Abstract:
1. A fluorine gas generating device that generates fluorine gas by electrolyzing hydrogen fluoride in molten salt containing the hydrogen fluoride, the fluorine gas generating device comprising: an electrolytic tank that generates at an anode side a main-product gas, containing fluorine gas as a main component, and at a cathode side a by-product gas, containing hydrogen gas as a main component, by electrolyzing hydrogen fluoride in the molten salt in the electrolytic tank; and a refining device that removes hydrogen fluoride mixed with the main-product gas by using an adsorbent, wherein the refining device comprises: a cylindrical member for receiving therein the main-product gas, a gas feed port for introducing the main-product gas into the cylindrical member, a gas discharge port for discharging the main-product gas from the cylindrical member, an adsorbent holding member holding the adsorbent, wherein the adsorbent holding member is installed in the cylindrical member in a manner to form a gas flow channel, a gas flow guiding cylinder installed in the cylindrical member around the adsorbent holding member, wherein the main-product gas can be guided along the inner and outer cylindrical surfaces of the gas flow guiding cylinder; and a stirring blade arranged to force the main-product gas just led into the cylindrical member from the gas feed port to flow toward an outer channel while suppressing a direct flow of the main-product gas toward the adsorbent holding member; wherein the stirring blade is arranged between the gas feed port and the adsorbent holding member with respect to a direction in which the main-product gas from the gas feed port is directed, and wherein the stirring blade is rotated in a direction to force the main-product gas from the gas feed port back toward the gas feed port.
