PPS 滤袋正常使用周期大概多久？

Polyphenylene sulfide (PPS) filter bags are core components of industrial dust collection systems, deployed across coal-fired power plants, cement production lines, municipal waste incinerators, and metal processing facilities, valued for their balance of chemical resistance and thermal stability. The normal service cycle of PPS filter bags is not a fixed value, but a range shaped by material properties and operational conditions, with clear benchmarks that guide industry maintenance schedules.Typically, standard untreated PPS filter bags, unmodified with surface treatments, have a normal service cycle of 12 to 24 months. This applies to moderate-use environments where flue gas temperatures stay within PPS’s continuous operating range of 130–160°C, acidic gas concentrations (SO₂, NOₓ) are low to medium, and dust is minimally abrasive. For instance, small to mid-sized coal-fired boilers with well-controlled flue gas chemistry often see untreated PPS bags operate relia...
