Description

Simultaneous cleaning of 2 liquid deodorization tower with automatic adjustment of the cleaning liquid level in the cleaning part}

The present invention relates to a two-liquid simultaneous cleaning and deodorizing tower having an automatic adjustment function of the level of the cleaning liquid in the cleaning unit, and more particularly, a single tower is formed in multiple stages, and two or more cleaning liquids are separately circulated to neutralize the odor gas and Automatically adjusts the level of cleaning liquid driven by a reduction gear motor between the first cleaning liquid collection circulation part protruding to the outside of the fine jet nozzle cleaning part and the first cleaning liquid storage tank among the components of the two-liquid simultaneous cleaning deodorization tower by oxidation reaction A means is installed, and a differential pressure detection sensor is installed between the inside of the first-stage cleaning unit and the gas distribution chamber, as well as allowing the control panel to continuously control the internal pressure of the first stage cleaning unit and the odor gas through the differential pressure detection sensor. The pressure of the gas distribution chamber that is flowing in is detected in real time and compared with each other, and after finding the difference, the rotation direction of the reduction gear motor is driven in the forward or reverse direction in response to the mutual pressure difference, but the number of rotations corresponds to the differential pressure. Through a proportional control method, the water level of the cleaning liquid in the first cleaning liquid collection and circulation part is automatically adjusted, and the amount of odor gas flowing into the first-stage cleaning part from the gas distribution room is automatically controlled, thereby simultaneously cleaning and deodorizing two liquids. The present invention relates to a two-liquid simultaneous cleaning and deodorization tower having an automatic adjustment function of the level of the cleaning liquid in the cleaning unit, invented so as to greatly increase the operating efficiency of the tower itself as well as to maximize the cleaning efficiency for incoming odor gas.

In general, in places such as sewage treatment plants, excreta treatment plants, food waste treatment facilities, livestock facilities, etc., various organic or inorganic gases are generated to produce a complex odor, and the resulting odor reacts because the properties are complex with alkali, acid, neutral, etc. With a single chemical cleaning liquid such as a slow oxidizing agent, effective treatment of malodorous gas is difficult.

As a method of removing complex odor gas based on these characteristics, a number of nozzles are installed in the deodorization tower, and the odor is removed by contacting water with the odor-containing gas introduced into the deodorization tower (water washing method). In addition, there is a method in which an adsorbent layer such as activated carbon, silica gel, and zeolite is disposed in the deodorization tower to adsorb odor substances (adsorption method), or a specific microorganism layer is disposed instead of the adsorbent so that the microorganisms prevent odor generating substances. There is a method of decomposing (a microbial contact method).

As described above, the odor gas composed of the complex gas is usually purified by causing a neutralization reaction with a chemical solution of'acid and alkali', and such a conventional deodorization tower has low efficiency due to a slow reaction rate, but an oxidant that reacts in a complex manner (sodium hypochlorite, etc.) A bar consisting of a single deodorization tower using a single deodorization tower or an acid and alkali washing tower each configured in a tandem type connecting two deodorization towers in series, which reduces the deodorization efficiency of the complex gas, Due to the enlargement, installation space and installation cost were excessive.

In order to improve this problem, Korean Patent Publication No. 10-0820845 (name of invention: two-pack simultaneous cleaning and deodorizing tower) has been disclosed.

