布袋滤料的选择标准

             来源:厦门恒绿环保工业有限公司 阅读:1712 更新时间:2008-08-13 16:59

滤料的选择标准 choice condition of filter medium

• 烟气的性质和温度 Soot property and temperature

• 粉尘的性质、浓度和成份 Dust property, thickness and component

• 清灰原理 Dust clearance method

其他用于选择过滤材料的标准必须服从于排放浓度的控制标准和使用寿命的要求。
Of course, whatever filter medium, we need to make sure to meet exhaust thickness and lifetime requirement.

以下的表格可以作为一个滤料材质的选择指南。 Please find the below filter medium choice instruction.
