated by inputting a startup command from the keyboard 76 of the control device 32. In the following description, the statement "proceed to step SXXX" between each step may be omitted.
Steps S601 to S612 are processes for executing the pyrolysis treatment program read into the RAM 73 under the control of the CPU 71 of the control device 32. On the other hand, steps S621 to S628 are processes executed by each device (for example, in step S621, the input device A63, in step S622, the shredder 2 and conveyor 3, etc. will be specified in the explanation of each step below), or each valve or This process is executed by each device based on a control signal that an actuator attached to each solenoid valve receives from the control device 32 via the communication line 55, or each sensor sends a temperature signal to the control device 32 via the communication line 55. This is a processing step of transmitting information or humidity information, or a processing step of each pressure gauge transmitting pressure information to the control device 32 via the communication line 55. The above is the same for the other flowcharts (the steps in the right column after step S720 in FIG. 7, after step S820 in FIG. 8, after step S920 in FIG. 9, and after step S1020 in FIG. 10).

First, the operator starts up the control device 32, loads the control application stored in the HDD 78 into the RAM 73, and starts processing. First, in step S621, the input device A63 inputs the organic waste 1 into the large funnel-shaped receptacle of the shredder 2. Note that, of course, it is also possible to input the organic waste 1 manually. Next, in step S601, the control device 32 sends activation signals to the shredder 2 and conveyor 3, respectively, and the process proceeds to step S602. On the other hand, in step S622, the shredder 2 starts shredding the organic waste 1 in response to the received activation signal, and in step S623, the conveyor 3 activated in response to the received control signal transports the shredded organic waste 1 and heats it. The shredded organic waste 1 is put into the decomposition furnace A4.

In step S602, the control device 32 receives the temperature information of the environmental temperature measured by the temperature sensor C37, receives the environmental humidity measured by the humidity sensor 53, stores each in the work area of the RAM 73, and stores the actual temperature (in degrees Celsius). ) is converted into actual humidity (relative humidity) and stored in the work area of the RAM 73, and then the process proceeds to step S603.
In step S603, the control device 32 sends an open signal to the direct air flow valve 47, the control device 32 sends a start signal to the blower 40, and further the control device 32 sends an ignition signal to the ignition device 5. Furthermore, the control device 32 sends a small opening signal from a 1/4 open signal to a 1/2 open signal to the butterfly valve 49 in accordance with the latest pressure value of the pressure gauge A60 stored in the work area of the RAM 73. , the process advances to step S604. Here, "according to the latest pressure value of the pressure gauge A60" means that the pressure value of the pressure gauge A60 stored in the work area of the RAM 73 is read, and if the pressure is a predetermined pressure (for example, 5 atmospheres or more), the butterfly is activated. A small opening signal is sent to the valve 49, and if the pressure is less than a predetermined pressure, the hydrogen-containing gas generated by the pyrolysis furnace B12 is directed to the storage chamber 34 via the hydrogen-containing gas control valve by the pressure of the suction pump 56. This means that the butterfly valve 49 remains closed until the pressure (for example, 10 atmospheres) or more is accumulated. In addition, here, for example, the 1/4 open signal means, for example, when the standard pressure of the storage chamber 34 (the standard value of the maximum pressure maintained in normal operation) is 20 atm, the 1/4 open signal is It means the ratio when the internal pressure is 1.2 atm and the delivery amount when the valve is fully open (for example, 240 liters per minute) is 1, and the 1/4 open signal means 60 liters per minute.
On the other hand, in step S624, the direct air flow valve 47 that has received the open signal changes from the closed state to the open state, the blower 40 that has received the activation signal starts and starts blowing a little stronger air, and the ignition device 5 that has received the ignition signal is ignited to start the combustion of the organic waste 1 in the pyrolysis furnace A4, and when the butterfly valve 49 receives a small opening signal, the butterfly valve 49 responds to the received small opening signal from the chamber 34. A quantity of hydrogen-containing gas in storage chamber 34 is injected into thermal reactor A4 to aid combustion.
In step S604, the control device 32 sends an open signal to solenoid valve B25 and a close signal to both solenoid valve A24 and solenoid valve C26, and advances the process to step S605. On the other hand, in step S625, the solenoid valve B25 that has received the open signal is changed from the closed state to the open state, and the solenoid valve A24 and the solenoid valve C26 that have received substantially the same timing close signal are both closed. As a result, the exhaust gas in the initial combustion state is discharged through the cyclone 27, the flue gas desulfurization device 28, the wet scrubber 29, the dry scrubber 30, and the chimney 31. The control device 32 is
In step S605, using the converted environmental temperature and environmental humidity acquired in step S602 and stored in the work area of the RAM 73, and further transmitting an open signal to the hydrogen-containing gas control valve 35 in step S604, The predetermined time required for initial heating is calculated by taking into consideration the pressure value of the pressure gauge A60, and it is determined whether this predetermined time has elapsed since the ignition start time of the ignition device 5 in the control parameter history storage section. If it is determined that the predetermined time has not passed (No in step S605), the same state is maintained until the predetermined time has elapsed, and if it is determined that the predetermined time has elapsed (Yes in step S605), the process advances to step S606. The lower the environmental temperature is, the longer the "predetermined time" required for initial heating becomes, and the higher the environmental humidity is, the longer it becomes. Also, if the pressure value of pressure gauge A60 is high, a large amount of hydrogen-containing gas is released during the initial heating stage. Therefore, it becomes shorter. After this predetermined time has elapsed, in many cases, the organic waste 1 is in a state where it continues to burn stably.

