Description
Technical field
The present invention relates to a kind of bioreactor for cultivating algae, and in particular to a kind of runway suitable for sunlight batch production
Formula bioreactor, the reactor is applied to Isochrysis galbana, Phaeodactylum tricornutum, Chaetoceros gracilis, Chaetoceros muelleri, rain and gives birth to red
The pilot scale culture of the various microalgaes such as ball algae.
Background technology
Microalgae can effectively utilize luminous energy, CO2With inorganic salts synthetic protein, fat, carbohydrate and various high
Added value bioactivator, can produce health food, food additives, feed, bio-feritlizer, change by microdisk electrode
Cosmetic and other natural prodcuts.In addition, in recent years using algae for the production of the gene outcome of host is also of increasing concern.It is micro-
The exploitation of algae living resources makes up the not enough and limitation of conventional crop for slowing down soil, environment, the energy and population crisis,
And promote traditional agriculture all to have great importance to industrialized production transition.As the mankind constantly add to the understanding of microalgae
Deep, exploitation and development of new high-efficiency photobioreactor and its application study in terms of the High Density Cultivation of microalgae have turned into micro-
One important component of algae biotechnology.At present, micro algae culturing device mainly has open and closed two kinds of photo-biologicals
Reactor.
Race-way photobioreactor be widely used in commercialization microalgae large-scale culture in, it have small investment, into
The advantages of this is low, technical requirements are simple, mainly there is four types：On-swimmer's pool, circulatory pool, runway pool, pond.Wherein most allusion quotation
Type, the most frequently used open pond culture systems are the raceway pond reactor (race-way of Oswald designs
Photobioreaccor), floor space is small, pollution is few, with natural light as light source and thermal source, improves the luminous energy of frond cell
Utilization rate, obtains good effect in the large-scale culture of spirulina, chlorella and salt algae；But, open photo-biological is anti-
Device is answered easily to be affected by the external environment, it is difficult to keep convenient temperature and illumination；Also, dust, insect and miscellaneous bacteria can be subject to
Pollution, be difficult to keep high-quality single algae to cultivate；Additionally, luminous energy and CO2Utilization rate is not high, it is impossible to realize High Density Cultivation.
Solix companies of the U.S. develop a kind of frivolous film hanging bag type microalgae culture system of water, are a kind of closed photo things
Reactor, hundreds of meters Pig long is suspended in pond, another on the one hand for the pressure-bearing for helping the buoyancy of water to mitigate plastic foil
Aspect can also be used the water in pond to realize the temperature buffer of Pig culture systems；But the bearing strength of plastic foil is low, leads
Such plastic foil Photoreactor is caused to be difficult to amplify.Additionally, traditional closed bioreactor there is also costly, investment
Greatly, it is high using artificial built-in light source and thermal source, power consumption, can cultivate that algae kind is single, late stage of culture is limited due to the rising of cell concentration
Light processed is penetrated so as to reduce light efficiency, the shortcomings of in incubation cell is sustained damage due to hydraulic pressure increase.
The content of the invention
The technical problems to be solved by the invention are directed to the deficiencies in the prior art, and provide a kind of suitable for sun
The racetrack bioreactor of light batch production, the bioreactor can effectively solve that cement pit floor space is excessive, open pond
Easily pollution, illumination damages serious, the excessively high technological deficiency of aquaculture cost using frond in insufficient, breeding process.
To achieve these goals, the present invention is adopted the following technical scheme that：

Water supplements below pipe distance bottom of pond 0.15m；Raceway pond thickness is homogeneous, is 3mm；Raceway pond cumulative volume is 20m3, it is total take up an area be
50m2, compared with existing open cement pit, present invention cleaning, environmental protection can effectively improve soil repeat usage, it is to avoid dirty
Dye soil；Described raceway pond, at the 0.3m high of pond, the outside of pond two is respectively provided with buckle, and buckle can open both sides raceway pond, work as training
Outside can be sealed with buckle when supporting algae.
Further, described racetrack bioreactor also has piece in two-sided runway cleaning device, including cleaning pond
With cleaning pond outer plate, the two is densely placed in inside and outside raceway pond, using the sucking action of opposite pole can make the inside it is a piece of with
The a piece of motion in outside, because the wall built-up of microalgae occurs in pond inner surface, so either take whether manually or automatically changing cleaning
It is all very convenient.
Further, described heat exchanger water treatment facilities provides water source, heat exchanger for racetrack bioreactor
Water treatment facilities provides initial water source by the initial fill Guan Weiqi positioned at raceway pond corner, then, is mended by injecting water
The 8-10 roots ascending pipe filled on pipe is for raceway pond provides supplementary water injection.
Further, described automation stream Ensure Liquid salt supplementary device is mended according to computer setting program by nutritive salt
The 8-10 roots ascending pipe filled on pipe is for raceway pond provides nutritive salt.
Further, described CO2Blowdown pipe sets an opening every 0.1m, and opening direction is obliquely, to prevent frond
Precipitation, makes frond be well mixed in nutrient solution, prevents pollution；CO2Throughput is 1-3%V：V, Reynolds number is 2 × 103-2×
105, to avoid medium pH value decline and microalgae cell because inflation shearing force is excessive and damaged and disclosure satisfy that microalgae carbon source
Supplement.
Further, the material of described culture apparatus main body is transparent acrylic PC materials；Closed acrylic PC materials
During material, can be prevented effectively from pollution of the culture environment to algae in incubation, and transparent material substantially increases culture pond
The illuminating surface product volume ratio of algae solution, improves the illumination utilization rate of reactor, the culture density of reactor is improve, so as to carry
High production rate；Compared with plastic foil Photoreactor, bearing strength is high, repeats and utilizes, and is more suitable for factorial praluction.
Further, described stainless steel stent 0.5-1m high, support lower section is provided with some movable wheels and its in dynamic dress
Put, device is saved land seizure area to greatest extent, it is to avoid land resource pollutes.
Further, secondary light source LED is red LED cold light lamp, blue led cold light lamp and White LED cold light lamp；Phase
More single artificial light source thermal source, can significantly economize on resources, it is to avoid the wasting of resources；And water temperature keeps most thermophilic needed for micro algae growth
Degree, illumination, under Ru Yin, rainy day poor weather and night without natural light when, can be in the rollable modeling of covering of pond body top
Material light transmission film uses secondary light source, promotes micro algae growth, shortens the microdisk electrode cycle.
Simple structure of the present invention, it is easy to operate, the illuminating surface product volume ratio of algae solution in culture pond is substantially increased, change
The illumination utilization rate of bioreactor has been apt to it, has improve the culture density of Race-way photobioreactor, has greatly improved production
