Abstract

Disclosed is a gas generation device 100 that has a mist trap 50 a equipped with a tubular housing 51 , a gas inlet port 52 for allowing the gas generated from an electrolytic cell, a gas outlet port 53 for allowing the gas to flow out of the housing, a filler receiving section 58 that is positioned between the gas inlet port 52 and the gas outlet port 53 and receives a filler 56 for adsorbing mist and microparticles, and a gas diffusion section 57 that is positioned between the gas inlet port 52 and the filler receiving section 58 and is for diffusing the gas generated from the electrolytic cell 1 through the housing 51 , that the gas outlet port 53 has a gas inlet tube 55 connecting to the interior of the housing 51 , and that a gas entry portion 59 of the gas inlet tube 55 is arranged so as to be embedded in the filler 56 received in the filler receiving section 58.

First claim

The invention claimed is:

1. A gas generation device for generating a gas by electrolyzing hydrogen fluoride in a molten salt containing hydrogen fluoride, the gas generation device comprises:
an electrolytic cell for generating a gas by electrolyzing hydrogen fluoride in an electrolytic bath comprising a molten salt containing hydrogen fluoride and
a mist trap for removing mist and microparticles, which accompany the gas generation and are derived from the molten salt,
wherein the mist trap comprises:
a tubular housing for allowing the gas generated from the electrolytic cell to flow,
a gas inlet port for allowing the gas generated from the electrolytic cell to flow into the housing,
a gas outlet port for allowing the gas, from which the mist and the microparticles have been removed, to flow out of the housing,
a filler receiving section, that is positioned between the gas inlet port and the gas outlet port, for receiving a filler for adsorbing the mist and the microparticles, and
a gas diffusion section, which is a space that is positioned between the gas inlet port and the filler receiving section, for diffusing the gas generated from the electrolytic cell through the housing, and for roughly removing the mist and the microparticles by attaching the mist and the microparticles to an inner wall of the housing,
wherein the gas outlet port has a gas inlet tube connecting to the interior of the housing, and a gas entry portion of the gas inlet tube is embedded in the filler received in the filler receiving section, such that the gas flowing in the housing is allowed to flow out of the gas outlet port through the filler receiving section and then the gas inlet tube,
wherein the housing is a tubular member arranged in a horizontal direction and having an elongate shape,
wherein, in a longitudinal direction of the housing, the gas inlet port is formed to be closer to one edge surface portion of the housing, and the gas outlet port is formed to be closer to the other edge surface of the housing,
wherein the filler receiving section is arranged in the vicinity of the gas outlet port,
wherein, in a cross section perpendicular to the longitudinal direction of the housing, the filler receiving section has a cross-sectional area that is smaller than that of the housing, such that a flow of the gas in the housing is secured.

2. The gas generation device as claimed in claim 1 , wherein the gas inlet port of the mist trap is arranged such that the gas is introduced from a bottom portion of the housing into the gas diffusion section, in a direction perpendicular to the longitudinal direction of the housing, and
wherein the gas inlet port and the gas outlet port of the mist trap are diagonally opposed to each other in a vertical section along the longitudinal direction of the housing.
