Description
Technical field
This utility model relates to technical field of microalga biology, and specifically a kind of step therein declines algae Photoreactor.
Background technology
Microalgae is the multiple high added value materials such as the organism that photosynthetic efficiency is the highest, rich in proteins, polyunsaturated fatty acid and carotenoid, and microalgae has absorbed nitrogen/phosphorus simultaneously, and accumulates the ability of oils and fats in incubation.Therefore, microalgae has a wide range of applications in all many-sides such as food, bait, feedstuff, environmental protection and bioenergies, and the most in recent years in terms of bioenergy, microalgae is considered as raw material prepared by the bio-fuels such as the biodiesel of most application prospect；Additionally, microalgae carbon sequestration and microalgae process the hugest rich in the potentiality of nitrogen/phosphorus waste water.
Bioreactor is the core apparatus that microalgae light autotrophy is cultivated.It is presently used for the bioreactor that microalgae light autotrophy cultivates and has open type and closed two kinds.
Open type microalgae culture system (raceway pond and circle pond) also exists simple in construction, builds the advantages such as easy, easy to operate and operating cost is low.But, open type pond also exists more shortcoming, as slow in frustule growth, algae cell density relatively low (usual algae cell density ＜ 1.0g/L), easily being affected by external environmental condition, condition of culture is difficult to control to, and is easily subject to the pollution of the harmful organisms such as protozoacide.Meanwhile, relatively low algae cell density can cause higher cost of gathering.Compared with open type microalgae culture system, closed photo bioreactor has condition of culture and stablizes controlled, frustule growth rate is fast and algae cell density advantages of higher, but closed photo bioreactor also exists investment, runs and the problem such as maintenance cost height and amplification difficulty so that they are difficult to large-scale application at present and cultivate in the light autotrophy of non-high added value microalgae (energy microalgae).Therefore, closed photo bioreactor is currently mainly applied to algal species cultivation and the cultivation of high added value microalgae (such as Haematocoocus Pluvialls) of microalgae.
The light path of bioreactor and unit volume illuminating area are the key factors affecting reactor performance.It is said that in general, light path is the shortest and the illuminating area of unit volume algae solution is the biggest, the performance of bioreactor is the most excellent, and the growth rate of frustule is the fastest, and algae cell density is the highest.At present, in open type pond, the algae solution degree of depth is usually about 15 ~ 30cm, and can fully accept the region of illumination only on the top layer of algae solution, the most several centimetres, most frustule is in dark space (light intensity is less than the minimum light intensity needed for frustule growth), illumination cannot be accepted fully, cause frustule to cannot be carried out photosynthesis and fast-growth effectively.Closed photo bioreactor, such as tubular type bioreactor, the light path of pillar bioreactor and flat plate photobioreactor is typically at about 5cm ~ 20cm.Compared with open type culture systems, the light path of closed photo bioreactor is relatively small, bigger than illuminating area.Although, frustule can obtain higher density in closed photo bioreactor, but the equipment investment of enclosed bioreactor is very big, and power consumption rate is high, it is difficult to scale is applied to the cultivation of general low value microalgae.Meanwhile, under higher algae cell density, light attenuation degree in algae solution increases, and is typically only capable of penetrating algae solution layer about 1-2cm.Therefore, the light path of closed photo bioreactor is the most excessive, and under higher algae cell density, major part frustule is limited by light still in dark space.
Amassing to increase the light receiving surface of microalgae culture system, improve the luminous energy that single algae cell obtains, some researcheres are taken measures on customs clearance and are transformed microalgae culture system.
In order to make full use of spatial light photograph to a greater degree, improve frustule and the utilization ratio of luminous energy, realize micro-algae large-scale, high density and the high efficiency of low cost are cultivated.Therefore, this area need nonetheless remain for a kind of simple, low cost and has the bigger Novel microalgae culture system than illuminating area.
