Novel internal component and photobioreactor based on enhanced mixing along light direction

The present invention provides a novel photobioreactor and an internal component thereof. The photobioreactor comprises a transparent housing and multiple regularly arranged transparent baffle plates. The baffle plates are axially placed in the housing and tilt horizontally. A trapezoidal partial space is formed between the baffle plates. The photobioreactor enables fluid in a central area (dark area) of the reactor and fluid in a surface area (light area) of the reactor to rapidly and periodically circulate, thereby enhancing mixing of fluid along a radial direction (light direction) of the reactor.
