Main technical characteristics of folded fabric bags
The folded bag is a new technology suitable for the existing pulse
jet bag filter. The technology does not need any structural changes
to the bag filter, and the design of the bag, the core component of
the filter, is almost revolutionary improved.
1) Direct substitution of the existing circular (elliptical) filter
bag and keel of the dust collector without structural modification
of the main equipment.
2) According to the design and requirements of the system, the
filter area can be increased by 50%-150%.
3) Reduce the pressure difference of the system significantly,
thereby improving the overall performance of the system and the
service life of the cloth bag.
4) Reduce the frequency of cleaning or extend the interval of
cleaning by a large margin
5) Compared with ordinary cloth bags, the efficiency of pulse ash
removal (the same filter material) is obviously improved because of
its special structure.
6) With the increase of effective bag spacing, the airflow rising
speed between bags decreases, which greatly optimizes the effect of
online ash removal.
7) The special design of bag/keel greatly reduces the fatigue
damage and intermittent emission caused by pulse injection.
8) The keel has no transverse supporting ring and large effective
contact area, which completely avoids the direct impact on the
cloth bag.
9) The filter area can be increased and the length of the cloth bag
can be shortened to optimize the operation of the system.
10) greatly reduce the amount of compressed air and the load of air
compressor and pulse valve
11) Load of fan is greatly reduced and energy consumption of system
is significantly reduced.
12) The cost of system maintenance (energy consumption, auxiliary
equipment, parts and manpower) has decreased significantly.
13) Any existing filters (polyester, polypropylene, acrylic, PPS,
aramid, P84, PTFE, glass fibers and all kinds of filters that meet
the requirements of the system and their various treatments,
including PTFE coating) may be used.
