摘要:
A light-catalyzed reaction system by collecting sunlight mainly comprises a light collector, a light conduction device, and a light transmitting reactor capable of transmitting full-spectrum rays of sunlight. The light collector is fixed at the free end of a two-degree-of-freedom bracket formed by connecting a pitching main shaft to an orientation main shaft, and the orientation main shaft and the pitching main shaft can be driven respectively by separate servo motors to relatively rotate to track the sun. Multiple layers of light-collection convex lens groups are disposed on the light collector, and converging rays formed by transmission and convergence of collected sunlight through the light conduction device are directed to the light transmitting reactor. The light transmitting reactor comprises a light transmitting cylinder and a sealing cover. The sealing cover is arranged on the light transmitting cylinder, and the light transmitting cylinder is filled with a reaction solution. The system is applied to processes of light-catalyzed hydrogen production and light-catalyzed methyl alcohol and oxygen production.
