Brief introduction of wet spray scrubber

Longtai wet spraying washing tower structure and principle: the waste gas and water or aqueous solution adding chemicals, contaminants into the water, filling packing caused a large contact surface with gas phase to liquid phase neutralization, so as to achieve the purpose of purifying waste gas.

Mass transfer equipment for filling layer of liquid column as gas-liquid two phase contact component. Exhaust gas purification device is arranged at the bottom of the spray tower tower packing support plate, filling with intricate place in the support plate. A platen is placed above the packing to prevent the upward air from blowing. The spray liquid is sprayed from the top to the packing by the liquid distributor and flows down the packing surface. The gas is sent from the bottom of the tower and is distributed in reverse flow with the liquid after the gas distribution device is distributed. Through the gap of the packing layer, the gas-liquid phase is contacted closely and the mass transfer is carried out on the surface of the packing.

When the liquid flows down the packing layer, sometimes the wall flow occurs. The wall flow effect results in uneven distribution of the gas-liquid phase in the packing layer, thus reducing the mass transfer efficiency. Therefore, the packing layer in the exhaust purification device of the spray tower is divided into two sections, and a re distribution device is arranged in the middle, and then sprayed to the lower padding after being redistributed.

In order to prevent the gas from carrying the spraying liquid, the gas water separator at the top of the tower can effectively intercept the spraying liquid. The spray liquid is used in circulation, and there will be partial loss in use. The circulating water tank at the bottom of the tower will be duly replenished with spraying fluid.

Application of wet spray scrubber:

1. PCB Factory: electroplating, pickling, etching.

2. electroplating factory: electroplating, pickling, immersion plating, etching.

3. pharmaceutical factories: grinding, adding, screening, filling.

4. waste gases from various chemical plants and food factories.

5. waste gases from boilers and incinerators.

6. mechanical processing factory oil pollution.

7. dust and combustion gases from various industries.

Deodorization device for 8. sewage station.

Characteristics of wet spray scrubber

1., high absorption and dust removal efficiency.

2. maintenance operation cost is low.

3., with the use of requirements, can be used in addition to polypropylene material other than the material.

4. running pressure reduction can handle large air flow.

5. can be widely used and various types of industries.
