Apparatus is disclosed for scurbbing contaminants from a gas steam. The apparatus includes a vertically extending cylinrical vessel having an upper gas steam inlet and a lower gas steam outlet. Means are provided for forming an annular venturi gas flow passage fixed within the vessel, and a central opening. A vertically movable plug is supported within the central opening. The plug has a variable cross section and is movable between a position in which the plug closes the central opening and other positions in which portions of the gas stream flow around the plug and through a secondary annular gas flow passage formed within the central opening. A scrubbing liquid supply means is provided above the plug at the center line of the cylindrical vessel. The scrubbing apparatus combines the high efficiency of a fixed-throat venturi scrubber with the compactness, simple construction and low-cost of a plug-type scrubber.
