Life Problem Analysis on PPS Filter Application of Bag dedusters in Coal-Fired Power Plants

摘要

In order to control the dust emission for boiler, bag dedusters and composite electrostatic-bag precipitators in the application of coal-fired power plants in China increase annually, these precipitator most on the ratio of higher p-phenylene sulfide (hereinafter referred to as PPS) material produced filter bag, run after period of time, PPS filter bag large appeared the life cycle of damage phenomenon.In this paper, the problems of bag dedusters and composite electrostatic-bag precipitators in the operation are statistically analyzed,especially composite electrostatic-bag precipitators used in the near future will have more appear PPS filter bag oxidation, acid corrosion such problems as the in-depth analysis study, appropriate solutions are presented.
