Abstract
The utility model relates to a rotary boiler bed type town refuse pyrolysing gasification burning treatment device, which relates to the field of environment protection. The utility model can be directly applied to incineration and treatment of the refuse in middle and small cities and residual heat utilization for generating the electricity, and the utility model has eligible fume discharge. The rotary boiler bed type town refuse pyrolysing gasification burning treatment device is provided with a burning device. The utility model is characterized in that the burning treatment device is composed of a rotary kiln and residual heat boiler, wherein, the rotary kiln is combined with the residual heat boiler with two burning chambers of vertical arrangement and long flow paths by a narrow movable grate. The utility model is the novel technological equipment which is developed according to national conditions of China. The utility model uses the structural form of a rotary boiler bed and the technology of staged combustion to realize processes of garbage pyrolysis and gasification and clean combustion. The engineering cost is only equivalent to one third to one fourth of the import price, and therefore, the utility model is completely suitable for being popularized and applied in China.
Description
Affiliated field
The utility model rotary kiln bed urban refuse thermal decomposition gasification burning treating apparatus relates to the environmental protection field.Directly apply to small and medium-sized cities incineration treatment of garbage and cogeneration utilization, the flue gas qualified discharge.
Background technology
From global range, incineration treatment of garbage has become municipal refuse and has subtracted one of main means of appearanceization, innoxious and resource, particularly as China one have a vast territory, the big country that the city is numerous, burning disposal will exist as one of main treatment technology in quite over a long time.Waste incineration treatment apparatus mainly contains four kinds of modes: the moving grate incinerator; The swinging incinerator; Fluidized bed incinerator and incinerator.
Summary of the invention
The waste incineration that the purpose of this utility model provides a kind of suitable national conditions thoroughly, clean, and can utilize waste heat produce steam-electric power, the production domesticization cost is low, the waste incineration treatment apparatus that is easy to apply.
The utility model can be achieved through the following technical solutions: a kind of rotary kiln bed urban refuse thermal decomposition gasification burning treating apparatus, incinerator is arranged, characteristics are: incinerating and treating device is made of rotary kiln and waste heat boiler, rotary kiln through narrow formula mobile grate with have one be arranged vertically, the waste heat boiler of long flow process dual firing chamber combines.Adopt rotary kiln and organic cooperation of waste heat boiler constituted a novel waste incineration treatment apparatus.Rubbish enters narrow formula mobile grate and dual firing chamber in the rotary kiln after progressively finishing drying, pyrolytic gasification and partial combustion process under the oxygen debt medium temperature condition, narrow formula mobile grate as the after-combustion section of rotary kiln and have one be arranged vertically, dual firing chamber that flow process is long organically combines.
Wherein, described waste heat boiler is made of narrow formula mobile grate, dual firing chamber, fin panel casing, superheater, economizer, drum, adopts the corner tube type structure.
Described rotary kiln is a kind of rotating at a slow speed by the simplified furnace kiln body of making of steel, and inner lining refractory layer, tilting are arranged, comprise that garbage feeding bucket, pusher, primary air nozzle, kiln outlet are connected with narrow formula mobile grate.
The utility model and conventional boiler difference be have a horizontally disposed narrow formula mobile grate as the after-combustion section of rotary kiln and have one be arranged vertically, dual firing chamber that flow process is long.Under the proportioning of an amount of hot-air, the residue that kilneye falls continues after-flame on fire grate.The combustible gas that pyrolytic gasification produces in the kiln is under an amount of secondary wind proportioning, and fully high temperature after-flame and heat exchange in dual firing chamber makes the dioxin poisonous substance of formation decompose fully in this high-temperature region simultaneously.High-temperature flue gas flows through superheater, economizer successively, finish heat exchanging process cooling after, enter the subsequent technique flow process from exhaust pass, last cleaning flue gases enters atmosphere from chimney.
Superiority of the present utility model is: this device is the novel process equipment according to the China's national situation exploitation, adopt rotary furnace bed structure form and grading combustion technology to realize the technical process of refuse pyrolysis gasification, clean burning, construction costs only is equivalent to 1/3～1/4 of import price, is adapted at China fully and applies.
Description of drawings
Accompanying drawing 1, the utility model structural representation.
Accompanying drawing 2, the utility model fundamental diagram.
The specific embodiment:
Shown in Fig. 1 the utility model structural representation, wherein, rotary kiln 4 is the cylindrical shell of a welded steel plate, inner lining refractory, and tilting is arranged, revolution at a slow speed, the city composting is pushed in the kiln by pusher 2 through garbage feeding bucket 1, stirs with the kiln revolution and stirs, enter air quantity by primary air nozzle 3 controls, under oxygen debt medium temperature condition, progressively finish drying, pyrolytic gasification and partial combustion process.The kiln exit falls into the narrow formula mobile grate 5 of after-combustion section based on the solid residue of charcoal.
Narrow formula mobile grate 5, dual firing chamber 8, fin panel casing 9, superheater 10, economizer 11, drum 12 constitute waste heat boiler, adopt the corner tube type structure.It and conventional boiler difference be have one (1 * 6m) horizontally disposed narrow fire grate as the after-combustion section of rotary kiln and have one be arranged vertically, dual firing chamber 8 that flow process is long.Under the proportioning of an amount of hot-air, the residue that kilneye falls continues after-flame on fire grate.The combustible gas that pyrolytic gasification produces in the kiln is under an amount of secondary wind 7 proportionings, and fully high temperature after-flame and heat exchange in dual firing chamber makes the dioxin poisonous substance of formation decompose fully in this high-temperature region simultaneously.High-temperature flue gas flows through superheater 10, economizer 11 successively, after finishing heat exchanging process and being cooled to about 200 ℃, enters the subsequent technique flow process from exhaust pass 13, and last cleaning flue gases enters atmosphere from chimney.
The present embodiment device is the novel process equipment according to the China's national situation exploitation, adopts rotary furnace bed structure form and grading combustion technology to realize the cogeneration of refuse pyrolysis gas.
Application examples is utilized the utility model, can realize rubbish cogeneration.Its scale and major parameter are:
Garbage disposal production line: 2
Day is handled the city composting: 2 * 150 ton per days
Rotary kiln: 2,3.32 meters of external diameters, long 15 meters
The narrow formula mobile grate of boiler: 2,1 * 6m
Boiler Steam parameter: 2.5Mpa, 350 ℃
Evaporation capacity: 2 * 28 tons/hour
Generated output: 2 * 3000kW
Shown in Fig. 2 the utility model fundamental diagram, earlier industrial refuse is roughly selected broken back and together entered the composting storehouse with house refuse, enter rotary kiln 4 from pusher 2, primary combustion enters in the dual firing chamber 8 and fire grate 5 of waste heat boiler after handling, lime-ash is discharged the back landfill from mucking machine 6, steam is used for the Turbo-generator Set generating, and flue gas is purified with the semidry method purifying column after sack cleaner is discharged from exhaust pass 13, and the solid ash is cured processing.
