Pulse Bag Deduster

Introduce Of Pulse Bag Deduster

DMC60-120 pulse bag collector is 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 systeBecause cleaning proceedes     separately toward a few groups of the filter bag in oder, 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.
