Island air energy storage system

Abstract

The invention discloses an island air energy storage system, and relates to the field of energy storage. The island air energy storage system comprises an air storage chamber, a heat accumulator and acompressor, wherein an air storage plate is laid in the air storage chamber, an air valve is arranged between an air outlet of the air storage chamber and a connecting pipeline of a turbine, and an air storage bin and a heat exchange flow channel are arranged in the air storage plate; and an inlet of the air storage bin is connected with an outlet of the compressor, a plurality of heat exchange plates which are arranged in a stacked mode are arranged in the heat accumulator, heat exchange flow channels are also formed in the heat exchange plates, the plurality of heat exchange plates sequentially communicate from top to bottom, and the heat exchange flow channels of the heat exchange plates communicate with the heat exchange flow channel of the air storage plate in a closed mode. According to the energy storage system, air compression energy is divided into heat stored in the heat accumulator, energy of high-pressure gas in the air storage chamber and spring potential energy in a power generation device, and the overall energy storage load capacity of the energy storage system is greatly improved. The heat of compressed air is stored and reused, so that the energy loss is reduced,and the utilization rate of electric power is increased.

Description

technical field [0001] The invention relates to the field of energy storage, in particular to an isolated island air energy storage system. Background technique [0002] With the depletion of non-renewable energy, the energy crisis has become the focus of global attention, and the use of new energy will become the biggest breakthrough to solve this problem. [0003] However, some island-like regions such as the Qinghai-Tibet Plateau are rich in new energy sources such as wind energy and solar energy, but they face the unpredictability and instantaneous intermittency of new energy sources. Therefore, suitable energy storage technology will be more conducive to the long-term development of new energy generation. Air energy storage technology is a kind of physical energy storage method. It is equivalent to pumped energy storage in terms of technical maturity, and its cost is lower than that of pumped energy storage. It has excellent performance in storage time, discharge power...
