Description

Technical Field

[0001] This utility model relates to the field of compressed air energy storage technology, and in particular to an adaptive multilayer composite compressed air energy storage chamber. Background Technology

[0002] Compressed air energy storage (CASS) is a novel energy storage method that has seen widespread application in recent years in areas such as power peak shaving and renewable energy utilization. This technology converts electrical energy into compressed air for storage during periods of low electricity demand and releases the compressed air to drive generators during periods of high demand, thus achieving the spatial and temporal transfer of energy and balancing of grid load. Compared to traditional energy storage methods such as pumped hydro storage, CASS has higher energy density and wider geographical adaptability, being unrestricted by terrain and water resources, and has therefore attracted increasing attention globally. In a CASS system, the air storage chamber is one of the core components, its main function being to store high-pressure air compressed by a compressor.

[0003] Traditional compressed air storage chambers are typically made of a single material, such as metal or concrete. However, single-material chambers have inherent drawbacks, such as material fatigue, insufficient pressure resistance, and stability issues under high pressure. These problems not only affect the service life and safety of the chamber but also hinder the further development and application of compressed air energy storage technology. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a compressed air energy storage adaptive multilayer composite gas storage chamber, which can significantly improve the strength, pressure resistance, and safety of the gas storage chamber.

[0005] The compressed air energy storage adaptive multilayer composite gas storage chamber according to an embodiment of the present invention includes:

[0006] Outer metal casing;

[0007] A middle composite material layer is attached to the inner surface of the outer metal shell;

[0008] An inner elastic material layer is attached to the inner surface of the middle composite material layer.

[0009] The compressed air energy storage adaptive multilayer composite gas storage chamber according to the present invention has the following advantages: by attaching the middle composite material layer to the inner surface of the outer metal shell and attaching the inner elastic material layer to the inner surface of the middle composite material layer, a highly integrated multilayer composite structure is formed, ensuring the tight bonding and synergistic operation of each layer of material. In this multi-layer composite structure, the outer metal shell is made of high-strength metal material, capable of withstanding physical stress under high pressure. This outer shell possesses excellent impact resistance, effectively resisting external environmental factors such as temperature changes, corrosion, and mechanical wear, ensuring the long-term stable operation of the gas storage chamber under harsh conditions. The outer shell plays a major supporting role in the overall structure, ensuring the overall safety of the gas storage chamber. The middle composite material layer is composed of various high-performance composite materials, possessing high strength, low density, and excellent fatigue resistance, enhancing the overall structural strength and stability of the gas storage chamber. The inner elastic material layer is made of highly elastic and wear-resistant material, enabling rapid response to pressure changes, adaptive deformation, and automatic adjustment of shape and stress distribution. This mitigates the impact of internal pressure fluctuations on the compressed air energy storage adaptive multi-layer composite gas storage chamber of this embodiment, providing additional buffering and sealing effects. The inner elastic material layer also effectively absorbs and mitigates vibrations and noise generated during gas storage, further improving the operational stability and safety of the gas storage chamber. Therefore, the adaptive multilayer composite compressed air storage chamber of this utility model combines the advantages of each layer of materials, optimizes the structural performance, extends the service life of the storage chamber, and ensures safety and reliability during long-term high-pressure energy storage.

[0010] In summary, the adaptive multilayer composite compressed air storage chamber of this utility model significantly improves the strength, pressure resistance, and safety of the storage chamber through the combination of multiple materials and the design of intelligent structures, thus solving the inherent defects of traditional single-material storage chambers.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] The following is combined Figure 1 This invention describes an embodiment of a compressed air energy storage adaptive multilayer composite air storage chamber.

[0026] like Figure 1 As shown, the compressed air energy storage adaptive multilayer composite gas storage chamber according to an embodiment of the present invention includes an outer metal shell 1, a middle composite material layer 2, and an inner elastic material layer 3 stacked sequentially from the outside to the inside.

[0027] Specifically, the middle composite material layer 2 is adhered to the inner surface of the outer metal shell 1, and the inner elastic material layer 3 is adhered to the inner surface of the middle composite material layer 2, thereby forming a highly integrated composite structure. In actual use, when compressed air is injected into the compressed air energy storage adaptive multilayer composite gas storage chamber of this embodiment, the inner elastic material layer 3 first adaptively deforms to absorb part of the air pressure impact; the middle composite material layer 2 provides the main pressure resistance support; and the outer metal shell 1 provides overall structural protection, ensuring the safety and stability of the gas storage chamber.

