Combined wet scrubber for airborne dust and gases - removing entrained dust or gas in venturi scrubber followed by packed column

摘要

Gas scrubber combines venturi scrubber for dust laden streams with irrigated packed column for removing noxious gases also present. Gas is accelerated to 50-120 m/sec. in a central pipe or venturi. At the base, the stream must turn sharply through 180 degrees and this causes significant removal of airborne material. The gas stream then passes at lower velocity into a scrubbing section which forms an annulus around the venturi. The gas finally passes through a droplet eliminator and is thenexhausted.
