Abstract

726,889. Purifying liquids; treating sewage. SULZER FRERES SOC. ANON. Dec. 31, 1953 [Jan. 31, 1953], No. 36392/53. Classes 46 and 111. [Also in Group XII] In treating liquids with gases in apparatus wherein liquid flows over a surface through an aperture in which gas is introduced, the gasliquid mixture produced being conducted through a rising conduit, the liquid flow is so adjusted that at the gas entry point the component of velocity of liquid perpendicular to the gas direction is 20-40 times S/n, and the mean velocity of the flow of mixture is 3-30 times # log H/D, where S=liquid surface tension, n its viscosity, e the ratio of the sum of the volume of gas and liquid in the mixture to the volume of gas at the point where the mixture enters the rising conduit, H the height of the conduit and D its mean internal diameter. A bubble washer for absorbing carbon monoxide in liquid containing a copper salt from gas mixtures comprises a liquid inlet chamber 1 and a rising conduit 6 separated by a gas chamber 3 with numerous nozzles of convergent-divergent form extending between its walls. Gas admitted through an inlet 7 and annular slot 9 enters the nozzles through slots 5 perpendicular to the upward liquid flow. Absorption liquid is withdrawn through an outlet 13 and residual gas through a pipe 12. The extractor effect of the nozzles may be supplemented. by a blower. In a modification gas enters through several apertures in the walls of a vertical pipe entering the base of a vessel constituting the rising conduit, or the gas apertures may comprise perforations in a rotating drum. The rising conduit may taper upwardly or downwardly and be divided by upright partitions. Gas may be introduced under pressure, the mixing being effected under e.g. 4-6kg/cm<SP>2</SP> pressure.
