宝钢电厂3号机组电除尘器改布袋除尘器滤料选用探析倪建东上海宝钢工程技术有限公司
摘 要:为实现低粉尘排放浓度来改善大气环境质量,近年来电厂燃煤机组掀起了电除尘器改造成为布袋除尘器(简称"电改袋")的热潮。电改袋成败与否的核心因素之一就是滤料的选择正确与否。通过一系列实测数据并结合理论分析,介绍了宝钢电厂3号机组电改袋工程的背景和布袋运行所处的特定工况条件;分析对比了几种可供选择的滤料,着重分析并阐述了选用聚四氟乙烯(PTFE)基布/聚苯硫醚(PPS)超细面层滤料的原因及其结构形式、性能和应用效果。实际运行效果证明采用超细面层滤料实现低浓度排放的可行性,展望了该种滤料在电厂燃煤锅炉除尘上的应用前景。
