Problems solved by technology
However, the thermochemical energy storage reaction system needs to meet many conditions, such as good reaction reversibility, rapid reaction and small side reactions, stable storage of products, and low price. Matching and other problems limit the application of solar thermal chemical energy storage
At present, high-temperature solar thermochemical energy has problems such as low utilization rate, high requirements for reaction devices, and expensive concentrating systems.

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings.
[0018] Such as figure 1 As shown, the solar heat storage and release system of this embodiment includes a solar medium-high temperature air heat collector 1, one side of the solar medium-high temperature air heat collector 1 is provided with an air inlet 19, and the other side is connected to the material to absorb heat through the air outlet 20 Decomposition equipment 3, a high-temperature intelligent centrifugal fan 2 is provided on the air outlet 20, and the high-temperature intelligent centrifugal fan 2 adjusts the air volume to discharge gas through frequency conversion and speed regulation. The air inlet 19 is sucked in, and after the air passes through the medium-high temperature solar air heat collector 1 to collect heat, the hot air flows from the air outlet 20 through the high-temperature intelligent centrifugal fan 2, and flows to the high-temperature air in...

Description
technical field [0001] The invention belongs to the technical field of solar energy storage and storage, and relates to medium and high temperature solar heat storage and storage, in particular to a solar energy storage and release system. Background technique [0002] As a new energy source, solar energy is affected by regular changes in geography, day and night, and seasons, as well as random factors such as cloudy, cloudy, and rainy, and has defects such as low energy density, intermittent, periodic, and large fluctuations, which are difficult to meet Industrialized large-scale continuous and stable energy supply requirements. In order to make solar energy a continuous and stable energy source, it is necessary to solve the problem of energy storage, that is, to store solar energy in sunny days for use at night or in rainy days. [0003] At present, there are three main methods of solar medium and high temperature energy storage: sensible heat, phase change energy storage...
