1.除尘器收尘排放及工艺系统的稳定由于烟气状况(如含尘浓度、风量、温度及成分等)发生变化，对袋除尘器收尘效率影响不大，加上袋除尘器可以在使用中分室维修，而电除尘器则不然。因此，环保要求严格地区及运转率高的烘干机宜使用袋除尘器。电除尘器排气阻力小(一般200pa)而且稳定，对烘干机工作影响很小，而袋除尘器排风阻力大而且清灰前后阻力波动大，对
烘干机工作有一定的影响，在糊袋或掉袋时，主机不能正常运行。因此，工艺系统工作稳定要求很高时，宜使用电除尘器。2.投资烘干机在水泥厂一般属于中等排风量的设备，在同等工况条件下，一般认为，烘干机风量较小时，使用袋除尘器投资较少，对于风量较大的烘干机，两种除尘器的投资关系不大。一般来说，袋除尘器设备费用略低于电除尘器，运输费较低、安装量较小、维护费用较高(主要是更换滤袋)；袋除尘器阻力大，主风机和清灰消耗较大的能源，电除尘器主机耗能较小，但电场耗电加上振打及电加热装置耗电，能耗很接近。3.操作人员要求除尘器的运行多采用程序控制，操作都很简单，袋除尘器根据进出口差压调整清灰周期，而电除尘器根据极板积灰厚度调整振打周期。相比之下，在维护保养时，对使用电除尘器的操作人员要求较高。在电除尘器上采用高电压和较多的机械转动装置，操作人员须懂得电工和机械基本常识；而使用袋除尘器维护工作劳动条件差、强度较高。
The comparison of electrostatic precipitators and bag filter dryer equipment 1. Precipitator dust emission and the stability of the process system because of the flue gas condition (such as dust concentration, air velocity, temperature and composition, etc.) change, the impact is not big on bag filter dust collecting efficiency, combined with bag filter can be used in the chamber in the maintenance, the electric dust collector is not. Therefore, the strict environmental protection area and high rates of operation of the dryer appropriate use of bag filter. Small exhaust resistance (200 pa) electrostatic precipitators and stable, little impact on the dryer work, and large bag filter exhaust resistance and resistance volatility before and after the dust, has certain influence to the dryer work, when paste bag or off bag, the host can't normal operation. Therefore, high requirement of technology system work stable, appropriate use of electric dust collector. 2. Investment in cement plants generally belongs to the medium of the exhaust air dryer equipment, under the same working condition, it is generally believed that the dryer air volume is small, the use of bag filter with less investment, with air volume is