In step S606, the control device 32 transmits an extinguishing signal to the ignition device 5, and further transmits a control signal to the blower 40 to change the air blowing from the blower 40 from a slightly strong wind to a moderate wind, and advances the process to step S607. . On the other hand, in step S626, the igniter 5 extinguishes the fire in response to the received extinguishing signal, and the blower 40 changes its air flow to a medium level.
In step S607, the control device 32 sends a close signal to the solenoid valve B25, an open signal to both the solenoid valve A24 and the solenoid valve C26, and further sends a small open signal (1/8 open signal to 1/8 open signal to the butterfly valve 49). /4 open signal), and the process advances to step S608. The restriction based on the latest pressure value of the pressure gauge A60 is the same as in step S603. On the other hand, in step S627, the solenoid valve B25 that has received the close signal changes from the open state to the closed state, and the solenoid valve A24 and the solenoid valve C26 that have received substantially the same timing open signal both become open states. As a result, the high temperature gas generated in the pyrolysis furnace A4 is introduced into the heat exchanger 6 through the pipe A42, and the temperature of the pyrolysis furnace B12 begins to rise. In step S627, the pyrolysis process proceeds in both the pyrolysis furnace A4 and the pyrolysis furnace B12. In step S608, the control device 32 determines the temperature of the temperature sensor A33 attached to the pyrolysis furnace B12 in step S629 by converting the temperature signal received from the temperature sensor A33 into the latest temperature sensor stored in the work area of the RAM 73. The converted temperature of A33 is read, and the furnace temperature of the pyrolysis furnace B12 is estimated from there, and the latest pressure value of the pressure gauge A60 (pressure value of the storage chamber 34) stored in the work area of the RAM 73 is used. Accordingly, a control signal for adjusting the opening degrees of the butterfly valves 49 and 50 is transmitted to the butterfly valves 49 and 50. Specifically, if the temperature is lower than the standard operating temperature, the opening degree will be opened more to increase the temperature inside the pyrolysis furnace B12, and if it is higher than the standard operating temperature, the opening degree will be closed more to increase the temperature inside the pyrolysis furnace B12. An attempt is made to lower the temperature inside the furnace B12. In step S630, this adjustment stabilizes the temperature inside the pyrolysis furnace B12, and also stabilizes the flow rate of the hydrogen-containing gas stored in the storage chamber 34 through the pipe D and the hydrogen-containing gas control valve 35.
However, if the pressure in the storage chamber 34 drops below a predetermined pressure value (for example, 5 atmospheres), an exception process is executed in which new organic waste 1 is input from the input device A63 and the process returns to step S601. If the organic waste 1 is to be manually added, a message and an alarm sound are displayed on the screen of the display 65 of the control device 32 to prompt the user to input the organic waste 1 manually, and the process proceeds to step S609. In step S609, it is determined whether the temperature inside the pyrolysis furnace B12 is less than the minimum operating temperature using the converted temperature of the temperature sensor A33, and if it is determined that it is less than the minimum operating temperature, the process is The process advances to S610, where the temperature raising process for the pyrolysis furnace B12 is executed, and then the process returns to step S608. Details of the temperature raising process of the pyrolysis furnace B12 will be explained with reference to the flowchart of FIG. If it is determined in step S609 that the temperature is not lower than the minimum operating temperature, the process proceeds to step S611, and it is determined whether the internal temperature of the pyrolysis furnace B12 exceeds the maximum operating temperature. If the maximum operating temperature has not been exceeded, the process returns to step S608, and if the maximum operating temperature has been exceeded, the process proceeds to step S612, a process of lowering the temperature of the pyrolysis furnace B12. Details of the temperature lowering process of the pyrolysis furnace B12 will be explained with reference to the flowchart of FIG. This concludes the explanation of FIG.

