Description

technical field [0001] The invention relates to a light heat collection device, in particular to a non-shielding light heat collection device. Background technique [0002] The current solar thermal power generation methods, the most common are tower, trough, butterfly and so on. Among them, the trough type is a relatively popular one, which is mainly composed of the following parts: light reflection and convergence structure, support structure, transmission control structure and system, and heat collection structure. Its light reflection and converging structure is mainly a parabolic reflective surface. The mathematical definition of the paraboloid is: a set of trajectories formed by a group of straight lines parallel to each other and perpendicular to the same plane passing through a parabola in the plane. This is a ruled paraboloid. Take one of the symmetrical sections as the mathematical model of the reflector parabolic reflector. A set of light reflection converging s...

AI Technical Summary

Problems solved by technology

[0004] First, because the heat collecting tube has to withstand high temperature, the structure is not simple, and it has a certain volume.

The shadow it produces affects the reflection efficiency and causes some heat loss;

[0005] Second, the entire parabolic reflector is produced in sections, and the process of each section is different, and the manufacturing cost increases accordingly

[0006] Third, the reflection efficiency of each segment is different, and there is still unevenness after convergence

[0007] Fourth, there are heat-collecting pipelines in the heat-collecting structure, and the heat-conducting medium flows in the pipelines, which is not easy to move and prone to failure

[0008] Fifth, a heat collection unit has not been standardized and modularized, which is not conducive to the yield, quality inspection and standardization of mass production

[0009] Sixth: Sunlight tracking must have a micro-control structure as a whole. Due to its own structure and control form, ordinary motors have certain difficulties and unreliability in starting, braking, fine-tuning, field protection, maintenance and lubrication, etc.

[0010] The disadvantage of the tower power station is that the construction cost is expensive. In addition, the solar tracking system requires high requirements, especially the investment in the heliostat field, which accounts for more than half of the entire investment due to the complexity of the tracking system.

The disadvantage of the butterfly power station is that the power is small and scattered

And when the large-scale cluster is used, the cost is relatively high
