During normal operation, dust-laden air is drawn to the
filter bags. The velocity is reduced and natural pre-
separation, caused by the effects of gravity, takes place.
Fine particles collect on the outside surface of the filter
bag and clean, filtered air passes to the center of the bag
and discharges through the clean-air outlet.
Filter cleaning is completed using pulse-jet technology. A
jet tube positioned over each filter bag distributes a pulse
of compressed air through the filter. As the compressed
air enters the filter bag, airflow is temporarily reversed
and the bag inflates dislodging the dust cake formed on
the outside of the bag. The bag deflates and the dust
cake falls back into the silo or process equipment.
