three proof needle punched felt dust bag

The three proof needle punched felt dust removal bag is formed by using hydrophobic and oleophobic agents through immersion rolling, pre drying, and baking treatment. After drying, hydrophobic and oleophobic agents are attached to the surface of the filter fiber in a mesh pattern, thereby reducing the surface tension between water, oil, and the filter bag. This prevents the wet filter medium formed by water, oil, and dust from adhering to the surface of the filter bag, thus avoiding the phenomenon of bag sticking.

During the operation of the bag filter, the three proof needle punched felt dust bag may generate a water or oil film on the surface of the dust containing a large amount of moisture and oil, as well as moisture absorbing and easily deliquescent dust in the gas, which may increase adhesion. Although this helps to capture dust, it will make cleaning difficult. Especially when high-temperature gases are in a high humidity state, condensation occurs due to the cooling effect of external gases. This not only causes the captured dust to scale and even clog on the surface of the filter bag, but also corrodes the structural materials, increasing the operating resistance of the dust collector and directly affecting the normal operation of the bag filter.

The three proof needle punched felt dust removal bag can prevent water and various oil pollutants from penetrating, and compared with ordinary filter materials, it not only has characteristics, but also has anti caking and easy peeling properties for dust.

For airborne dust containing a high amount of moisture and oil, as well as hygroscopic and deliquescent dust, a water film may form on the surface of the dust to increase adhesion. Although this helps to capture dust, it will make cleaning difficult, especially when high-temperature gas is in a high humidity state, condensation may occur due to the cooling effect of external gas. This not only causes the captured dust to scale on the surface of the filter material and block, but also increases the operating resistance of the dust removal equipment, directly affecting its normal operation.

Three proof needle punched felt dust bag: The filter cloth is rolled and impregnated with PIFE, and used in situations with high moisture content.

The three proof needle punched felt dust removal bag is treated with fluorocarbon resin and PTFE impregnation, which makes it easy to capture dust on the surface of the filter bag for wet and dusty gases (especially for absorbent and deliquescent dust), avoiding and reducing the occurrence of bag sticking.

The filter material is less likely to clog the bag, and the service life of the bag is extended. By increasing the gas flow rate, maintenance costs are greatly saved.
