Abstract

The invention discloses a novel heat accumulating type compressed air energy storage system. On the basis of a heat accumulating type compressed air energy storage system, work procedures of the system are optimized, by the characteristic that a compressor unit and an expansion unit share a heat exchanger, the compressor unit, a heat accumulating system and the expansion unit are coupled together well through a three-way reversing valve, and problems that interstage heat exchangers of the heat accumulating type compressed air energy storage system are arranged repeatedly, system processes are not reasonable, excessive lands are occupied, cost is high, heat energy utilization rate is low, then system running efficiency is reduced and the like are solved. The novel heat accumulating type compressed air energy storage system has the advantages of simple and compact structure, high system efficiency, good heat exchange effect, low manufacturing cost and the like.

Description

technical field

[0001] The invention relates to the technical field of energy storage, in particular to a novel regenerative compressed air energy storage system. Background technique

[0002] The traditional compressed air energy storage system is an energy storage system developed based on gas turbine technology. The working principle is: during low power consumption, the air is compressed and stored in the gas storage chamber, so that the internal energy converted from electric energy into air is stored; during the peak power consumption, high-pressure air is released from the gas storage chamber and enters the combustion chamber of the gas turbine together with the fuel. Combustion, and then drive the turbine to generate electricity. One of the problems of traditional compressed air energy storage systems is that they still rely on burning fossil fuels to provide heat sources. On the one hand, they are facing the threat of fossil fuels being depleted and prices rising. ...
