A multi-stage filter type natural gas compressor

Abstract

The invention discloses a multistage filtering type natural gas compressor which comprises a first filtering device, a cylinder, a second filtering device, a cleaning solution storage tank, a first three-way valve, a gas storage device and a control module, wherein the first filtering device comprises a first suction pump, a first inlet pipe, a first outlet pipe, a first shell, a first filter element, a first spherical shower nozzle, a first fan and the first three-way valve; the second filtering device comprises a second suction pump, a second inlet pipe, a second outlet pipe, a second shell, a second filter element, a second spherical shower nozzle, a second fan and a second three-way valve. According to the multistage filtering type natural gas compressor, uncompressed gas is filtered to be purified by the first filtering device, and the compressed gas is filtered to be further purified and compressed by the second filtering device.

Description

technical field

[0001] The invention relates to the technical field of compressors, in particular to a multi-stage filtering type natural gas compressor. Background technique

[0002] Whether it is town gas or motor vehicle gas, due to various reasons, there are always many micron impurities in natural gas, mainly due to incomplete desulfurization, dehydration, and dust removal of the natural gas parent station and corrosion of the tank carrying the natural gas. The existence of impurities affects In order to ensure the smooth operation of natural gas consumption equipment, natural gas filters are often installed at the last station that provides gas sources to users. For the convenience of natural gas transportation, the natural gas obtained by users needs to be compressed.

[0003] At present, natural gas is mostly filtered before compression, which cannot ensure the purity of compressed natural gas, and the filter device has a complicated structure and is difficult to cl...
