Description

Chemical liquid cleaning deodorizer with automatic adjustment of chemical supply according to remote measurement of incoming odor gas concentration and cleaning liquid pH value }

The present invention relates to a chemical cleaning type deodorizer having an automatic chemical supply amount control function according to remote measurement of an inflow odor gas concentration and a cleaning liquid pH value, and more particularly, a gas inlet pipe connected to the gas distribution chamber of the chemical cleaning type deodorizer; Each withdrawal pipe is installed in each storage tank, but each withdrawal pipe is installed to extend to the inside of the control room installed separately from the chemical cleaning type deodorizer, and the gas concentration detection sensor installed at the entrance to the gas distribution room of the chemical cleaning type deodorizer Instead of removing the pH detection sensors installed in each storage tank, they are installed interchangeably in the sampling ports installed on the outlet pipes in the control room. At the same time, it is possible to minimize contamination by various foreign substances contained in the system, and at the same time to secure the reliability of the measured values detected through each sensor. Contaminated sensors can be easily replaced, and in particular, based on the accurate concentration (ppm) detection of the odor gas flowing into the gas distribution room and the accurate pH value detection of the chemical solutions, the system automatically controls the driving amount of the acid and alkali chemical injection pump. It has a function of automatically adjusting the amount of chemical supply according to the remote measurement of the concentration of the inflow odor gas and the pH value of the cleaning solution, which was invented to automatically inject the chemical solution with the optimum chemical compared to the inflow concentration of the actual odor gas into the acid cleaning unit and the alkali cleaning unit. It relates to a chemical cleaning type deodorizer.

In general, in places such as sewage treatment plants, excreta treatment plants, food treatment facilities, and livestock facilities, various organic or inorganic gases are generated and complex odors are generated. It has a characteristic that makes it difficult to process.

As a method of removing organic or inorganic odor gas based on these characteristics, a plurality of nozzles are installed in the deodorization tower, and water is sprayed on the gas containing the odor introduced into the deodorization tower to remove the odor (washing method) In addition, there is a method of arranging an adsorbent layer such as activated carbon, silica gel, and zelite in the deodorization tower to adsorb odor substances (activated carbon adsorption method), or a specific microbial layer instead of the adsorbent to prevent the microorganisms from odor There is a method to decompose the generated substances (microbe contact method), etc.

As such, the malodorous gas composed of the complex gas is usually cleaned by neutralization reaction by 'acid and alkali'. As a result, there was a limitation in the installation space due to the enlargement of the device, while it was not quick or limited in the inconvenience of construction and manufacturing and the deodorizing power of the complex gas.

Therefore, the present applicant has developed a two-liquid simultaneous washing and deodorizing tower that can solve the above problems and has been presented as Korean Patent No. 10-0820845.

Such a two-liquid simultaneous washing and deodorization tower is equipped with an acid and alkali washing tower at the same time, as well as each washing solution is circulated separately for washing, so that the device can be miniaturized, and it is fast and effective against bad odors, which are complex gases. In addition to securing excellent cleaning power, it was possible to obtain the effect of greatly improving the deodorization power through simultaneous neutralization of acid and alkali.

On the other hand, in most conventional chemical cleaning type deodorizing devices, the chemical concentration of the circulating chemical is automatically performed by a pH adjusting device, where the pH range to be adjusted has an upper limit and a lower limit set.

In the above, pH (pH value) is a numerical value indicating the degree of acidity or alkalinity of water, and is an index of hydrogen ion concentration. Water (aqueous solution) is partially ionized so that hydrogen ions (H ⁺ ) and hydroxide ions (OH ^- ) coexist. If the H ⁺ concentration and OH ^- concentration are the same, it is neutral; if there is more H ⁺ , it is acidic, OH ^- If it is too much, it becomes alkaline.

So, if the cation concentration is expressed in moles, the relational expression of [H ⁺ ]×[OH ^- ]=10-14 at 25°C is established. Therefore, when the value of [H ⁺ ] is determined, the value of [OH ^- ] is automatically determined, and only the value of [H ⁺ ] is needed to determine liquidity or the strength of acidity and alkalinity. So, to indicate the hydrogen ion concentration, the commercial logarithm of the reciprocal of the hydrogen ion concentration, that is, the hydrogen ion index, is displayed and the symbol of pH is used.

However, as a result of detecting the pH in the cleaning chemical storage tank through the pH detection sensor (pHC) without distinction between the method using gravity or a pump, the chemical injection method used in most of the conventional chemical cleaning deodorizers is the determined lower limit of the pH. If detected, open the chemical injection valve (in the case of the chemical liquid injection method by gravity) or drive the injection pump (in the case of the chemical liquid injection method by the pump) to start the chemical injection, and then close or inject the chemical injection valve at the upper pH limit The method of stopping the supply of the chemical solution by stopping the pump was adopted.

