Embodiment 1

[0019] Such as figure 1 As shown, this embodiment provides a dual-compressor operation control system for a hydrogen refueling station, including a first compressor 21, a second compressor 22, a pneumatic valve 3, a high-pressure gas cylinder 61, a medium-pressure gas cylinder 62, a low-pressure Gas cylinder 63, pressure sensor 5 and data controller 1. The pneumatic valve 3 is assembled and installed on the pressure distribution regulating box 4, which is convenient for centralized observation and maintenance of the pneumatic valve 3. The gas outlet side of the first compressor 21 and the gas outlet side of the second compressor 22 are connected through pipelines and continue to be connected to the high-pressure gas storage cylinder 61, the medium-pressure gas storage cylinder 62 and the low-pressure gas storage cylinder through the pneumatic valve 3 respectively through the three-way pipeline. 63, the high-pressure gas storage cylinder 61, the medium-pressure gas storage cyl...

Embodiment 2

[0022] The difference between this embodiment and Embodiment 1 is that the data controller 1 is a programmable logic controller, which has high reliability and strong anti-interference ability, and can stably and efficiently control the hydrogen compression gas storage system. Storage operation. The data controller 1 can also be an intelligent mobile terminal, such as a smart phone. The data controller 1 is connected to the pressure sensor 5, the first compressor 21 and the second compressor 22 via a Bluetooth signal, and controls the pneumatic valve 3, the second compressor 22 through the data controller 1. When the first compressor 21 and the second compressor 22 are turned on and off, the data controller 1 monitors the pressure of each gas storage cylinder through the pressure sensor 5, so as to realize the intelligent control of the operation of the two compressors in the hydrogen refueling station. In addition, the signal cable connection between the pneumatic valve 3, th...

Abstract

The invention provides an operation control method for double compressors of a hydrogen refueling station. The air outlet side of the first compressor and the air outlet side of the second compressor are connected with a high-pressure gas storage cylinder, a medium-pressure gas storage cylinder and a low-pressure gas storage cylinder through a pipeline commonly and through different pneumatic valves. The high-pressure gas storage cylinder is connected with a high-pressure inflation pipeline through a pipeline, the medium-pressure gas storage cylinder is connected with a medium-pressure inflation pipeline through a pipeline, and the low-pressure gas storage cylinder is connected with a low-pressure inflation pipeline through a pipeline. The high-pressure gas storage cylinder, the medium-pressure gas storage cylinder and the low-pressure gas storage cylinder are connected with a discharging pipeline through a pipeline. The air inlet side of the discharging pipeline is connected with a pneumatic valve. The pipeline of the air inlet side of each of the high-pressure gas storage cylinder, the medium-pressure gas storage cylinder and the low-pressure gas storage cylinder is connected with a pressure sensor. A data controller is in signal connection with the pneumatic valves, the pressure sensors, the first compressor and the second compressor. The operation control method has the beneficial effects that operation of the double compressors of the hydrogen refueling station can be efficiently controlled in an energy-saving manner, and operation of the double compressors of the hydrogen refueling station can be intelligently controlled.

Description

technical field [0001] The invention relates to the technical field of hydrogen gas storage in a hydrogen refueling station, in particular to a dual-compressor operation control system for a hydrogen refueling station. Background technique [0002] The hydrogen fuel cell working process of hydrogen fuel vehicles can achieve zero emissions, and there is no hydrogen leakage problem. Compared with electric vehicle lithium batteries, the performance is more stable and safe. The technology of the vehicle-mounted hydrogen high-pressure gas storage tank is also mature and has high safety. The hydrogen refueling time of hydrogen fuel vehicles is equivalent to that of gasoline and diesel vehicles, and the cruising range of hydrogen fuel vehicles can reach more than 500 kilometers, which is about twice that of electric vehicles. The hydrogen refueling of hydrogen fuel vehicles needs to be carried out in hydrogen refueling stations, and the country needs to gradually establish a sound...
