932,858. Contacting gases with liquids. SVENSKA FLAKTFABRIKEN A.B. May 11, 1961 [May 12, 1960], No. 17311/61. Class 55 (2). Gas purification apparatus comprises a separator 21, a Venturi-shaped gas inlet channel 22 to said separator, the inlet channel having a converging inlet portion 22a terminating in a throat portion 22b and a diverging outlet 22c extending from the throat to the separator, a washing liquid supply means at the upper port of 22 to form a downflowing film of washing liquid on the walls, a flange 10 in the throat portion to disperse and admix the downflowing liquid into the gas, and in the throat portion below the flange slots through which a regulated flow of washing liquid from a supply tank 12 surrounding the throat flows down the walls of the outlet portion of the supply channel. The gas enters the apparatus via the supply duct 4 and passes into the inlet channel 22 where it is washed and admixed with washing liquid which is supplied from the annular trough 26 via the perforations 27 in the bottom of the trough. In order to prevent dust deposits at the mouth of 4 an inflow of air is provided by duct 8 to flow through the apertures 9 into the chamber 23 and then through the clearance space between trough 26 and duct 4. The tank 12 is constructed in such a manner that air enters the slots with the liquid. Fan 25 provides the suction for drawing the gas through the apparatus.
