WIPO Patent Application WO/2019/193938

Kind Code:

A1

Abstract:

[Problem] To treat organic sludge while keeping facility costs, cement production efficiency, and a reduction in clinker production amount to a minimum. [Solution] An organic sludge treatment device comprises: a fractionation device 7 that fractionates a preheated raw material R2 from a preheater cyclone 4C excluding a bottommost cyclone of a cement firing device 1; a mixing device 8 that 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 chute 12, double-flap damper 13, shut damper 14) that supplies a mixture M from the mixing device to a pre-calcinating furnace 5 of the cement firing device or to a duct disposed between a kiln tail portion of a cement kiln 2 and the pre-calcinating furnace. The treatment device may be provided with an introduction device that introduces an exhaust gas G2 including dust, odor, and water vapor from the mixing device to a gas outlet of a bottommost cyclone 4A of the cement firing device.
