Water-repellent and oil-proof needle felt filter bag; during the operation of bag filter, if the gas contains more water and oil and moisture easily deliquescent dust, the water film will be generated to increase the holding property, which will make the dust difficult. Especially for high temperature and high humidity gas, due to the cooling effect of external gas, the phenomenon of exposure occurs, and the collected dust is blocked on the surface of the filter material, increasing the operating resistance of the dust removal equipment, which directly affects the normal operation of the dust removal equipment. Water and oil repellent needle felt adopts special surface post-treatment technology, which greatly improves the anti-bonding property and dust stripping property of the filter material, and can effectively prevent water and various oil stains from staining and penetrating.
