Specific embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is described.
As shown in figure 1, danger waste burning furnace system generally includes waste pretreatment system, feeding system, CIU, flue gas
Several part such as cleaning treatment system.Waste pretreatment system includes pretreatment and the feed process of waste, and industrial hazard is discarded
Thing is transported to the center of disposal storehouse by special-purpose vehicle, and the broken material of needs is grabbed to hang by driving after crusher in crushing, compatibility and sent
Enter kiln hood charging aperture on operating platform, sent into back by hydraulic pressure material-pulling device 1 after two-stage hydraulic pressure insertion plate door in kiln hood charging aperture
Rotary kiln 2.
CIU by rotary kiln 2 and dual firing chamber 3, slag tap and control system forms；Rotary kiln 2 burns the flue gas producing and enters
Enter dual firing chamber 3, in dual firing chamber 3, spray into air and combustion gas or fuel oil so as to abundant burn, and ensure flue gas in dual firing chamber 3
1100 DEG C of temperatures above area time of staying are more than 2 seconds, destroy dioxin by fire with high temperature.
System for cleaning fume is absorbed by waste heat recovery, chilling, dry type reactor 6 and cleaner, sour gas, cigarette
Gas reheating, except dioxin equipment composition.The high-temperature flue gas that dual firing chamber 3 produces enter waste heat boiler 4, and recovery section energy production is steamed
Vapour, steam is available for factory steam and other vapour by gas-distributing cylinder.The sedimentation interior entering waste heat boiler 4 in flue gas is provided with de-
Nitre system is it is ensured that the index of exhaust emissions NOX.Flue gas temperature after waste heat boiler 4 drops to 500 DEG C～550 DEG C, and flue gas directly enters
