Energy storage device utilizing solar energy to prepare liquefied air

Abstract

The invention discloses an energy storage device utilizing solar energy to prepare liquefied air, which comprises a solar generating set, a solar power control and output device, air compression and liquefaction equipment and a liquefied air storage tank. The power input end of the solar power control and output device is connected with the solar generating set and the power output end of the solar power control and output device is connected with the power supply end of the air compression and liquefaction equipment so as to enable power generated by the solar generating set to be intermittently output to the air compression and liquefaction equipment to drive the air compression and liquefaction equipment to work; the liquefied air output end of the air compression and liquefaction equipment is communicated with the liquefied air storage tank. According to the invention, solar energy can be stably stored and can drive running vehicles; the phenomenon of environmental pollution is avoided.

Description

technical field [0001] The invention relates to an energy storage device for producing liquefied air by using solar energy, and belongs to the new technology field of solar energy applied to transportation. Background technique [0002] At present, energy has always been scarce for human beings. With the development of renewable energy, the solar power generation industry is booming. However, to see that there is a problem of electric energy storage in the process of solar power generation and utilization, it is necessary to store the electric energy converted from solar energy. Regulates the balance of supply and demand between grid peaks and low tides. The development of the automobile industry has brought quickness and convenience to people's production and life, and at the same time brought huge environmental problems: [0003] At present, most solar-powered vehicles are small vehicles with photovoltaic roofing. In order to obtain enough energy, the top of the vehicle i...

AI Technical Summary

Problems solved by technology

[0003] At present, most solar-powered vehicles are small vehicles with photovoltaic roofing. In order to obtain enough energy, the top of the vehicle is relatively large, because the solar energy density is low, and it is not easy to store. As a result, solar photovoltaic vehicles generally have a small load and a small mileage.

And if there is a sudden change in the weather during driving, it will cause poor driving

[0004] In addition, whether solar energy is photovoltaic power generation or solar thermal power generation, there is a problem of storage and utilization of electric energy. Solar thermal power generation may be relatively good. Storage of photovoltaic power generation is a technical problem that is difficult to solve. Even if it is connected to the grid, if the amount of grid connected Especially large, because photovoltaic power generation is greatly affected by the climate, so the electricity connected to the grid is also controlled