However, when injecting a chemical solution in the same manner as described above, a certain delay time is required in the operation mode to maintain a constant pH of the chemical solution in the chemical solution storage tank.

Excessive injection of the chemical solution not only increases the consumption of the chemical solution, but also provides a cause of failure of the device such as corrosion due to the high concentration, and has problems such as shortening the life of the device.

Accordingly, the present applicant developed "a chemical injection device for reducing chemicals and efficient operation in a chemical cleaning type deodorizing device" as a way to solve the above problems, and the applicant has developed Korean Patent Publication No. 10-1237725 (February 2013). 19) was presented.

“Chemical injection device for chemical saving and efficient operation in chemical cleaning deodorizer” presented above can simultaneously control complex odor components that react separately to acids and alkalis such as ammonia and hydrogen sulfide contained in exhaust gas. When it is judged that the pH value of the cleaning chemical storage tank has reached the lower limit in a chemical cleaning deodorization device that simultaneously uses a chemical (acid, alkali) cleaning solution configured to Inject the drug intermittently at a time interval set by the set timer for the drug injection time and the set timer for the pause time (for example, if the chemical solution circulation time of the drug reservoir is designed to be 3-8 minutes, inject the drug for 8-15 seconds and 3 -If the pH value does not reach the upper limit after stopping for 8 minutes, repeat the process of re-injecting and stopping). Because it can be applied, it is possible to prevent over-injection of drugs, so it is possible to save on drugs as well as perform efficient operation according to drug injection.

On the other hand, the concentration (ppm; parts per million; parts per million; parts per million) of the odor gas directly flowing into the gas distribution chamber provided in the main body of the chemical cleaning deodorizing device changes in real time, whereas the above-described chemical cleaning type deodorizing device saves chemicals. And the chemical injection device for efficient operation detects only the pH value in the cleaning liquid storage tank regardless of the concentration (ppm) of the odor gas directly flowing into the gas distribution chamber of the main body, and it is determined that the pH value of the cleaning liquid storage tank has reached the lower limit and injects the chemical liquid When operating the pump or opening the chemical injection valve to inject the chemical into the storage tank, the chemical injection time setting timer and the pause time setting timer intermittently inject the chemical at a set time interval. Although the concentration of the chemical is changed in real time, the efficient injection of the chemical is not performed accurately in real time, and the maintenance cost required due to the increase in the consumption of the chemical due to excessive injection of the chemical is also increased. The problem is still there.

In addition, due to the fact that a separate dilution device is not provided in each reservoir having a relatively large volume, the washing liquid stored in each reservoir when the chemical cleaning type deodorization device is operated has high fluidity (that is, the flowability of the fluid). Despite this lack), first and second pH detection sensors for detecting the pH value in each storage tank in real time and transmitting it to the control unit are installed in the first and second storage tanks, respectively.

Therefore, when the chemical cleaning deodorizing device of the above configuration is operated for a long period of time, the first and second pH detection sensors installed in each cleaning tank are easily corroded by the cleaning liquid itself in a stagnant state or are contained in the cleaning liquid. There is a risk that the pH detection sensor itself may be easily corroded or contaminated because the various foreign substances are fixed to the surface of the pH detection sensors. , there is a problem that the deodorization effect of odor gas is greatly reduced as well as corrosion or contaminated pH detection as well as the deodorization effect of odor gas is greatly reduced because automatic replenishment control according to the detection of the pH value is not performed properly. There were problems such as unnecessary maintenance cost due to frequent replacement of the sensor.

Accordingly, the present applicant developed "a chemical cleaning type deodorizer with automatic control function of chemical supply according to the inflow odor gas concentration and the pH measurement value of the cleaning liquid" as a way to solve the above problems It was proposed as -2092584 (March 18, 2020).

The chemical cleaning type deodorizer having the function of automatically adjusting the amount of chemical supply according to the concentration of the inflow odor gas and the pH measurement value of the cleaning liquid is largely divided into the main body and the acid cleaning unit, the alkali cleaning unit, the acid chemical injection pump, the alkaline chemical injection pump, and the first And in the known chemical cleaning type deodorizer having a second pH detection sensor and a control unit, a gas concentration detection sensor is further installed at the entrance to the gas distribution chamber, and the control unit detects in real time through the gas concentration detection sensor Calculating the reference pH values of the acid and alkali cleaning liquids required to remove (that is, removing the currently flowing malodorous gas) compared to the actual concentration of the incoming malodorous gas, respectively, and then detecting it through the first and second pH detection sensors After comparing the actual pH value of the acid and alkali cleaning solution in the first and second storage tanks to find the difference, the amount of chemical supplementation of acid or alkali component is automatically calculated for the tea value written in the form of a table in itself And, based on this, it is configured to automatically control the driving amount of the acid and alkali chemical injection pump.

