Description

technical field [0001] The invention relates to the technical field of pressure equipment testing, in particular to a portable high-pressure hydrogen booster device and method with self-cooling function. Background technique [0002] With the depletion of fossil energy and people's increasing concern about environmental issues, hydrogen energy, which is an important secondary energy source in the new century, is developing rapidly. Hydrogen-powered hydrogen vehicles have become one of the future development directions of the world's automobile industry, which has also led to the development of its key components, vehicle-mounted hydrogen storage cylinders. In order to verify the safety performance of vehicle-mounted hydrogen storage cylinders in the event of accidental fire or collision, the relevant standards of various countries in the world require that the vehicle-mounted hydrogen storage cylinders be filled with high-pressure hydrogen to their nominal working pressure (...

AI Technical Summary

Problems solved by technology

[0003] At present, it is difficult for the existing domestic high-pressure hydrogen booster devices to reach a high level in terms of portability and rapid boosting

Usually portable hydrogen booster has a small output flow rate, slow boost and low output pressure; while a hydrogen booster that can achieve rapid boost is often complicated in equipment, inconvenient to carry, and even requires a heat exchanger, costing higher

Chinese patent 200710011909.7 provides a continuous hydrogen delivery equipment, which uses hydrogen storage materials to achieve dual functions of pressurization and hydrogen purification, but the maximum output pressure is only 35MPa, and a heat exchanger is required so that the equipment is more complicated

Chinese patent 200520046789.0 provides a small hydrogen boosting device, which also realizes hydrogen boosting through the hydrogen charging and discharging characteristics of hydrogen storage materials, but it is only suitable for hydrogen boosting occasions that require high boosting ratio and low flow rate

Chinese patent 201110119297.X provides a complete set of rapid hydrogen charging equipment and method based on gas-driven booster technology, which can realize rapid charging and discharging of high-pressure hydrogen storage cylinders by pre-increasing hydrogen storage tanks, gas-driven booster pumps and other equipment , but its equipment and control system are more complicated and not portable
