Distributed passive hydrogen safety protection system

Abstract

The invention discloses a distributed passive hydrogen safety protection system, comprising an active hydrogen concentration monitoring system and a passive hydrogen concentration control system. The passive hydrogen concentration control system comprises a housing, and an air entraining zone, a catalytic zone and an air guide zone which are successively distributed in the housing from down to top, wherein the air entraining zone employs an inner trapezoid design, and is used for entraining external hydrogen and air; the catalytic zone employs a Pt or Pd material as a catalyst, and is used for mixing hydrogen, air and catalysts to realize passive catalytic reaction; the air guide zone is used for discharging residual air after catalysis and generated steam. The active hydrogen concentration monitoring system is used for monitoring the concentration of hydrogen introduced into the air entraining zone, and controlling the amount of hydrogen entering the air entraining zone. In accidents of hydrogen leakage, hydrogen blast, etc., the distributed passive hydrogen safety protection system can automatically and passively perform hydrogen safety protection without artificial additional active control, not only greatly improve hydrogen place safety, but also meet different place demands on hydrogen safety protection.

Description

technical field [0001] The invention relates to a protection system, in particular to a distributed passive hydrogen safety protection system and an implementation method. Background technique [0002] Facing the pressure of the energy crisis and the rapid rise of energy prices, the call for alternative energy sources is getting louder and louder. Hydrogen energy, as an efficient and clean energy source, has attracted great attention from countries and scientific research institutions around the world. The concept of hydrogen energy economy has also This surfaced. [0003] The hydrogen energy economy can be understood as a clean economy based on clean energy such as hydrogen energy. It is a hydrogen energy research and development, production, storage, transportation, and operation that takes full advantage of the superior properties of hydrogen energy and targets human needs and markets. , management and other economic activities in general. The development of hydrogen en...

However, these standards and measures usually respond to hydrogen-related accidents by man-made and active control methods, and do not consider the deterioration and escalation of hydrogen-related accidents before and during the implementation of man-made active control in low-probability situations. possibility of

Moreover, because hydrogen is not widely used at present, most users are not experienced enough, and there are also major problems in the acceptable psychology of users.
