Taking the operating conditions of the polluted air purification device according to the present invention as an example, when the processing capacity (Q) of the polluted air is 10N.m2/min (however, the temperature condition (correction) is ignored),

1) Blower operating pressure: 550mmH2O

Blower specification: 3P 380V 60Hz/5HP/Direct acting 3550rpm

2) Air velocity passing through dust collection module: V = Q÷(A*60)

Scrubber body cross-sectional area (A): 384mm * 165mm = 0.063㎡ (based on inside)

V = 10÷(0.063 * 60) = 2.65m/sec

3) Air speed of purified air transfer duct pipe: V = Q÷(A*60)

Purified air transfer duct pipe cross-sectional area (A): id 150㎜ = 0.0177㎡

V = 10÷(0.0177 * 60) = 9.4m/sec

4) Air velocity through the venturi nozzle: V = Q÷(A*60)

Venturi nozzle cross-sectional area (A): gap 24mm * width 66mm * 2nd row = 0.0032㎡

V = 10÷(0.0032 * 60) = 52.1m/sec

5) Circulation pump specification: 3P 22V 60Hz/0.25HP/70LT/min * h 6Mr/diameter 40A

Design lift: 2.6MR → Pump flow rate is about 162LT/min

6) Circulating water flow rate: Q = V*A

Water supply pipe cross-sectional area (A): id 20㎜ = 0.000314 * 4 pieces = 0.0013㎡

Q = 60ㅡ/min * 0.0013 = 0.078㎡/min(78LT/min)

7) Expected supercharge return valve flow rate: 162 (pump flow rate) - 78 (circulating water flow rate) = 84LT/min. At this time, by adjusting the flow rate of the return valve, the main water supply amount can be adjusted to allow proper operation.

8) pressure loss

→ Dust collection module (160㎜H2O*3 stage = 480㎜H2O) + Demister (60㎜H2O) + Purified air transport duct and other (10㎜H2O) = 550㎜H2O

9) For example, recovery (removal) of harmful acid gas by diluting basic (caustic soda) chemical solution with washing water treatment, recovery of sulfur gas with caustic soda: SO2 + 2NaOH + 1/2O2 → NaSO4 + H2O, hydrochloric acid gas with caustic soda Recover: HCL +NaOH → NaCL +H2O

The operating state of the polluted air purifying device of the present invention composed of the above device is as follows.

The polluted air flowing in through the contaminated air inlet duct 100 flows into the dust collecting module 300 at the bottom provided on the upper part of the water tank 210, and the water for cleaning in the water tank 210 is circulated by the circulation pump 220. is supplied to the water supply unit 400 along the water supply pipe 230 by the operation of the water supply unit 400, the water supplied to the water supply unit 400 flows down to the water flow pipe 410, ) is supplied.

In this way, the cleaning water supplied to the water supply unit 400 through the water supply pipe 230 by the circulation pump 220 is a water flow pipe provided in each of the multi-stage dust collection modules 300 , 300 ′, and 300 ″. After flowing down sequentially through 410, it flows to a position close to the venturi nozzle 321 by the water supply guide member 323. At this time, the polluting gas ejected from the outlet of the narrow neck of the venturi nozzle 321 is By scattering the flowed water upward, the pollutant particles in the polluting gas are naturally dissolved in the water and removed. It is possible to increase the cleaning efficiency by contacting them.

In addition, by installing the valve 322 in the middle of the narrow neck of the venturi nozzle 321, it is possible to prevent a loss that may occur due to a pressure change irregularly generated at the left and right outlets during gas-liquid contact.

On the other hand, when the continuously supplied water overflows above the water level maintenance plate 325 , it overflows and flows through the water flow pipe 410 by gravity to the dust collecting modules 300 ′ and 300 at the lower stage.

Then, the supplied water overflows under the dust collecting module 300 " of the uppermost stage and the dust collecting module 300' of the middle stage immediately below the water supply unit 400 and overflows into the dust collecting module 300 of the lowermost stage. The water flowing down is returned to the lower water tank 210 along the water flow pipe 410 and can be continuously reused by the circulation pump 220 .

At the same time, the polluted air, which is accelerated through the dust collection modules 300, 300 ', and 300" and has an upward velocity pressure, flows upward, and the water for cleaning, which is about to flow downward by gravity, is dispersed in the multi-segment wave of the dispersing unit 330. The water is dispersed as if it were split into several pieces using the minute groove 331. That is, water washing caused by the action of droplets, liquid film, bubbles, etc. generated by vigorous gas-liquid contact so that the air knife acts in a zigzag manner to break up in the reverse direction, Oxidation and neutralization efficiency can be improved.

The water tank 210 is miniaturized so that only an appropriate amount is maintained for operation of the multi-stage dust collection module 300,300'300", and the previously used water through the water supply pipe 230 by the circulation pump 220 is reused, but a new water supply pipe ( 240), a flow rate similar to that of water is discharged through the overflow pipe 250 to prevent a decrease in cleaning efficiency due to the accumulated use of previously used contaminated water for a long time and to save water consumption.

In addition, the water for cleaning at the top of the gas-liquid contact part is kept constant by the water level maintaining plate 325, and when the facility is stopped by concave the shape of the drain member 324 into a funnel shape, water naturally flows down and the residual water this will not be left A drainage member 324 formed in an inclined shape of a reverse venturi structure was installed to intensively contact gas-liquid water in a narrow space with flowing water. ") so that no water remains in the dust collecting module (300, 300', 300"), the accumulation does not occur inside.

And, it is very difficult to uniformly match the flow rate supplied to the water supply pipe 230 with the pressure of the circulation pump 220, so the water supply unit 400 is installed at the top of the dust collecting module 300 " of the uppermost stage, and each After making the thickness of the water flow pipe 410 provided in the scrubber body 310 the same, the washing water is allowed to fall by gravity so that the flow rate is uniform without a change, thereby enabling stable operation.

Therefore, the polluted air introduced through the polluted air inlet duct 100 passes through the venturi nozzle 321, which is an exhaust polluted air accelerator, to increase the speed pressure in a pressurized type, and is directed from the bottom to the top, and for cleaning Water flows from the upper part to the lower part so that potential energy by gravity acts through the water supply part 400 provided on the upper part of the dust collection module 300 ", so that the polluted air of high velocity pressure falls by gravity. It acts as an air knife in a zigzag motion as if splitting into several pieces and makes vigorous gas-liquid contact so that it is broken down in the reverse direction. Optimization can increase efficiency and reduce waste of usage.

In addition, the polluted water recovered while passing through the dust collection modules 300, 300 ', and 300" and the removed harmful, toxic, odor and fine dust materials are naturally accumulated without sticking to the inside of the dust collection modules 300, 300', 300". It is discharged to overflow, and it maximizes gas-liquid contact reaction efficiency by making the same action in multiple stages of three or more stages of the dust collection module (300, 300', 300"). The installation area can be minimized by making it very compact compared to the size of the same treatment flow rate without the accumulation of contaminants.
