Description

technical field [0001] The invention relates to the field of hydrogenation stations, in particular to a 70MPa large-flow hydrogenation system. Background technique [0002] Hydrogen energy is recognized as clean energy, and the calorific value of hydrogen is the highest among common fuels, about 3 times that of oil and 4.5 times that of coal. Therefore, hydrogen energy vehicles can reduce air pollution, reduce greenhouse gas emissions and reduce the consumption of traditional energy sources. Dependency and other aspects have outstanding advantages. [0003] With the gradual rise and large-scale application of hydrogen fuel cell vehicles, as a supporting facility for hydrogen fuel cell vehicles, the construction of hydrogen refueling stations is also accelerating. According to my country's development of fuel cell vehicle routes, the main goal is to achieve electrification of the transportation sector. According to the "New Energy Vehicle Industry Development Plan (2021-203...

Problems solved by technology

[0009] (4) Hydrogenation hose: The inner diameter of the currently available hose is too small, and the hose is the weakest point of erosion and abrasion resistance for high-flow filling, which becomes the key bottleneck of high-flow filling, and a large inner diameter that is not too hard is designed Hoses face enormous challenges;

[0010] (5) Micro-channel heat exchanger: The selection and design of high-pressure and large-flow micro-channel heat exchangers is the key to avoiding bottlenecks. Currently, safe and reliable large-flow micro-channel heat exchangers cannot be selected on the market
