Recycling device for sub-high-pressure natural gas

The utility model relates to the technical field of natural gas recovery, and discloses a sub-high-pressure natural gas recovery device which comprises a compressor, a power mechanism and a high-pressure gas storage tank vehicle, a gas inlet pipe and a gas outlet pipe are connected to the compressor, a balance section is arranged on the gas inlet pipe, the gas outlet pipe is communicated with the high-pressure gas storage tank vehicle, and the power mechanism provides power for the compressor. The problem that when existing domestic province and city branch lines, gas company branch lines, urban gas valve chambers and tube well natural gas supply pipelines are overhauled, natural gas in overhauled pipe sections is directly exhausted into air, and economic losses are caused is solved. 本实用新型涉及天然气回收技术领域，公开了次高压天然气的回收装置，包括压缩机、动力机构和高压储气罐车，压缩机上连接有进气管和出气管，进气管上设有平衡段，出气管与高压储气罐车连通，动力机构给压缩机提供动力，以解决国内现有省市支线、燃气公司支线、城镇燃气阀室、管井天然气供气管道检修时，存在因将检修管段内的天然气直接排入空气中，造成经济损失的问题。
