The invention discloses a vehicle-mounted high-pressure hydrogen graded filling system. The vehicle-mounted high-pressure hydrogen graded filling system comprises two metal diaphragm type compressors,a high-pressure gas storage tank, a low-pressure gas storage tank, two flow control valves, a vapor compression type refrigerating system, a hydrogenation machine and a vehicle-mounted hydrogen storage bottle. The vapor compression type refrigerating system is composed of an evaporation heat exchanger, a compressor, a condenser and a throttling valve and used for reducing the temperature of the high-low pressure hydrogen storage tank. The two metal diaphragm type compressors are correspondingly connected with the high-pressure gas storage tank and the low-pressure gas storage tank, outlets ofthe high-pressure gas storage tank and the low-pressure gas storage tank are correspondingly connected with the hydrogenation machine through the flow control valves, and a pressure gauge and a temperature gauge are arranged on a connecting pipeline, and the vehicle-mounted hydrogen storage bottle is connected to the other end of the hydrogenation machine. The evaporation heat exchanger is correspondingly connected with the high-pressure gas storage tank and the low-pressure gas storage tank and provides a heat exchange or refrigeration function for the gas storage tanks. Selection can be carried out according to actual conditions such as extreme pressure, and a theoretical basis is provided for specific implementation of the vehicle-mounted high-pressure hydrogen filling system.
Description
technical field [0001] The invention relates to a hydrogen fuel cell vehicle, in particular to a hydrogen precooling and hierarchical filling system for a vehicle-mounted hydrogen storage cylinder, and belongs to the scientific field of new energy utilization. Background technique [0002] Hydrogen energy is a new energy with large reserves, high energy density and cleanness, and it is an important direction for the development of low-carbon energy utilization in the future. Vigorously developing the hydrogen energy industry, including hydrogen production, hydrogen storage, hydrogen energy utilization and other industrial chains, has become an important development direction that countries around the world prioritize in energy planning. At present, fuel cell is the most mature technology for large-scale utilization of hydrogen energy. Since around 2011, my country has begun to develop hydrogen fuel cell technology, and has achieved rapid development in recent years. Many reg...
