Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a chemical waste gas purification tower. Background Technique

[0002] Chemistry, that is, the chemical industry. Any process that uses chemical methods to change the composition or structure of substances or synthesize new substances belongs to chemical production technology, that is, chemical technology. The products obtained are called chemical products or chemical industrial products. Existing chemical waste gas purification towers need to treat various waste gases, which contain a large amount of corrosive, toxic, volatile and other components. Adhering to the inner wall of the purification tower will cause the equipment to be easily corroded during long-term use, with greater maintenance difficulty and reduced service life.

[0003] For example, the patent with publication number CN202320911419.7 discloses "A Chemical Waste Gas Purification Tower". The driving motor drives the driving shaft to make the trapezoidal scraper rotate along the inclined plane at the top inside the tower body, and drives the cleaning component to rotate. When the U-shaped frame in the cleaning component rotates, the spring pushes the side wall scraper to closely scrape the inner wall of the tower body, which, in cooperation with the trapezoidal scraper, can effectively reduce the adhesion of waste gas adhesion impurities containing corrosive, toxic, and volatile components on the inner surface wall of the tower body, thereby reducing the maintenance frequency.

[0004] The above-mentioned method uses a scraper to clean the inner wall of the tower body. When the waste gas is purified, the waste gas itself will carry certain impurities. When the waste gas carrying impurities contacts the alkaline solution, the filter plate, and the absorption layer, the purification reaction effect of the waste gas will be reduced due to the impurities, which is not conducive to the purification effect of the waste gas.
