A refraction-based solar homogeneous tube reactor or dryer

Abstract

A refraction-based solar homogeneous tube reactor or dryer, which is composed of a plurality of cylindrical transparent hollow photorefractive media with a certain refractive index and a certain thickness. The surface, the inner surface of the innermost cylindrical transparent hollow light refraction medium and the adjacent cylindrical transparent hollow light refraction medium are covered with an anti-reflection film to reduce light reflection loss; the innermost cylindrical transparent hollow light refraction The inside of the anti-reflection film on the inner surface of the medium is the inner wall, and the inner wall is the inner reaction or drying cavity; from the outside to the inside, the relative refractive index of the cylindrical transparent hollow light refraction medium and air increases sequentially; When propagating in a hollow transparent cylinder, it is constantly deflected due to refraction, so that the circumferential light receiving angle is significantly increased, and the light distribution in the circumferential direction of the reactor or dryer is more uniform.

Description

technical field [0001] The invention relates to a solar tube reactor or dryer, in particular to a solar tube reactor or dryer based on the principle of refraction, having a larger circumferential light receiving angle and more uniform circumferential light energy distribution. Background technique [0002] With the increase of energy demand around the world, traditional fossil fuels are gradually decreasing, and the problem of environmental pollution has become increasingly prominent. The use of renewable energy has become an important means to solve the current energy demand and environmental pollution. Solar energy has the advantages of wide distribution, large reserves, clean and pollution-free, and is a typical renewable energy. Vigorously developing solar energy is of great significance to the sustainable development of human society. [0003] Solar photocatalytic hydrogen production is an effective form of using solar energy to realize energy conversion and solve the ...

AI Technical Summary

Problems solved by technology

[0006] 1) When sunlight irradiates the surface of the reactor or dryer, the light reflection is strong, resulting in a large energy loss;

[0007] 2) The circumferential acceptance angle of light in the reactor or dryer is limited (usually the part facing the light, the circumferential acceptance angle is ≤180°), and the energy distribution is locally concentrated and uneven, which cannot be applied to solar photocatalytic hydrogen production and material synchronization Uniform drying and other occasions that have high requirements on the uniformity of light distribution
