Abstract
In this paper, according to the type and scale of hazardous waste incineration, process selection, design of rotary kiln incinerator, and the engineering principle and performance characteristics of rotary kiln incinerator system are analysed, and the proposed method is verified by practical engineering examples. The results showed that the temperature of rotary kiln is controlled at about 850 °C, the residence time of hazardous waste in rotary kiln is about 60min, the rotating speed is 0.88r/min, and the inclination angle is 1.75. The temperature of the second combustion chamber is more than 1100 °C, and the residence time of flue gas in the second combustion chamber is more than 2S. After continuous incineration, the reduction rate of slag ignition is less than 5%, the removal rate of fly ash is more than 99.99%, and the flue gas is discharged up to the standard.
