2019-07-21 16:21:47

随着大气污染防治工作的推进,环保要求日益严格,污染物减排的政策不断推出,标准也不断提高。2015年底《全面实施燃煤电厂超低排放和节能改造工作方案》实施,要求所有具备改造条件的燃煤电厂力争实现超低排放(在基准氧含量6%条件下,烟尘、SO2,NOx排放浓度分别不高于lOmg/m³35mg/m³,50mg/m³。标准愈发严格,对现有燃煤锅炉提效改造及新建燃煤锅炉实现超低排放提出了新要求。

过滤除尘是指含尘烟气通过滤料将尘粒捕集分离,除尘效率较高。布袋除尘器是其中较常用且的除尘方法,除尘率可以达到99.9%。除尘布袋多使用无纺布、针刺毡等材料做成,可对烟气中的细微颗粒粉尘进行过滤。目前市场已有可以达到超低排放标准的布袋。其缺点是不耐高温,易受腐蚀、水汽等影响,这使其适用范围与便捷性受到限制。
