Description

Technical Field

[0001] The present invention relates to the technical field of compressed air energy storage, and particularly to a gas storage tank support device, its construction method, and a compressed air energy storage system. Background Art

[0002] In the field of large-scale physical energy storage technologies, advanced compressed air energy storage technology, as a new form of energy storage, has been widely promoted and demonstrated. Since high-pressure air is used for energy storage, its energy storage density is much lower than that of a liquid compressed air energy storage system. Although it gets rid of the geographical location constraints of the traditional compressed air energy storage system and enables more flexible promotion and application, there are still problems such as large floor area and high investment cost. Moreover, the gas storage device of the compressed air gas storage system also has the problem of difficult maintenance.

[0003] In order to reduce the large floor area problem of the compressed air energy storage system. In the prior art, the above-ground gas storage device is constructed in the form of a pressure vessel or industrial pipeline with a large length-to-diameter ratio, and in order to effectively save the floor area of the gas storage device, a multi-layer structure is adopted for arrangement. However, the gas storage device with a multi-layer arrangement structure in the prior art will bring the following problems:

[0004] 1. The multi-layer arrangement structure in the prior art poses great difficulties to the strength of the support structure of the gas storage device. Because, the lower the support structure, the multiple increase in the strength required. And it also places a very large pressure on the strength of the foundation of the entire gas storage device;

[0005] 2. The existing gas storage tanks are arranged in a multi-layer fixed manner. Therefore, when a gas storage pipeline near the lower layer fails and needs maintenance, the operation space for on-line maintenance is relatively limited, and it is very difficult to remove it for repair.

[0006] 3. The existing gas storage tanks are arranged in a multi-layer fixed manner, with high requirements for the support structure and the strength of the foundation, resulting in a large increase in the input cost of the entire gas storage device.

[0007] 4. The multi-layer arrangement structure poses great difficulties to equipment welding and installation, with a long construction period and uncontrollability.
