A kind of small-sized fermentation tank exhaust gas processing device
Technical field
The utility model is related to biological fermentation field more particularly to a kind of small-sized fermentation tank exhaust gas processing devices.
Background technology
In the fermentation process of aerobic bacteria, with the process of fermentation, the gradual increase of cell concentration, to the demand of oxygen
Also gradually increase.In the process, total process of fermenting needs to ensure constant pressure inside the tank again, is then increasing the same of ventilatory capacity
When, exhaust emissions is also constantly to increase;And it is discharged in tail gas and contains a large amount of bacterium;If not in time by the work in tail gas
Bacterium inactivates, it is easy to lead to the pollution in fermentation room environmental or cause large-scale phage-infect.
However processing of the fermenting experiment room to fermentation tail gas now, usually all it is direct emission or equipped with thimerosal
Simple process in bottle, easily leads to that vent gas treatment is not thorough or processing capacity is insufficient in this way, and continues to be exhausted directly in environment.
Therefore, there is an urgent need for the new processing units to fermentation tail gas for this field.
Utility model content
The purpose of the utility model is to overcome this field it is existing to fermentation tank generate the halfway problem of vent gas treatment,
And then provide a kind of small-sized fermentation tank exhaust gas processing device.
A kind of small-sized fermentation tank exhaust gas processing device provided by the utility model, including exhaust system and multiple vent gas treatments
Unit;Each tail gas treating unit includes process container, offgas duct and exhaust pipe;The process container is equipped with sealing cover, institute
State sealing cover be equipped with for the offgas duct and the exhaust pipe by hole, tried equipped with vent gas treatment in the process container
Liquid;One end of the offgas duct connects fermentation tank tail gas floss hole, and the other end is inserted into the process container by the sealing cover,
And it is submerged into the vent gas treatment test solution;The process container, port are inserted into one end of the exhaust pipe by the sealing cover
On the liquid level of the vent gas treatment test solution, the other end of the exhaust pipe is connect with exhaust system;The exhaust system
It is connected with exhaust system.
Preferably, the other end of the exhaust pipe is connect by three-way connection with exhaust system.
Preferably, the process container is feed supplement bottle.
Preferably, the exhaust pipe is equipped with valve.
Preferably, the exhaust system is equipped with sewage draining exit, and the sewage draining exit is arranged for discharging liquid or solid waste.
Preferably, the exhaust system is tubular structure.
Preferably, the exhaust system is pvc pipe.
Preferably, the tail gas treating unit is 2-10, more preferably 4-6.
Preferably, the vent gas treatment test solution is disinfection solution.
Preferably, the disinfection solution is:Lye, ClO 2 solution, hydrogen peroxide solution, liquor natrii hypochloritis or
Liquor potassic permanganate.
Technique effect
When the exhaust gas processing device work of the fermentation tank of the utility model, fermentation tail gas is passed through from fermentation tank through offgas duct
In vent gas treatment test solution, treated, and tail gas enters exhaust system through exhaust pipe, then is discharged by air draft.In exhaust treatment system
Tail gas treating unit can simultaneously to multiple fermentation tanks generate tail gas handle.The tail of fermentation tank described in the utility model
Gas processing system is simple and practicable, at low cost, safe, has preferable application and promotion prospect.
The technique effect of the design of the utility model, concrete structure and generation is made furtherly below with reference to attached drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Wherein, 1 is feed supplement bottle, and 2 be offgas duct, and 3 be exhaust pipe, and 4 be valve, and 5 be three-way connection, and 6 be fermentation tank, and 7 are
Exhaust system, 8 be sewage draining exit, and 9 be exhaust system.
Specific implementation mode
Embodiment 1
As shown in Figure 1, the exhaust gas processing device of the fermentation tank of this example includes exhaust system 7 and four vent gas treatment lists
Member, each tail gas treating unit include feed supplement bottle 1, offgas duct 2 and exhaust pipe 3;Packed bilateral is set on the feed supplement bottle 1
Lid, feed supplement bottle 1 is interior to be equipped with vent gas treatment test solution;One end of the offgas duct 2 connects fermentation tank 6, and the other end passes through in bilateral lid
One of hole be inserted into feed supplement bottle 1, and immerse in vent gas treatment test solution, another hole of bilateral lid is inserted with exhaust pipe 3
One end, the port of exhaust pipe 3 is located on vent gas treatment test solution liquid level, is not contacted with vent gas treatment test solution;Exhaust pipe 3
The other end is connect by three-way connection 5 with exhaust system 7, and valve 4 is additionally provided on exhaust pipe 3;The exhaust system 7 is tubulose knot
Structure, and be connected with exhaust system 9.
The exhaust system 7 is equipped with sewage draining exit 8, and the sewage draining exit 8 is arranged for discharging liquid or solid waste.This reality
It applies in example, exhaust system 7 is tubular structure, for example is pvc pipe.
In the present embodiment, the vent gas treatment test solution is disinfection solution conventional in the art, such as:Lye, titanium dioxide
Solutions of chlorine, hydrogen peroxide solution, liquor natrii hypochloritis or liquor potassic permanganate.
When the exhaust gas processing device work of fermentation tank, fermentation tail gas is passed through vent gas treatment examination from fermentation tank 6 through offgas duct 2
In liquid, treated, and tail gas enters exhaust system 7 through exhaust pipe 3, then is discharged by exhaust system 9.When the tail of multiple fermentation tanks
When gas accesses same tail gas treating unit simultaneously, at the tail gas which can simultaneously generate multiple fermentation tanks
Reason.
The preferred embodiment of the utility model described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to the design of the utility model in domain
