Secondary gas filling station

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...

AI Technical Summary

Problems solved by technology

[0028] The disadvantages of the above two types of sub-gas stations are: a large number of equipment, complex operation, huge mechanical loss, large cost of employing more people, and large floor area, especially the skid body compressor and skid body hydraulic pump are expensive and the investment is huge

[0033] There are also people who install the above-mentioned equipment such as compressors or hydraulic pumps in the container to form a small gas filling station, but the disadvantage is that there is no way to lift the container to make it very easy to move, so it can only be fixed at that location, and the source of gas is still gas bottle trailer to inflate it
