Description

Technical Field

[0001] The utility model relates to the technical field of compound processing and production, in particular to a reaction tank used for producing barium chloride. Background Art

[0002] Barium chloride is a highly toxic inorganic compound with the chemical formula BaCI2. It is a white crystalline solid and is widely used in the preparation of barium salts, metallic barium and other compounds. The process for industrial preparation of barium chloride is as follows: barite ore (containing BaCO3) is roasted at high temperature using charcoal, followed by the addition of hydrochloric acid (HCI) solution for dissolution reaction. After the reaction is completed, the reacted barium chloride solution is filtered to filter out the unreacted ore residue, and then the barium chloride solution is evaporated and dried to obtain the final barium chloride product.

[0003] The general barium chloride reaction device takes a long time to wait for the crystal ore to be dissolved by hydrochloric acid, and the crystal ore cannot be evenly contacted with the hydrochloric acid during the reaction. It is easy for one side to be dissolved while the other side cannot be contacted with hydrochloric acid. It is easy to cause a series of problems such as blockage caused by the highly toxic crystal ore residue in the device, reducing the reaction efficiency, etc. At the same time, due to the strong acidity of hydrochloric acid, after long-term use, the residual hydrochloric acid after multiple reactions will shorten the service life of the dissolution container and even affect the operating safety of the staff.
