Abstract
PURPOSE: To improve a drying efficiency by a method wherein dust of ash discharged from a drier and an incinerating furnace is collected by dust collectors respectively and is returned to a drying process again together with the sludge, in a combined device of a sludge drier and fluidized incinerator.
CONSTITUTION: The dust in a gas discharged from the drier 3 is collected by the dust collector 4 while the dust of ash in the gas discharged from the incinerating furnace 5 is collected by the dust collector 6. The dust collected by these collector 4, 6 is mixed with the dehydrated sludge fed by a mixer 1 in a determined amount, thereafter, is thrown into the other drier 3 through a throwing hopper 9 to dry it by the waste-heat of the incinerating furnace 5. Granulated dried products discharged from the drier 3 are thrown into the fluidized incinerating furnace 5 and are burnt in a fluidized layer by the blow of air generated by a fluidizing fan 8, thereafter, 95W75% of the ash is discharged from an overflow discharging port 7 as the granulated ash.
