Description

Combination type bioreactor

Technical field

This utility model relates to microdisk electrode technical equipment field, specifically, relating to a kind of combination Formula bioreactor.

Background technology

Microalgae can utilize luminous energy and CO₂The organic components such as synthetic protein, fat and carbohydrate, on ground The Carbon cycle of ball and energy circulation play a significant role.Some kinds of microalgae is rich in polyunsaturated fat The high level bioactive substance such as acid, active polysaccharide and natural pigment, therefore become food, feedstuff, fuel and The important materials source of medicine and other fields.

At present, in the world, Microalgae biotechnology quickly formed one huge complete Industrial chain, scale evaluation therein is important step.For cultivating microalgae, researcher invented multiple opening or Airtight reactor.Specific surface area is big, volumetric ratio big, be difficult to pollution, material because having for pipeline Photoreactor Exchange efficiency is high, be prone to the advantages such as technique amplification, and the biomass yield cultivating microalgae is higher, the most biological one-tenth The accumulation divided is also easier to control, thus the industrialization being widely used in microalgae is cultivated.

But, tubular reactor is expensive, and this external light and nutrient substance supply respect exist some drawbacks. On the one hand, in reactor, the exchange rate of the carbon dioxide and oxygen of frustule suffers from the limit of duct length System, long pipeline may cause micro algae growth the under-supply oxidation with oxygen excess enrichment of carbon dioxide occur Coerce；On the other hand, pipe radius would generally be improved for expansion scale, and this operation can be substantially reduced instead Answer the photopermeability in device, during causing micro algae growth, occur that light limits.

Additionally, generally use the mode of pumping to realize culture fluid turnover and the flowing in pipeline, cultivate liquid pump The amount of sending is big, energy consumption is high, and the mechanical shearing of water pump easily produces damage to frustule.By comparison, pillar is anti- Answering employing Airlift aeration device in device, on the one hand the bubble stream of rising enable culture fluid good mixing and make Frustule keeps well suspended, on the other hand enhances carbon dioxide dissolving transmission in culture fluid in bubble And the oxygen that in culture fluid, the photosynthetic growth of frustule produces is to the transmission of bubble, it is achieved thereby that mend carbon deoxygenation； But this pillar pipeline reactor yet suffers from some problems when being applied to microalgae mass cultivation, than As: the same cost of manufacture of traditional column reactor is expensive；Traditional column reactor needs to be passed through bigger stream The mixed gas of amount makes algae solution mix homogeneously.This had both caused the waste of gas, also made to cut suffered by frustule Shear force is excessive, causes frustule to be easily broken with adherent.Additionally, this also makes feeder needs higher Supply parameter (or more air feed equipment) produces required with satisfied high-volume column reactor.

In sum, it is necessary to design a kind of new device, said one or multiple problem are solved.

Utility model content

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, it is provided that a kind of use, cleaning side Just combination type bioreactor.This device can improve carbon dioxide supply, removes in culture fluid in time Molecular oxygen；Meanwhile, reduce the energy consumption of incubation, improve the gas distribution consistency degree in reactor, it is ensured that Frustule fully stirs；The length of adjustable reactor shaft carrys out regulation culture volume；Additionally cleaning reaction During device, reactor partially or fully disassembly, cleaning can be cleaned without dead angle.

In order to reach above-mentioned purpose, this utility model adopts the following technical scheme that

Combination type bioreactor, including reactor head, reactor shaft and reactor base；Described Reactor head removably connects with reactor shaft, and described reactor shaft and described reactor base also may be used Dismounting connects；Described reactor head, reactor shaft and reactor base are monolithically fabricated triplet pillar knot Structure；
