Description
Technical field
The present invention relates to the field that manufactures and designs of bioreactor agitating device, refering in particular to compressed air is the jet current atomizing mixer for bioreactor of the main energy sources novel high-efficiency and energy-saving that atomizes, mix and circulate.
Background technology
Bioreactor has mechanical agitation type and gas-lifting type two big classes at present.Patent CN200420054260.9 " the efficient paddle of the formula of backflowing " provides mechanical stirring device, its complex structure energy consumption height, sterilization difficulty; Patent 200420081413.9 " the outer circulation airlift bioreactor of band flow mixing device ", US6174720 " Modified bioreactor " (improved bioreactor), JP7177873 " Bioreactor " (bioreactor) utilizes strength to stir, structure of reactor is simple, there is not mechanical stirring system, compressed air is its single energy, energy consumption is lower, sterilization is simpler, and the subject matter of existence is that the ratio of height to diameter of reactor is bigger, brings supply gas pressure big, operating difficulties, problems such as dead angle appear in the gas-liquid mixed weak effect in the reactor, directly influence it and apply.Therefore, be badly in need of novel agitating device---the jet current atomizing mixer for bioreactor of a kind of energy-efficient, no flow dead of exploitation.
Summary of the invention
Shortcoming and deficiency in order to overcome mechanical agitation type and airlift bioreactor the purpose of this invention is to provide a kind of novel air and liquid mixer, are that the bioreactor interior flow field stirs, and improve mixing efficiency.Realize that technical scheme of the present invention is:
Jet atomization mixed biological reaction device comprises: reducer pipe, fixed head, jet atomization nozzle, compressed air ingress pipe, it is characterized in that reducer pipe is through particular design, be followed successively by diffusion chamber, hybrid chamber and jet atomization chamber from top to bottom, offer a plurality of liquid reactants suction inlets at hybrid chamber and junction, jet atomization chamber, circumferentially evenly distribute, the hole axial line and the reducer pipe axial line angle of cut are 45～90 °.Fixed head is provided with a plurality of liquid reactants suction inlets.Reducer pipe and fixed head, fixed head and jet atomization upper end of nozzle are used thread connection respectively, and the jet atomization jet expansion gos deep into reducer pipe, and jet atomization nozzle lower end links to each other with the compressed air ingress pipe.
Its operation principle is that Compressed Gas forms high velocity air through the jet atomization nozzle, form negative pressuren zone near the jet expansion, liquid is sucked the hybrid chamber of reducer pipe by the liquid reactants suction inlet, mix fully, improve mixing uniformity, strengthen two alternate heat and mass and courses of reaction, the atomizing of restive open type and mixed process are become in the jet current atomizing mixer of well-designed arrangement and control carry out, last gas-liquid mixture sprays from spout through diffusion chamber.Simultaneously,, enter the jet atomization chamber from fixed head liquid reactants suction inlet and participate in mixed process, avoided the appearance of flow dead because the strong swabbing action of high velocity air will drive the bottom liquid reagent flow.The jet current atomizing mixer of configuration varying number, its installation site of optimal design, angle can make the inner stirring of bioreactor fully, improve the mixed effect of whole interior flow field.
Advantage of the present invention is:
Jet current atomizing mixer utilizes the swabbing action of high velocity air, sucks liquid reactants automatically, can realize the stirring of a plurality of angles, avoids flow dead, and simple in structure, convenient operation and control.It can accelerate effectively inside reactor reaction speed, cut down the consumption of energy, be applicable to various retort shapes.It had both overcome mechanical stir-reactor complex structure and the high shortcoming of energy consumption, eliminated the problem that the airlift reactor ratio of height to diameter is big, inconvenience and flow blind angle are controlled in operation again, be convenient to actual conditions design new reactor, can undergo technological transformation to old reactor again according to gas-liquid.
