Embodiment 1

[0024] The compressed air energy storage liner cavity sealed by the integral rubber bag of embodiment 1, such as Figure 1 to Figure 3 As shown, it includes the compressed gas storage lining cavern 8, the integral rubber bladder 3 and the drainage ditch 21. The compressed gas storage lining cavern 8 is excavated in the surrounding rock 1 with good integrity, and the integral rubber bladder 3 is set In the compressed gas storage lined cavern 8, the drainage ditch 21 is excavated at the bottom of the compressed gas storage lined cavern 8, and the integral rubber bag 3 is used for sealing the compressed gas storage lined cavern 8, and the integral rubber bag 3 When inflated, it is closely attached to the lining wall of the compressed gas storage lining cave 8; during the inflation process, the integral rubber bag 3 is closely attached to the lining wall of the compressed gas storage lining cave 8, and the internal pressure is transmitted to the surrounding rock 1 , the reaction o...

Embodiment 2

[0029] The difference between the compressed air energy storage liner cavity sealed by the integral rubber bag of Example 2 and Example 1 is that in Example 2, as Figure 4 As shown, the inner wall of the reinforced concrete layer 2 is laid with a layer of geotextile layer 18, and the geotextile layer 18 is fixed on the inner wall of the reinforced concrete layer 2 by a number of cement nails 19, and each cement nail 19 and the geotextile layer 18 are compacted and arranged There are spacers 20.

[0030] After the construction of the above-mentioned compressed air energy storage lining cavern, during the inflation process, the air compressor 10 uses the surplus electric energy in the power grid 12 to compress the air in the atmosphere, and the compressed gas enters the integral rubber bag 3 along the intake pipe 6, and the overall The rubber bladder 3 expands under the action of gas pressure. When the integral rubber bladder 3 is fully inflated, the integral rubber bladder 3 i...

Abstract

The invention discloses a compressed air energy storage lining cavern sealed by an integral rubber capsule, which comprises a compressed air energy storage lining cavern, an integral rubber capsule and a drainage ditch; the compressed air energy storage lining cavern is excavated in surrounding rock with good integrity; the integral rubber capsule is arranged in the compressed air energy storage lining cavern; the drainage ditch is excavated at the bottom of the compressed air energy storage lining cavern; and the integral rubber capsule is used for sealing the compressed air energy storage lining cavern and is tightly attached to the lining wall face of the compressed air energy storage lining cavern when being inflated and expanded. In the inflation process, the integral rubber capsule is tightly attached to the lining wall face of the compressed air energy storage lining cavern, and the compressed air energy storage lining cavern is sealed; and in the deflation process, the integral rubber capsule is separated from the lining wall face of the compressed air energy storage lining cavern, and underground water permeating into the compressed air energy storage lining cavern is discharged out of the cavern through the drainage ditch. Compared with an existing compressed air energy storage lining cavern, the compressed air energy storage lining cavern of the invention is wider in application range, better in feasibility, smaller in leakage rate and lower in risk and cost.

Description

technical field [0001] The invention relates to the technical field of underground energy storage to achieve the dual goals of "carbon peaking and carbon neutralization", in particular to an integral rubber-bag-sealed pressurized energy storage lined chamber. Background technique [0002] The primary measure to achieve the goal of carbon peaking is to reduce the use of fossil energy and increase the use of green renewable energy such as wind power and photovoltaic power. Although green renewable energy sources such as wind power and photovoltaic power are more environmentally friendly than traditional fossil energy sources, due to their intermittent and fluctuating nature, the stability and continuity of power generation are relatively insufficient. In order to solve the above problems, it is necessary to use large-scale energy storage technology, and compressed air energy storage is a commonly used large-scale energy storage technology. Compressed air energy storage techno...
