Problems solved by technology

[0004] Since the light focused by the heliostat is concentrated on the center point of the focal spot formed on the receiving device during the process of concentrating light in the mirror field of the heliostat, the area close to the center point of the focal spot on the receiving device gets less light energy. However, the area away from the center of the focal spot gets less light energy, which leads to the uneven light received by the receiving device, making the local temperature of the receiving device too high, while the temperature of another part is too low, which in turn affects the receiving device. Certain impact on safety performance

Embodiment 1

[0034] Such as figure 1 As shown, the reflector arrangement structure in the tower power station provided by this embodiment includes at least two reflector units 1 arranged around the receiving device for reflecting sunlight to the receiving device. The reflector unit 1 receives A linear light extending along the height direction of the receiving device is formed on the device;

[0035] Wherein, the mirror unit 1 includes a main axis of rotation and a plurality of mirrors arranged on the main axis of rotation, and the projection point Q formed by the receiving device on the horizontal plane along the vertical direction is located on the projection line formed by the main axis of rotation on the horizontal plane along the vertical direction on the extension line. That is, the extension directions of the main axes of rotation in the mirror unit 1 all point to the projection point Q, and a plurality of mirror units 1 are arranged around the projection point Q with the projectio...

Embodiment 2

[0040] Such as Figures 2 to 4 As shown, the reflector arrangement structure in the tower power station provided by this embodiment includes at least two reflector units 1 arranged around the receiving device for reflecting sunlight to the receiving device. The reflector unit 1 receives A linear light extending along the height direction of the receiving device is formed on the device; wherein, the reflector unit includes a rotating shaft and a plurality of reflecting mirrors arranged on the rotating shaft, and the receiving device is formed on a horizontal plane along the vertical direction The projection point Q is located on the extension line of the projection line formed by the main axis of rotation in the vertical direction on the horizontal plane. And the linear light is within the receiving range of the receiving device.

[0041] Moreover, at least one annular arrangement area is formed in the direction from the inside to the outside of the projection point Q, and the...

Embodiment 3

[0058] Such as Figure 5 As shown, the tower-type solar energy utilization device provided in this embodiment includes the reflector arrangement structure in the tower-type power station in embodiment 1 or embodiment 2 and a device for receiving light reflected by the reflectors in the reflector arrangement structure. Receiver 2.

[0059] The tower-type solar utilization device provided by this embodiment, by setting the main axis of rotation in the mirror unit 1 as the extension of the projection line formed by the main axis of rotation on the horizontal plane, passes through the projection point formed by the receiving device 2 on the horizontal plane in the vertical direction , so that the reflector unit 1 forms a linear light extending along the height direction of the receiving device 2 on the receiving device 2, so that the receiving device 2 receives uniform illumination.

Abstract

The invention provides a reflector arrangement structure in a tower-type power station and a tower-type solar energy utilization device. The reflector arrangement structure comprises at least two reflector units which are arranged around a receiving device and used for reflecting sunlight onto the receiving device, wherein the reflector units form a linear light ray, which extends in the height direction of the receiving device, on the receiving device; each reflector unit comprises a rotating spindle and a plurality of reflectors arranged on the rotating spindle; and the projection point of the receiving device on a horizontal plane in the vertical direction is located on extension lines of the projection lines of the rotating spindles on the horizontal plane in the vertical direction. According to the reflector arrangement structure in the tower-type power station, provided by the invention, the linear light ray, which extends in the height direction of the receiving device, can be formed on the receiving device, so that the receiving device is enabled to receive uniform sunlight.

Description

technical field [0001] The invention relates to an arrangement structure of reflecting mirrors, in particular to an arrangement structure of reflecting mirrors in a tower-type power station and a tower-type solar energy utilization device. Background technique [0002] The solar tower power station is generally composed of reflectors, heat exchange medium storage tanks, high towers, receiving devices on the high towers, generators and other parts. Due to the high concentration multiple of the reflector structure, the receiving device can obtain higher Therefore, it has been widely promoted and applied. [0003] Among them, the layout structure of the reflector is generally to install multiple large-scale reflectors on a large-area site, usually called heliostats, and multiple heliostats are arranged to form a mirror field. Axis tracking system, and each heliostat is equipped with a tracking mechanism, so that the heliostat tracks the rotation of the sun, so that the sun's r...
