PHOTOBIOREACTOR SYSTEM FOR HIGH-DENSITY CULTURE OF MICROALGAE

摘要

The invention discloses a photobioreactor system for high-density culture of microalgae which includes photobioreactor, and also includes solar collector, optical fiber, and illuminant device within the photobioreactor, residue gas absorption device, and medium separating recovery respectively connected with the photobioreactor. One end of the illuminant device is connected with spectrophotometric adjustment device, which is on the photobioreactor and connected with solar collector through optical fibers. Between the lower of the illuminant device and the bottom of the photobioreactor, there has a gas distributor, which is connected with the output of the gas mixing device. The system can increase the utilization efficiency of solar; reduce the consuming of external electrical energy. The system resolves the problem of sunlight using, such as intermittence, instability, and hard collection, so insures continually and stably culturing microalgae.
