Description

technical field [0001] The invention belongs to the technical field of a hydrogen gas discharge system for a hydrogen filling station, and in particular relates to a safe and reliable multifunctional hydrogen gas discharge system. Background technique [0002] As a large industrial country, China is also the country with the largest number of motor vehicles in the world. It produces a large amount of greenhouse gases in industrial production and transportation, which is not conducive to the goal of reducing carbon emissions that China promised to the world. development is gaining more and more attention. With the development of science and technology, the advent of hydrogen fuel cell vehicles will help the country fundamentally reduce the continuously increasing carbon emissions. The core power of a hydrogen fuel cell vehicle is a hydrogen fuel cell, which is a power generation device that directly converts the chemical energy of hydrogen and oxygen in the air into electric...

Problems solved by technology

However, in the process of connecting the tube bundle trailer to the compressor or pressure vessel, it is mostly connected by a hydrogen delivery pipeline composed of several simple components such as connecting hoses, high-pressure pipelines, safety valves and ball valves. The structure is relatively simple, mostly because hydrogen The refueling station is an emerging energy station, and there are very few hydrogen refueling stations built in China.

However, in the process, if there is hydrogen leakage or an unknown fire source, it is impossible to monitor and alarm the shutdown, it is impossible to count the mass flow rate of hydrogen delivery, it is impossible to stop the unknown impurities in the gas source in time, it is impossible to carry out hydrogen sampling and analysis, and it is unavoidable. The connecting hose breaks when the long-tube trailer accidentally slips, and the pipeline cannot be purged and replaced during pipeline maintenance. At the same time, it does not have anti-static and alarm functions.
