Equipment overview

Water Scrubber is a new type of waste gas treatment equipment. It is developed on the basis of the floating packing layer gas purifier, and is widely used in the pretreatment of industrial waste gas purification and dust removal, and the purification effect is very good. Because its working principle is similar to the washing process, it is named washing tower.

Equipment application range

(1) Various harmful gases such as acid mist (H2S04), hydrogen chloride (HCL) and hydrogen fluoride (HF), chromic acid mist (CrO3), hydrocyanic acid (HCN), hydrogen sulfide (H2S), ammonia (NH3), Treatment of water-soluble gas and odorous gas such as alkali steam;

(2) Deodorization device of sewage treatment plant;

(3) Waste gas treatment in the seepage water storage tank of the landfill;

(4) Waste gas treatment from incinerators and industrial furnaces.

(5) Exhaust treatment in semiconductor optoelectronics industry, printed circuit board industry, electroplating, pre-treatment, chemical industry, silicon material cleaning, printing industry, pharmaceuticals, etc.;

Equipment principle

Water Scrubber generally adopts gas-liquid countercurrent operation. The fan group of the scrubber system sucks the collected waste gas into the scrubber, and flows through the filling layer (gas/liquid contact reaction medium), allowing the waste gas to flow with the liquid medicine on the surface of the filling (Washing liquid) Full contact to absorb the acidic or alkaline dirt contained in the exhaust gas. After washing, the waste liquid is collected in the sump, and then discharged to the wastewater system for treatment.

Water Scrubber materials are mainly made of glass fiber reinforced plastic (FRP) and polyvinyl chloride (PP), and can also be made of polypropylene (PVDF), polyethylene (PE), and stainless steel. Standard equipment for vertical scrubber: window and maintenance manhole, air inlet flange, outlet flange, washing liquid inlet, overflow outlet, filling layer, demister layer, circulating water pump, circulating water filter screen, circulation It is composed of water pipelines, sprinklers, accessories and control instruments.
