<p>A spray-type scrubber (10) for removing pollutants from a gas including a scrubber chamber (14) having a gas inlet (16) and a gas outlet (18), liquid spray discharge nozzles (28) within the chamber, and baffles (20) providing a flow of gas to be scrubbed through the chamber (14) from the inlet (16) to the outlet (18) in a manner providing contact of the gas with sprayed liquid in the scrubber chamber (14) so as to effect transfer of pollutants from the gas to the liquid. Pulsations are imparted to the gas flowing through the scrubber chamber (14) by a pulse generator (12) associated with an inlet gas duct (44) leading to the gas inlet (16) of the scrubber chamber (14) which is of reduced cross-section relative to the cross-section of the scrubber chamber (14). The pulse generator (12) includes a rotor (34) having an axis externally of the duct (44) and having a diameter larger than the diameter of the duct (44), and blades (35) adapted to cut across the flow of gas in the inlet duct (44) to provide the pulsations therein.</p> |
