Abstract
A device for purifying contaminated gas, such as air drawn from an automobile painting tunnel and containing a mist of paint particles, includes an upper water feed orifice 1 connected to a lower flow channel 4 by an intermediate channel 3 which diverges progressively from top to bottom. A horizontal, transverse wall 8 is positioned beneath the feed orifice at a downstream section of the intermediate channel. Water falling against the wall splashes out in a curtain of droplets through which the air must pass, with the paint particles thus being entrained in the droplets and removed from the air flow. The low divergence angles of the intermediate channel ensures the continuous wetting of its walls to prevent clogging.
