Problems solved by technology

[0007] Heat pipes have been used in heat accumulators, but the service life of existing heat pipe technology is only 3-7 years, and it is difficult to guarantee a 30-year life in the field of solar energy and heat storage heating, so it is impossible to apply existing heat pipe technology to heat accumulators
[0008] However, since solar power plants and large-scale heating fields require large-scale heat storage and heat exchangers, it is impossible to achieve ground temperature difference, large-scale heat storage and heat exchange except for metal pipes. Therefore, an improved heat pipe technology is required

Abstract

The invention aims to provide a three-cavity fluid focus solar photothermal heating heat transfer heat accumulating system suitable for focus solar heat utilization, which can realize the heat accumulation with high temperature, large scale, low cost and high efficiency, and is suitable for the heat accumulation at a temperature of 10-1500 DEG C. After the heat exchange is performed between heat energy acquired by a solar focus acquisition system and a heat accumulator through a fluid, the heat energy is transferred to the heat accumulator. The heat accumulator is at least provided with three cavities: a heat charging cavity, a heat release cavity and a heat accumulating cavity; the heat charging cavity is directly exchanged heat with the solar acquisition system; the heat accumulating cavity stores the heat energy; and the heat release cavity realizes the exchange and the utilization of the heat energy. When the heat energy in the heat accumulator is required to be used, a fluid lower than a heat accumulating material in temperature flows into the heat accumulator from an inlet of the heat release cavity, and flows out from an outlet of the heat release cavity after the heat exchange with the heat accumulating material so as to realize the utilization of the heat energy.

Background technique [0002] The heat accumulator is a device for storing thermal energy, and the existing heat accumulators are steam type and liquid heat accumulators; [0003] In the field of industrial energy conservation, waste heat is recovered and stored, usually using phase change technology for heat storage, and in the low temperature field using ice storage technology for heat storage; [0004] 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 limit...
