Benefits of technology

The present invention aims to prevent clogging of pipes and valves during the production of fluorine gas through the electrolysis of an electrolyte containing hydrogen fluoride and a metal fluoride. This invention can protect against the formation of mist that can get into the pipes and valves, leading to clogging.

Problems solved by technology

The mist accompanying fluorine gas becomes fine particles, which may clog pipes and valves used to send fluorine gas.
This may force a production operation of fluorine gas to discontinue or stop and has interfered with continuous operation to produce fluorine gas by the electrolytic method.

first alternative embodiment

[0123]A first alternative embodiment will be described with reference to FIG. 4. In the device for producing fluorine gas illustrated in FIG. 2, the second bypass pipes 52 connect the electrolytic cells 11 to the first bypass pipe 51. In contrast, in a device for producing fluorine gas in the first alternative embodiment illustrated in FIG. 4, second bypass pipes 52 connect first pipes 41 to a first bypass pipe 51. The device for producing fluorine gas in the first alternative embodiment has substantially the same constitution as the device for producing fluorine gas in FIG. 2 except the above structure, and thus similar structures are not described.

second alternative embodiment

[0124]A second alternative embodiment will be described with reference to FIG. 5. A device for producing fluorine gas in the second alternative embodiment illustrated in FIG. 5 includes a single electrolytic cell 11. A first average particle size measurement unit 31 is not provided on a fourth pipe 44 but on a first pipe 41 and is provided at the upstream side of a first pipe valve 61. The device includes no second bypass pipe 52, and a first bypass pipe 51 is directly connected to an electrolytic cell 11 but not through a second bypass pipe 52.

[0125]The first bypass pipe 51 has a larger diameter than the fourth pipe 44 and thus functions as the clogging suppression mechanism. A mist pool space is further provided, for example, at the downstream end of the first bypass pipe 51, and this can further improve the clogging suppression effect.

[0126]Examples of the mist pool space include a space formed from the downstream end portion of the first bypass pipe 51 and having a larger pipe d...

third alternative embodiment

[0128]A third alternative embodiment will be described with reference to FIG. 6. In a device for producing fluorine gas in the third alternative embodiment, a first average particle size measurement unit 31 is provided on an electrolytic cell 11, and the average particle size of a mist is measured by introducing the anode gas in the electrolytic cell 11 directly into the first average particle size measurement unit 31. The device for producing fluorine gas in the third alternative embodiment has no second average particle size measurement unit 34. The device for producing fluorine gas in the third alternative embodiment has substantially the same constitution as the device for producing fluorine gas in the second alternative embodiment except the above structure, and thus similar structures are not described.

Abstract

A method for producing fluorine gas including electrolyzing an electrolyte in an electrolytic cell, measuring an electric energy accumulated after the electrolyte is placed in the electrolytic cell, and the electrolyzing is started, and sending a fluid generated in the inside of the electrolytic cell in the electrolyzing the electrolyte, to the outside of the electrolytic cell through a flow path. In the sending, the flow path is switched in accordance with the electric energy measured in the measuring an electric energy, such that the fluid is sent to a first flow path that sends the fluid to a first outside when the electric energy measured in the measuring an electric energy is not less than a predetermined reference value, or the fluid is sent to a second flow path that sends the fluid to a second outside when the electric energy is less than the predetermined reference value.

Description

TECHNICAL FIELD[0001]The present invention relates to a method for producing fluorine gas and a device for producing fluorine gas.BACKGROUND ART[0002]Fluorine gas can be synthesized (electrolytically synthesized) by electrolyzing an electrolyte containing hydrogen fluoride and a metal fluoride. Electrolyzing an electrolyte generates mist (for example, a mist of the electrolyte) together with fluorine gas, and thus the fluorine gas sent from an electrolytic cell is accompanied with mist. The mist accompanying fluorine gas becomes fine particles, which may clog pipes and valves used to send fluorine gas. This may force a production operation of fluorine gas to discontinue or stop and has interfered with continuous operation to produce fluorine gas by the electrolytic method.[0003]To suppress clogging of pipes and valves with mist, PTL 1 discloses technology of heating fluorine gas accompanied with mist or a pipe through which the gas passes, to a temperature equal to or higher than th...
