The present study developed a new ¡V typed Photobioreactor, ¡§ Automatically Temperature Controllable and Wave-Mixed Photobioreactor System, ATCWPS ¡§ . The main propose of the study is to reduce the energy consumption and production cost during the process of cultivation. It can be cut down the over-dependent of nature resource on the land and expand the ocean by using the advantage of the nature marine environment.
The Photobioreactor based on baffled tanks is investigated and the effect of the displacement of the Photobioreactor induced by external waves on liquid sloshing is discussed. The vortices generated by baffles can mix the fluid in the Photobioreactor. The influence of water depths and baffle height can be utilized to develop the model of Photobioreactor by simulating the inner change of energy, and to decrease the temperature of Photobioreactor with the characteristic of seawater specific heat. The problem of non-averaged light in the system by optical fiber system of total internal refraction is also improved in this work.
The result of the experiment made in the Shi-Hzuwan ( Bay ) aquaculture site shows the average temperature of algae liquid can be declined about 20%. The results of vibrating platform cultivation shows the baffled system can increase the energy of mixing micro-algae in the growing process. Optical fiber system of total internal refraction can enhance the light efficiency, and thus not only can improve the shading effect among algae, but speed up its growing rate. When the staggered baffles and the optical fiber system of total internal refraction are combined, the optimal result of the growth rate of algae can be obtained in this work.
