Description
Technical field
The utility model belongs to anaerobic fermentation processing technology field, is related to a kind of anaerobic jar scum silica frost EGR.
Background technology
Big-and-middle-sized scale kitchen garbage biofermentation gas engineering is widelyd popularize in China, and is formed
The industrial system begun to take shape.The characteristics of due to kitchen garbage itself, in the single-phase wet type anaerobic fermentation gas engineering of high temperature, it is
The need for meeting energy balance needed for generator waste heat supply anaerobic jar is heated, and combine the research of early stage factor of created gase, it is ensured that charging
Concentration TS >=8%.Material liquid containing higher TS concentration and high microsteping material (such as capsicum shell, pepper grain, bamboo and wood slag) is being detested
Lamination can be formed in oxygen tank, situations below can occur successively after layering：1) scum layer on top is due to the water of cellulose
Solve speed and be less than production acid and methane phase speed, the microbes of apposition growth absorb the soluble nutrition in kitchen garbage first
Growth and breeding, and form biomembrane on the inert media surface of suspension；2) hydrolysis is resisted when the bond energy formed in water environment to make
Used time, biomembrane can be in solid material superficial growth；3) with biomembrane thickness increase, microbes in biomembrane because
Nutrition can not be obtained in time and self-dissolving, the floatability increase of biomembrane；4) can be inter-adhesive between two biomembranes, by anaerobism potting
Shut and, the permeability of biomembrane is low；5) in anaerobism pot bottom, nutrient consumption tiny microbes totally produce bubble and on
Float and be gathered in biomembrane bottom, cause biomembrane to float；The biogas of generation as the reduction of crust layer permeability and
The accumulation of crust layer bottom, also results in biomembrane floating；6) after biomembrane floats, lightweight material and biology on liquid level
Film then shrinks in the air chamber of anaerobism, is hardened, forming hard crust layer.The hard crust layer harm：11) anaerobic jar is caused
The methane accumulation of interior generation is obstructed, and biogas cannot be introduced into air chamber, thus biogas can not be gathered；12) scum silica frost is resulted even in
Discharge nozzle is blocked, because biogas is imflammable gas, discharge nozzle can cause anaerobic jar to burst after being blocked, and occur security incident.
In summary, if scum silica frost can not be discharged in time, while layering in anaerobic jar with zymotic fluid, product that also can be over time
It is tired, it is more and more, exclude extremely difficult.Therefore, the formation of scum silica frost badly influences the normal of anaerobic fermentation of kitchen waste system
Operation, it is necessary to take reasonable effective measures to minimize influence.
In the prior art, people also a variety of different processes of utility model and equipment attempt scum silica frost to anaerobic jar
It is removed, its processing system, using the stirring etc. downwards of broken shell stirring, plug-flow, is all to re-mix scum silica frost to enter anaerobic jar
In interior biogas slurry, then excluded together with biogas slurry.But these processing systems still have problem：1) shell breaking mixer takes
Business is limited in scope, and when fermentation tank diameter increases, it is only capable of abolishing subregion scum silica frost.And should by scum silica frost skimming device
Part scum silica frost is excluded, and often makes the organic matter direct losses in scum silica frost；2) due to scum layer it is thicker when, scum silica frost can not be mixed completely
Enter in biogas slurry, therefore to the less efficient of scum silica frost exclusion；3) while scum silica frost is excluded, part biogas slurry is also eliminated, seriously
Influence the stability in anaerobic jar.
Utility model content
The purpose of this utility model is there is problem according to above-mentioned existing anaerobic jar scum silica frost removal device there is provided one kind to be used for
Remove the anaerobic jar scum silica frost EGR of scum silica frost.
To achieve these goals, the technical solution of the utility model is as follows：A kind of anaerobic jar scum silica frost EGR, it is special
Levy and be that the anaerobic jar scum silica frost EGR includes
Scum silica frost collection bucket, is arranged in anaerobic jar, for collecting scum silica frost；

Wall；
Pipeline delumper, the input of pipeline delumper is connected with the mozzle other end；
Circulating pump, the charging aperture of the circulating pump and the output end of pipeline delumper are connected, the discharging opening of the circulating pump
Anaerobism pot bottom is connected to by scum silica frost return duct, anaerobism pot bottom is back to for the scum silica frost after will be broken.
According to preferred embodiment of the present utility model, the scum silica frost collection bucket struggles against for cone, a diameter of anaerobism of collection port
With 45-65 ° of horizontal direction angle at the 1/20 ~ 1/10 of tank diameter, cone bucket closing in.
According to preferred embodiment of the present utility model, what the mozzle included being connected with scum silica frost collection bucket bottom oblique leads
Flow tube, the vertical mozzle being connected with the oblique mozzle, vertical mozzle is fixed on anaerobism tank wall by conduit saddle.
According to preferred embodiment of the present utility model, the oblique mozzle is not less than 15 ° with horizontal direction angle.
According to preferred embodiment of the present utility model, the broken particle diameter of the pipeline delumper is in below 5mm.
According to preferred embodiment of the present utility model, the circulating pump uses Pulp pump.
While the utility model can collect scum silica frost, big particle diameter and fibrous scum silica frost are broken by pipeline delumper
It is broken, then anaerobism pot bottom is pumped into by circulating pump, while making scum silica frost damage layer, the organic matter in scum silica frost can be made to be degraded,
Scum silica frost is without outer row, so as to avoid scum silica frost crust and scum silica frost, excessively outer row causes organic matter largely to lose problem, anaerobic jar operation
Stability and gas deliverability all can obtain larger raising, in addition, by circulating pump reflux material can be realized in anaerobic jar from top
Arrive the longitudinal direction stirring at top again to bottom, while can be adjusted by pump flow, control scum silica frost internal circulating load.
