Venturi scrubber

This Venturi scrubber efficiently removes submicron dust particles from gases with temperatures up to 230ºC (450ºF) at the inlet. A quencher added to the inlet accommodates higher-temperature gas streams. The scrubbing liquid is introduced through open pipes — not nozzles — into the Venturi throat. This route ensures uniform liquid distribution, eliminating wet-dry line buildup in the fully wetted section. Dust-laden gas and scrubbing liquid collide in the throat, dispersing the liquid into drops on which the particles impact and become trapped. An optional adjustable throat allows flexible operation with varying flow rates or dust concentrations. An entrainment separator efficiently removes droplets from the gas stream. An integral recycle tank is optional. The outlet may be either vertical or horizontal.
