[0002] Calcium bromide is a colorless, salty, water-soluble crystal that is highly hygroscopic, similar to calcium chloride. Calcium bromide is an important bromide in industry and can be used to prepare other bromides such as ammonium bromide. Calcium bromide is one of the important raw materials for making photosensitive paper, flame retardants and refrigerants. Its more well-known use is in oil drilling fluids. In addition, calcium bromide can also be used to prepare drugs for nerves. During the production and preparation of calcium bromide, tail gas will be generated, which needs to be absorbed and treated.

[0004] However, the above patent will produce tail gas during the preparation of calcium bromide, which makes it inconvenient to filter and remove impurities in the tail gas. In addition, the tail gas contains chlorine.

Therefore, we propose a new calcium bromide tail gas absorption device to solve the above problems. Utility Model Content
