Abstract:
A scrubber for scrubbing gases, comprising:a scrubbing vessel for containing a bath of scrubbing liquid, said vessel having a reaction zone, and a quiescent zone; a conduit having defined therein an intake for receiving gases to be scrubbed; said conduit having a first wall and outlet porting defined therein, said porting defined in said wall for immersion in a scrubbing medium, said conduit defining a passage through which gases can be transported from said intake to said outlet porting, said porting including a first array of slots defined in said first wall; said conduit being mounted to said vessel to present said porting in an immersed position relative to the scrubbing liquid in said reaction zone, whereby gases exiting said porting can mix with said scrubbing liquid in said reaction zone; a partition having said reaction zone lying to one side thereof, said partition being a second wall bounding a settling column, said partition having an upper edge over which scrubbing liquid can drain into said settling column and circulate back to said bath; a third wall intermediate said first wall and said second wall, said third wall having a second array of slots defined therein; when said conduit is immersed in said scrubbing medium, said porting being submerged and extending between a first depth and a second depth; a turbidity interrupter located between said quiescent zone and said reaction zone, said turbidity interrupter being a barrier having channels therein, said channels communicating between said quiescent zone and said reaction zone; and said slots of said first array of slots being separated from one another by fingers, said fingers encouraging formation of more than one stream of bubbles through said porting.
