An air washer or scrubber, particularly for paint spray booths and especially adapted for removing paint particles from air passing downwardly through the grille floor of a paint spray booth and against a water-washed subfloor, comprises an elongated V-shaped slot in the subfloor extending along the longitudinal centerline of the booth. The inner edges of the walls forming the V-shaped slot are upturned to form ledges so that water flowed over the subfloor and the walls of the slot impinges against the ledges and is thrown upwardly and inwardly to form a curtain of water completely covering the slot. Exhaust means pulls paint-laden air from the spray chamber through the water curtain and the slot and into an expansion chamber, the bottom walls of which form a second V-shaped slot contiguous with the first mentioned slot. The water, in which virtually all of the paint particles are entrained, and the air are discharged from the second slot and impinged against a baffle sheet angling downwardly away from the expansion chamber. The end of the sheet is upturned at a small angle to deflect the water and form an umbrella of water through which the air must pass for a final cleaning action. An optional curved deflector plate positioned beneath the umbrella of water aids in separating the water and air so that only clean, dry air is exhausted to atmosphere.
A gas scrubbing or washing device for use in conjunction with a liquid-washed subfloor sloping toward a longitudinally extending slot in the subfloor, means for flowing liquid over the subfloor and into the slot, and means for drawing gas downwardly through the slot for admixture with the liquid, comprising, downwardly convergent, generally V-shaped walls leading from the subfloor to the slot, said walls terminating in upturned ledges spaced from each other to form the slot, the angle of said walls and said ledges and the width of said slot being such as to cause liquid to impinge against said ledges and to be thrown upwardly and inwardly thereby so as to cover the slot with a dense curtain of liquid, the angle of said walls and the width of said slot being such as to cause gas to enter the slot and the curtain of liquid at an uniformly accelerating velocity so that the liquid and gas in the slot create a dense, sponge-like aerated mass within which particulate matter entrained in the gas is transferred to and entrained in the liquid.
A method of treating a gas with a liquid by passing the same downwardly through a longitudinally extending slot in the bottom of a liquid-washed subfloor, comprising the steps of:
