Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a waste gas treatment oxidation tower. Background Technology

[0002] Waste gas treatment towers are core equipment in the industrial field for removing harmful substances from waste gas. Through physical adsorption, chemical reaction, and gas-liquid contact, they transform pollutants, dust, droplets, and other substances in waste gas into harmless substances or easily collectable states, thereby achieving the goal of meeting gas emission standards. They are widely used in industries such as chemical, printing, pharmaceutical, and food processing, and are one of the key devices for controlling air pollution.

[0003] A search revealed Chinese Patent Publication No. CN112169565A, which discloses an oxidation tower for waste gas treatment. The tower includes an oxidation tower with a spray water outlet at its bottom and a spray water purification layer at the bottom of its inner cavity. A waste gas inlet is located near the bottom of the tower, and a gas outlet is located near the top. A spray device, in a ring structure, is fixedly installed on the inner wall of the tower. An isolation plate is positioned above the spray device, and a filter pipe is installed on the isolation plate. A purification sponge for absorbing atomized liquid is fixedly installed inside the filter pipe. A heating plate is fixedly installed on the inner wall of the oxidation tower above the isolation plate. The beneficial effect of this invention is that the residence time inside the oxidation tower is increased by the purification sponge and the gas purification layer, resulting in a better oxidation effect.

[0004] The existing technology still has the following drawbacks in its use: Existing oxidation towers cannot remove odors from exhaust gases. A spray blind zone is formed in the central area of ​​the tower, and some exhaust gases in the center do not come into contact with the spray liquid, making it impossible to remove dust, soluble acid and pollutants, resulting in incomplete treatment. Existing oxidation towers cannot determine whether the purified gas still contains pollutants, and may cause secondary pollution due to incomplete treatment.
