Description

一种水泥除尘系统 技术领域
本发明涉及水泥除尘装置应用技术领域，具体为一种水泥除尘系统。

水泥工业是我国工业排尘的主要来源，粉尘排放量约为其产量的2％～3％，全国的排放总量超过千万吨，人体长期接触水泥粉尘易引起各种疾病，水泥粉尘会造成土地碱化，严重污染环境，水泥生产工艺过程中，无论是破碎、烘干还是粉磨，煅烧都会产生大量的粉尘，由于各道工序都是干操作业，因此形成了扬尘点多、面大、范围广的特点，而水泥窑尾窑头废气量约占整个水泥生产线废气量的60％，其中窑尾废气约占整个水泥生产线废气量的36％了。
对比文件1：中国专利CN202921115U描述了一种水泥粉尘清除机构，包括风箱、除尘管道、水雾喷头和驱动电机，所述除尘管道连接在风箱背部，所述驱动电机安装在风箱一侧，所述风箱的顶部设置有进风管，在风箱的一侧安装有水雾喷头，在风箱的底部开设有排水口，所述风箱的中心部位安装有连动转轴，在连动转轴上安装有扇叶，连动转轴的一端设置在风箱的外部，并通过皮带连接在驱动电机上，所述风箱的上部为圆弧形结构，所述进气管的顶部设置有顶盖，所述机构存在许多不足，如风箱上设置了太多的结构使此机构使用寿命变短，承受压力小，工作效率低等缺点。目前的水泥除尘装置窑尾废气温度高、烟气量大，比较难清理，石灰厂的粉尘处理旋风除尘器存在不足，因此，针对上述问题提出一种水泥除尘系统。
