Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] Such as Figure 1 ~ Figure 3 As shown, the piston-type compressed natural gas sub-station of the non-station gas storage system of the present invention includes a gas filling system formed by sequentially connecting the trailer bottle group 2, the compressor 1 and the gas sales unit 3 through the main pipeline 18, and the trailer bottle group 2 A gas pipeline is connected with the gas sales unit 3 . After the trailer transports the compressed natural gas from the parent station to the substation, the trailer bottle set 2 is directly used as the gas storage tank of the gas sales unit 3 . When adding gas to the car, firstly, the natural gas in the trailer bottle set 2 is directly fed to the car by the gas selling unit 3 through the gas transmission pipeline between the trailer bottle set 2 and the gas sales unit 3. When the pressure cannot be fi...

The invention disclose a non-station use air storage system plunger type compressed natural gas sub-station which can blow an automobile up and can effectively reduce the investment of building a station. The non-station use air storage system plunger type compressed natural gas sub-station comprises an air-entrapping system formed by a trailer bottle group, a compressor and a selling gas machine unit which are sequentially connected by a main pipe. A gas transportation pipe is connected between the trailer bottle group and the selling gas machine unit. The trailer bottle group is communicated with the selling gas machine unit by the gas transportation pipe so that the trailer bottle group can serve as an air storage tank of the selling gas machine unit. The trailer bottle group directly supplies gas to the selling gas machine unit; therefore, the air storage tank is not separately arranged in the system, thus greatly reducing the investment of building the station, in particular to being suitable for popularizing and use in a compressor sub-station air-entrapping system.
Description
technical field [0001] The patent of the present invention relates to a gas filling system, in particular to a piston-type compressed natural gas sub-station system of a non-station gas storage system for filling automobiles. Background technique [0002] At present, in the piston-type compressed natural gas sub-station system, for safety and gas storage needs, two to three high-pressure gas storage tanks of about 2 cubic meters must be installed behind the compressor. After the trailer transports the compressed natural gas from the main station to the substation, the compressor unloads the natural gas in the trailer's gas cylinder into three 2 cubic meter high-pressure gas storage tanks, and then sends it to the gas sales unit to refill the car. High-pressure gas storage tanks are expensive and occupy a large area, so the area when building a station should be increased accordingly, so the cost of building a station will also increase accordingly.
