As shown in figure 1, the organic waste gasification installation of the present embodiment, including body of heater 1, located at the center of the inner bottom part of body of heater 1
Blowing portion, the discharge part located at bottom of furnace body and the feeder at the top of body of heater 3, the top of feeder 3 is provided with feeding mouth 4,
The side of feeding mouth 4 is provided with gas outlet 5, and upper of furnace body is provided with igniting and visits fiery portion 7, and organic waste 2 is deposited in body of heater, from body of heater bottom
Portion forms base grieshoch, anoxycausis layer 9, cleaving layer 8 to top, wherein, base grieshoch is distributed in around blowing portion, blowing portion effect
In anoxycausis layer.Discharge part bottom is provided with supporting part.To rotate out of ash-pan 11, body of heater 1 is located at and rotates out of ash-pan 11 discharge part
Top, fixed by fixing device.Blowing portion includes blower fan, the ventilation unit 14 being connected with blower fan and the cloth wind being connected with ventilation unit 14
Pallet 12, cloth wind pallet 12 include top planes and surrounding inclined-plane, and the ventilation unit 14 being connected with blower fan is in the case where rotating out of ash-pan 11
The cloth wind pallet 12 of portion and bottom of furnace body connects.Igniting visits fiery portion 7 located at side at the top of body of heater.Anoxycausis layer temperature is 900
More than DEG C, material is in anoxycausis layer burning time more than 10 minutes；The temperature of cleaving layer is 400-900 DEG C.
The ash bed of the remaining noncombustible matter self-assembling formation bottom in material afterburnt, as the supplement of base grieshoch, ash
The material bed formation burning zone that slag blanket top is being burnt, the material that burning zone top is accumulated heat caused by lower combustion layer
Heating, reach cracking temperature, form cleaving layer, burning zone is covered by certain thickness cleaving layer material, and passes through adjustment control
With air quantity, anoxycausis state is formed.Base grieshoch is cryosphere, is covered on distributing wind disc and protects distributing wind disc not burnt by high temperature
Ruin, when base grieshoch is more than 200mm, startup rotates out of the ash discharge of ash-pan 11, and for ash from 10,13 discharge around ash-pan 11 is rotated out of, base is grey
When thickness degree is less than 200mm, stop ash discharge.
Top continuous feed, the continuous ash discharge in bottom continuously generate combustible gas 6, gas outlet 5 be it is normally opened, it is caused flammable
Gas continuously fires into follow-up incinerator, and whole gasification, combustion enginnering are continuation, Non-intermittent.Material inlet amount and stove
Air quantity is matched somebody with somebody at bottom, and those skilled in the art can be adjusted within the specific limits according to the technique needs of vapour doses.
The organic waste gasification process of the present embodiment, comprises the following steps：
Step（1）, organic waste be delivered to feeding mouth；
After garbage truck enters factory, the organic matter rubbish such as house refuse, industrial hides, wooden class, unloaded in the discharge bin of sealing
Material is put in storage, then enters disintegrating machine by grapple feeding and carry out attrition crushing, and the material after crushing is conveyed by the belt feeder in sealing passage
Storage bin to sealing is stored, and grapple is provided with storage bin, and material is sent in sealing feeding machine by grapple, will by feeding machine
Material is sent into gasification installation from top to gasify.
Step（2）, organic waste gasification；
Base ash is first inserted in bottom of furnace body, drape wind pallet, base ash can be existing lime-ash etc., and organic waste passes through
Feeding mouth enters gasification installation, from the accumulation started above of bottom of furnace body base grieshoch, when it is material bed be higher than 200mm when, light material,
When bottoms material has largely burnt, continue to feed, adjust inlet amount, keep thickness of feed layer in more than 1.5m.Blowing portion
Air distribution is controlled, forms bottom anoxycausis layer so that temperature reaches more than 900 DEG C, and material is big by the time of anoxycausis layer
In 10 minutes, it is attached to the in one's duty dioxin harmful substance of ash and decomposes completely, residue is the lime-ash of unharmful substance, is beaten
Discharge part is opened, unburned material basic unit and lime-ash are discharged out of the furnace by discharge part, while the CO containing combustible component and H2 generated
High-temperature gas rise naturally, pass through and heat top organic materials, the organic species in the material of top be heated after occur
Cracking reaction, forms cleaving layer, and caused combustible gas is exported outside stove by the gas outlet on feeder top；
Rubbish is sent into from top in closed cracking furnace furnace chamber, and furnace cavity bottom is provided with cloth wind pallet and rotation ash discharge
Disk, rubbish material are accumulated from bottom tray in furnace chamber, are distributed in pallet surrounding, are formed very thick material bed, and thickness of feed layer exists
More than 1.5m.On cloth wind pallet top, using the combustibility of organic matter rubbish, air distribution is controlled by cloth wind pallet, bottom can be formed
More than 900 DEG C of portion anoxycausis region, high-temperature gas of the organic substance anoxycausis generation containing CO and H2, while decompose dioxin
Class harmful substance；High-temperature gas caused by successively, which can pass through, accumulates superincumbent material gap rising, imparts heat to
The rubbish material in portion, the temperature of charge on top increase, and can form 400 DEG C of -900 DEG C of temperature ranges of organic substance cracking,
Organic matter rubbish cracks, and produces the combustible gas containing the composition such as H2, CO, CH4 and CnHm, tar.Under the material of uncracked completion
Drop into burner interval, continue to participate in anoxycausis, until organic matter is totally converted, the non-organic thing of residual, turn into lime-ash, profit
Discharged with ash-pan is gone out.So, top continuous flow rate, bottom continuous blast, ash discharge on demand, it is formed the continuous cracking gas of rubbish
Change process, organic matter rubbish are that cracking gas turns to combustible gas
Step（3）, fuel gas processing；
Combustible gas is sent into incinerator by pipeline, is equipped with combustion air and second-time burning is carried out in incinerator, form 1200
High temperature more than DEG C, incinerator waste gas outlet temperature more than 900 DEG C, air-flow by time of incinerator in more than 21s, it is flammable
The harmful substance remained in gas is thoroughly decomposed, and is generated innocuous substance, is discharged with high-temp waste gas, while be arranged in incinerator
Alkaline filtrate absorb waste gas in dissociate chlorine, sulphur.
In addition, caused high-temp waste gas can heat steam boiler, steam is produced, steam source can be sold.Can also
Using these steam, driving Turbo-generator Set generates electricity, personal or grid-connected sale.Refuse-unloading storehouse and broken storage bin, are adopted
With sealed construction, and air frowzy will be contained by air inducing pipeline, and introduce the furnace bottom air blower and incinerator of gasification furnace
Combustion fan, stink are decomposed completely with combustion air by the high-temperature region of gasification furnace and incinerator, meanwhile, make formation in feed bin micro-
Negative pressure state, prevent stink is excessive from being impacted to ambient air.
Above procedure, the gasification environmentally-friendly for completing house refuse utilize.Organic species in house refuse are converted into
New eco-friendly power source, environment protection emission, while the inorganic matter in rubbish is passed through into high-temperature process, elimination and decomposable harmful substances
Matter, all kinds of bacterial disease opportunistic pathogens are also thoroughly killed, and realize the minimizing and harmless treatment of rubbish.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
