Solar tower type thermal power generation closed cavity type receiver and application method thereof

Abstract

The invention provides a solar tower type thermal power generation closed cavity type receiver and an application method thereof. The receiver comprises a tower body supporting frame, a heat collection receiver, a heat-insulation cover, a motion driver and a controller, wherein the tower body supporting frame supports the heat collection receiver; the heat collection receiver comprises a heat collection receiver shell and a heat collection receiver opening; the inner space of the heat collection receiver shell is a heat collection receiver cavity; the area of the heat-insulation cover is greater than that of the heat collection receiver opening; the heat-insulation cover is arranged outside the heat collection receiver opening; and the motion driver drives the heat-insulation cover to open or close the heat collection receiver opening under the control of the controller. By the solar tower type thermal power generation closed cavity type receiver, heat loss of the heat collection receiver can be effectively reduced in low temperature weathers and strong wind weathers, and the heat collection receiver can be prevented from being frozen.

Description

technical field [0001] The invention belongs to the technical field of solar energy applications, and in particular relates to a closed cavity receiver for solar tower thermal power generation and an application method thereof. Background technique [0002] Solar thermal power generation technology is one of the effective ways to solve environmental pollution and energy crisis in the 21st century. Solar thermal power generation mainly includes three methods: trough type, dish type and tower type. Among them, tower solar thermal power generation is the most economical form of power generation in large-scale solar power generation. [0003] For the tower solar thermal power generation system, the thermal receiver is the main component that absorbs solar radiation energy. The molten salt circulates inside the thermal receiver, and the thermal receiver uses the absorbed solar energy to heat the molten salt, and then melts the high temperature The thermal energy of the salt is ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, under low temperature and windy weather, the heat loss of the heat collecting receiver is serious, thereby reducing the power generation efficiency of the tower solar thermal power generation system; moreover, there is also the risk of the heat collecting receiver being frozen, making the heat collecting receiver not working
