Description

technical field [0001] The invention relates to thermodynamic theory and solar energy storage development and utilization technology, and specifically provides a high-temperature and high-capacity vacuum solar energy storage device. Background technique [0002] The world's energy reserves are not unlimited; they, especially the increasing shortage of energy sources such as oil and coal, have aroused great concern and anxiety among people. At the same time, the severe pollution of the atmospheric environment caused by the combustion of mineral energy fuels is also constantly deteriorating the living environment of human beings. In order to change this situation, people are always exploring the exploitation and utilization of new energy. Solar energy, as an inexhaustible, environmentally friendly and clean new energy, has received more and more attention and attention from people. Favored, all countries in the world are vigorously developing solar energ...

Problems solved by technology

However, through searching and consulting relevant information and literature, it is found that the research and development technology in this area at home and abroad is still relatively limited, and its technical application is not mature enough, mainly reflected in the fact that some are instant heating technology equipment, and the temperature is relatively high. Low heat energy storage is extremely limited; some are phase change energy storage technology equipment, although they can store more heat energy than the former, but the phase change energy storage medium generally uses solid-liquid phase change materials, resulting in more storage problems. It is the storage of solar thermal energy. Generally, a heat pump that consumes electric energy is required to transport and transfer heat energy. The second is that the energy storage medium is easily deposited in the heat transfer system pipes when the solid phase changes, hindering the effective transfer of heat. The third is The first problem is that many solid-liquid phase change energy storage media have certain toxins and corrosiveness, and the price is expensive. The fourth problem is that the energy storage is not convenient to use, and auxiliary parts need to be equipped

Relying on chemical reactions to store thermal energy is another energy storage technology researched and developed at home and abroad. The essence of this energy storage technology is that heat energy is stored in the form of binding energy of reversible chemical reactions. The shortcoming of this energy storage technology is that it participates in chemical reactions Substances have to be separated and stored separately through certain procedures, and some chemical reactions require a large amount of catalysts, which makes the saving cost higher
