Description
Technical Field
The utility model relates to the technical field of bromine blowing production in salt chemical industry.
Background
Acid-process air-blown bromine is a method for producing bromine, and most of domestic production enterprises adopt acid-process air-blown bromine at present. The main process is that the sea water or bittern with low bromine content is first acidified with dilute sulfuric acid, then chlorine is introduced to oxidize the bromide ion in the sea water, and the free bromine Br2 is blown out with air in the blow-out tower. Then sulfur dioxide is used for absorption in an absorption tower, bromine is enriched to form intermediate product absorption completion liquid, and finally, the intermediate product absorption completion liquid is distilled, cooled and separated by a distillation tower to prepare the finished bromine product.
Under the acidic condition, the bromide ions in the seawater are oxidized by chlorine gas to generate bromine molecules, and the reaction formula is as follows:
2Br-+Cl2→Br2+2Cl-
the free bromine is blown out by air, and the blown bromine-containing air is absorbed by a sulfur dioxide absorbent to prepare HBr finished liquid, and the reaction formula is as follows:
SO2+2H2O+Br2→H2SO4+2HBr
adding chlorine into the finished solution, and dissociating bromine, wherein the reaction formula is as follows:
2HBr+Cl2 →Br2+2HCl
the seawater blown out of the blow-out tower by the free bromine Br2 is acidic wastewater mainly containing sulfate ions, and the wastewater is high in acidity and corrosive and can destroy the ecological environment of a salt pan when directly discharged into the salt pan.
