Problems solved by technology

[0005] In the field of solar energy, molten salt is used to store heat. Although molten salt can achieve high temperature storage, it needs heat energy to heat it because it needs to be transformed from solid to liquid. At the same time, there are problems with the toxicity, economy, and safety of molten salt. , so the use of molten salt heat storage is limited
[0006] In the field of solar energy, air or other gases are also used for heat storage, but its thermal fusion is small, and large-scale thermal energy storage cannot be realized
[0007] The energy storage power station uses electric energy for storage, especially the electric energy composed of wind power and photovoltaic, because it cannot be stored, it has to be discarded in large quantities, causing a lot of waste

The invention provides a low-temperature solar single-cavity heat accumulating wall system. The low-temperature solar single-cavity heat accumulating wall system comprises a container at least having a cavity, wherein a heat accumulating material is arranged in the container; the container is arranged above the ground, and an insulation material is arranged outside the container to form a wall structure; the low-temperature solar single-cavity heat accumulating wall system further comprises at least one set of solar low-temperature acquisition systems; solar acquisition parts are arranged outside the cavities; a first heat exchange device is arranged for finishing the heat exchange between the solar low-temperature acquisition systems and the heat accumulating material in the container; and the solar low-temperature acquisition systems exchange the acquired heat energy to the heat accumulating material of the heat accumulating cavities through the first heat exchange device so as to realize the acquisition and storage integration of the heat energy. The low-temperature solar single-cavity heat accumulating wall system can realize the application with large scale, low cost, high efficiency and seasonal heat accumulation, and belongs to a non-tracking solar system; afterheat acquired from solar energy is exchanged with a heat accumulator; firstly, the heat energy is stored in large scale; and then, the heat energy is used.

Description

technical field [0001] The invention relates to utilization of thermal energy, in particular utilization of heat storage and large-scale cross-season utilization of a solar low-temperature heat collection system. Background technique [0002] The low-temperature heat utilization of solar energy is mainly used for hot water and heating, and can also be used for cooling, but basically it is used in the season of the day, and it is mainly used in households and small-scale. The main reason is that its storage and collection capabilities are limited. , so it cannot be used on a large scale and across seasons. [0003] If it is used across seasons, it is first necessary to improve the heat accumulator, which is a device for storing heat energy. The existing heat accumulators are steam type and liquid heat accumulators; [0004] In the field of industrial energy conservation, waste heat is recovered and stored, usually using phase change technology for heat storage, and in the lo...
