Embodiment
Understand more specifically for having technology contents of the present utility model, feature and effect, now by reference to the accompanying drawings, details are as follows:
As shown in Figure 1, 2, the U-shaped raceway pond bioreactor of packaged type of the present embodiment, includes: raceway pond 1, aeration tube 2, plug-flow pump 3, air pump 4, micro-algae subsider 5, micro-algae receiving tank 6 and support 7.
Raceway pond 1 is U-shaped, and bottom surface is arc surface, and the central angle of arc surface is 120 °, and raceway pond sidewall is two planes, and these two planes connect with circular arc respectively, and tangent with the circle at circular arc place.The upper surface sealing of raceway pond 1 is coated with transparent film.
Mid-way erection bottom raceway pond 1 has aeration tube 2, for raceway pond 1 inner homogeneous air feed.Aeration tube 2 is evenly distributed with the solarization air cap (figure does not draw) of diameter 2 millimeters, the external air pump 4 of aeration tube 2.
In raceway pond 1, erection has 2 plug-flow pumps 3, for driving algae liquid in raceway pond 1 at raceway pond 1 internal circulation flow.
The sidewall of raceway pond 1 offers the outlet of algae liquid.The external micro-algae subsider 5 of this algae liquid outlet, this micro-algae subsider takes the shape of the letter U, and bottom surface is arc surface.Micro-algae receiving tank 6 is connect after micro-algae subsider 5.Described micro-algae subsider 5 for receiving the algae liquid of discharging from raceway pond 1, and falls to after bottom micro-algae subsider 5 until micro-algae, and micro-algae is entered micro-algae receiving tank 6.Micro-algae that described micro-algae receiving tank 6 is discharged for collecting micro-algae subsider 5.
Support 7 adopts zinc-plated square tube to make, for supporting and fixing raceway pond 1.This support 7 is detachable, to facilitate the dismounting of bioreactor, assembling, movement.
The U-shaped raceway pond bioreactor of above-mentioned packaged type is when for both culturing microalgae, rise under buoyancy from aeration tube 2 bubble out, liquid is around driven to form one upwelling, algae liquid in raceway pond 1 Homogeneous phase mixing under the effect of this strand of upwelling, thus effectively prevent the attached wall phenomenon of micro-algae on raceway pond 1 surface.Meanwhile, plug-flow pump 3 drives the algae liquid in raceway pond 1 overall at raceway pond 1 internal recycle, which improves optical energy utilization efficiency and the culture density of microalgae cell.Because the sealing of raceway pond 1 upper surface is coated with transparent film, thus be formed as sealed raceway pond bioreactor, decrease the evaporation of moisture and the pollution of dust in air.During to microalgae harvesting, algae liquid is entered micro-algae subsider 5 from the algae liquid outlet of raceway pond 1, after micro-algae sedimentation, the more micro-algae fallen to bottom micro-algae subsider 5 is entered micro-algae receiving tank 6.
