摘　　要：将凝变技术与湿式电除尘器技术进行有机结合,集成凝变湿电复合烟气污染物协同控制技术,研究该技术对2μm以下可过滤性颗粒物和可凝结颗粒物的团聚、凝并、收集效果。凝变湿电复合烟气污染物协同控制技术在630 MW大型燃煤机组上的工程应用结果表明,该复合技术可显著提高烟气中微细颗粒物的脱除,使机组稳定实现颗粒物排放小于5 mg/m3;脱除烟气中70%以上的可溶性盐分,实现烟气污染物的协同控制;降温2℃,每小时回收15 t的水,可减缓烟囱"白烟"现象。A synergistic control technology of flue gas pollutants was obtained by combining condensation technology and WESP,to study the reunion,coagulation and collection effects of this technology on filterable and condensable particles below 2 μm. The synergistic control technology was applied in a 630 MW large-scale coal-fired unit. Results showed that this technology could significantly improve the removal efficiency of fine particles in flue gas,to make particulate matters discharged from the chimney of the unit less than 5 mg/m3. More than 70% of the soluble salt in the flue gas was removed,to achieve synergistic control of flue gas pollutants. About 15 tons of water was recovered per hour when the flue gas was cooled 2 ℃,and the ＂white smoke＂could be slowed down.