The two-liquid simultaneous cleaning and deodorization tower proposed in Korean Patent Publication No. 10-0820845 has a mist collecting part and an exhaust port formed above a hollow body, and supplying odor gas to the gas distribution chamber and one outside the distribution chamber at the bottom. A main body in which an inlet pipe is formed so that the odor gas introduced from the fan is introduced; A first tank formed on the bottom of the body and formed to receive an acid washing liquid; a first circulation pump formed on one side of the first tank to transfer the received acid washing liquid to an upper side of the body; and the first circulation pump The first injection pipe having a plurality of supply holes to inject the acid washing liquid transferred by the body toward the lower side, and the first injection pipe formed in the lower part of the first injection pipe to secure the contact area between the odor gas and the washing liquid to the maximum. A pack bed formed to collect malodorous gas, a collecting digger formed to collect the acid washing liquid that passes through the pack bed and falls downward by spraying by the first injection pipe from the bottom of the pack bed, and is formed on one side of the collecting dig A pickling unit provided with a first collecting pipe to transfer the collected pickling liquid to the first tank; A second tank formed on the bottom of the main body, adjacent to the first tank, and formed to receive an alkali cleaning liquid, and a second tank formed on one side of the second tank and formed to transfer the received alkali cleaning liquid to the lower side of the collection ditch of the acid cleaning unit. A second circulation pump, a second supply pipe having a plurality of supply holes to supply the alkaline cleaning liquid transferred by the second circulation pump into the main body, and the alkaline cleaning liquid supplied by the second supply pipe to maintain a constant level. The jet nozzle is formed to remove dust contained in the odor gas while spraying odor gas to clean the odor gas, and the second tank while adjusting the water level of the alkaline cleaning liquid formed on one side of the jet nozzle and circulating. It consists of an alkali cleaning unit that is provided with a second collection pipe for circulation transfer.

At this time, the jet nozzle includes a gas distribution chamber having a plurality of supply pipes; It corresponds to the supply pipe of the gas distribution chamber, but is formed so as to be covered at a predetermined distance from the outer end when combined to form a supply hole, and an injection cap formed to inject into the liquid into bubbles through the supply hole.

The two-liquid simultaneous cleaning and deodorization tower having such a configuration is equipped with an acid and alkali cleaning tower at the same time, and each cleaning liquid circulates separately for cleaning, which can reduce the size of the device, while reducing the size of the device. In addition to ensuring rapid and excellent cleaning power, it was possible to obtain the effect of greatly improving the deodorizing power due to the simultaneous neutralization reaction of acid and alkali.

However, even if a number of the jet nozzles of the two-liquid simultaneous cleaning and deodorizing tower having the above configuration are evenly distributed and arranged inside the main body, the opening ratio cannot be increased in the arrangement, resulting in a large pressure loss. Due to the large width, it is difficult to create microbubbles, and there is a problem that cleaning efficiency is deteriorated due to the large number of bubbles sprayed into the water.

In addition, the two-liquid simultaneous cleaning and deodorization tower is provided with a collection ditch formed to collect the acid washing liquid that passes through the pack bed and falls from the bottom of the pack bed.The collection ditch is simply V-shaped, so that the alkali cleaning solution mist is odorless. Along with the gas flow, it is carried over to the pickling unit, which is a second-stage cleaning unit, and it is mixed with the pickling solution collected in the collecting ditch to neutralize the pickling solution, which reduces the pickling efficiency along with the excessive consumption of chemicals. There was a problem.

Accordingly, the applicant of the present invention aims to solve the above problems (i.e., by increasing the opening rate to reduce pressure loss, to facilitate the generation of microbubbles by miniaturizing the nozzle's nozzle, and the first-stage cleaning solution is accompanied by the flow of odor gas. A two-liquid simultaneous cleaning and deodorizing tower that can minimize carry over to the second-stage cleaning unit has been developed and presented as Korean Patent Publication No. 10-1203420.

