Abstract

The invention relates to the technical field of hydrogen leakage monitoring and protecting, in particular to a hydrogen energy power generation device hydrogen leakage monitoring and protecting deviceand method. According to the hydrogen energy power generation device hydrogen leakage monitoring and protecting device and method, an air extraction cover is arranged over each valve of a hydrogen energy power generation device to collect hydrogen leaking from the valve; a preset number of branch pipelines are used for gathering collected hydrogen to a local pipeline, a hydrogen concentration testing instrument and a sound and light alarm device arranged in the local pipeline are utilized for monitoring the hydrogen concentration, and an alarm is given when the standard is exceeded; and the communication position of the local pipeline and a main pipeline is provided with an electromagnetic valve, opening and closing of the electromagnetic valve are controlled according to the hydrogen concentration and the standard exceeding situation in the local pipeline, and finally, the main pipeline is used for exhausting hydrogen into air. According to the provided hydrogen energy power generation device hydrogen leakage monitoring and protecting device and method, simpleness and practicability are achieved, sensitivity is high, and the fire disaster, explosion and other accidents caused byhydrogen concentration standard exceeding can be effectively prevented.

Description

Technical field [0001] The present application relates to the technical field of hydrogen leakage monitoring and protection, and in particular to a hydrogen leakage monitoring and protection device and method for a hydrogen energy generating device. Background technique [0002] Hydrogen power generation refers to the use of hydrogen and oxygen to burn to form a hydrogen-oxygen generator set. This kind of unit is a rocket-type internal combustion engine structure with a generator. It does not require a complicated steam boiler system. It has a simple structure, convenient maintenance, and quick start. When the grid is under low load, it can also absorb excess electricity to electrolyze water to produce hydrogen and oxygen for power generation during peak hours. Therefore, hydrogen power generation has been widely used. [0003] Since hydrogen is used for power generation, commonly used hydrogen power generation equipment will monitor the leakage of hydrogen. Hydrogen power gener...
