Abstract 1,056,067. Gas-scrubbers. BUELL Ltd. Oct. 29, 1963 [Nov. 6, 1962], No. 41949/62. Heading B1R. In a gas scrubber the gas to be scrubbed is passed through a Venturi-tube 11 drawing water from a reservoir 6 through a conduit 15 and a mixture of gas and water is discharged upwardly into a horizontally mounted cylindrical chamber 1 in which the mixture of gas and water is separated centrifugally, part of the water being returned to the reservoir 6 through an opening 16 and part being fed to the Venturitube through a conduit 17 and the scrubbed gas is withdrawn through an outlet 18 after passing through blades 19 to remove entrained water. A spray 25 is dispersed in the gas inlet chamber 10 and a semi-circular baffle for guiding the flow of the mixture of gas and water may be provided within the chamber 1.
