Cyclone separator maintenance

  1. 1.  Separators  Types of Dust Separator  Cyclone Separator working & types  Critical Parameters  Advantages  Disadvantages  Applications  maintenance
  2. 2.  PM Inspection  Maintenance of Cyclone Separator  Troubleshooting
  3. 3.  What is Separator ?  What is Dust Separator?  Types of Dust Separator
  4. 4.  A dust separator is an equipment which separates solid particles from fluid mainly a gas
  5. 5.  Inertial or Dry Centrifugals  Wet Collectors (scrubbers)  Fabric Filtration  Electrostatic Precipitators
  6. 6.  Cyclone  Multi tube Cycle  Dry Dynamic
  7. 7.  A cyclone separator is used to separate larger, heavy particles from smaller, lighter particles.  The basic principle of cyclone separators is the action of centrifugal force.
  8. 8.  Tangential inlet  Axial inlet  Scroll inlet
  9. 9.  Gas stream velocity  particle agglomeration characteristics (tendency to join/stick together)  cyclone diameter-to-length ratio
  10. 10.  The collected product remains dry  Low capital investment  Low maintenance cost  Very compact in most applications  Can be used under very extreme processing conditions  No moving parts  Constant Pressure drop  Can be equipped with erosion or corrosion resistant  Can be fabricated with plate metal  Can handle sticky and tacky solids with proper liquid irrigation  Separate liquid or solid particulates, sometime both in combination with proper design.
  11. 11.  A low efficiency for particle sizes below their ‘cut sizes’  Usually higher pressure loss than other separating types, including bag filters, low pressure drop scrubbers , ESPs  Subjected to erosive wear and fouling if solids being processed are abrasive or ‘sticky’
  12. 12.  Oil and gas (for instance in fluidized catalytic cracking unit, FCCU  Power generation  Incineration plant  Iron and steel industry/blast furnaces and non ferrous industries  Food industry  Chemical plants (plastics, elastomers, polymers, etc)  Wood chip, wood mill and building material plants  Sand plants  Cement plants  Cooking plants  Coal fired boiler
  13. 13. There are three general rules  Cleaning the dust-collector storage hoppers at regular, predetermined intervals.  Definite scheduling of inspection for preventive maintenance.  Repairing, replacing, and cleaning all parts where indicated by the regular inspection.
  14. 14. Inspect the separator at periodic maintenance intervals for the following conditions:  Externally for rust, corrosion and peeling paint  Internally for corrosion and accumulations of dirt and oil  Gaskets for damage
  15. 15. Perform the following maintenance tasks.  Remove corrosion and peeling paint.  Prime and paint prepared surfaces.  Thoroughly clean separator internals.  Replace defective gaskets.  Emptying the storage hoppers at regular intervals to avoid re- entrainment.  Avoiding leakage at the dust-discharge point, especially if the unit is under negative pressure.  Routinely inspecting for buildup and extreme wear.  Keeping uniform air volume to maintain constant efficiency