In addition, the first and second pH detection sensors installed in the first and second storage tanks are respectively installed on the acid and alkali cleaning liquid transfer pipes in the rear part of the first and second circulation pumps, and the acid and chemical liquid injection pumps and First and second check valves are respectively installed on the acid chemical solution supply pipe and the alkali chemical solution supply pipe at the outlet side of the alkaline chemical solution injection pump, and the acid cleaning solution transfer pipe and the alkali at a portion coupled to the acid chemical solution supply pipe and the alkali chemical solution supply pipe, respectively The first and second line mixers are installed on the cleaning liquid transfer pipe.

Accordingly, it was possible to prevent and reduce the error of adding a lot of chemicals unnecessarily and the maintenance cost for the chemical cleaning deodorizer to some extent compared to the prior art.

However, in most conventional chemical cleaning deodorizers, as described above, a gas concentration detection sensor that detects the concentration of odor gas forcibly introduced into the gas distribution chamber through the exhaust fan in real time is disposed between the exhaust fan and the gas distribution chamber. In addition to being directly installed in the gas inlet pipe, the pH detection sensors for detecting the pH value of the cleaning solutions in each storage tank in real time are installed directly in the storage tank.

However, when the gas concentration detection sensor is installed directly on the gas inlet pipe as described above, the state of continuous contact with the odor gas containing a large amount of moisture and fine dust is maintained while the chemical cleaning type deodorizer is operating. Therefore, within a short period of time, various fine dust adheres to and adheres to the surface of the gas concentration detection sensor, as well as easily corroded due to these, and the reliability according to the concentration detection of the odor gas is rapidly reduced (that is, the error due to the detection of the concentration of the odor gas is reduced. ), and the reliability of the chemical solution replenishment, which is automatically controlled in response to the detection value of the odor gas concentration, is also greatly reduced, so that the deodorizing effect of the odor gas is greatly reduced.

In addition, when the pH detection sensors are also installed directly in the storage tank as described above, as described above, the pH detection sensors are easily corroded by the cleaning liquid itself that is almost stagnant in the storage tank or are contained in the cleaning liquid. Various foreign substances and suspended matter are attached to the surface of the pH detection sensors and then become fixed, and there is a risk that the pH detection sensor itself may be easily corroded or contaminated. There is a problem that the deodorizing effect of the odor gas is greatly reduced because the automatic replenishment control of the chemical liquid according to the detection is not performed properly, and there are problems such as unnecessarily high maintenance cost.

Of course, in some chemical cleaning deodorizers, as described above, the pH detection sensors are installed on the acid and alkali cleaning liquid transfer pipes at the rear of the circulation pump, respectively, and are partially washed by the transfer pressure of the cleaning liquids, but in this case also Since the pH detection sensors maintain a form of continuous contact with the contaminated cleaning solution being transported through the inside of the cleaning solution transfer pipe, if it exceeds a certain amount of time, eventually, the cleaning solution will corrode, and various foreign substances contained in the cleaning solution will adhere and stick to the surface. As a result, the above-described problem appears as it is in a short time.

Therefore, the gas concentration detection sensor or the pH detection sensor must not only be inspected frequently, but must be separated (usually 1 to 2 days) and re-installed through a procedure such as washing or replaced with a new one. Reliability for concentration and pH values can be guaranteed.

However, most chemical cleaning type deodorizers not only have a configuration to deodorize a large amount of odor gas in a short time, but also have a very large volume, so they have to be installed outdoors, and also the gas concentration detection sensor or pH The detection sensors also have an installed configuration of a gas inlet pipe provided at a relatively high position and a storage tank or a cleaning solution transport pipe having a relatively high height.

Accordingly, the manager of the chemical cleaning deodorizer is equipped with various tools and equipment for inspection, and is installed outdoors using a ladder in the state that the operation of the chemical cleaning type deodorizer is blocked almost every day regardless of the weather. After going up directly to the gas inlet pipe and the upper surface of the storage tank or the cleaning solution transfer pipe of the chemical cleaning deodorizer, the gas concentration detection sensor and the pH detection sensor are separated and checked or cleaned, and then reinstalled or new sensors There is the inconvenience of having to replace and install it.

In addition, in a situation in which such inspection, cleaning, or replacement process is repeated, there is a very high risk of a safety accident due to the negligence of the manager, etc. Since the operation of the chemical cleaning type deodorizer is blocked, there is a problem such as leading to a decrease in the amount of deodorization processing for various odor gases.

