Bag house dust collector

1. Dust collector Introduction
Bag dust collector is a dry-type dust filtering machine.It is widely used for collectoring fine,dry and non-fibrous dust.Textile filter cloth or non-textile needle felt is used for the filter bags.
When dust air enters into the bag dust collector,big and heavy particles sediment by gravity and fall into the ash hopper,while air with fine dust gets filtered and cleaned when passes through the filter bags, fine dust is blocked on the surface of the filter bags and then fall into the ash hopper under the action of impulse.
2. System Model

3. Features
A. High filtering efficiency. Final dust concentration<50mg/m3
B. Wide range of air volume from several m3 to thousands m3,suits filtering flue gas from indutrial furnaces.
C. Simple structure,easy for maintenance.
D. Lower cost than electric dust collector.
E. Fibre glass,PTFE,P84 etc heat resisting filter bags can work above 200degress.
F. Not sensitive to dust features,dust filtering efficiency not influenced by dust or resistance.
4. Working Principle
Impulse bag dust collector is made of upper housing,middle housing,ash hopper,filter bags,injection device,lift valve,cinder valve,pulse valve,measuring and control system etc.  Dust air enters the ash hopper via the air inlet. Big particles fall to the ash hopper by gravity or inertial impaction while light dust enters the filtering area with the airflow. Dust is blocked on the external surface of the filter bags,and  filtered clean air is vented through a draught fan.
Resistance of the dust collector increases with the operation.When the resistance reaches a certain value,pulse valve send signal and reverse air flow is sent to the filter bags.Dust on the furface of the filter bags falls due to the shaking of the filter bags.
5. Applicable material
It is widely used in dust collection of metallurgy,building material,machinery, chemical,mining etc fields.
