Specific embodiment
Specific embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in Figure 1, dangerous waste incinerator system generally includes waste pretreatment system, feeding system, incineration system, flue gas
Several parts such as cleaning treatment system.Waste pretreatment system includes the pretreatment and feed process of waste, and industrial hazard is discarded
Object is transported by special-purpose vehicle to disposition center storehouse, is needed broken material to be crushed crusher machine, is grabbed to hang by driving after compatibility and send
Enter kiln hood feed inlet on operating platform, is sent into back after kiln hood feed inlet is by the hydraulic insertion plate door of two-stage by hydraulic material-pulling device 1
Rotary kiln 2.
Incineration system by rotary kiln 2 and dual firing chamber 3, slag tap and control system forms；Rotary kiln 2 burn generate flue gas into
Enter dual firing chamber 3, in dual firing chamber 3, sprays into air and combustion gas or fuel oil, make its full combustion, and guarantee flue gas in dual firing chamber 3
1100 DEG C of temperatures above area residence times are greater than 2 seconds, destroy dioxin by fire with high temperature.
System for cleaning fume is by waste heat recycling, chilling, dry type reactor 6 and cleaner, sour gas absorption, cigarette
Gas reheating, except dioxin equipment forms.The high-temperature flue gas that dual firing chamber 3 generates enters waste heat boiler 4, and recovery section energy production is steamed
Vapour, steam for factory steam and other use vapour by gas-distributing cylinder.It is provided in the expansion chamber that flue gas enters waste heat boiler 4 de-
Nitre system, 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, flue gas directly into
Cooling water is sprayed in chilling tower 5, completes to be down to 200 DEG C of chilling from 500 DEG C in 1 second, ensure that flue gas purification system is transported
Capable stability and reliability.In the exhanst gas outlet of chilling tower 5 to dry type reactor 6 is provided between bag filter 7, at it
The middle injection for carrying out Activity of Lime charcoal, active carbon powder carry out the heavy metal in flue gas with possible regenerated dioxin-like chemical
