FLUORINE GAS GENERATING DEVICE

摘要

A fluorine gas generating device 100 is provided which facilitates the maintenance operation of recovery and replacement of an adsorbing material that adsorbs hydrogen fluoride and supplies fluorine gas in a stable manner. The device comprises a refining line 20 that includes refining devices that, with the aid of adsorbing material, remove hydrogen fluoride gas that has been evaporated from a molten salt of an electrolytic tank 1 and mixed to fluorine gas generated at a positive pole 103a of the electrolytic tank. The refining line 20 comprises a first refining section 21 that includes at least two refining devices arranged in parallel and a second refining section 22 that includes at least two refining devices arranged in parallel and is positioned downstream of the first refining section 21. Fluorine gas that has passed through either one of the refining devices of the first refining section 21 is selectively led to either one of the refining devices of the second refining section.