FIG. 7 is a diagram showing a flowchart of thermal decomposition treatment and primary discharge of biomass, which is a raw material for biochar. In the following description, the statement "proceed to step SXXX" between each step may be omitted.
Steps S701 to S712 are processes executed under the control of the CPU 71 of the control device 32. On the other hand, from step S720 to step S733, each device (in step S720, the input device B64, in step S721, the shredder drying device 11, etc. will be specified in the explanation of each step below) or the actuator attached to each device connects the communication line 55. This is a process executed based on a control signal received from the control device 32 via the control device 32. Alternatively, each sensor transmits temperature information or humidity information to the control device 32 at predetermined time intervals via the communication line 55, or each pressure gauge transmits pressure information to the control device 32 at predetermined time intervals. This is a processing step.

First, the operator starts the biomass thermal decomposition treatment and primary discharge treatment program shown in FIG. 7, and loads this application stored in the HDD 78 into the RAM 73 to start the process. First, in step S720, the charging device B64 charges the biomass resource 8 into the large funnel-shaped receptacle of the shredder drying device 11. Note that it is of course possible to input the biomass resources 8 manually. Next, in step S700, the control device 32 obtains the converted environmental temperature value and environmental humidity value obtained from the temperature sensor C37 and the humidity sensor 53 and stored in the work area of the RAM 83, and stores them in the variable area of the program. The process advances to step S701. In step S701, the control device 32 sends a start signal to the shredder drying device 11, and the process proceeds to step S702. On the other hand, in step S721, the shredder drying device 11 starts cutting and drying the biomass resource 8 in response to the received activation signal. On the other hand, in step S702, the control device 32 transmits a start signal to the nitrogen production machine 22, and the process proceeds to step S703. In step S722, the nitrogen production machine 22 is activated, takes in air and starts producing nitrogen, and stores the produced nitrogen in a tank (not shown) within the nitrogen production machine 22.

In step S703, a start signal for the conveyor 9 is transmitted after the estimated drying completion time based on the environmental temperature value and environmental humidity value obtained in step S700 has elapsed, and the process proceeds to step S704. In step S723, the conveyor 9 receives a start signal and transports the shredded and dried biomass resource 8 from the shredder drying device 11 to the electromagnetic valve D10, which is the input port to the pyrolysis furnace B12. In step S704, the control device 32 transmits an opening signal for the electromagnetic valve D10, and the process proceeds to step S705. In step S724, the received open signal opens the electromagnetic valve D10, and the biomass resource 8 is introduced into the pyrolysis furnace A4 by gravity. In step S705, the control device 32 transmits an opening signal for the nitrogen injection valve 23 to the nitrogen production machine 22, and the process proceeds to step S706.
In step S725, the nitrogen injection valve 23 of the nitrogen production machine 22 is opened by the received open signal, the produced nitrogen is injected into the pyrolysis furnace B12, and the air that originally existed is discharged through the electromagnetic valve D10 etc. be done. In step S706, the control device 32 transmits a closing signal for the electromagnetic valve D10, and the process proceeds to step S707. In step S726, the electromagnetic valve D10 is closed by the received closing signal, and in step S727, the temperature of the pyrolysis furnace B12 rises to about 350°C to 450°C due to the heat propagated from the heat exchanger 6, and the biomass resource 8 is substantially It is thermally decomposed under oxygen-free conditions. Next, in step S707, the control device 32 performs a pyrolysis process calculated using the converted environmental temperature and humidity stored in the work area of the RAM 73 and the temperature of the pyrolysis furnace B12 sent from the temperature sensor A33. It is determined whether the time has elapsed, and if it is determined that the time has elapsed, the process advances to step S708. If it is determined that the time has not elapsed, the process remains in step S707 and waits until it has elapsed.

