Constructions:
Panel construction is from mild steel with welded &
sealed joints. Panels are suitably ribbed. Bag inspection
panels are incorporated in casing. The clean air chamber
is fitted with removable lids are sloped slightly for
drainage of water, as many times, filters are placed
for outdoor duty.
Compressed Air Equipments:
Heavy duty steel pipe forms the distribution manifold
1" NB sockets at both ends. One end the filter/regular
is fitted. Tank has drain connections at the bottom.
The valves are provided with canopy or hinged cover
for outdoor applications. Pulse jet dust collector valves
are quick acting diaphrams type with pilot solenoid
operations.
Filter Fabrics:
Polyester felt has proved to be suitable for majority
of applications. Other fabrics are available where nature
of dust or conveying air demands alternate materials.
Polypropylene, polyester, acrylic, fiberglass, nomex,
ryton, P84, teflon fabric bags for temperatures from
77 degrees C to 260 degrees C are available.
Pleated Bags:
We can also fit pleated bags in the same body, as we
provide same size bags as that of bags with pleated
construction to increase filter area 100 to 200%.
Special Bag Treatment:
Bags can be conditioned to absorb hydrocarbons and moisture
and increasing efficiency. Antistatic/spark inhibiting
treating is also possible.
Solenoid Valves & Electronic
Controller:
Pulse Jet dust collector valves are located in protected
area, and easily accessible. They are pilot operated
solenoid valves, are two way normally closed type initiated
by 215V signal. Controller incorporates the latest microprocessor
technology with variable controls for interval between,
and duration of, pulse. Light emitting diode flashes
as each output is energised in sequence.
Description & Operation:
Filter unit comprises of housing and number of filtering
elements with wire cage supported cylindrical bags made
from fabric, each bag being mounted individually into
filter body with bag / cage / ventury sub-assembly.
Air for pulse jet cleaning is carried by tubes running
above the rows of bags to jet nozzles projecting into
ventury throats. Rapid acting diaphragm valves are triggered
by solenoid pilot valves which in turn are controlled
by electronic timer.
Dusty air passes from outside of bag surface. The precast
pulse at interval keeps cleaning rows one after another,
while rest of the filter is in the operation continuously.
No tool bag change is possible with removal of wing
nut on union, which enables to remove ventury and cage
leaving bag inside.
