How to prevent low temperature condensation to cause blockage to filter bag


First, moisture is the biggest cause of clogged bags. The cause of moisture content is usually condensation at low temperature. In order to prevent such a situation, the following aspects should be paid attention to.

① Avoid improper boot;

② Avoid turning on when the dust collector resistance is high;

Restart the machine when there is condensed water on the surface of the filter bag after the shutdown of the dust remover. In this case, a large amount of dusty air and high humidity will cause the surface of the filter bag to be muddy. To prevent this, preheat the dust air at the inlet of the dust collector or precoat the dust layer.

③ Boot at below the dew point;

Dust collector operating below the condensation point, prone to problems, if uneven distribution of air intake, easy to cause the dust precipitator shell corrosion, therefore, should avoid dust precipitator working below the condensation point, insulation device should be used.

④ Air infiltration;

Air infiltration often occurs in the dust remover flange, access door or dust remover mobile device, if the seal is not strict, the external air into the dust remover, when dealing with high temperature exhaust gas, will be in the dust remover internal low temperature zone, resulting in low temperature condensation, corrosion dust remover caused by moisture bag.

Airslide Fabric

Air slide fabrics are used for the pneumatic conveying of fine dry powdery products such as cement. The air slide cloth divides the air slide into upper and lower chambers. The chamber is inclined at as low as 1.5°.Compressed air is injected into the lower chamber which then goes through the media and “fluidises” the cement powder. The cement then behaves like a fluid and “flows” down the length of the chamber.


Airslide is a semi-permeable textile cloth which allows air to pass through but not the products.

Airslide Fabrics other names are: airslide fabric,air slide fabric,air permeable fabric,fluidising fabric,fluidizing fabric,air slide belt,air slide canvas,aeroslide,airslide membrane,aeration pad, aeration fabric.air slide fabric in shipping,air slide fabric for silos,chute bottoms.
