Embodiment
The method for describing the domestic garbage pyrolysis gasification production combustible gas of the embodiment of the present invention below.
Included according to the method for the domestic garbage pyrolysis of specific embodiment of the invention gasification production combustible gas：By house refuse
Processing and pyrolysis processing are dried in heat accumulating type rotating bed pyrolysis oven, to obtain rich steam-laden high-temperature oil gas and rubbish
Rubbish charcoal；Gasification process is carried out to the rubbish charcoal as gasifying agent using the steam-laden high-temperature oil gas of richness, to obtain
Gasify gaseous mixture；And the gasification gaseous mixture is subjected to dust separation processing, to obtain combustible gas.
Using the method for the domestic garbage pyrolysis gasification production combustible gas of the above embodiment of the present invention, will effectively can give up
The primary house refuse abandoned step in heat accumulating type rotating bed pyrolysis oven completes drying process and pyrolysis processing, ultimately generates and is rich in
The high-temperature oil gas and rubbish charcoal of vapor.High-temperature oil gas is used as gasifying agent by oil-gas pipeline into fluidized gasification device to be made
With rubbish charcoal can realize the sealed discharging machine discharging of crushing function by the double helix of body of heater, and be sent into fluidized gasification device
Gasification, gasification obtain vaporized mixture and combustible gas product are obtained after dust separation, and foul smell obtains during pyrolytic gasification
Dispel.Whole technical process is just completed by simple flow without pre-treatment step and dries, is pyrolyzed, the purpose of deodorization, finally
Combustible gas is obtained, technological process is short, operating cost is low, and recycling, energy are horizontal high, and product economy is profitable, secondary pollution
Few, no bioxin produces, it is easy to accomplish the industrialization and scale of refuse pyrolysis.
The side of the domestic garbage pyrolysis gasification production combustible gas of the specific embodiment of the invention is described in detail below with reference to Fig. 1
Method.
According to a particular embodiment of the invention, because China's domestic waste is by the way of mixed collection, rubbish group
Into complicated component, including kitchen waste material, plastics, rubber, stationery, wooden bamboo, fabric, glass, metal etc., the water content of the house refuse
One kind is in 40-60%.Therefore, if being dried in pretreatment, it is necessary to substantial amounts of heat smoke or vapor, whether directly
Drying or indirect drying, caused vapor not only measures that big but also the smell is awful, it is necessary to removing stink could discharge, whole mistake
Journey energy consumption is big, and cost is high.Processing and pyrolysis are dried directly by house refuse in heat accumulating type rotating bed pyrolysis oven by the present invention
Processing, and then dry pre-treatment step is eliminated, while substantial amounts of heat smoke or vapor can also be saved, effectively avoid
Vapor a large amount of and that the smell is awful is produced, extra set is eliminated and removes stink equipment, and then save significantly on cost.
Further, since house refuse is mixed collection, component of refuse is complicated, and most techniques are in order to reach higher rubbish
Utilization rate, there is provided extremely complex sorting pretreatment process, and then technological process length, energy consumption is not only resulted in greatly and sorts effect
Rate is difficult to ensure that.Therefore, present invention eliminates sorting step, directly house refuse is carried out in heat accumulating type rotating bed pyrolysis oven
Drying process and pyrolysis processing, and then the various house refuses of complicated component can be all pyrolyzed into rich steam-laden high temperature oil
Gas and rubbish charcoal.Therefore, the method for the domestic garbage pyrolysis gasification production combustible gas of the above embodiment of the present invention can be effective
The defects of ground avoids existing handling process from existing, and effective processing and the recycling of house refuse can be realized.
According to a particular embodiment of the invention, place is dried in above-mentioned house refuse in heat accumulating type rotating bed pyrolysis oven
Reason and pyrolysis processing, to obtain rich steam-laden high-temperature oil gas and rubbish charcoal.According to a particular embodiment of the invention, it is above-mentioned
There is dry area and pyrolysis zone in heat accumulating type rotating bed pyrolysis oven, before the above-mentioned house refuse that process pretreatment is obtained is by dry section
End is fed, and with heat accumulating type rotating bed pyrolysis oven internal rotation, house refuse is dried successively processing and pyrolysis processing, with
Just rich steam-laden high-temperature oil gas and rubbish charcoal are obtained.
According to a particular embodiment of the invention, in dry section drying process temperature be 300-400 DEG C, main function be by
Moisture in rubbish is dried, and the interior drying of stove essentially consists in vapor with drying energy consumption difference outside stove and is increased to stove by 100 DEG C
The sensible heat Q that interior temperature is consumedVapor, because the gasification latent heat of water is very big, QVaporHeat only accounts for 25% of total energy consumption or so, simultaneously
The drying thermal efficiency is relatively low outside stove, and exhaust gas volumn is big, also needs to carry out Odor control containing flue gas frowzy, overall operation expense improves；
The temperature of pyrolysis processing is 600-900 DEG C in pyrolysis zone, is that rubbish completes pyrolysis main reaction region, reaction generation high temperature
Oil gas and rubbish charcoal；Further heated up in the band gas Ye Gai areas frowzy of dry section generation simultaneously, can be smelly by part
Gas is dispelled.
According to a particular embodiment of the invention, caused rubbish charcoal uses sealing double helix discharging machine to discharge and is sent into fluidisation
In bed, double helix is arranged side by side, and spiral is engaged, because rubbish have passed through pyrolytic reaction, plastics therein, fabric, wooden bamboo
Be pyrolyzed Deng organic matter and be different from crude waste for carbide, the carbide, it is loose easily broken, by the stirring of double helix,
Squeezing action, shattering process can be completed while discharging, form the raw material for meeting fluidized gasification.
According to a particular embodiment of the invention, being by the thickness of house refuse cloth in heat accumulating type rotating bed pyrolysis oven can
With 50-250 millimeters.Specifically can suitably it be adjusted according to the type of specific pending organic matter, it is possible thereby to further
Improve the efficiency of dry, pyrolysis and activation process.According to the specific example of the present invention, carried out in heat accumulating type rotating bed pyrolysis oven
