    摘要: Method and system for a cement burning facility. When exhaust gas in a part of a preheater or a kiln inlet of a cement kiln is extracted, a cement material is dispersed. The dispersed amount of the cement material is adjusted to maintain the temperature of the extracted gas between 950° C. and 1,150° C. The extracted gas is cooled to at most the melting point of a chlorine compound. A solid-gas separation device adjusts classification particle size to between 15 μm and 30 μm. A dust trap removes fine powder dust with a particle size equal to or smaller than the classification particle size. The amount of fine powder dust collected by the dust trap is maintained between 50 g/m3N and 150 g/m3N, with the concentration of chlorine in the collected fine powder dust set to between 5% and 20%.

    摘要: An object of this invention is to provide an exhaust gas treatment method and system for a cement burning facility which allows the handling property of collected powder dust to be improved and which enables smooth removal of hydrogen chloride that may result from burning of organic sludge. When part of exhaust gas in a lowermost part of a preheater 3 or a kiln inlet part 2 of a cement kiln 1 is extracted to obtain extracted gas, a cement material is dispersed, and the disperse amount of the cement material is adjusted so as to maintain the temperature of the extracted gas between 950° C. and 1,150° C. The extracted gas is cooled to at most the melting point of a chlorine compound. Then, solid-gas separation device 12 adjusts a classification particle size to between 15 μm and 30 μm. Dust trap 13 collects and removes fine powder dust with a particle size equal to or smaller than the classification particle size. Thus, the amount of fine powder dust collected by the dust trap is maintained between 50 g/m3N and 150 g/m3N, with the concentration of chlorine in the collected fine powder dust set to between 5% and 20%.
