Abstract

Abstract 901,715. Washing gas. AMERICAN AIR FILTER CO. Inc. Dec. 21, 1959 [Dec. 31, 1958], No. 43300/59. Class 55 (2). Gas to be washed is directed on to the surface of a liquid in a sump 3 and (Fig. 2), passes with entrained liquid into sinuous conduits between plates 9 and 11, drains 16 being arranged to catch and remove from the apparatus a proportion, e.g. one sixth, of the liquid projected from the upper edge of the plate 11. Made-up liquid is supplied through a perforated pipe 18 below the working level of liquid in the sump to cause turbulence of the liquid and increase the amount of liquid entrained by the gas. As shown in Fig. 3, a curved baffle 27 may be arranged in the upper part of a sinuous conduit dividing the gas and liquid passing therethrough into two streams, the liquid in one of the streams being withdrawn through a drain 16.