As shown in Figs. 1 to 3, the two-liquid simultaneous cleaning and deodorizing tower includes a mist collecting unit 11 and a cleaning liquid mist that is cleaned above the hollow body and collects the cleaning liquid mist contained in the purified air. A purification gas outlet 12 for discharging the collected purified air is provided, and the odor gas from the gas distribution chamber 13 and the odor gas supply fan 14 provided at the outer side of the gas distribution chamber 13 A main body 10 provided with a gas inlet pipe 15 through which the gas is introduced; A first cleaning liquid storage tank 21 provided on the bottom of the body 10 and accommodating a first cleaning liquid, and a first cleaning liquid provided at one side of the first cleaning liquid storage tank 21 and accommodated inside the body 10 A first cleaning liquid having a plurality of supply holes so as to supply the first cleaning liquid transferred by the first cleaning liquid circulation pump 22 and the first cleaning liquid transferred by the first cleaning liquid circulation pump 22 downward in the body 10 The supply pipe 23, provided between the gas distribution chamber 13 and the first cleaning liquid supply pipe 23 and supplied by the first supply pipe 23 to inject odor gas into the alkaline cleaning solution maintained at a constant level. A fine jet nozzle cleaning unit 24 that cleans odor gas to purify odor gas and simultaneously removes dust contained in odor gas, and a fine jet nozzle cleaning unit 24 provided at one side of the fine jet nozzle cleaning unit 24 A first-stage cleaning unit 20 provided with a first cleaning solution collecting and circulating unit 25 for collecting the first cleaning solution in the top 24 and circulating and transferring it to the first cleaning solution storage tank 21; A second cleaning liquid storage tank 31 provided adjacent to the first cleaning liquid storage tank 21 on the bottom of the main body 10 to receive a second cleaning liquid, and provided on one side of the second cleaning liquid storage tank 31 A second cleaning liquid circulation pump 32 for transferring the received second cleaning liquid into the body 10, and a second cleaning liquid transferred by the second cleaning liquid circulation pump 32 downward in the body 10 A second cleaning liquid injection pipe 33 having a plurality of supply holes to spray, and provided under the second cleaning liquid injection pipe 33 to secure a contact area between the odor gas and the cleaning liquid to the maximum to collect odor gas. The second cleaning pack bed part 34 and the odor gas provided under the second cleaning pack bed part 34 and cleaned in the first stage cleaning part 20 are removed from the second cleaning pack bed part 34. And a second cleaning liquid collecting part 35 that is sprayed by the second cleaning liquid spraying pipe 33 to collect the second cleaning liquid that passes through the second cleaning pack bed part 34 and falls downward, and the A second stage cleaning unit 30 provided on one side of the second cleaning solution collecting unit 35 and provided with a second cleaning solution circulating unit 36 for transferring the collected second cleaning solution to the second cleaning solution storage tank 31; It consists of.

Further, the fine jet nozzle cleaning unit 24 is spaced apart from the odor gas supply fan 14 in the odor gas supply direction flowing into the main body 10 and between the odor gas supply direction and the main body 10 A gas inlet plate (24b) provided with a plurality of gas inlet holes (24a) that is formed to be elongated at a right angle in the transverse direction to move the incoming malodorous gas upward, and is provided on the top of the gas inlet hole (24a), The gas is formed in an inverted U shape to cover the gas inlet hole 24a and temporarily collect the malodorous gas moved upward by the gas inlet hole 24a, and the malodorous gas temporarily collected at both lower ends is injected to both sides. Jet nozzle (24d) provided with a plurality of fine jet holes (24c) formed spaced apart in a perpendicular direction in which inlet holes (24a) are formed, and one gas inlet hole (24a) and the gas inlet hole (24a) adjacent thereto A plurality of collision plates 24e that are installed upward from the gas inlet plate 24b located in the middle portion and collide with the malodorous gas moved to both sides by the jet nozzle 24d to refine the malodorous gas and move it upward. ).

On the other hand, in the two-liquid simultaneous deodorization tower having such a configuration, the fine jet nozzle cleaning unit aerated the odor gas through the jet nozzle into the first cleaning liquid, which is an alkaline cleaning liquid, and purifies and removes the odor gas by the cleaning action of the first cleaning liquid. At the same time, it collects dust, which is water-soluble gas particles such as dust contained in the odor gas.

At this time, the level of the first cleaning liquid that is continuously filled between the top surface of the gas inlet plate equipped with the jet nozzles and the bottom surface of the first cleaning liquid supply pipe becomes the main factor determining the aeration amount in the odor gas. Accordingly, it is necessary to adjust the height, and it is necessary to adjust the level of the cleaning liquid according to the state of the odor gas within the range of usually 10 to 30 cm.

