A device for eliminating combustible gas in a closed environment

Abstract

The invention relates to a device for eliminating flammable gas in a closed environment. The device comprises a heat production component, a diversion shield and two fixing plates, wherein the heat production component comprises a rectangular box body and catalyzing boxes; the upper side and the lower side of the rectangular box body have an opened structure; air enters the rectangular box body through an opening in a lower bottom surface from bottom to top; bearing structures for placing the catalyzing boxes are distributed inside the rectangular box body; catalyzing balls are arranged in the catalyzing boxes; the diversion shield has an overall shield structure consisting of a diameter-changed body and a diversion body; one bottom edge of the diameter-changed body on the diversion shield is hinged with one side at the upper end of the rectangular box body, so that the whole device can be opened and closed, and the catalyzing boxes can be assembled and replaced; the side faces of the rectangular box body in both side directions of an air outlet of the diversion shield is provided with one fixing plate respectively; and the device is integrally arranged on a vertical wall surface or a fixed object through the fixing plates. The device can reliably and effectively eliminate the flammable gas in the closed space environment.

Description

technical field [0001] The invention relates to a device for eliminating combustible gas, in particular to a device for eliminating combustible gas in a closed environment. Background technique [0002] Although the nuclear power plant accident is a small probability event, the probability of occurrence is low, but if it occurs, the impact will be huge. Under severe accident conditions, the fuel casing may be completely oxidized, which is an exothermic reaction and produces large amounts of hydrogen gas. In severe accidents, the release rate of hydrogen may reach up to 1kg / s, so certain systems must be adopted in the containment to maintain the hydrogen concentration at a safe concentration, otherwise the enrichment of hydrogen in the containment will increase greatly, so that in the containment A potentially explosive gas mixture is generated inside, and once there is a tiny spark, it can cause a large amount of hydrogen to burn or explode, thereby endangering the integrit...
