[0002] With the rapid development of industrialization, waste gas treatment has become an important issue in the field of environmental protection. As a commonly used waste gas treatment equipment, the spray absorption tower mainly works by contacting the waste gas with the spray liquid, so that the harmful substances in the waste gas are absorbed by the liquid or chemically reacted to remove them.

[0003] When treating waste gas, the traditional spray absorption tower, although its basic principle is to absorb harmful substances or remove them by chemical reaction by contacting the spray liquid with the waste gas, the spray liquid may be sprayed unevenly, which leads to excess liquid in some areas of the tower, while other areas may lack sufficient liquid for effective contact with the waste gas. This uneven distribution directly limits the gas-liquid contact area, which in turn affects the efficiency of harmful substances in the waste gas being absorbed by the liquid, thereby reducing the waste gas treatment efficiency. Therefore, we propose a high-efficiency spray absorption tower. Utility Model Content
