Description
Technical field
The utility model is related to a kind of micro-algae large-scale culture apparatus, particularly high density Large-scale microalgae culture apparatus.
Background technology
Used as unicellular organism, which has a faster speed of growth than terrestrial plant to microalgae, microalgae energy effectively utilizes luminous energy,
CO2With inorganic salts synthetic protein, fat, carbohydrate and multiple high added value bioactivators, can pass through
Microdisk electrode is producing health food, food additives, feed and other chemicals.With the modem industrial plants mode of production,
On a large scale, low cost, efficient, the acquisition micro algae biomass of high-quality stable are premises.
The microdisk electrode form of current industrialized production application is open culture pond.Suction due to microalgae cell itself
Light and interception, the illumination depth in open pond are decayed with culture tank depth and microalgae density rapidly, and whole water body is presented
Go out surface highlights (typically only several millimeters or several centimetres, change), middle level low light level area with intensity of illumination and frustule concentration
Light and shade partitioned organization with bottom no light zone.The big portion's frustule in middle and lower part is in the low light level or dark space, it is impossible to obtain sufficient illumination,
Cell photosynthesis is weaker.Simultaneously as pedal agitating device is difficult to nutrient solution along optical path direction (above-below direction)
It is sufficiently mixed, the microalgae illumination of different depth is unreasonable, the microalgae cell long-time in culture pond top rests on intense light irradiation
The surface that penetrates, illumination are superfluous, and the frustule of the middle and lower part low light level or dark region is difficult to receive light by mixing arrival top top layer
According to therefore the culture pond culture efficiency of light energy utilization is low, and cell growth is slow, and area yield (refers to that unit takes up an area face microalgae newly-increased daily
Biomass) low, typically only 5-15g/m2/ d, causes large-scale culture floor space excessive.
The People's Republic of China (PRC) discloses a kind of utility model patent, Authorization Notice No.：CN 201110219548.A kind of
Micro algae culturing device, including：One open raceway pond, with a liquid outlet, the liquid outlet connects a liquid circulation pump, leads to
Cross the liquid-inlet of the liquid circulation pump connection culture liquid storage tank；The nutrient solution tank top has a liquid outlet conduit, makes training
Nutrient solution can flow back to open raceway pond through this pipeline.This is practical newly to suffer from the drawback that：
Still using pedal agitating device, nutrient solution is unable to the mixing of above-below direction to the utility model patent, meanwhile, volume
Much outer circulating pump and nutrient solution storage are filled, and increase cost.Installation fluorescent tube useless in device, it is not possible to carry out light filling, limits
The speed of growth of microalgae.
Content of the invention
The utility model is to provide a kind of simple structure, the highdensity micro algae culturing device of the convenient scale that cleans.
For solving above-mentioned technical problem, high density Large-scale microalgae culture apparatus of the present utility model, including raceway pond, institute
Raceway pond ovalize is stated, the raceway pond center is provided with a dividing plate, the raceway pond bottom is provided with a dewatering outlet；The runway
At the bottom of pond portion is provided with by the evenly distributed submarine light for constituting of some fluorescent tubes, is provided with two nutrient solution circulations in the raceway pond
Kinetic pump.
Further, the raceway pond upper end is open, and described dividing plate or so is respectively provided with a gas between two ends and raceway pond
Body distributor, the gas distributor are connected with ventilation pump by tracheae.
Further, quartz heating rod is provided with the raceway pond.
After said structure, compared with prior art, high density Large-scale microalgae culture apparatus is sufficiently mixed nutrient solution,
Microalgae is allow to carry out sufficient illumination；Meanwhile, phase microalgae density is big after incubation, and illumination not enough can be mended with fluorescent lamp
Light, reaches highdensity culture.
Description of the drawings
With reference to the accompanying drawings and detailed description the utility model is described in further detail.
Fig. 1 is the structural representation of high density Large-scale microalgae culture apparatus.
In figure：1 be raceway pond, 2 be dividing plate, 3 be nutrient solution circulation power pump, 4 be gas distributor, 5 be submarine light, 6
For dewatering outlet, 7 be quartz heating rod, 8 for ventilation pump, 9 be tracheae
Specific embodiment
As shown in figure 1, high density Large-scale microalgae culture apparatus of the present utility model, including raceway pond 1, the raceway pond
1 ovalize, is open on the raceway pond 1.A dividing plate 2 is provided with the middle of the raceway pond 1, and 1 bottom of the raceway pond is provided with
One dewatering outlet 6,1 bottom of the raceway pond are provided with by the evenly distributed submarine light 5 for constituting of some fluorescent tubes, and tunable optical is according to strong
Degree.The raceway pond is provided with vertically places quartz heating rod 7, it is ensured that the temperature of nutrient solution will not be too low.Set in the raceway pond 1
There are two nutrient solution circulation power pumps 3, drive nutrient solution flowing.One is respectively provided between 2 or so two ends of the dividing plate and raceway pond 1
Individual gas distributor 4, the gas distributor 4 are connected with ventilation pump 8 by tracheae 9.
The medium depth of the utility model middle-high density Large-scale microalgae culture apparatus raceway pond controls in 15-25cm,
The utility model high density Large-scale microalgae culture apparatus changes the agitating mode of nutrient solution and to the addition of fluorescent tube extra
Light filling, solve that microalgae cell illumination is insufficient and illumination not enough, hence it is evident that improve microalgae thin in open raceway pond
Born of the same parents' speed of production, cell concentration and culture efficiency, it will help solve efficiency/cost (investment, the fortune of microalgae large-scale culture
OK) bottleneck.
In present embodiment, using the open raceway pond of ellipse of two a length of 2 meters, a width of 1 meter, (culture area is 1.8
Square metre) SPIRULINA CULTIVATION is carried out, to be compared explanation.
One of raceway pond nutrient solution is highly 0.15m (270 liters of cumulative volume), and throughput is 0.3VVM, beforehand control
Pump capacity 12m3/ h, later stage can increase flow, daily 16h illumination, and 8h is dark, and night stops circulation.In cultivation cycle, put down
All temperature is about 25-30 DEG C.Initial frustule inoculum density is 0.4g/L, after culture 15d, sample analysis, and frustule concentration is
3.5g/L, converts into area yield for (culture end of a period frustule concentration-Initial seeding density) * nutrient solution cumulative volume (liter)/culture
Number of days/culture pool area=(3.5-0.4) * 270/15/1.8=31g/m2/d.
Using traditional training method as control, nutrient solution is highly 0.15m (cumulative volume to another open raceway pond
270 liters), throughput is 0.3VVM, and pedal stirring water velocity is 0.25 meter per second, and initial frustule inoculum density is 0.5g/
L, after cultivating 15d, sample analysis, frustule concentration are 1.9g/L, convert into area yield for (culture end of a period frustule concentration-first
Beginning inoculum density) * nutrient solution cumulative volume (liter)/cultivated days/culture pool area=(1.9-0.5) * 270/15/1.8=14g/
m2/d.
The microalgae area yield of the two methods result of the comparison explanation present invention improves 121.4%.
In above example, algae kind used is replaced with grid algae, chlorella, Chaetoceros, Phaeodactylum tricornutum, chrysophyceae or salt
Algae etc., repeats above-mentioned experiment, and acquired results are similar.
Although the foregoing describing specific embodiment of the present utility model, those skilled in the art should manage
Solution, these are merely illustrative of, and can make various changes or modifications to present embodiment, without departing from original of the present utility model
Reason and essence, protection domain of the present utility model are only limited by the claims that follow.
