Residual gas recovery system of gas station compressor

Abstract

The invention relates to a residual gas recovery system of a gas station compressor. The residual gas recovery system is simple in equipment and evident in effect. On the basis of existing technologies, a residual gas recovery system body is added, the residual gas recovery system body comprises a recovery pipe, and a check valve, a gas-liquid separator, a pressure regulating stabilizer and the like which are arranged on the recovery pipe. The recovery pipe is indirectly connected onto high-pressure pipes corresponding to the number of recovery branch pipes in a pressure regulating metering system. A by-pass pipe is further arranged on the recovery pipe, a starting end of the by-pass pipe is connected onto a pipeline between a first ball valve and a second ball valve of the recovery pipe, a tail end of the by-pass pipe is connected onto a pipeline between a third ball valve of the recovery pipe and the recovery branch pipes, and a by-pass valve is arranged on the by-pass pipe. The residual gas recovery system of the gas station compressor has the advantages that since a residual gas discharging part of a conventional gas station compressor is improved, recycling of residual gas of the compressor is achieved, natural gas is recycled, and accordingly manufacturing cost of an enterprise is saved, environmental destruction is avoided, and effect of energy conservation and emission reduction is achieved.

Description

technical field [0001] The invention relates to the field of natural gas equipment, in particular to a gas station compressor residual gas recovery system. Background technique [0002] Natural gas is a clean and environmentally friendly high-quality energy source, which contains almost no sulfur, dust and other harmful substances. It produces less carbon dioxide than other fossil fuels when burned, resulting in a lower greenhouse effect. Relatively speaking, it is cleaner and more environmentally friendly than gasoline. Fundamentally improve environmental quality. At present, residents start to use natural gas for cooking and automobile energy, so the scale of natural gas companies is gradually expanding, and it involves the supply of residential gas and natural gas for vehicles. At present, gas vehicles are refueled through gas stations, and gas stations All the gas is stored in the gas storage cylinder group. Once the gas in the gas storage cylinder group decreases, it i...

AI Technical Summary

Problems solved by technology

Generally speaking, for the purpose of environmental protection, the number of natural gas vehicles is increasing. The establishment of new gas filling stations and corresponding equipment makes more and more natural gas discharged as residual gas every day, which will not only have a certain impact on the environment, but also The important thing is that it will cause great waste and cause considerable losses to the enterprise.