However, in most conventional two-liquid simultaneous deodorization towers, the water level of the cleaning liquid in the first cleaning liquid collection circulating part is adjusted. Although not shown, the first cleaning liquid collecting circulator and the cleaning liquid are provided outside the fine jet nozzle cleaning part. 1 Install a valve on the drain pipe installed between the cleaning liquid storage tanks, and adjust the level of the first cleaning liquid according to the state of odor gas by adjusting the opening amount of this valve, or control the operating time of the first cleaning liquid circulation pump Alternatively, another valve is installed between the first cleaning liquid circulation pump and the first cleaning liquid supply pipe, and the level of the first cleaning liquid according to the odor gas state is adjusted by adjusting the opening amount of the valve.

However, adjusting the level of the first cleaning liquid in the fine jet nozzle cleaning unit through this method has a problem in that it is impossible to actively control the water level according to the state of the odor gas flowing into the fine jet nozzle cleaning unit.

In other words, if the two-liquid simultaneous cleaning and deodorizing tower is operated for a long time while the opening amount of the valves is adjusted according to the state of odor gas at the beginning of the operation, the state of the continuously flowing odor gas is changed. In response, it is not possible to actively change the supply amount of the first cleaning liquid that flows into the fine jet nozzle cleaning unit of the deodorization tower, so the two-liquid simultaneous cleaning and the control of the level of the cleaning liquid that continuously changes as the driving time of the deodorization tower elapses is actively changed. There is a problem that cannot be made.

Therefore, as a solution to the above problems, the present applicant developed "a two-liquid simultaneous washing and deodorizing tower having a function of setting the level of the washing liquid in the washing department", and registered Korean Patent Publication No. 10-1893036 (August 2018 23).

The two-liquid simultaneous cleaning and deodorization tower, which has the function of setting the level of the cleaning liquid in the cleaning section, forms a single tower in multiple stages, and separates two or more cleaning liquids to be circulated to purify it through neutralization and oxidation reactions with odor gases. Adjusting and setting the level of the cleaning liquid connected to the first cleaning liquid storage tank through a drain pipe in the central part of the microjet nozzle cleaning part or the first cleaning liquid collection circulation part provided outside the microjet nozzle cleaning part among the components of the simultaneous cleaning and deodorizing tower It is composed of means installed.

On the other hand, the fine jet nozzle cleaning due to an abnormality in the first cleaning liquid circulation system or a user's operation error (for example, a mistake in adjusting the amount of cleaning liquid supplied through the first cleaning liquid circulating pump or a mistake in adjusting the amount of cleaning liquid supply control valve not shown, etc.) When the amount of the first cleaning liquid (hereinafter collectively referred to as "cleaning liquid") collected in the first cleaning liquid collection circulation unit provided at the bottom of the government increases and the level of the first cleaning liquid collection circulation unit rises above the specified level, the first stage tax The pressure within the government increases in response.

In this way, when the water level of the first cleaning liquid collection circulating part is higher than the predetermined level and the pressure in the first stage cleaning part is correspondingly increased, the odor gas supply fan has a certain pressure and flows into the gas distribution chamber above the first cleaning liquid storage tank. Next, since the amount of odor gas passing through the fine jet nozzle cleaning unit and the cleaning solution collected in the first cleaning solution collection circulation unit in the first stage cleaning unit is reduced by that amount, the pressure in the gas distribution chamber is increased.

Therefore, since the required static pressure supplied from the odor gas supply fan is excessively consumed, the driving power of the odor gas supply fan is greatly increased, which increases unnecessary operating costs, as well as the operating efficiency of the two-liquid simultaneous cleaning and deodorization tower itself. There is a problem that the cleaning efficiency for odor gases is greatly reduced.

Of course, contrary to the above, if the water level of the first cleaning liquid collection and circulation unit is much lower than the predetermined level due to insufficient supply of the first cleaning liquid, the pressure in the first stage cleaning unit is significantly lowered accordingly. The amount of odor gas passing through the fine jet nozzle cleaning unit and the cleaning solution collected in the first cleaning solution collection circulation unit in the first stage cleaning unit is increased by that amount, as well as passing through in a short contact time with the cleaning solution. There is a problem in that the cleaning efficiency for gas is greatly reduced.

