DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the accompanying drawings. (Embodiment 1) FIGS. 1 and 2 show a flush-type temporary toilet to which the human waste treatment mechanism of the present invention is applied. In addition to the temporary toilet,
Of course, it can be applied to general toilet human waste treatment. In addition, the flush-type temporary toilet is normally used for human waste.
Approximately 20 times as much washing water is used. The human waste treatment mechanism of this embodiment includes a human waste storage tank 1 for storing human waste before treatment, a human waste treatment tank 3 for storing a heating medium 2 having a specific gravity of more than 1 and a boiling point higher than that of water, and an offensive odor. And an exhaust deodorizing cylinder 5 for filling and containing a granular catalytic oxidation medium 4 for deodorizing the vapor and smoke of urine. The human waste treatment tank 3 is installed in a horizontal direction, and the exhaust odor eliminating cylinder 5 is installed in a vertical direction, and is arranged in an L shape as a whole. When the temporary toilet is used, human waste is first stored in the human waste storage tank 1 from the toilet bowl 6. The human waste storage tank 1 for storing the human waste before this treatment circulates or agitates the human waste in the tank to make semi-solid components such as toilet paper, dust paper, and tissue contained in the human waste into a fluid state, and It is supplied to the processing tank 3. This is because semi-solid components such as toilet paper cause blockage / failure of the metering pump 7 for sending urine from the human waste storage tank 1 to the human waste processing tank 3. Therefore, in this embodiment, the submersible circulation pump 8 that can circulate semi-solid components such as toilet paper is installed inside the urine storage tank 1 so that the semi-solid components can be dispersed during the circulation operation of the submersible circulation pump 8. did. Therefore,
There is an advantage that the human waste containing the semi-solid component can be dispersed / uniformized and stably supplied to the human waste treatment tank 3 by the metering pump 7. That is, human waste is circulated by the submersible circulation pump 8 installed in the human urine storage tank 1, and part of the human urine is supplied to the human urine processing tank 3 by the metering pump 7. The human waste treatment tank 3 has a bottomed sideways semi-cylindrical inner storage portion 9 (see FIG. 2) which stores the heating medium 2 and an open upper side, and a bottomed sideways cylindrical inner side storage portion 9 which covers the inner storage portion 9 so as to be drawn out. It has a double structure with the outer body 10. And
The outer periphery of the outer body 10 is a 2 kW cylindrical electric heater.
It is wrapped with 11 (see Fig. 1). The heat is transferred from the outer main body 10 heated by the electric heater 11 to the inner housing 9, and the human waste treatment tank 3 is heated to raise the temperature of the heating medium 2. Outer body of cylindrical human waste treatment tank 3
The top wall of 10 has a circular opening 12 over a quarter length.
The steam and combustion gas generated from human waste are transferred to the upper exhaust odor eliminating cylinder 5 through the opening 12. Also, the outer main body portion 10 of the human waste treatment tank 3
The pipe from the human waste storage tank 1 is connected to the upper wall of the. As the heating medium 2 having a specific gravity to be retained in the human waste treatment tank 3 of more than 1 and a boiling point thereof higher than that of water, a low melting point alloy such as tin or an alloy thereof can be selected.
As the low-melting point metal, a simple substance of lead or tin, or as the low-melting point alloy, a fusible alloy or the like made of an appropriate combination of lead, tin, bismuth, antimony, indium, cadmium, etc. is suitable. Simple substance (solid at room temperature.
The melting point is 231.9 ° C, the boiling point is 2,270 ° C, and the specific gravity is 7.
