Today's industrial processes produce a wide range of noxious chemicals and particulate emissions
which are more suited to ceramic filtration.
Traditional bag filters are unsuitable for the majority of these processes. This is because of their
poor thermal durability and inherent inflammability. Filter bags are also vulnerable to damage
through contact with the cage and abrasion which takes place during reverse pulsing. This also
causes the weave to stretch, which allows submicron particles to enter the media. In turn, this can
cause premature blinding and reduced performance.
To reduce blinding, bag filters need to operate at very low face velocities. They may also require
additional heat exchangers, dilution air, spark arrestors, cyclones and reaction towers to assist
filtration. All of these increase the absorbed power and add to the capital cost of the plant.
The design and materials of
filters avoid these problems very effectively. As well as
outperforming bag filters for many applications,
filters also outperform conventional
ceramic filter media – maintaining their strength at high temperatures while delivering consistent
bulk density and pressure-drop performance.