Therefore, it is possible to minimize the contact time between the pH detection sensors including the gas concentration detection sensor and the odor gas and the cleaning liquid, thereby minimizing the attachment of various foreign substances contained in the odor gas and the cleaning liquid to the surface of each sensor. The precision and reliability of detecting the concentration of the odor gas and the pH value of the cleaning solution can be increased, and the time and cost can be greatly reduced while ensuring the convenience and safety of checking, cleaning, and replacing each sensor and filter. There is a need for a method to prevent a decrease in the amount of deodorization processing for various odor gases by enabling inspection, cleaning and replacement of each sensor and filter while continuously driving the chemical cleaning type deodorizer.

At this time, the control unit calculates a reference pH value of each cleaning solution required to remove the odor gas compared to the actual concentration of the odor gas currently flowing into the gas distribution room, which is detected through the gas concentration detection sensor installed in the odor gas sampling port in the control room. Then, the difference is obtained by comparing the current pH values of the cleaning solutions in the respective storage tanks detected through the first and second pH detection sensors installed in the first and second cleaning liquid sampling ports, respectively, and then the difference is obtained in the form of a table in the control unit. It is characterized in that it automatically calculates the amount of chemical replenishment of acid or alkali component with respect to the input difference value, and automatically controls the driving amount of the acid and alkali chemical injection pump based on this.

In addition, at a predetermined time in the control unit, the first to third electromagnetic valves are opened, the sampling fan and the first and second cleaning liquid sampling pumps are operated, respectively, through the gas concentration detection sensor and the first and second pH detection sensors. When measuring the gas concentration of the odor gas and the pH value of the acid cleaning solution and the alkaline cleaning solution, the odor gas remaining after flowing into the extraction pipe for taking out the odor gas and the first and second cleaning liquid samples during sampling and measurement Alternatively, after a delay time corresponding to the length of each withdrawal pipe has elapsed so that the cleaning liquid is completely discharged to the outside, the control unit measures the concentration of the odor gas and the pH value of the cleaning liquid through each sensor, and automatically injects the measured values It is characterized in that it is used as data.

That is, the second collection pipe 350 and the second storage tank 310 are connected by a pipe and a valve to promote a circulation system.

In addition, the acid chemical injection pump 410 operates in response to the output signal of the control unit 600 in a state installed between the acid medicine container 400 and the first storage tank 210, and the first storage tank 210 It performs a function of automatically replenishing the acid chemical solution (medicine) stock solution stored in the acid chemical solution container 400 to the acid washing solution accommodated therein.

At this time, the installation position of the acid chemical liquid injection pump 410 is not limited to the above, and although not shown in FIG. 1 , on the acid chemical liquid supply pipe separately installed between the cleaning liquid transfer pipe 230a and the acid chemical liquid container 400 . In the state of being installed in the first storage tank 210, it is operated in response to the output signal of the control unit 600, and the acid chemical solution stock solution stored in the acid chemical solution container 400 is transferred to the pickling solution transfer pipe 230a, not the first storage tank 210. Through a method of directly supplying the inside, the pickling solution being transported into the pickling solution transfer pipe 230a may be automatically supplemented directly.

In addition, the alkaline chemical liquid injection pump 510 is installed between the alkaline chemical liquid container 500 and the second storage tank 310 and is operated in response to the output signal of the control unit 600 , and the second storage tank 310 . It performs a function of automatically replenishing the alkali chemical solution (medicine) stock solution stored in the alkali chemical solution container 500 to the alkali cleaning solution accommodated therein.

It performs the overall control function of the chemical cleaning type deodorizer such as driving.

Meanwhile, in an embodiment of the present invention, as shown in FIGS. 1 and 2 , the gas inlet pipe 150 and the first and second gas inlet pipes 150 installed between the gas distribution chamber 160 and the exhaust fan 140 of the main body 100 . A withdrawal pipe 910 for taking out samples of the odor gas and the first and second cleaning liquid, which extends and withdraws a portion of the odor gas and the cleaning liquid from the storage tanks 210 and 310 to the control room 1000 installed separately from the main body 100, respectively. ) (920) and (930) have a configuration in which each is further installed.

At this time, the control room 1000 has a housing shape having a very small volume compared to the body 100 having a relatively large volume, and the control unit 600 as well as each component to be described later can be installed inside the main body. Formed separately from 100, it can be installed outside (outdoor) or in a building at a location away from the main body 100 by a certain distance. Of course, it has the advantages of very good operability and very convenient management.

