Hydrogen utilization system and method for hydrogen storage cylinder group of hydrogen refueling station

Abstract

The invention relates to the technical field of hydrogenation, and provides a hydrogen utilization system and method for a hydrogen storage cylinder group of a hydrogen refueling station. The hydrogenutilization system comprises a TT vehicle, a gas unloading cabinet, a hydrogen compressor, a hydrogenation machine, a low-pressure gas storage bottle, a medium-pressure gas storage bottle, a high-pressure gas storage bottle, a first gas valve, a second gas valve, a third gas valve, a fourth gas valve, a fifth gas valve, a sixth gas valve, a seventh gas valve and an eighth gas valve. According tothe hydrogen utilization system and method, multiple working modes are provided, so that the hydrogen refueling station can meet various hydrogen refueling scenes; and when the air pressure of hydrogen in the gas storage bottles is lower than a certain value and the hydrogen cannot be normally injected into a hydrogen energy automobile, the residual hydrogen in the gas storage bottles is pressurized through the hydrogen compressor, so that the residual hydrogen in the gas storage bottles can also be normally injected, and the hydrogen utilization rate of the gas storage bottles is increased.

Description

technical field [0001] The invention relates to the technical field of hydrogenation, in particular to a hydrogen utilization system and method for a hydrogen storage bottle set in a hydrogenation station. Background technique [0002] With the popularity of hydrogen vehicles, the demand for hydrogen refueling stations is increasing. In the prior art, the hydrogen in the hydrogen refueling station is usually provided by the TT car. When the hydrogen in the TT car is insufficient, or the TT car temporarily leaves the hydrogen refueling station, the hydrogen refueling station usually uses the gas storage cylinder group as a temporary gas supply However, when the pressure of the hydrogen in the gas storage cylinder is lower than a certain value, the hydrogen in the gas storage cylinder cannot be normally filled into the hydrogen energy vehicle, resulting in a low utilization rate of the hydrogen in the gas storage cylinder, resulting in a waste of resources. [0003] The above...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to solve the problem that in the prior art, the gas storage cylinder group is used as a temporary gas supply source. When the pressure of hydrogen in the gas storage cylinder is lower than the minimum pressure required for hydrogenation, the hydrogen cannot be normally injected into the hydrogen Energy vehicles, leading to technical problems in the utilization rate of hydrogen in gas storage cylinders is not high
