Device for improving light receiving frequency of microalgae

The invention provides a device for improving the light receiving frequency of microalgae, and relates to the technical field of photobioreactors. A device for improving light receiving frequency of microalgae comprises a raceway pond, a partition wall vertically arranged in the raceway pond, and a plurality of microalgae conveying devices which are arranged in the raceway pond in a surrounding manner and have different heights. According to the application, the partition wall is arranged in the raceway pond, the microalgae conveying devices with different heights are arranged around the partition wall, and the microalgae in the dark area are directionally conveyed to the light area through the microalgae conveying devices, so that light-dark circulation of the microalgae is realized, the light receiving illumination frequency of the microalgae in the dark area is improved, and the utilization efficiency of light is improved. The multiple microalgae conveying devices are arranged around the raceway pond by a
