Description
Technical field
The utility model relates to bioreactor, particularly a kind of runway pond bioreactor of cultivating in order to the low-cost high-density mass-producing that realizes little algae.
Background technology
Little algae has important value of exploiting and utilizing, is widely used in aspects such as bio-pharmaceuticals, nutritious prod, healthcare products, bio-feritlizer, whole food processing, biological feed, WWT and production of renewable energy resources.Along with the exhaustion day by day of global fossil energy and the deterioration of environment, little algae receives various countries scientist's concern more as a kind of potential production of renewable energy resources person.
At present having realized that little algae kind of industrialization is less relatively, mainly contained tenaculat Habenaria, salt algae, Haematocoocus Pluvialls, Ke Shi Crypthecodinium cohnii and chlorella etc., broken through the low-cost high-density culture technique of little algae, is the key that realizes its industrialization.Little algae can be cultivated in bioreactor through being similar to the mode of microbial fermentation, and therefore a kind of bioreactor efficiently is a key equipment of realizing that micro-algae large-scale is cultivated.
The bioreactor that is used for little algae cultivation mainly contains open and closed two types.Closed photo bioreactor has the pollution of being difficult for, culture condition is easy to control, specific surface area height, luminous energy and CO
2Utilization ratio is than advantages such as height, but its investment and running cost are big, scale is amplified difficulty, has limited its widespread use in the existing modelling of little algae is cultivated.That the open type bioreactor has is simple in structure, amplify easily and low cost and other advantages, has been widely used in the large scale culturing of little algae.
Most typical open culture systems is the runway pond bioreactor by Oswald (1969) design; This reactor drum is light source with the natural light; Rely on the rotation of paddle wheel, make nutrient solution in the pond, mix, circulate, prevent the frustule deposition and improve its efficiency of light energy utilization.Generally, runway pond bioreactor is to be built into and the shallow pond of the slick ellipse of internal surface by cement.Only there is a bend in common runway pond, company is also arranged in order to increase volume of culture, changes the runway pond into many bends, and many bends can slow down runway pond water flows speed, influence the circulation of algae liquid.The degree of depth of nutrient solution is generally 15-25cm in the runway pond, the high about 40-50cm in pond.Usually has certain slope (100 meters runway pond, drop are 10 centimetres) at the bottom of the pond, to make things convenient for the cleaning in runway pond.
The runway pond is most popular in the world at present microalgae culture system, adopts the offshore company of runway pond bioreactor to have: U.S. PetroSun company, U.S. Aurora BioFuels company, U.S. PetroAlgae company, U.S. Cyanotech company, U.S. Cellana company, Mexico BioFields company, nz AquaflowBionomic company, Israel Seambiotc company, Britain AlgaeVS company etc.; Domestic corporation has: Jing Zhou astaxanthin ltd, ocean mouth greenery patches Energy Science Co., Ltd, Inner Mongol Jin Jiao group, Yunnan Green A Biology Engineering Co., Ltd, Jiaxing Daqi Biological Energy Co., Ltd., the good biotechnology of Dongying ltd, Beihai Kang Yuan biotechnology Ltd, Fujian Province Shenliu Health Food Co., Ltd, the strong biotechnology ltd in Guangdong, Jiangmen, the little algae of Hainan Di Aisheng (DIC) ltd, Yunnan unicorn jade for asking rain both culturing microalgae ltd etc.
Though raceway pond microalgae culture system is studied mechanism and company extensively adopts, its production efficiency is generally lower, and generally, the biomass concentration of breed only has 1.0gL
-1About, far apart with high-density culture, and the lower cell density cost that can cause gathering significantly increases.Many shortcomings to traditional runway pond bioreactor; " the open pond of low head and method of use and the purposes that are used for large-scale culturing micro-algae " (Chinese patent of Cong Wei etc.; CN101948740A) existing runway pond is improved; " drop effect " introduced in the reactor design, realized that the shallow-layer of little algae is evenly cultivated, improved algae cell density, reduced water body driving energy consumption." a kind of production equipment of industrialization culturing microalgae " (Chinese patent of Cai Zhiwu; CN201245640Y); The main body of this culture apparatus is runway pond formula structure (not possessing stirring rake), and its mode through air-blowing realizes the circulation of algae liquid, and open pond covers with plastics film fully; This reactor drum combines open and closed photo bioreactor advantage separately, and the author claims to realize that the existing modelling of the little algae of produce oil cultivates.
Though above-mentioned improvement project is in the production efficiency that has to a certain degree improved runway pond bioreactor, it and the unresolved core technology problem that influences runway pond bioreactor production efficiency,, luminous energy little and CO like specific surface area
2Low, the easy pollution of utilization ratio, Cycle Difference, environment controllability poor (temperature, illumination, pH) etc.The utility model patent proposes the plan of the open bioreactor of a kind of novel combination to above-mentioned technical problem, cultivates in order to the low-cost high-density of realizing little algae.
On the whole, traditional runway pond bioreactor that present scientific research institution and enterprise are adopted, there are many shortcomings technically in it:
When (1) utilizing traditional runway pond bioreactor culturing microalgae; Light is difficult to penetrate the liquid layer of 15-30cm, particularly along with the increase of algae cell density, a little less than the penetrativity of light becomes more; Cause the frustule of nutrient solution lower floor can't accept competent illumination, its growth is suppressed;
(2) the effective temperature control of traditional runway difficult realization of pond bioreactor during high temperature season, utilizes water-cooled or air-cooled mode to cool off algae liquid, and energy consumption is huge, and has territorial restrictions (low temperature seawater), and low temperature season and rainy season are difficult to culture;
(3) traditional runway pond bioreactor pollutes other assorted algaes, bacterium, fungi, protozoon or virus etc. in process of production easily, can cause when serious to culture failure;
When (4) utilizing traditional runway pond bioreactor to carry out both culturing microalgae; Frustule is lower to the utilization ratio of carbonic acid gas; The runway pond belongs to open bioreactor, and little algae can freely absorb carbon dioxide in air, but the concentration of Carbon Dioxide in Air lower (≈ 0.03%); Be difficult to satisfy little algae needs of growth fast, carbonic acid gas becomes one of principal element of restriction micro algae growth;
(5) algae liquid Cycle Difference in the bioreactor of runway pond, frustule light dark space switching speed is slow, influences the growth of little algae.
Based on above-mentioned defective, existing runway pond bioreactor is difficult to effectively realize the micro-algae large-scale cultivation, is necessary to design a kind of new runway pond bioreactor scheme.
