Collector Operation
Operation
During normal operation, dust-laden air enters the
collector through the dirty-air inlet, which is positioned
over the venturi section of the dirty air plenum. Airflow
is directed downward through the collector over the
venturis and heavier particulate falls directly into the
hopper. The filters remove fine particulate allowing
filtered air to pass through the filters to the clean-air
plenum where it discharges through the clean-air outlet.
Filter cleaning is completed using pulse-jet technology.
A solenoid and diaphragm valve aligned to each row
of filters provides the pulse cleaning. The cleaning
sequence starts at the top filter row and continues down
through the module. Removal, inspection, or replacement
of filters can be accomplished from outside the collector
by removing the filter access cover and sliding the filters
out.