Therefore, inspection, washing, and replacement of each sensor and filter described later can be easily carried out in the control room 1000 separately installed with a chemical cleaning type deodorizer having a relatively large volume, so that the inspection, washing and replacement of each sensor and filter and Not only can the convenience and safety of replacement be ensured, but time and cost can also be significantly reduced. Also, while the chemical cleaning deodorizer is continuously operated, each sensor and filter can be checked, cleaned and replaced, so it is effective against various odorous gases. It is possible to significantly increase the amount of deodorization treatment.

In addition, since the extraction pipe 910 for taking out the odor gas sample samples only a part of the odor gas flowing into the gas distribution chamber 160 and extends it toward the control chamber 1000, it has a relatively large diameter (for example, φ 1,000). It is sufficient if the gas inlet pipe 150 having a tube body having a relatively small diameter (for example, φ 50) is sufficient, and the first and second extraction pipes 920 and 930 for taking out the first and second cleaning liquid samples are the first and Since only a portion of the cleaning liquid in the second storage tanks 210 and 310 is sampled and extended to the control chamber 1000 side, a tube having a relatively small diameter (for example, φ 30-50) is sufficient, and the length is the gas The inflow pipe 150 may be determined in consideration of the distance between the first and second storage tanks 210 and 310 and the control room 1000 .

In addition, in the present invention, a first electromagnetic valve 911, a sampling fan 912, and a filter 913 for removing foreign substances in the odor gas on the extraction pipe 910 for taking out the odor gas sample introduced into the control room 1000. And a malodorous gas sampling port 914 is installed, and the second and third electromagnetic valves 921 (921) ( 931), first and second cleaning liquid sampling pumps 922 and 932, filters 923 and 933 for removing foreign matter in the first and second cleaning liquid, and first and second cleaning liquid sampling ports 924 and 934 has a configuration in which each is installed.

At this time, the sampling fan 912 including the first to third electromagnetic valves 911, 921, and 931 and the first and second cleaning liquid sampling pumps 922 and 932 are deodorized with a chemical cleaning liquid to which the present invention is applied. During the period in which the device is operated, it is automatically opened and driven by the control unit 600 for a set driving time at a time interval determined by the administrator, and a part of the odor gas flowing into the gas distribution chamber 160, the first and second A portion of the cleaning liquid in the storage tanks 210 and 310 is automatically supplied to the extraction pipes 910, 920, and 930 for taking out the odor gas and the first and second cleaning liquid samples, respectively.

Here, the predetermined time intervals for the first to third electromagnetic valves 911, 921, 931, the sampling fan 912, and the first and second cleaning liquid sampling pumps 922 and 932 set by the administrator or the like are particularly It cannot be limited and can be arbitrarily changed automatically or manually depending on the type and concentration of the odor gas to be deodorized, and can be set, for example, between 10 and 30 minutes, and the set driving time cannot be particularly limited. It is set automatically or manually in consideration of the length of the outgoing pipes, and can be set, for example, between 1 and 5 minutes.

Therefore, it is possible to minimize the contact time between the first and second pH detection sensors 710 and 720 including the gas concentration detection sensor 800 and the odor gas and the cleaning liquid, so that each sensor can detect the odor gas or each cleaning liquid. Contamination by various foreign substances contained in the sensor can be minimized and, at the same time, the precision and reliability of the measured values detected through each sensor can be greatly increased.

In addition, since the sampling fan 912 has a very small exhaust capacity compared to the exhaust capacity of the exhaust fan 140, it is drawn and supplied from the gas inlet pipe 150 to the odor gas sample extraction pipe 910 side. The amount of the malodorous gas to be given is a very small amount compared to the total amount flowing into the gas distribution chamber 160 .

In addition, since the pumping capacities of the first and second cleaning liquid sampling pumps 922 and 932 are also very small compared to the pumping capacities of the first and second circulation pumps 220 and 320, the first and second The amount of cleaning liquids drawn out from the second storage tank 310 to the withdrawal pipes 920 and 930 for taking out the first and second cleaning liquid samples is also the total amount of cleaning liquid in the first and second storage tanks 210 and 310. Since it is a very small amount compared to the capacity, it does not interfere with the deodorization operation of the chemical cleaning type deodorizer or damage due to the final discharge to the outside through the withdrawal pipe, respectively.

In addition, the filters 923 and 933 for removing foreign substances in the first and second cleaning liquid including the filter 913 for removing foreign substances in the malodorous gas include generally well-known air filters for automobiles and the like.

The filter 913 for removing foreign substances in the malodorous gas is included in the sampling malodorous gas that is drawn out and supplied by the sampling fan 912 in a state in which it is replaceably installed on the withdrawal pipe 910 for taking out the malodorous gas sample. In order to prevent the gas concentration detection sensor 800 from being polluted by various foreign substances including dust, thereby reducing detection performance, and the like, a function of filtering foreign substances is performed.

