Embodiment Construction

[0016] See attached figure 1 , a hydrogen elimination unit with an explosion-proof function, which includes: a cooling fin 1, a shell 2, and a granular catalyst 3 filled in the shell 2;

[0017] The shell 2 is a composite structure of inner and outer layers, which includes: an explosion-limiting partition and a stainless steel wire mesh coating; the stainless steel wire mesh coating is 24 to 30 mesh, and the thickness of the explosion-limiting partition is 0.1mm to 1.0mm ;The explosion-limited partition and the stainless steel wire mesh cladding layer are solidified and bonded by welding;

[0018] The heat dissipation fins 1 are installed on the outer surface of the housing 2, the height of the fin plate is 0.1-0.3mm, and the thickness of the fins is more than 3mm; it increases the heat dissipation area and is used to quickly transfer the heat of hydrogen-oxygen reaction to the airflow and Make the reaction temperature distribution in the explosion-limited partition more unif...

Abstract

The invention belongs to the technical field of hydrogen elimination and explosion protection, and specifically relates to a hydrogen elimination unit. According to a technical scheme in the invention, the hydrogen elimination unit with an explosion-proof function comprises: heat dissipation fins (1), a shell (2), and a particle catalyst (3) filled in the shell (2), wherein the shell (2) comprises an explosion-controlling partition plate and a stainless steel wire mesh coating layer; and the heat dissipation fins (1) are arranged on the outer surface of the shell (2). The hydrogen elimination unit provided by the invention can be used for air with a hydrogen content which is more than 4% and surpasses the lower hydrogen explosive limit, can be directly applied in safe elimination of high-concentration hydrogen, and eliminates a blast accident due to leakage of the high-concentration hydrogen.

Description

technical field [0001] The invention belongs to the technical field of hydrogen elimination and explosion protection, and in particular relates to a hydrogen elimination unit. Background technique [0002] In some chemical production processes, hydrogen leakage or a large amount of hydrogen is prone to occur. In a relatively closed environment, when hydrogen reaches a certain concentration, it will cause an explosion accident. For example, in the passive hydrogen recombiner of the containment of a nuclear power plant, it is necessary to install a hydrogen elimination catalyst filter box to alleviate the risk of explosion caused by the accumulation of hydrogen in design basis accidents or severe accidents, and to prevent hydrogen leakage or generate a large amount of The elimination of hydrogen in the environment of high temperature, high pressure, high humidity and hydrogen content of 1-4% in a relatively closed space of hydrogen. In the prior art, there is generally no hyd...
