Description

Technical Field

[0001] The utility model relates to the technical field of fluoride tail gas treatment, in particular to a tail gas treatment device for producing rare earth fluoride. Background Art

[0002] Rare earth fluoride is a white powder with a slightly reddish tint. It is obtained by reacting an aqueous solution of rare earth hydroxide or rare earth chloride with hydrofluoric acid. Hydrogen fluoride is the foundation of modern fluorine chemical industry and is the most basic raw material for producing elemental fluorine, various fluorine refrigerants, new fluorine-containing materials, inorganic fluoride salts, and various organic fluorides. During the production of hydrogen fluoride, some exhaust gas needs to be discharged. When treating the exhaust gas of fluoride, its water-soluble property is generally utilized, and the purpose of cleaning the fluoride exhaust gas is achieved through the contact between the exhaust gas and water.

[0003] The current fluoride tail gas treatment device is relatively simple, and the mixing degree between the gas, water and additives is poor, which reduces the purification effect of the fluoride tail gas. Therefore, we propose a tail gas treatment device for the production of rare earth fluoride to solve the above problems. Utility Model Content