In addition, the filters 923 and 933 for removing foreign substances in the first and second cleaning liquids are installed in the first and second cleaning liquid sample extraction pipes 920 and 930 to be replaced respectively on the first and second cleaning liquids. First and second pH detection by various foreign substances contained in the sampling acid cleaning solution (first cleaning solution) and alkaline cleaning solution (second cleaning solution) drawn out and supplied by the first and second cleaning liquid sampling pumps 922 and 932 In order to prevent the sensors 710 and 720 from being contaminated and the detection performance from being deteriorated, a function of filtering the foreign substances is performed.

Therefore, it is possible to minimize the contamination of the first and second pH detection sensors 710 and 720 including the gas concentration detection sensor 800 by odor gas or various foreign substances contained in each cleaning liquid. The precision and reliability of the measured values detected by each sensor can be further improved.

On the other hand, in the drawing, the first and second filters 923 and 933 for removing foreign substances in the cleaning liquid including the filter 913 for removing foreign substances in the odor gas are respectively included in the first and first cleaning liquids including the sampling fan 912 . 2 Although the example provided in the rear end of the cleaning liquid sampling pumps 922 and 932 is illustrated, the present invention is not limited thereto.

For example, although not shown, the first and second filters 923 and 933 for removing foreign substances in the first and second cleaning liquids including the filter 913 for removing foreign substances in the malodorous gas are included in the second cleaning liquid including the sampling fan 912, respectively. When the first and second cleaning liquid sampling pumps 922 and 932 are installed at the front end, various foreign substances contained in the first and second cleaning liquids including malodorous gas are removed from the first and second cleaning liquids including the sampling fan 912. 2 It can already be filtered at the front end of the cleaning liquid sampling pumps 922 and 932.

Accordingly, the first and second cleaning liquid sampling pumps 922 and 932 including the sampling fan 912 also include the first and second pH detection sensors 710 and 720 including the gas concentration detection sensor 800 . Likewise, it is possible to prevent contamination by various foreign substances in advance.

In addition, the first and second cleaning liquid sampling ports 924 and 934 including the odor gas sampling port 914 are drawn out pipes 910, 920, 930 for taking out the odor gas and the first and second cleaning liquid samples. ) has a cylindrical or rectangular cylindrical shape having an inlet and an outlet through which the odor gas and the cleaning liquid are introduced and discharged, and a withdrawal pipe for taking out samples of the odor gas and the first and second cleaning liquids in the control room 1000 It has a form coupled in series on (910, 920, 930).

The first and second cleaning liquid sampling ports 924 and 934 including the odor gas sampling port 914 are the first and second pH detection sensors 710 including the gas concentration detection sensor 800 . At the same time as performing the function of allowing the 720 to be interchangeably coupled, the odor gas and the odor gas flowing through the extraction pipes 910, 920, and 930 for extracting the first and second cleaning liquid samples are included. The first and second cleaning liquids are temporarily stagnant, and the concentrations of odor gas and the first and second cleaning liquids in the first and second pH detection sensors 710 and 720 including the gas concentration detection sensor 800, respectively. It functions to accurately measure the pH value of

Therefore, when the manager wants to check, clean, and replace the gas concentration detection sensor 800 or the first and second pH detection sensors 710 and 720, chemical liquid cleaning type deodorization having a relatively large volume After entering the control room 1000 manufactured separately and installed outdoors or indoors, each sensor installed in the odor gas sampling port 914 or the first and second cleaning liquid sampling ports 924 and 934 As it can be easily carried out, it is possible not only to secure the convenience and safety of inspection, cleaning and replacement of each sensor and filter, but also to significantly reduce time and cost.

In addition, in the present invention, as described above, the control unit 600 opens the first to third electromagnetic valves 911, 921, and 931 at a predetermined time interval and for a predetermined driving time, and the sampling fan 912 and The first and second cleaning liquid sampling pumps 922 and 932 are operated, and the gas concentration and acid of the malodorous gas through the gas concentration detection sensor 800 and the first and second pH detection sensors 710 and 720, respectively. After measuring the pH values of the cleaning liquid and the alkaline cleaning liquid, the acid chemical liquid injection pump 410 connected to the first storage tank 210 and the alkaline chemical liquid injection pump 510 connected to the second storage tank 310 corresponding to the values The driving amount was automatically controlled.

That is, in the present invention, the control unit 600 causes the gas distribution chamber 160 to be detected through the gas concentration detection sensor 800 installed in the odor gas sampling port 914 in the control room 1000. First and second pH detection sensors installed in the first and second cleaning liquid sampling ports 924 and 934, respectively, after calculating the reference pH value of each cleaning liquid required to remove it compared to the actual concentration of the odor gas ( After comparing the pH value of the current washing liquids in each storage tank detected through 710 and 720 to obtain the difference, the amount of chemical supplementation of acid or alkali component for the tea value written in the table form in itself is automatically calculated It was calculated, and based on this, the driving amount of the acid and alkali chemical injection pumps 410 and 510 could be automatically controlled.