Nevertheless, in the two-liquid simultaneous cleaning and deodorizing tower (Korean Patent Registration No. 10-1893036) having the function of setting the level of the cleaning liquid in the conventional cleaning unit, the user simply controls the odor gas supplied into the two-liquid simultaneous cleaning and deodorization tower. The condition (state) is checked and judged with the naked eye or through other indications, and according to the inflow condition, it is collected from the outside of the 2-liquid simultaneous cleaning and deodorization tower in the first cleaning liquid collection circulation part and then discharged to the first cleaning liquid storage tank. It adopts a configuration that arbitrarily adjusts the level of the cleaning liquid.

That is, in the above-described Korean Patent Publication No. 10-1893036, the means for adjusting and setting the level of the cleaning liquid manually operated by the user is collected at the center of the fine jet nozzle cleaning unit or outside the fine jet nozzle cleaning unit. Since it has a structure provided in the circulation part, if the supply amount is excessive due to an abnormality in the first cleaning liquid circulation system or a user's operation error, the level of the cleaning liquid in the first cleaning liquid collection circulation part rises sharply, or the water level in the cleaning liquid supply is insufficient. If it decreases rapidly, the user immediately recognizes it and cannot accurately take necessary measures, so the above-described problem is as it is.

Korean Patent Publication No. 10-0820845 (April 02, 2008) Korean Patent Publication No. 10-1203420 (November 15, 2012) Korean Patent Publication No. 10-1485320 (January 16, 2015) Korean Patent Publication No. 10-1893036 (August 23, 2018)

On the other hand, in the present invention, the washing liquid level automatic adjustment means 50 installed between the drain pipe 26 installed between the first washing liquid collection circulation unit 25 and the first washing liquid storage tank 21 is provided as shown in FIG. , A reduction gear motor 51 and a ball screw 52 and a overflow pipe 53 for automatic water level adjustment.

At this time, the reduction gear motor 51 has a form installed in a vertical direction on the upper plate of the first cleaning liquid collecting circulation unit 25 in a state exposed to the outside of the fine jet nozzle cleaning unit 24, and the control panel ( In response to the output signals of the motor forward and reverse driving parts 41 and 42 and the motor proportional control driving part 43, which are driven by 40), the overflow pipe 53 rotates by a predetermined number of rotations in the forward or reverse direction, and automatically adjusts the water level. ) It performs the function of generating the power required for raising and lowering.

In addition, the overflow pipe 53 for automatic water level adjustment is a metal or synthetic resin pipe whose outer diameter is the same as the inner diameter of the drain pipe 26, and has a "+" or "Y" shape in the upper opening so that the source of the cleaning liquid can be smoothly formed. A furnace support plate 531 is formed, and a nut 532 is installed at a central intersection of the support plate 531 so that the ball screw 52 can be screwed.

A portion of the lower portion of the overflow pipe 53 for automatic water level adjustment is detachably coupled to the bottom surface of the first cleaning liquid collection circulation unit 25 through a flange 261 provided on the bottom surface. In response to the number of rotations of the ball screw 52, which has a form inserted into the inside and rotates in the forward or reverse direction by the reduction gear motor 51, it is operated up and down by a predetermined height in the drain pipe 26, and the first cleaning liquid It performs a function of finally adjusting the level of the cleaning liquid that actually overflows from the collection circulation unit 25 to the first cleaning liquid storage tank 21 through the drain pipe 26.

