The pulse jet bag filters are used to clean dust laden gases emitted from
process equipment of material handling, grinding mills etc.
These bag filters are widely used in utility
boilers, cement, steel, sugar, chemical and pulp and paper industries.
Pulse Jet Bag Filter for Slag Grinding Mill
of bag filters:
The bag filters are sized and designed to maintain a
suitable air to cloth ratio depending on the application.
Multi module bag filters are manufactured with
properly designed inlet and outlet plenums for even gas distribution across all
the modules. To ensure the uniform gas distribution, CFD studies are carried out
using software tools like FLUENT, ANSYS etc.
temperatures are ranging from ambient to 240 Deg. C.
The operating pressures ranges from 500 to 1500 mm
The filter bags are manufactured from wide variety
of filter media/fabric with required surface treatments to suit different applications and characteristics of dust /
gas to be handled by the bag filter.
The casing of the bag filters is optimally designed
to house the filter bags and accurately fabricated to obtain optimum
performance of the system. The bag to bag distance and the casing is sized to
maintain low CAN velocity to minimize re-entrainment of collected dust.
Hoppers are designed
with a valley angle based on the dust characteristics in such a way that the
collected dust gets discharged in to the dust handling equipment easily.
holding plate / Tube Sheet:
The holes on the bag holding plate are cut
accurately on CNC laser cutting machines to ensure smooth surfaces and
to mount the bags along with cage and ventury with leak tight fitment.
Cages are designed to have proper tolerances to
obtain maximum bag life and manufactured under strict supervision to maintain
dimensional accuracy. The cages are inspected for their verticality and
The venturi is designed for lower air consumption
and to take higher pick up of secondary
air from the clean gases saving valuable compressed air.
of filter bags:
The pulsing of compressed air is through suitably
sized solenoids which are energized through microprocessor based programmable
timers. The cleaning of the bags is interlocked to the differential pressure of
the bag filter to avoid unnecessary cleaning, to enhance life of filter bags.
