Abstract:
A wet gas stripper for separating particulate matter entrained in a moving gas stream comprising:(a) a housing including a plurality of walls and a gas inlet for receiving the moving gas stream into the housing and a gas outlet through which the moving gas stream is exhausted from the housing:(b) a particulate collection area formed at a base of the housing;(c) liquid spray means for spraying a stream of liquid against at least one of the walls of the housing above the particulate collection area in a direction which intersects the moving gas stream and then collides with the wall to create a particulate-entraining turbulent mist, said mist defining a filtration medium for capturing the particulate matter entrained in the gas stream and carrying the particulate matter to the collection area for removal from the housing, said liquid stream colliding with sufficient force to generate negative ions whereby the liquid mist acquires an electrostatic charge to capture the particulate matter entrained in the moving gas stream, said housing being constituted by a rectangular duct defined by top and bottom walls having joined thereto a pair of opposing side walls and a plurality of spaced baffles bridging the side walls and alternately spaced from the top and bottom walls to create a series of intercoupled stations through which the gas stream fed into the gas inlet at one end of the duct travels up and down through the successive stations in the series in a sinuous path toward the gas outlet at the other end of the duct, said spray means in each of said stations being mounted on said one of the side walls to project a liquid stream at high velocity to intersect the gas stream flowing through the station and collide with the opposing side wall to produce said particulate-entraining mist.
