Solid granular block disc type solar fluidized driving heat exchange/transfer system

Abstract

The invention provides a solid granular block disc type solar fluidized driving heat exchange / transfer system. The solid granular block disc type solar fluidized driving heat exchange / transfer system comprises a solid granular block fluidized driving pump and a solar disc type acquisition system; a solid granular block is driven by the solid granular block fluidized driving pump to go into a solar photothermal converter arranged in a focal point portion of the disc type acquisition system along a solid granular block ascending pipeline; the solid granular block is heated by using heat converted by the solar photothermal converter, such that a temperature of the solid granular block is within a range of 600-1200 DEG C; subsequently, the solid granular block goes into an accumulating heat exchanger along a descending pipeline; the accumulating heat exchanger exchanges heat with a power generating working medium, so that the temperature of the solid granular block is reduced to a range of 100-400 DEG C; the low-temperature solid granular block goes into a loading box along a connecting pipeline and then is driven by the solid granular block fluidized driving pump to go into the solar photothermal converter, and therefore, circulation of the solid granular block within a closed circulating pipeline is realized under the driving of the solid granular block fluidized driving pump, and high temperature collection, heat transfer, heat exchange and heat accumulation are realized.

Problems solved by technology

[0002] For the transmission of solid particles, the existing technology is transportation such as vehicles and ships, as well as equipment using conveyor belts and hoppers, but there is no pump for transmission like liquid transmission;

[0003] For heat transfer, water is basically used below 100 degrees, heat transfer oil is used at 100-400 degrees, and molten salt is used at 400-600 degrees, but above 600 degrees, there is currently no economical and reliable way to achieve heat transfer and heat exchange

[0004] In the field of solar energy, molten salt is used for heat storage and heat transfer. Although molten salt can achieve high-temperature storage, it needs thermal energy to heat it because it needs to change from solid to liquid. At the same time, the toxicity, economy, and safety of molten salt are also high. There are problems that limit the use of molten salt heat storage

[0005] 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

[0006] For dish solar concentrating systems, molten salt is usually used for heat transfer, but due to the limitation of molten salt temperature, it can only provide a temperature of 600 degrees. In order to achieve high temperature, air is used for heat transfer. However, the heat capacity of air is very small, so it is difficult transfer large amounts of heat
