Cleanable bag filter : comparisons of different testing methods of ageing of filter materials

  • Cleanable bag filters are used to separate dust and other airborne particulate systems. Due to typical process conditions, they are subject to thermal, chemical and mechanical stress during use. The main objective of the IGF project no. 18307 "Investigation of the chemical and thermal degradation of cleanable filter media and improvement of their resistance by surface modification", was the development of a valid test method which can reproduce degradation caused by high temperatures and aggressive chemical atmospheres in a practice-oriented but time-saving manner. Within the IGF project, 2 accelerated ageing methods were applied, both of which have the decisive advantage of investigating damage in the gas phase. Many resistances of filter materials are otherwise carried out by immersing the materials in a mostly liquid damage medium at a defined temperature. These resistances are difficult to transfer ageing in the gas phase.
