<p>The invention concerns a gas scrubber (10) for scrubbing a gas of particles carried by the gas. The scrubber includes a duct (12) for conveying the flow of gas which is to be scrubbed. In the duct the gas, typically air, is mixed with a scrubbing liquid, typically clean water. The gas/liquid mixture is then subject to multiple scrubbing stages each designed to promote good contact between the gas-conveyed particles and the liquid. The first scrubbing stage includes an inductor (48) of reduced transverse dimension. The second scrubbing stage is provided by a transverse barrier (50.4) in the duct against which the gas/liquid mixture is caused to impact. The third scrubbing stage makes use of an impeller (50) which causes the gas/liquid mixture to swirl outwardly and impact against the duct (12). After the scrubbing stages, the gas/liquid mixture is subjected to centrifugal separation in a multi-stage centrifugal separator (49) which separates the liquid and gas components.</p> |
