Venturi scrubber consists of a venturi shaped air passage with water entry in the high velocity throat. The water may be introduced either by overflow or through nozzles and is broken un into fine droplets by the action of the high velocity gas stream. Particle conditioning takes place in the throat and as the gas decelerates in the diffuser section. The dispersed material in the dirty gas is deposited on the droplets by impaction, diffusion and condensation.
