Beschreibung
Zusammenfassung:	The invention discloses a slag type rotary kiln for hazardous waste incineration, the interior of the rotary kiln is sequentially divided into a feeding zone, a drying zone, a combustion zone and a burnout zone, the temperature of the feeding zone is 800-850 DEG C, the temperature of the drying zone is 800-1050 DEG C, the temperature of the combustion zone is 1050-1450 DEG C, and the temperature of the burnout zone is 1000-1050 DEG C; and the temperature of the rotary kiln partition is controlled to keep the hazardous waste in the rotary kiln in a molten state during operation of the rotary kiln. A barrel body of the rotary kiln is lined with a fire-resistant heat-insulating material, a kiln coating is built on the surface of the fire-resistant heat-insulating material, and the kiln tail of the rotary kiln adopts necking reducing. The rotary kiln is high in heat efficiency and low in operation cost, the high temperature resistance and corrosion resistance of the rotary kiln are optimized, and the service life
