Abstract

The invention discloses an alarm system and method for detecting hydrogen leakage, and the system comprises a hydrogen production device which is used for producing hydrogen; a hydrogen compression device which is used for compressing and storing the hydrogen prepared by the hydrogen production device into a high-pressure hydrogen storage device; the high-pressure hydrogen storage device which isused for storing the hydrogen compressed by the hydrogen compression device and conveying the hydrogen to a hydrogen utilization device when the hydrogen utilization device needs to use the hydrogen;the hydrogen utilization device which is used for utilizing hydrogen; a hydrogen safety detection device which is used for detecting the hydrogen leakage condition and transmitting the detection information to an information processing and alarming device; and the information processing and alarming device which is used for processing the detection information and judging whether to give an alarmor not. According to the invention, the hydrogen leakage position can be simply, rapidly and effectively positioned, the alarm information can be conveniently and timely reported to the outside, the possibility that hydrogen leakage is gathered to reach an explosion limit is reduced, and major accidents can be effectively prevented.

Description

technical field [0001] The invention belongs to the field of hydrogen energy equipment, in particular to a hydrogen leakage alarm system and method. Background technique [0002] In recent years, with the rapid development of hydrogen energy preparation, storage and transportation technology, and fuel cell technology, hydrogen energy has been increasingly used in the three major fields of power generation, transportation, and energy storage. In the field of power generation, fuel cells are developing rapidly in the fields of stationary power generation and household cogeneration due to their advantages of cleanness, environmental protection, high efficiency and uninterrupted power generation. In the field of transportation, hydrogen fuel cell vehicles have obvious competitive advantages in the field of medium and heavy trucks due to their advantages of no pollution, high efficiency, high load capacity, fast hydrogen refueling and long battery life, and have become the best s...
