Description
The present invention relates to photobioreactor fields, and in particular to a kind of stacked thin plate bioreactor.
Photosynthetic microorganism is that a kind of microorganism, including microalgae, cyanobacteria to be lived with light for solely or mainly energy source etc. is contained chlorophyll, can carry out photosynthetic microorganism.This quasi-microorganism has important biological utilisation value, especially microalgae, is rich in protein, can be used as aquatic feed or animal and fowl fodder (such as spirulina)；It is prior, certain microalgaes can largely synthesize secondary metabolites under given conditions, such as grease, carotenoid, polysaccharide, these substances are often the bioactive substance with high economic value, can be used in the fields such as functional food, food additives, pharmacy, bioenergy.Wherein, microalgae grease is extracted by microalgae large-scale culture, so be converted to liquid fuel, such as biodiesel is considered as solving one of bioenergy production and most important approach of carbon fixation and emission reduction.
Microalgae mass propgation has decades history, and current industrialization microdisk electrode is liquid submersion, i.e., algae is immersed in culture solution and is cultivated as the medium of micro algae growth using mass propgation liquid.Immersion culture mainly includes open culture pond and Closed photobioreactor (photo-bioreactor, PBR) two kinds of forms again.
The advantages of open culture pond is construction and operation, and cost is relatively low, however, liquid surface lower part frustule is weak by luminosity, bottom of pond cell is often difficult to receive abundant illumination, moreover, open pond takes up a large area, also need in culture using powerful agitating device and aerator.In addition, open culture pond is influenced very greatly, vulnerable to the pollution of bacterial body and pest and disease damage, to directly affect the growth and biomass proliferation of algae by external elements.
In contrast to this, closed PBR is usually used translucent material (such as glass, organic glass, plastic film) and the small container of optical path is made.Such as horizontal or vertical glass tube, the existing bioreactor of flat glass flume, illuminating area/volume of its cultivating system is bigger, and cell illumination is more abundant, and photosynthetic microorganism cell culture density is more open, and culture pond is higher, environmental condition controllability is strong, is less susceptible to external environment pollution.But closed PBR be equally also required to circulation agitating device, aerator,
And effective culture area of unit space volume is smaller.Moreover, the cost of such PBR usually its ontology is costly, operation expense is high; it is difficult to pilot scale culture; it is unable to reach ideal industrialization target, these are to realize the reason of most direct restraining factors of micro-algae large-scale industry and microalgae product cost are unable to reach popular consumption target.Meanwhile these traditional immersion training methods can not such as be delivered vegetables for the high-efficient culture of some special algae, nostoc and land for building dish due to that must use stirring, aeration, circulation machinery etc..
In addition, Closed photobioreactor is according to glass material, since glass container generallys use technological process for blowing; large-scale, suitable for large-scale production glass container is made, presently, there are very big technical difficulty, even the glass tube of middle-size and small-size test; its cost is also quite high; and during assembling, it will also be by many connection components, such as dedicated rubber connecting sleeve; connector; the breakage of glass tube or connection component, can also often occur in U-bend etc., and maintenance gets up also to have any problem.
It is above-mentioned open, closed since culture solution is ceaselessly being recycled and flowed, once the part of culture solution is contaminated, then fulminant pollution is generated within the scope of whole culture solutions quickly；And solid training method, porous material surface feed flow is given often through the liquid feed device at top, therefore not can avoid the fast propagation of pollution sources equally.
In addition, algae to be attached to the porous material surface that can adsorb and discharge moisture there are also the bioreactor of a kind of solid state rheology, by slowly supplying culture solution to porous material, for adhering to algae growth thereon.However this process for solid culture, the water retention property and algae attachment characteristic of porous material are often largely relied on, if material poor water retention property, needs ceaselessly to supply water, expends energy；And if algae adhesion is poor, algae is easily detached from, then can not make algae normal growth.These porous materials are often light-proof material, can adsorb more luminous energy, and algae is not high to the utilization efficiency of light, and porosity can also allow algae to enter and block duct in it, bring difficulty to subsequent feed flow, harvest, cleaning and disinfection.Moreover, the solid state rheology mode is often not properly suited for the biggish algae of volume, such as deliver vegetables, the culture of nostoc and land for building dish.
