Polytetrafluoroethylene (PTFE) dust removal bags have been widely used in the dust removal of high-temperature flue gas due to their excellent high-temperature resistance and chemical stability. Its service life is influenced by various factors, such as smoke temperature, smoke composition, filtration speed, humidity, etc.
Under suitable conditions, the service life of polytetrafluoroethylene dust removal bags can reach several years, but if encountering harsh environments such as high temperature and acid alkali corrosion, the service life may be greatly shortened. Therefore, when selecting polytetrafluoroethylene dust removal bags, it is necessary to choose appropriate materials and specifications based on specific working conditions, and strictly follow the operating instructions and maintenance requirements to operate and maintain the equipment, in order to extend the service life of the dust removal bags.
