Abstract

The invention relates to an active safety protection system and method for hydrogen leakage. The active safety protection system for hydrogen leakage can be applied to the hydrogen transporting and storing process, and can effectively and actively prevent the problem of ignition or explosion caused by hydrogen leakage. According to the active safety protection system for hydrogen leakage, leaked hydrogen is collected through a collecting chamber, and the equivalent weight of the hydrogen in the collecting chamber is detected in real time through a detection device. An active protection deviceis used for taking active safety protection measures when the equivalent weight of the hydrogen reaches to a preset hydrogen equivalent weight threshold value, so that hydrogen in the environment is not accumulated continuously. The active safety protection system for hydrogen leakage can actively operate the leaked hydrogen, so that the potential safety hazard brought by hydrogen leakage is reduced.

Description

technical field [0001] The present application relates to the technical field of hydrogen energy, in particular to an active safety protection system and method for hydrogen leakage. Background technique [0002] With the massive exploitation and use of traditional fossil energy, the problems of energy depletion, climate change and ecological environment have become increasingly prominent. However, the unevenness and intermittency of renewable energy will cause a huge impact on the grid after grid connection, so energy storage technology is very important. Among numerous energy storage technologies, hydrogen energy has obvious advantages due to its high energy density, renewability and cleanliness. [0003] However, hydrogen is an extremely flammable and explosive gas. When the volume fraction of hydrogen in air exceeds 4%-75%, it can cause an explosion when it encounters a fire source. During the transportation and storage of hydrogen, the leakage of hydrogen is unavoidab...
