[0010] figure 1 A schematic diagram of a new type of sludge drying treatment device is shown. This new type of sludge drying treatment device includes a feeder 3, which sends the sludge into the sludge drying system. The sludge drying system includes a blower 1, an air heater 2, a disperser 9, and an airflow dryer. 4. Cyclone dryer 5, cyclone separator 6, dust collector 7 and induced draft fan 8. The blower 1 sends the air into the steam-heated air heater 2 to heat, and the hot air above 100°C enters the disperser 9 and enters from the feeder 3 with a moisture content of 80% and is crushed by the disperser 9. The sludge is mixed to form a hot air sludge flow. The sludge in the air sludge flow is dried by the three-stage series air dryer 4 and then enters the cyclone dryer 5 to continue drying, and the dried air sludge flow enters the cyclone separator 6 The dry sludge with a moisture content of less than 5% is separated by centrifugation. The dry sludge is discharged from the...
