System 08, is provided with the induction furnace 03 for storing and discharge liquid slag bottom superhigh temperature pyrolytic gasification melting furnace body of heater 01,
Induction furnace 03 is removably circumscribed with fiberizer 02, and superhigh temperature pyrolytic gasification melting furnace body of heater 01 is by flue 04 and dust
Device 05 connects, and is provided with combustion furnace 06 and heat exchanger 07 integrated heat supply equipment or Two-way Cycle electricity generation system 08, changes after dust arrester 05
Hot device 07 is connected to 06 top of combustion furnace by welding manner.
A kind of method of solid waste resource recovery is as follows:
(1) after igniting, superhigh temperature pyrolytic gasification melting furnace body of heater 01 is brought rapidly up, and body of heater 01 temperature is rapid within half an hour
It is warming up to 800-900 DEG C.
(2) the three road valve that solid waste opens and closes successively through superhigh temperature pyrolytic gasification melting furnace 01 porch are (in figure
Not shown) and slowly decline, the time of staying in body of heater 01 is up to 4-6h, fully can burn in body of heater 01, three road valve
Specific works process is as follows: time initial, three road valve are turned off, when solid waste is fed through first valve, and first
Valve is opened, and solid waste is all by after in first valve and when being fed through second valve, and first valve is closed
And second valve opens, solid waste all by after in second valve and when being fed through the 3rd road valve, second
Valve is closed and the 3rd road valve is opened, solid waste all by time in the 3rd road valve described body of heater of entrance, the 3rd road
Valve is closed.Three road valve are steel, and exterior material is the pink fused alumina of high alumina refractories, and marginal portion is around carborundum grain
Fine and close permanent inert layer, there is excellent high temperature resistant property and sealing property, material enters superelevation warm through three road valve
When solving melting furnace, three road valve open and close successively, it is ensured that stove internal contamination thing is the most excessive, prevents thermal loss simultaneously.Body of heater 01
Interior operating temperature is 1500 DEG C-3000 DEG C, and excess air factor α is 1.1-1.3, and solid waste is sent out when burning in body of heater 01
Raw main chemical reaction is as follows:
FeO+C→Fe↓+CO↑；
ZnO+C→Zn↓+CO↑；
PbO+C→Pb↓+CO↑；
CO2+C→2CO↑；
H2O+C→H2+CO↑；
Less owing to producing sour gas in body of heater, fat lime stone can be added in body of heater 01 and carry out deacidification in stove, and
Extracting tower need not be set after incinerator.Solid waste burn in body of heater 01 produce all liquid slags of slag, storage
In there is cylindrical induction furnace 03 and timing is discharged, the deslagging cycle is 0.5-5h, the operating temperature of induction furnace 03 is 1500 DEG C-
3000 DEG C, the liquid slag of discharge enters in fiberizer 02 and can be used for making fiber.
(3) the substantial amounts of vapours produced in body of heater 01 and two kinds of fuel gas CO and H2Can be entered it through dust arrester 05
After combustion furnace 06 and heat exchanger 07 integration apparatus for heat supply or enter Two-way Cycle electricity generation system 08 be used for generating electricity, life per ton
Rubbish of living can generate electricity 400 kilowatt hours.
(4), after solid waste is all burnt, lower the temperature after stopping working, can be by arranging cooling water pipe in body of heater 01 exterior circumferential
Cooling rapidly.
The liquid slag produced due to solid waste in burning process includes: inorganic non-metallic slag and slag,
The metals such as Fe, Zn and Pb form liquid metal alloy in being gathered in induction furnace 03 with elemental stage, can be on induction furnace 03 body of heater
High-temperature resistant silicon carbide hangs brick and high-temperature resistant silicon carbide is hung and is previously provided with preformed hole position on the furnace wall drilled through between brick, profit
Substantially can be layered with other liquid inorganic matters more greatly with slag proportion, can be by liquid metal alloy slag individually from induction furnace
Discharge in 03, also can be as nichrome sold after cooling.
Induction furnace 03 tapping process is as follows: when needing to carry out liquid row in superhigh temperature pyrolytic gasification melting furnace 01 running
During slag, the mechanical arm with tungsten bur hole in induction furnace outer wall preformed hole precalculated position, until drilling through induction furnace 03
Body of heater, enter the space hanging brick and hanging between brick, extract drill bit, slag tap can be realized；After deslagging, with carbonization
The mechanical arm of tungsten drill bit is slowly advanced by original route, and in hole, a small amount of liquid slag condenses, by hole under the cooling effect of air
Closing, mechanical arm stops advancing, and extracts drill bit, and slag tap process i.e. terminates.In tapping process, unsuitable double use
Drill bit is holed on same preformed hole precalculated position and is carried out slag tap.
With reference to Fig. 3 and Fig. 4, containing a large amount of two English in the flying dust trapped due to dust arrester 05 and flue gas, can be in superhigh temperature
Cooling tower 09 is set between pyrolytic gasification melting furnace 01 and dust arrester 05 and suppresses closing again of two English for cooling down flying dust and flue gas
Become.Also follow in the flying dust that dust arrester 05 is collected can be delivered to superhigh temperature pyrolytic gasification melting furnace 01 by airduct 10 by blower fan simultaneously
Ring burns, it is ensured that the outer row of two English produced in system, and it is 300～500kPa that whole wind passes through blast in Cheng Fengguan 10.
Principle and the embodiment of the present invention are set forth by specific case used herein, saying of above example
Bright it be only intended to help and understand assembly of the invention and core concept thereof；Simultaneously for one of ordinary skill in the art, foundation
The thought of the present invention, the most all will change, and in sum, this specification content is not
It is interpreted as limitation of the present invention.
