The present invention is a kind of processing method of more material combined ferment dry anaerobic digestion complexes, including following step
It is rapid:
1, rubbish from cooking filters out suitable perishable rubbish after the purification of front end pretreatment workshop, conveys through the first supplied materials belt 1
To the first timing dispenser 9；First timing dispenser 9 presses program setting, at regular time and quantity by perishable rubbish conveying discharging to first
Splicing belt 3；Then it is delivered at the lower end of refining belt 5 again.
2, other rubbish (garden garbage, stalk etc.) of joint disposition, by manually or mechanically feeding to the second supplied materials belt 2
Place；The reception bucket of subsequent conveying and blanking to crusher 7 falls in the second timing dispenser after crusher is crushed to suitable particle diameter
8；Second timing dispenser 8 can be by program setting, at regular time and quantity by other rubbish conveying discharging to the second splicing belt 4；Then
It is delivered at the upper end of refining belt 5 again.
The effect of the first timing dispenser 9 and the discharging of the second timing dispenser 8 is to guarantee different types of material
Output is uniform, to guarantee that subsequent material is uniformly mixed.
3, the lower end of refining belt 5 is delivered up after receiving perishable rubbish, until other rubbish are received when at upper end again, with
After be delivered to distributing belt 6.
The effect of the refining belt 5 is that perishable rubbish and two layers of other rubbish point are layered on belt, plays mixing
Purpose facilitates subsequent material processing.
4, mixed material is supreme containing in solid material storage silo 10 through 6 conveying and blanking of distributing belt.
The high effect containing solid material storage silo 10 is that temporary and pre fermentation can be carried out to material, ensures material supply
Steadily, safety.
5, high material containing solid mixture enters anaerobic digestor 24 through splicing spiral 11, conveyor screw 12 and feed auger 13
It is interior, carry out anaerobic digestion disposition.
The effect of the described spiral way conveying is uniformly to convey, it is ensured that material conveying uniform and equal into tank material
It is even, to improve the stability and safety of the digested environment of anaerobic digestor 24.
The effect of the feed auger 13:
(1) high-order feed auger, charging port are arranged in the upper position and tank of anaerobism tank body under the liquid level of anaerobic sludge
End, material is smaller into tank resistance, and feed auger thrust or energy consumption are lower.
(2) feed auger exit is smaller by the reverse extrusion power of material in tank, does not need to prevent tank by material plug
Interior material backflows, and configuration and operation are easy, stable, safety coefficient is high.
(3) feed auger outlet end higher position in tank avoids material from directly falling in bottom in tank, causes in material
Inert impurities are easy to cause stirring difficult after being deposited on bottom.
(4) feed auger outlet end is arranged in tank below material liquid plane, and biogas in tank is avoided to reveal.
6, feed auger 13 and 24 junction of anaerobic digestor are equipped with the first charging safety-valve 14.
The first charging effect of safety-valve 14 is carried out when spiral is overhauled or charging failure need to shut down cleaning
It closes, prevents material in tank from backflowing.
7, pasty material (such as excrement, sludge) contains at solid material storage silo 15 through the direct discharging of discharging platform 34 to low.
Subsequent start-up blender 16 mix mixed.
The blender 16 effect be by it is agglomerating in pasty material, at blocky material scattering, beat uniformly, raising material
Uniformity and mobility.
8, pasty material is entered in anaerobic digestor 24 through closed conveying pipeline 18 and is disposed by starting delivery pump 17.
The cleaning pipe 19 for being connected to water, cleaning pipeline valve has been respectively configured in 18 rear and front end of closed conveying pipeline
20 and sewage pipe 23, sewage draining valve 22 and second charging safety-valve 21, when pasty material interrupt charging it is small more than 24 when, be
The hardening of deposition material, blocking pipeline in closed conveying pipeline are prevented, the second charging safety-valve 21 need to be closed immediately and open cleaning
Pipeline valve 20, sewage draining valve 2, access high pressure tap water, which rinses material in pipeline to sewage grit chamber, to be disposed.
9, after various materials (perishable rubbish, other rubbish, pasty material) enter in anaerobic digestor 24, agitated system
25 agitation operations, flow to the other end (outlet end) from one end (input end) of digester.
The effect of the stirring system 25:
(1) multiple agitating shafts (quantity can configure under normal circumstances 5 or 7 according to scale of the project flexible configuration), stirring are configured with
Axis is combined using two kinds of blade (4 blades and 2 blades are respectively configured) compartment, passes through intermediate driving
Driving motor of the axis at the outer both ends of anaerobic digestor 24 drives rotation.
(2) the knockdown effect of two types agitating shaft is that stirring region maximizes, without dead angle, while in turn, ensuring that stirring
Adjacent agitating shaft blade will not be touched when operating, guarantee operational safety.
The agitating shaft drive manner effect
(1) compartment operation, continous way operation or great-jump-forward operation can be set as according to 33 program of anaerobism DCS control system terminal
Equal various ways meet stirring needs of the different material within the different fermentations period from each other without interruption.
(2) rotation speed and the direction of rotation that can adjust different agitating shafts are more convenient in manipulation adjustment anaerobic fermentation tank
Yeasting, for example when material viscosity is lower, to avoid inert impurities from settling, can accelerate to rotate；When material viscosity compared with
Gao Shi can slow down rotation.
(3) the various products distribution after can making the material of regional area in anaerobic digestor 24, strain and fermentation is more
Uniformly, fermentation is more abundant, fermentation efficiency is higher；
(4) it can avoid that the inert impurities in material are deposited on bottom or when soft impurity swims in top gives system operation bring
Risk；
(5) inert impurities of 24 Nei Zhong lower layer of anaerobic digestor and bottom deposit can be made by agitation mode, from material inlet end
It is mobile to outlet end, be finally discharged from discharge duct, avoid detesting caused after a large amount of inert impurities of deposition in anaerobic digestor 24 be
System risk.
(6) biogas for generation of fermenting in material body in anaerobic digestor 24 can be released, avoids biogas from accumulating and is detesting
In oxygen sludge body；
10, various materials are after the digestion of anaerobic digestor 24, from the discharging of discharging workshop.Discharge way can be controlled by anaerobism DCS
33 fully automatic operation of terminal system, main flow are as follows:
(1) after first emptying air in vacuum tank 28 naturally, start vacuum pump 31 for 28 vacuum state of vacuum tank.
It (2) then will be in discharge of materials to vacuum tank 28 in anaerobic digestor 24 by discharge duct 27.
(3) evaporation plant is emitted into from delivery pipe 29 finally by material in pressure-air promotion vacuum tank 28.
(4) above-mentioned (1) step is repeated, cycle operation is until material in anaerobic digestor 24 stops discharging.
The above is only the preferred embodiment of the present invention, therefore cannot be limited the scope of implementation of the present invention with this, i.e., according to
Equivalent changes and modifications made by scope of the present invention patent and description should still belong to the model that the invention patent covers
In enclosing.