Next, in step S708, the control device 32 transmits a closing signal to close the electromagnetic valve F17 serving as the biochar outlet of the biochar cooling device 16, and the process proceeds to step S709. On the other hand, the solenoid valve F17 is closed in step S728, and the temperature information from the temperature sensor A33 is transmitted to the control device 32 in step S729. Next, in step S709, the temperature of the pyrolysis furnace B12 is calculated based on the temperature information received by the control device 32, and the process proceeds to S710. In step S710, the control device 32 transmits an opening signal for the electromagnetic valve E13, and the process proceeds to step S711. On the other hand, the electromagnetic valve E13 that received the opening signal opens in step S730, and the biochar falls into the cooling device 16 due to gravity in step S731. In step S711, the control device 32 transmits a signal to close the nitrogen injection valve 23, and the process proceeds to step S712. In step S712, the control device 32 transmits a closing signal for the electromagnetic valve E13. On the other hand, in step S732, the nitrogen input valve 23 is closed, and in step S733, the solenoid valve E13 is closed, and the biochar production and primary discharge process are completed. This concludes the explanation of FIG.

FIG. 8 is a diagram showing a flowchart of biochar cooling treatment and secondary discharge. In the following description, the statement "proceed to step SXXX" between each step may be omitted.
Steps S801 to S811 are processes executed under the control of the CPU 81 of the control device 32. On the other hand, from step S820 to step S831, each device (in step S820, the cooling water temperature sensor B36, in step S821, the cooling water cutoff valve 15, etc. will be specified in the explanation of each step below) or the actuator attached to each device communicates. This is a process executed based on a control signal received from the control device 32 via the line 55. Alternatively, each sensor transmits temperature information or humidity information to the control device 32 at predetermined time intervals via the communication line 55, or each pressure gauge transmits pressure information to the control device 32 at predetermined time intervals. This is a processing step.

First, in step S820, the cooling water temperature sensor B36 transmits temperature information to the control device 32. In step S801, the control device 32 receives temperature information, stores it in the work area of the RAM 73, and advances the process to step S802. In step S802, the control device 32 transmits open information of the cooling water cutoff valve 15 (valve on the water outlet side of the cooler), and advances the process to step S803. In step S821, the cooling water cutoff valve 15 is opened, and the remaining cooling water in step S822 is discharged. In step S803, the control device 32 transmits a close signal for the cooling water cut-off valve 15 after a time period during which water can be discharged has elapsed, and then in step S804 transmits an open signal for the cooling water inlet valve 19, and the process proceeds to step S805. After waiting for the time required to fill the cooling water in step S805, the process advances to step S806. On the other hand, the cooling water cutoff valve 15 is closed in step S823, the cooling water inlet valve 19 is opened in step S824, and new cooling water is filled into the cooling device 16 in step S825. In step S806, the control device 32 transmits a closing signal for the cooling water inlet valve 19, and the process proceeds to step S807. The cooling water inlet valve 19 that received the close signal in step S826 closes, and the biochar cooling process proceeds in step S827. In step S828, temperature information from the cooling water temperature sensor B36 is transmitted to the control device 32.

In step S807, the control device 32 determines the cooling water temperature in step S801 (approximately equal to the temperature of the cooling device 16), the temperature of the latest temperature sensor A33 stored in the work area of the RAM 73, and the cooling capacity of the cooling device 16. It is determined whether the cooling time has elapsed. It is determined whether the cooling time has elapsed. If it is determined that the cooling time has elapsed, the process advances to step S808. If it is determined that the cooling time has not elapsed, the process remains in step S807 and waits until the cooling time has elapsed. In step S808, the control device 32 acquires the latest information of the temperature sensor B36 that measures the temperature of the cooling device from the work area of the RAM 73, and in step S809, based on the temperature of the cooling device, it is determined whether or not cooling can be completed. If the process cannot be completed, the process returns to step S802, the cooling water is replaced, and the cooling process is restarted. If cooling can be completed, the process advances to step S810. In step S810, the control device 32 transmits an open signal for the solenoid valve F17, and in step S829, the solenoid valve F17 for taking out the biochar is opened based on the open signal, and in step S830, the biochar is taken out by a machine for taking out the biochar or manually. Finish processing. This concludes the explanation of FIG.