Therefore, it is possible to automatically inject the optimum chemical compared to the actual inflow concentration of the odor gas into the cleaning chamber in the first and second storage tanks 310, thereby fundamentally preventing the excessive injection of the chemical, so that a large amount of the chemical is added unnecessarily. Not only can the errors caused by the drug be greatly prevented, but also, the maintenance cost of the chemical cleaning deodorizer can be greatly reduced through efficient operation according to the chemical replenishment, and the chemical solution is economical, stable, and continuously deodorizes the odor continuously. It is possible to significantly increase the commercial properties of the cleaning deodorizer itself and the reliability according to deodorization.

In the present invention, the control unit 600 opens the first to third electromagnetic valves 911, 921, and 931 at a predetermined time, and the sampling fan 912 and the first and second cleaning liquid sampling pumps ( The gas concentration detection sensor 800 which operates 922 and 932 and is detachably installed in the odor gas sampling port 914 and the first and second cleaning liquid sampling ports 924 and 934, respectively; When measuring the gas concentration of the malodorous gas and the pH values of the acid cleaning solution and the alkali cleaning solution through the first and second pH detection sensors 710 and 720, respectively, from the time when the sampling malodorous gas, the acid cleaning solution, and the alkaline cleaning solution start flowing After a certain time delay, each measurement was made.

That is, in the present invention, the concentrations and pH values of the sampling malodorous gas flowing into the malodorous gas sampling port 914 and the first and second cleaning liquid sampling ports 924 and 934, and the acid cleaning liquid and the alkaline cleaning liquid are respectively described above. When measuring through the gas concentration detection sensor 800 and the first and second pH detection sensors 710 and 720, when sampling and measuring before, the odor gas and the first and second cleaning liquid samples are taken out After the odor gas or cleaning liquid remaining after the pre-introduction into the withdrawal pipes 910, 920, and 930 is completely discharged to the outside, the odor gas and the agent currently actually flowing into the gas distribution chamber 160 are In order to accurately measure the pH value of each cleaning solution supplied to the acid cleaning unit 200 and the alkali cleaning unit 300 in the first and second storage tanks 210 and 310, the length of each withdrawal pipe After a corresponding delay time has elapsed, the control unit 600 causes the concentration of the odor gas and the cleaning solutions to The pH value was measured and the measured value was used as data for automatic drug injection.

Accordingly, it is possible to more accurately measure the concentration of the odor gas currently flowing into the gas distribution chamber 160 in real time and the pH value of each cleaning solution currently being supplied to the acid cleaning unit 200 and the alkali cleaning unit 300 . The amount of chemical supply is accurately automatically adjusted in response to the concentration of the odor gas detected by the gas concentration detection sensor 800 and the accurate measurement value of the pH of the cleaning solutions detected by the first and second pH detection sensors 710 and 720 Since it can be adjusted, it is possible to significantly increase the efficiency and reliability of the automatic supply of chemicals added in response to the current concentration of odor gas and the pH value of cleaning solutions.

Meanwhile, the description so far has been described above on the extraction pipe 910 for taking out the odor gas sample introduced into the control room 1000, the first electromagnetic valve 911, the sampling fan 912, and a filter for removing foreign substances in the odor gas ( 913) and the odor gas sampling port 914 are installed one by one, and the second and second 3 Solenoid valves 921 and 931, first and second cleaning liquid sampling pumps 922 and 932, filters 923 and 933 for removing foreign matter in the first and second cleaning liquid, and first and second cleaning liquid sampling ports Although the description has been focused on an example in which only one (924) and one (934) is installed, the present invention is not limited thereto, and other various examples may be applied.

The gas concentration detection sensor 800 or the first and second pH detection sensors 710 and 720 are respectively replaceably provided on the withdrawal pipes branched to and connected in parallel to each other. A shut-off valve 940 that can be manually or automatically opened and closed separately from each other for each branched withdrawal pipe including the port 914 or the first and second cleaning liquid sampling ports 924 and 934 is installed. include that

At this time, the shut-off valve 940 includes an electromagnetic valve that can be opened and closed sequentially in sequence at a predetermined period by the control unit 600, and includes any one of manual valves that an administrator can arbitrarily open and close as needed. .

In addition, the filters 923 and 933 for removing foreign substances in the first and second cleaning liquid including the filter 913 for removing foreign substances in the malodorous gas for filtering various foreign substances contained in the odor gas or the cleaning liquid, as shown in FIG.

