SYSTEM FOR GENERATING FLUORINE GAS

摘要

Disclosed is a system for generating fluorine gas by electrolyzing hydrogen fluoride contained in a molten salt, the system being equipped with: an electrolytic vessel having a first gas chamber into which a main product gas comprising, as a main component, fluorine gas yielded on an anode immersed in the molten salt is introduced and a second gas chamber into which a by-product gas comprising, as a main component, hydrogen gas yielded on a cathode immersed in the molten salt is introduced, the first and second gas chambers being separate from each other over the surface of the molten salt; a hydrogen fluoride supply source in which hydrogen fluoride to be supplied to the electrolytic vessel is stored; a purifier in which hydrogen fluoride gas that has volatilized from the molten salt contained in the electrolytic vessel and has come into the main product gas yielded on the anode is collected to purify the fluorine gas; and recovery equipment for recovering the hydrogen fluoride gas collected by the purifier and transporting the hydrogen fluoride gas to the electrolytic vessel or the hydrogen fluoride supply source.
