Baghouse Dust Collector Periodic Inspections
Daily
Walk through the baghouse area to check for normal or abnormal visual and audible conditions.
Check the pressure drop.
Monitor the gas flow rate.
Check the cleaning cycle.
Check compressed air and water traps on pulse jet baghouses.
Monitor the discharge system by making sure dust is removed as needed.
Observe the stack plume opacity.
Weekly
Spot check bag seating conditions.
Spot check for bag leaks and holes.
Check all moving parts on shaker baghouses.
Check fans for corrosion and blade wear.
Check all hoses and clamps.
Inspect the baghouse housing for corrosion.
Monthly
Spot-check bag tensioning in reverse air and shaker baghouses.
Blow out (clear) the manometer or magnehelic lines.
Verify the working order of temperature-indicating equipment.
Check the compressed air lines, including line oilers and filters.
Check the bag cleaning sequence to see that all valves are seating properly.
Check all moving parts on the discharge system and check the screw conveyor bearings.
Check the drive components on all fans.
Quarterly
Thoroughly inspect all filter bags.
Calibrate the opacity monitor.
Check gaskets on all doors and ducts.
Inspect the paint on the baghouse and note corrosion.
Inspect the baffle plate for wear.
Observe the dampers for proper seating.
Check the ducts for dust buildup.
Annually
Check all welds and bolts.
Check the hoppers for wear.
Replace high-wear parts on the cleaning system.
Wet Scrubber Periodic Inspections
Daily
Check recycle flow.
Check bleed flow.
Measure temperature rise across motor.
Check fan and pump bearings every 8 hours for oil level, oil color, oil temperature, and vibration.
Check scrubber pressure drop.
Check pump discharge pressure.
Check fan inlet and outlet pressure.
Check slurry bleed concentration.
Check vibration of fan for buildup or bleeds.
Record inlet and saturation temperature of gas stream.
Use motor current readings to detect flow decreases. Use fan current to indicate gas flow.
Weekly
Check wet/dry line areas for material buildup. Clean, if necessary.
Check liquid spray quantity and manifold pressure on mist eliminator automatic wash down.
Inspect fans on dirty applications for corrosion, abrasion, and particulate buildup.
Check bearings, drive mechanisms, temperature rise, sprocket alignment, sprocket wear, chain tension, oil level, and clarifier rakes.
Check ductwork for leakage and excessive flexing, Line or replace as necessary.
Clean and dry pneumatic lines associated with monitoring instrumentation.
Semiannually
Verify accuracy of instruments and calibrate.
Inspect orifice plates.
Clean electrical equipment, including contacts, transformer insulation, and cooling fans.
Check and repair wear zones in scrubbers, valves, piping, and ductwork.
Lubricate damper drive mechanisms and bearings.
Verify proper operation of dampers and inspect for leakage.
