SLUDGE DRYING DEVICE

摘要

The present invention relates to a sludge drying device which dramatically reduces abrasion of a facility since not using a mechanical device of a direct contact method such as grinding for a secondary drying furnace in a drying facility. The sludge drying device comprises: a supply feeder consecutively supplying a sludge where moisture, injected through a hopper, is included; a hot air dryer drying with hot air while moving the sludge received from the supply feeder; a fluidization dryer which dries while moving by making the sludge, passed through the hot air dryer, fluidized; a dried sludge storage tank storing the dried sludge which is discharged from the fluidization dryer; and a burner supplying fluidized gas to the fluidization dryer, and supplying combustion gas to the hot air dryer by the hot air.
