Overview

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. 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.