28) is used, and it is put in advance in the inner containing portion 9 so that the depth when melted is 1 to 2 cm. By heating the human excrement with the heating medium 2, bumping is prevented, and corrosion of the inner wall of the tank caused by an increase in the concentrated salt concentration of the human excrement is suppressed by the heating medium 2. Then, the temperature of the heating medium 2 is raised,
The human waste supplied to the human waste treatment tank 3 is heated so as to be finally made into a dry powder. The supplied human waste is
Almost no direct contact with the heated human waste treatment tank 3 is made, and the heated heating medium 2 is heated in a stable state with almost no bumping even at the time of evaporative concentration. The reason why almost no bumping occurs is as follows. Since the inner wall of the human waste treatment tank 3 has a small heat capacity, if an attempt is made to treat urine without using the heating medium 2, the temperature of the inner wall of the hot water immediately drops due to the supplied human waste unless the temperature is set to a considerably high temperature. When urine urine is supplied, it boils instantly and causes bumping. On the other hand, when a low melting point alloy having a large heat capacity is used as the heating medium 2 as in this embodiment, when human waste is supplied, the temperature of the heating medium 2 is not so high. The temperature does not immediately drop due to the abundant heat capacity of the stored heating medium 2. When the human waste is evaporated and concentrated, or when the residue thereof is incinerated, steam or smoke that gives off a bad smell of human waste is generated. Therefore, in order to promote high-temperature oxidation of the odorous components in human waste to make them odorless, an exhaust deodorization cylinder 5 for filling and containing the granular contact oxidation medium 4 is installed above the human waste treatment tank 3. The exhaust deodorizing cylinder 5 is heated by a 3 KW cylindrical electric heater 13. In order to improve the ventilation from the human waste treatment tank 3 to the exhaust deodorizing cylinder 5, the sirocco fan 14 (2.6
m ³ / min). Then, the exhaust gas from the human waste treatment tank 3 and the exhaust odor eliminating cylinder 5 is released into the atmosphere by being attracted by the sirocco fan 14, and the upper wall of the outer main body portion 10 of the human waste treatment tank 3 and the inner accommodation portion 9 are separated from each other. Air is always sucked in through a gap (about 1 to 2 mm) intentionally formed between them, and oxygen is supplied to the exhaust deodorizing cylinder 5. It should be noted that since the human waste is gently heated by the heating medium 2 and there is almost no bumpy evaporation, the outer main body of the human waste treatment tank 3 is
No foul odor was leaked to the outside through the gap between the upper wall of 10 and the inner housing 9. The sirocco fan 14 sucks in the exhaust gas (600 to 700 ° C.) from the exhaust odor eliminating cylinder 5 and 10 times as much air as this and discharges it. The final exhaust temperature from the exhaust deodorizing cylinder 5 is 60 to 80 ° C., and is 40 to 60 ° C. or lower at a position 10 to 20 cm from the exhaust port. Also, in order to incinerate the residue of concentrated night soil, the necessary amount of air is insufficient only by the outside air that is naturally taken in by the attraction of the sirocco fan 14, so a small blower for forcibly sending in the combustion air. 16 is provided in the human waste treatment tank 3. In addition, a ring-shaped ferrule (stainless steel band having a width of about 50 mm) is used to suppress the gap between the upper wall of the outer main body 10 of the human waste treatment tank 3 and the inner storage portion 9, and when the human waste is incinerated, the small blower 16 and Sirocco fan 14
Alternatively, balanced ventilation may be performed (not shown). As the granular contact oxidation medium 4, crushed material of volcanic lava (crushed fragments of Sakurajima volcanic lava to about 10 to 30 mmφ), stainless lathe chips (lathe chips), ceramic fine particles or fine particles Etc. can be used. All of them were cheap and had a sufficient deodorizing effect. It should be noted that stainless lathe chips have finite finite lifetime due to rusting over time, whereas lava fragments have the advantage of long life. In this way, the components evaporated from human waste are passed through the exhaust deodorization cylinder 5 while heating 9 kg of the crushed material of the volcanic lava in a state of being heated and red-heated, so that the components of the odor in human waste are deodorized. Is discharged. This makes it possible to increase the surface area of the volcanic lava by granulating it like crushed material without using an expensive oxidation catalyst such as platinum, and to use it in a heated state. It had a great deodorizing effect. Next, the usage state of the human waste processing mechanism of this embodiment will be described. Using the above-mentioned human waste processing mechanism, human waste was processed in the following steps. Step of Evaporating and Concentrating Human Urine While heating the stored heating medium 2 to a temperature of about 100 ° C. or higher, while supplying urine to the human sewage treatment tank 3, a step of evaporating water in the human urine and thereby concentrating human urine Is. That is, the ambient temperature in the night soil treatment tank 3 is 300 ° C.
