Bag dust collector DMC series

pulse-jet backflow

DMC Pulse Bag Deduster 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. 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. 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.
