Description
Technical field
The utility model belongs to microbial fermentation apparatus field, and in particular to a kind of circulation defoaming system.
Background technique
Biosurfactant itself is a kind of foaming agent, can be generated along with stirring, oxygenation during the fermentation a large amount of
Foam, in contrast, in fermentation process foam generate rate, total amount all be significantly larger than other conventional products.In fermentor
A large amount of foam reduces the bioavailability of substrate and the mass-transfer efficiency of oxygen, destroys the growing environment of microorganism, is unfavorable for
Thalli growth reduces the utilization efficiency of bioreactor, and it is poor to eventually lead to biosurfactant low output, production efficiency.
So far, it adds chemical defoaming agent and mechanical device brokenly bubble is most common two kinds of debubbling methods, but all there is certain lack
It falls into, there is biggish limitation especially in biosurfactant production process.During the fermentation, the addition meeting of defoaming agent
The increase of fermentation broth viscosity is caused, the economy of production process is reduced and is unfavorable for the downstream separation of product；More crucially
Biosurfactant itself has frothing capacity, and the quality of product can be seriously affected using defoaming agent；And mechanical defoaming is usual
Extra consumption higher-energy is needed, and studies the defoaming effect for confirming the high blistering active material similar for biosurfactant
Fruit is also unobvious.In conclusion a large amount of bubble problems do not solve well always at present in the fermentation of biosurfactant
Certainly, foam control problem is always the bottleneck for limiting its large-scale production；Therefore, it develops one kind and is applicable to Bio-surface active
Agent fermentation, the device of efficient foam control will be the important breakthrough mouth for promoting its large-scale production.
Summary of the invention
It is of the existing technology to solve the technical problem to be solved by the present invention is to provide a kind of circulation defoaming system
The problems such as energy consumption is excessively high, ineffective.
In order to solve the above technical problems, The technical solution adopted by the invention is as follows:
A kind of circulation defoaming system, it includes fermentor, foam collecting tank and foam liquefaction pipe；Wherein, fermentor, foam
Collecting tank and foam liquefaction pipe are sequentially connected to form closed loop by pipeline.
Wherein, fermentor gas outlet is equipped at the top of fermentor.
Wherein, it is equipped with the foam being sequentially connected inside foam collecting tank and enters pipe and foam refinement pipe.
Wherein, fermentor gas outlet is connected with the feed inlet that foam enters pipe.
Wherein, gas outlet is equipped at the top of foam collecting tank.
Wherein, foam collects pot bottom and is connected with the feed inlet of foam liquefaction pipe by pipeline；Wherein, along object on the pipeline
Direction of flow is successively arranged the first peristaltic pump and the first valve.
Wherein, the discharge port of foam collecting tank is connected with bottom in fermentor by pipeline；Wherein, edge on the pipeline
Flow of Goods and Materials direction is successively arranged the second valve and the second peristaltic pump.
Wherein, foam liquefaction pipe is equipped with foam probe, piston and control circuit；Wherein, control circuit is visited according to foam
The information of head feedback controls the opening and closing of the first valve and the second valve and the work of piston.
The working method of the utility model is as follows: the foam generated in fermentor is discharged by fermentor gas outlet, through foam
Enter in foam collecting tank into pipe, and is refined as micro-bubble through foam refinement pipe or is directly refined as fermentation liquid；Small gas
Bubble and fermentation liquid are entered in foam liquefaction pipe by peristaltic pump through pipeline；To micro-bubble and fermentation liquid full of foam liquefaction pipe
Afterwards, foam probe is triggered, the first valve is closed by control circuit, and open piston and twitch outward, so that in foam liquefaction pipe
Pressure reduces into negative pressure state, so that foam is ruptured because of internal and external pressure difference, realizes the liquefaction of micro-bubble；It is complete to micro-bubble
After portion is liquefied as fermentation liquid, the second valve is opened, fermentation liquid is pumped via pipes by peristaltic pump and continues to ferment in fermentor.
The utility model has the advantages that
Compared with prior art, the utility model structure is simple, can be automatically controled and carries out circulation defoaming fermentation, can be according to hair
Ferment different times blistering degree difference automatically adjusts defoaming effectiveness, efficiently solves the bubble in biosurfactant production process
Foam problem reduces thallus and product in fermentation process and is lost, and do not need addition defoaming agent in fermentation process, is conducive to product and exists
Line separation, is suitable for large-scale fermenting and producing, is a kind of practical, efficient, stable novel device.
