Embodiment 1

[0132] Only the gas storage device of the technical solution 2 is described, and the gas storage device of the technical solution 1 is similar.

[0133] Technical solution two

[0134] The sub-gas station is composed of a gas dispenser, a priority controller, and a gas storage device. Its technical features are: the gas storage device is composed of multiple 25MPa high-pressure CNG compressed natural gas storage cylinders, and the gas storage device can be made into multiple Tube bundle containers, container analogues or multi-long tube trailers, the whole directly goes to the parent gas filling station to inflate, and after being filled with gas, it is transported back to the child gas filling station and connected to the priority controller to refuel CNG fuel vehicles through the gas dispenser.

[0135] Let's illustrate with an example

Embodiment 2

[0176] Technical solution one

[0177] The sub-gas filling station consists of a filling machine, a priority controller, and a gas storage device to form a whole container or a container-like whole. Its technical characteristics are: the gas storage device is composed of multiple 25MPa high-pressure CNG compressed natural gas storage cylinders. , the gas storage device, gas filling machine, and priority controller form a whole to go directly to the parent gas filling station for filling, and transport it back to various places to directly fill CNG fuel vehicles.

[0178] Here it is emphasized that the sub-gas station consists of a gas dispenser, a priority controller, and a gas storage device (see Figure 4 ) constitutes a whole of a container or the like of a container (for the whole see Figure 8 ), as the working principle of the gas storage device has been described in detail in Embodiment 1, it will not be repeated here.

Embodiment 3

[0196] Technical solution three

[0197] The sub-gas filling station is composed of a filling machine, a priority controller, and multiple gas storage devices. Its technical characteristics are: multiple gas storage devices, each of which is composed of multiple 25MPa high-pressure CNG compressed natural gas storage Composed of cylinders, multiple gas storage devices are connected to the priority controller and under its control, the CNG fuel vehicle is refueled through the gas dispenser. When the previous gas storage device runs out of CNG compressed natural gas, the next gas storage device needs to provide high pressure. CNG compressed natural gas, after the last gas storage device runs out of CNG compressed natural gas, go to the parent gas filling station to inflate, transport it back to the sub gas filling station and connect it with the priority controller, and use it as the next gas storage device of this round for the previous gas storage The device (the next gas stora...

Abstract

The invention relates to a brand-new branch gas station, only consisting of a gas adding machine, a priority sequence controller and a plurality of gas storage devices. The branch gas station has the technical characteristics that each gas storage device is composed of a plurality of gas tanks which are filled with high pressure compressed natural gas (CNG) of 25 MPa, the gas storage devices alternatively and cyclically provide high pressure CNG to form alternate recycle high pressure technology, solving the problem that the gas storage devices need a compressor or a hydraulic pump sell the remaining gas by pressurization, saving the massive equipment investment such as compressor, hydraulic pump, intra-station gas tank group and the like and easily standardizing the three major components: the gas adding machine, the priority sequence controller and the gas storage devices, being free from daily consumption such as power supply, mechanical wear and the like; in addition, the branch gas station is matched with a major gas station and pursues the technical road featuring L-CNG and is easily and rapidly replicated in cities throughout the country, thus enjoying the possibility of changing the backward situation at home where for the past dozens of years, CNG stations are hard to be integrated into a complete sales network.

Description

technical field [0001] The invention is applicable to various gases. Involving the method and equipment for establishing a sub-gas filling station, taking compressed natural gas (CNG) as an example, the specific point is to use a gas storage device loaded with compressed natural gas CNG from the parent station to connect the sub-gas filling station with a priority controller through gas filling The machine refuels cars using CNG fuel. Background technique [0002] In order to use compressed natural gas (CNG) as fuel for automobiles, the conventional method is to form a sales network in the form of "child-mother stations" to refuel automobiles. [0003] The function of the parent gas filling station is to take gas from the natural gas transmission pipeline, after pressure regulation, metering, and dehydration, enter the compressor to boost the pressure, and then go to the gas storage cylinder group in the station, go through the priority control system to the gas dispenser f...
