The specific principle of the application is as follows:
when combustible gas (such as hydrogen) leaks in the system and the combustible gas leakage detector detects that the content of the combustible gas in the air reaches a set alarm value (such as the content of the hydrogen reaches 0.4 percent VOL, namely the concentration of the hydrogen set in the central control system is 10 percent LEL), the central control system transmits the hydrogen to a man-machine interaction unit of an industrial control screen for displaying and enables an audible and visual alarm system to alarm;
when the combustible gas leakage detector detects that the content of combustible gas in the air reaches a set alarm value (if the content of hydrogen reaches 1% VOL, namely when the concentration of hydrogen set in the central control system is 25% LEL), the combustible gas diffusion pipeline is opened in a linkage manner (by the aid of the controllable valve system), and dangerous gas (such as hydrogen) in the system is safely discharged into the air along the diffusion pipeline.
