Electricity generation system 08, is provided with the induction furnace for storing and discharge liquid slag bottom superhigh temperature pyrolytic gasification melting furnace body of heater 01
03, induction furnace 03 is removably circumscribed with fiberizer 02, superhigh temperature pyrolytic gasification melting furnace body of heater 01 by flue 04 with
Dust arrester 05 connects, and is provided with combustion furnace 06 and heat exchanger 07 integrated heat supply equipment or Two-way Cycle electricity generation system after dust arrester 05
08, heat exchanger 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
