Embodiment Construction

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like image 3 As shown, the present invention includes an outer ring heat absorbing pipe 1, an inner ring heat absorbing pipe 2, a sealing fin 3 ( image 3 (not shown), inlet header 4, intermediate header 5, outlet header 6, etc. Due to the small size of the sealing fins 3 relative to the entire heat sink, the image 3 It is not drawn in the example of , the specific structure of the sealing fin 3 can refer to the figure 1 and figure 2 . In this example, in addition to the absorption and reflection of the incident light from the sun outside the heat sink, the working fluid flow is also briefly described.

[0025] In this example, the solar heat absorber of the double row tube structure is a multi-faceted prism and an external light receiving type structure. Each heat absorber includes a plurality of heat absorption modules, and the ...

Abstract

The invention discloses a solar tower type heat absorber with a double-tube structure and a design method for the solar tower type heat absorber. The solar tower type heat absorber comprises necessary parts of outer ring heat absorbing tubes, inner ring heat absorbing tubes, a sealing fin and the like. According to the design requirements of the heat absorber, a certain gap is formed between two adjacent outer ring heat absorbing tubes or between the outer ring heat absorbing tubes and the inner ring heat absorbing tubes; the inner ring heat absorbing tubes are connected into a group through a closely-packed structure or a fin structure, so that sealing and heat transfer effects are achieved on sunlight received by the heat absorber. According to the solar tower type heat absorber disclosed by the invention, the wall temperature difference of phototropic surfaces and backlight surfaces of heat absorbing tubes is effectively reduced, the stress borne by the heat absorbing tubes can be reduced, the safety of the heat absorber is improved, and the service life of the heat absorber is prolonged; selection requirements on a heat absorber tube sub material can be reduced by reducing the front-rear wall temperature difference, so that the initial investment cost of the heat absorber can be greatly reduced. The heat absorber can improve heat flux density and average heat flux density allowed by the surface, so that the appearance dimension of the heat absorber can be reduced, and the efficiency of the heat absorber is improved.

Description

technical field [0001] The invention relates to a solar tower heat absorber with a double column tube structure and a design method thereof, belonging to the technical field of high temperature heat utilization of solar energy. Background technique [0002] Solar high-temperature thermal power generation technology is an important direction for large-scale utilization of solar energy, which 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 are water (steam), molten salt, air, heat transfer oil, liquid metal, other organic substances, etc. . Tower focusing has attracted the attention of many countries in the world due to its advantages of large capacity and high parameters. [0003] The tower thermal power generation technology i...
