In terms of particle removal from gases with surface filters, the periodic building and detachment of particle layers decisively determine the operating behaviour and the performance of the filter. Besides the particular type of detachment force the quality of regeneration mainly depends on the interaction between the particle layer and the surface of the filter medium (adhesion), and the strength of the particle layer structure itself (cohesion). The local distribution and strength of adhesion forces results from the structure of the filter cake on the filter medium. In this context, the surface structure including the near-surface, porous transition area between the filter cake and the filter medium is of fundamental importance. Finishes are used to systematically improve the operating behaviour of textile filter media by modifying the surface texture. As a result, a vast number of different structures is available.
Main aim of the research project is to experimentally and theoretically investigate the operating performance of differently structured needle felts....
