    摘要: An exhaust gas treatment method and system of a cement burning facility, wherein a chlorine concentration of the collected fine powder dust is set in a range of 5 to 20% in such a manner that when a part of exhaust gas is extracted as extracted gas from a lowermost part of a preheater, or a kiln inlet part of a cement kiln, a cement raw material is dispersed and the temperature of the extracted gas is held in a range of 950° to 1150° C. By adjusting the dispersion amount of the cement raw material, the extracted gas is cooled to a melting point or less of a chlorine compound, and a classification particle size in a solid-gas separator is then adjusted in a range of 12 μm to 30 μm, to separate for removal and collection fine powder dust.

    摘要: An object of the present invention is to provide an exhaust gas treatment method and system of a cement burning facility which can be configured by general-purpose apparatuses, and which is capable of improving the handling property of collected fine powder dust and thereby realizing a stable operation without the need of maintenance. To this end, according to the present invention, the chlorine concentration of the collected fine powder dust is set in a range of 5 to 20% in such a manner that when a part of exhaust gas is extracted as extracted gas from a lowermost part of a preheater 3, or a kiln inlet part 2 of a cement kiln 1, a cement raw material is dispersed and the temperature of the extracted gas is held in a range of 950° C. to 1150° C. by adjusting the dispersion amount of the cement raw material, that after the extracted gas is cooled to a melting point or less of a chlorine compound, a classification particle size in solid-gas separation means 12 is adjusted in a range of 12 μm to 30 μm, to separate dust having the classification particle size or more, and that fine powder dust having the classification particle size or less is collected and removed from the extracted gas by dust trap means 13.
