Embodiment Construction

[0019] Such as figure 1 As shown, the specific example of the inflation system of the device for recovering residual natural gas includes: a long tube trailer 110, a gas vending machine 120, a compression tank 130, an oil storage tank 140, a controller 150, a natural gas supply pipe 160, an oil delivery pipe 170, and an oil return pipe 180, Pressure sensor 133, oil level sensor 131, pump 141 and multiple safety valves v161, v162, v163, v171, v181.

[0020] First, the gas-filled long-pipe trailer 110 is used as a mobile tool, and its multiple high-pressure natural gas containers 111 are connected to each other by gas pipes 112 and installed on guide rails, making the movement of compressed natural gas possible.

[0021] In order to discharge the compressed natural gas stored in the gas pipe 112, a discharge port 114 connected to a gas pipe safety valve 113, a gas pipe controller (not shown) and an external natural gas supply pipe 160 is installed.

[0022] The following gas ve...

Abstract

The present invention relates to a gas-filling system having a residual-gas recovery device and to a residual-gas recovery method for minimising the amount of residual gas remaining in a tube trailer, and more particularly residual gas remaining in a tube trailer (110) is recovered into a feeding tank (130) by means of the natural pressure difference, and then the recovered residual gas is hydraulically compressed and reused, thereby minimising the amount of residual gas remaining in the tube trailer (110) and consequently making it possible to expect the filling efficiency to be maximised and transportation costs to be minimised.

Description

【Technical field】 [0001] The invention relates to an inflation system and a method for recovering residual natural gas with a device for recovering residual natural gas. The main content of the invention is to maximize the use of long-tube trailers to replenish the remaining compressed natural gas due to insufficient pressure after the vehicle is replenished, so that the residual compressed natural gas in the long-tube trailer reaches min. 【Background technique】 [0002] Recently, with the rapid development of industrialization and the increase of national income, life has become more convenient, and living standards have also been continuously improved. The consumption of chemical fuels has shown a geometric growth trend due to this influence. However, the ensuing environmental pollution has gradually risen and evolved into a serious social problem. In particular, automobiles known as "the flower of modern civilization" have also become the main cause of air pollution due ...
