START-UP DUST CONTROL SYSTEMS
1. Fan or blower system
A. Start the fan or blower and check rotation.
B. Check dust pickup points for proper suction; balance airflow in individual
ducts.
C. Check for air leakage at all flanged connections.
2. Equipment start-up sequence
A. Start the sweep arm drive motor. The sweep arm should rotate CCW when
viewed from above. An arrow noting the rotation direction is located on the
vertical air pipe.
B. Start the reverse air fan motor and check for CW rotation of the wheel (as
viewed from the motor side of the fan or CCW as viewed from the fan inlet).
This is CRITICAL to the proper cleaning of the bags. Air will exit the
nozzles regardless of direction, but will not be sufficient to clean unless the
fan wheel is rotating the correct direction.
C. Dust take away equipment such as rotary airlocks, screw conveyors,
horizontal unloading valves, live bottom bin activators, and pneumatic
conveying systems can now be started in their correct sequence.
D. Check that all access doors, hatches, ports, and other openings are closed and
latched or bolted.
E. The main exhaust fan can now be started and brought up to speed.
F. Start the dust laden air through the collector. The collector should be started
under partial load to allow the bags to become slowly and evenly coated with
dust particles.
On pneumatic conveying systems, watch the differential pressure gauge
closely for the first hour or so. If unstable, the collector discharge system
may be too small for the volume it is seeing. A quick fix is to reduce the
material feed until the discharge rate can be increased.