On the other hand, in the present invention, the pressure difference between the internal pressure of the first stage cleaning unit 20 and the gas distribution chamber 13 is obtained through the differential pressure detection sensor 60 in the control panel 40, and corresponding to the difference When the reduction gear motor 51 of the washing liquid level automatic adjustment means 50 is driven at a rotation speed corresponding to the pressure difference in the forward or reverse direction to automatically control the water level of the first washing liquid collecting circulation unit 25, the mutual pressure difference No matter how large, that is, even if the internal pressure of the first stage cleaning unit 20 is relatively higher than the pressure of the gas distribution chamber 13, the reduction gear motor 51 is driven so that the minimum water level does not fall below 10 cm. Contrary to this, control by limiting the drive of the reduction gear motor so that the maximum water level does not exceed 30 cm even if the internal pressure of the first stage cleaning unit 20 is relatively lower than the pressure of the gas distribution chamber 13 I did it.

Therefore, the level of the first cleaning liquid that is continuously filled between the upper surface of the gas inlet plate provided with the jet nozzles and the bottom surface of the first cleaning liquid supply pipe, that is, the cleaning liquid continuously collected in the first cleaning liquid collection circulation unit 25, is 10 to It is possible to automatically adjust in real time in response to the state of the odor gas within the range of 30 cm and the pressure difference between the interior of the first stage cleaning unit 20 and the gas distribution chamber 13.

In addition, in the present invention, a see-through window 251 is further installed on one side wall of the first cleaning solution collecting circulation unit 25 exposed to the outside of the fine jet nozzle cleaning unit 24.

In this way, when the viewing window 251 is installed on one side wall of the first cleaning solution collecting circulation unit 25, the viewing window 251 is collected from the outside of the first cleaning solution collecting circulation unit 25 through the viewing window 251. Changes in the height of the overflow pipe 53 for automatic elevation of the water level automatically raised and lowered by the reduction gear motor 51, including the contamination state of the cleaning liquid and the level of the cleaning liquid automatically adjusted through the automatic adjustment means 50 Can be seen with the naked eye.

In addition, in the present invention, by attaching or printing a ruler scale 252 to the viewing window 251, the overflow pipe for automatic elevation and lowering by the reduction gear motor 51 controlled by the control panel 40 The height of the top of (53) (that is, the water level to be adjusted) can be accurately checked.

Here, the level of the cleaning liquid collected in the first cleaning liquid collection circulation unit 25 of the two-liquid simultaneous cleaning and deodorizing tower to which the present invention is applied is between the internal pressure of the first stage cleaning unit 20 and the pressure of the gas distribution chamber 13 After calculating the difference in the control panel 40, the process of automatically adjusting the water level by operating the reduction gear motor 51 of the washing liquid level automatic adjustment means 50 by the number of rotations determined in the forward and reverse directions based on the difference In contrast, the figures are as follows.

For example, as a result of determination by the control panel 40, the pressure in the first stage cleaning unit 20 compared to the pressure of the odor gas in the gas distribution chamber 13 detected through the differential pressure detection sensor 60 is about -100 mmAg (That is, when the pressure of the odor gas in the gas distribution chamber 13 is, for example, about 200 mmAg, the internal pressure of the first stage cleaning unit 20 is, for example, in the gas distribution chamber 13 When the odor gas pressure is about 100 mmAg, which is about 1/2 of the pressure), the odor gas flowing into the gas distribution chamber 13 is sprayed to the bottom of the first cleaning liquid collection circulation part 25 where the cleaning liquid is collected at a predetermined level. It is determined that the odor gas can be optimally cleaned in the process of passing through the bubble shape and at the same time, dust contained in the odor gas can be optimally removed, and the cleaning liquid level is automatically adjusted. It is assumed that the water level in the first washing liquid collection circulation unit 25 is controlled to maintain 20 cm, which is an intermediate value between the ultra-low water level and the maximum water level through (50).

In addition, when the difference between the desired reference pressure in the first stage cleaning unit 20 and the reference pressure in the gas distribution chamber 13 in which the odor gas is introduced is ±1 mmAg, the control panel 40 collects the cleaning solution. The reduction gear motor 51 provided in the automatic washing liquid level control means 50 is forwardly directed to increase the washing water level in the circulation unit 25 by +1 mm or decrease -1 mm from the reference water level (for example, 20 cm). Alternatively, it is assumed that rotation is performed by a fixed number of rotations in the reverse direction (for example, 2 rotations in the forward or reverse direction).

