Embodiment Construction

[0035] The invention discloses a hydrogen igniter device for eliminating hydrogen in a gas medium. The gas medium is preferably an inert gas, such as helium, neon, argon, krypton, xenon and / or radon, and the inert gas is used as the gas medium Since the igniter only needs to remove the impurity substances (including hydrogen), and due to the chemical inertness of the above-mentioned gas, the igniter will not react with it, so its working efficiency can be improved and the use and consumption of filler can be reduced. The use of inert gas can also effectively reduce the adverse effects on the structural components of the igniter, such as the housing, thereby prolonging its service life and reducing maintenance costs.

[0036] The hydrogen igniter of the present invention comprises a shell with a gas medium gas supply port and an exhaust port, bismuth oxide and / or lead oxide placed in the shell. If the bismuth and / or lead in the shell does not exist in the form of oxides, such a...

Abstract

Disclosed is a hydrogen igniter for igniting hydrogen contained in a gaseous medium, said hydrogen igniter comprising a housing with openings for the supply and discharge of a gaseous medium, and a filler in the form of bismuth oxide and / or lead oxide, disposed inside the housing. Also disclosed are a system for purifying a gaseous medium of hydrogen having such a hydrogen igniter, and a method for the repeated use of such a system. The igniter and the system can be used in a nuclear reactor facility.

Description

technical field [0001] The invention relates to a system and a device for eliminating hydrogen in a gas medium, in particular to a hydrogen igniter. Background technique [0002] An important part of ensuring the safe operation of nuclear reactors is to remove hydrogen from the nuclear reactor gas circuit, because the accumulation of gaseous hydrogen may reach dangerous concentrations, resulting in adverse interactions between it and structural materials, resulting in degradation of these materials (mainly electrical circuits) Oxide film on the upper surface of the component). In addition, the accumulation of hydrogen in the gas path is also a prerequisite for it to reach the explosive concentration limit. [0003] In order to remove the hydrogen in the gas path, the following methods are used in the prior art: [0004] Russian patent RU2430876 discloses a device for removing hydrogen from a gaseous mixture. The working principle of the device is based on a gas permeable ...
