The present invention relates to a chemical cleaning deodorizer having an automatic replacement function of a contaminated chemical, and more particularly, a one-stage chemical cleaning deodorizer equipped with only one cleaning unit or a first-stage cleaning unit and a two-stage cleaning unit in the main body. One or two used to continuously circulate and supply various cleaning chemicals (for example, acid cleaning solution and alkali cleaning solution) in the installed two-stage chemical cleaning and deodorizing machine (hereinafter referred to as “chemical cleaning and deodorizing machine”) A separate circulating chemical cleaning tank is installed outside the chemical storage tank, and in normal operation of the chemical cleaning and deodorizing machine, the chemical liquid that passes through the cleaning unit and circulated is passed through the circulating chemical cleaning tank, and various sludges contained in the circulating chemical liquid are passed through the cleaning tank. It is deposited on the floor using its own weight, and floating substances such as salt by-products are floated on the surface of the circulating chemical. Occurs in the process of removing odor gas using cleaning chemicals through repeated cleaning and draining operations and replenishing operation of a new chemical solution having a set hydrogen ion concentration (pH) value in the circulating chemical cleaning tank and then returning to normal operation. Solubility of salt in the chemical solution (i.e., cleaning solution) returned to the chemical storage tank after completion of the treatment, as well as the frequent replacement of the chemical solution due to various sediments settling in the form of sludge (i.e., to extend the replacement cycle of the entire chemical solution) In addition, it is possible to significantly reduce the cost due to frequent replacement of the chemical solution, and greatly increase the water-soluble odor gas removal efficiency using the chemical solution by reducing the solubility of the salt by-product, and the occlusion of the chemical cleaning deodorizer by the salt by-product It relates to a chemical cleaning and deodorizing machine having an automatic replacement function of a contaminated chemical, which is invented to significantly improve the deodorizing performance of the chemical cleaning and deodorizing machine itself by preventing the increase in turbidity of the chemical due to deposits as well as prevention.

In general, in places such as sewage treatment plants, excreta treatment plants, food treatment facilities, livestock facilities, etc., various organic or inorganic gases are generated and a complex odor is produced. With a single chemical cleaning solution such as an oxidizing agent (sodium hypochlorite, etc.), which has a slow reaction rate compared to the reaction, effective treatment of odor gas is difficult.

As a method of removing malodorous gas of complex nature based on these characteristics, a method in which a plurality of nozzles are installed in a deodorization tower, and the gas containing malodor introduced into the deodorization tower from this is contacted with water to remove the malodor (water washing method) ), and a method of arranging an adsorbent layer such as activated carbon, silica gel, and zelite in the deodorizing tower to adsorb odor substances (adsorption method) There is a method to decompose them (microbe contact method), etc.

As such, the malodorous gas composed of a complex gas is usually purified by neutralizing reaction with an 'acid and alkali' chemical solution, and such a conventional deodorizing tower has a slow reaction rate and low efficiency, but an oxidizing agent that reacts complexly (sodium hypochlorite, etc.) It consists of a single deodorizing tower using Due to the large size, there was a problem that the installation space and installation cost were excessive.

In order to improve this problem, Korean Patent Registration No. 10-0820845 (title of the invention: two-component simultaneous washing and deodorizing tower) has been disclosed, which the present applicant applied for and registered. By equipping the cleaning tower as an integrated deodorizing tower, each cleaning liquid circulates separately to clean the complex gas, thereby reducing the size of the device. It has the effect of being formed so that the deodorization power is improved by the simultaneous neutralization reaction of acid and alkali of course.

The two-liquid simultaneous cleaning and deodorization tower uses a jet nozzle when cleaning the composite gas, wherein the jet nozzle corresponds to a gas distribution room having a plurality of supply pipes, and the supply pipe of the gas distribution room, but when combined, the outer end and a set interval It is formed so as to be covered with a supply hole, and is composed of an injection cap formed so that the odor gas is injected into the liquid through the supply hole onto the bubbles, and the jet nozzles are arranged in a plurality of uniformly distributed inside the body.

Accordingly, even if a plurality of the jet nozzles are evenly distributed and disposed inside the body, the opening ratio cannot be increased on arrangement, resulting in a large pressure loss.

In addition, there is a problem in that it is difficult to make fine bubbles because the width of the injection port of the unit nozzle is large in structure, and the cleaning efficiency is lowered because the bubbles injected into the water are large.

In addition, the two-solution simultaneous washing and deodorization tower is provided with a collecting ditch that is formed to collect the acid washing liquid passing through the pack bed and falling to the lower part from the lower part of the pack bed. Accompanying with the gas flow, it is carried over to the pickling unit, which is a two-stage washing unit, and is mixed with the pickling solution collected in the collecting ditch to neutralize the pickling solution. There was a problem.

Accordingly, the present applicant has also applied for a "two-liquid simultaneous washing and deodorizing tower" as a way to solve the above problems and has presented Korean Patent Registration No. 10-1203420.

