Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0042] figure 1 It shows the flow of a manufacturing method of a curved cylindrical reflective concentrator for a line-focusing solar system, including the following steps: original sheet selection, support setting, thermal bending and annealing, glass cutting, surface roughness detection and use Clustering, optical path detection and size clustering, applying concentrated loads.

[0043] Selection of the original film: select the mirror-grade 3.2mm thick float glass 1 as the original film for processing. Glass below 3mm and above 14mm is not suitable for processing the original film of the condenser lens. Choose thinner glass within this range to reduce radiation absorption loss and obtain a smaller focal length to aperture ratio. After cleaning and drying the original glass sheet, randomly select 10 measuring points per square meter on th...

Abstract

The invention relates to a method for manufacturing a flexure cylindrical mirror condenser for a line-focus solar system, which comprises the following steps of sheet selection, support arrangement, hot bending and annealing, glass cutting, surface roughness detection and clustering, light path detection and clustering, and application of fine tuning concentrated line load, wherein the inside of a hot bending furnace is provided with a support capable of making glass rotate freely so as to prevent the glass from generating bending moment adverse to glass forming on the support saddle position. The manufacture method can improve the condensing effect, simplify the processing technology and reduce the manufacturing cost.

Description

technical field [0001] The invention relates to a method for manufacturing a concentrating mirror, in particular to a method for manufacturing a deflected cylindrical reflective concentrating mirror for a line-focusing solar system, and belongs to the technical field of solar energy utilization. Background technique [0002] Energy is an important material basis for the development of the national economy and the improvement of people's living standards. With the sustained and rapid economic growth, the limited resources of fossil energy and the environmental problems caused by development and utilization have increasingly become constraints to the sustainable development of the economy and society. factor. Accelerating the development and utilization of renewable energy is an important way and measure to solve energy and environmental problems. Solar energy is a clean, non-polluting and inexhaustible energy source. It is one of the fastest growing renewable energy sources,...
