(2) mud sprays in collecting device through sludge incineration device with high speed, in collecting device, collecting is carried out after the sludge incineration sprayed into, oarse-grained mud falls into vitrifying stove, the the first high-temperature plasma torch arranged in vitrifying stove carries out high-temperature plasma vitrifying process to mud, now, the flame temperature of the first high-temperature plasma torch is more than 7000 DEG C; Mud is heated to molten state, and the tailings outlet of mud through bottom of molten state is discharged.
(3) enter pipeline from the small-particle mud of sludge incineration device and flue gas, pipeline is furnished with the second high-temperature plasma torch flue gas and mud granule are arranged, the objectionable constituent in flue gas are processed;
(4) flue gas being mingled with mud granule enters the second collecting device, Granular sludge enters in vitrifying stove along conduit after collecting effect, now, temperature in vitrifying stove is more than 1500 DEG C, mud is heated to molten state, the tailings outlet of mud through bottom of molten state is discharged, and the flue gas after process is discharged from offgas outlet;
(5) temperature in temperature, vitrifying in-furnace temperature and pipeline in the ignition dope flow that Sensor monitoring device internal pressure, mud feeding mouth enter mud flow velocity, ignition dope entrance enter, sludge incineration device, and convert monitoring data to electric signal transmission to PLC automatic control system, by the treating processes of PLC automatic control system control device.
