Experimental investigation of the filter media regeneration of differently pleated filter elements

Surface filters are used in various technical processes to separate particles from a particle laden gas. The particles are mainly separated on the surface of the filter medium and on the already formed dsut cake. A main focus in the operation of surface filters lies on particle emission and the stable operation.

Besides flat filter media, folding (pleating) the filter media can be used to increase the filtration area while having the same filter installation size. This method is commonly used to create compact filter systems with a large filter surface area. When using pleated filter media or pleated filter elements (e.g. cartridge filters), certain operational problems occur during operation (e.g. insufficient regeneration, unstable operation), which are mainly attributable to the pleating or the pleating process itself.

To investigate the influence of different filter-media geometries on dust cake formation and regeneration behavior, optical observation of the processes is a suitable approach.

In this work, a peripheral setup for high-time-esolution observation of dust cake buildup and filter media regeneration is to be developed in addition to the existing filter media test rig (in accordance with DIN ISO 11057). Subsequently, the influence of filter media geometry on these two key parameters will be investigated.
