Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a spray tower for waste gas treatment. Background Art

[0002] The spray tower is an environmentally friendly waste gas treatment equipment. Its working principle is that when the waste gas containing dust, oil or chemicals passes through the tower body, liquid media will be sprayed out from the appropriate position inside the tower body. These media may be alkaline solution, sulfuric acid solution or circulating water solution. When the waste gas contacts these liquid media, physical and chemical reactions will occur, thereby removing harmful substances in the waste gas. The current acidic or alkaline solutions do not consider that the filtered gas may be acidic or alkaline when discharged when filtering the waste gas, which will cause air pollution. In this regard, a spray tower for waste gas treatment is proposed. When the waste gas is filtered multiple times, the gas is acid-base neutralized to reduce air pollution.
