Professional Design Dust Collector Bag House - Water-repellent and Oil-expellant Polyester Needle-punched Felt Bag – Xintian

The waterproof grade of polyester two-pruned felt filter bag reaches level. It also ensures that the polyester two-pruned felt filter bag is not easy to block in the environment with large humidity, which greatly increases the service life of the filter bag and reduces the difficulty of manual operation. At the same time, the surface of the polyester two-prick needle-proof felt filter bag is smooth and the air permeability is good, which ensures the characteristics of the outer filter surface of the polyester two-prick needle-proof felt filter bag is easy to peel and easy to regenerate the filter cake layer. Note: In general, if the acidity of dusty gases is very small, the dew point temperature is 40-60 ° C and if the acidity is large, the dew point temperature may be as high as 120 ° C. Dacron waterproof and oil proof cloth bag in the process of bag filter operation, for the dust in the gas contains more moisture and oil and hygroscopicity and easy to release dust, on the surface of the dust may generate water film or oil film and increase the adhesion, although it helps to collect dust, but will make it difficult to remove ash. Especially when the high temperature gas is in the high humidity state, the condensation phenomenon occurs due to the cooling action of the external gas.This can not only make the collected dust scale on the surface of the polyester waterproof and oil-proof cloth bag, or even jam, but also corrode the structural materials, increase the operating resistance of the dust collector, and directly affect the normal operation of the bag type dust collector.
Dacron waterproof and oil proof cloth bag is widely used in mine dust removal, blast furnace pulverized coal injection of steel plant, cement plant, coal transport system of power plant, etc.

The filter cloth is rolled and impregnated with PTFE (waterproof agent), which is used in occasions with high moisture content. The filter material is not easy to block the paste bag, the service life of the cloth bag is prolonged, the gas flow rate is increased, and the maintenance cost is greatly save.
