Abstract

The invention relates to the technical field of gas storage equipment, in particular to a gas storage device and method. The Gas storage device comprises a rigid gas storage cavity immersed in an environmental liquid, wherein gas is stored in a underwater gas storage way, so that a ground space can be saved; an inner liquid level is formed in the gas storage cavity to liquid-seal gas in the gas storage cavity and the gas is located above the inner liquid level, an inner liquid below the inner liquid surface communicates with the environmental liquid, and the inner liquid surface ascends and descends along with change of an air pressure when the gas storage cavity is inflated or deflated. Matched with the rigid gas storage cavity, gas is stored, and the liquid can enter into or can be discharged out of the gas storage cavity automatically as compressed gas in the gas storage cavity is inflated and deflated, and the air pressure in the gas storage cavity is stabilized by means of hydraulic pressure. As the inner and outer pressures of the gas storage cavity are consistent, the requirement on intensity of a gas storage cavity body is reduced, so that the material cost can be lowered effectively. In addition, the gas storage cavity does not deform along with inflation and deflation, so that the service life is longer. The device is simple in structure and easy to process and manufacture and simple in later operation and maintenance.

Description

technical field [0001] The invention relates to the technical field of gas storage equipment, in particular to a gas storage device and method. Background technique [0002] Gas storage is widely used in many fields such as life and production, such as storage of natural gas, storage of medical oxygen, storage of compressed air in compressed air energy storage power stations, etc. [0003] There are two types of conventional gas storage: gaseous storage and liquefied storage. Gaseous gas storage technology is less difficult and easy to apply directly, but because of the low density of the gas, there are disadvantages of large gas storage area and high gas storage pressure; at the same time, with the process of charging and discharging, the gas storage device The pressure inside will rise or fall, resulting in pressure fluctuations during the inflation and deflation process. Liquefied gas storage has the advantages of small footprint and high storage density, but because th...
