摘要(Abstract)：

基于石灰石-石膏湿法烟气脱硫(WFGD)工艺,通过数值计算获得脱硫塔进口烟气温湿度对塔内过饱和水汽环境的影响规律,并试验考察了塔入口烟气参数及脱硫操作条件对SO_3酸雾脱除特性的影响。结果表明,通过调节脱硫塔入口烟气温湿度可使塔内形成SO_3酸雾凝结长大所需的过饱和水汽环境,适当降低塔入口烟温或提高塔入口烟气湿度可有效提高WFGD系统对SO_3酸雾的脱除效果,脱除效率可从40%增至60%左右;同时,适当提高脱硫液气比及降低浆液温度有利于促进SO_3酸雾的脱除,脱除效率可提高10%左右。

关键词(KeyWords)： 石灰石-石膏法脱硫;SO3酸雾;水汽相变;脱除
