Abstract

The invention discloses a focal spot adjusting method of a solar disc type condensation system. The method is characterized by comprising the following steps of: S1, sequentially setting a condenser, a color target, a point light source and a telescope of the solar disc type condensation system; S2, dividing a lens of the condenser into lens units, and keeping the one-to-one correspondence between the lens units of the condenser and the color gamuts of the color target; S3, observing the color target image reflected by the condenser through the telescope by an observer, and finding the lens unit corresponding to the color gamut deviating from the imaging rule; and S4, adjusting the found lens unit so that the color gamut deviating from the imaging rule is normally imaged. According to the invention, by adjusting the lens unit on the condenser deviating from the imaging rule, all lens units show normal and regular images as the normal imaging of color gamuts in the visual field of the observer, and the solar energy can be uniformly distributed on the focal plane of the condensation system.

Description

technical field [0001] The invention relates to the technical field of solar thermal power generation, in particular to a focal spot adjustment method of a solar dish-type concentrating system. Background technique [0002] Rotating parabolic concentrators in solar concentrating dish systems have shown great promise for competitive grid power generation and off-grid applications. The efficiency of this dish power system depends on the degree of light concentration. Most of the parabolic concentrating systems used are composed of many spherical or parabolic optical shape objects arranged in the shape of a parabola and installed on a support structure. These individual faces must be precisely aligned, as incorrect alignment can affect system performance and can create intense hot spots, which can reduce receiver life. In order to optimize the efficiency of a solar concentrating dish system, the flow distribution received by the receiver should be as uniform as possible. Co...