Under such conditions, as a result of the determination by the microcomputer in the control panel 40 during the operation of the two-liquid simultaneous cleaning and deodorization tower, the differential pressure detection sensor 60 is activated due to an excessive supply of the first cleaning liquid due to an error in the user's operation of the cleaning liquid supply. The pressure of the odor gas in the gas distribution chamber 13 detected in real time is 210 mmAg, which is 10 mmAg higher than the reference pressure (200 mmAg), and the pressure in the cleaning liquid collection circulation unit 25 is the reference pressure 100 ㎜Ag), so when the difference is larger to 110㎜Ag, the level of washing water collected from the control panel 40 into the washing liquid collection circulation unit 25 is, for example, 1cm than the set water level of 20cm. Judge it to be higher.

Subsequently, the microcomputer in the control panel 40 outputs a reverse driving signal to the motor reverse driving unit 42 and at the same time, a reduction gear motor required to lower the overflow pipe 53 for automatic water level adjustment by 1 cm to the motor proportional control driving unit 43 By outputting a rotational speed (for example, 20 times) control signal, the overflow pipe 53 for automatic adjustment of the water level among the components of the automatic cleaning liquid level adjustment means 50 is a reduction gear motor 51 and a ball screw 52 In response to the number of revolutions (that is, 20 times), the water level is automatically lowered to the inside of the drain pipe 26 by 1 cm. It will be lowered automatically by more centimeters.

In addition, contrary to the above, if the pressure of the odor gas in the gas distribution chamber 13 detected in real time through the differential pressure detection sensor 60 due to the lack of the first cleaning liquid supply due to an error in the user's operation of the cleaning liquid supply amount, etc. It is 190㎜Ag, which is 10㎜Ag lower than (200㎜Ag), and the pressure in the cleaning liquid collection circulation unit 25 maintains the reference pressure (100㎜Ag), so the difference is in a state that is smaller to 90㎜Ag. In this case, it is determined that the level of the washing water collected in the washing liquid collection circulation unit 25 by the control panel 40 is lower than the predetermined water level of 20 cm, for example, 1 cm.

Subsequently, the microcomputer in the control panel 40 outputs a forward driving signal to the motor forward driving unit 41 and at the same time, a reduction gear motor required to raise and lower the overflow pipe 53 for automatic water level adjustment by 1 cm to the motor proportional control driving unit 43 By outputting a rotational speed (for example, 20 times) control signal, the overflow pipe 53 for automatic adjustment of the water level among the components of the automatic cleaning liquid level adjustment means 50 is a reduction gear motor 51 and a ball screw 52 In response to the number of revolutions (that is, 20 times), the water level is automatically raised and lowered by 1 cm from the inside of the drain pipe 26, so that the level of the cleaning water in the cleaning liquid collection circulation unit 25 is automatically lowered to the standard level of 20 cm. It will automatically increase by cm.

Of course, unlike the above, as a result of determination by the microcomputer in the control panel 40 during the operation of the two-liquid simultaneous cleaning and deodorization tower, if gas detected in real time through the differential pressure detection sensor 60 due to an abnormality in the first cleaning liquid circulation system, etc. When the pressure of the odor gas in the distribution chamber 13 or the pressure in the cleaning liquid collection circulation unit 25 is higher or lower than the reference pressures (200 mmAg and 100 mmAg), respectively, corresponding to the difference, as described above, Since forward and reverse driving signals are output to the motor forward and reverse driving units 41 and 42, respectively, and at the same time, the reduction gear motor rotation speed control signal corresponding to the current pressure difference is output to the motor proportional control driving unit 43. The level of washing water in the washing liquid collection circulation unit 25 is automatically adjusted to match the pressure difference.

As described above, when the present invention is applied to a two-liquid simultaneous cleaning and deodorization tower, the water level of the cleaning liquid in the first cleaning liquid collection circulating part is stably and actively automatically and in real time through the detection of the pressure difference between the first-stage cleaning unit and the gas distribution chamber.
