Characterization of long-term filtration behavior of textile dust filtering media

摘要

Increasing technical requirements, linked with a consequent increase of environmental protection legislation, have led to a considerable improvement of particle separation from gases. On account of its significance for air quality, in particular on account of the lung deposition, the relatively long stay time in the terrestrial atmosphere and the adsorptive enrichment of substances, which pose a health risk, particular importance must be attached during the emission of dust to the growing fine dust proportion (particle size < 5 μm). Filtering separators count among the preferential dust separation techniques for fine dust. Their constantly rising market penetration is, last but not least, due to the filter media that permit a comparatively sure separation of fine dust. Among the filtering separators, cleaning filters serve for the separation of particles of gases with high dust contents of some g/m~3.
