Abstract
A refraction-based solar light homogenizing pipe type reactor or drier is formed by connecting a plurality of cylindrical transparent hollow light refractive media with a certain refractive index and a certain thickness in a tangent manner. The outer surface of the cylindrical transparent hollow light refractive medium on the outmost layer, the inner surface of the cylindrical transparent hollow light refractive medium on the innermost layer and the position between every two adjacent cylindrical transparent hollow light refractive media are coated with antireflection films so as to reduce light reflection losses. The interior of the antireflection film on the inner surface of the cylindrical transparent hollow light refractive medium on the innermost layer serves as an inner wall, and an inner reacting or drying cavity is formed in the inner wall. The relative refractive indexes of the cylindrical transparent hollow light refractive media are sequentially increased from outside to inside. When light spreads in all hollow transparent cylinders different in refractive index, the light deflects constantly due to the refraction action, the circumferential light receiving angle is increased remarkably, and distribution of the light in the circumferential direction of the reactor or drier is more even.
