If the water flow facility is a facility such as a heat exchanger, if floating substances accumulate on the wall surface of the water flow path, the heat efficiency of the heat exchanger decreases.
In addition, if the flow rate of water flow varies with floating material accumulated on the wall surface of the water flow path, the floating material deposited on the wall surface of the water flow path will peel off, and the separated floating material will flow again through the water flow path. There is. Then, in the water for the paper pulp process, the floating matter that has flowed out again in this way is mixed into the pulp as a solid matter, causing a defect in the paper product. When a defect occurs in the paper product, the productivity of the paper product is deteriorated or the quality of the paper product is deteriorated. Therefore, it is monitored whether or not floating substances are attached to the inner wall of the water flow path such as piping. For example, when the adhesion of the slime floating substances is detected, measures such as adding a slime inhibitor to the water flow path as appropriate are attempted. Has been.

  A method using light is known as a method for monitoring the adhesion of floating substances. In other words, the amount of light that passes through the water that passes through the water passage attenuates as the amount of dirt in the water that passes through the water passage decreases. Therefore, the suspended matter in the water passage is quantified by measuring the amount of transmitted light. can do. In general, in an apparatus including a light-transmitting member that is in contact with water that passes through and a light-emitting body and a light-receiving body that are disposed so as to sandwich the light-transmitting member, light passes through the light-transmitting member. In addition, a method of irradiating a light-transmitting member to a light-transmitting member, causing the light-receiving member to receive light transmitted through the light-transmitting member, and quantifying floating substances in the water that passes through the amount of light received by the light-receiving member is known. It has been.

The industrial water system or industrial waste water system water used in the water flow facility 1 passes through the water flow pipe 2a and the water flow device 2b as main water and is discharged outside the water flow facility 1. At this time, in industrial water-based water, additives such as internal chemicals and fillers, generated slime, etc. are present as floating substances, and these floating substances are the inner walls of the water flow path 2 of the water flow facility 1. It adheres to the water and becomes an adhering substance, and the water passage 2 is soiled.

  The deposit quantification apparatus 10 includes a plurality of branch pipes 5, a plurality of branch sections 3, a plurality of transmission sections 40 each having a plurality of cells 41, an irradiation section 20, a light receiving section 30, and an open / close state. A plurality of branched water blocking units 50 such as valves, a deposit amount quantifying unit 60, a plurality of antifouling means 70, and a photographing unit 80 are provided.

  The plurality of branch pipes 5 are respectively provided in the water flow path 2 of the water flow facility 1 so that a part of the main water of industrial water or industrial wastewater branches into the plurality of branch sections 3 as branch water. The deposit quantification apparatus 10 quantifies the deposit adhering to the water passage 2 using the branched water branched in each of the plurality of branch pipes 5.

  Each branch water branched from each branch pipe 5 is drained out of the deposit quantification apparatus 10 via each branch part 3, each branch water blocking part 50, and each permeation part 40.

As shown in FIGS. 2A and 2B, the transmission part 40 is made of a permeable material so that the light from the irradiation part 20 irradiates the branched water. Each of the plurality of transmission units 40 includes a plurality of columns 41.
2A and 2B, a plurality of columns 41 are arranged in a line, and the column 41 on the end side is displayed in FIG. In FIG. 1, a plurality of columns 41 are arranged in the front-rear direction of FIG. 1, and among these, the foremost column 41 is displayed. Moreover, although the clearance gap is provided between each other of the some column 41, you may adjoin.

Each column 41 has a cylindrical shape such as a cylinder or a square cylinder. As the shape of each column 41, if it is a cylindrical shape that is easy to process, there is little dead space and maintenance is easy.
Each column 41 may be provided with a function (cleaning means) that automatically cleans the wall surface of each column 41 with high-pressure water, compressed air, or chemicals.
Further, by arranging a plurality of columns 41 in a light-shielding housing and irradiating light from the light emitter during measurement, the influence of dirt on the transmissive part 40 due to changes in external light is eliminated, and dirt on the transmissive part 40 It becomes possible to evaluate.

