Abstract
The utility model relates to a refuse gasification reduction melting incinerator, which consists of a chimney flue, a charge hopper, a side water jacket with a fire-proof material lining, an end water jacket with a fire-proof material lining, an air opening, a branch air tube, a molten slag and alloy outlet opening, a furnace bottom, a blast bustle pipe, a furnace top water jacket, a furnace top handle hole, a furnace top cover plate, a charge belt trolley rail, and a furnace chamber. After the reduction, the gasification and the incineration of the refuse in the four sections: a preheating drying zone, a gasification zone, a reduction incineration zone and a melting zone, the aim of volume reduction, innoxiousness, and resource is achieved, therefore the utility model is in particular suitable for the disposal of used electric appliances and large industrial refuse.
Description
The utility model relates to a kind of New-type refuse vehicle gasification reducing and smelting incinerator.
Along with growing with each passing day of progress, the urban population of expanding economy, society, China city refuse production per capita constantly increases thereupon.The generation of China's domestic waste in 2000 is about 1.5 hundred million tons, and the house refuse of storing up in a large number not only can be caused serious secondary pollution to environment, and cause the huge wasting of resources as if irrational the processing.
The known technology of garbage disposal of China is also quite backward compared with developed countries, most of heap that adopts buries processing, a very little part is used for burning electricity generation etc., heap buries processing and not only takies a large amount of soils, and soil, underground water, atmosphere etc. are worked the mischief, serious environment pollution jeopardizes the human living space.Incineration treatment of garbage technology because have subtracts appearanceization, innoxious and resource effect and the extremely favor of developed country significantly.Domestic incineration treatment of garbage mode mostly is fire grate burning formula greatly, adopts fluidization to burn on a small quantity at present, the overall technology level is lower, on the other hand along with the increase of macromolecular compound content such as plastics in the rubbish, this traditional mode itself can produce new toxic pollutant (as dioxin etc.) again in processing procedure, lime-ash after handling simultaneously fails again to make full use of, the valuable metal in the rubbish does not have fine recovery yet, so existing treatment technology can not adapt to the human kind sustainable development needs.In order to alleviate human survival environment is brought the pressure of destruction, developed country is advocating the zero-emission engineering of garbage disposal.The utility model and the applicant's application number are that 00259909.0 " the direct fusion and gasification, and combustion stove of domestic waste " compared, because all different in the dispensing of its furnace type structure, feeding device, supply air system and auxiliary fuel, thereby be more suitable in the burning of big part industry rubbish.We have proposed innoxious airtight refuse gasification reducing and smelting incineration technology in the utility model, and have successfully developed innoxious airtight refuse gasification reducing and smelting incinerator.This technology not only can suppress the generation of dioxin-like chemical, but also has realized the comprehensive utilization of rubbish.In addition, update along with China urban and rural residents household electrical appliance, a large amount of household electrical appliance such as waste and old television set, computer, refrigerator and washing machine have lost maintenance and have been worth, can only be used as rubbish and be handled, and metal in the part parts of these old household electrical appliances and organic polymer are thoroughly separately also reclaimed very difficulty; The processing of these rubbish by the utility model technology can be burned the macromolecules such as plastics in the rubbish and be changed into heat energy and be used for heat supply or generating, and the metal in the rubbish then liquefy alloy is discharged by furnace bottom and recycled.Realize the resource of rubbish to greatest extent and suppressed the generation of noxious material in the burning process.
The purpose of this utility model is a kind of novel innoxious airtight refuse gasification reducing and smelting incinerator of design, comprising that waste household appliance and big part industrial refuse reach after this stove is handled subtracts appearanceization, innoxious and resource, can not produce new toxic pollutant in the processing procedure, also can realize the comprehensive utilization of cinder, realize the zero-emission of garbage disposal process substantially.
The utility model is to realize by following technical scheme.
Fig. 1 is a front view of the present utility model, and Fig. 2 is a side view.End water jacket 4, air port and branch wind pipe 5, liquid slag and alloy outlet 6, furnace bottom 7, air-supply bustle pipe 8, furnace roof water jacket 9, furnace roof handle hole 10, water jacket beam 11, furnace roof cover plate 12 and reinforced belt track 13 and the burner hearth 14 of its side water jacket 3 by flue 1, loading hopper 2, band refractory lining, band refractory lining are formed.The incinerator main design parameters is as follows: specific capacity 40～100t/ (m
2.d), furnace bottom thickness 0.5～0.8m, 4～10 ° of bosh angle α, tuyere diameter 70～120mm, air port centre-to-centre spacing 200～450mm, 3～10 ° of air port angle of inclination beta, liquid slag outlet (100～200) * (100～200) mm, blast intensity 20～50m
3/ (m
2.min), blast pressure 8～25KPa, the air port is than 2～5%, and particle diameter is that the rubbish of 50～300mm is all applicable.Whole stove adopts the recirculated water cooling, and the cooling water of furnace wall adopts by the bottom entry, and by the top water outlet, the cool cycles of furnace roof is then by an end entry after circulating, after circulating by other end water outlet.
The rubbish that collection is transported is crushed to behind the particle diameter of 50～300mm and additive blending such as lime stone, soda, is added in the stoves by loading hopper 2 then, and auxiliary fuel (as lump coal or moulded coal) also regularly adds from loading hopper; Primary air after the fume afterheat preheating or oxygen enrichment (temperature is 300～800 ℃) are blown in the stove by air port 5 through air-supply bustle pipe 8.Band (600～1250 ℃) and four sections of fusion zone (1250～1450 ℃) are burned in rubbish process preheating and drying band (100～200 ℃), gasification zone (200～600 ℃), reduction successively from top to bottom in stove, and high-temperature combustible gas body that produces after burning and flue gas enter secondary combustion chamber and afterheat boiler electricity-generating system or central heating system by flue 1 and carry out heat utilization; Keep reducing atmosphere in the whole garbage disposal process stove, through gasification zone the time, become semicoke as the polymer substance in the rubbish such as useless computer, useless television set like this with regard to first charing, these semicokes begin reduction at the burning band and burn, and can play the effect of reducing agent, prevent the further oxidation of metal quilt in the rubbish, become the alloy discharge to guarantee the metal in the rubbish.Liquid slag after the burning can be used as building materials etc. after discharging by liquid slag outlet 6, metal species discarded object (mainly referring to contain the parts of old household electrical appliances of metal and the metallic article that still falls together along with house refuse) then becomes alloy in reducing atmosphere, this alloy is also discharged from liquid slag outlet 6 and is recycled, if when the tenor in the rubbish is higher, can establish a metal floss hole in addition; The side furnace wall of whole stove and furnace roof all adopt the recirculated water cooling.
The advantage that has of the design compared with prior art:
1). simple in structure, capital cost is low, is specially adapted to handle industry rubbish such as waste and old television set, computer;
2). the furnace bed index height;
3). valuable metal is easy to reclaim the liquid slag renewable resourceization;
4). the heat that incineration firing produces is easy to recycle;
5). environmental pollution is little;
6). that has realized garbage disposal subtracts appearanceization, innoxious and resource, has realized the zero-emission of garbage disposal process substantially.
