Description

卡尔多炉焚烧电/线路板烟气净化方法
技术领域
本发明涉及卡尔多炉生产技术领域，尤其涉及卡尔多炉焚烧电/线路板烟气净化方法。
背景技术
目前，电/线路板的焚烧及绝大部分冶金企业烟气因条件所限制，并未进行特殊净化、处理，有个别良好企业仅是通过二噁英二次焚烧等方式做简单处理。故排出的烟气中酸性气体的含量严重超标，特别是二噁英含量超出国家规定达标含量的数倍、甚至数百倍，造成了严重的大气污染。因此，很多企业因烟气排放不达标而受到政府罚款，有严重者甚至导致被迫停产。
发明内容
本发明所要解决的技术问题是提供一种高效率的卡尔多炉焚烧电/线路板烟气净化方法。
为解决上述问题，本发明所述的卡尔多炉焚烧电/线路板烟气净化方法，包括以下步骤：
⑴卡尔多炉焚烧电/线路板产生的烟气进入卡尔多炉焚烧电/线路板烟气净化烟道，然后经余热锅炉换热后，此时烟气温度降低至150℃~250℃；
⑵所述步骤⑴所得的降温后的烟气依次进入动力波洗涤器Ⅰ、动力波洗涤器Ⅱ，并分别用碱液进行两级酸性气体吸收除尘，得到除尘后的烟气；
⑶所述除尘后的烟气经干燥塔干燥后，进入活性炭吸附塔除去二噁英类物质及残留溴，然后经烟囱排空即可。
所述步骤⑴中的卡尔多炉焚烧电/线路板烟气净化烟道，包括与卡尔多炉相连的烟道；所述烟道末端连有烟囱；所述烟道上按先后顺序依次连有余热锅炉、动力波洗涤器Ⅰ、动力波洗涤器Ⅱ、干燥塔、活性炭吸附塔。
所述步骤⑵动力波洗涤器Ⅰ中的碱液是指浓度为0.05g/L~0.15 g/L的氢氧化钠溶液。
所述步骤⑵动力波洗涤器Ⅱ中的碱液是指浓度为0.5g/L~1.5g/L的氢氧化钠溶液。
本发明与现有技术相比具有以下优点：
本发明将烟气通入余热锅炉换热，将温度从1100℃~1250℃极速降低到150℃~250℃，从源头减少了二噁英的产生量（塑料焚烧中二噁英产生的温度一般为400℃~600℃）；后又通过动力波洗涤器将烟气进行两级酸性气体吸收、除尘；最后经干燥塔干燥后，进入活性炭吸附塔，除去剩余二噁英类物质及残留溴，不但效率高，而且有效净化烟气，使排除的气体中二噁英含量100%达到国家规定标准（国家标准0.1ng TEQ/Nm3即欧盟标准)。
附图说明
下面结合附图对本发明的具体实施方式作进一步详细的说明。
图1为本发明的结构示意图。
