Abstract
To treat organic sludge while keeping facility costs, cement production efficiency, and a reduction in clinker production amount to a minimum. An organic sludge treatment device includes: a fractionation devicethat fractionates a preheated raw material Rfrom a preheater cycloneC excluding a bottommost cyclone of a cement burning devicea mixing devicethat mixes an organic sludge S with the fractionated preheated raw material, and that dries the organic sludge using sensible heat of the preheated raw material; and a supply device (mixture chutedouble-flap dampershut damper) that supplies a mixture M from the mixing device to a calciner furnaceof the cement burning device or to a duct disposed between a kiln inlet portion of a cement kilnand the calciner furnace. The treatment device may be provided with an introduction device for introducing an exhaust gas Gincluding dust, odor and water vapor from the mixing device to a gas outlet of a bottommost cycloneA of the cement burning device.
