    • A treatment system to efficiently remove lead from dust contained in extracted cement kiln combustion gas while reducing facility and running costs. A treatment system 1 comprising a probe 3 for extracting a part of combustion gas, while cooling it, from a kiln exhaust gas passage, which runs from an inlet end of a cement kiln to a bottom cyclone; a first classifier 5 for separating coarse powder from dust contained in the combustion gas extracted; a dust collector 7 for collecting dust from the extracted gas containing fine powder discharged from the first classifier 5; and a second classifier 8 for dividing dust discharged from the dust collector 7 into fine powder and coarse powder, and others. Since more lead is distributed on the fine powder side classified by the second classifier 8, lead can efficiently be removed without using chemicals and the like. The fine powder classified by the classifier 8 may be desalted by washing; high-lead-level cake obtained after the washing can be recycled; or salt water can be added to a cement mill. The coarse powder may be added to a cement grinding process or returned to cement material grinding process after the desaltation through washing.
    • 一种处理系统,可有效去除提取的水泥窑燃烧气体中含有的灰尘,同时降低设备和运行成本。 一种处理系统1,其包括用于从其从水泥窑的入口端延伸到底部旋风器的窑尾废气通道在冷却时提取一部分燃烧气体的探针3; 用于将粗粉与从所提取的燃烧气体中所含的灰尘分离的第一分级器5; 用于从包含从第一分级器5排出的细粉末的提取气体中收集灰尘的集尘器7; 以及用于将从集尘器7排出的粉尘分解成细粉末和粗粉末的第二分级器8等。 由于在由第二分级器8分类的细粉末侧分布更多的铅,因此可以在不使用化学物质等的情况下有效地除去铅。 由分级机8分类的细粉可以通过洗涤脱盐; 洗涤后获得的高铅级蛋糕可以回收利用; 或盐水可以添加到水泥磨。 可以将粗粉末加入水泥研磨过程中,或通过洗涤脱盐后返回水泥材料研磨过程。
