Description

Pressure storage heat storage seamless container
Technical Field
The invention relates to the technical field of compressed air energy storage, in particular to a pressure storage and heat storage seamless container.
Background
In order to solve the problems of huge difference of power consumption at peak and valley of the traditional power grid and wind and light abandoning of wind and solar power generation, the compressed air energy storage power generation technology is applied. The single machine capacity of the compressed air energy storage power generation system is more than 100MW, the matching degree with the traditional power grid is high, and the compressed air energy storage power generation system has the advantages of long energy storage period, small unit energy storage investment and long service life, so that the compressed air energy storage power generation technology can be rapidly developed.
In order to improve the energy storage efficiency of compressed air, the compressed air energy storage system in the prior art is provided with an air storage device for storing high-pressure air, and is additionally provided with a heat exchanger and a heat storage tank for recycling heat energy in the compressed air. The system for storing heat after all compression processes are finished compresses air to a high-temperature and high-pressure state through the compressor, the compressed air flows through the heat storage tank, partial heat energy in the compressed air is recycled by the heat storage system, and the air is cooled and stored in the air storage device. When releasing energy, the high-pressure air is released, the compressed air flows through the heat storage tank again, the stored compressed heat is utilized to heat the air, and then the expander is pushed to do work to generate power. In addition, some compressed air energy storage systems are additionally provided with heat exchangers between stages in the compression process, part of heat energy in the compressed air is recycled step by step for storage, and the temperature of the compressed air is gradually reduced to be balanced with the ambient temperature after the compressed air enters the air storage device. When releasing energy, the stored compression heat is utilized to heat the air and then the expander is pushed to do work to generate electricity.
However, no matter heat storage is performed after the whole compression process is finished or interstage heat storage is performed in the compression process, the waste heat recovery mode needs to add a heat storage tank and/or a multi-stage heat exchanger, so that not only is equipment investment increased, but also connecting pipelines between equipment are multiplied, the pressure drop of compressed air is increased, partial heat energy is recovered by sacrificing the potential energy of the compressed air and is not compensated, and the heat efficiency is also reduced by multiple heat exchange in the heat energy recovery and release processes, so that the energy conversion efficiency of the whole system is seriously influenced.
Disclosure of Invention
Based on the above problems, an object of the present invention is to provide a pressure-storing heat-storing seamless container, which can store both high-pressure compressed air and heat energy in the compressed air, thereby improving the energy conversion efficiency of the system and meeting the use requirements of the air storage device.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a store up seamless container of pressure heat-retaining, includes seamless container body, wherein, seamless container body's surface from interior to exterior has set gradually anticorrosive coating, reflection stratum, first heat preservation, second heat preservation, waterproof layer, protective layer.
In particular, the anti-corrosion layer is a urethane finish paint layer or is composed of an inner epoxy resin primer layer and an outer polyurethane finish paint layer.
Particularly, the reflecting layer is aluminum foil fiber cloth.
Particularly, the reflecting layer is coated on the outer surface of the anticorrosive layer in a forward spiral winding mode, the lap length is 50-80 mm, and steel strips are used for bundling every 200-300 mm.
Particularly, the first heat-insulating layer is nano aerogel, and the second heat-insulating layer is aluminum silicate needled blanket or glass wool.
Particularly, the first heat preservation layer is coated on the outer surface of the reflecting layer in a negative spiral winding mode, the lap length is 40 mm-60 mm, and steel strips are used for bundling every 200 mm-300 mm.
Particularly, the second heat-insulating layer is wrapped on the outer surface of the first heat-insulating layer in a mode of winding in parallel along the circumferential direction, and is wrapped in a mode of staggered joints on the same layer and laminated joints on the inner layer and the outer layer, the joints on the inner layer and the outer layer are staggered by 100-150 mm, and steel belts are used for bundling the joints at intervals of 200-300 mm.
Particularly, the second heat-insulating layer is wrapped on the outer surface of the first heat-insulating layer in a forward spiral winding mode, no lap joint is needed along the longitudinal direction, no gap is left along the longitudinal direction, and steel belts are used for bundling at intervals of 200-300 mm.
Particularly, the waterproof layer is coated on the outer surface of the second insulating layer in a negative spiral winding mode, the overlapping length is 40-60 mm, the waterproof layer is bound by a packing belt at intervals of 200-300 mm, and the binding steel belt and the packing belt of each layer are staggered longitudinally.