Next, FIG. 9 is a flowchart of the temperature raising process of the pyrolysis furnace B12, and is a detailed flowchart of step S610 in FIG. Hereinafter, explanations of steps that are the same as those in the process of FIG. 6 will be omitted. Furthermore, in the following explanation, the description "proceed to step SXXX" between each step may be omitted.
Steps S900 to S904 are processes for adding and burning new organic waste 1 as fuel to increase the amount of hydrogen-containing gas and raise the temperature of the pyrolysis furnace B12. Step S920 is similar to step S621 in FIG. 6, so a description thereof will be omitted.
Step S900 is similar to step S602 in FIG. 6, so a description thereof will be omitted.
Step S901 and step S902 correspond to step S601 in FIG. 6, so their explanation will be omitted. Step S920 is a process for charging the organic waste 1 into the input port of the shredder 2, and corresponds to step S621 in FIG. 6. Step S921 corresponds to step S622 in FIG. 6, and step S922 is a process for starting the conveyor 3 and charging the organic waste 1 into the pyrolysis furnace A4, and corresponds to the latter half of step S622 and step S623 in FIG.
Step S903 is similar to step S603 in FIG. 6, except that a control signal for increasing the wind force of the blower 40 is sent to the blower 40. In step S923, the wind force of the blower 40 is changed to strong. In step S904, a stop signal for the shredder 2 and a stop signal for the conveyor 3 are transmitted from the control device 32, and the process proceeds to step S905. In step S924, the shredder 2 and conveyor 3 are stopped. In step S925, temperature information from temperature sensor A33 is transmitted to control device 32. In step S905, the temperature information of the temperature sensor A33 is converted to the actual temperature in degrees Celsius of the pyrolysis furnace A4 and stored in the work area of the RAM 73, and as in step S609 of FIG. 6, the temperature of the pyrolysis furnace B12 is lower than the minimum operating temperature. If the temperature is lower than the minimum operating temperature, the process advances to step S906, and if the temperature is not lower than the minimum operating temperature, the process waits.

In step S906, an open signal is sent to open at least one of the butterfly valves 49 or 50, and in step S927, at least one of the butterfly valves 49 or 50 is opened, whereby the storage is stored in the storage chamber 34. The hydrogen-containing gas thus prepared is introduced into the pyrolysis furnace A4, the flame is made stronger, and the process proceeds to step S907. Step S907 is a process of transmitting an open signal for the air tank valve 51, and in step S927 transmitting an open signal to open the air tank valve 51, and increasing the flame intensity of the pyrolysis furnace A4 by stepping. The process advances to step S908. In step S928, temperature information from temperature sensor A33 is transmitted to control device 32.
In step S908, similarly to step S905, it is determined whether the temperature of the pyrolysis furnace B12 is lower than the minimum operating temperature. If the temperature is lower than the minimum operating temperature, the process proceeds to step S909, and if it is not lower than the minimum operating temperature, the process waits. In step S909, as the final temperature raising means, an ignition signal of the ignition device 5, which is normally used at the start of operation, is transmitted. In step S929, the ignition device 5 ignites and starts heating. In step S930, the temperature sensor A33 temperature information is sent to the control device 32 again, and in step S910, the control device 32 determines whether the temperature of the pyrolysis furnace B12 exceeds the operating standard temperature 1, and if it exceeds the operating standard temperature 1, performs processing. The process proceeds to step S911, and if the temperature does not exceed the operating standard 1 temperature, the process ends. The standard operating temperature 1 means the median of the expected temperature range of the pyrolysis furnace B12 during normal operation, and means, for example, around 500 degrees Celsius. In step S911, the control device 32 sends an extinguishing signal to the ignition device 5, a close signal to the air tank valve 51, a close signal to the butterfly valve 49, and a low air volume control signal to the blower 40. do. In step S931, the ignition device 5 extinguishes the fire based on each received control signal, the air tank valve 51 is closed, the butterfly valve 49 is closed, the air volume of the blower 40 is changed to weak, and the process ends. This concludes the explanation of FIG.

