As the horizontal bioreactor of the thin layer with disturbance device that Race-way photobioreactor uses, the photo bio cultivated can experience sufficient disturbance with liquid, and then light can be received more uniformly, fully and then carry out photosynthesis, more uniformly absorb nutrition, improve photo bio and cultivate yield, it addition, photo bio can be discharged fully cultivate produced oxygen, aeration is more abundant.
Liquid is promoted to liquid dispenser 73 by pump 71 from reservoir 72, and liquid is assigned to the bioreactor 100 according to the application afterwards.In bioreactor 100, the photosynthetic microorganism in liquid obtains sufficient illumination, grows.After photo bio collection process, liquid is flow back to reservoir 72 again.Wherein reservoir 72 makes the minimum volume that can maintain liquid circulation, makes photosynthetic microorganism obtain illumination more fully, promotes its fast-growth.
Figure 11 illustrates a kind of alternative optical-biological reaction system 200, wherein use together with closed photo bioreactor according to the horizontal bioreactor of the thin layer of the application, closed photo bioreactor is positioned at the upstream of the horizontal bioreactor of thin layer, namely the liquid flowed out from closed photo bioreactor flows into the horizontal bioreactor of thin layer, existence due to disturbance device, the high-concentration oxygen produced in closed photo bioreactor can fully be discharged, and temperature is decreased sufficiently.It addition, such as above-mentioned culture efficiency and the collection efficiency that can also improve photo bio further.
Closed photo bioreactor in Figure 11 is shown as bank of tubes bioreactor 30 by exemplary table but it also may be other type of closed photo bioreactor.
Culture fluid is promoted to bank of tubes bioreactor 30 by pump 71 from reservoir 72.In bank of tubes bioreactor 30, the photo bio in liquid absorbs the nutrition in culture fluid, absorbing carbon dioxide, discharges oxygen.After bank of tubes bioreactor 30, carry the fluid of photo bio and the high concentration oxygen cultivated and be discharged bank of tubes bioreactor 30 and enter collecting tank 74, in collecting tank, the partial oxidation in liquid is released in air.Wherein collecting tank 74 makes the minimum volume that can maintain liquid circulation, makes photosynthetic microorganism obtain illumination more fully, promotes its fast-growth.
Along with fluid flows out collecting tank 74 and enters the bioreactor 100 according to the application, again return to reservoir 72.In bioreactor 100, on the one hand, photo bio obtains abundant illumination further growth, thus improving the cultivation amount of photo bio further；On the other hand, it does not have the oxygen discharged completely is discharged further fully, the temperature of fluid more quickly reduces；The third aspect, owing to being provided with disturbance device, the flowing of liquid is more unstable so that the photo bio cultivated is difficult to deposit, it is possible to collect efficiently.
So, except improve as except the advantage of Race-way photobioreactor, also solve oxyty from the fluid that closed photo bioreactor flows out excessive and can not discharge in collecting tank completely, fluid temperature (F.T.) is too high and occurs that microalgae deposition is unfavorable for the technical problems such as collection in liquid discharge process.
Only describe principles of the invention above by way of example, but be not meant to and limit the scope of the invention.On the contrary, structure described herein can be presented as other forms many.When not necessarily departing from the spirit and scope being defined by the below claims, above-described embodiment can be carried out various replacement and amendment by those skilled in the art.