As shown in FIG. 1, the two-liquid simultaneous cleaning and deodorization tower presented in the Korean Patent Registration No. 10-1203420 collects mist of the cleaning solution contained in the air that has been cleaned and purified above the hollow body. A purification gas outlet 12 for discharging the purified air in which the part 11 and the cleaning liquid mist is collected is provided, and a gas distribution chamber 13 and an exhaust fan provided on one outside of the gas distribution chamber 13 are provided at the bottom ( a body 10 provided with a gas inlet pipe 15 through which odor gas is introduced from 14);

A first cleaning liquid storage tank 21 provided on the bottom surface of the main body 10 and accommodating the first cleaning liquid, and the first cleaning liquid provided at one side of the first cleaning liquid storage tank 21 and accommodated in the main body 10 are stored inside the main body 10 a first cleaning solution circulation pump 22 for transferring to (23), the malodorous gas is provided between the gas distribution chamber 13 and the first cleaning liquid supply pipe 23 and is supplied by the first supply pipe 23 and injects the malodorous gas into the alkaline cleaning liquid maintained at a constant water level. The fine jet nozzle cleaning unit 24 that simultaneously removes dust contained in the malodorous gas while purifying the odor gas by cleaning a first-stage cleaning unit 20 provided with a first cleaning liquid level adjusting unit 25 for adjusting and circulating and transferring to the first cleaning liquid storage tank 21;

A second cleaning liquid storage tank 31 provided adjacent to the first cleaning liquid storage tank 21 on the bottom surface of the main body 10 and accommodating the second cleaning liquid, and the second cleaning liquid storage tank 31 provided on one side A second cleaning liquid circulation pump 32 for transferring the received second cleaning liquid to the inside of the main body 10, and a second cleaning liquid transferred by the second cleaning liquid circulation pump 32 downward in the main body 10 a second cleaning liquid injection pipe 33 having a plurality of supply holes to The cleaning pack-bad part 34, the odor gas provided under the second cleaning pack-bad part 34 and cleaned in the first-stage cleaning part 20 is moved to the second cleaning pack-bad part 34. A second cleaning liquid collecting unit 35 that collects the second cleaning liquid that is sprayed by the second cleaning liquid injection pipe 33, passes through the second cleaning pack bed 34 and falls to the bottom, and the second cleaning liquid is collected and a two-stage cleaning unit 30 provided on one side of the unit 35 and provided with a second cleaning liquid circulation unit 36 for transferring the collected second cleaning liquid to the second cleaning liquid storage tank 31 .

However, in the two-liquid simultaneous washing and deodorization tower presented in Korean Patent Registration Nos. 10-1203420 including the above-mentioned Korean Patent Registration No. 10-0820845, the first-stage washing unit 20 and the second-stage washing unit 30 are the upper parts. A first cleaning liquid storage tank 21 as a storage tank at the bottom of the main body 10 as well as having a form integrally installed in the vertical direction inside the body 10 having a cylindrical tower shape and having a purification gas outlet 12 in the ) and the second cleaning liquid storage tank 31 are integrally provided.

On the other hand, in all conventional chemical cleaning and deodorizing machines, when the odor gas and each cleaning liquid come into contact with each other and a chemical reaction occurs, foam-type salt by-products and various precipitates are generated by neutralization and oxidation, and these salts and precipitates are stable fine solids. It is dissolved in the cleaning solution produced by the furnace and contaminates the cleaning solution.

Wherein as salt by-products also are including (CH _{3) 2} SNa generated during neutralization of Na ₂ S and methyl mer taptan and sodium hydroxide generated during the neutralization reaction of hydrogen sulfide and sodium hydroxide, ammonia and sodium hypochlorite, tri methyl It refers to stabilized compounds such as 3NaCl, NaCl, and 5NaCl, which are generated during the oxidation reaction between amine and sodium hypochlorite, and between methyl disulfide and sodium hypochlorite, respectively.

In this way, the initial salt by-products generated in the deodorization process of the odor gas using the cleaning liquid are generated in the form of bubbles, and various sediments sink to the bottom of the storage tank. These bubbles are removed by the shower system inside the various cleaning liquid storage tanks. The salt contained in the removed foam is rapidly dissolved in the cleaning liquid, which is a chemical, and causes contamination that contaminates the cleaning liquid.

However, in the prior art, the initial foam, salt by-products and deposits generated in the deodorization process of the odor gas using the cleaning liquid could not be removed, so the entire amount of the cleaning liquid had to be replaced at regular intervals. There is a problem in that the deodorization efficiency is lowered due to contamination.

That is, in the prior art, in most deodorizing towers, the bubbles of the salt component excessively generated in the washing liquid storage tank (hereinafter referred to as "chemical liquid storage tank") are removed by the foam removal shower (foam killer), at this time the chemical liquid As well as the various precipitates in the inside, the bubbles of the salt component are dissolved by the washing solution as fine salts to increase the turbidity of the washing solution, and also appear as a side effect of sticking to each part inside the deodorizing device in which the anion salt has a positive cation.

Accordingly, the present applicant developed "Alkali cleaning unit bubble removal and secondary cleaning device of multi-stage deodorizer" as a method for removing salts and bubbles contained in the chemical solution (cleaning solution) in the chemical storage tank among the above problems. Thus, it was presented as Korean Patent Publication No. 10-1232603, and "a non-powered foam removal device for a chemical cleaning deodorizer" was developed and presented as a domestic registered patent publication No. 10-1290761, as well as "Chemical cleaning with a foam and salt removal function" Deodorization device" has been developed and presented as Korean Patent Publication Nos. 10-1608195 and 10-1638429.

