LP Panelized Baghouse 684LP - 882LP
Electrical work during installation, service or maintenance must be performed by a qualified electrician and comply
with all applicable national and local codes.
Turn power off and lock out all power before performing service or maintenance work.
Turn compressed air supply off, bleed and lock out lines before performing service or maintenance work.
Check that the collector is clear and free of all debris before starting.
Do not install in classified hazardous atmospheres without an enclosure rated for the application.
During normal operation, dust-laden air enters the dirty-air inlet. The tangential inlet with helix develops a cyclonic airflow causing
heavier particulate to drop directly into the hopper. The air continues through an internal flow straightener that evenly distributes
the dust-laden air within the collector cross-section and around the filter bags. After entering the collector the light dust collects on
the outside surface of each filter bag forming a dust cake. Clean, filtered air passes through the filter bags to the clean-air plenum
and discharges through the clean-air outlet.
3 Operation
Typical Collector Start-Up/Shut-Down Sequence
Start-Up
1. Start material discharge mechanism such as a rotary airlock (if applicable).
2. Start gear box motor for cleaning arm rotation.
3. Start reverse-air cleaning assembly fan.
4. Start main system fan.
5. Start process equipment.
Shut-Down
1. Stop process equipment. Allow main system fan and LP to continue operating for 10-15 minutes to clear dust from conveying
ducts.
2. Stop main system fan. Allow LP reverse-air fan and gear box motor to continue running for 5-10 minutes for a brief period of
enhanced filter bag cleaning.
3. Stop LP reverse-air fan and gear box motor. Allow material discharge mechanisms to run for 10-15 minutes after reverse-air
fan and gear box motor shut off to ensure dust is fully evacuated from the hopper of the LP.
4. Stop material discharge mechanism.
Reverse Air Internal Cleaning System
The cleaning system contains an internal fan with reverse air flow design. The sweep arms have a flow-stop plate which keeps air
from flowing through the bag filters before and after cleaning. This feature reduces the chances of dust from cleaned bags being
re-entrained onto recently cleaned bags, resulting in lower pressure drop and reduced energy costs due to bags staying cleaner
longer. The system does not require any compressed air supply.
