ORGANIC SLUDGE DRYING SYSTEM AND DRYING METHOD

WIPO Patent Application WO/2011/018977

A1

Provided is an organic sludge drying system and the like which makes it possible to reduce the size of the organic sludge treatment facility and efficiently treat condensate water by increasing the efficiency with which moisture contained in the organic sludge is evaporated and the speed at which the organic sludge is dried. An organic sludge drying system (1) is provided with: an organic sludge drying unit (4), wherein the heat source for drying organic sludge (SL) is exhaust gas (G1) at a temperature of 450ºC or less emitted from a waste incinerator (2); a steam condensation unit (8) for condensing steam generated due to the drying performed by the organic sludge drying unit (4); and an incineration ash water-cooled rinsing unit (10) which uses water (W) condensed by the steam condensation unit (8) to rinse incineration ash (A). A decomposer adding unit (7) for adding a substance to decompose proteins contained in the organic sludge (SL) is preferably further provided within or prior to the organic sludge drying unit (4).