However, in all of the above-described chemical cleaning and deodorizing devices (collectively referred to for convenience), there is no removal device for sediment, only bubbles (including foam) and salt removal devices are provided. foam) and salt removal device are also provided separately in the inside of the main body of the deodorizing tower body or on one side of the cleaning solution storage device for simultaneous two-liquid cleaning It has a form that removes bubbles and salts contained in the cleaning solution in the process of being returned to the cleaning solution storage tank of the

However, in the foam and salt removal device having such a configuration, only a portion of the foam and salt generated during cleaning of the odor gas through the injection of chemical liquids, which is the cleaning liquid, is removed from the inside of the main body, or the odor gas is washed into each cleaning liquid storage tank. In the process of water exchange, only some of the foam and salt contained in the cleaning solution can be removed, but various impurities contained in the cleaning solution cannot be removed. Expensive cleaning liquid in each cleaning liquid storage tank is greatly contaminated by various impurity deposits, so the entire amount of cleaning liquid must be replaced. There is a problem that the deodorization efficiency is lowered.

It is possible to extend the entire replacement cycle of the chemical by repeating the operation of re-entering the general operation after performing the cleaning operation, the drain operation, and the chemical liquid replenishment operation in the circulating chemical liquid cleaning tank 90 in the state that the liquid flows into the tank side, In addition, it is possible to significantly reduce the cost due to frequent change of chemical solution, and it is possible to obtain effects such as greatly increasing the water-soluble odor gas removal efficiency using the chemical solution by reducing the solubility of salt by-products. do.

At this time, the known chemical cleaning deodorizer to which the present invention is applied is provided with only a one-stage cleaning unit 51 as shown in FIG. 3 in the main body 50, or a first-stage and two-stage cleaning unit 51 is provided at the same time as shown in FIG. and one or two chemical storage tanks 60 are provided at the bottom of the main body 50 .

In addition, injection rods 52 for spraying a chemical liquid are respectively provided in the upper part of the first-stage and second-stage cleaning unit 51 , and a control unit ( 80), the driving is controlled by one or two circulation pumps 70 that continuously pressurize the chemical liquid supplied in each chemical storage tank 60 to the injection rod 52 side. .

In addition, at the lower outer side of the first and second stage cleaning units 51 , the chemical liquid collecting pipe that collects the chemical liquid that has passed through the first and second stage cleaning units 51 , respectively, and returns it to each chemical storage tank 60 . Each of the 53 is provided, and the outside of the main body 50 basically includes a manipulation unit 82 through which the driver can input various key signals and switching signals, so that a set time can be arbitrarily inputted and at the same time chemical cleaning is performed. It has a form provided with a timer 81 that can continuously count the time when the deodorizer is operated, and a controller 80 for controlling the driving of the one or two circulation pumps 70 described above.

Among the components further applied in the present invention to such a known chemical cleaning and deodorizing device, the circulating chemical cleaning tank 90 has a form separately installed on the outside of the chemical storage tank 60, as shown in FIGS. 2 and 3, and the chemical solution The chemical recovered from the first-stage cleaning unit 51 or the second-stage cleaning unit 51 during the chemical cleaning and deodorizing operation of the cleaning deodorizer is recovered through the chemical collection liquid branch pipe 54 branched from the chemical liquid collection pipe 53 It receives the circulating fluid and gradually overflows it to the chemical storage tank 60 side, and when it passes through the washing unit 51 of each stage, various impurities contained in the circulating chemical are precipitated to the bottom using their own weight, and the floating substances are It floats above the water surface, and performs a function of overflowing only the cleaned circulating chemical to each chemical storage tank 60, that is, collecting and stagnating various sediments and suspended matter therein.

At this time, as shown in FIGS. 2 and 3 , the circulating chemical cleaning tank 90 includes a circulating chemical inlet 92 and a circulating chemical overflowing portion using a diaphragm 94 installed in the tank body 91 ( 93) and, at the same time, on one side of the tank body 91, it has a form composed of an overflow pipe 96 that allows the circulating chemical to overflow to the chemical storage tank 60 side.

Among the components of the circulating chemical cleaning tank 90, the tank body 91 is formed to have a closed cylinder or square cylinder shape with an openable and openable lid, and the volume of the tank body 91 is for storing the chemical solution. It is determined in consideration of the total capacity of the tanks (60), and it is preferable to form a capacity of 5 to 10%, respectively, compared to the total capacity of the general chemical storage tank (60).

In addition, the diaphragm 94 is installed in the vertical direction in the middle of the tank body 91 so that the inside of the tank body 91 is divided into a circulating chemical liquid inlet 92 and a circulating chemical liquid overflow portion 93 . Of course, it has a form in which a circulating chemical solution passing hole 95 having a predetermined height is formed between the lower end and the bottom surface 911 of the tank body 91 .

