SFFILTECH high temperature resistant PPS filter bag for coal-fired boilers, waste incinerators
Product Description
The PPS filter bag is made of polyphenylene sulfide raw material. Polyphenylene sulfide, a high-performance thermoplastic engineering plastic, is produced using different production equipment and manufacturing processes based on the characteristics of working conditions and usage requirements. High functional organic polyphenylene sulfide fibers are mixed through needle punching, and then subjected to singeing, heat setting, and rolling to produce PPS needle punched felt with high filtration performance. Then, sew a traditional PPS filter bag using PPS needle felt.
What is a pps filter bag?
PPS filter bags, fabricated from Polyphenylene Sulfide fibers, stand as a premier choice in industrial filtration. These bags, renowned for their thermal resistance and chemical resilience, ensure optimal performance in high-temperature environments. PPS filter bags find indispensable application in dust collection systems, showcasing their effectiveness in particulate matter removal. The exceptional durability of Polyphenylene Sulfide fibers extends the lifespan of PPS filter bags, making them a reliable solution for long-term industrial use. Industrial processes, flue gas treatment, and air pollution control benefit from the superior filtration capabilities of PPS filter bags, contributing to environmental protection. Baghouse filtration systems, designed with PPS filter bags, play a crucial role in maintaining cleaner air quality in diverse industrial sectors. Explore the advanced features and benefits of PPS filter bags for an efficient and sustainable approach to industrial filtration needs
Two factors effect the choice of filter bags
Dust Separation Procedure
Different dust separation procedures require different weights and air permeability values for filter media.
Rules:
- The more effective the cleaning process, the more compact and heavier the filter medium can be.
- The higher the emission control standards, the heavier the filter medium should be.
Tops: If these factors are well considered in advance, running cost like electricity for the fan or pressured-air for the cleaning pulses can be saved later on in a great amount.