Registered trademark of Chemical Co., Ltd.), transparent PVC having excellent chemical resistance at low cost, glass and the like. Transparent PVC is transparent and inferior to acrylic, but can be used by canceling the blank value.

  As shown in FIG. 1, the tributary section 3 has a drain mechanism that can drain water inside the tributary section 3 in a state where the branch water from the tributary section 3 is blocked by the branch water blocking section 50. Or it has an exchange mechanism which replaces the water in the tributary part 3 with fresh water. The drain mechanism and the replacement mechanism include a valve, and it is preferable to use a solenoid valve and a solenoid valve switching control unit as the valve. When the pressure of the branched water fluctuates, a constant flow valve is installed at the inlet of each column 41 to suppress the pressure change, prevent the exfoliation of the adhering matter, and accurately reproduce the growth of the adhering matter. When the pressure fluctuation of each column 41 is small, a mechanism for adjusting with a manual valve may be provided.

  As shown in FIG. 2A, the irradiation unit 20 includes a plurality of light emitters 20a corresponding to the plurality of columns 41, respectively. Thereby, the irradiation part 20 irradiates the some transmission part 40 with the light of the some light-emitting body 20a, respectively. As each light emitter 20a, an incandescent bulb, a fluorescent lamp, a mercury lamp, a metal halide lamp, a light emitting diode, a laser, a semiconductor laser, or the like can be used. For example, by irradiating a laser beam in a band shape that can irradiate a predetermined width instead of a point, and evaluating the transmitted light and reflected light at that time, the uneven adhesion of a certain range on the column is averaged and converted into data This makes it possible to quantify the amount of dirt adhered more accurately.

The light receiving unit 30 includes a plurality of light receiving elements 30 a respectively corresponding to the plurality of columns 41. The light receiving unit 30 is disposed on the opposite side of the transmission unit 40 from the irradiation unit 20 such that the transmission unit 40 is between the irradiation unit 20 and the light reception unit 30, and the light of the irradiation unit 20 transmitted through the transmission unit 40. Is received. The light receiving unit 30 is, for example, a photoelectric conversion element such as a photodiode that can detect a light transmission amount.
The irradiating unit 20 and the light receiving unit 30 are preferably arranged in a non-contact manner with the plurality of columns 41 so as not to cause malfunction due to the temperature of branching water or condensation.

  As shown in FIG. 1, the adhering matter quantification unit 60 converts the amount of light received by each light receiving element 30 a of the light receiving unit 30 through the transmission unit 40 when the branched water blocking unit 50 blocks the branched water. Based on this, it is a calculation unit that quantifies the amount of deposits on the water flow path 2. The adhering matter amount quantification unit 60 quantifies the amount of adhering matter in the water passage 2 at a predetermined time interval because it quantifies when the branched water blocking unit 50 blocks the branched water.

  The branched water blocking unit 50 is an on-off valve that blocks the flow of branched water in the permeating unit 40. The branch water blocking unit 50 includes an electromagnetic valve that blocks water flow from the tributary unit 3 and an electromagnetic valve switching control unit that controls the electromagnetic valve. The electromagnetic valve switching control unit opens and closes the electromagnetic valve based on the control signal from the deposit amount quantifying unit 60. When the solenoid valve is closed, the branch water from the branch 3 is blocked. When the solenoid valve is open, the branch water from the branch 3 is allowed to flow.

  The imaging unit 80 is a camera that captures an image of the transmission unit 40 when the attached matter amount quantification unit 60 is quantifying. The amount-of-attachment quantification unit 60 calculates the degree of contamination of each transmission unit 40 quantified based on the light received by the light receiving unit 30, and sensory contamination through vision based on the image captured by the imaging unit 80. Calculate the degree.

