Energy storage power generation system using new energy resource liquefied air

Abstract

The invention relates to an energy storage power generation system using new energy resource liquefied air. The system comprises a clean air reusing system, a wind energy driving system, a liquefied air system, a liquid-state air power generation system and a solar heating system, air discharged from low and intermediate temperature heat exchangers is led into an inlet air constant pressure tank to be joined into fresh air, and the air is reused after the pressure is stable; the wind energy driving system uses wind energy to directly drive an air compressor to work, and then compressed air isenabled to pass through a pressure stabilization tank to stabilize the pressure of the compressed air; according to the liquefied air system, the air stable in pressure passes through a vortex tube firstly, air coming out from the vortex tube is divided into hot air flow and cold air flow, the hot air flow enters the intermediate temperature heat exchanger to preheat the liquefied air, the cold air flow enters a refrigerating machine to be liquefied, and finally, the liquefied air enters a storage tank to be stored; according to the liquid-state air power generation system, air led out from aliquid-state storage tank is heated by a heat exchanger and then passes through a full-flow screw expander to do work, and a power generator is driven to generate power; and the solar heating system heats liquefied air through a high temperature heat exchanger. According to the energy storage power generation system using new energy resource liquefied air, new energy resources are used, and the new energy resource using rate is effectively improved.

Description

technical field [0001] The invention relates to an energy storage and power generation system utilizing new energy liquefied air, in particular to a novel integrated energy storage and power generation system and process utilizing clean energy, belonging to the technical field of green energy. Background technique [0002] Energy is an important support for the modern economy, an important foundation for the survival and development of human society, and plays an indispensable and important role in promoting social development. Since the beginning of industrialization, coal, oil, natural gas and other fossil fuels have become the material basis for the survival of human society. With the rapid development of China's economy and rapid population growth, the demand for energy is increasing. The increase in energy consumption and the dwindling of traditional energy resources can no longer meet the needs of national economic development. In addition, the deterioration of the ec...