Accordingly, the lower end of the diaphragm 94 and the tank body 91 by an amount corresponding to the water pressure changed in response to the change in the amount of the circulating chemical liquid flowing into the circulating chemical liquid inlet 92 of the tank body 91 ) through the circulating chemical liquid passing hole 95 formed between the bottom surfaces of the circulating chemical liquid overflow part 93 is continuously flowed over.

In addition, the overflow pipe 96 is installed to communicate between the opposite surfaces of the tank body 91 and the chemical storage tank 60 at the same position as the maximum set water level for the chemical in the chemical storage tank 60 . have

Therefore, the circulating chemical solution flows into the inlet 92 side of the tank body 91 and then through the circulating chemical solution passing hole 95 formed between the lower end of the diaphragm 94 and the bottom surface of the tank body 91 . When the level of the circulating chemical flowing over to the overflow pipe 93 is higher than the installation position of the overflow pipe 96, the corresponding circulating chemical is transferred to the original chemical storage tank 60 through the overflow pipe 96. will automatically overflow.

In addition, in the present invention, a part of the sludge contained in the circulating chemical liquid passing through the circulating chemical liquid washing tank 90 on the upper part of the circulating chemical liquid overflow part 93 formed on one side of the tank body 91 of the circulating chemical cleaning tank 90 . When re-floating to the upper part of the circulating chemical liquid overflow part 93 by the flow (flow velocity) of the chemical liquid, they collide with the swash plate 982 and rapidly re-sediment the swash plate assembly 98 for sludge sedimentation to the bottom side to be detachable installed more.

At this time, in the sloping plate assembly 98 for sludge settling, as shown in FIG. 4 , two pairs of support frames 981 are disposed parallel to each other at a predetermined distance from the upper and lower parts, and the two pairs of support frames 981 are provided. It has a form in which a plurality of swash plates 982 are integrally fixed with a predetermined angle (θ; for example, 55 to 75 degrees) and an interval therebetween.

Therefore, the circulating chemical liquid flowing into the circulating chemical liquid inlet 92 in the tank body 91 of the circulating chemical cleaning tank 90 is disposed between the lower end of the diaphragm 94 and the bottom surface of the tank body 91 . Through the formed circulating chemical solution passing hole 95, it passes to the circulating chemical overflow part 93, and some sludge contained therein is primarily settled on the bottom surface by its own weight, and the remaining part of the sludge flows ( flow rate) to the upper part of the circulating chemical overflow part 93, and at this time, the swash plates 982 provided in the swash plate assembly 98 for sludge settling are sludge unfair to the upper part of the circulating chemical overflow part 93. They are rapidly re-sedimented (secondary) to the bottom side.

That is, the circulating chemical liquid flowing over to the circulating chemical liquid overflow part 93 through the circulating chemical liquid passage hole 95 formed between the bottom surfaces of the tank body 91 floats in response to the flow rate, and the sludge settling swash plate assembly 98 ), the residual sludge contained in the circulating chemical solution collides with the bottom surface of the inclined plates 982 installed at an angle of, for example, 55 to 75 degrees between the two pairs of support frames 981, respectively, and rapidly moves to the bottom side. re-settling.

In addition, in the present invention, when the swash plate assembly 98 for sludge sedimentation is installed on the circulating chemical overflow part 93 formed on one side of the tank body 91 of the circulating chemical cleaning tank 90, the swash plate 982 is circulated. It is installed to be inclined in the direction opposite to the flow direction of the chemical, but the upper end of the swash plate 981 is preferably installed lower than the inner bottom of the overflow pipe 96 .

In addition, when the sludge settling plate assembly 98 is installed on the upper part of the circulating chemical overflow part 93 formed on one side of the tank body 91 of the circulating chemical cleaning tank 90, when it is contaminated or damaged, the tank body ( 91) A plurality of assembly holders (not shown) are further installed on the inner wall of the circulating chemical overflow part 93 so as to be easily separated from the inside of the circulating chemical overflow part 93 formed on one side to perform cleaning and repair smoothly. It is preferable that the swash plate assembly 98 for sludge sedimentation be detachably installed on the upper surface of the assembly support.

Therefore, after the salt suspension and sludge are secondarily sedimented toward the bottom of the tank body 91 through the swash plate assembly 98 for sludge sedimentation, a relatively clear circulating chemical solution flows through the overflow pipe 96 to the chemical storage tank ( 60) When it overflows to the side, for example, it rises obliquely upward along the slope of the slope plates 982 installed inclined at 55 to 75 degrees and overflows, and then the inner bottom part of the overflow pipe having a higher state than the upper end of the slope plates 982 Since it overflows through 96 and moves to the chemical solution supply tank 60 side, the passage time of the circulating chemical solution passing through the swash plate assembly 98 for sludge settling can be increased by that much. The effect of rapid sedimentation of sludge can be maximized.

Therefore, the circulating chemical solution that flows through the overflow pipe 96 toward the chemical storage tank 60 after passing through the sloping plate assembly 98 for sludge sedimentation has a relatively clear state in which sludge including salt by-products is minimally included. Therefore, it is possible to significantly improve the efficiency and reliability of the chemical cleaning and deodorizing machine itself according to the commercial properties and deodorization performance.