As shown in FIG. 2 (B), the plurality of dirt preventing means 70 are respectively provided in the plurality of branch sections 3 upstream from the transmission section. Specifically, each of the plurality of branch portions 3 corresponds to each of the plurality of columns 41 via a plurality of antifouling means 70.
Each dirt prevention means 70 is installed on each tributary part 3, for example, each dirt prevention agent injection part 71 for injecting a dirt prevention agent such as a medicine, and downstream of each dirt prevention agent injection part 71. And a stirrer 72 such as a static mixer that stirs the antifouling agent.

  If the types of antifouling agents added to the plurality of antifouling means 70 are made different, the superiority or inferiority of the drug effect of the antifouling agent can be evaluated. According to this evaluation method, it is possible to make a small-scale quantitative evaluation before evaluation with an actual machine, and an effective drug and application method can be examined for each apparatus.

The above deposit quantification apparatus 10 operates as follows.
Usually, when the water flow facility 1 is continuously operated, water for industrial use or industrial waste water is continuously discharged as drainage through the water flow path 2. As for the water flow path 2, an inner wall will become dirty as the water of an industrial water system or an industrial wastewater system flows. And since the branch pipe 5 is connected to the water flow path 2, a part of water of an industrial water system or an industrial wastewater system passes the permeation | transmission part 40 as branch water (water flow process).

  And according to the stain | pollution | contamination of the water flow path 2, the permeation | transmission part 40 also becomes dirty with branch water. However, the branch water is divided into a plurality of branch waters, and each of the plurality of branch waters passes through the plurality of branch parts 3, so that the dirt water is contaminated by each dirt prevention means 70 provided in each branch part 3. An inhibitor is injected into each branch water.

Here, if the types of antifouling agents added to the plurality of antifouling means 70 are different from each other, the superiority or inferiority of the chemical effect of the antifouling agent can be evaluated. According to this evaluation method, it is possible to make a small-scale quantitative evaluation before evaluation with an actual machine, and an effective drug and application method can be examined for each apparatus.
Further, when the dirt preventing means 70 is actuated, the dirt of the transmission part 40 is removed. Therefore, when the measurement is performed again, if the dirt preventing means 70 is acted, a new measurement is performed in a state where the dirt is not present on the transmission part 40. It can be carried out.

  At this time, the light receiving unit 30 receives the light of the irradiation unit 20 that has passed through the transmission unit 40, thereby measuring the light transmission amount of the transmission unit 40 when the branched water is flowing through the transmission unit 40. (Light transmission amount measuring step).

  Next, after a certain time has elapsed, the solenoid valve of the branch water blocking section 50 installed at the pipe inlet of the branch section 3 is actuated (branching water blocking step) to blow the branch water in the branch section 3 pipe. Let Thereby, the branch water blocking unit 50 blocks the water flow of the branch water, so that the branch water from the branch pipe 5 does not flow to the transmission unit 40.

  Next, the drain mechanism or the replacement mechanism is operated to discharge the branched water in the plurality of columns 41, or the fresh water replacement step of replacing the branched water with fresh water. Thereby, in the permeation | transmission part 40, a branch water will be in the absence state, and the permeation | transmission part 40 will be filled with air or fresh water.

  Next, in the irradiation unit 20, the light emitted from the plurality of light emitters 20 a is transmitted through the plurality of columns 41, and the transmitted light is received by the light receiving unit 30. From the amount of received light, the amount of dirt adhering to the light transmissive member of the transmission part 40 (column 41) is quantified (attachment amount quantification step). Further, the light receiving unit 30 receives the light of the irradiation unit 20 that has passed through the transmission unit 40, thereby measuring the light transmission amount of the transmission unit 40 when the branched water is flowing through the transmission unit 40 (light transmission). Quantity measuring step).

Next, in a state where the air is filled, the light receiving unit 30 receives the light of the irradiation unit 20 that has passed through the transmission unit 40, thereby measuring the light transmission amount of the transmission unit 40 in which the air is seen (light transmission). Quantity measuring step). Thereafter, the branched water is passed through the permeation unit 40 again.
In addition, when the transparent portion 40 is filled with fresh water, the light transmission amount of the transparent portion 40 is measured by the light receiving portion 30 in a state where the fresh water is filled. Is passed through the permeation section 40.
In this way, the amount of adhering matter quantification unit 60 quantifies the amount of adhering matter in the water passage 2 based on the amount of light received by the light receiving unit 30 (attachment amount quantifying step).

