Problems solved by technology

[0002] As we all know, in the case of nuclear power plant reactor fuel damage, the water vapor in the unit will react with the zirconium in the fuel rod casing to produce hydrogen, which is likely to leak into the reactor containment. After combining with oxygen, there may be explode

Abstract

The invention discloses a hydrogen filter system of a nuclear power station containment. The hydrogen filter system comprises a shell, wherein the shell comprises a shell cover; a first safety valve and a second safety valve are arranged at two ends of the shell cover; a hydrogen filter is arranged at the position of the interior top of the shell, and an electromagnetic valve is arranged on the side wall of the shell; a to-be-filtered hydrogen inlet is formed in the bottom end of the shell, the to-be-filtered hydrogen inlet enters the shell through an internal extended pipe extending to the interior of the shell, and a to-be-filtered hydrogen outlet is formed in the tail end of the internal extended pipe; a first filter screen is arranged above the to-be-filtered hydrogen outlet; and a plurality of gas detectors are arranged in the middle of the first filter screen.

Description

technical field [0001] The invention relates to a nuclear power device, in particular to a hydrogen filter system for a containment shell of a nuclear power plant. Background technique [0002] As we all know, in the case of nuclear power plant reactor fuel damage, the water vapor in the unit will react with the zirconium in the fuel rod casing to produce hydrogen, which is likely to leak into the reactor containment. After combining with oxygen, there may be explode. Therefore, there is an urgent need for a method capable of monitoring the concentration of filtered hydrogen in the containment vessel. Contents of the invention [0003] The present invention aims to provide a nuclear power plant containment hydrogen filter system to solve the above-mentioned technical problems. [0004] An embodiment of the present invention provides a nuclear power plant containment hydrogen filter system, including a housing; the housing includes a cover; the two ends of the cover are p...
