Water and oil repellent needle felt filter bags can be used in his liquid filtration surface?

There are many kinds of filtration materials water repellent and oil repellent needle felt filter bags can be used in his liquid filtration surface? The answer is no. Liquid filtration as the name suggests is to filter out the impurities in the liquid, if the water and oil repellent that how to filter it, so the water and oil repellent filter bags can only be used in the air filtration above. Here we will talk about the performance of water and oil repellent filter bags.

In the bag filter operation process, the gas, such as containing more water and oil and hygroscopic easy to damp dust, generate water film and thus increase the support, will make the dust appears difficult. Especially high temperature and high humidity gas, due to the cooling effect of the external gas and the phenomenon of condensation, the dust collected in the filter surface scaling blockage, increase the dust removal equipment resistance, directly affect the normal operation of dust removal equipment. Water and oil repellent needle felt adopts a special surface treatment process, which greatly improves the anti-bonding and dust peeling properties of the filter media and effectively prevents water and various oil and dirt from staining and penetrating.

Needled felt filter bag is a non-woven filter bag, the surface of the special burnt wool treatment, needle felt filter bag can be acid and alkali resistance, high filtration efficiency, withstand 80-120 degrees Celsius temperature. Suitable for the use of most liquid filtration can effectively prevent fiber shedding pollution filtrate, fluffy and uniform three-dimensional filtration layer of solid and colloidal particles have a very high capture capacity, high strength of the long fiber filter bag filtration efficiency stability, longer service life.
Polyester needle punching felt water and oil repellent dust bag can effectively stop water and various oil and dirt from attaching and penetrating, compared with ordinary filter media, it not only has water and oil repellent property, but also has anti-caking and easy peeling property for dust. For dust entering the bag filter containing more water and oil, as well as hygroscopic and moisture-prone dust, a water film may be generated on the dust surface to increase adhesion.

For air dust containing more water and oil as well as hygroscopic and easily damped dust, water film may be generated on the surface of the dust to increase adhesion, which helps to trap dust, but will make it difficult to clear dust, especially when the high temperature gas is in a high humidity state, due to the cooling effect of the external gas and the phenomenon of dew, which not only can make the dust trapped in the surface of the filter media scaling and thus clogging, but also can make This not only makes the dust collected on the surface of the filter media clogged, but also increases the operating resistance of the dust removal equipment, which directly affects the normal operation of the dust removal equipment.
