 The service life of the bag filter bag is affected by multiple factors such as material, working conditions, and maintenance, and is usually 1-5 years. Specifically: Material: Polyester bags are about 1-3 years old, PPS bags are 3-5 years old, and PTFE bags can last for more than 5 years. Working conditions: High temperature (>160 ℃), high dust concentration, and high abrasive dust will accelerate aging, and low temperature condensation will also shorten the service life. Maintenance: Regular inspection, cleaning, and pre coating can extend the service life by 30% -50%. Case: A certain steel enterprise adopts PTFE+fiberglass composite cloth bags, which have a service life of over 3 years under the working condition of 190 ℃. Suitable materials should be selected according to the specific environment, operating parameters should be optimized, and daily maintenance should be strengthened to extend the lifespan. |
