1. closed photo bioreactor that improves the efficiency of light energy utilization that microalgae mass cultivates, it is characterized in that:

  • the inner-wall surface at the plane of illumination of closed photo bioreactor is provided with 2 baffle plates perpendicular to the nutrient solution flow direction at least, and nutrient solution that zone between the baffle plate the covers bioreactor effectively part or all of zone of plane of illumination that enters the mouth between the outlet is set;

    Described closed photo bioreactor is board-like bioreactor, circular pipe type bioreactor or ellipse tube type bioreactor;

    The length of the baffle plate in the described board-like bioreactor be in the board-like bioreactor nutrient solution width of flow path 30%~

    100%;

    The length of the baffle plate in described circular pipe type bioreactor or the ellipse tube type bioreactor be nutrient solution runner plane of illumination the cross section arc length 30%~

    100%.
