Description

A kind of combined type incinerator
Technical field
The incineration treatment technology field of solid waste (thing containing dangerous waste) is the utility model is related to, more particularly to a kind of combined type burns Burn device.
Background technology
Solid waste (thing containing dangerous waste) usually needs to carry out processing disposal using burning.To prevent solid waste (thing containing dangerous waste) from burning Secondary pollution is produced during burning, country fires temperature and residence time etc. to the temperature of burning, burnout rate, flue gas two and is made that sternly The regulation of lattice.
Rotation error is because it can adapt to the burning of various fuel, all kinds of solid wastes, and incineration temperature can be up to More than 1100 DEG C, it is widely used in the burning of all types of industries solid waste, rubbish, sludge etc., and dangerous waste is burned.Burned using following current Mode, by controlling solid waste furnace entering volume, fuel dosage, air blast air quantity, kiln rotating speed etc., it is possible to achieve needed for solid waste burning Temperature, residence time, ensure the burnout rate of solid waste;Two burners are connected after Rotation error and design enough capacity, can To realize that sufficient flue gas two fires.
Varied due to entering stove solid waste, it is very big that solid waste burns required time difference, is easily made with stepping into when stove burns It is low into burnout rate, do not meet the requirement of national standard.Therefore, some knockdown incinerating methods are created, such as:Chinese patent CN202792039U discloses a kind of hazardous Waste Incineration technology, the technology remain rotary kiln it is adaptable, On the basis of stable and reliable operation, secondary burning is carried out by the flue gas discharged using grate furnace to rotary kiln, rotary kiln is arranged The waste residue gone out carries out sustained combustion;Chinese patent CN103542415A discloses a kind of combined type sludge incineration device, including returns Rotatable pyrolysis installation, incinerator, waste heat boiler, air preheater and cigarette wind matching device.Patent collection kiln, the pyrolysis gas Change stove, reciprocating grate furnace advantage, swinging pyrolysis gasification furnace therein is accompanied by cigarette wind matching device, using flow, The controllable mixture cigarette wind of temperature, oxygen content, to entering pyrolytic gasification and the anoxycausis that stove sludge is stablized, in its pyrolytic process For caused fuel gas in the presence of system negative pressure, the dual firing chamber into incinerator carries out high temperature incineration processing, the combustion of its anoxic The solid fraction sludge not burnt during burning, falls directly into and continues burning disposal on the reciprocal grate of incinerator.
Above-mentioned two patent solves the problems, such as burnout rate to a certain extent, but can not catch the dust settling in flue gas Collection.Solid waste burning technical specification and standard requirement by national regulation, flying dust caused by solid waste (containing dangerous waste) burning are considered Dangerous waste is, it is necessary to specially treated.Because Rotation error burner hearth wind speed is higher, substantial amounts of solid particle is mixed with caused flue gas Thing, wherein the dust such as the existing solid waste molecule not burnt, fine slag, also there is the flying dust for having adsorbed numerous pollutants.All Trap to form flying dust by dedusting, flying dust amount can be caused to increase severely, processing cost of disposal is high.
The content of the invention
The purpose of this utility model is to provide one kind in place of overcome the deficiencies in the prior art and be used for solid waste including danger Dangerous waste is fully burnt, flue gas two fires and dust catching once burns the combined type incinerator of completion.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is:A kind of group for incinerating method Box-like incinerator, including:Rotation error, fluidized bed incinerator and the burner of Horizontal sedimentation two, the Rotation error Fluidized bed incinerator is connected, the fluidized bed incinerator connects the burner of Horizontal sedimentation two.
The Rotation error and fluidized bed incinerator directly in conjunction with:The fluidized bed incinerator fires with Horizontal sedimentation two Stove directly in conjunction with.
The fluidized bed incinerator side connects with the Rotation error, receive Rotation error from top to bottom from What kiln hood to kiln tail was fallen into does not burn waste;The opposite side of the fluidized bed incinerator connects with the burner of Horizontal sedimentation two, Flue gas is delivered to the burning of the burner of Horizontal sedimentation two.
The burner stage casing of Horizontal sedimentation two is provided with ammonia atomization nozzle, to furnace injection ammoniacal liquor.
Dust settling capturing device is provided with the burner of Horizontal sedimentation two.
The fluidized bed incinerator top is provided with post-blast device.
The fluidized bed incinerator top is provided with burner.
The beneficial effects of the utility model are:1) reduce the pre-treatment working strength of solid waste burning, only need to pass through letter Single compatibility is burned with controlling the content of melt substance to enter stove.Wherein inflammable material is filled in Rotation error Divide burning disposal, produce a small amount of lime-ash and enter fluid bed furnace.Because nonflammable material passes through the burning of kiln for a period of time Afterwards, enter back into fluid bed furnace and continue to burn, the burnout rate of nonflammable material can be improved, it is ensured that production capacity or increase production capacity.
2) because fluid bed furnace has shared part burning amount, the body of heater of kiln is caused to reduce when production capacity is constant, together When a kiln air blast reduce, air distribution coefficient is 1.0~1.2;Fluid bed furnace increases post-blast, and air distribution coefficient is 1.6 ~2.0, it is ensured that two combustions of residue and flue gas so that the air distribution of burning process more conforms to the low air distribution of kiln and fluid bed furnace The combustion characteristics of high air distribution.
3) when carrying out dangerous solid waste burning, kiln incineration temperature directly can be risen to 1100 DEG C;Into fluidisation After pool furnace, residue falls into the fluid bed furnace of lower position, under the effect of fluid bed furnace air distribution temperature decline and maintain 900 DEG C Continue to burn;1100 DEG C of high-temperature flue gas directly enters the burner of Horizontal sedimentation two from fluid bed furnace top, is matched somebody with somebody by post-blast Than making fuel gas therein etc. fully burn, and 1100 DEG C of burning is maintained, save secondary combustion-supporting fuel.Similarly, carrying out When general solid waste is burned, it can also cancel secondary combustion-supporting.
4) two burners with Horizontal sedimentation structure provide two enough combustion spaces, it is ensured that gas residence time, and it is real The function of chalk dust removing is showed.
