The air-energy-storage efficient energy recycling mechanism comprises a power supply, an air compressor, n high-pressure tanks, n-1 jet pumps, n air wheel power generators, an air purification device, a booster pump and a residual pressure tank. The power supply is connected with the air compressor. The air compressor is connected with the input ends of the n high-pressure tanks. The first air wheel power generator is installed on a high-pressure output air way of the first high-pressure tank. The first air wheel power generator is connected with the air purification device. The high-pressure output ends of the rest n-1 high-pressure tanks are connected with the first input ends of the n-1 jet pumps in a one-to-one correspondence manner correspondingly. The air wheel power generators are installed on high-pressure output air ways of the n-1 jet pumps correspondingly. Downstream air ways of the n-1 air wheel power generators are converged to the input end of the booster pump. The output end of the pressurization pump is connected with the input end of the residual pressure tank. The output end of the residual pressure tank is connected with the second input ends of the n-1 jet pumps. The air-energy-storage efficient energy recycling mechanism can purify the air environment, and the electric energy recycling rate can be increased.

Description

technical field [0001] The invention belongs to the technical field of energy storage, and in particular relates to an air energy storage and high-efficiency energy recovery mechanism. Background technique [0002] The unbalanced power load in the world is becoming increasingly prominent, and the peak-to-valley difference of the power grid is gradually widening. At the same time, people have higher and higher requirements for the power supply quality of the power grid. It is matched to alleviate the situation that the peak-to-valley difference of the system load is too large. Electric energy storage system is also an effective means to improve the utilization rate of renewable energy such as wind power and solar power. In addition, the power energy storage system is also a key technology to solve the problems of small capacity and large load fluctuation of distributed energy systems.

AI Technical Summary

Problems solved by technology

[0003] Existing solar generators include excess electric energy, air compressors, gas storage tanks and gas turbine generators. The air compressed by the air compressors is stored in the gas storage tanks. To generate electricity, high-pressure air is released from the gas storage tanks The gas generates electricity for the gas turbine generator. Since the air stored in the gas storage tank can only benefit the energy of its high-pressure gas part, the energy of its lower-pressure part is wasted, so there is little conversion of gas into electric energy, and the conversion rate is low. At the same time, the gas turbine generator can only use the energy of its high-pressure gas part, and the energy of its lower-pressure part is also wasted, resulting in a low recycling rate of excess electric energy and a large amount of waste of electric energy. The use of air compressors requires that the air should have low relative humidity, less dust, clean air and good ventilation, away from flammable, explosive, corrosive chemicals and harmful and unsafe items, and avoid places that emit dust. Under certain conditions, it will also affect the normal use of the air compressor
