The invention discloses a porous medium heat transfer and storage device, a heat transfer and storage power generation system and an energy storage power station. The porous medium heat transfer and storage device includes a heat accumulator and a heating unit, the heat accumulator is a tubular structure, the two ends of the heat accumulator are respectively provided with a low temperature port and a high temperature port, and the heat accumulator is internally provided with multiple ports. The circulation channels are arranged up and down, and the circulation channels are filled with a heat storage working medium; the heating unit is connected to the heat accumulator, and is used for heating the heat transfer working medium in the heat accumulator; wherein, the The heat storage medium is a porous medium. For the porous medium heat transfer and storage device, a low-cost porous medium filler with a heat capacity per unit volume greater than the heat capacity of molten salt is used as the heat storage medium, which reduces the cost of the heat storage medium and the heat accumulator, thereby reducing the cost of the energy storage power station. In addition, compared with the use of molten salt with a high melting point for heat storage, the use of anti-condensation and freezing blocking equipment is reduced, and the safety risk and cost of operation are reduced.
Description
technical field [0001] The invention relates to the technical field of energy storage, in particular to a porous medium heat transfer and storage device, a heat transfer and storage power generation system and an energy storage power station. Background technique [0002] Among the technological advancements that are transforming the energy industry, energy storage technologies are increasingly important and will fundamentally change the world's energy mix. In order to effectively deal with the energy crisis brought about by the exhaustion of fossil energy, it is necessary to seek alternatives to fossil energy, such as wind energy, solar energy and other renewable energy sources. No matter what kind of renewable energy, a large part must be converted into electricity to be used. However, while my country is vigorously developing renewable energy, the phenomenon of power abandonment is becoming more and more serious. In 2019, the national abandoned wind power was 16.9 billio...
