Problems solved by technology

[0004] However, the existing hydrogen recombiners generally have the following defects: the application of traditional catalytic plates is limited by space and scenarios, and the installation arrangement is not flexible
For example, the application of traditional hydrogen recombiner in the narrow space of nuclear power plants is less effective

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] This embodiment provides a novel passive hydrogen recombiner design using a modular unit structure, such as figure 1 As shown, it includes the recombiner body (that is, the catalytic area formed by the module units) and the outer casing 3 . It is characterized in that a gas inlet 1 and a catalytic component fixing device 5 are arranged at the bottom of the recombiner, and a gas outlet 2 is arranged at the top.

[0024] The hydrogen recombiner adopts a modular unit 6 structural design.

[0025] The component units 6 are arranged on the fixing device 5 in a certain regular array, and the array may be rectangular, rhombus, or circular.

[0026] The fixing device 5 is used to fix the assembly unit 6 . Including but not limited to the form of lower support.

[0027] Said assembly unit 6 is a structural part containing the cataly...

Abstract

The invention discloses a novel passive hydrogen recombiner adopting an assembly unit structure. The hydrogen oxygen recombiner comprises a recombiner shell and a recombiner body of the assembly unit structure. The recombiner shell forms a flow channel structure for protection and working of the internal catalysis assembly, the lower portion is an airflow inlet, and the upper portion is an airflow outlet. The recombiner body is an area where a catalyst is located and is used for dehydrogenation reaction under accident conditions of a nuclear power plant. Compared with a conventional hydrogen compounding design structure, the novel passive hydrogen recombiner adopts an assembly unit structure design, and a flexible arrangement form can be provided so as to adapt to application requirements of different spaces and scenes.

Description

technical field [0001] The invention belongs to the field of hydrogen removal devices in the nuclear energy industry sector, and in particular relates to a passive hydrogen recombiner adopting a component unit structure. Background technique [0002] In the course of a serious accident in a pressurized water reactor nuclear power plant, the zirconium alloy cladding of part of the fuel in the reactor core reacts with water vapor at high temperature, and the reactor core melt reacts with concrete to produce a large amount of hydrogen. When hydrogen is transported in the containment, it mixes with the air and water vapor in the containment to form a flammable gas mixture in some spaces of the containment. Under certain conditions, the mixed gas will form a temperature and pressure load in the container after combustion, and once the hydrogen gas mixture deflagrates or even explodes, it will endanger the integrity of the containment vessel and cause serious consequences for the ...
