Description

Technical Field

[0001] This utility model relates to the field of sulfuric acid mist exhaust gas purification technology, and in particular to a sulfuric acid mist exhaust gas purification device. Background Technology

[0002] Acid mist gases, when dissolved in water, react to form weak acids, including sulfur oxides, nitrogen oxides, and other compounds. These gases are present in extremely low concentrations in the atmosphere, and in some areas are even undetectable. The presence of acid mist gases increases corrosion of pipelines and equipment, affecting their service life. During the cryogenic separation of natural gas, CO2 may form dry ice, clogging pipelines and equipment; natural gas with a high H2S content produces an unpleasant odor upon combustion, and the resulting SO2 and other compounds pollute the environment; in catalytic processing, sulfur-containing hydrocarbons can poison the catalyst. Therefore, the removal of acid mist gases is one of the main tasks of natural gas purification.

[0003] When existing waste gas purification devices are in use, the waste gas entering the purification device contains a large amount of impurities, requiring staff to disassemble and clean the purification device later. In addition, existing spray devices cannot fully contact the sulfuric acid mist during spraying, thus reducing the treatment efficiency. Therefore, we have proposed a sulfuric acid mist waste gas purification device. Utility Model Content
