With flange 24.The spacing and the outer ring ejector group 7 of two circle ejector groups 7,8 equate with the spacing of tank body 10 inwalls, the ejector 21,25 of every circle ejector group 7,8 is along garden week uniform distribution, its outlet is all on all tangent lines in the garden of same cross section, ejector 21,25 is-10 °～30 ° with the angle of horizontal plane.
With reference to Fig. 3, endless tube 2 is arranged on tank body 10 inside (also can be arranged on the outside of tank body 10), endless tube 2 and three support angle steel 27 usefulness U type nuts 26 are connected and fixed, it is fixing with the welding of tank body 10 bottoms to support angle steel 27, and two circle ejector groups 4,5 are arranged on the endless tube 2, outer ring ejector group 4 has eight ejectors 28, inner ring ejector group 5 has four ejectors 31, and the branch pipe welded directly to the run pipe 29 usefulness flanges 30 on ejector 28,31 and the endless tube 2 are connected and fixed.The spacing and the outer ring ejector group 4 of two circle ejector groups 4,5 equate preferably that with the spacing of tank body 10 inwalls the ejector 28,31 of every circle ejector group 4,5 is along garden week uniform distribution, and its outlet is all on all tangent lines in the garden of same cross section.Ejector 28,31 is preferably 20 °～70 ° with the angle of horizontal plane, and two concentric garden ejectors 1 are set below endless tube 2, and the branch pipe welded directly to the run pipe 29 usefulness flanges 30 on ejector 1 and the endless tube 2 are connected and fixed, and ejector 1 is-5 °～5 ° with the angle of horizontal plane.
With reference to Fig. 4, ejector is by nozzle 32, web plate 33 and diffuser tube 34 constitute, and both separate nozzle 32 and diffuser tube 34, web plate 33 is formed by ring flange and gusset assembly welding, 34 welding of web plate 33 gussets and diffuser tube, nozzle 32 inserts in web plates 33 ring flanges, the flange 24 that web plate 33 ring flanges and arm 23,29 have, 30(are referring to Fig. 2, Fig. 3) be connected with nut.And diffuser tube 34 has collapsible tube, trunnion and diffuser tube, ejector diffuser tube 34 throats are 6～25: 1 with the cross-sectional area ratio of nozzle 32 throats, the angle of throat of nozzle 32 is 10 °～30 °, and the convergent divergent channel flare angle of diffuser tube 34 is 5 °～15 °, and its collapsible tube angle of throat is 20 °～90 °.
When feed pump feed liquid is sent into jet-type aerobic leavening tank ， And through material liquid entrance pipe 3 and adds water and be mixed with solvent or diluent, through sterilization, move into bacterial classification after, just open air intlet and cut down, by inlet pipe 18 with 0.7～3kgf/cm
2The aseptic compressed air of pressure is sent into the endless tube 2 of third stage jet mixer stirring device 19, enter the endless tube 36 of second stage jet mixer stirring device 16 through pipe connecting 17, enter the endless tube 6 of first step jet whipping appts 14 again through pipe connecting 15, thereafter the branch pipe welded directly to the run pipe on endless tube 2,36,6 enters the ejector 28,31,35,39,21,25 of each ejector group 4,5,37,38,7,8 and the ejector 1 of endless tube 2 belows respectively again.Nozzle 32 And that enter ejector when pressurized air (general spouting velocity is 90～250 meter per seconds) when nozzle 32 sprays at a high speed, this moment, compressed-air actuated static energy changed the speed energy into, made the pressure of diffuser tube 34 ingress be reduced to P
1, be r with severe
1Nutrient solution Xi Ru And and the air diffuser tube 34 that together enters ejector, throat at diffuser tube 34, gas, liquid two-phase are by preliminary mixing, power foamization and pressure foamization through gas reach fierce mixing concussion, make a certain amount of nutrient solution be become a large amount of small grain groups by vibrant pulverization, cause the surface in contact of but bringing in constant renewal in bigger between gas, liquid with air.Enter the convergent divergent channel of diffuser tube 34 when gas, liquid mixture after, along with the continuous increase of expansion section, bubble diameter also increases thereupon, and flow velocity reduces, and static energy is recovered, the static pressure P when diffuser tube 34 exits
2Pressure P greater than the ingress
1, this moment exit gas, liquid mixture severe r
2Will be less than the severe r of ingress
1The time, go out by means of ejector diffuser tube 34, the pressure difference and the severe of ingress are poor, make gas, the liquid biphasic mixture produces the motion of loopful stream, simultaneously because every circle ejector group 4,5,37,38,7,8 ejector 28,31,35,39,21,25 diffuser tube 34 outlets are all on all tangential directions in the garden of same cross section, make gas, the liquid two-phase produces spiral motion, to increase the residence time of bubble in nutrient solution, at this moment the part bubble is utilized by circulation, most of bubble rises along with the growth of time, in uphill process, because running foul of each other between the bubble, merge bubble diameter is increased, when bubble rose to certain altitude, the part bubble was sucked and pulverizes with further raising dissolved oxygen coefficient and enhancing gas by the ejector of the jet mixer stirring device of upper level, the degree of mixing of liquid two-phase.Last bubble is overflowed from cultivating liquid level, and air is with 0.15～1kgf/cm
2Pressure is discharged from venting port 11, and nutrient solution is through the cultivation of certain hour, after reaching the desired productive capacity of zymotechnique, through material liquid entrance pipe 3, with 1.5～3kgf/cm
2Pressurized air force feed to recycle section is obtained through refining product.