In addition, in the present invention, in forming the bottom surface 911 of the circulating chemical cleaning tank 90, that is, the bottom surface 911 of the tank body 91, it is not formed in a horizontal state as in the prior art, but the tank body The circulating chemical liquid overflow part 93 formed in 91 is high, and the drain pipe 131 in which the electromagnetic valve 130 for chemical discharge is installed is inclined so that it is installed or formed to be low.

At this time, the bottom surface 911 of the tank body 91 may be directly inclined as described above, or may be installed to be inclined as described above by forming a separate bottom surface.

In this way, the bottom surface 911 of the tank body 91 is installed or formed inclined so that the circulating chemical liquid overflow part 93 side is high and the drain pipe 131 side where the electromagnetic valve 130 for chemical liquid discharge is installed is low. When the electronic valve 130 for discharging chemical solution installed in the drain pipe 131 is opened in response to the output signal of the control unit 80 , the floating material and sediment including the circulating chemical solution in the circulating chemical cleaning tank 90 are inclined bottom surface Since it flows smoothly toward the drain pipe 131 along the 911, the contaminated circulating chemical solution and sludge, suspended matter and solids in the circulating chemical cleaning tank 90 can be completely automatically discharged without using a separate drain pump, etc. Their emission efficiency can be significantly increased.

In addition, in the present invention, a mesh network 97 was further installed detachably at the entrance of the overflow pipe 96 .

Therefore, when the chemical cleaning and deodorizing machine is in normal operation, the circulating chemical liquid introduced into the circulating chemical cleaning tank 90 slowly passes through the circulating chemical cleaning tank 90, and impurities including sludge are first precipitated, and some suspended matter and sludge are After secondary re-sedimentation through the sludge sedimentation swash plate assembly 98 together with the circulating chemical, cleaning operation for the inside of the circulating chemical cleaning tank 90, including when it finally overflows to the chemical storage tank 60 When this is carried out, various sediments, suspended matter, and solids contained in the circulating chemical in the circulating chemical cleaning tank 90 or in the circulating chemical which is turbid during cleaning by spraying compressed air are removed from the overflow pipe 96. Since it is finally (tertiary) caught by the mesh network 97 installed at the inlet, only the circulating chemical solution in a clear state can continuously overflow to the circulating chemical cleaning tank 90 side.

Accordingly, various sediments, suspended matter, and solids contained in the circulating chemical solution that pass through the circulating chemical cleaning tank 90 overflow to the original chemical storage tank 60 through the overflow pipe 96 and are mixed. It is possible to completely prevent secondary contamination of the original chemical solution that may occur due to the chemical solution, and thus the efficiency and reliability of the chemical cleaning and deodorizing machine itself can be greatly improved.

On the other hand, the first circulation direction selector valve 101 among the first and second circulation direction selector valves 101 and 102 is installed in the chemical liquid collection pipe 53 directly connected into the chemical liquid storage tank 60 , , the second circulation direction switching valve 102 is branched from the chemical liquid collection pipe 53 and installed on the chemical collection liquid branch pipe 54 connected into the circulating chemical liquid washing tank 90 .

The first and second circulation direction switching valves 101 and 102 are opened and closed in opposite directions in response to the output signal of the control unit 80, and are introduced after passing through the cleaning unit 51 of each stage. It performs a function of allowing the circulating chemical to flow into only one side of the chemical storage tank 60 or the circulating chemical cleaning tank 90 through the chemical collection pipe 53 or the chemical collection branch pipe 54 .

In addition, the air compressor 110 performs a function of storing the compressed air storage tank 111 having a predetermined capacity by compressing the outside air in a normal state in a state installed outside the main body 50 .

At this time, between the air compressor 110 and the compressed air storage tank 111, a check valve omitting reference numerals is provided so that the air compressed in the air compressor 110 can be supplied only to the compressed air storage tank 111 side. It is preferable to provide, and in the compressed air storage tank 111, when the pressure in the compressed air storage tank 111 rises above a predetermined pressure, some air is automatically discharged to the outside to promote safety for the compressed air storage tank. It is preferable to provide a check valve that omits the reference numerals given to do so.

In addition, the compressed air supply pump 112 is on the air supply pipe 121 that connects the outlet of the compressed air storage tank 111 and the plurality of air nozzles 120 installed in the circulating chemical cleaning tank 90 . installed form.

It performs a function of supplying a plurality of air nozzles 120 with the air required to give.

At this time, the operating time of the compressed air supply pump 112 is determined by the volume of the circulating chemical cleaning tank 90, its own air output amount and pressure, etc., floating on the surface of the circulating chemical in the circulating chemical cleaning tank 90 It is desirable to determine within 5 to 15 seconds through the control unit 80 so that there is sufficient time to forcibly vortex and drop off the sediment on the bottom surface, including the suspended matter, and the solid material attached to the inside to mix it with the circulating chemical solution. do.

