On the packing surface, the gas  liquid phases are in full contact with the absorption  neutralization reaction to adsorb the acidic  alkaline dirt contained in the waste gas. After the acid mist exhaust gas is purified, the clean gas will be discharged into the atmosphere  the fan after dewatering  demisting by the demisting plate.

Absorbent liquid is pressurized at the bottom of the tower by water pump  sprayed down at the top of the tower,  finally flow back to the bottom of the tower for recycling. The purified acid mist exhaust gas meets the emission requirements of local emission standards of Guangdong Province  is lower than the national emission standards. General spray tower for industrial dust removal  waste gas treatment. It is mainly composed of filter, multi-stage spray, down dripper, collection room  other components. It is mainly used for the pretreatment of harmful waste gas  adhesive gas,  it can effectively separate the solids in the gas. Spray tower is the main equipment for boiler flue gas desulfurization by limestone wet method. Limestone  limestone powder is used as absorbent, limestone block  limestone powder is made into limestone slurry, limestone slurry is pumped into the absorption tower  the flue gas is fully contacted, so that the flue gas in the SO2

Reaction with CaCO3 in the slurry to generate CaSO4.

the lower part of the absorption tower slurry pool drum into the air, so that CaSO3 oxidation into CaSO4, CaSO4 reaches a certain degree of saturation, crystallization to form CaSO4-2H2O. gypsum slurry discharged  the absorption tower, through the concentration, dewatering, so that its moisture content of less than 10%,  then sent to the gypsum conveyor stacking. The flue gas after desulfurization is discharged into the atmosphere  the chimney after removing mist droplets by mist eliminator.