[0028] The compressed air energy storage adaptive multilayer composite gas storage chamber according to the present utility model has the following advantages: by attaching the middle composite material layer 2 to the inner surface of the outer metal shell 1 and attaching the inner elastic material layer 3 to the inner surface of the middle composite material layer 2, a highly integrated multilayer composite structure is formed, ensuring the tight bonding and synergistic operation of each layer of material. In this multi-layer composite structure, the outer metal shell 1 is made of high-strength metal material, capable of withstanding physical stress under high pressure. This outer shell possesses excellent impact resistance, effectively resisting external environmental factors such as temperature changes, corrosion, and mechanical wear, ensuring the long-term stable operation of the gas storage chamber under harsh conditions. The outer shell plays a major supporting role in the overall structure, ensuring the overall safety of the gas storage chamber. The middle composite material layer 2 is composed of various high-performance composite materials, possessing high strength, low density, and excellent fatigue resistance, enhancing the overall structural strength and stability of the gas storage chamber. The inner elastic material layer 3 is made of highly elastic and wear-resistant material, enabling rapid response to pressure changes, adaptive deformation, and automatic adjustment of shape and stress distribution. This mitigates the impact of internal pressure fluctuations on the compressed air energy storage adaptive multi-layer composite gas storage chamber of this embodiment, providing additional buffering and sealing effects. The inner elastic material layer 3 also effectively absorbs and mitigates vibrations and noise generated during gas storage, further improving the operational stability and safety of the gas storage chamber. Therefore, the adaptive multilayer composite compressed air storage chamber of this utility model combines the advantages of each layer of materials, optimizes the structural performance, extends the service life of the storage chamber, and ensures safety and reliability during long-term high-pressure energy storage.

[0029] In summary, the adaptive multilayer composite compressed air storage chamber of this utility model significantly improves the strength, pressure resistance, and safety of the storage chamber through the combination of multiple materials and the design of intelligent structures, thus solving the inherent defects of traditional single-material storage chambers.

[0030] In some embodiments, the outer metal shell 1 and the middle composite material layer 2, as well as the middle composite material layer and the inner elastic material layer 3, are bonded together. This bonding can be achieved using an adhesive process or a hot-pressing process. The adhesive process uses a high-strength adhesive to tightly bond the layers together, ensuring a strong bond and stress transfer between the layers. The hot-pressing process, by pressing the layers together under high temperature and pressure, achieves a tight bond at the molecular level, further enhancing the strength and stability of the overall structure.

[0031] In some embodiments, the outer metal casing 1 is a titanium alloy casing or a stainless steel casing. Titanium alloy and stainless steel casings possess good mechanical strength and corrosion resistance, providing overall structural support.

[0032] In some embodiments, the middle composite material layer 2 is composed of N composite material sublayers stacked together, where N is a natural number greater than or equal to 1. That is, the middle composite material layer 2 can consist of a single composite material sublayer or multiple composite material sublayers stacked together. The middle composite material layer 2 obtained by stacking multiple composite material sublayers can achieve a more uniform stress distribution, reduce local stress concentration, and further improve the overall structural strength and stability of the gas storage chamber. The number of composite material sublayers in the middle composite material layer 2 can be selected according to actual needs.

[0033] In some embodiments, the composite sublayer is a layer composed of carbon fiber, glass fiber, and resin materials. This composite sublayer has high strength, low density, and excellent fatigue resistance, which can improve the overall structural strength and stability of the gas storage chamber.

[0034] In some embodiments, the thickness of the middle composite material layer 2 may be the same or different at different locations, and can be adjusted according to actual needs. The different thicknesses at different locations of the middle composite material layer 2 can be achieved through a multi-layer composite material sub-layer stacking process. For example, the thicker locations of the middle composite material layer 2 have a relatively larger number of composite material sub-layers, while the thinner locations have a relatively smaller number of composite material sub-layers. This stacked design of the middle composite material layer 2 achieves a more uniform stress distribution, reduces local stress concentration, and further improves the overall structural strength, pressure resistance, and stability of the gas storage chamber.

[0035] In some embodiments, the inner elastic material layer 3 is a highly elastic rubber layer or a polymer material layer. The highly elastic rubber layer and polymer material layer can respond rapidly to changes in air pressure, undergo adaptive deformation, and automatically adjust their shape and stress distribution, thereby mitigating the impact of internal pressure fluctuations on the adaptive multilayer composite compressed air storage chamber of this embodiment, providing additional buffering and sealing effects. The inner elastic material layer 3 can also effectively absorb and mitigate vibrations and noise generated during the gas storage process, further improving the operational stability and safety of the gas storage chamber.

[0036] In some embodiments, the highly elastic rubber layer is a silicone rubber layer. The silicone rubber layer can respond rapidly to changes in air pressure, undergo adaptive deformation, and automatically adjust its shape and stress distribution, thereby mitigating the impact of internal pressure fluctuations on the adaptive multilayer composite air storage chamber of the compressed air energy storage embodiment of this utility model, and providing additional buffering and sealing effects; the silicone rubber layer can also effectively absorb and mitigate vibrations and noise generated during the air storage process, further improving the operational stability and safety of the air storage chamber.

[0037] In some embodiments, the polymer material layer is a polyurethane layer. The polyurethane layer can respond rapidly to changes in air pressure, undergo adaptive deformation, and automatically adjust its shape and stress distribution, thereby mitigating the impact of internal pressure fluctuations on the adaptive multilayer composite gas storage chamber of the compressed air energy storage embodiment of this utility model, and providing additional buffering and sealing effects; the polyurethane layer can also effectively absorb and mitigate vibrations and noise generated during the gas storage process, further improving the operational stability and safety of the gas storage chamber.
