Description

Technical Field

[0001] The utility model belongs to the field of air storage, and particularly relates to a high-pressure tank for compressed air energy storage. Background Art

[0002] Compressed air energy storage refers to a storage method that uses electrical energy to compress air during the low load period of the power grid, seals the air at high pressure in abandoned mines, sunken seabed gas tanks, caves, expired oil and gas wells or newly built gas storage wells, and releases the compressed air to drive the steam turbine to generate electricity during the peak load period of the power grid.

[0003] Existing compressed air energy storage requires a series of steps such as inflation and deflation operations, which requires a high intensity of use for the high-pressure tank. In addition, the existing air compression high-pressure pipe is prone to deformation during use due to the lack of an internal reinforcement structure, and the tank surface is prone to convex deformation. At the same time, when the air compressor produces compressed air, pollutants such as water, dust, and oil contained in the air itself and the lubricating oil sprayed into the air compressor during compression will be brought into the compressed air pipeline, and the pollutants formed contain some corrosive substances. In addition, the internal structure of the existing high-pressure tank is single and fixed. When the compressed air is stored for a long time, it is easy to cause corrosion to the inner wall of the tank, thereby affecting the use of the high-pressure tank and reducing the use effect of the high-pressure tank.

A protective interlayer is installed on the anti-rust inner layer to protect the internal anti-rust layer, and then an inner liner is installed inside the tank body. An anti-rust layer is set inside the inner liner to protect the inside of the tank body, so as to prevent pollutants from directly contacting the inside of the tank body and corroding the tank body, thereby improving the use of the tank body and improving the use effect of the tank body.
