Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a hydrochloric acid gas absorption treatment device. Background Art

[0002] Hydrochloric acid mist comes from the production, storage and transportation of hydrochloric acid in chlor-alkali plants; chemical plants, pesticide plants, and hydrometallurgical plants that use hydrochloric acid as raw materials; hydrochloric acid pickling tanks, the process of cleaning boilers with hydrochloric acid. There are two main ways for acid mist to form. One is the evaporation of the surface of the acid solution, where acid molecules enter the air, absorb water and condense to form acid mist droplets; the other is a chemical reaction in the acid solution that generates bubbles, which float to the surface and then explode, bringing droplets into the air to form acid mist. The hydrochloric acid mist waste gas generated during the production process needs to be treated before being discharged into the atmosphere.

[0003] Hydrochloric acid mist waste gas is usually absorbed and treated using an absorption tower. Existing absorption towers have problems such as poor absorption effect, low efficiency, inability to fully treat hydrochloric acid waste gas, and complex structure. In this regard, we proposed a hydrochloric acid gas absorption treatment device. Utility Model Content
