Wet scrubber apparatus and paint spraybooth in combination with wet

Abstract

A wet scrubber is provided for use in combination with a work station in which airborne particulates are generated. The wet scrubber includes a generally horizontal partition which defines a lower boundary of the work station and a discharge structure depending from the partition. A flow of liquid is supplied into the discharge structure, and a flow of air is supplied which will carry the particulate from the work station into and through the discharge structure. A scrubber chamber is also provided into which the discharge structure projects. This chamber includes a receptacle for containing a pool of liquid. The discharge structure itself is constructed to include an elongated inlet channel and a plurality of discrete discharge tubes extending down into the scrubber chamber. The inlet channel has a top, a bottom and a pair of converging sidwalls which depend from the partition at the top of the channel. Each of the discharge tubes has sidewalls and endwalls extending down from the bottom of the channel and together forming a discharge port which is directed at the receptacle within the scrubber chamber. The sidewalls of the inlet channel and the sidewalls of each of the discharge tubes join together or merge to form a generally unobstructed surface, permitting unimpeded flow of the water from the application chamber into the receptable of the scrubber chamber.
