Description

Technical Field

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

[0002] In the chemical industry, due to the need of chemical reactions, chlorine gas is used as a raw material, and hydrogen chloride tail gas is often generated through chlorination reactions to obtain chlorine-containing chemicals. By absorbing with water, by-products hydrochloric acid is generated and recycled. When absorbing hydrogen chloride, hydrogen chloride is filtered to remove impurities in hydrogen chloride, thereby improving the quality of hydrochloric acid.

[0003] However, the prior art still has deficiencies. In the prior art, the replacement of the filter is very cumbersome, increasing the workload and reducing the efficiency.

[0004] Therefore, we propose a hydrochloric acid circulating absorption device to solve this problem. Summary of the Invention
