Abstract

The invention relates to a heat insulation structure of a solar thermal power generation high-temperature molten salt storage tank, which comprises a heat insulation layer, a reflecting layer, a composite functional layer and a protective layer. The reflecting layer is a polished aluminum foil (plate) or a stainless steel foil (plate), and the composite functional layer is made of phenolic aldehyde, polyurethane or tripolycyanamide by means of integral foaming. The invention further provides a preparation method for the heat insulation structure and application of the heat insulation structure. The heat insulation layer and the reflecting layer are constructed layer by layer, a support ring of the protective layer is machined according to the shape of the storage tank, and the protective layer serves as a formwork for casting the composite functional layer, so that the heat insulation structure of the storage tank is formed. The heat insulation structure of the storage tank is excellent in heat insulation effect and long in service life.

Description

technical field [0001] The invention relates to a high-temperature energy storage technology for solar thermal power generation, in particular to a technology for a thermal insulation structure in a high-temperature molten salt energy storage system for solar thermal power generation. Background technique [0002] The depletion of fossil energy and the deteriorating environment have become long-term and major bottlenecks restricting the development of the global economy and society, and affecting the living conditions of human beings. In order to solve this problem, on the one hand, it is necessary to make scientific, economical, efficient use and development of fossil fuels, and on the other hand, it is necessary to accelerate the development and utilization of renewable energy. Solar energy has attracted widespread attention due to its wide distribution and abundant reserves. Vigorously developing and utilizing solar energy will change my country's energy shortage and unr...
