An apparatus (1) for removal under wet scrubbing conditions, combined with centrifugal effects, of entrained particulate and other contaminants from a contaminated gas or vapour phase. The apparatus is of the type comprising a scrubbing liquor sump (2) and a gas or vapour inlet chamber (4) entered eccentrically by a gas or vapour feed passage (5), and adapted for the entrainment of scrubbing liquor from the sump in the contaminated gas or vapour phase introduced into the inlet chamber through the feed passage. The inlet chamber communicates in its central region with a gas or vapour forwarding passage (6) leading into and acted upon by a gas or vapour propelling device, which in turn feeds propelled gas or vapour phase into a downstream disentrainment chamber (9), the apparatus providing a return path for used and disentrained scrubbing liquor back to the sump and an outlet (11) for decontaminated gas or vapour phase. The apparatus includes one or more features selected from the group consisting of: a) at least one outwardly bulging liquor catching formation (18) on a peripheral wall (19) of the downstream disentrainment chamber; b) a centrifugally acting fan (8) to serve as the gas or vapour propelling device; and c) a baffle (24) provided between the sump and the gas or vapour forwarding passage, for moderating the exposure of the scrubbing liquor in the sump to the agitating effect of the gas or vapour phase in the inlet chamber. |
