摘要: A wet-process stack gas purification method and apparatus wherein stack gas is scrubbed by bubbling it into a first scrubbing liquid while maintaining the level of the first scrubbing liquid. The above scrubbed gas is subjected to a counter-current contact with a second scrubbing liquid in a scrubbing tower to further purify the gas. The method and apparatus can attain a highly remarkable decontamination effect, and the apparatus is simple in structure and small in size.
