Abstract:
1. A wet scrubber to clean contaminated gases, comprising: a. a vertically oriented structure having a lower section, a middle section, and an upper section, a gas intake pipe at the lower section to bring contaminated gases into the scrubber and a gas exhaust pipe at the upper section to carry clean gases out of the scrubber; b. an immersed packed bed in the lower section of said structure and above said gas intake pipe, wherein said packed bed being immersed in a scrubbing liquid, whereby said contaminated gases being forced through the immersed packed bed as gas bubbles; c. a mixing chamber located immediately above the immersed bed and at substantially the middle section of the structure; d. a mixing fan located outside of the structure and being connected to said mixing chamber through an inlet duct to receive a fluid from the mixing chamber and an exhaust duct to blow said fluid back into the mixing chamber, thereby enhancing the mixing process inside the mixing chamber; e. said exhaust duct having baffles to generate an upward moving flow; f. multiplicity of mist sprayers to spray a scrubbing liquid into the mixing chamber, said sprayers located immediately above the mixing chamber and substantially uniformly distributed across the cross section of the mixing chamber; and g. a mist eliminator located immediately above the mist sprayers; and h. a draft fan to induce gas flow inside the scrubber,
