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 efficiency