  Further, the adhering amount quantification unit 60 determines the branching based on the difference between the light transmission amount when the branched water is passed and the absorbance of the fresh water when blocking or the amount of light transmission when empty when measured by the light receiving unit 30. The turbidity of water can be determined. If the turbidity of the branched water can be measured, it can be used for estimating the amount of dirt adhered and the adhesion speed of the water passage 2.

  By photographing the light transmissive member and the reflective material of the transmission part 40 (column 41) with the photographing part 80 in synchronization with the dirt measurement, in addition to the degree of dirt quantified from the amount of received light, the sensory dirt through vision The degree can be evaluated.

  Thus, by performing the measurement work from the branch water blocking step to the adhering matter quantification step at regular time intervals, the tendency of dirt adhering to the permeation unit 40 can be grasped, and the effect of suppressing the drug fouling prevention means 70 can be obtained. In addition, it is possible to predict when cleaning is necessary by correlating with operational trouble data.

  In addition, the turbidity of the branched water is determined from the absorbance at the time of passing water measured in the presence of branch water and the absorbance of fresh water at the time of blocking and empty absorbance at the time of blocking measured in the absence of branch water. Calculate the amount of deposits adhering to the column in consideration of the influence of the turbidity of the calculated branch water when calculating the influence of the degree of turbidity and digitizing the amount of dirt adhering from the attenuation of the amount of transmitted light. Can do.

Further, by continuing the deposit quantification method continuously in batches, the adhesion tendency of dirt on the water passage can be grasped.
Due to the above-described action, the amount and frequency can be easily adjusted and controlled quickly with chemicals.

  As is clear from the above description, the adhering substance quantifying device 10 does not allow the branched water to pass through the permeation unit 40 when measuring the amount of transmitted light in the method for quantifying dirt in the water passage 2 by measuring the amount of transmitted light. Since the amount of light transmitted through the transmission part 40 can be measured without being affected by the turbidity of the branch water by performing the state, for example, when draining or with the branch water replaced with clean water, the amount of dirt adhered to the transmission part 40 Can be accurately quantified.

The deposit quantification apparatus 10 has been described as a discharge-type deposit quantification apparatus that discharges the branched water that has passed through the permeation unit 40, but the branch water that has passed through the permeation unit 40 again passes through the water flow path 2. It may be a circulation-type deposit quantification device that returns to the above. In this case, the fresh water used for the measurement can be returned to the mainstream after the measurement.
Moreover, although the number of the branch part 3, the column 41, and the stain | pollution | contamination prevention means 70 was demonstrated as multiple, all may be one.

  As shown in FIG. 3, the deposit quantification apparatus 10 includes a dirt prevention means 70 provided in the tributary part 3 upstream of the permeation part 40, and the permeation part 40 includes a plurality of columns arranged in parallel. 41 may be included. In this case, the branched water is branched into a plurality of branch waters by a plurality of flow portions 3 a formed downstream of the dirt preventing means 70, and the plurality of branch waters flow through the plurality of columns 41, respectively. Then, the antifouling agent injected from the antifouling agent injection unit 71 is stirred by the stirrer 72, and the stirred antifouling agent is injected into the plurality of columns 41.

In addition, as shown in FIG. 4, the shape of each column 41 may be a rectangular tube shape, and different materials may be combined on the four wall surfaces 42, 43, 44, 45. In this case, the four wall surfaces 42, 43, 44, 45 constituting the wall surface may be all different materials. Also, one set of two opposite wall surfaces 43, 45 is made of the same material, the other set of the other two wall surfaces 42, 44 is also made of the same material, and one set and the other set are different materials. It may be.
That is, when the shape of each column 41 is a square tube shape, there are two sets of opposing wall surfaces (wall surfaces 43, 45 and wall surfaces 42, 44). For example, one set (wall surfaces 43, 45) is made of acrylic resin, other The set (wall surfaces 42 and 44) is made of polyvinyl chloride, the irradiation unit 20 and the light receiving unit 30 are arranged for the wall surfaces 43 and 45, and another irradiation unit 20 and the light receiving unit 30 are arranged for the wall surfaces 42 and 44. By measuring the respective light transmission amounts, it is possible to evaluate the adhesion amount of dirt on different materials.