The heating medium 2 was heated to about 100 ° C. or higher, and human urine was supplied at a flow rate of 20 to 40 cc / min. If the supplied urine becomes excessive, the ambient temperature will drop. Therefore, when the ambient temperature drops to 100 ° C., the sequencer is controlled so that the supply of night soil by the metering pump 7 is stopped. When the human waste supply is stopped and the human urine processing tank 3 evaporates and concentrates human urine, the ambient temperature rises again. The ambient temperature in the human waste treatment tank 3 is 10
When the temperature rises to 0 ° C., the metering pump 7 is activated again to restart the supply of night soil to the night soil processing tank 3. In addition, this evaporation concentration process is an automatic control program using a sequencer,
The timer is set to continue for 4 hours. Also, a sirocco fan installed at the outlet 15 of the exhaust odor eliminating cylinder 5.
By the attraction of 14, the outside air is naturally taken in through the gap in the lid portion of the human waste treatment tank 3. Due to the presence of oxygen in the taken air, the exhaust odor eliminating cylinder 5 is completely burned,
The evaporative gas was sufficiently deodorized. The atmosphere temperature in the exhaust odor eliminating cylinder 5 is set to 700 to 850 ° C. Incineration process of human waste residue The human urine treatment tank 3 is interrupted to supply human waste and the temperature of the heating medium 2 is raised to about 300 ° C. or more to incinerate and dry the concentrated human urine residue by evaporation of water. This is a step of making powder. When the evaporative concentration step has passed for 4 hours, the evaporative concentration step shifts to the incineration step, the metering pump 7 for supplying human urine is stopped by the automatic control program, and the setting of the atmospheric temperature in the human waste treatment tank 3 is changed to 380 ° C. . Along with this transition, the air injection pump (small blower 16) is operated, and air for incineration of the residual human waste in the human waste treatment tank 3 is supplied. When entering the incineration process, the necessary amount of air is insufficient only by the outside air naturally taken in by the attraction of the sirocco fan 14, so the combustion air is sent by the small blower 16. The atmospheric temperature in the exhaust odor eliminating cylinder 5 is set to 500 to 850 ° C. Due to the supply of air by the small blower 16, the concentrated human excrement was oxidatively incinerated, and almost only inorganic substances remained. The residue of night soil treated with the heating medium 2 in the fluidized state remained as a fine, free-flowing dry powder without solidifying in the form of clinker. The residue of the human waste does not solidify in a clinker shape because the human waste hardly contacts the inner wall of the high-temperature human waste treatment tank 3 itself, and most of it is heated by the fluid surface of the molten liquid heating medium 2. Because it is done. Note that the components remaining after evaporating and concentrating human waste are inorganic salts mainly consisting of salt and calcium phosphate, but when human waste is directly incinerated using an incinerator, it is included in the urine as a heat transfer surface of the incinerator. Inorganic salts, etc. are condensed, solidify and burn to become a hard clinker.
This not only lowers the heat transfer efficiency of the incinerator, but also causes corrosion and damage inside the incinerator. Further, the human excrement supplied to the heat transfer surface heated to a high temperature causes bumping, which makes evaporation and concentration very difficult. On the other hand, in this embodiment, a low melting point alloy such as tin or an alloy thereof is used as the heating medium 2 and is put in the urine treatment tank 3 in advance, so that the supplied human waste does not directly touch the high temperature human waste treatment tank 3. Evaporative concentration on the fluid heating medium 2 is performed in a stable state without bumping. When taking out the treated residual ash, the inner storage portion 9 of the night soil treatment tank 3 is pulled out by half or more to the front so that the residual ash on the heating medium 2 is scraped out. Heating medium 2
If the melting point is about 100 to 300 ° C., it is solidified when the residual ash is taken out, so that the work is easy. This removal can be done easily by hand, but it can also be automated by a combination of an air blow and a small cyclone (not shown). In addition, residual ash can be taken out by forming an automatic discharging device using electromagnetic vibration (not shown). Next, the evaluation of the odor of the exhaust gas discharged from the exhaust deodorizing cylinder 5 will be described. When stainless lathe cutting powder was used as the granular catalytic oxidation medium 4, it was possible to completely eliminate odor and smoke at 700 ° C or higher. When lava crushed material was used as the granular contact oxidation medium 4 ... Even at 650 ° C or higher, it was possible to sufficiently deodorize and smokeless. A sensory test by the nose confirmed that the exhaust gas was deodorized as described above, but the evaluation was also made quantitatively as follows. Kitagawa detector (GASTEC
Manufactured by the company, model 801) and gas detector tube (manufactured by the company,
No3L [ammonia 0.5-60 ppm], No11
S [nitrogen oxide NOx 10 to 250 ppm], No5L
[Sulfur dioxide SO _{2 5 to} 100 ppm] was used to measure the exhaust gas. The NOx concentration of nitrogen oxides is 30 when the temperature of the exhaust odor eliminating cylinder is set to 800 to 850 ° C.
