Abstract

The invention provides an anti-static needled felt dust collection cloth bag, which includes an internal skeleton and a filter layer wrapping the skeleton. The filter layer is a blended fabric of polyester fiber and conductive fiber with a diameter of 6-8 micrometers, and contains 70-80 parts by weight of polyester fiber and 20-30 parts by weight of conductive fiber. According to the anti-static needled felt dust collection cloth bag provided by the invention, the polyester fiber and the conductive fiber with a diameter of 6-8 micrometers are blended, the conductive fiber is uniformly mixed in the polyester fiber, so that the dust collection cloth bag has excellent anti-static performance and can be kept for a long term.

Description

technical field [0001] The invention relates to an antistatic needle-punched felt dust-collecting cloth bag, which belongs to the technical field of dust-collecting accessories. Background technique [0002] The bag filter is the most widely used dust collector in the cement industry. Its efficiency on fine dust particles (1μm ~ 5μm) is over 99%, and it can also remove dust particles of 1μm or even 0.1μm. The bag filter has relatively strong adaptability, is not affected by the specific resistance of dust, and does not have other pollution problems. Under the condition of selecting an appropriate filter aid, it can remove both solid and gas pollution in the gas at the same time. thing. Due to this feature, bag dust collectors are basically used at all discharge dust points in the cement industry. [0003] There are countless interlaced fiber covering layers on the surface of the filter cloth of the bag filter. The dust particles in the gas that are larger than the holes o...
