烟气冷凝再热消白烟技术是利用冷凝和再热原理,通过将烟气中的水分和硫酸等污染物与冷凝水或再热蒸汽进行热交换,使烟气中的水分和硫酸等污染物得以冷凝或转化成固态颗粒物,从而达到消白烟的效果。

其工艺流程一般包括以下几个步骤:

  1. 烟气冷凝:将烟气通过冷凝器,在冷凝器中,烟气中的水分和硫酸等污染物与冷却水进行热交换,使其冷凝成液体或固体颗粒物,从而减少烟气中的水分和硫酸等污染物含量。

  2. 除尘:将冷凝后的烟气进入电除尘器,通过电场作用将其中的粉尘、烟尘等固体颗粒物去除。

  3. 再热:将除尘后的烟气通过再热器,与再热蒸汽进行热交换,使烟气中的水分和硫酸等污染物得以蒸发或转化成固态颗粒物,从而达到消白烟的效果。

  4. 排放:经过烟气冷凝、除尘和再热等处理后,烟气中的污染物浓度得到降低,达到国家环保标准后再进行排放。
