Abstract

A device is provided for scrubbing a polluted gas in which this gas passes through at least one sheet of a scrubbing liquid. The device comprises trickle walls (7) which together define a first opening (8), a first transverse wall (12) disposed beneath the first opening, and a trickle passage with a vertical axis, surrounding the first transverse wall, and limited by two confining walls (10) attached to the underside of the trickle walls on either side of the first opening. Inside the trickle passage, under the first transverse wall (12), further walls (15) are arranged defining a second opening (16), with a second transverse wall (17) being disposed beneath the second opening.
