[specific embodiment]
Referring to accompanying drawing, a kind of vertical daily garbage incinerator, body of heater is the vertical cylinder of an inner lining refractory, one combustion chamber 4 and dual firing chamber's 1 coaxial arranged in series, the centre is separated by sphere arch 2, sphere arch 2 is inside and outside hemisphere face shape, form by stainless steel insert and the casting of fire-resistant casting material, every putting one, on the interface brick wall of dual firing chamber, it makes a combustion chamber and dual firing chamber be separated into two relatively independent combustion chambers, can prevent the short circuit of high-temperature flue gas, because penetrating with interception, the width of cloth of arch strengthens the burning of rubbish again in dual firing chamber, the peripheral brick of sphere arch is provided with annular mixing chamber 3 within the walls, mixing chamber 3 is a cyclic structure, top is column type, the bottom is conical, flame hole 13,14 are arranged in a mixing chamber and a combustion chamber, on the partition wall between the dual firing chamber, mixing chamber is by flame hole 13,14 are communicated with a combustion chamber and dual firing chamber respectively, the design feature of mixing chamber is that decapacitation is strengthened outside the immixture of high-temperature flue gas and secondary wind, still can play the effect of dust-settling compartment, the big particulate trap of carrying secretly in the flue gas is fallen and fall after rise to firing in the chamber along the inclined-plane, reduce the dustiness that kiln gas, improve burnout rate, the body of heater lower disposed has profile of tooth moving grate 5,7, constitute again burning chamber 6 between the two.The profile of tooth moving grate is fixed on the swinging axle by staggered profile of tooth fire grate segment to be formed, incinerator is in service, regularly open fire grate 5, incineration residue is fallen on the fire grate 7, close fire grate 5 then and behind setting-up time, open fire grate 7 again, the slag in afterburnt is discharged out of the furnace, this architectural feature is to prolong incineration residue at residing time in furnace, reduce hot burn decrement rate, the body of heater side is provided with the chute 8 that pusher is housed, the entrance point of chute 8 is connected with the discharging opening of revolution oven dry (batching) device 9, the port of export and a combustion chamber communicate, and rubbish advances the moisture in the stokehold oven dry rubbish, when refuse thermal value on the low side, can be when needing coal blending to improve into the stove refuse thermal value with material, coal mixes, one time wind is divided into end wind and waist wind in proportion, respectively by air inlet 10,11 enter a combustion chamber, and air inlet 10 is located on the furnace bottom ash chamber, end wind is gone into stove thus, helps the remaining combustible in the burning chamber to burn again; Air inlet 11 is located at the burning zone periphery, its wind directly is blown into burning zone, strengthen incineration firing, secondary wind air inlet 12 is located at the mixing chamber periphery, secondary wind tangentially enters mixing chamber, strengthens flue gas and mixes with air, and this stove one combustion chamber is provided with and opens burner in addition, dual firing chamber is provided with booster burners, in order to improve burning control.
During use, primary house refuse is sent into revolution oven dry (batching) device 9 through conveyer dries wherein and enters chute 8 behind the moisture content, pushes one by the pusher of chute 8 bottoms by design material amount and fires chamber 4.Advance stove rubbish in the furnace high-temperature environment, be subjected to respectively the combustion-supporting effect of a wind sending into by furnace bottom and periphery rapid fire burns.By the air quantity of controlling a wind one combustion room temperature is maintained in 760～850 ℃ of scopes.The interception changed course that the high-temperature flue gas of one combustion chamber upwards is subjected to sphere arch 2 enters mixing chamber by the flame hole 13 of side, and the big particle of carrying secretly in the flue gas returns in the flame because of collision and burns away, burns simultaneously.Enter the high-temperature flue gas of mixing chamber and mix the back is entered top by flame hole 14 dual firing chamber's 1 continuation high-temp combustion with the secondary wind that tangentially enters mixing chamber.By the reasonable preparation of primary and secondary air, can effectively guarantee ignition temperature 〉=850 ℃ of dual firing chamber, the combustible component in the flue gas is burnt, poisonous, harmful components are decomposed fully, are destroyed by fire, guarantee kiln gas qualified discharge after follow-up vent gas treatment.The flue gas that enters mixing chamber 3 makes the big particulate trap of carrying secretly in the flue gas in the process of collision and changed course in stove, has reduced the dustiness that kiln gas effectively, has alleviated the load of follow-up tail gas treatment device.Incineration residue in the one combustion chamber 4 enters burning chamber again by the profile of tooth moving grate of regularly opening 5, thoroughly burns under a wind action of preheating.The setting of burning chamber again, the controlled burn decrement rate that heats be below 2%, is better than 5% requirement of national Specification.
The utility model is suitable for the following scale of burning disposal 150t/d, advances the domestic waste of stove calorific value 〉=1200kcal.
