4. What is Separator ? What is Dust Separator? Types of Dust Separator

5. A dust separator is an equipment which separates solid particles from fluid mainly a gas

6. Inertial or Dry Centrifugals Wet Collectors (scrubbers) Fabric Filtration Electrostatic Precipitators

7. Cyclone Multi tube Cycle Dry Dynamic

8. 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.

10. Tangential inlet Axial inlet Scroll inlet

14. Gas stream velocity particle agglomeration characteristics (tendency to join/stick together) cyclone diameter-to-length ratio

15. 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.

16. 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’

17. 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

19. 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.

20. 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

21. 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 effi ciency
