technical field [0001] The invention relates to an experimental method and device for combustion experiment simulation and prevention and control, in particular to a comprehensive experimental device for fire simulation and prevention and control of hydrogen energy vehicles and its experimental method, experimental method and device. Background technique [0002] Hydrogen, as a highly clean and environmentally friendly renewable energy, has attracted worldwide attention. , among which hydrogen fuel cell vehicles and related industries are developing rapidly. However, hydrogen is flammable and explosive, has a large diffusion coefficient and low ignition energy, and there are certain risks of leakage, fire and explosion during the use of fuel cell vehicles.

AI Technical Summary

Problems solved by technology

At present, most of the research on the leakage and diffusion of high-pressure gaseous hydrogen and fire characteristics are small-scale experimental devices with simple nozzles and a single pipeline, which cannot effectively and truly simulate the hydrogen leakage fire accident scene of hydrogen fuel cell vehicles, and the existing The operating pressure of the high-pressure hydrogen storage system of most experimental devices is relatively low, which is quite different from the working pressure of the 35MPa-70MPa on-board high-pressure hydrogen storage system of a real hydrogen fuel cell vehicle. As a result, the existing research results cannot reflect the real accident scene well.

In addition, at this stage, there is no comprehensive experimental method and device for studying the fire characteristics and prevention and control technology of high-pressure hydrogen leakage of hydrogen energy vehicles.
