spray tower

タイトルまたは説明

Purified by acid mist exhaust duct into tower, after the packing layer, the waste gas with sodium hydroxide absorption liquid gas liquid two phase fully contact the neutralization reaction, acid mist exhaust after purification, then through mist plate after dehydration mist fan by the atmosphere. The absorber is sprayed on the top of the tower after being pressurized by the water pump, and then it is recycled back to the bottom of the tower. After purification, the acid mist exhaust emissions meet the emission requirements of local emission standards in guangdong province, which is below the national emission standard.

    As a mass transfer device for the two-phase contact member of the air liquid. Packing support plate is installed in the bottom of the packing tower and the packing is placed on the support plate in a random pile. The packing gland is mounted on the top of the packing to prevent the air flow from rising. Spray column spray from the top of the tower is sprayed onto the packing by liquid distributor and flow down the surface of the packing. The gas is fed from the bottom of the tower. After the distribution of the gas distribution device, the liquid will flow upstream through the interstice of the packing layer, and the liquid will be transmitted in close contact with the air liquid on the surface of the packing. When the liquid flows downward along the packing layer, the wall flow phenomenon sometimes occurs, and the wall flow effect causes the distribution of the gas liquid in the packing layer, thus reducing the mass transfer efficiency. Therefore, the packing layer in the spray tower is divided into two sections, and the intermediate redistributing device is set in the middle and sprayed onto the lower layer of filler after redistribution.