FIG. 10 is a diagram showing a flowchart of a temperature lowering processing program for the pyrolysis furnace B12, and is a detailed flowchart of step S612 in FIG. Since the quality of the organic waste 1 is not constant, the high temperature gas after combustion of the organic waste 1 in the pyrolysis furnace A4 may reach a higher temperature than expected. In that case, the amount of heat transmitted from the heat exchanger 6 to the pyrolysis furnace B12 may increase, and the temperature inside the pyrolysis furnace B12 measured by the temperature sensor A33 may become higher than expected. In such a case, a temperature-lowering processing program is a processing program that can be used for temperature-raising processing of the pyrolysis furnace B12, which may occur more frequently, without wasting thermal energy as much as possible. In the following description, the statement "proceed to step SXXX" between each step may be omitted. Note that XXX is an Arabic numeral.

First, in step S1000, the control device 32 stores the environmental humidity received from the humidity sensor 53 and converted into the actual relative humidity and stored in the work area of the RAM 73, and the environmental humidity received from the temperature sensor C37 and converted into the actual relative humidity. The environmental temperature stored in the work area of the RAM 73 is stored in variable areas. In step S1001, the control device 32 transmits a close signal to the butterfly valve 49 and butterfly valve 50. In step S1021, the butterfly valve 49 and the butterfly valve 50 that supply hydrogen-containing gas from the storage chamber 34 to the pyrolysis furnace A4 are both closed, and no hydrogen-containing gas is supplied to the pyrolysis furnace A4. In step S1002, the control device 32 transmits a control signal to reduce the air volume of the blower 40, and in step S1022, the air volume of the blower 40 is changed to low. In step S1003, the control device 32 transmits a closing signal to close the air tank valve 51, and in step S1023, the air tank valve 51 is closed. In step S1004, the control device 32 transmits a stop signal for the conveyor 3, and in step S1024, the conveyor 3 is stopped. In step S1025, the temperature information of the temperature sensor A33 is transmitted to the control device 32, and the control device 32 converts the temperature information received from the temperature sensor A33 into the actual temperature in degrees Celsius, and then stores the latest temperature of the pyrolysis furnace B12 in the work area of the RAM 73. Save as. In step S1005, the control device 32 determines whether the latest temperature of the pyrolysis furnace B12 in the work area of the RAM 73 exceeds the maximum operating temperature (for example, 430° C.), and if it exceeds the maximum operating temperature, the process proceeds to step The process advances to S1006, and if the maximum operating temperature has not been exceeded, the process ends. The maximum operating temperature means a temperature that is about 20° C. lower than the maximum temperature that does not adversely affect the quality of the biochar produced and does not adversely affect the life of the thermal reactor B12, temperature sensor A33, etc. In step S1006, the control device 32 transmits an open signal to the solenoid valve B25, and in step S1026, the solenoid valve B25 is opened. In step S1007, the control device 32 sends a close signal to the solenoid valve A24 and the solenoid valve C26, and in step S1027, the solenoid valve A24 and the solenoid valve C26 are closed, and the high temperature gas after the combustion of the organic waste 1 is directly passed from the cyclone 27. The exhaust gas is discharged from the chimney 31 through the flue gas desulfurization device 28 and the like. In step S1028, the latest temperature of the pyrolysis furnace B12 is stored in the work area of the RAM 73 as in step S1025. In step S1008, the control device 32 determines whether the latest temperature of the pyrolysis furnace B12 in the work area of the RAM 73 exceeds the operating standard temperature (for example, 410°C), and if it exceeds the operating standard temperature, waits for a predetermined time. However, if the operating standard temperature is not exceeded, the process advances to step S1009. In step S1009, the control device 32 transmits a 1/4 open signal (an angle for supplying hydrogen-containing gas in an amount of about 1/4 of the fully open state at an opening degree of about 1/6 to 1/8 of the fully open state) to the butterfly valve 49. Then, the process immediately advances to step S1010. Instead of transmitting the half-open signal to the butterfly valve 49, it may be transmitted to the butterfly valve 50. In step S1029, the butterfly valve 49 is opened to 1/4, and hydrogen-containing gas is again provided to the pyrolysis furnace A4. In step S1030, similarly to step S1025, the temperature information of the temperature sensor A33 is transmitted to the control device 32, and the control device 32 converts the temperature information received from the temperature sensor A33 into the actual temperature in degrees Celsius, and stores the latest information in the work area of the RAM 73. The temperature is stored as the temperature of the pyrolysis furnace B12. In step S1010, the control device 32 again determines whether the temperature of the latest pyrolysis furnace B12 in the work area of the RAM 73 exceeds the maximum operating temperature, and if it exceeds the maximum operating temperature, sends a close signal to the butterfly valve 49. After transmitting and waiting for a predetermined time, the butterfly valve 49 is fully closed. If it is determined in step S1010 that the maximum operating temperature has not been exceeded, the process immediately advances to step S1011. In step S1011, the control device 32 sends a close signal to the solenoid valve B25, an open signal to the solenoid valve A24, an open signal to the solenoid valve C26, and a close signal to the air tank valve 51. In step S1031, solenoid valve B25 is closed, solenoid valve A24 and solenoid valve C26 are both opened, and air tank valve 51 is closed, returning to the normal operating state. This concludes the explanation of FIG.

