Description
Technical field
The present invention relates to CO2Fixed and algae culture technical field of bioengineering, more particularly to a kind of efficient multiphase
Mixed flat plate photobioreactor.
Background technology
Algae has high light and nutritional utilization efficiency, can be by water and carbon dioxide conversion at carbohydrate, pigment, albumen
The high values such as matter, fat organic compound can be used for that food, drug, nutriment etc. is made.In addition, handling waste water using microalgae
Exhaust gas and acquisition bio-fuel also have broad prospects.Use above field is required for large-scale bioreactor to carry out
Pilot scale culture.
Currently, commercial scale bioreactor is generally raceway pond open culturing.But open culture is with many
Disadvantage：1) light and utilization rate of carbon dioxide are low, 2) condition of culture is difficult to control, 3) production is easily subject to seasonal restrictions, and 4) culture solution
Vulnerable to pollution and by rainwater dilute or largely evaporated.
Closed photo bioreactor overcomes the drawbacks described above of Race-way photobioreactor, can control each growth
Parameter, and had the example of some pilot scale cultures.Closed photo bioreactor is generally divided into：Tubular type optical-biological reaction
Device, board-like bioreactor and column type bioreactor.But since closed photo bioreactor is complicated, amplification
Cost is higher, and the problem that illumination is insufficient, dead zone and temperature are excessively high is easy to happen for column type bioreactor；And tubular type light
Bioreactor is susceptible to that dissolved oxygen is excessively high, gas-liquid mixed is uneven and Xanthophyll cycle (refers to that luminous energy is more than that frond institute can profit
When quantity, photosynthetic function decline the phenomenon that.)；These can cause the biological concentration of culture and output capacity relatively low.For flat
If it can only increase the unit of reactor that the amplification of board-like bioreactor, which will overcome the above problem, existing technology, this
Sample can cause the sharp increase of amplification cost.In addition Photoreactor inner wall is easy to be adhered to by frond, so cleaning inner wall also makes a hemp
It is tired, it is unfavorable for amplification and industrialized implementation.
During all microdisk electrodes, illumination is to influence microalgae High Density Cultivation and limitation bioreactor to amplify
Most critical factor.The main design thought of bioreactor is that microalgae cell is enable to obtain sufficient illumination.Flat photoproduction
Although object reactor assembly improves illumination condition, but too short light path increases the difficulty of amplification, the amplification of reactor assembly
It can only be realized by increasing reactor unit, this adds increased the inputs of cost.And for the larger reactor of light path, although
Improve the utilization rate of light after using inner light source, but the arrangement mode of its inner light source can not be solved effectively in microalgae is attached to
The problem of illuminator covers, in addition complicated inner light source arrangement mode can also increase resistance, influence the cycle of algae solution, at the same there is also
Radiate difficult problem.
The research of algae culture is found：It is supported in the bioreactor of algae and under common cell density in scale,
Light can decay rapidly when being propagated in culture solution, and the penetration range of light is several millimeters, only have 1mm left under high-cell density
It is right.In fact it can be divided into dark space two parts with except close to the light area of plane of illumination in bioreactor, when light intensity is more than full
And value, the feelings of algae solution Rapid Circulation (frequency for being usually above 1Hz) between the light area close to light source and the dark space far from light source
Biological concentration and output have apparent increase under condition, and here it is so-called " flash effects ".
Utilize " flash effect " is then considered as how effectively reinforcing flowing of the algae solution in direction of illumination, JOrg Degen
Etc. designs a kind of flat plate photobioreactor (JOrg Degen, Andrea Uebele et al.A novel with baffle
airlift photobioreactor with baffles for improved light utilization through
The flashing light effect [J] .Journal of Biotechnol., 2001,92:89-94).Due in inside
It is added to polylith plate washer, flowing of the algae solution on direction of illumination can be effectively increased, and the document points out following for rule
Circulation is dynamic more to effectively utilize " flash effect " than irregular flowing.But multilayer baffle forms the algae solution of rising
Larger resistance makes energy consumption increase, simultaneously because internal structure complexity is also unfavorable for cleaning and amplification, similar Chinese patent with this
There is also the above problems by CN102260629.Above-mentioned flat plate photobioreactor is all logical for fairly large culture systems
It crosses and increases reactor unit come what is realized, less than 300L, this is greatly increased manufacturing cost maximum reactor unit volume.
