Embodiment Construction

[0022] refer to figure 1 , a natural gas compressor with dehumidification function proposed by the present invention, comprising: a body 1, a first three-way valve 2, a second three-way valve 3, a pressure sensor 4, a first humidity sensor 5, a second humidity sensor 6 and control module. The main body 1 is provided with a compression chamber 101 , a return passage 102 , an exhaust chamber 103 , an air storage chamber 104 , a drying chamber 105 , an air suction passage 106 and an exhaust passage 107 .

[0023] A compression device is provided inside the compression chamber 101 for compressing gas. In this embodiment, the compression device is a piston, the inlet and outlet of the compression chamber 101 and the return channel 102 are located on the same side of the piston, and the piston compresses the gas through reciprocating motion. In practice, the compression device may also use a turbine, and the inlet of the compression chamber 101 and the return channel 102 are locat...

Abstract

The invention provides a natural gas compressor with a dehumidification function. The natural gas compressor comprises a body, a first three-way valve, a second three-way valve, a pressure sensor, a first humidity sensor, a second humidity sensor and a control module. A compression cavity, a backflow channel, an exhaust cavity, a gas storage cavity, a drying cavity, a gas suction channel and an exhaust channel are formed in the body. A moisture adsorption layer is arranged in the drying cavity and located between an inlet and an outlet of the drying cavity, and a heating drying device is arranged on the moisture adsorption layer. The drying cavity and the moisture adsorption layer can dehumidify compressed gas of which the humidity exceeds the standard, so that the dryness of the gas is guaranteed; the heating drying device can evaporate moisture in the moisture adsorption layer to dry the moisture adsorption layer, so that the moisture adsorption layer is recycled. The moisture and air pressure are automatically detected, and dehumidification and compression are automatically controlled to be performed according to the detection result, so that the labor cost is low, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of gas compression, in particular to a natural gas compressor with dehumidification function. Background technique [0002] Regardless of whether it is town gas or motor vehicle gas, due to various reasons, there are always many micron-sized impurities inside the natural gas, mainly due to the incomplete desulfurization, dehydration, and dust removal of the natural gas mother station, and the corrosion of the tanks loaded with natural gas, and the existence of impurities. To 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. At present, natural gas is often filtered before compression, which cannot ensure the purity of compressed natural gas. [0003] In addition, if there is moisture in the natur...