In addition, the plurality of air nozzles 120 are arranged to be uniformly close to the entire bottom surface of the circulating chemical cleaning tank 90 at a predetermined interval from the end of the air supply pipe 121 introduced into the circulating chemical cleaning tank 90 . has the form

These air nozzles 120 evenly spray the compressed air supplied from the compressed air supply pump 112 through the air supply pipe 121 to the bottom surface of the circulating chemical cleaning tank 90 to the entire circulating chemical cleaning tank. The sediment deposited on the bottom surface, including floating substances such as salt by-products floating on the water surface of the circulating chemical in the circulating chemical solution, is vortexed and mixed with the circulating chemical, as well as solid substances attached to the inside of the circulating chemical cleaning tank 90, etc. It falls off and mixes with the circulating liquid to perform the function of transforming the circulating liquid itself into a turbid liquid.

At this time, when the bottom surface 911 of the circulating chemical cleaning tank 90 has an inclined shape as described above, in the interior of the circulating chemical cleaning tank 90 , in the lower portion of the diaphragm 94 . The air nozzle 120 installed in the form of penetrating the formed circulating chemical liquid passing hole 95 is also inclined in correspondence to the inclination angle of the bottom surface 911 of the circulating chemical liquid cleaning tank 90, so that in each air nozzle 120 It is preferable to allow the pressure of the injected air to be evenly sprayed on the entire inclined bottom surface 911 .

In addition, the electromagnetic valve 130 for discharging the chemical solution has a form installed on the drain pipe 131 installed at the bottom of one side of the circulating chemical solution cleaning tank 90 , and is opened for a predetermined time in response to the output signal of the control unit 80 . is automatically closed and performs a function of automatically discharging the turbid chemical solution in the circulating chemical cleaning tank 90 to the outside for a predetermined time.

In addition, the chemical solution supply pump 140 is installed between a separate chemical solution supply container 141 provided on the outside of the main body 50 and the circulating chemical solution cleaning tank 90 in response to the output signal of the control unit 80 It operates, and performs a function of replenishing the new chemical solution in the chemical solution supply container 141 installed on the outside of the main body 50 by a predetermined amount in the circulating chemical liquid washing tank 90 by a predetermined amount by the control unit 80. .

At this time, as a method for replenishing a predetermined amount of the chemical solution in the circulating chemical solution washing tank 90 using the chemical solution supply pump 140 in the control unit 80 , various methods may be suggested, an example of which is circulation. A new chemical solution provided in the chemical solution supply container 141 in the circulating chemical solution cleaning tank 90 by installing a water level detection sensor (not shown) in the chemical solution washing tank 90 to cause the control unit 80 to operate the chemical solution supply pump 140 . It is possible to suggest a method of continuously detecting the amount of chemical solution replenished in the circulating chemical solution washing tank 90 while replenishing it in real time, and blocking the driving of the chemical solution supply pump 140 when a desired amount is replenished.

As another example, a flow sensor (not shown) is installed at the outlet of the chemical solution supply pump 140 , and a desired replenishment amount is previously input in the control unit 80 , and the chemical solution supply pump 140 is operated to operate the circulating chemical solution. When the chemical solution is replenished in the washing tank 90, the amount of the chemical solution replenished in the circulating chemical solution washing tank 90 is continuously detected through the flow sensor, and when a predetermined amount is replenished, the driving of the chemical solution supply pump 140 is blocked. You can also suggest a method.

In addition, the pH detection sensor 150 detects in real time a hydrogen ion concentration (pH) value for the chemical in the circulating chemical cleaning tank 90 in a state installed in the circulating chemical cleaning tank 90, and the control unit 80 It performs the function of forwarding to

In addition, the constant or control water supply pump 160 is installed on the constant or control water supply pipe 161 connected from the outside of the main body 50 to the inside of the circulating chemical cleaning tank 90, the control unit 80 The opening/closing amount is controlled in response to the output signal of It performs a function of minutely supplying an appropriate amount of constant or control water until the pH value in the circulating chemical liquid washing tank 90 detected as a reaches a reference pH value predetermined in the control unit 80 .

On the other hand, in the present invention, in order to automatically replace the contaminated chemical in the circulating chemical cleaning tank 90, as shown in FIG. 5, when the chemical cleaning and deodorizing machine is operating in the normal operation mode, the timer 81 ) to count the time and determine whether the predetermined time has been reached (S1), and when the operation time in the general operation mode (S2) is operated for more than a preset time, the degree of contamination of the cleaning liquid in the chemical storage tank 60 is considered to have risen above the threshold.

Here, the general operation mode operation (S2) performed by the control unit 80 refers to the chemical liquid that passes through each cleaning unit 51 and is circulated in a state containing various impurities through the circulating chemical cleaning tank 90 . It overflows to the chemical storage tank 60, and within the circulating chemical cleaning tank 90, sediments such as various sludges contained in the circulating chemical are precipitated to the bottom using their own weight, and floating substances such as salt by-products float on the surface of the circulating chemical. In order to do this, the first circulation direction switching valve 101 installed in the chemical liquid collection pipe 53 directly connected into the chemical liquid storage tank 60 for a time determined by the timer 81 is closed, and from the chemical liquid collection tube 53 The second circulation direction switching valve 102 installed on the collecting chemical liquid branch pipe 54 branched and connected into the circulating chemical liquid washing tank 90 is opened, and the chemical liquid discharge electromagnetic valve 130 installed on the drain pipe 131 is This means keeping it closed.

