When the emulsifying-type aerobic fermentation tank of the utility model uses; By feed pump substratum feed liquid in the dosing chamber is sent in the jar through opening for feed 14; After sterilization, ventilation cooling (steam, air must get into gas-liquid injection emulsifier unit 2), bacterial classification is cultivated in strain nutrition mouth 16 immigration jars.0.07 the aseptic compressed air of～0.35Mpa pressure is sent into through tank body inlet pipe 4 and is respectively welded bend pipe 22 on gas-liquid injection emulsifier unit 2 endless tubes 25, and gets into respectively and respectively enclose the gas-liquid emulsor 24,27,28 of gas-liquid emulsor group 29,30,31.When air quantity is V p, pressure is P pPressurized air from gas-liquid emulsor nozzle 32 (W at a high speed 1) ejection, when the pressurized air static energy is transformed into the speed ability, be γ with severe 1, pressure is P 1Fermented liquid V LSuck and together get into the diffuser tube 35 of gas-liquid emulsor, in the collapsible tube of diffuser tube 35, trunnion, gas, liquid two-phase are expanded to fierce mixing concussion and are produced pressure foamization and aerodynamic force foamization by preliminary mixing, and its foam result makes the entering air V pWith the fermented liquid V that is inhaled into LImpact is dispersed into a large amount of small grain crowds, causes the great and surperficial emulsification mass transfer interface of bringing in constant renewal between gas, liquid, and airborne oxygen is fully used; Mass transfer velocity, dissolved oxygen coefficient improve; In the convergent divergent channel of diffuser tube 35, along with the increase of expansion section, gas-liquid mixture flow velocity (W 2) decline, static energy is able to progressively recover, by means of the poor (P of static pressure of gas-liquid emulsor diffuser tube entry and exit places gas-liquid mixture 1>P 2) and the poor (γ of severe 1>γ 2); The radially loopful stream motion that the gas-liquid mixed deposits yields is gone round and begun again; Seeing that gas-liquid emulsor 24,27,28 diffuser tubes 35 outlets of every circle gas-liquid emulsor group 29,30,31 are all on the tangent to periphery direction of same xsect; Make gas-liquid mixed stream spirrillum swirling motion, increased the movement locus of micro-bubble in fermented liquid, increased the duration of contact of oxygen and mycelia.Screwing out pressure from 2 sprays of gas-liquid injection emulsifier unit is P 2, severe is γ 2Gas-liquid mixture (V p+ V L) all get into gas-liquid mixed circulating device 3 bottom first step gas liquid mixer 36 collapsible tubes, under the spray effect of revolving of gas-liquid mixed stream, by means of the poor (P of static pressure of place, gas liquid mixer at different levels 36,38,40 entry and exit gas-liquid mixture 3>P 4>P 5>P 6), the poor (γ of severe 3>γ 4>γ 5>γ 6), velocity contrast (W 3>W 4>W 5) and air self-suction sprays, and tail pipe 41 tangent lines get into speed ability and the pressure ability that second stage gas liquid mixer 38 gas-liquid mixed flow, three grades of injection gas-liquid mixtures (fermented liquid) V in the emulsification supercharging device 11 3, V 4, V 5, realizing that gas-liquid mixture axially mixes, the swirling motion of internal recycle, increase gas, liquid two alternate mixture strengties contact opportunity with oxygen with mycelia, make the oxygen in the gas phase obtain recycled for multiple times.The aggravation of stirring along with the cellular spherical micro-bubble crowd's of full bed rising, coalescence and gas-liquid emulsus stream; Gas, liquid mixture are behind steady liquid froth breaking sieve plate 12; Bubble is overflowed from cultivating liquid level, and forms the gas-phase space of 0.015～0.05Mpa pressure emission gases at tank body 6 tops.Because airborne oxygen is the gas that is insoluble in water; Solubleness is not high in fermented liquid; Its utilization ratio is very low; Therefore in the gas-phase space of emission gases, still contain a large amount of oxygen parts, in order to utilize the oxygen in the emission gases again, to improve mass transfer velocity, dissolved oxygen coefficient and unit output; By the fermentation liquid pump through fermented liquid outlet pipe 21 tank body 6 inner bottom part fermented liquids are sucked and send into tank body 6 bottom fermented liquid inlet pipes 19, air self-suction sprays each branch pipe welded directly to the run pipe 44 on liquid-inlet pipe 46, endless tube 45 and the endless tube 45 in the emulsification supercharging device 11, sends into liquid gas emulsification supercharging blower 42,47,48 more respectively.When flow is V L, pressure is P L(0.35～0.6Mpa) fermented liquid is from liquid gas emulsification supercharging blower nozzle 49 high speed (W 6) ejection, when the static energy of fermented liquid changes the speed ability into, be P with pressure in the tank body 6 top gas-phase spaces p(0.015～0.05Mpa) and contain the emission gases V of a large amount of oxygen pSuck voluntarily, through air intake pipe 43, tangent line gets into the mixing section 51 of liquid gas emulsification supercharging blower, under the continuous injection effect of fermented liquid, with the emission gases V that sucks pThe diffuser tube 52 of bringing liquid gas emulsification supercharging blower into carries out liquid, gas two alternate quality and transmission ofenergy conversion; Supervene the intensive friction, vibrate, break and foamization; Make fermented liquid and suck gas and become a large amount of small grain crowds, form the contact interface that height turbulence between liquid, gas and surface are brought in constant renewal in, increase the gas-to-liquid contact specific surface area by impact grinding once more; Realize the emulsification mass transfer; Along with the growth of diffuser tube 52 length of throat and dwindling of convergent divergent channel flare angle, gas-liquid mixed concussion and emulsification are prolonged duration of contact, and make liquid gas emulsification outlet pressure of the booster P L.PIncrease (P L.P>P P), fermented liquid and the enterprising flow characteristics that goes out down of suction gas all help improving the transmission of oxygen in fermented liquid in addition.Thereafter along with the increase gradually of expanding section, the flow velocity W of gas-liquid mixture 7Progressively descend; Static energy is able to progressively recover; Have certain speed can with pressure can flow through second stage gas liquid mixer 38 trunnions of tail pipe 41 tangent lines entering gas-liquid mixed circulating device 3 of gas-liquid emulsus carry out cyclic motion repeatedly; Final bubble is overflowed and is cultivated liquid level, discharges from venting port 17 through gas-phase space.Fermented liquid, is pumped to extraction workshop section through fermented liquid outlet pipe 21 usefulness fermented liquids and obtains through refining product after reaching the desired productive capacity of zymotechnique through the cultivation of certain hour.
The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model all falls in the protection domain of the utility model any simple modification, equivalent variations and modification that above embodiment did.
