其他信息

  • 类别:氧化剂
  • 方法四:吸收法先将石灰石与白煤按1：(0.11～0.13)的配比间断从石灰窑顶部加入石灰窑中进行煅烧，温度控制在800～1200℃，生成的石灰从窑底间断排出，将其加水消化，得到含有少量游离水的消石灰，陈化8天以上，经绞龙送至风选系统除渣。而粉末状消石灰经旋风分离器进行气固相分离。 含有3％～6％游离水分的细粒消石灰，经消石灰仓下的绞龙从氯化塔的第四层加入，氯气(液氯液化尾气)从氯化塔第一层通入，漂白粉成品由氯化塔第一层排出。其 2Ca(OH)2+2Cl2→Ca(Ocl)2·CaCl2·2H2O 从氯化塔排出的尾气，用液碱吸收后生成次氯酸钠，废气然后放空。
