Why does the non-woven polyester filter bag stick? What are the treatment methods?

September 17,2022

The non-woven polyester filter bag is resistant to acid and alkali corrosion in the whole pH range under the continuous working temperature of 240 ℃ and the instantaneous temperature of 260 ℃. The non-woven filter bag is self-lubricating and moisture-proof, and can withstand ultraviolet radiation. Therefore, the non-woven filter bag framework is required to be smooth and strict. The filter bag is more suitable for the corrosion resistance of the filter material and has a long service life. Next, we will take you to know why the non-woven filter bag sticks, and what are the treatment methods?

1. The dust itself is viscous, and the intermolecular force is large when thenon-woven polyester filter bagcontacts with the filter fiber. For example, oil particles, ammonium sulfate, nitric acid ash, etc. generated from denitration are used for desulfurization.

2. Some dust in the non-woven filter bag is not sticky, but easy to deliquescence. When the non-woven filter bag is retained on the fiber surface, it will absorb the moisture in the air and stay on the fiber, and the solution will form on the surface.

3. Nonwoven filter bags may not have strong dust adhesion, but they can absorb moisture in flue gas, and produce chemical recrystallization to produce new hydraulic substances or crystals.

The non-woven polyester filter bag formed on the surface of the filter material, such as cement clinker, desulfurization product calcium sulfate, is the debris of the key components of the bag filter in operation. Basically, the cylindrical filter bag is vertically suspended in the filter. The fabric and design of the filter bag should strive to filter, remove dust easily and be durable. The pulse in the bellows is in the dust collector. When the dusty gas passes through the dust collector, the dust filtered by the non-woven filter bag is captured on the outer surface of the filter bag, and the clean gas of the non-woven filter bag enters the filter bag through the filter material.

The above is an introduction to the adhesion phenomenon and treatment methods of non-woven filter bags that we sffiltech arranged for you. With these understandings, I believe it can be more reasonable in the future use process, and I hope it will be helpful to everyone.
