燃煤电厂电-袋复合除尘器滤袋损坏原因分析

Filtering Bag Breakage Analysis on Composite Electrostatic-bag Precipitator in Coal-Fired Power Plants

着重对电-袋复合除尘器存在的PPS滤袋短期内出现非寿命期大面积损坏的原因,以及针对电-袋复合除尘工艺技术中的部分不同意见,进行了进一步的分析和探讨;提出电-袋复合除尘器与袋式除尘器在技术经济上并没有特殊优势,且电-袋复合除尘器在应用中已发现了一些重大问题,因而应引起有关重视,在选择采用这种工艺技术时要慎重。

The paper analyzes and probes into the breakage reasons of PPS filtering bags existed in the electric-bag composite precipitator within the short period of time and the different opinions on technology of electric-bag composite precipitator, puts forward that there are no special advantages for electric-bag composite precipitator and bag precipitator in technical and economic fields.Some of major problems are shown in the application of electric-bag composite precipitator so that we should be careful when we select this technology.
