Abstract

The invention discloses a thermal insulation structure of a thermal medium storage tank and a thermal medium pipe of a solar photo-thermal power generation system. The thermal insulation structure comprises thermal insulation composite layers, fixed parts, support strips and an outer protecting layer. All groups of thermal insulation composite layers are sequentially wrapped on a tank body of the thermal medium storage tank or the peripheral surface of the thermal medium pipe group by group according to a sequence from inside to outside. The support strips are fixed outside the thermal insulation composite layer of the outermost side in a surrounded mode along the circumference and are one layer or two layers of stacked aerogel strips of 1-3cm in thickness; and the support strips are parallelly arranged on the thermal insulation composite layer of the outermost side at intervals of 0.5-1.0 meter. The outer protecting layer is wrapped on the outer side of the support strips, and an annular cavity is formed between the outer protecting layer and the thermal insulation composite layer of the outermost side and is an air thermal insulation layer. According to the thermal insulation structure, a mode of jointly utilizing the thermal insulation composite layers and the air thermal insulation layer on the outer surface of the tank body or the pipe is adopted, thermal insulation effect is remarkable, and cost of the air thermal insulation layer is extremely low.

Description

technical field [0001] The invention relates to the field of thermal insulation, in particular to thermal medium storage tanks and pipeline thermal insulation structures of solar thermal power generation systems. Background technique [0002] Solar thermal power generation refers to the use of large-scale arrays of parabolic or dish-shaped mirrors to collect solar heat, provide steam through heat exchange devices, and combine traditional turbogenerator technology to achieve the purpose of power generation. [0003] The theoretical advantages of solar thermal power generation are: thermal energy accounts for more than 60% of solar energy, and solar thermal power generation directly outputs AC power. The cost of solar thermal power generation is lower than that of photovoltaic power generation with silicon cells, and solar thermal power generation is suitable for high-power development. The use of solar thermal power generation technology avoids the expensive silicon crystal p...
