Description

Technical Field

[0001] The utility model relates to the technical field of bromine recovery, in particular to a recovery device for stably supported bromine. Background Technique

[0002] Bromine is a dark red-brown liquid and the only non-metal element in the liquid state at room temperature. It evaporates quickly at room temperature. Its vapor has a strong suffocating and irritating smell, is red-brown, and is slightly soluble in water. Bromine is an important production raw material. After the bromine generated in the production processes of chemical industry and pharmaceutical raw materials is simply washed and recovered, and the bromine is separated, the hydrobromic acid therein is neutralized with sodium hydroxide, mainly used for preparing bromides, and is widely used in fields such as high-efficiency flame retardants, refrigerants, oil completion fluids, medicines, fuel intermediates, and chemical reagents. Bromine is very volatile and can freeze into a solid at low temperatures, and has extremely strong toxicity and corrosiveness. In order to prevent environmental pollution caused by the volatilization of bromine, a recovery device is needed to collect it.

[0003] The Chinese patent publication number is CN220311273U, and the authorization announcement date is January 9, 2024. A recovery device for bromine tail gas in bromine production includes a base, a reaction kettle assembly, an air suction assembly, a cooling assembly, and a recovery assembly. The left side of the top of the base is fixedly connected with a second support plate, and the reaction kettle assembly is fixedly connected to the top of the second support plate. The right side of the top of the base is fixedly connected with a recovery assembly. By starting the air suction assembly, the bromine tail gas generated during the production in the reaction kettle assembly is introduced into the recovery assembly along the air pipe. And when the gas passes through the heat conduction sheet in the cooling assembly, the heat is adsorbed and introduced to the surface of the heat dissipation aluminum sheet for heat dissipation treatment. And by starting the second fan, it is convenient to accelerate the heat dissipation of the heat dissipation aluminum sheet, so that the heat dissipation aluminum sheet can dissipate heat cyclically, and it is convenient to cool the bromine gas in the tail gas, so that the waste gas of bromine is reduced below the boiling point.
