摘　　要：针对铝用预焙阳极焙烧排放烟气成分比较复杂(含有SO2、NOx、CO、颗粒物、焦油、氟化物等物质),某公司原有铝用预焙阳极焙烧烟气净化系统已不能满足现阶段生产环保需求的现状,选择应用循环流化床干法烟气脱硫技术对传统的"超净+排放"湿法脱硫技术进行了优化,应用实践表明,该技术取得了超过预期的良好效果并实现超低排放。In view of the complexity of flue gas emission from aluminum pre-baked anode baking furnace,involving SO2,NOx,CO,particles,tar,fluoride and other substances,the original pre-baked anode baking flue gas purification system for aluminum in a company can no longer meet the current production environmental protection needs.The traditional wet"super net discharge"desulfurization technology has been optimized by using circulating fluidized bed dry flue gas desulfurization technology.The technology has achieved better expected results and ultra-low emissions.
