Description
Technical field
The invention relates to a kind of outdoor temperature control microalgae photobiological reactive system, particularly relevant for the outdoor temperature control microalgae photobiological reactive system of growth conditionss such as a kind of temperature of regulating and control the photoresponse pipe by the water temperature and the depth of water of temperature control water tank and illumination.
Background technology
Because unicellular little algae (algae) can be by row photosynthesis stabilizing carbon dioxide, and convert thereof into organic-biological matter (biomass), these biomass energies are used for as the application of various technical fields, for example heath food, food additives, biochemical pharmacy, green energy resource, aquaculture, wastewater treatment etc.Use little algae to carry out advantages of application and be that little algae can constantly see through the capable photosynthesis conversion of luminous energy with carbonic acid gas and store into biomass, so can meet the environmental protection demand of continuous utilization.Producing grease (for example unsaturated fatty acids omega-3) with little algae is example, and it is under identical culture area, and little algae oil-producing capacity is 30 times of plantation conventional grease plant crop.Moreover the growth of little algae roughly only need be from carbon dioxide in air and sun power, and growth fast, and therefore annual crops has recyclability, reduces cost, reduces advantage such as industrial pollution with little algae production model often.
In order to satisfy the demand of the little algae of mass production, so the correlative study personnel are developed various bioreactor (photo-bioreactor), for producing various little algaes, wherein bioreactor can generally be divided into indoor culture system and outdoor breeding system.Described indoor culture system uses source of artificial light usually, the light source of incandescent light or photodiode (LED) for example, the outdoor breeding system directly uses sunlight as light source, and its cultivating system all roughly can be divided into closed photo bioreactor (closed photo-bioreactor) and open river streaming is cultured pond (raceway pond).
For example, the U.S. announces the 5th, 151, No. 347 patent of invention promptly discloses a kind of indoor type closed photo bioreactor, the advantage of this indoor type closed construction is growth conditionss such as easy Artificial Control light and temperature, but it also often is subject to the indoor finite space and module size can't be maximized, and comparatively expends light source electric power.In addition, TaiWan, China is announced M360557 number or M337972 number novel patent discloses streaming breed pond, the open river of a kind of indoor type, except possessing similar above-mentioned relative merits, this indoor type open configuration can provide lower equipment cost in addition, but, therefore relatively easily be subjected to contaminants such as koniology and may cause the difficulty of little algae when purifying because its water body is exposed in the room air.
On the other hand, for the outdoor breeding system,,, be beneficial to large-scale culturing micro-algae so help relatively the module in closed photo bioreactor or streaming breed pond, open river is maximized because the exterior space is bigger.For example, the U.S. discloses No. 2005/0260553 application for a patent for invention case and promptly discloses a kind of outdoor version closed photo bioreactor, compared to the indoor type closed construction, though being easy to module, this outdoor version closed construction maximizes, but, therefore be difficult to precisely control growth conditionss such as light and temperature because its closed conduct is arranged in outdoor open environment.Moreover, TaiWan, China is announced No. 519548 patent of invention and is disclosed streaming breed pond, the open river of a kind of outdoor version, compared to the indoor type open configuration, this outdoor version open configuration is exposed in the outside air because of its water body, so not only be difficult to precisely control growth conditionss such as light and temperature, be subjected to the contaminants such as dust in the outside air and cause the difficulty of little algae when purifying simultaneously also easilier.In addition, when if the too dark or little concentration of algae of the water body cultivation degree of depth is too high, sunlight can only shine cultures partly little algae of upper strata, pond, make the lower floor little algae of part can't effectively absorb luminous energy, thereby make culture efficiency reduce easily, or cause the little algae of levels to be in different growth phases and derive the problem that the biomass yield rate reduces.
So, be necessary to provide a kind of outdoor temperature control microalgae photobiological reactive system, to solve the existing in prior technology problem.
