摘　　要：除尘设备从最初的重力式、惯性式、离心式、清洗式发展到过滤式和静电式。现代水泥工业中,静电除尘器和布袋除尘器得到了极大的发展。静电除尘器始终未能克服其自诞生之日起存在的缺陷。布袋除尘器因为聚四氟乙烯覆膜技术的发明而越来越受到水泥企业的青睐,但诸多工艺因素诸如结露、废气温度、过滤风速、风压等都影响着布袋除尘器的可靠性。De-dusting equipment have developed from original gravity type, inertia type, centrifugal type and cleaning type to filtration type and electrostatic type. In modern cement industry, electrostatic precipitators and bag filters have developed extensively. Till now, electrostatic precipitators have not overcome existing disadvantages since their birthday. Although bag filters are welcome broadly because of the invention of Teflon filming technique, a lot of process factors like dewing, high waste gas temperature, filtering gas speed and pressure etc. have influence on the reliability of bag filter.