That is, when the chemical cleaning deodorizer to which the present invention is applied is operating in the general operation mode, the first circulation direction switching valve 101 is closed for a time determined by the timer 81 by the controller 80, and the second circulation direction The switching valve 102 is open, and since the electromagnetic valve 130 for discharging the chemical on the drain pipe 131 remains closed, the circulating chemical solution passing through each cleaning unit 51 is switched to the second circulation direction in an open state. After continuously flowing into the circulating chemical cleaning tank 90 through the collected chemical liquid branch pipe 54 in which the valve 102 is installed, it gradually passes through the inside, and deposits such as various sludge contained in the circulating chemical liquid are deposited on the floor by their own weight. Since floating substances such as salt by-products float to the surface of the circulating chemical solution, the contamination level of the circulating chemical solution that is continuously overflowed for a set time by the timer 81 through the overflow pipe 96 toward the chemical storage tank 60 is as much as have a low status.

In addition, as described above, when the chemical cleaning and deodorizing device in the control unit 80 is operating in the normal operation mode, the time is continuously counted through the timer 81. It is determined that the contamination level of the cleaning chemical in the tank 60 has risen to more than the standard value, and after being collected through the chemical collection pipe 53 in the above-described general operation mode, the circulating chemical cleaning tank 90 through the collection chemical branch pipe 54 ), in a state in which the circulating chemical liquid flowing into the chemical liquid storage tank 60 is switched to flow into the original chemical liquid storage tank 60 side, and compressed air is sprayed toward the bottom in the circulating chemical liquid cleaning tank 90 through the plurality of air nozzles 120 for a predetermined time. The cleaning operation step (S3) in the circulating chemical cleaning tank in which the suspended solids and sediments including the circulating chemical in the circulating chemical cleaning tank 90 cause a vortex, and the solid material attached thereto is removed from the inner surface and transformed into a turbid chemical. will do

At this time, specifically looking at the cleaning operation step (S3) in the circulating chemical liquid cleaning tank 90 performed by the control unit 80, first, the control unit 80 performs the normal mode operation for a predetermined time through the timer 81. In this case, as opposed to in the normal operation mode, the first circulation direction selector valve 101 is opened and the second circulation direction selector valve 102 is closed to store the circulating chemical liquid that has passed through each cleaning unit 51 into the original chemical liquid storage tank ( 60) side, while continuing to deodorize the odor, the electromagnetic valve 130 for discharging the chemical installed on the drain pipe 131 is kept closed (S31).

Then, the control unit 80 operates the compressed air supply pump 112 for a predetermined time (for example, 1 to 3 minutes as a time sufficient to vortex the circulating chemical solution stagnated in the circulating chemical solution washing tank 90) The compressed air is strongly sprayed toward the bottom in the circulating chemical cleaning tank 90 through the air nozzle 120 of (S32).

As such, the circulating chemical liquid that has passed through each cleaning unit 51 is converted to flow into the original chemical storage tank 60, and compressed air is strongly sprayed toward the bottom of the circulating chemical liquid cleaning tank 90. The circulating chemical solution stagnated in the circulating chemical cleaning tank 90 is vortexed by the jetting force of compressed air, as well as the floating substances on the water surface and the sediment deposited on the bottom surface during the normal operation mode are diluted in the circulating chemical solution which is vortexed and circulated The solid material attached to the inner surface of the chemical cleaning tank 90 is dropped off by the injection pressure of compressed air and the vortex force of the circulating chemical and is diluted in the circulating chemical, so that the circulating chemical that is stagnated in the circulating chemical cleaning tank 90 is turbid. has a transformed form.

In this way, the control unit 80, which has completed the cleaning operation step (S3) in the circulating chemical cleaning tank 90, then opens the chemical discharge electromagnetic valve 130 provided in the drain pipe 131 to the circulating chemical cleaning tank 90. A drain operation step (S4) of completely draining the turbid chemical solution inside is performed.

At this time, as described above, the bottom surface 911 of the circulating chemical cleaning tank 90 has a high portion where the bottom surface of the overflow plate 97 is fixed, and the drain pipe 111 in which the electromagnetic valve 110 for discharging chemical liquid is installed. Since the side is inclined to be low, after completing the cleaning operation step (S3) in the circulating chemical cleaning tank 90, the control unit 80 is provided in the drain pipe 131 to perform the drain operation (S4). When the electromagnetic valve 130 for discharging chemical liquid is opened, the turbid chemical liquid in the circulating chemical liquid cleaning tank 90 is completely drained to the outside along the inclined bottom surface, so contamination in the circulating chemical liquid cleaning tank 90 without using a separate pump It is possible to significantly increase the automatic discharge efficiency of the chemical solution.

Thereafter, the control unit 80 performs a chemical solution replenishment operation step (S5) for replenishing a new chemical solution having a predetermined pH value in the circulating chemical solution washing tank 90 .

That is, when the drain operation for the turbid medicine in the circulating chemical cleaning tank 90 is finished, the control unit 80 operates the chemical supply pump 140 to remove the chemical in the chemical supply container 141 to the circulating chemical cleaning tank 90 . ) to a certain water level (for example, 90 to 95% of the target water level) to the side (S51), and then operate the constant or control water supply pump 160 to replenish the circulating chemical solution washing tank 90 with a new chemical solution Constant or control water is supplied (S52) until the water level in the interior reaches a predetermined level.

