Description

Technical Field

[0001] The utility model relates to an air blowing device for a bromine production purge tower, belonging to the technical field of bromine production. Background Art

[0002] Bromine is a key chemical raw material and a major component of the marine chemical industry. The diverse range of inorganic bromides, bromates, and bromine-containing organic compounds derived from it holds special value in the national economy and scientific and technological development. With the development of the national economy and the continuous development of bromine-based products, the importance of bromine has become increasingly prominent, and its production has continued to expand, with continued growth. In recent years, in particular, the technology for extracting bromine from underground brine and concentrated seawater has seen rapid progress, utilizing advanced domestic and international technologies.

[0003] Authorization publication number CN205398109U discloses a nozzle for a bromine blow-out tower, comprising a brine pipe, a blow-out tower, and a nozzle.
