ABSTRACT:
A scrubber module (16) of the wet type includes a partition (26) extending across the upper end of a tank (20) between the dirty flue gas inlet (28) and the clean flue gas outlet (30). The partition (26) takes the form of a plurality of hollow fingers (32), the zigzag lower edge of which is submerged in the aqueous absorbent (22). Oxygen-containing gas such as air is introduced into the lower end of the tank (20) as the partially cleaned flue gas from a baghouse or precipitator (76) is forced underneath the partition (26) at the upper end of the tank to facilitate oxidation and absorption of the sulfur dioxide into calcium sulfate in solution.
