Abstract

A fluorine gas generating device 100 which is characterized by having a cylindrical member 31 a for circulating therein the main-product gas, a gas feed port 51 a for introducing the main-product gas into the cylindrical member 31 a , a gas discharge port 52 a for discharging the main-product gas from the cylindrical member 31 a , an adsorbent holding member 201 arranged in the cylindrical member 31 a to form a space to provide a channel for the main-product gas circulated in the cylindrical member 31 a , a stirring blade 202 for stirring the main-product gas that is introduced through the gas feed port 51 a , and a gas flow guiding cylinder 203 for circulating or diffusing the main-product gas in the space within the cylindrical member 31 a.

First claim

The invention claimed is:

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.

2. A fluorine gas generating device as claimed in claim 1 , in which the gas flow guiding cylinder has a tubular shape with both ends opened and the gas flow guiding cylinder is arranged in the cylindrical member to extend along an inner surface of the cylindrical member.

3. A fluorine gas generating device as claimed in claim 1 , further comprising a circulation channel that circulates part of the main-product gas discharged from the cylindrical member and thereafter leads the part of the main-product gas into the cylindrical member again.
