Industrial dust filter :

Bag filter is a kind of dry dust filtering device.

After a period of time,due to the screen,collision,stranding,diffusion,electrostatic effect,such as a layer of dust accumulation on the surface of filter bag,at the beginning of the dust layer is called layer,after the movement process,early become the main filter to filter material layer,depending on the role of the first layer.large mesh filter material can also get higher filtration efficiency.

As in the accumulation of dust on the surface of the filter material,filter efficiency and resistance are corresponding increase,when the pressure difference on both sides of the filter material is very big,can put some tiny dust particles are attached to the filter material has been squeezed in the past,the dust collector efficiency decline.In addition,the resistance is too high will make the system of dust control of air volume dropped significantly.

Filter resistance after reaching a certain value,therefore,to timely remove and ash removal could not be broken when the first layer,so as to avoid the efficiency decline.

With powder repeat attached to the filter bag surface,the powder layer thickening and flow resistance value also increase;Pulse valve diaphragm issue instructions,around submerged pulse valve opens,the high pressure gas compressed air through the package,if there is no dust or small to certain degree,mechanical soot cleaning work will stop working.



 

Advantages:

1.Dust removal efficiency is high,generally over 99%,precipitator dust concentration of outlet gas in dozens of 50mg/m³,the fine dust of submicron particle size high classification efficiency.

2.Simple structure,convenient maintenance operations.

3.Under the premise of guarantee same high dust removal efficiency,cost is lower than the electric dust catcher.

4.Using glass fiber,the high temperature resistant filter materials such as ptfe,P84,can run under the condition of high temperature above 200ºC.

5.Is not sensitive to the characteristics of dust from dust and influence of the resistance.
