Description

A kind of stirring structure that anaerobic fermentation tank is novel

Technical field

The utility model relates to anaerobic fermentation tank technical field, specially a kind of stirring structure that anaerobic fermentation tank is novel.

Background technique

The whipped form of anaerobic fermentation tank is broadly divided into two kinds at present, and one kind is top stirring, and another kind is that side is stirred, this two Kind of whipped form is all haveed the shortcomings that different, and common drawback is exactly that biogas slurry surface is easily crusted.But the fermentation of anaerobic fermentation The critical performance parameters such as time, factor of created gase all have much relations with it, that is to say, that the entire engineering of anaerobic fermentation it is technologically advanced Degree is directly linked therewith, for this purpose, each engineering unit all solves problems trying every possible means.We by various experiments, Simulation test has investigated this novel stirring structure, solves the problems, such as that liquid level crusts in anaerobic fermentation tank, improves hair Ferment rate and factor of created gase.

Because domestic biogas industry (large size) is started to walk, late development speed is slow, more external backward 30 or 40 years of the same trade, especially Being is even more to fall behind in terms of the stirring of large fermentation tank.Currently, blender used in the domestic preferable biogas project of operation is mostly Import, producer only few in number copies similar blender according to state's external structure, but structure type is all nothing more than two Kind, top stirring or side stirring.Its performance is not said how, but scarce with regard to not solving itself to be individually present from the point of view of service condition Point.It is exactly to form one layer of hard shell (film) in biogas slurry face that wherein they have one big problem jointly, influences the fermentation of entire engineering Rate and factor of created gase.

1, hard shell (film) Forming Mechanism:

Volatilization discharge is largely carried with the output of biogas in fermentation process biogas slurry surface moisture, causes surface due to dehydration One layer of hard shell (dura mater) is formed, this layer of shell of extension at any time becomes thick and hard, thus influence to run out of in the slave biogas slurry of biogas, into And entire anaerobic fermentation rate is reduced, as the material not fermented thoroughly discharge is caused to waste by continuous charging discharging, make entire The TS factor of created gase of engineering is low (quality of TS expression dry matter).This phenomenon shows especially prominent, straw in stalk anaerobic fermentation Stalk water suction after specific gravity it is still light compared with biogas slurry, just into material do not pass through sufficient fermentative degradation, still swim on liquid level.Surface Stalk contained humidity is even more to generate with biogas and be discharged therewith, and causing the stalk on surface to be floated on liquid level by wet exsiccation cannot Fermentation, it is cumulative to form so-called hard shell (film).

2, the major defect of two kinds of whipped forms:

Top stirring, which can be used only in, resists stubbornly on tank, is used primarily on the fermentor resisted stubbornly, and structure type is to pass through speed reducer band Dynamic blade stirs fermentation liquid.Its structure is multi-layer oar blade stirring, that is, spaced apart on vertical stirring axle is set One group of blade (two leaves or leafy) is set, the fermented liquid generation made by the rotation of blade is stirred.But this stirring is produced In raw a certain range fluid levels flow, about should above and below blade between 400----500mm, because material viscosity and its His property and it is different.Especially top layer blade stirring layer because liquid level it is remote away from blade, liquid level with agitating shaft rotate but rapids cannot be formed Stream (does not seethe) up and down.

Mainly several inclined agitating devices are arranged in lower part in the fermenter for side stirring, (similar using the turbine of end The turbine propulsion of ship) rotation generates thrust and biogas slurry flowed along tank skin, and cause liquid to form eddy flow, although along axial stream Body forms biggish turbulent flow, but its remoter mixing effect of distance axis is poorer, and liquid level above substantially spins and can not form up and down Seethe so that top newly into unleavened cannot adequately be mixed in time with biogas slurry.It is this be stirred it is darker than below deep-sea Stream is sprung up and sea is calm.

In conclusion anaerobic fermentation process broken shell is at urgent need to solve the problem, it is new to develop anaerobic fermentation for we thus Type stirring structure solves this problem.
