Description
Technical field
The present invention relates to solid waste incineration stove technical field, particularly a kind of solid waste incineration stove of smokeless.
Background technology
Solid waste comprises: town pavement sweeping rubbish, domestic garbage, food garbage, medical waste, processing of farm products discarded object, ight soil, waste or used plastics, tire, organic sludge and danger wastes such as leather-making mud, electroplating sludge, printing and dyeing sludge etc.The incinerator of conventional garbage burning electricity generation factory generally carries out burn processing to rubbish in 800～900 ℃ of scopes, the incinerator of garbage incinerating power plant is impossible burning disposal medical waste or mud the like waste, more can not the burning disposal danger wastes.Incinerator for medical garbage generally requires furnace temperature to reach 1200 ℃, and existing incinerator for medical garbage need add a large amount of fuel auxiliary combustions, and operating cost is high, handles so also can not be used for consumer waste incineration.For the high Litters such as mud of water content, existing also do not have the special furnace set burning disposal, generally all is landfill disposal after the employing mummification.Can not use same body of heater burning disposal to house refuse, medical waste, organic sludge and danger wastes in the existing incinerator, must go to handle respectively with special-purpose incinerator.And these special-purpose incinerators only are the few partial heat energies that has utilized combustion process, a large amount of fume emissions are arranged in burning process certainly and cause secondary pollution.
At present, be used for the incinerator that solid waste handles and mainly contain mechanical kiln grate furnace, fluidized bed incinerator, swinging incinerator, static pyrogenation incinerator, small-sized oil and gas stove etc.Generally be divided into three sections in its burner hearth of mechanical kiln grate furnace the most commonly used, i.e. dryer section, burning zone and burning segment.Fluid bed is mainly by being used to keep coal body flow air dispersal device, incombustible discharger, incombustible screening and coal body EGR etc. to form.Rotary kiln is the cylinder interior at steel; Install refractory liner additional and porose steel plate is welded into tubular; With the solid waste direction of transfer is the axle center, is the equipment of small angle inclination rotation, its outer two groups of ring-type steel wheel rims and several roller sliding bearing of being with; Cylinder is rotated slowly, and solid waste is stirred and is fed forward.All there is following weak point in these incinerators: the ignition temperature in (1), burner hearth internal combustion district is in 800-900 ℃ of scopes, and ignition temperature is low, and combustion efficiency is poor, can produce pernicious gases such as a large amount of dioxin; (2), can a large amount of flue gases of discharging in combustion process (the pernicious gas dioxin that produces like nitrogen oxide, carbon dioxide, sulfur dioxide and because of imperfect combustion etc.) cause secondary pollution; (3), combustion process adds auxiliary fuel (like coal, diesel oil etc.) and causes the burning cost up, and consumes mass energy, causes the wasting of resources; (4), because the combustion adjuvant that in combustion process, uses of rubbish is an air, and airborne nitrogen is not participate in combustion reaction, and it absorbs great amount of heat again, heat energy loss is big, the thermal efficiency is low thereby cause.In a word, these furnace body complex structures, combustion space are greatly, the bubbling air amount is big, smoke discharge amount is big, dust is many, heat energy loss is big, neither energy-conservation also not environmental protection.
Flue gas in the existing solid waste incineration stove all be through smoke stack emission in atmosphere.Owing to flue gas is handled and reasons such as operating cost height or smoke processing system maintenance disappearance; Cause a large amount of flue gases to contain poisonous pernicious gas (as: sulfur dioxide, carbon monoxide, nitrogen oxide, dioxin etc.) and fly ash emission; Surrounding air, water source and soil are caused severe contamination, and these flue gases discharge the entail dangers to existent environment of people for a long time.
Owing to there is a large amount of flue gases constantly to discharge, the heat of solid waste incineration can be pulled away a part along with fume emission descends furnace temperature in the existing solid waste incineration stove; And,, need garbage drying in advance so be difficult to burning because solid waste contains washiness and calorific value is low, and this just needs a large amount of hot-airs, and the heat in the burner hearth has been consumed a part again, makes furnace temperature decline; Simultaneously, because the combustion space of incinerator is big, burner hearth inner surface area of dissipation is big, radiating rate is fast and heat dissipation capacity is big, and the heat energy in the burner hearth is consumed a part again, and furnace temperature is descended, and causes the thermal efficiency of whole incinerator low.
The combustion adjuvant of participating in the combustion oxidation reaction in the existing solid waste incineration stove all is to adopt airborne oxygen; Because the composition of solid waste is comparatively complicated, its calorific value difference is big, causes furnace temperature unstable; When the calorific value of incinerated matter hangs down; It is stable to keep furnace temperature generally can to add exotic fuels such as diesel oil or coal, consumes the part energy so again, and the plastics under the oxidant condition is arranged in the solid waste burn when insufficient; Can produce a large amount of toxic and harmfuls such as dioxin, cause serious environmental to pollute.The air capacity that need strengthen usually in the entering burner hearth of burning fully of solid waste is held mobility to increase; Let and in burner hearth, form fluidized state between air and the solid waste; But so can cause flying dust amount increase in the flue gas, make the increase of gas cleaning intractability and cause processing cost to increase.
