Description
Technical Field

Background
Compressed Natural Gas (CNG) refers to a gaseous Natural Gas Compressed to a pressure of 10MPa or more and not more than 25MPa, and is a Natural Gas that is pressurized and stored in a gaseous state in a container. The CNG gas station comprises a mother station, a standard station and a sub-station. The gas filling main station generally takes gas from a high-pressure pipeline to fill gas into the CNG gas cylinder vehicle, and then the CNG gas cylinder vehicle is conveyed to the sub-station to supply gas, and meanwhile, the gas filling main station has the capability of directly filling gas into the CNG vehicle.
Usually, the gas pressure of the gas source of the mother station is about 5MPa, and in the process of conveying natural gas by adopting the CNG gas cylinder vehicle, the natural gas with the pressure of about 5MPa needs to be further boosted to meet the loading pressure requirement of the CNG gas cylinder vehicle.
In the prior art, in order to realize the pressurization of the compressed natural gas, a compressor and a storage tank are usually required to be arranged in a mother station, the compressor compresses the natural gas step by step to improve the pressure of the natural gas, then the pressurized natural gas is stored in the storage tank, and the storage tank is directly connected with a gas filling column. When shifting the natural gas to the CNG gas cylinder car, the natural gas after the compression in the holding vessel is at first shifted to the CNG gas cylinder car in, when the natural gas pressure in the holding vessel reduces and can not satisfy the air entrainment demand, start the pressurization that the compressor will carry out the natural gas again. Although the method can realize the pressurization process of the natural gas, after the pressure of the natural gas in the storage tank is reduced, the natural gas needs to wait for the pressurization of the natural gas to meet the loading requirement, so the method has the defects of low pressurization speed, incapability of quickly filling the natural gas into a CNG gas cylinder vehicle and the like. Meanwhile, when the parent station is disposed at some place where the ambient temperature is low, the natural air temperature in the pipeline is often too low due to various reasons. The natural gas with too low temperature has high density, the compressor needs to output more power for compression after entering the compressor, and when the airflow is increased, the cold natural gas can transfer the load to the piston rod of the compressor, thereby causing the problem of the piston rod. In addition, the compressed natural gas with lower temperature is not easy to take out from the storage tank, part of the low-temperature natural gas is often left in the storage tank, the low-temperature natural gas is discharged from the storage tank at a relatively lower speed than the natural gas at normal temperature, and the loading speed of the CNG gas cylinder truck is further influenced.
