摘要：The polyphenylene sulfide (PPS) filter bags of some electrostatic bag composite precipitators are prone to being damaged within 4-12 months. In this work, to study the degradation mechanisms of the PPS filter material used in electrostatic-bag precipitators, we simulated the working environment of the precipitator. Additionally, after the aging corrosion, we analyzed the mechanical properties, morphology, crystallinity, and chemical elemental composition of the PPS filter material, along with the components of flue gas in the precipitator. The results showed that oxidizing agents (O-3, NO2, and SO3) can be produced in the process of corona discharge of the flue gas and that they accelerate the crystallization and the degradation of crystalline and amorphous regions of the PPS, leading to the degradation of PPS in the electrostatic-bag precipitator. With the coexistence of NO2 and SO3, the degradation energy barrier of PPS was reduced, thus resulting in faster degradation.
