In order further to improve insulation and control thermal property, in an embodiment of the utility model, pooled storage 4 is processed by thermal insulation/lagging material, for example, and pottery etc.
In addition, in a preferred embodiment of the utility model, concentrate temperature-controlling chamber 2 to be arranged on underground in the greenhouse 1, so also can further improve the insulation of concentrating temperature-controlling chamber 2 and control thermal property.But, note that the utility model is not limited to this embodiment, concentrate temperature-controlling chamber 2 also can be arranged on the ground or be arranged on the outside in greenhouse 1.
In order to have guaranteed that sufficient sunlight injects in the greenhouse 1, in an embodiment of the utility model, the wall of the one side that faces south at least in greenhouse 1 or/and the roof partly or entirely be to process by light transmissive material, for example, glass or plastics.
In an embodiment of the utility model, what culture vessel 3 can be in coiled container, flexible thin membrane type container, plate shaped container or the runway pond formula container is at least a.
In another embodiment of the utility model, be provided with light compensating apparatus in the culture vessel 3, for example the LED lamp is used for when extraneous sunlight is not enough, and the photosynthetic microorganism in culture vessel 3 replenishes light, promotes its growth.
In another embodiment of the utility model, can be provided with aerating apparatus in the culture vessel 3, be used to stir the photosynthetic microorganism nutrient solution and supply its growth required gas to the photosynthetic microorganism nutrient solution, for example, CO
2Gas.
To combine a concrete application example to specify the utility model below.
[instance]
This instance is primarily aimed in northern greenhouse mass-producing both culturing microalgae.Greenhouse 1 adopts the glass heliogreenhouse, and the internal space for example can be 500m
3, culture vessel 3 for example can be the tubular type bioreactor, its cubic capacity can be 2m
3, culture is that little algae, total internal space of concentrating temperature-controlling chamber 2 can be 4m
3, be lined with warming plate all around.Pooled storage 4 can be 2.5m
3Sugared porcelain storage tank.Little algae optimum growth temperature can be 15 ℃-25 ℃, and tolerable temperature can be 5 ℃-40 ℃, with one month November culture experiment be example.
Daytime the 9-10 point, temperature can reach about 15 ℃ in the glasshouse, this moment, the algae liquid that is stored in the pooled storage 4 was delivered in the tubular type bioreactor 3 via pipeline 5 with pump 6, in greenhouse 1, carried out photosynthesis; Afternoon, 4-5 o'clock greenhouse 1 interior temperature was lower than 15 ℃, opened valve 7, made algae liquid under action of gravity, 5 flow to voluntarily in the pooled storage 4 by the road.Concentrate temperature-controlling chamber 2 heat to be provided, the algae liquid temp is controlled at about 10 ℃ by earth source heat pump.After temperature rises to the optimal temperature of micro algae growth in the next day 9-10 point glasshouse 1, again the algae liquid pump in the pooled storage 4 is gone in the bioreactor 3 in the greenhouse 1 to culture.
Compare with control group (adopt the heat pump air conditioner heating, temperature maintains about 20 ℃ all the time), central heating mode energy consumption is 0.5% of a control group, and output improves 7%.
Cultivating microalgae is concentrated in the mass-producing in winter; Reduced the temperature control space greatly, reduced area of dissipation, reduced heat-conduction coefficient with respect to prior art; Reduced the conversion of heating-amount, reduced heating energy consumption, thereby a nearly step is reduced the aquaculture cost of little algae to environment potential energy direction; On the other hand, but dark, low temperature, high dissolved oxygen environment have little algae respiration to effect, help the accumulation of culture living weight.
Compared with prior art, the utility model has the following advantages at least:
1, the utility model comprises a concentrated temperature-controlling chamber, is positioned at the underground of greenhouse, and being used in the greenhouse when outside temperature is lower than algae liquid suitable growth temperature is that algae liquid is concentrated insulation or temperature control.
2, comprise pooled storage, be positioned at and concentrate temperature-controlling chamber, be used for the algae liquid of centralized stores insulation or temperature control process.
3, the present invention avoids the energy input to culture environment of living in culture collection central heating and refrigeration together, and the utilization of energy is more effective.
4, together, place dark, low temperature, high dissolved oxygen environment effectively to press down, increase the culture biomass accumulation to the culture respiration with culture collection.
Though in conjunction with accompanying drawing the utility model is illustrated, disclosed embodiment is intended to the utility model preferred implementation is carried out exemplary illustration in the accompanying drawing, and can not be interpreted as a kind of restriction to the utility model.
Though some embodiment of this overall utility model design are shown and explain; Those skilled in the art will appreciate that; Under the situation of principle that does not deviate from this overall utility model design and spirit; Can make a change these embodiment, the scope of the utility model limits with claim and their equivalent.
