Description

Technical Field

[0001] The utility model relates to the technical field of calcium fluoride, in particular to a reactor for producing calcium fluoride. Background Art

[0002] Calcium fluoride is an inorganic compound with the chemical formula CaF2. It is a colorless crystal or white powder. Its crystal structure belongs to the isometric system and is a cube, octahedron or dodecahedron. Density 3.18g / cm 3 , melting point 1402℃, boiling point 2500℃, refractive index 1.434. It is insoluble in water, slightly soluble in inorganic acid, but soluble in hydrochloric acid, hydrofluoric acid, sulfuric acid, nitric acid and ammonium salt solution, insoluble in acetone. It forms a complex when dissolved in aluminum salt and iron salt solution, and reacts with hot concentrated sulfuric acid to generate hydrofluoric acid.

[0003] In the production process of calcium fluoride, the pressure change in the reactor is a parameter that needs to be closely monitored. This mainly depends on the specific conditions and operation methods of the production process.

[0004] First, the production process of calcium fluoride involves the generation of gas or the volatilization of reactants at high temperatures, and the pressure in the reactor will increase. This is because in a closed environment, the increase in the number of gas molecules will lead to an increase in pressure. At this time, in order to avoid safety problems that may be caused by excessive pressure in the reactor, such as rupture or leakage of the reactor body, appropriate pressure relief operations are required.

[0005] However, the existing reactor does not have an automatic pressure relief function. In order to ensure the stable production of calcium fluoride, it is necessary to manually check its pressure regularly, which is prone to accidents, and there is no good automatic internal cleaning function.

[0008] Preferably, a protection frame is provided at the bottom of the reactor body, and the protection frame is located on both sides of the pressure relief pipe.
