PPS bags are made primarily from Polyphenylene Sulfide (PPS) fibers and are manufactured through processes like three-dimensional needle-punching, resulting in a high-performance dust collector bag with the following outstanding features:
Excellent high-temperature performance
Continuous operating temperature typically reaches 160°C, with instantaneous temperature resistance up to 190°C, suitable for coal-fired boilers, garbage incineration, and other medium and high-temperature flue gas environments.
2. High resistance to chemical corrosion
Excellent stability against corrosive gases such as sulfur oxides (SOx, SO2), acids, and alkalis, commonly used in power plant desulfurization, chemical industry, metallurgy, and other sectors.
3. High filtration efficiency
Fibrous structure is dense, with a surface suitable for coating treatment, achieving a filtration accuracy of over 99.99%, suitable for *** emission requirements.
High mechanical strength and good dimensional stability
Maintains structural integrity in high-speed airflow and dust erosion environments, is not prone to deformation or damage.
5. Easy-to-clean, long-lasting
Smooth surface, excellent dust shedding properties; when used with the pulse cleaning system, it can extend the service life to over 3 years.
6. Optional composite form
PPS+PTFE composite filter bags, further enhancing oxidation resistance, water resistance, and anti-dew condensation properties, suitable for more complex operating conditions.
In summary,PPS bags are an ideal dust removal material for high-temperature, high-corrosion, and high-filtration accuracy conditions, widely used in industries such as power, steel, cement, and waste incineration.
When selecting laminated PPS filter bags, consider the following factors:
Process Conditions: Including temperature, humidity, dust characteristics, etc., to ensure the filter bag material is compatible.
(2) Filtration Precision: Select an appropriate membrane aperture based on emission standards.
(3) Lifespan: Choose products with better durability while ensuring effective filtration.
To extend the service life of the coated PPS filter bags, the following measures are recommended: (1) Regular inspection: Observe for any signs of damage or clogging in the filter bags. (2) Proper dust removal: Use an appropriate dust removal method (such as pulse jetting) to avoid over-cleaning that may damage the coating. (3) Avoid over-temperature operation: Prolonged operation above the filter bag's tolerance temperature accelerates aging.
