Description

Technical Field

[0001] The utility model relates to the technical field of purification equipment, in particular to a cold-rolled strip steel acid mist purification device. Background Art

[0002] Acid mist usually refers to misty acidic substances. The particles of acid mist in the air are very small, smaller than those of water mist, and higher than the humidity of smoke. The particle size is 0.1-10μm. It is a substance between smoke and water mist and has strong corrosiveness. It includes acid mist formed by inorganic acids such as sulfuric acid, nitric acid, and hydrochloric acid, and organic acids such as formic acid, acetic acid, and propionic acid.

[0003] The existing technology is relatively rigid. When acid mist is treated and purified, the existing treatment and purification are divided into liquid absorption method and solid adsorption method. Most of them adopt the liquid absorption method. The liquid absorption method dissolves the acid mist in water mist and drops it to the bottom of the purification box. The acid mist gas is purified and the purified gas is discharged. In the process of water mist purification, some particles in the acid mist that have not come into contact with the water mist will adhere to the inner wall of the purification box and the inner wall of the box cover. If they are not cleaned for a long time, the purification effect of the acid mist will be affected. Therefore, it is necessary to design a cold-rolled strip acid mist purification device to solve the above-mentioned problems. Utility Model Content
