Abstract

The invention provides an anti-wind device for a tower type solar heat receiver. The anti-wind device for the tower type solar heat receiver is arranged on the tower type solar heat receiver placed vertically, and comprises clapboards with sunlight transmission functions, wherein the clapboards are vertically placed and uniformly distributed along the circumferential direction of the tower type solar heat receiver; each clapboard is arranged at a breaking part between two heating surface pipe panels in the tower type solar heat receiver; and the clapboards and the tower type solar heat receiver are fixed through a fixing device. According to the anti-wind device for the tower type solar heat receiver provided by the invention, the air convection flowing along the circumferential directionof the tower type solar heat receiver is limited in a space partitioned by each two adjacent clapboards, so that the action range of the air convection flowing on the circumferential direction of thetower type solar heat receiver is reduced, the air convection motion along the whole circumferential direction of the tower type solar heat receiver is prevented, and finally the convection heat losscaused by the horizontal convection motion of air on the tower type solar heat receiver is reduced. The device is simple in structure, light in weight, low in support requirement, and convenient to install, maintain and replace.

Description

technical field [0001] The invention relates to a windproof device for a tower-type solar heat absorber, belonging to the technical field of tower-type solar thermal power generation. Background technique [0002] Solar high-temperature thermal power generation technology is an important direction for large-scale utilization of solar energy, and it has far-reaching significance for human beings to solve problems such as fossil energy crisis and air pollution. According to different focusing methods, solar high-temperature thermal power generation can be divided into three types: dish type, trough type, and tower type; the working fluids used include water (water vapor), molten salt, air, heat transfer oil, liquid metal, and other organic substances, etc. . The tower focus has attracted the attention of many countries in the world due to its advantages of large capacity and high parameters. [0003] Tower-type thermal power generation technology is already in the initial st...
