Abstract
The invention is to ventilate compressed air into fermentation tank through stirring axial core, and open cell on blade or ventilate air to short pipe cooperated with position and way of paddle, the air outlet is near to paddle to reach maximum diintegration degree, and mix instantly with liquid. The invention overcomes the shortcomings of relative long route of air in other ventilating way, direct rising of bubble to liquid upper side without passing through stirring area, and low avalability rate of air (oxygen), and reduces energy consumption, such as time, stirring power and ventilating amount. The counteracting force of air injector boosts the sitirring and favourable for increasing stirring efficiency and saving energy.
Description
Technical field
Fermentation equipment in chemical industry, medicine, biology, food, the light industry.
Background technology
21st century is the century based on biotechnology, and fermentation is the basis of biotechnology industry.The biological respinse macrokinetics is the basis of optimizing fermentation, and bio-reactor is the outside atmosphere of fermenting process, and it influences the efficient and the optimization of fermenting process equally.
The aeration-agitation fermentation equipment is used widely in the fermentation equipment, but ventilating mode in any case, and air is all served as reasons and outside ventilated by sparger etc. through pipeline access arrangement inside separately.The present invention is fully smashed gas by changing ventilating mode exactly, makes the gas-liquid thorough mixing, reaches to improve dissolved oxygen rate, reduction energy consumption, thereby improves the equipment of fermentative production level.
Summary of the invention
The present invention is that the stir shaft core that pressurized air passes through fermentor tank feeds device interior, cooperates the position and the form of stirring arm, rationally axle radially or perforate on the stirring blade (or short tube) import air.We can obtain to draw a conclusion thus: because the relative position of pneumatic outlet and stirring arm is very near, make air obtain farthest smashing, and fully quick and liquid mixing.Overcome other ventilating modes (gas is through long relatively path, and part is not passed through stirring area) bubble and directly be raised to liquid level upper end, the low shortcoming of oxygen (air) utilization ratio.Thereby fermenting process be optimized and improved efficient, reached following effect:
1, since air smash and fully improved dissolved oxygen rate, thereby improved the fermentative production level, promptly improve production concentration (fermentation unit), substrate conversion efficiency and production intensity (fermentation period).
2, from last advantage as can be known when the identical production level, but save energy, reduce production costs.
3, nozzle placement is in the relative sense of rotation of the paddle back lower place, and promptly jet direction is opposite with the stirring sense of rotation.Air has played the effect that boosting stirs like this, thereby can reduce power of agitator relatively, reaches the purpose of save energy.
4, because the agitator centrifugation makes the nozzle place produce negative pressure, help the save compressed air power source like this.
Description of drawings
Figure is the bioreactor construction synoptic diagram.
Embodiment
Fermentor tank adopts universal machine stirred fermentor tank structure, only is described stirring blow and vent system.
This equipment adopts the setting product of motor 1 side and speed reduction unit 2 direct connection forms, the speed reduction unit design selection be about two ends through type output shaft form.Speed reduction unit 2 is installed on the upper end of fermentor tank tank body 4 by support 3.
After pressurized air imports hollow stir shaft, be ejected into (agitator need not adopt the form of center tep reel, and bubble can not be raised to liquid level along the stir shaft short circuit) in the bio-reactor via hollow stirring blade 9.The same employing of paddle is hollow makes through punching press or welding, can be according to kind design paddle form and definite paddle quantity of different fermentations product.At paddle lower edge non-uniform Distribution perforate welding tip 10, nozzle is to oblique arranged beneath and opposite with the stirring sense of rotation.The relative nozzle bore of far-end strengthens, and promptly strengthens air flow quantity.Can guarantee as far as possible that like this air is evenly distributed in liquid.Air is derived the back and can fully be disperseed under action of centrifugal force in addition, and is fully smashed through very short distance under the effect of next paddle and mixed, has avoided bubble to take place without smashing the situation that rises to liquid level.Improved the utilization ratio of air greatly, dissolved oxygen rate improves in the liquid thereby make.Simultaneously the reactive force of air nozzle plays the effect of boosting to stirring, helps the raising of stirring efficiency, the saving of the energy.The centrifugal force that agitator produces makes the nozzle place produce negative pressure, helps the saving in compressed-air power source.
Other block construction of this equipment is selected for use according to kind, and existing forming technique is not described.
The present invention can only be described with structure sign, functional character in experiment.Because of the factor of influence in the fermentative production experiment is very many, the existing scientific and technological ability of some parameter can't all realize Comparative and Quantitative Analysis.General influence factor has: hardware condition of the control of kind, seed quality, the substratum similarities and differences, disinfecting action, each index of production process, operator's level, production or the like, multinomial dynamic factor make the data contrast be difficult for realizing.
