Embodiment Construction
[0026] see Figure 1-Figure 2 Shown, the technical solution that this specific embodiment adopts is: it comprises the following steps:
[0027] Step 1, adding hazardous waste and combustion accelerant into the rotary kiln through the feeder;
[0028] Step 2, start the first burner and rotate the rotary kiln, and burn the hazardous waste in the rotary kiln;
[0029] Step 3, start the pressurizer, feed in pressurized gas, control the combustion temperature in the rotary kiln at 1200°C, and continue burning for 8 minutes;
[0030] Step 4: Start the second burner, and the combustibles processed by the rotary kiln enter the second combustion chamber for combustion treatment. The temperature in the second combustion chamber is controlled at 1200° C., and the residence time of the flue gas is 3 seconds.
[0031] Step 5, the flue gas combusted in the second combustion chamber is discharged from the top.
[0032] In the step 1, the angle between the central axis of the rotary kiln a...
