Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen fluoride production, in particular to a feeding device for hydrogen fluoride production. Background Art

[0002] Hydrogen fluoride is a colorless, pungent-smelling inorganic compound composed of hydrogen atoms and fluorine atoms. It is chemically very active and is one of the strong acids. It can completely dissociate into hydrogen ions and fluoride ions in water. Hydrogen fluoride is a colorless, pungent-smelling liquid with a boiling point of 19.5 degrees Celsius and a high density. It dissolves in water to form a hydrofluoric acid solution.

[0003] With the development of science and technology, hydrogen fluoride has been widely used. Hydrogen fluoride needs to react during the processing and production process. During the reaction, some solid substances insoluble in hydrogen fluoride (such as impurities in the reaction product, catalyst particles, etc.) may exist in hydrogen fluoride. When further processing and feeding are carried out after the reaction is completed, there is a lack of filtering function for impurities and particulate matter, which affects the further processing and production of hydrogen fluoride. However, if the filtering function is simply added, when the impurities and particulate matter that need to be filtered are disassembled and cleaned, good operating efficiency cannot be achieved, which reduces the practicality of the device.
