Description
DMC*****0 pulse bag collectoris composed of five main
parts.
1. Top body: including upper maintenance gate and air
outlet.
2. Middle body: including perforated plate, maintenance
gate, filter bag, keel, venturi.
3. Lower body: including air intake, ash bucket,
maintenance gate.
4. Ash Discharge System: including spiral conveyor or
star ash valve powered by reducer.
5. Blowing System: including pulse controller,
electromagnet impulse valve, impulse pipe, air manifold.
Working Principle:
The dust air enters deduster’s
tank body through air intake, because the air current volume
expands suddenly, the flow speed reduces suddenly, ash of which
particles are larger separates from the air current including ash
as a result of the collision and the gravity, deposits into ash
bucket of lower tank body. Smaller particles are absorbed
sluggishly into the extine of filter bag due to various effects of
filter bag. The gas which was purified is discharged from air
outlet of top body through filter bag by venturi. As time going,
with the dust which is absorbed by filter bag’s surface growing,
with the air permeability of filter bag weakening, which causes the
resistance of deduster to increase unceasingly. To ensure the
resistance of deduster to be controlled in a limitative range, with
pulse controller sending signals, electromagnetic pulse valve is
opened following in order, which makes the compressed air in the
gas capsule jet out from each spray orifice of spray pipe to
corresponding venture (called primary wind), and then induces
ambient air (called secondary wind) which is a few times than
primary wind to enter the filter bag when the high-speed airflow
passes the venture, resulting the filter bag rapid expansion in an
instant, because the impact effect of reverse pulse air current
will disappear soon, the filter bag contracts sharply, so this
allows the dust accumulating on the filter bag’s extine to be
cleared. The falling dust is discharged through the ash discharge
system. Because cleaning proceeds separately toward a few
groups of the filter bag in order, and do not cut off the dust air
which needs to deal, so the processing capacity of deduster remains
invariant in the process of cleaning.
Brief Introduction of Blowing System:
It is the constitution of blowing system, impulse valve
port A links to the compressed air manifold, port B links to
impulse pipe, the controller gives the orders to control the
control-valve. When the controller doesn’t output signals, the
moving iron core of control-valve seals the exhaust port, impulse
valve is power off. When the controller sends signals, the pulse
back pressure chamber and atmosphere are interlinked by
control-valve, pulse valve opening, the compressed air spurts into
venture from gas capsule through pulse valve by the holes of spray
pipe, alters to the instantaneous positive pressure in filter bag,
realizes
cleaning.
