Background
The storage of compressed gas is of great significance for industrial production and daily life, such as natural gas, medical oxygen, compressed air energy storage and the like for thermal power plants. In most cases, the user of compressed gas has certain requirements on the quality of the supply gas, in particular the stability of the supply gas pressure. Therefore, the outlet pressure of the gas supply device at least needs to be ensured to be not lower than the pressure required by a user, when the gas in the gas supply device is discharged to the pressure lower than the pressure required by the user, the external gas supply has to be stopped, and the residual low-pressure gas remains in the gas supply device and cannot be utilized, so that the utilization rate of stored gas is low; on the other hand, in some cases, such as in a compressed air energy storage system, since a large amount of air needs to be compressed and stored in the air storage device, the air compression apparatus has to continuously adjust the operation condition as the pressure in the air storage device increases, which complicates the operation of the compression apparatus, and the operation deviating from the designed operation condition deteriorates the working life of the air compression apparatus. In addition, the large-capacity gas storage device also has the disadvantages of overlarge occupied area and the like.
