Abstract: A flame-proof gas-scrubber having a housing adapted to be filled to a predetermined level with a scrubbing liquid, a downwardly extending gas inlet conduit 6, and a series of liquid inlets 16, 24 in a fluid flow path around the outside of the inlet conduit. The liquid inlets communicate with the body of scrubbing liquid well below the level thereof, and a deflector 29 and venturi throat 26 are included concentrically in the fluid flow path for aiding the mixing of the gas and liquid. A skirt 33 surrounds the upper end of the inlet conduit 6 to direct the mixture downwardly above the liquid level to provide for liquid/gas separation.
