An improved scrubbing apparatus is disclosed which is particularly well suited for use in spray booths for extracting particulate matter entrained in a gas stream flowing therethrough. The scrubbing apparatus of the present invention combines an elongated throat and an elongated trough positioned therebelow which cooperate to define a first elongated constriction through which the gas stream is drawn. The trough also includes an angularly extended portion which defines a second constriction through which the gas stream is subsequently directed. Flood sheets are also provided across which a continous flow of liquid is passed which becomes atomized as it flows through the first and second constrictions so as to thereby effect a scrubbing of the gas stream and removal of the entrained particulate matter. The first constriction also serves to substantially reduce passage of air or gas thereacross when the apparatus is not in operation. Also, an improved air baffle arrangement is provided to effectively remove liquid from the gas stream before it is discharged.
