Sequence disc system for hydrogen refueling station and use method thereof

Abstract

The invention discloses a sequence disc system for the hydrogen refueling station. The sequence disc system for the hydrogen refueling station comprises a high-pressure hydrogen storage bottle set, a medium-pressure hydrogen storage bottle set, a low-pressure hydrogen storage bottle set, a main gas inlet pipeline, a first branch pipeline, a second branch pipeline and a third branch pipeline, wherein the first branch pipeline, the second branch pipeline and the third branch pipeline are communicated with the main gas inlet pipeline, the second branch pipeline is provided with a medium-pressure control valve, and the third branch pipeline is provided with a low-pressure control valve. A first pressure transmitter is mounted on the high-pressure hydrogen storage bottle set, a second pressure transmitter is mounted on the medium-pressure hydrogen storage bottle set, and a third pressure transmitter is mounted on the low-pressure hydrogen storage bottle set. The sequence disc system for the hydrogen refueling station further comprises at least one hydrogen refueling machine, and a hydrogen refueling machine pressure transmitter is mounted on each hydrogen refueling machine. The sequence disc system for the hydrogen refueling station further comprises a control unit, wherein the control unit is electrically connected with the medium-pressure control valve and the low-pressure control valve and further electrically connected with the first pressure transmitter, the second pressure transmitter, the third pressure transmitter and the hydrogen refueling machine pressure transmitters, and through the arrangement of the control valves and the pressure transmitters, the hydrogen refueling efficiency can be improved, and use of a back pressure valve is avoided.

Description

technical field [0001] The invention relates to the technical field of equipment for hydrogen refueling stations, in particular to a sequential disk system for hydrogen refueling stations and a method for using the same. Background technique [0002] A hydrogen refueling station refers to a place that provides fuel to hydrogen refueling vehicles in the form of hydrogen. Hydrogen gas is generally transported to the hydrogen refueling station by a hydrogen tank truck, and then compressed by the compressor unit, and then distributed and stored in high, medium and low pressure hydrogen storage bottles in order of priority through the sequence control panel. The existing sequence control panel generally uses The form of back pressure valve, that is, back pressure valves are installed on the intake pipelines of high, medium and low pressure hydrogen storage bottles, and different back pressure valves are set with different pressures so that the gas can pass through; among them, th...

AI Technical Summary

Problems solved by technology

After long-term use, the pressure control of the back pressure valve will be unstable. In this way, once the form of mechanical control fails, the function of priority filling will also lose its meaning; and the cost of the hydrogen high pressure back pressure valve is very expensive; The cost is also relatively high

[0006] 2. If the hydrogenation station has 2 hydrogenation machines or more, it is impossible to monitor the pressure value of each hydrogenation machine and the hydrogenation vehicle, and it is impossible to realize the priority hydrogenation control
