[0002] Acid mist usually refers to misty acid substances. In the air, the particles of acid mist are very small, smaller than those of water mist and with a higher humidity than smoke. It is a substance between flue gas and water mist and has strong corrosiveness. Acid mist is mainly generated during the use of acids in industries such as chemical engineering, electronics, metallurgy, electroplating, textile, and machinery manufacturing, such as acid production, pickling, electroplating, electrolysis, and acid battery charging. In addition, during some scientific research processes, different acids are also used. Since the acid processes often use mixtures of multiple acids, the discharged waste gas mostly contains mixtures of multiple acid mists.

[0003] In the prior art, there are still certain drawbacks in the use of acid mist scrubbers. The fillers inside the acid mist scrubber are usually filled flat in the tower, resulting in a large diffusion area of acid mist. The acid mist near the tower wall is not easily mixed with the sprayed liquid, causing some acid substances not to be washed and purified and being discharged into the air with the gas, resulting in air pollution. Content of the Utility Model
