Abstract

The invention discloses an underground constant-pressure gas storage device. The underground constant-pressure gas storage device comprises a pressure well, a gas storage chamber, a compressed gas pipeline, a balance hole, a hydraulic pipeline, a pressurizing branch and a pressure relief branch, wherein the gas storage chamber is fixed to the lower portion of the pressure well, the compressed gas pipeline is installed on the top of the gas storage chamber and connected with an external gas source or a gas load, the balance hole is located in the bottom of the gas storage chamber, the hydraulic pipeline is communicated the lower portion of the pressure well with a high-level liquid source, and the pressurizing branch and the pressure relief branch are arranged on the hydraulic pipeline. The underground constant-pressure gas storage device can keep constant internal pressure so as to meet the requirement of stable working conditions; and meanwhile, the gas storage device is located underground, so that the occupied area of the high-capacity gas storage device can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of compressed gas storage, in particular to an underground constant pressure gas storage device. Background technique [0002] The storage of compressed gas is of great significance for industrial production and daily life, such as natural gas for thermal power plants, medical oxygen, compressed air energy storage, etc. In most cases, users of compressed gas have certain requirements for the quality of the gas supply, especially for the stability of the gas supply pressure. Therefore, the outlet pressure of the gas supply device needs to be at least not lower than the pressure required by the user. When the gas in the gas supply device is discharged to a pressure lower than the pressure required by the user, the external gas supply has to be stopped, and the remaining low-pressure gas remains in the supply. On the other hand, in some cases, such as compressed air energy storage systems, since a large amount...
