Session 2 Bag filter dust collector monitoring

Factors not as consideration during purchase bag filter dust collector? (Faktor yang tidak perlu dipertimbangkan semasa pembelian bag filter dust collector)

• Dust loading

• Efficiency required

• Cheapest price

• Air to cloth ratio

Centrifugal fan is air moves perpendicular to the rotational axis of impeller

• True

• False

All advantages for the axial fan EXCEPT

• Little ductwork required

• Lower power usage

• compact design

• noisy

All disadvantages for the centrifugal fan EXCEPT?

• Use more power and consume more energy

• Expensive

• low air volume

• high pressure application

Fan performance is typically defined by a plot of developed pressure and power required over a range of fan generated air flow

• FALSE

• TRUE

• Read air tanks pressure

• Measure air flow

• Measure voltage, resistance and current

• Measure different pressure across baghouse filter bags

Purpose monitor pressure drop of filter?

• To know actual condition of bag filter

• Ensure air flow rate enough for suction

• Ensure incoming gas temperature is not exceeding the bag filter limition

Which one are the pulse jet component?

• Air manifold tank

• Cell plate

• Venturis

• All Above

Not common problem for cleaning system for bag filter dust collector?

• Cracked diaphragm

• Moisture in the line

• Solenoid coil loose

• Blow pipe nozzle at the center

If pressure, frequency, amplitude setting too low will causes dust cake layer can build up too thick and bags don't get cleaned

• TRUE

• FALSE
