Description
Technical field
The present invention relates to a kind of device for solid waste being carried out anaerobic fermentation process, belonging to anaerobic fermentation technology
Field.
Background technology
Anaerobic fermentation is one of effective way processing solid waste, and garbage is under anaerobic by microorganism
Metabolic activity and stabilized.Anaerobic fermentation is generally carried out in anaerobic fermentation tank, and anaerobic fermentation tank is that the growth of microorganism carries
For excellent condition, meet growth and the breeding of microorganism.In anaerobic fermentation tank, these biological performance its catalysis or metabolism
Function.Owing to can not there be dissolved oxygen, so need not stirring at a high speed in anaerobic fermentation tank, even if stirring the most only plays the work of mixing
With.Also can be passed through nitrogen etc. in anaerobic fermentation tank, but operating cost can be improved.
Anaerobic fermentation tank is not suitable for viscosity compared with big or that solids content is big occasion, because so solid material is at fermentation liquid
Interior skewness, mass transfer effect is the best.To this end, be also equipped with agitating device in some anaerobic fermentation equipments.
Chinese patent literature CN104893958A discloses one " organic waste high-temperature dry-type anaerobic ferment devices ", including
Hydrolysis acidification case and horizontal anaerobic fermentation tank, be provided with auger propeller in anaerobic fermentation tank.But this auger
Angle of rake effect is to advance material by anaerobic fermentation tank feed end to drainage conduit, it is achieved the intermittent feeding of installation for fermenting, continuously
Work and automatic discharge, complete a fermentation period, and material is simply stirred in progradation, and stirring only plays the work of mixing
With, mass transfer is had little to no effect.
A kind of " dry type anaerobic fermentation system " disclosed in CN105647793A, including the feed arrangement being sequentially connected with, anaerobism
Installation for fermenting and drawing mechanism, anaerobic ferment devices includes anaerobic fermentation tank and Monitoring and Controlling mechanism, sets inside anaerobic fermentation tank
Agitating device, agitating device is had to include the many shafts being arranged side by side from fermentation tank charging aperture to discharging opening successively and oar thereof
Leaf, agitating device realizes the stirring successively that many shafts move in circles under the control of Monitoring and Controlling mechanism.Although this system
Realize the stirring successively that many shafts move in circles, adapt to the fermentation process of high impurity material, but this system is by stirring
Mix and reach material conveying and heat transfer (seeing its description the 0027th section).
Anaerobic fermentation tank in above two anaerobic fermentation equipment is all horizontal, and its internal agitating device is mainly used in
Conveying material, does not make solid material being sufficiently mixed in fermentation liquid, and mass transfer is not violent, is not particularly suited for viscosity relatively
Big or that solids content is big fixed-end forces.
CN102952746A disclosed " a kind of anaerobic fermentation tank ", including a tank body and multiple agitator, these agitators
All include a rotary shaft and be positioned at the agitator arm of this rotary shaft one end, the other end of each rotary shaft all with the inwall of this tank body
One join domain in face fixes connection and the axis of each rotary shaft has angle with the normal of this join domain.This fermentation tank leads to
Crossing the form that the normal of join domain that this rotary shaft is arranged to be secured to connect has angle promotes fermentation liquid to form edge
The axial tumble mixed of tank body and/or form the fermentation liquid tumble mixed along tank body radial direction, therefore improve solid material
Distribution consistency degree in fermentation liquid.Agitator in this fermentation tank mainly stirs fermentation liquid, makes fermentation liquid along tank body footpath
To local tumble mixed, it is impossible to enough form overall disturbance from bottom to top in tank body, therefore, the relatively big or solid for viscosity
The solid waste that content is big is also inapplicable.Simultaneously as rotary shaft is installed on the internal face of tank body, manufacture difficulty is relatively big and keeps in repair
Inconvenience.It addition, tank base cannot obtain being sufficiently stirred for of agitator, and it is frequently present of the raw material caused because stirring is uneven
Depositional phenomenon.
Need badly at present and a kind of can efficiently process the viscosity anaerobic fermentation compared with big or that solids content is big solid waste
Equipment.
Summary of the invention
The present invention is directed to the deficiency that existing anaerobic fermentation equipment exists, it is provided that a kind of volume yield rate is high, the suitability is strong, dimension
Protect the highest solid spiral anaerobic reactor.
The solid spiral anaerobic reactor of the height of the present invention, employing following technical proposals:
This device, including tank body and at least one circularly enhancing disturbance unit, each circularly enhancing disturbance unit is arranged at
In tank body；Described circularly enhancing disturbance unit, including actuating device, guide cylinder, rotating shaft and helical blade, actuating device is arranged on
On the top cover of tank body, rotating shaft is connected with the outfan of actuating device, and rotating shaft part in tank body is provided with helical blade, rotating shaft
Being arranged in guide cylinder with helical blade, the upper and lower of guide cylinder is respectively arranged with discharging opening and charging aperture, and guide cylinder sets
Put on actuating device.
An installing hole is offered corresponding to each circularly enhancing disturbance unit on the top cover of described tank body.
In described tank body, the periphery of circularly enhancing disturbance unit is provided with guiding cage, to install or to propose circularly enhancing
It play the guiding role during disturbance unit, it is to avoid mutually scratching.
The upper end of described rotating shaft is installed in bearing block and stretches out this bearing block.
The lower end of described rotating shaft is installed in step.
The sewage outfalls setting of described tank body is at the relative side bottom of the dog-house of tank body, to prevent charging from " short-circuit " occurring
Phenomenon.
Actuating device can use reductor or other can drive the device of axis of rotation.
When said apparatus runs, starting each circularly enhancing disturbance unit, rotating shaft rotates under reductor drives, in rotating shaft
Helical blade drive the material (fermentation liquid and solids) in tank body to promote from the bottom to top, and fallen by top, formed significantly
The circulation of degree ground is stirred, strong mass transfer and strengthening circulation, makes material mixing fully, and mass-transfer efficiency greatly improves.Certain circularly enhancing
Disturbance unit breaks down when needing repairing, and is proposed by tank body.
Material in tank body, by arranging circularly enhancing disturbance unit in tank body, is promoted to fall by the present invention from bottom to top again
Under, make material (including solid and fermentation liquid) form entirety rolling agitation in tank body from bottom to top, the room that bottom is formed is fast
Speed is supplemented by periphery material low level under stress, and therefore, relatively greatly or solid contains to be particularly well-suited to the viscosity such as muddy, high pasty state
The fermentation process of the solid waste of amount big (can reach 20%), strong adaptability, scale can be realized and process；Simultaneously as follow
Ring promotes disturbance unit and can be installed by tank body top, it is possible to overall by proposing maintenance in tank body, facilitates manufacture and maintenance.Separately
Outward, tank body wall and bottoms material have also been obtained and be sufficiently stirred for, and does not results in deposits materials phenomenon.
