PHOTOBIOREACTOR FOR MICROALGAE CULTIVATION HAVING ARC-TYPE PARTITION STRUCTURE FOR FORMING VORTICES

The present invention relates to a photobioreactor for microalgae cultivation, which has a bubble-circulating structure in which a gas introduced into a cultivation space generates a vortex, thereby circulating microalgae and improving efficiency in cultivating the microalgae. The photobioreactor for microalgae cultivation according to one embodiment of the present invention includes: a cultivation panel body having a cultivation space therein such that microalgae can be fed therein and cultivated; a gas supply tube disposed in the lower portion of the cultivation panel body so as to transversely pass through the cultivation space, thereby discharging the introduced gas; and at least one vortex-generating partition which extends transversely from the inner wall of the cultivation panel body, wherein said at least one vortex-generating partition has an arc shape for generating vortices with respect to the ascending current of the gas supplied through the gas supply tube.
