摘要： [Subject] To efficiently reduce lead content of cement without exerting influence upon quality of the cement.
[Means for Solution] The method comprises the steps of: controlling O 2 concentration of combustion gas in an inlet end of a cement kiln to 5 % or lower and/or CO concentration thereof 1000 ppm or more; extracting a part of combustion gas from the cement kiln and collecting dust contained in the combustion gas; and collecting lead from the dust collected. With this, the area where raw material temperature in the cement kiln is between 800°C and 1100°C can be turned into reducing atmosphere to sharply increase volatilization rate of lead, and collection of lead from the dust allows lead content of cement to efficiently be reduced without exerting influence upon quality of the cement. Together with the control described above, where the inner diameter of the cement kiln is D and the distance from the inlet end of the cement kiln longitudinally into the kiln is L, supplying fuel and/or raw material including inflammable material to the area where L/D of the cement kiln is 0 or more and 12 or lower causes securely maintaining the reducing atmosphere of the area.
摘要翻译： [主题]有效降低水泥的铅含量，不影响水泥的质量。 [解决方案]该方法包括以下步骤：将水泥窑入口端的燃烧气体的O 2浓度控制在5％以下和/或其CO浓度为1000ppm以上; 从水泥窑中提取一部分燃烧气体并收集燃烧气体中所含的灰尘; 并从收集的灰尘中收集铅。因此，水泥窑的原料温度在800℃〜1100℃之间的区域可以转化为还原气氛，从而大大提高铅的挥发率，从粉尘中收集铅可以有效地提高水泥的铅含量减少而不影响水泥的质量。连同上述控制，其中水泥窑的内径为D，水泥窑的入口端纵向进入窑的距离为L，向包括易燃材料的燃料和/或原料供应L / D为0以上且12以下的原因可靠地保持该区域的还原气氛。

摘要： Provided is a method of easily and efficiently removing radioactive cesium from a waste contaminated with radioactive cesium. The method of removing radioactive cesium includes a heating step of heating a waste contaminated with radioactive cesium and a CaO source and/or a MgO source at a temperature of from 1,200 to 1,350°C to volatilize the radioactive cesium in the waste. In the heating step, the kinds and the blending ratios of the waste, the CaO source, and the MgO source are set so that the masses of CaO, MgO, and SiO 2 satisfy the equation: (CaO+1.39×MgO)/SiO 2 )=1.0 to 2.5 (in the equation, CaO, MgO, and SiO 2 represent the mass of calcium in terms of an oxide, the mass of magnesium in terms of an oxide, and the mass of silicon in terms of an oxide, respectively).
