Overview

    The pulse bag  filters made by our company are being used  in  the industry of nonferrous metal, power , mine, metallurgy,  food, etc.

During normal operation, dust air is drown into air inlet manifold under the action of ventilator, then is evenly distributed to each inlet chamber through inlet branch and then is flown into filter bag. Large quantity of dust is retained on the filter bag, in which air stream passes through. Purified air stream flows into bag chamber and then is discharged into the atmosphere through the smoke pipe.

With the increase of dust attached on the surface of the filter bag and growing resistance, regular dust cleaning is needed to make the resistance fall to specified limit so that the dust remover can enter into normal operation. Dust cleaning is mainly completed by high pressure gas storage bag, solenoid valve, blowing pipe and dust removing controlling mechanism. Firstly, solenoid valve is automatically turned on by the operation system rapidly; high pressure air back blows via blowing pipe to make dust attached on the filter bag shake into the dust hopper. And then dust cleaning is finished after solenoid valve is turned off. Filter bag is resumed to filtering state. Other solenoid valves are turned on by the operations system to conduct dust cleaning on other filter bags. Dust cleaning recycling goes through all the filter bags and the dust removing effect is achieved. Dust remover completely switches to filtering state and dust in the hopper is discharged to conveyor from ash valve at the bottom.

This remover adopts external filtration, down feed operation modes and pulse back-blowing dust removing. The fiberglass needle penetrated filtering material is a newly developed efficient material that can operate at high temperature. It is a new type of high temperature resistant filtering material with reasonable structure and excellent performance. With stable dimension and high strength, this dust remover is not only high temperature resistant, but also corrosion resistant. Besides, it has low filtering resistance for gas and higher dust removing efficiency than fabric filtering materials, reaching 99.9%. Its filtration rate is almost as twice that of fabric filtering materials.

 

Characteristics

    1) The pulse bag  filter  is composed of upper box, middle box, bottom box, dust hopper ,  inlet ?ue, outlet ?ue, blowing dedusting device and scrubbing adsorption  reaction channel, etc..

    2) The multilevel air de?ector is installed on the gas impulse face of the inner wall of the inlet large elbow so that the life span of the large elbow is greatly prolonged.

    3) The  long bag cage  is divided  into  two parts and  they are connected by self-lock bayonet coupling so that the bag cage structure can be optimized.

    4) The  thickness of ori?ce plate  is changed  toδ=8  fromδ=6,so  that  the mechanical strength  is greatly  improved, which keeps  the ori?ce plate  in a state of ?at and  free  from deformation in operation.

 

 Working Principle 
      The dusty gas goes  through  the reactor via main ?ue  into  the  inlet ?ue of  the bag ?lter . Afterwards  the gas enters  the bottom box and  is evenly distributed  to each unit by gas distribution plate. Because the speed of the gas  falls rapidly after  it enters the unit, coarse dust particles  in  the gas are naturally drop  into  the dust hopper  for  its deadweight while  fine dust particles are absorbed on  the  filter bag at  last going with  the movement of  the gas. The scrubbed gas enters  the upper box  (the scrubbed gas  room) and  then goes into stack via outlet ?ue and induced fan for emission into air . Along with the ?ltration of bag ?lter ,  there will be more and more dust deposited on  the surface of ?lter bag and the  resistance of  the  filter bag continuously  increases. When  the  resistance  increases  to a certain volume,  the sensor detects out  this and sends a signal  to  inform  the controlling system. After the controlling system gives the signal, the pulse controller is started to work
and  it  turns on  the pulse valves successively at scheduled  intervals, so  that  the ?lter bag can be blew and dedusted by  the compressed air  through nozzle. The sharp  increase of pressure makes sudden expansion  to  filter bag  for dedusting by  rows. Furthermore,  the control system allows  timing controls  to  the blowing system so  that  the dust can be blew and collected at  the scheduled  time and ?nally drop  into  the hopper . Thus  the dust  in  the hopper wilbe removed through dedusting system or be conveyed to a designated position through dust conveying system.

Application

     Pulse Bag Type Dust is extensively applied to grain, foodstuff, metallurgy, chemical, medicament, construction material etc industries for solid separation and powder recovery. Pulse Bag Type Dust Collector is used to separate dusts from air that contains them, as then, air containing dust acquires high purity once passing through filter medium ,in order to satisfy requirements of modernizing environment protection.