~ 50ppm, the temperature of the exhaust deodorizing cylinder 750-78
When it was 0 ° C., it was 10 to 20 ppm. These values sufficiently clear the regulated value of 250 ppm of the Air Pollution Control Law. Ammonia and sulfur dioxide SO ₂ were not detected under any of the above temperature conditions. (Example 2) The same human waste treatment mechanism as in Example 1 was applied to a non-water-washing type temporary toilet. Although stool is diluted by urine in a non-water-washing type temporary toilet, it was possible to quantitatively send urine from the human waste storage tank 1 to the human waste treatment tank 3 by the tube-type metering pump 7. The evaluation of the odor of the exhaust gas discharged from the exhaust deodorizing cylinder 5 will be described. Evaluation was carried out in the same manner as in Example 1. Regarding the ambient temperature of the exhaust odor eliminating cylinder 5,
When the temperature of the exhaust deodorizing cylinder 5 is set to 800 to 850 ° C .... The exhaust gas is odorless, the ammonia concentration is 0 ppm, and NO.
x concentration is 30 to 50 ppm, when the temperature of the exhaust deodorizing cylinder 5 is 750 to 780 ° C .... Exhaust gas is almost odorous, ammonia concentration is 0 to 3 ppm, NOx concentration is 10
~ 20ppm, the temperature of the exhaust deodorization cylinder 5 700 ~ 7
At 50 ° C .... Ammonia odor remained, the ammonia concentration was 40 to 60 ppm, and the NOx concentration was 0 to 5 ppm. These values are 250 regulated by the Air Pollution Control Law.
It sufficiently clears ppm. Sulfur dioxide S
O ₂ was not detected under any of the above temperature conditions. In order to make the exhaust gas almost completely deodorized, it was necessary to set the atmospheric temperature of the exhaust deodorizing tube 5 to a temperature slightly higher than that of the flush toilet. (Embodiment 3) FIG. 3 shows an application of the human waste treatment mechanism of the present invention to a train toilet. This one was installed under the floor of the train. The overall structure is similar to that of the first embodiment,
In this embodiment, both the urine treatment tank 3 and the exhaust odor eliminating cylinder 5 are horizontally long so as to be contained in a low floor of a train. 8 kg of a low melting point fusible alloy (tinting point: 138 ° C., boiling point: 1,500 ° C. or higher, specific gravity: 8.7) made of tin and bismuth or the like is previously put in the night soil treatment tank 3 as a heating medium 2. Besides the heating medium 2, for example, a fusible alloy composed of lead and bismuth (melting point: 124 ° C., boiling point: 1,670 ° C.,
Specific gravity 10.3), easy fusion alloy consisting of lead and indium, etc. (melting point 58 ° C, boiling point 1,500 ° C, specific gravity 9.2)
Etc. may be used. A cylindrical ceramic fiber having a thickness of 8 mm is attached to the inner surface of the tank to prevent corrosion of the inner wall. Then, a 2KW sheath heater (not shown) is provided on the outside of the bottom surface and 1K is provided on the outside of the side surface.
