HWS

The hydrodynamic type collectors are classified in the medium energy category. Usually, the gas stream is made to impinge on the surface of the scrubbing liquid and is forced through constrictions where the gas velocity is increased and where the liquid-gaseous-particulate interaction occurs. Collection efficiency is about 90 to 94% for 2-um particles. Water usage for orifice collectors is limited to evaporation loss and removal of collected pollutants. HWS type wet scrubber are constructed of welded mild steel plate reinforced with rolled steel angles, the unit consists of two main section – the main reservoir and the upper assembly, connected by a flanged horizontal joint above the water surface. Access doors are sited at all strategic points. All internal surfaces are treated with three coats of hard surface bituminous paint corrosion hazards. Stainless steel can be employed. External surfaces are protected by primer or other finish according to the customer’s requirement.
