Gas supply device of gas station

Abstract

The invention discloses an gas supply device of an gas station. The gas supply device comprises a unloading platform, wherein one side of the unloading platform is provided with a unloading hose I, the unloading platform is connected with a gas storage tank, the gas storage tank is connected with a plunger pump, the plunger pump is connected with a high-pressure purifier, the high-pressure purifier is connected with a sequence control disc, the sequence control disc is sequentially connected with a gas storage device, a gas selling machine, a discharging gas recycling device and a pressurizingmachine, the pressurizing machine is connected with a gas discharging column, and a unloading hose II is arranged on one side of the gas discharging column; an intelligent monitoring device is arranged on the gas selling machine, a low-temperature stop valve is arranged between the unloading platform and the gas storage tank, a ball valve is arranged between the high-pressure purifier and the sequence control disc, and check valves are arranged between the sequence control disc and the gas storage device, between the sequence control disc and the gas selling machine, between the sequence control disc and the discharging gas recycling device, and between the sequence control disc and the pressurizing machine. The gas supply device has the beneficial effects that the equipment utilization rate of the gas station is improved, the economic benefit is increased, and the important social benefit is increased.

Description

technical field [0001] The invention relates to the field of gas filling station equipment, in particular to a gas supply device for a gas filling station. Background technique [0002] The use of gasoline or diesel as motor vehicle fuel will produce a large amount of vehicle exhaust, and the resulting environmental pollution problem has become more and more prominent. As a clean energy source, natural gas is an ideal alternative fuel for vehicles. Natural gas for vehicles includes two forms of CNG (compressed natural gas) and LNG (liquefied natural gas). For this reason, there are CNG filling stations, LNG filling stations and LCNG (liquefied, compressed natural gas) filling stations and other types of vehicle filling stations. . The basic principle of the LCNG gas filling station is to transport LNG from the LNG gas source station to the LCNG gas filling station by LNG tank truck or LNG tank container truck, store it in the LNG storage tank after unloading, and then use ...

AI Technical Summary

Problems solved by technology

Such as LCNG low-temperature valves, LCNG plunger pumps or LCNG high-pressure vaporizers and other equipment are mostly imported products. Once these equipment fails, the replacement and maintenance period is relatively long. Some imported products may require foreign suppliers to repair on site, such as LCNG plunger pump, which will cause the LCNG filling station to have to stop running for a long time. At the same time, when the equipment in the LCNG filling station is discharging sewage, it is often discharged together with part of the LCNG gas, resulting in waste of LCNG gas, and there are certain safety hazards
