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, 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 exchange except for air. hot
[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 limited
[0005] In the field of solar energy, air or other gases are also used for heat transfer and heat storage for heat energy above 600 degrees, but its thermal fusion is small, and large-scale heat energy storage cannot be realized

Abstract

The invention provides a solid particle high-temperature heat transfer and pulse driving heat transfer system. According to the solid particle high-temperature heat transfer and pulse driving heat transfer system, solid particles at the temperature of 200-1500 DEG C are used as heat transfer working media, and a solid particle high-temperature pulse driving pump is used as power to drive the high-temperature solid particles to move, so that transferring of heat energy is achieved. The solid particle high-temperature pulse driving pump is provided with a pulse cavity, and one part of the high-temperature solid particles at the temperature of 200-1500 DEG C are placed in the pulse cavity; a push plate is driven by a power device, so that the solid particles are pushed to move to leave the pulse cavity, and then a second part of solid particles enter the pulse cavity; the solid particles are driven in the pulse cavity again and again and transferred in batches, and thus pulse driving transferring is achieved. According to the solid particle high-temperature heat transfer and pulse driving heat transfer system, control over the temperature is achieved by arranging a temperature control cavity so that it can be guaranteed that the power device operates at a low temperature, the high-temperature particles can be transferred, and thus heat transfer at the temperature of 200-1500 DEG C is achieved.
