Abstract
A gas scrubbing plant having a gas scrubbing stage, a washing liquid separating stage and a stage for washing out suspended matter therebetween. This latter stage includes a plurality of gas baffles which accelerates the gas and then decelerates it while liquid is introduced into the gas baffles as the gas passes therethrough. Each baffle has an inner conical member surrounded by an outer member to define therebetween an annular passage with diverges at an angle of between 10.degree. and 90.degree. from the inlet adjacent the apex of the conical member to the outlet from the baffle, the cross-sectional area of the annular passage decreasing in the direction of gas flow and then increasing towards the outlet. A liquid feed tube is mounted in the conical member and a disc mounted at the outlet of the tube opposite the apex to the conical member so that the liquid fed into the tube is deflected and produces a rotationally symmetrical jet up into the annular passage in the direction of gas flow from the inlet to the outlet.
