Title: FLUORINE GAS GENERATION DEVICE
Abstract:
Disclosed is a fluorine gas generation device that generates fluorine gas via electrolysis of hydrogen fluoride. Said fluorine gas generation device is provided with an electrolysis vessel in which a first air chamber and a second air chamber are partitioned off separately above the surface of a molten salt. A primary product gas, of which fluorine gas generated at an anode is the main component, is directed into the first air chamber, and a by-product gas, of which hydrogen gas generated at a cathode is the main component, is directed into the second air chamber. The fluorine gas generation device is further provided with: a main channel, which is connected to the first air chamber; a manometer that measures the pressure in the first air chamber; a pump which is provided on the main channel and pumps fluorine gas out of the first air chamber; a reflux passage that connects the discharge side and suction side of the pump; a pressure-regulating valve, provided on the reflux passage, for returning fluorine gas discharged by the pump back to the suction side of the pump; and a control device that, on the basis of measurements from the manometer, controls how open the pressure-regulating valve is so that the pressure in the first air chamber reaches a pre-set value.
