Abstract
The invention relates to a bushing-type high temperature heat storage device applied to solar heat utilization. The device is characterized by comprising an air inlet pipe, a heat storage room box body, a heat storage room door, an air outlet pipe, a first ventilation cavity, a second ventilation cavity, a heat storage material receiving pipeline, a coiled pipe, a heat storage material receiving pipeline support, a heat insulating material and a heat storage material, wherein the air inlet pipe is communicated with the first ventilation cavity positioned in heat storage space; the air outlet pipe is communicated with the second ventilation cavity positioned in the heat storage space; the coiled pipe is connected with a U-shaped pipe through an air flow pipeline; one end of the coiled pipe is communicated with the first ventilation cavity, and the other end of the coiled pipe is communicated with the second ventilation cavity; the heat storage material receiving pipeline is fixed with the air flow pipeline through the heat storage material receiving pipeline support; the heat storage material is encapsulated in the heat storage material receiving pipeline; and a heat transfer medium in the ventilation pipe is a gas. The bushing-type high temperature heat storage device has the advantages of simple structure, safety, reliability and high heat exchanging efficiency.
Description
technical field [0001] The invention relates to a sleeve-type high-temperature heat storage device applied to solar heat utilization. Background technique [0002] Solar energy utilization technology refers to the direct conversion and utilization technology of solar energy. Converting solar radiation energy into heat energy and utilizing it belongs to solar thermal utilization technology. Using the photovoltaic effect principle of semiconductor devices to convert solar energy into electrical energy is called solar photovoltaic technology. The history of human beings using solar energy can be traced back to 3000 years ago, but the history of actually using solar energy as a power and energy source is less than 400 years. [0003] my country's research on solar thermal power generation technology started relatively late, and some basic research did not start until the 1970s. The early research objects were mostly inorganic hydrated salts in phase change heat storage materia...