FIG. 11 is a diagram showing a flowchart of detailed processing of learning processing in the learning device 39.
In the following description, the statement "proceed to step SXXX" between each step may be omitted.
Steps S1101 to S1106 are processes executed under the control of the CPU 81 of the learning device 39. Step S1121 is a process executed under the control of the CPU 71 of the control device 32. In step S1121, the control device 32 transmits control parameter history information, and in step S1101, the learning device 39 receives the control parameter history information from the control device 32, and stores it in the control parameter history storage unit 69 of the hard disk 88 in FIG. do. In steps S1102 and S1103, the control parameter history information is read into the RAM 83, and learning data is generated from the control parameter history information and stored in the learning data storage section 67 of the hard disk 88 in FIG. Specifically, in step S1102, if the time from ignition to extinguishing of the ignition heating device in the control parameter history information exceeds a predetermined time, or if the time from the opening time of solenoid valve A24 to the opening time of solenoid valve D10 is determined to be If the time is exceeded, the flag of the negative example learning data for that processing cycle is turned on. In step S1103, learning processing is executed based on the analysis result in step S1102.
In step S1104, learning completion determination processing is executed.

Specifically, as a first simple method, actual control parameter history information and optimal parameters after learning are compared at two points to determine whether learning has ended. The first is the execution time of one cycle of biochar production process during past operation before learning, and one cycle of biochar production after learning under the same or similar environmental temperature and humidity conditions and the same input amount of biomass resource 8. This is a comparison of process execution times. The second is the input amount of organic waste 1 and the ignition time of the ignition device 5 during the past operation before learning, and the same or similar environmental temperature and humidity conditions and the same input amount of biomass resource 8. This is a comparison between the input amount of organic waste 1 and the heating time of the igniter 5 in one cycle after learning. For example, if these comparison values indicate that the processing time will be reduced by about 30% compared to before learning, or the amount of organic waste 1 input per cycle and the ignition time of igniter 5 can be reduced by about 20%, learning will be performed. end. Note that if the learning process is repeated multiple times and the determination result is worse than the previous parameter, it is determined that overfitting has occurred, and the previous parameter is set as the optimal parameter. If it is determined that learning can be completed, the process advances to step S1105, and if it is determined that learning cannot be completed, the process returns to step S1103.
In step S1105, the created optimal parameters are stored in the optimal parameter storage section 69 of the hard disk 88.
In step S1106, the created optimal parameters are transmitted to the control device 32 via the communication line 55. In step S1122, the control device 32 stores the received optimal parameters in the optimal parameter storage section 52 of the HDD 78.

