Abstract
A horizontal tubular housing is supported at one of its ends across the top of a stack and a blower is mounted at one end of the housing for moving gases discharged from the stack through the housing. The housing has a plurality of laterally disposed baffle plates arranged such that when impinged by the moving stack gases, the latter will be directed in a tortuous path, preferably an initial spiral path and a subsequent zig zag path. Some of the baffle plates are adjustable to vary the turbulence of the gases in their tortuous movement. Spray nozzles are mounted in the housing at most of the baffle plates to provide curtains of liquid spray for washing the gases. The housing has a liquid drainage outlet in its bottom wall intermediate its ends, and such bottom wall is inclined downwardly from opposite ends of the housing to the outlet to provide drainage. Adjustable louvers are provided in the outlet of the blower to vary the direction of air movement from the blower across the stack.
