An annular venturi scrubber for scrubbing an impurity-laden gas stream with a liquid, in which spaced horizontal baffles are provided at the base of the central conical baffle and the lower extremity of the approach section, with the conical baffle being rotatable or adjustable about a vertical axis, so that the throat opening may be modified to compensate for changes in the gas flow rate.