As a second method, it is possible to do the following. FIG. 12 shows a flowchart of the parameter optimization process. Steps S1221 to S1223 are processes executed under the control of the CPU 81 of the learning device 39, and step S1221 is a process executed under the control of the CPU 71 of the control device 32.
In step S1221, control parameter history information is transmitted from the control parameter history storage section 38 of the control device 32 to the learning device 39 via the communication line 55, and the learning device 39 stores the received control parameter history information in the learning data storage section 67. do.
In step 1201, actual control parameter history information is read from the learning data storage unit 67, and the quality class of the organic waste resource 1 as a fuel for each treatment cycle is classified into five levels. The purpose of classifying the quality of the organic waste resource 1 as a fuel is to classify the quality class of the organic waste resource 1 and the storage chamber 34, since the quality of the organic waste resource 1 is expected to differ for each treatment cycle. It is necessary to determine optimal parameters depending on the amount of hydrogen-containing gas stored.
Specifically, the classification is determined by the following method.
1) Input weight of organic waste resource 1 The greater the input weight of organic waste resource 1, the more heat is generated by pyrolyzing and gasifying organic waste 1 and burning it.2) The pressure of pressure gauge A60 increases. The amount of hydrogen-containing gas released from the storage chamber 34 calculated from the time course and the valve openings of the butterfly valves 49 and 50 The greater the amount of hydrogen-containing gas released, the more heat is generated. Although the amount of heat generated in pyrolysis furnace A4 increases,
3) Temporal change in temperature of temperature sensor A33 of pyrolysis furnace B12 Is the temperature rising quickly and is there a high or low percentage of the temperature being maintained on the high temperature side during the treatment process? 4) Temperature sensor that measures the environmental temperature Temporal change in temperature of C37 The lower the environmental temperature, the more heat is radiated from the pyrolysis furnace B12 to the environment, which is a disadvantageous factor 5) Temporal change in humidity of the humidity sensor 53 that measures environmental humidity The higher the environmental humidity It is expected that the moisture content of the organic waste resource 1 to be input will increase as the moisture content increases, and the higher the moisture content, the more heat will be taken away by the latent heat of vaporization of moisture out of the total heat generated in the pyrolysis furnace A4. From the conditions of 1) 2) 4) and 5) above and the rise in temperature of the pyrolysis furnace B12 from the start of the treatment cycle of 3) above, the fuel of organic waste resource 1 for each past treatment cycle The upper and lower limits of the average temperature rise rate at startup are determined for each quality class, each input weight, each environmental temperature, and each environmental humidity, and are stored in the hard disk 88 of the learning device 39.

In step 1202, determining the optimum parameter for the supply amount of hydrogen-containing gas according to the amount of hydrogen-containing gas stored in the storage chamber 34 at the start of the treatment process 1) If the amount is small, increase the input weight of organic waste resource 1 to the maximum possible input amount, pyrolyze the organic waste resource 1, combust it, and generate high-temperature gas. It is necessary to quickly raise the temperature and increase the amount of hydrogen-containing gas stored in the storage chamber 34. The overall processing time will be slightly longer.
2) If the amount of hydrogen-containing gas stored in the storage chamber 34 at the start of the treatment process is large, the input weight of the organic waste resource 1 is an amount commensurate with the dry weight of the biomass resource 8 input into the pyrolysis furnace B12. By charging a large amount of the hydrogen-containing gas stored in the storage chamber 34, it is possible to quickly raise the temperature of the pyrolysis furnace B12 and shorten the overall processing time.
3) If the amount of hydrogen-containing gas stored in the storage chamber 34 at the start of the treatment process is moderate, the input weight of the organic waste resource 1 is commensurate with the dry weight of the biomass resource 8 input into the pyrolysis furnace B12. The amount of hydrogen-containing gas stored in the storage chamber 34 can be injected in a large amount for a short period of time from the start of the input timing of the treatment cycle, and then it can be slightly reduced, thereby raising the temperature of the pyrolysis furnace B12 quickly. This makes it possible to reduce the overall processing time and suppress the amount of hydrogen-containing gas released.
4) Read the start/stop time of the suction pump 57 and the change in pump rotation speed from the control parameter history information, and start the treatment cycle according to the total accumulated amount of hydrogen-containing gas for each treatment cycle and the temperature of the pyrolysis furnace B12. The amount of hydrogen-containing gas accumulated per unit time is calculated according to the time elapsed since then.

In step 1203, optimal parameters from steps 1 and 2 are determined.
The overall optimal parameters are determined from the results of steps 1 and 2 above. Based on the accumulated amount of hydrogen-containing gas at the start of the treatment cycle determined in step 2 and the accumulated amount of hydrogen-containing gas per unit time according to the elapsed time from the start of the treatment cycle according to the temperature of pyrolysis furnace B12. , the supplyable amount of hydrogen-containing gas for each quality class and the amount of hydrogen-containing gas accumulated at the start of the processing cycle and for each elapsed time from the start of the processing cycle is calculated and stored in the hard disk 88 of the learning device 39 .
