Abstract

The invention discloses a private garage hydrogen leakage simulation test device and test method, and belongs to the technical field of hydrogen safety utilization. The device comprises a garage system, a high-pressure hydrogen discharge system, a high-sensitivity hydrogen concentration sensor, a concentration sensor support system and a nozzle base system. The hydrogen leakage direction is controlled through a high-precision lifting table and a high-precision rotating table, and the size of the nozzle is adjusted through sprayers with different hole diameters. The device is suitable for testing the hydrogen concentration field after high-pressure hydrogen leakage at different angles, and the high-pressure hydrogen release angle is adjustable so that the hydrogen concentration distribution after high-pressure hydrogen leakage in a garage under different conditions is tested, and the danger is evaluated.

Description

technical field [0001] The invention relates to the technical field of hydrogen safety, in particular to a hydrogen leakage simulation test device and an experimental method in a private garage. Background technique [0002] As people's demand for energy continues to increase, while traditional energy sources such as oil are increasingly depleted, the energy crisis is becoming increasingly severe. And the combustion of traditional energy causes a lot of environmental pollution, greenhouse gas effect and acid rain effect, so it is urgent to develop green alternative energy to alleviate the crisis of traditional energy. Since the product of combustion is water and has no pollution, hydrogen energy has aroused a research boom all over the world, especially the research on hydrogen fuel vehicles. According to the "Blue Book on the Development of China's Hydrogen Energy Industry Infrastructure", by 2030, there will be 2 million fuel cell vehicles and 1,000 hydrogen refueling sta...