Thereafter, the control unit 80 compares the pH value in the circulating chemical solution washing tank 90 detected in real time through the pH detection sensor 150 and the reference pH value written in the control unit 80 itself, An appropriate amount of constant or control water is finely supplied through a method of micro-operating the constant or control water supply pump 160 so that the pH value of the chemical solution newly supplied into the circulating chemical cleaning tank 90 reaches a predetermined reference pH value. (S53) so that the new chemical solution replenished into the circulating chemical solution washing tank 90 has a desired pH value, and the chemical solution replenishment operation is completed.

Then, the control unit 80 resets the timer 81 (S6) as well as closes the first circulation direction selector valve 101 and opens the second circulation direction selector valve 102 in the normal operation mode. It re-enters the operation (S2).

At this time, the number of times of replacing the circulating chemical solution in the circulating chemical solution washing tank 90 is performed a predetermined number of times (for example, 8 to 10 times), and when the replacement of the predetermined number of times is completed, the entire chemical solution in the chemical solution storage tank 60 is replaced. it is preferable

Therefore, it is necessary to frequently replace the chemical solution by various sediments precipitated in the form of sludge as well as reducing the solubility of salt in the chemical solution (ie, cleaning solution) that is generated in the process of removing odor gas using the cleaning chemical and is recovered back to the chemical storage tank 60 side. That is, only the circulating chemical solution in the circulating chemical cleaning tank 90 having a relatively small volume compared to the total volume of the chemical storage tank 60 is replaced and used a predetermined number of times, and only after the replacement is completed for a predetermined number of times, the chemical storage tank (60) Since the entire chemical solution is replaced, the entire replacement cycle of the chemical solution can be extended, and the cost due to frequent replacement of the chemical solution can be greatly reduced.

In addition, by reducing the solubility of salt by-products, it is possible to significantly increase the removal efficiency of water-soluble odor gas using a chemical solution, and to prevent clogging of the chemical cleaning deodorizer by the salt by-product, as well as prevent the increase in turbidity of the chemical solution due to sediment. It is possible to significantly improve the deodorization performance of the deodorizer itself, and in particular, it is possible to prevent blockage of the deodorization tower by salt by-products, thereby greatly improving the deodorization performance.

On the other hand, in the present invention, the cleaning operation in the circulating chemical liquid cleaning tank 90 is automatically performed by the timer 81 at the time determined by the timer 81 in the operation unit 82, or the cleaning operation automatic or A manual selection switch 821 was further installed.

Therefore, when the automatic cleaning operation or manual selection switch 821 is selected as the automatic cleaning operation automatic selection mode by the driver, the control unit 80 performs the normal operation as described above, and a time determined through a timer If the driver switches the cleaning operation automatic or manual selection switch 821 to the cleaning operation manual selection mode while counting, immediately after switching to the cleaning operation manual mode regardless of the count value of the timer, the circulating chemical is cleaned In the tank 90, the cleaning operation step (S3), the drain operation step (S4), and the chemical solution replenishment operation step (S5) are sequentially performed.

Of course, since the above and the driver switch the cleaning operation automatic or manual selection switch 821 to the cleaning operation manual selection mode, immediately after switching to the cleaning operation manual mode regardless of the count value of the timer, cleaning the circulating chemical solution After the cleaning operation step (S3) in the tank 90, the drain operation step (S4), and the chemical liquid replenishment operation step (S5) are sequentially performed, the automatic cleaning operation or manual selection switch 821 is set to the cleaning operation automatic mode. The automatic cleaning process described above is continuously repeated only after switching.

At this time, the number of times of replacing the circulating chemical solution in the circulating chemical solution washing tank 90 is performed a predetermined number of times (for example, 8 to 10 times), and when the replacement of the predetermined number of times is completed, the entire chemical solution in the chemical solution storage tank 60 is replaced. it is preferable

Therefore, it is necessary to frequently replace the chemical solution by various sediments precipitated in the form of sludge as well as reducing the solubility of salt in the chemical solution (ie, cleaning solution) that is generated in the process of removing odor gas using the cleaning chemical and is recovered back to the chemical storage tank 60 side. That is, only the circulating chemical solution in the circulating chemical cleaning tank 90 having a relatively small volume compared to the total volume of the chemical storage tank 60 is replaced and used a predetermined number of times, and only after the replacement is completed for a predetermined number of times, the chemical storage tank (60) Since the entire chemical solution is replaced, the entire replacement cycle of the chemical solution can be extended, and the cost due to frequent replacement of the chemical solution can be greatly reduced.

In addition, by reducing the solubility of salt by-products, it is possible to significantly increase the removal efficiency of water-soluble odor gas using a chemical solution, and to prevent clogging of the chemical cleaning deodorizer by the salt by-product, as well as prevent the increase in turbidity of the chemical solution due to sediment. It is possible to significantly improve the deodorization performance of the deodorizer itself, and in particular, it is possible to prevent blockage of the deodorization tower by salt by-products, thereby greatly improving the deodorization performance.
