Description
The utility model relates to a kind of energy-conservation fermentor tank, belongs to technical field of chemical, is particularly useful for aerobic fermentation.
In biotechnology, the fermenting process of aerobic microorganism mostly is to adopt to feed the pressurized air bubbling and mechanical stirring is set to realize oxygen supply.And the fermentor tank that widely adopts generally all adopts single port air inlet or the air inlet of annular spread pipe, cooperates with lower floor's paddle and smashes bubble, increases the gas-to-liquid contact area, realizes gas-liquid mass transfer.This type of fermentor tank dissolved oxygen effect is general, and the electric energy that air compressor and mixer drive consumed is bigger.Be that generally to be used for churned mechanically installed power be 2-2.4kw/m to example with the penicillin fermentation
3Fermented liquid is about 1-1.3m and feed compressed air require
3/ m
3The fermented liquid per minute is amounted to air compressor machine power and is roughly 3.5-4.6kw/m
3Fermented liquid stirs and ventilation power consumption sum is 5.5-7kw/m
3Fermented liquid accounts for the total cost significant proportion.So how to reduce power consumption, reduce running cost is the fermentation important topic that the insider studied always.The U.S. once adopted six flat-blade turbines to strengthen power of agitator to 3.5kw/m
3Fermented liquid, the air consumption is reduced to 0.3-0.5m simultaneously
3/ m
3The fermented liquid per minute is obtained same ferment effect, though total power has descended, has brought the increase of fermentor tank thermal load simultaneously, does not obtain promoting.Chinese patent 97236557 has related to a kind of High oxygen solubility ferment pot, utilize compressed-air actuated kinetic energy, adopt aerating apparatus commonly used in the environmental protection as gas liquid mixer, receive respectively in some branches of air line, improve dissolved oxygen by the turbulence of gas-liquid in mixing tank, each mixer outlet can be along the peripheral jet of same circumference to substitute lower floor's stirring rake, under the situation that does not improve the mechanical stirring power consumption simultaneously, reduce the air consumption, can play certain effect.Its shortcoming is as not removing lower floor's paddle, air input reduces and will cause churned mechanically power consumption to rise, and after lower floor's stirring is removed, it mixes and smashes the bubble defunctionalization, and can rise rapidly because of buoyancy from the micro-bubble of the oxygen enrichment fermented liquid of mixing tank ejection, so leaning against in the process by jet mixer substantially entirely, the fermented liquid dissolved oxygen of fermentor tank bottom obtains.And, just determined that the gas-liquid mass transfer of fermented liquid of fermentor tank bottom is low than middle and upper part efficient because of the limitation of air inlet amount and jet mixer quantity, and inhomogeneous, actual test proves that also the fermentor tank top and the bottom dissolved oxygen situation of this kind structure differs bigger.Above-mentioned in addition High oxygen solubility ferment pot all is that pressurized air passes the fermentation liquid layer after pot bottom enters the same with general fermentor tank for utilizing on the mode of air, is discharged by vapor pipe from the air that the fermented liquid liquid level is overflowed.Because of the solubleness of oxygen in water very little, pressurized air rises at the bottom of the jar the process more than the fermentation liquid level has only minimum part of oxygen to be utilized, with the penicillin fermentation is example, fermenting after testing, oxygen content has only 1% of air capacity to be utilized in the above air of liquid level, rise to the above residual air of liquid level and still have utility value, recycling then can reduce the consumption of fresh air by the utilization ratio that improves oxygen in the air at the bottom of it if can being caused jar.
The purpose of this utility model is to solve the low and uneven situation of fermentor tank bottom gas-liquid mass transfer efficient; Effectively utilize the compressed-air actuated problem in liquid level top.
The utility model is achieved by the following scheme: this energy-conservation fermentor tank, basic structure comprises tank body, mechanical stirring device and multistage jet flow mixing device, multistage jet flow mixing device comprises that tank base is provided with the air-distributor that links to each other with compressed air inlet pipe, uniform 3-8 air nozzle on sparger, behind each nozzle, all the one-level jet mixer is installed, coaxial installation secondary jets mixing tank or multistage jet mixer behind the one-level jet mixer along its injection direction.
Described energy-conservation fermentor tank is provided with uniform circulation air suction pipe and communicates with corresponding jet mixer, the air suction pipe fermentor tank liquid level top that is arranged at suitable for reading.
The catchment port of the secondary jets mixing tank of described energy-conservation fermentor tank can link to each other with the outlet of one-level jet mixer and constitute closed induction chamber, and induction chamber is connected with air suction pipe.
The catchment port of the secondary jets mixing tank of described energy-conservation fermentor tank does not link to each other with the outlet of one-level jet mixer, the uncovered fermented liquid that directly places.
Install hybrid element additional in the diffusive mixing chamber of the last step jet mixer of described energy-conservation fermentor tank.
The axis of every group of jet mixer of described energy-conservation fermentor tank and horizontal direction angle are the 0-35 degree.
The axis of every group of jet mixer of described energy-conservation fermentor tank in the horizontal direction projection and this projection plane on the jet mixer angle that is exported to jar center radius be the 0-90 degree.
The multistage jet flow mixing device of described energy-conservation fermentor tank can be installed one or more layers in fermentor tank.
The utility model has the advantages that from the above air of liquid level is recycled and increase fermented liquid strengthen jar by the cycle index of mixing tank in two angles of tank body bottom dissolved oxygen of fermentation liquid especially, be implemented in the best dissolved oxygen effect of acquisition under the minimum air consumption.
Further specify embodiment of the present utility model (is example with the secondary jets mixing tank) below in conjunction with accompanying drawing:
