Preferably, the temperature residing for the 3rd described storage heater S3 is 461 DEG C or so.
The compressed air and liquefied air preparation process and power generation process are staggered the time operation.The work of whole system of the present invention
Principle is as follows：During storing up electricity, air compressor 1 works, and is related to two stages of compression in the present invention, according to real process, can
Multi-stage compression can be needed.Air compressor carries cascade EDFA system, meanwhile, the waste heat of compressed air is passed through heat kerosene by heat
The 4th storage heater S4 is stored in, is that cooling of lower cycle compressed air saves energy.In the 3rd storage heater S3, waste heat supply temperature is not
With, classification storage, it is easy to the cascade utilization of waste heat.Air leaves about 150 DEG C or so of temperature after air compressor, air pressure
About 18MPa.Compressed air is cooled after First Heat Exchanger HX1 and the second heat exchanger HX2, and cooling medium one used is
From the low temperature cold air of gas-liquid separator, another part is to be stored in first from the upper cycle during liquid air release
Cold energy in storage heater S1 and the second storage heater S2.To, after First Heat Exchanger HX1 and the second heat exchanger HX2 cooling, compressing
Air themperature reaches 90K or so, and pressure keeps constant.Then, through decompressor 3, in decompressor 3, the compression of cryogenic high pressure is empty
Gas is changed into the gas-liquid mixture of low-temperature atmosphere-pressure, and in the process by joule thomson effect, process shows as absorbing heat.Gas-liquid
Mixture enters gas-liquid separator 4.In gas-liquid separator 4, gas returns through the second heat exchanger HX1 and the second heat exchanger
HX2 is mixed into the 11st heat exchanger HX11 with surrounding air after being changed into 288K, is stored by the 11st heat exchanger HX11 and the 3rd
Hot device S3 heat exchange, the regenerator temperature of the 3rd storage heater S3 is 100～190 DEG C, and its heat is used for adding between level from through the upper cycle
The waste heat of the heat kerosene of heat.Through the 11st heat exchanger HX11, before suction compressed air, its temperature is increased to 450K to air.
The liquid air that isolates from gas-liquid separator 4 enters liquid air storage tank 5 and is deposited, and now pressure is normal pressure, and temperature is
80K or so.The storage safety of liquid air, takes up an area few.Insulation is mainly carried out, prevents the entrance of external heat.
In the power generation process that releases energy, heated by cryogenic pump in the liquid air of liquefied air storage tank 5 first, air
Enthalpy is increased to 2R state by 1R.Then the cold fire of liquid air is used through the 3rd heat exchanger HX3 and the 4th heat exchanger HX4
Reclaim, be stored in the first storage heater S1 and the second storage heater S2, through changing for the 3rd heat exchanger HX3 and the 4th heat exchanger HX4
After heat, the liquid air gasification, heats up, is changed into the air of normal temperature, high pressure.Pressure is about 6.5MPa, and temperature is about 280K.?
Enter using before heat of compression preheating, first this part normal temperature high voltage air is preheated with from turbine installation air out, that is, pass through
7th heat exchanger HX7 heat exchange, reclaims to turbine installation air waste heat out, and now air can be heated to a 436K left side
The right side, to improve the efficiency of heating surface of the system.
The heat of compression produced in the hollow air pressure compression process of the system is stored in heat-storing material, for three-level in power generation process
Heat between the level of turbine 2.In power generation process, can be empty by liquid high pressure by the first storage heater S1 and the second storage heater S2
Gas is warming up to normal temperature high voltage.Before entering three-level turbine 2 and generating electricity, it is also performed to heat twice.Be for the first time from energy storage
Normal temperature high voltage atmosphere temperature rising to be generated electricity can be arrived by the heat of compression, i.e. the 4th storage heater S4 deposited in journey, this partial heat
600K or so.It is the 5th storage heater S5 for the second time, compressed air can be heated to 1273K, then the air of HTHP enters
Enter gas turbine power generation, generating efficiency is greatly improved.Efficiency for charge-discharge reaches as high as 80%.
For improving the temperature of air, the present invention utilizes S5 for storing on the basis of preheated air is carried out using the heat of compression
Deposit and substantial amounts of come from heat.This part heat is converted by the electricity of abandoning when paddy electricity or renewable energy power generation.By heat-storing material
1000 DEG C are heated to and to reach hot saturation.In power generating stage, the compressed air for heating can be added further between process level
Heat.By improving the enthalpy of compressed air come improve generating efficiency.
In compressed air, in the form of implements spatial scalable compression, at different levels keep compression ratio consistent, it is ensured that compression efficiency is most
High.During expansion power generation in turbine, the mode of staged expansion is also adopted by, at different levels expansion ratios are identical, it is ensured that generating efficiency
Highest.As the process that gas expansion generates electricity is an endothermic process, therefore, reheat in stage in the present invention, is taken.And reheating
Reheating twice is also classified into, using the heat of compression for storing, another part is utilized by paddy electricity or abandons the storage that electricity is transformed a part
Exist in heat-storing material.
In storage heater S5, taken is the mode of accumulation of heat.It is exactly that heat-storing material is heated by electricity consumption first, by electricity with heat
Form is deposited.Then, pressure-air absorbs heat by way of heat exchange, improves air enthalpy.The first storage heater S1, first
In storage heater S2, the first storage heater S3 and the first storage heater S4, heat energy is transmitted by heat kerosene or coolant media, final storage
In energy-accumulation material.
Above-listed detailed description is illustrating for possible embodiments of the present invention, and the embodiment is simultaneously not used to limit this
Bright the scope of the claims, all equivalence enforcements without departing from carried out by the present invention or change, are intended to be limited solely by the scope of the claims of this case.
