Integral liquid gas station system and its operation method

Abstract

The invention relates to an integral liquefied gas filling station system and an operation method thereof. The system comprises a chassis and a receiving tank body which are matched; the receiving tank body is provided with a gas outlet valve and a filling valve connected with a liquefied gas tank ; the other end of the gas outlet valve is connected with a compressor, and the other end of the compressor can be connected with the liquefied gas tank vehicle; the receiving tank body is also provided with a liquid outlet valve; a first emergent cut valve of the liquid outlet valve is connected with a pressure pump, and the output end of the pressure pump is connected with an air entrained gun; a control handle of the first emergent cut valve is in driving connection with a second emergent cut valve; the other end of the second emergent cut valve is connected with a nitrogen bottle; the operation method comprises a liquefied gas filling process and an air entrainment process for vehicles of users; the system adopts a integral chassis structure, has the advantages of simple and convenient extension and high working efficiency, can solve the contradiction of difficult air entrainment in short period, and is favorable for accelerating the popularization and application of clean liquefied gas fuel; and the system is provided with an alarming probe, an alarm instrument and a safety valve, and has more reliable safety.

Description

Technical field [0001] The invention relates to the technical field of liquefied gas refueling station systems, in particular to an integral liquefied gas refueling station system and an operation method thereof; it can be managed through remote monitoring, which is beneficial to accelerate the use of liquefied clean gas in urban vehicles, and can effectively improve The air quality of the city. Background technique [0002] With the process of urbanization in my country, the number of various automobiles has increased sharply. How to reduce the impact of automobile exhaust emissions on the surrounding air quality has also attracted more and more attention. At present, many cities have adopted the promotion of the use of some clean energy sources, such as liquefaction. Petroleum gas, high-pressure natural gas, etc., these clean energy sources have indeed played a certain role in promoting urban environmental protection. [0003] However, the effect of the current promotion is not...

Problems solved by technology

This design adopts the high-pressure hydraulic pump filling method when filling the gas storage cylinders in the station, so the overall gas pressure of the gas station is relatively high, and the compression ratio of natural gas is relatively large. The higher the pressure, the more potential safety hazards for flammable gases. ; Or to ensure the safety of the entire gas station, the design structure must be more reliable and complex, which is not conducive to the promotion of popularization and the shortening of the construction time limit; although the design can detect the liquid level in stock, it does not have a remote control function , which is limited to the perception of insufficient storage; and the entire gas station is not equipped with a leak detection device, once the natural gas leaks, it will cause great disadvantages to the entire gas station, and even a major accident
