The invention relates to a heat energy storage device of a solar generating device, which comprises a heat energy storage chamber, a heat energy storage cabin and a heat energy transmitter, wherein the heat energy storage chamber is provided with an air inlet and an air outlet; the heat energy storage cabin is arranged in the heat energy storage chamber and fixed at the bottom of the heat energy storage chamber; one end of the heat energy cabin is an opening end used as an air inlet, while the other end of the heat energy cabin is a sealing end which is internally filled with heat energy storage media; the heat energy transmitter is positioned in the heat energy storage chamber and provided with three openings, one opening is inserted at an air inlet of the heat energy storage chamber and communicated with a heat energy transmission pipe, the other opening is inserted and connected to the opening end of the heat energy storage cabin, the last opening is inserted at an air outlet of the heat energy storage chamber and communicated with an air inlet of a steam generator, and the three openings are respectively provided with an air valve. The heat energy storage device improves the heat energy storage performance, minimizes the heat energy transmission loss, can realize the free circulation and exchange of air and is convenient for the input and the output of energy. The heat energy storage chamber is directly connected with the steam generator so as to reduce the energy transmission loss and improve the heat transmission efficiency.

Description

technical field [0001] The invention relates to a solar power generation device, in particular to a thermal energy storage device of the solar power generation device. Background technique [0002] Energy is the cornerstone of the existence and development of modern society. With the continuous development of the global economy and society, energy consumption also continues to grow accordingly. At present, fossil energy (petroleum, coal, natural gas, etc.) is the main component of global energy consumption, and its total consumption is increasing year by year. However, fossil energy is non-renewable and has limited storage, so the shrinkage of production is inevitable. In addition, problems such as environmental pollution and greenhouse effect caused by the use of fossil energy are also important factors that plague economic and social development. Against the background of increasingly tense supply of fossil energy, all countries in the world are striving to find a stabl...

Problems solved by technology

[0004]The disadvantages of the thermal energy storage in the existing solar power generation device mainly include: the thermal energy storage medium of the thermal energy storage generally adopts salt or oil; Conduction requires the use of external force to push the movement of the salt medium to achieve energy transmission; the oil medium has high requirements on the sealing performance of the transmission pipeline, so the cost is high, and the oil medium is easy to burn and explode, especially in the field of solar power generation, light, heat, electricity, etc. External conditions are more likely to cause combustion and explosion, and the safety performance of use is not good

Its transmission pipeline has no valve control structure, which makes the storage and discharge of energy difficult to control

The hot air transmission pipeline between the heat energy collection device, the storage device and the power generation device is long, resulting in a large energy loss
