Abstract

The invention relates to a carbon dioxide energy storage and supply system, which comprises an organic working medium power generation unit, a carbon dioxide energy storage unit, a heat exchanger, a carbon dioxide fan, a carbon dioxide expander, a first generator, a calcium carbonate preparation unit and a calcium oxide water absorption unit. The carbon dioxide energy storage unit is connected to the organic working medium power generation unit by means of a liquid/solid carbon dioxide pipe; the organic working medium power generation unit is connected to the carbon dioxide fan; an outlet of the carbon dioxide fan is connected to the head exchanger by means of a high-pressure carbon dioxide pipe; an outlet of the heat exchanger is connected to the carbon dioxide expander; an outlet of the carbon dioxide expander is connected to an exhaust emission unit, a carbon dioxide compression and recycling unit, and the calcium carbonate preparation unit. The carbon dioxide energy storage and supply system enables low-temperature utilization with carbon dioxide stored energy, thus effectively storing and utilizing surplus energy and achieving flexible regulation and utilization of energy.

Description

technical field [0001] The invention belongs to the technical field of energy storage and energy utilization, and relates to a carbon dioxide energy storage and energy supply system. Background technique [0002] Energy storage technology can realize the effective storage of energy and complete the efficient release of energy when needed. Using energy storage technology, the energy supply system can convert surplus energy into cold energy at any time, and use carbon dioxide for low-temperature storage, thereby effectively reducing energy waste. How to use carbon dioxide as a carrier to realize the energy storage and energy supply of the energy supply system, improve the utilization rate of energy, and reduce the waste of energy is an important challenge for the energy supply system. [0003] Energy storage and supply systems using carbon dioxide as the working medium are relatively rare. Carbon dioxide is a non-toxic, non-flammable, high-density, suitable critical point (c...