In addition, in the present invention, the inside of the first and second cleaning liquid sampling ports 924 and 934 including the odor gas sampling port 914 is an electronic valve for time constant supply control that is automatically opened and closed by the control unit 600 . A sensor having a 950 and a time constant supply pipe 960 for port cleaning are further installed, and at the bottom of each sampling port, in order to automatically discharge the time constant polluted due to the washing of each sensor to the outside, by the control unit 600 A drain pipe 980 provided with an electromagnetic valve 970 for drain whose opening and closing is controlled was further installed.

At this time, the control unit 600 opens the first to third electromagnetic valves 911, 921, and 931 at a predetermined time interval, and the sampling fan 912 and the first and second cleaning liquid sampling pumps 922 ) (932) to pass a portion of the odor gas and each cleaning solution through the withdrawal pipes, and the gas concentration detection sensor 800 and the first and second pH detection sensors 710 provided in each sampling port ( After measuring the concentration of the odor gas and the pH value of the cleaning solutions through 720), the first to third electromagnetic valves 911, 921, and 931 are closed after a predetermined driving time has elapsed, and the sampling fan 912 and After blocking the driving of the first and second cleaning liquid sampling pumps 922 and 932, the sensor and port are cleaned by opening and closing the electromagnetic valve 950 for controlling the time constant supply for a predetermined time (for example, 1 to 2 minutes). The inside of each sampling port as well as each sensor installed therein are automatically cleaned by the water pressure of the time constant that is strongly injected or injected into each sampling port through the time constant supply pipe 960 .

The timing of opening the electronic valve 950 for controlling the time constant supply is measured by the gas concentration detection sensor 800 and the first and second pH detection sensors 710 and 720 to measure the concentration of the odor gas and the pH value of the cleaning solutions. Immediately after completion of the measurement, or after a certain amount of time sufficient to allow some residual harmful gas or cleaning liquid remaining in each sampling port to be automatically discharged to the outside of the control room 1000 through the withdrawal pipe, or 1 day It can be done once in

When the electronic valve 950 for time constant supply control is opened immediately after the measurement of the concentration of the odor gas and the pH value of the cleaning solutions is completed, the cleaning efficiency for various foreign substances adhering to the surface of each sensor is good, but residual in each sampling port Since there is a risk of environmental pollution by being discharged to the outside together with the contaminated time constant, some residual harmful gas or cleaning liquid remaining in each sampling port after the measurement is completed is removed from the control room (1000) through the withdrawal pipe. ), it is desirable to carry out once a day or after a certain amount of time has elapsed so that it can be automatically discharged to the outside.

Of course, in cleaning each sensor using the time constant supplied from the water supply pipe, if only the cleaning efficiency of the above two preferred examples is considered, the measurement is completed and some residual harmful gases or cleaning liquids remaining in each sampling port are removed through the withdrawal pipe. It is better to carry out after a certain period of time sufficient to be automatically discharged to the outside of the control room 1000 has elapsed, but in this case, there is a risk of wasting time constant unnecessarily. After being attached to the surface of each sensor, there is a fear that some may stick, so it is lower than the above-mentioned method in terms of cleaning efficiency, but it is more advantageous in terms of preventing unnecessary waste of time constant, so it is more advantageous in terms of on-site conditions (i.e., concentration of odor gas, etc.) ) to determine the timing of opening the electromagnetic valve 950 for controlling the time constant supply.

In addition, the electromagnetic valve for drain 970 provided on the drain pipe 980 at the bottom of each sampling port is maintained in a normally closed state by the control unit 600, and the control unit 600 automatically controls various sensors. When the time constant supply control valve 950 is opened for washing, it is opened at the same time or after a certain time delay, and after a predetermined cleaning time has elapsed, the time constant supply control valve 950 is closed, and then in each sampling port. It is preferable to close the remaining contaminated time constant after a sufficient time has elapsed so that all of the remaining contaminated time constant is automatically discharged through the drain pipe 980 to an externally provided drain of the control room 100 .

As described above, in the present invention, after the concentration of the odor gas and the pH value of the cleaning liquids are measured in the sampling port provided on each withdrawal pipe, the time constant supplied from the water supply pipe is strongly injected or sprayed into each sampling port. Since the sensors installed inside the sampling port of Detection errors that occur can be reduced to a minimum.

Therefore, it is possible to significantly improve the deodorization effect of the odor gas as well as the effect on the automatic control function of the chemical supply according to the concentration of the incoming malodorous gas and the pH measurement value of the cleaning liquid, and in particular, the lifespan of the sensors can be greatly extended. It is possible to significantly reduce the maintenance cost of the formal deodorizer itself.
