High-pressure hydrogen supply system of external hydrogen supply hydrogen refueling station

Abstract

The invention provides a high-pressure hydrogen supply system for an external supplying type hydrogen filling station, which can fill hydrogen fuel for fuel cell powered vehicles. The hydrogen supply system mainly comprises a pipe bundle hydrogen conveying vehicle, a fixed high-pressure hydrogen storage tank group, a parallel multi-compressor pressurizing system, a high-pressure hydrogen filling system, and a data acquiring, processing and safety monitoring system. The high-pressure hydrogen supply system takes the pipe bundle hydrogen conveying vehicle as a part of a hydrogen storage container of the hydrogen filling station and makes the pipe bundle hydrogen conveying vehicle a first stage of the staged hydrogen storage container, adopts the pressurizing system consisting of multiple compressors which are connected in parallel, and introduces the data acquiring, processing and safety monitoring system. The high-pressure hydrogen supply system has the advantages of adjustable hydrogen storage volume, large operation flexibility, cost conservation, convenient maintenance, high service efficiency and so on.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to an external hydrogen refueling station that integrates hydrogen transportation, storage, compression, filling, data acquisition, processing and safety monitoring, and can provide high-pressure hydrogen filling for fuel cell vehicles. High pressure hydrogen supply system. Background technique [0002] A series of problems such as air pollution, energy shortage, and climate warming force human beings to vigorously develop new energy utilization technologies. Because hydrogen has the advantages of wide sources, good recyclability, and environmental friendliness during use, fuel cell vehicle technology using hydrogen as fuel has become a research and development hotspot for governments and major energy and automobile companies. In recent years, fuel cell vehicle technology has become more and more mature, and various prototype vehicles have been launched one after another. Demonstr...

Problems solved by technology

The biggest drawback of the two methods is that it is difficult to balance the operational flexibility of the refueling capacity with the economics of the hydrogen refueling station

[0005] In the demonstration operation stage of fuel cell vehicles and even the initial stage of commercial operation, the number of fuel cell vehicles is limited. In order to meet the demand for high-pressure hydrogen during the peak refueling period, if the first mode above is adopted, a higher hydrogen storage capacity needs to be designed. , which means that the hydrogen refueling station needs to be equipped with more high-pressure hydrogen storage bottles, which will greatly increase the cost of station construction, instead of filling peak hours, which will result in low utilization of hydrogen storage bottles and reduce the economy of the entire hydrogen refueling station; In the second mode mentioned above, the hydrogen refueling station needs to be equipped with a large-displacement hydrogen compressor, which will greatly increase the purchase cost of the compressor in the hydrogen refueling station, and the frequent start and stop of the compressor during the refueling process is not conducive to its stable operation, and will increase the cost of the compressor. operating and maintenance costs
