The vehicle mounted integrated skid-mounted CNG pressure reducing gas supply station adopts integrated skid-mounted CNG pressure reducing equipment, which integrates a pressure reducing system, gas storage system, heat tracing system, and control system, and can support a gas supply capacity of 500 Nm3/h. It can be used with a bottle group type skid mounted gas storage device with a gas storage capacity of 400 standard cubic meters, or a CNG long tube trailer with a gas storage capacity of 4000 standard cubic meters, which can meet the cooking and heating gas needs of 200 households.
The vehicle mounted integrated skid-mounted CNG decompression gas supply station is operated and controlled through an unattended platform system, which includes three parts: the CNG decompression equipment operation monitoring subsystem, the vehicle mounted storage tank natural gas parameter monitoring subsystem, and the station video monitoring subsystem. The operation monitoring system of the CNG decompression equipment automatically controls the decompression equipment and bottle group type skid mounted gas storage equipment through the PLC control system in the CNG decompression equipment. It can be remotely transmitted to the dispatching center through wired broadband or 3G wireless broadband, which can display the operating conditions of the equipment in the dispatching center and monitor the operation of the CNG decompression equipment in real time. The station video monitoring system monitors the equipment and the surrounding environment of the station in real time, and can be remotely transmitted and displayed in the dispatching center. The on-board storage tank natural gas parameter monitoring system displays the position of the CNG trailer and the temperature and pressure of the CNG in the tank in the dispatching center through Beidou GPS equipment and temperature and pressure acquisition equipment loaded on the CNG long tube trailer, and monitors the operating status of the CNG trailer in real time.
The vehicle mounted small integrated skid-mounted CNG decompression gas supply station uses integrated skid-mounted equipment, which can save 40% of the overall investment compared to traditional CNG decompression gas supply stations; Equipment manufacturing and station construction are fully implemented in accordance with national standards and industry norms, and real-time monitoring is conducted in cooperation with unattended platform systems, ensuring sufficient safety; The promotion of this skid-mounted CNG decompression gas supply station can promote the utilization of natural gas in rural areas of Beijing and bring clean energy to the vast rural areas.
