Embodiment 1
[0026] Such as figure 1 As shown, the vertical heat-absorbing panels in the current tower-type heat absorber are single-row radiation heat-absorbing tube panels perpendicular to the ground, which are generally arranged in a single row. When the light reflected by the heliostat shines on the heat-absorbing panel , part of the light is not absorbed by the heat-absorbing screen but is reflected, so the heat-absorbing device is very bright when viewed from a distance, and when the temperature of the heat-absorbing screen is high, its radiated heat is a large loss.
[0027] Such as Figure 2-5 As shown, it is a new type of tower-type photothermal power station heat absorber of the present invention, the heat absorber is composed of a plurality of heat absorber units 1, and the plurality of heat absorber units 1 are arranged along the direction of the tower circumference, in the form of Circular or polygonal, the heat absorber unit 1 includes: a first heat absorbing tube panel 11, ...
Embodiment 2
[0030] Such as Figure 6 As shown, this embodiment is basically the same as the above-mentioned embodiment, the only difference is that a third heat-absorbing tube panel 13 is provided on the side opposite to the first heat-absorbing tube panel 11 of the second heat-absorbing tube panel 12, The third heat-absorbing tube panel 13 includes a plurality of third tube bodies 131 arranged at equal intervals, and the number ratio of the third tube bodies 131 to the second tube bodies 121 is 1:1.5˜1:4.
Embodiment 3
[0032] Such as Figure 7 As shown, this embodiment is basically the same as the above-mentioned embodiment, the only difference is that a fourth heat-absorbing tube panel 14 is also provided on the side opposite to the second heat-absorbing tube panel 12 of the third heat-absorbing tube panel 13, The fourth heat absorbing tube panel 14 includes a plurality of fourth tube bodies 141 arranged at equal intervals, and the ratio of the number of the fourth tube bodies 141 to the third tube bodies 131 is 1:1.5˜1:4.