In conclusion existing bioreactor substantially exists the following technical problem: 1., the land occupation of open raceway pond it is big, culture density is low, and culture solution circulating consumption is high, vulnerable to outside contamination；2., closed light transmission container cost it is high, especially glass container is limited to the particularity of glass machining technique, can not one-pass molding, manufacturing cost, installation and maintenance cost are all very high, and it is low to equally exist cell density, space utilization degree is insufficient, the high problem of energy consumption.3., either open raceway pond or closed light transmission container, require consumption mass propgation liquid and energy, culture solution concentration is low when harvest, need to by cumbersome separation, filtering and the technological deficiency for being dried program, can not reduce microalgae product at
This.4. solid state rheology bioreactor, very big for the dependence of material itself, light utilization ratio is low, applicability also compares and is limited to, and liquid feed device is a kind of energy-consuming device, therefore can not further reduce toxigenic capacity.5. existing bioreactor is unfavorable for being effectively isolated and controlling for pollution sources.
Thus, the present inventor wants to provide that a kind of cost is cheap, the effective culture area of unit space volume is bigger, optical energy utilization efficiency is high, low energy consumption for culture, applicability is wide, harvest program simplification and the bioreactor suitable for the extensive industrialization culture of algae, so as to the whole production cost for reducing microalgae.

The illuminating area of bioreactor is one of the most key factor for evaluating bioreactor culture efficiency.In the following, identical nutrient solution volume is directed to, compared with so that stacked thin plate bioreactor of the invention is received the area of illumination with traditional both horizontal tube bioreactors, to illustrate the advantage of stacked thin plate bioreactor of the invention.
Receive the comparison of illuminating area:
Traditional horizontal tube bioreactor: 1L volume algae solution occupies the glass pipe that diameter is 50mm, is computed its light receiving surface product are as follows: 0.04m2。
Stacked thin plate bioreactor of the invention: 1L volume algae solution, liquid level thickness 3mm, double-side photic area are as follows: 0.66m2.As it can be seen that the algae solution of same volume, which receives illuminating area, improves about 16.67 times.
In order to further explain the advantage of bioreactor of the present invention, illustrate the advantage of bioreactor according to the present invention by way of example again below.
What is be contrasted with bioreactor according to the present invention is the horizontal tube pipeline bioreactor 200 provided in Fig. 4 with perspective view, and arrow indicates that culture solution flows into and out reactor 200.
With 200m2Occupied area for (Fig. 5-6 arithemetic unit is mm), as shown in figure 5, because to arrange with the matching used pump 210 and aeration tank 220 of reactor 200, can only arrange the horizontal tube pipeline bioreactor that 4 sets of such as Fig. 4 show.Assuming that the height of every set horizontal tube pipeline bioreactor is 2.5m, total volume of culture amount 4000L, in 10 days incubation times, with yield of biomass 3g/L calculating, dry matter 12kg is harvested altogether.
Equally in 200m2Occupied area in, as shown in Figure 6 use stacked plate TLC bioreactor according to the present invention, additional auxiliary facility as shown in Figure 5 is not needed, so 50 reactors 100 can be arranged.Assuming that the height of reactor 100 is similarly 2.5m, 20 specification of thin plate made of plate glass is 2.0 × 0.8m, and the spacing between adjacent sheet 20 is 10mm, each reactor
100 can be laminated 250 layers, each bioreactor culture area 400m2, then total culture area of 50 reactors 100 is 400 × 50=20000m2.Conservative estimation every square meter culture biological quality 1g/m daily2/ d, same cultivation cycle 10 days, then yield of biomass are as follows: 10d × 20000m2×1g/m2/ d=200kg.
From above-mentioned comparison, it is about 16.67 times for using the obtained yield of biomass of horizontal tube pipeline bioreactor using the stacked obtained yield of biomass of plate TLC bioreactor according to the present invention in the case where identical occupied area and space occupied.
With needing a large amount of water bodys, need a large amount of power consumptions come compared with conveying culture solution but also needing traditional duct type bioreactor of agitating device, stacked thin plate bioreactor according to the present invention is static gas wave refrigerator, a large amount of water body is not needed, without conveying or stirring operation in incubation, conveying and stirring power are saved, and illumination can be obtained well.In addition, culture solution concentration is significantly larger than traditional duct type bioreactor, therefore in links such as harvest, concentration, drying, water process, so that it may reduce a large amount of photo-biological-culture solution separation workload and energy consumption, to reduce overall cost when harvest, significant economic benefit is obtained.
Since the present invention started for the first time in incubation using static (not having to stirring), (Culture liquid measure is few for thin layer, light availability is high) training method, photosynthetic microorganism is placed in suitable Culture liquid measure and is cultivated, therefore it is highly suitable for the culture of volume and the biggish unicellular alga of form, including deliver vegetables, nostoc and land for building dish etc..
