Title:
METHOD OF DECONTAMINATING WASTE GAS AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2003/082445
Kind Code:
A1
Abstract:
Electrolysis of sea water is performed so as to form an alkali solution and an acid solution. Waste gas to be treated is subjected to gas-liquid contact with the acid solution, and then to gas-liquid contact with the alkali solution. Waste gas decontamination apparatus includes at least one gas-liquid contact means (1) for effecting gas-liquid contact between waste gas to be treated and a treatment solution and an elecrolyzer (16) capable of electrolyzing a salt water into an alkali solution and an acid solution. The at least one gas-liquid contact means (1) is provided with an inlet for waste gas to be treated (5) at an upstream side thereof and provided with an outlet for treated waste gas (6) at a downstream side thereof. At least one gas-liquid contact zone (3A, 3B) arranged thereinside is provided with acid solution spraying means (4A) for spraying the above acid solution or alkali solution spraying means (4B) for spraying the above alkali solution.