Also, one of the opposite wall surfaces (wall surfaces 43, 45) is a light transmissive member, and the other (wall surfaces 42, 44) is the same material as the actual water passage 2 such as stainless steel or resin rubber, or any light impermeability. The column 41 may be used as a material.
In this case, the amount of light is measured based on the light reflected on the wall of the light-impermeable material. That is, the light emitted from the light emitter 20a is first transmitted through the light-transmitting wall, then the transmitted light is reflected by hitting the light-impermeable wall such as stainless steel, and the reflected light is transmitted through the light-transmitting wall again. By measuring the amount of received light by receiving the received light with a light receiver, it is possible to evaluate the effect of dirt adhesion on the actual material.
Also, a combination of these measurement methods, that is, two types of sensors, reflection and transmission, can be mounted.

  As shown in FIG. 4, the irradiation unit 20 and the light receiving unit 30 may be combined, and a plurality of sets may be installed for one column 41. In this case, by using the average value of the plurality of dirt amounts respectively obtained from the plurality of light receiving units 30, it is possible to more accurately grasp the dirt adhesion.

  In addition, as shown in FIG. 5, the irradiation unit 20 and the light receiving unit 30 may be arranged on one wall 43 side of the transmission unit 40. In this case, the wall surface 45 on the other side of the transmission part 40 reflects the light from the irradiation part 20 by the light-impermeable member.

Example Simulated water was passed through a cell (material: acrylic, size diameter 25 mm × 200 mm) as a column.
Further, 330 g of waste corrugated paper was dispersed in 15 L of white water collected from a paper mill producing a paperboard liner, and beaten with a beater to prepare simulated water (CSF = 300 mL) having a pulp content of 2%.
While stirring at 800 rpm with an agitator with mixer blades attached to the prepared simulated water, 0.6% by mass of cationized starch and 1.25% by mass of sulfuric acid band, 0.36% by mass of paper strength enhancer, rosin emulsion size 0.15% by mass of the agent and 5% by mass of the filler were sequentially added. The addition interval of each chemical was 15 seconds.
Water was passed for 6 days, and the thickness of the attached dirt and the measured values of the amount of received light and turbidity were confirmed.

  In the measurement of the cell, the attenuation of the amount of laser light due to only the adhered dirt was measured by closing the water flow valve at the timing of measuring the adhered dirt amount. The measurement results are shown in FIGS. Here, in FIG. 6, the solid line indicates the amount of transmitted light, and the dotted line indicates the dirt thickness. In FIG. 7, a point shows the measured transmitted light quantity with respect to the dirt thickness, and a straight line shows a regression line of the measured transmitted light quantity with respect to the dirt thickness.

Reference Example The same operation as in the Example was performed except that the turbidity was measured in a state where water continuously passed. The measurement results are shown in FIGS. Here, in FIG. 8, the solid line indicates the amount of transmitted light, and the dotted line indicates the dirt thickness. In FIG. 9, a point indicates the measured transmitted light amount with respect to the dirt thickness, and a straight line indicates a regression line of the measured transmitted light quantity with respect to the dirt thickness.

As is apparent from FIGS. 6, 7, 8, and 9, the measurement by the example has a higher correlation with the amount of dirt adhesion than the measurement by the reference example, and an approximate line indicating the correlation is the adhesion amount. On the other hand, it was confirmed that the determination coefficient R ² (decision coefficient, which takes a value from 0 to 1, with 1 being the most accurate) indicating the degree of application is close to 1.
