Description

High oxygen solubility ferment pot
The utility model relates to the fermentation equipment in a kind of biochemical engineering, especially to the improvement of single port aeration-agitation fermentor tank.
How to improve fermentation unit in the aerobic bacteria fermentative production, to obtain single jar of higher output, people constantly explore at the bacterial classification process aspect, simultaneously equipment have been proposed raising dissolved oxygen speed, reduce the requirement of power of agitator to reduce production costs.For a long time, traditional single port aeration-agitation fermentor tank inner member many-sided research and improvement have been carried out, attempt by reducing air flow, strengthen the purpose that power of agitator reaches increases dissolved oxygen in the fermented liquid, obtained certain effect, but effect is not ideal enough, the increase of shaft power, cause the increase of energy consumption, cost rises.Simultaneously, in the aerobic bacteria fermentative production,, improve tank pressure, can improve the dissolved oxygen in the fermented liquid, but tank pressure is too high according to Henry's law, the one, influence air flow quantity, the 2nd, rise significantly in the molten angle of carbonic acid gas, unfavorable to fermenting.The air feed of aeration-agitation fermentor tank is finished by air compressor, and air has obtained great energy in compression process.The resistance that wherein minimum part is used for overcoming in the airing system has been consumed.When entering fermentor tank, the kinetic energy that pressurized air had but is not fully utilized, and the waste of this part energy is huge; The main effect of aeration-agitation fermentor tank bottom blade is that the air that enters in the fermented liquid is cut apart small bubbles in small, broken bits, increases the gas-to-liquid contact area, and still, it is limited increasing dissolved oxygen coefficient under the certain situation of agitating vane circular frequency.Chinese patent 91226248.6 " a kind of gas-lift fermentation reactor " adopts the internal-circulation type structure, by the circulation of multistage minor cycle, makes the gas-liquid contact time lengthening, and oxygen dissolution is more abundant, but device is complicated, and energy consumption is still very high.
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, dissolved oxygen efficiency height, the High oxygen solubility ferment pot that energy consumption is low, running cost is low.
The utility model can be realized like this: High oxygen solubility ferment pot, comprise housing, stirring rake, inlet pipe, the bottom that it is characterized in that housing is provided with the jet gas liquid mixer that communicates with inlet pipe, and row's pipe of several jet gas liquid mixer evenly is set around the central shaft of housing.The jet gas liquid mixer communicates with inlet pipe, under the situation that does not change supply gas pressure, can improve flow velocity, reaches the purpose that increases dissolved oxygen.Fermented liquid is subjected to fiercely washing away of high velocity air in jet mixer inside, makes gas-liquid obtain abundant, close contact, and bubble and bacterial classification surface thickness of liquid film is reduced, and quickens the speed that dissolved oxygen and nutrition enter cell interior.Around the even row's pipe that is provided with of the central shaft of housing, will be through the fermented liquid behind the high velocity air thorough mixing with higher flow velocity, discharge from row's pipe mouth of pipe by same circumferential direction, make the fermented liquid of this layer form eddy current, its direction is consistent with the sense of rotation of agitating vane, can substitute stirring rake bottom blade, like this under the situation that does not increase power of agitator, make full use of the kinetic energy of air, the fermented liquid flow velocity is higher, turbulence is more severe, simultaneously several row's pipes than single port sparger gas-liquid mixed contact surface more disperse, bigger, this is more favourable to fermentative production.The radical of row's pipe can be considered according to factors such as the size of tank body and intake pressures, be generally 3~10.
In order to make the dissolved oxygen better effects if, each row's pipe all is provided with the jet gas liquid mixer and communicates with it.Gas-liquid is more disperseed like this, the less turbulence that the fermented liquid that row's pipe mouth of pipe is discharged forms is more severe, shorten the fermented liquid internal recycling cycle, eliminate fermented liquid dissolved oxygen dead angle, increase small bubbles polymerization difficulty, prolong air in the time of fermented liquid internal stops, thereby reach the purpose that improves air utilization ratio, reduces air feed.
The inclination angle of row's pipe can 0 °~55 °, this inclination angle is meant the direction of row's pipe mouth of pipe place's fermented liquid discharge and the angle of horizontal plane, reasonably the inclination angle can make less turbulence very remarkable, is generally 10 °~35 ° preferably, and too big or too little meeting makes the scope of fermented liquid turbulence be subjected to certain limitation.
Jet gas liquid mixer described in the utility model is the general aerating apparatus in environmental protection field, form by nozzle, air suction inlet, suction chamber, mixing tube, row's pipe, gas, liquid through nozzle and suction chamber carry out fierce doping in mixing tube, make air be ground into minimum bubble, enter row's pipe with the form of air water emulsion.
The utility model is simple in structure, and the dissolved oxygen effect is remarkable, and energy consumption is low, and running cost is low, will play positive pushing effect to aerobic fermentation production.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model vertical view.
Fig. 3 is a jet gas liquid mixer synoptic diagram of the present utility model.
Further specify the utility model below in conjunction with accompanying drawing.
Embodiment 1, a kind of fermentor tank, comprise housing (1), stirring rake (2), inlet pipe (3), be provided with jet gas liquid mixer (4) in the bottom of housing (1), jet gas liquid mixer (4) communicates with inlet pipe (3), the jet gas liquid mixer is common efflux aerator, and the central shaft that centers on housing (1) evenly is provided with several row's pipes (5) as 3 jet gas liquid mixer, and row's pipe (5) in horizontal direction, be that its inclination angle is zero, the mixture of gas and fermented liquid is discharged.
Embodiment 2, a kind of high dissolved oxygen fermentation reaction jar, comprise housing (1), stirring rake (2), inlet pipe (3), be provided with jet gas liquid mixer (4) communicates with inlet pipe (3) in the bottom of housing (1), central shaft around housing (1) evenly is provided with several as 10 row's pipes (5), and the inclination angle of each row's pipe (5) is 55 °.The bottom blade of the stirring rake in this fermentor tank can be removed, the turbulence that is caused by row's pipe of jet fluidized bed mixer substitutes the effect of stirring rake bottom blade, degree according to turbulence, the inclination angle can be set to 10 °~35 °, the inlet mouth (6) of jet gas liquid mixer (4) communicates with inlet pipe (3), fluid inlet (7) communicates with fermented liquid, by the effusive effect, gas that enters and fermented liquid are discharged by row's pipe (5) mouth of pipe of jet gas liquid mixer after carrying out in mixing tube (10) fully, mix closely through nozzle (8), suction chamber (9).Can increase the dissolved oxygen effect like this, energy consumption reduces simultaneously, and running cost is descended.
