A preparation method of a solar dish system with a heat storage device

Abstract

The invention relates to a manufacturing method for a solar disc type system with a heat storage device. By means of the technical scheme of the method, the optimal position connecting relation among a base, an inclined heat collecting pillar, an energy storage box and a Stirling engine is given out, the problem that in the prior art, a disc frame is top-heavy is solved, and the load of the disc frame is also greatly reduced. Meanwhile, a certain inclination angle exists between a center shaft of the base and the heat collecting pillar relative to the center shaft of the base, so that heat can be better collected by a heat collector at the top end of the heat collecting pillar, and the heat collecting efficiency of the whole system is improved. The Stirling engine is arranged on one side of a heat storage box so that the heat dissipating problem of the Stirling engine can be well solved. In addition, a graphite layer serves as a material for heat collecting and conducting, sodium sulfate for capacity expanding and quantity increasing serves as an inorganic matter phase-change heat storage material, and the Stirling engine can be in a stable working state all the time.

Description

technical field [0001] The invention relates to a preparation method of a system capable of prolonging the power generation time of solar dish-type power generation equipment, in particular to a preparation method of a solar dish-type system with a heat storage device. Background technique [0002] The application of low-cost and high-performance heat storage technology is the biggest advantage that solar thermal power generation can compete with photovoltaic power generation. Since the large-scale development of solar thermal power generation began, heat storage has played an important role in it. Over the past few decades, heat storage technology has also undergone evolution, but so far, molten salt heat storage is still the most cost-effective and mature heat storage technology. But what we still need to see is that emerging heat storage technologies are also gradually developing. [0003] The older Ruths heat storage technology, also known as steam heat storage, stores...
