How to recover trace amounts of powder entrained in the gas stream of a bag filter? It’s very expensive. This post was last edited by DAC The army rules the world on 2008-9-16 22:06.]
The washing method should be feasible, mainly by selecting an appropriate washing medium based on the properties of the solid.
Dry recovery: A set of cyclone separation equipment is connected in series after the gas phase to recover the powder. Wet recovery: The gas enters the lower water tank from a higher position, and the powder settles in the tank for recovery. However, this method is not suitable for lightweight powders or powders that are prone to hydrolysis.
Try electrostatic adsorption~~! ! !
Bag filters are not easy to collect, and cyclone separation is rather difficult. Both washing and static control are quite good!
It’s difficult; static electricity dust removal is the only option!

It contains a trace amount of powder, and the quantity is estimated to be small. How much did the previous set of electrostatic equipment cost? Let’s see if it’s worth it!
The dust that cannot be separated by bag filters is quite fine, and it is difficult to separate it using other methods. The efficiency of electrostatic dust removal is inferior to that of bag dust removal. Power plants previously used electrostatic dust removal on a wide scale; however, as environmental standards became stricter, it became necessary to switch from electrostatic to bag dust removal. The dust removal efficiency of cyclone separators is far inferior to that of electrostatic precipitators, and it is even incomparable to that of bag filters. The washing effect is acceptable, but it’s quite troublesome to deal with such fine powder in water. Separation is only possible through filtration. I think the best solution is to work on the existing filter bags. Minimum investment, fastest results.
