摘要(Abstract)：

湿法脱硫吸收塔对从除尘器逃逸的细小粉尘具有一定脱除作用,但其具体除尘机理与除尘效率有待深入研究。对此,以典型湿法脱硫工艺中的吸收塔为研究对象,搭建模拟试验台针对脱硫系统运行参数(塔内烟气流速、入口粉尘质量浓度等)及吸收塔内主要部件布置形式对粉尘颗粒物脱除效果进行冷态试验。结果表明:烟气流速和入口粉尘质量浓度均对除尘效率存在影响,除尘效率与烟气流速呈反比,与入口粉尘浓度呈正比;喷淋层作为吸收塔内主要部件,其布置形式和运行工况对吸收塔除尘效率存在较大影响,开启5层喷淋层除尘效率接近100%;托盘对除尘效率影响由其安装高度和喷淋层运行情况决定,安装高度越高除尘效率越低。