A W sheath heater (not shown) is laid. Further, a rail guide and casters are provided so that the inner housing portion 9 of the human waste treatment tank 3 can be pulled out to the front side when the residual ash is taken out. And after the treatment of human waste,
The human waste treatment tank 3 was pulled out to take out the dry powder inside. Therefore, it is easy to dispose of the dried powder after processing. In the exhaust deodorizing cylinder 5, 10 volcanic lava (of basalt and andesite of Sakurajima) is used as the granular contact oxidation medium 4.
8 kg of crushed pieces of ~ 30 mm size are filled. Since the temperature of the exhaust gas from the exhaust odor eliminating cylinder 5 is relatively low at 40 to 60 ° C. or less, it was safe to install this mechanism under the floor of vehicles such as trains and trains. Next, the usage state will be described. The operation of the human waste treatment mechanism is automatically controlled by a sequencer. This is centered on temperature control by a temperature sensor and temperature controller, and the sequencer control automatically starts when the train pantograph rises in the morning.
The program control includes a self-check of the sequencer, a temperature sensor abnormality, a heater abnormality, etc., and inspections at the start of operation such as confirmation of the storage level of the human waste storage tank 1. Before starting operation after confirming that there are no abnormalities by these start-up checks. First, the incineration process starts with the incineration process. The human waste remaining on the previous day is first incinerated. The ambient temperature of the night soil treatment tank 3 is set to 380 ° C., and the night soil night soil treatment tank 3 is set.
The temperature of the atmosphere in the night soil treatment tank 3 rises until the set temperature is reached or the timer setting for 1 hour is reached. During this time, a small blower (not shown)
By this, the air for combustion is taken in, and the concentrated organic matter in the human waste is oxidized and burned to become powdery residual ash. Evaporative Concentration Step When the incineration step set for a fixed time ends, the process proceeds to the evaporative concentration step, and when the ambient temperature in the human waste treatment tank 3 drops to the newly set 300 ° C., the human waste storage tank 1 to the human waste treatment tank 3 The metering pump 7 for supplying human waste to the human body operates. In order to stably evaporate and concentrate and excrete human waste, a feed rate of the metering pump 7 of about 30 to 60 cc per minute was preferable. If the supply of night soil to the night soil treatment tank 3 becomes excessive, the ambient temperature in the night soil treatment tank 3 will gradually decrease,
When the ambient temperature drops to 100 ° C. or lower, the metering pump 7 for supplying urine is stopped. afterwards,
When the human waste in the human waste treatment tank 3 evaporates and the ambient temperature rises and exceeds 100 ° C. again, the metering pump 7 is activated again. Further, when the night soil in the night soil storage tank 1 is at a low water level, the operation is stopped and the operation is in a standby state until the water level rises sufficiently, and when the water level is restored, the operation is restarted. The evaporative concentration step is set to continue for 4 hours, and after 4 hours, it is switched to the incineration step again. The incineration process and the evaporative concentration process are alternately repeated while the train is in operation. When the pantograph goes down after the train has finished driving, the urine processing mechanism stops. When removing residual ash, human waste treatment tank 3
It is possible to easily carry out the work by pulling out the inner housing portion 9 of this side. The removal of the residual ash could be processed in about 10 minutes using a short time of temporary entry into the train area or train area. Also, the removal of residual ash is done about once every two months,
When I checked the train or train, I was able to scoop it easily with a metal tool such as a rice scoop. The amount of human excrement processed per day (1
For 5 hours operation) 30-60 liters, 2 per hour
It was about 4 liters. According to this product, it is possible to take it out as an extremely small amount of dry powder hygienically once every 1-2 months without taking out untreated human waste as it is in trains, airplanes, temporary toilets, etc. The urine can be treated much more easily than before. It should be noted that the low melting point alloy serving as the heating medium 2 has a large specific gravity although it is shaken when the train is in operation.
As described above, in the processing mechanism and processing method of this human urine,
The heating medium 2 whose specific gravity stored in the human waste treatment tank 3 is higher than 1 and whose boiling point is higher than that of water is heated, and urine is supplied and heated therein. The heated human excrement is finally made into a dry powder. Therefore, there is an advantage that urine can be simply processed.

The present invention having the above-mentioned structure has the following effects. Since the heated human waste is finally made into a dry powder, it is possible to provide a human urine processing mechanism and method capable of processing urine more easily than before.
