The utility model has following outstanding beneficial effect with respect to prior art:
1, rational in infrastructure, simple and practical, the convenient management of tunnel-type kiln of the present utility model, and market low cost, administrative expenses are low, rubbish does not need classification directly to burn, can adapt to the variation of rubbish kind, calorific value, moisture content variation and season and weather, realize the automatic burning of rubbish.
2, tunnel-type kiln main equipment of the present utility model can carry out burning disposal to rubbish without electric power facility and any auxiliary fuel, and disposable igniting just can reach never flame-out effect afterwards, is applicable to away from suburbs and the incomplete place of infrastructure.
3, tunnel-type kiln of the present utility model is dried and solidifies rear the burning at rubbish, adopt silicon photon energy material insulation processed and improve combustion rate in kiln body and burning car, within the of short duration time, allow rubbish fully burn, and can import the second combustion chamber and again heat up and burn and utilize cogeneration, benefit the nation and the people.
4, to rubbish, the residue volume after burning disposal reduces more than 90% tunnel-type kiln of the present utility model, and weight reduces more than 85%, and decrement is effective, processes thoroughly.
5, tunnel-type kiln collection of the present utility model self-feeding, drying, solidify, burning, deashing, dedusting, automation be controlled in one, at dry section, solid tabetisol, incineration area, uses different warm rank disposals of refuse, allows the abundant after-flame of poisonous and harmful substance.

The specific embodiment
Embodiment 1:
As depicted in figs. 1 and 2, the tunnel-type kiln of the present embodiment comprises kiln body 1, the van-type of multihearth bridge construction burns car 2, smoke eliminator 3, the second combustion chamber 4, residual heat using device 11 and generating set 12, described kiln body 1 is divided into dry section 1-1 from left to right successively, Gu tabetisol 1-2, incineration area 1-3 and cooling zone 1-4, described van-type burns car 2 and is provided with trash repository 2-1 and is installed in kiln body 1, described dry section 1-1, Gu tabetisol 1-2 and incineration area 1-3 top are respectively equipped with dry air cavity 5, admittedly the burning air cavity 7 that melts air cavity 6 and comprise several lighting-up tuyeres 8, supplied gas burning and circulation, described dry air cavity 5 is connected with smoke eliminator 3, and the described air cavity 6 that admittedly melts is connected with the second combustion chamber 4 by the first blower fan 9, the second blower fan 10 respectively with burning air cavity 7, and described the second combustion chamber 4, residual heat using device 11 are connected successively with generating set 12.
Wherein, hearth biside wall in the cool furnace of described cooling zone 1-4 is provided with curved channel 13, this curved channel is connected with incineration area 1-3, due in stove in negative pressure state, outside the stink of rubbish can not discharge and come out of the stove, design mechanically-sealing apparatus in burner hearth, to reduce air, enter dry section 1-1 and solid tabetisol 1-2.Described kiln body 1 outer wall adopts steel plate or masonry to pile up and forms, and inwall adopts the siliceous sheet material of photon energy to make, and bottom is provided with sewage collecting tank.Described van-type burns car 2 inner bottom and is provided with skewed automatic ash-discharging mouth, wall adopts the siliceous sheet material of photon energy to make, front and rear portions respectively is provided with the helical form clearance opening, top is provided with dry air cavity 5, admittedly melts air cavity 6 and burns gas flow groove corresponding to air cavity 7, bottom is provided with wheel, and wheel slides on guide rail; The two side, compartment is provided with the ventilation duct of many connections, and bottom is provided with fire bars and triangle pore, so that gas enters.Described every ventilation duct tube wall is provided with irregular aperture, between the ventilation duct of every two connections, with the 15 degree intervals that tilt, puts.Height and width that described van-type burns car are less than dry air cavity 5, admittedly melt air cavity 6 and burn air cavity 7, and gap is 30mm-50mm, and van-type burns car 2 and entered in kiln body 1 by the push rod pushing tow, and push rod promotes by pneumatic or hydraulic thrust motivation.That the siliceous sheet material of described photon energy has is high temperature resistant, improve the thermal efficiency, fully decompose the bioxin texts.
As shown in figures 1 and 3, the incineration treatment of garbage process of the present embodiment is as follows:
1) first will need the rubbish to be processed van-type of packing into to burn the trash repository 2-1 of car 2, trash repository 2-1 will be pushed to dry section 1-1;
2) kiln temperatures of dry section 1-1 is controlled to 50 degree, rubbish is carried out to drying, the moisture content of rubbish is dropped to 2% left and right by 80%, enter solid tabetisol 1-2 after drying;
3) will consolidate consolidating of tabetisol 1-2 and melt furnace temperature and be controlled at 250 degree, under the effect of the siliceous sheet material of photon energy, rubbish will be cured, the combustible species in rubbish is solidified by anoxic, after solidifying, enter incineration area 1-3;
4) the incinerator temperature of incineration area 1-3 is controlled to 850 degree, at the effect down-firing of the siliceous sheet material of photon energy, rubbish is carried out to burning disposal, enter cooling zone 1-4, the cool furnace air amount carries out cooling to rubbish, finally process remaining residue;
5) by ventilation shaft, a part of gas is incorporated into to 1-2De both sides, solid tabetisol and bottom at incineration area 1-3, to consolidate respectively another part gas extraction of gas and the incineration area 1-3 of tabetisol 1-2 with the first blower fan 9 and the second blower fan 10, enter the second combustion chamber 4 and carry out second-time burning, after burning, remaining gas is delivered to residual heat using device 11, residual heat using device 11 imports dry section 1-1 by ventilation shaft by portion gas, and residual gas is generated electricity by steam boiler switching energy and generating set 12;
6) by dry section 1-1, remaining flue gas is introduced chimney by smoke eliminator 3 and is entered atmosphere, and what discharge is surrounding enviroment not to be formed to the steam of any impact, completes whole processing procedure.
