Methods to increase the filtration performance of metal woven wire cloths

M. Müller*, Spörl KG, Germany

With their narrow pore size distribution metal woven wire cloths guarantee an excellent separation and classifying accuracy. Due to their high chemical, thermal and mechanical resistance, wire meshes as metallic filter media can be used in demanding operation conditions, for example in the form of high process pressures and temperatures or sharp-edges particles which have to be deposited. Depending on the combination of the warp wires and the weft wires during the weaving process, the production of different types of weave with different aperture sizes and filtration behaviors is possible. The filtration performance can be assessed based on the initial pressure loss, absolute pore size, dirt holding capacity, load-depending separation efficiency and cleaning behavior. In the paper, these parameters are determined experimentally using a flow rate test-rig, an air-solid test-rig and a cleaning test-rig based on DIN ISO 11057. The performed experimental investigations show, that...
