Abstract

The invention relates to the technical field of filter dust removers and specifically discloses a long-acting electrified filter material and an electrostatic filter dust remover. The filter materialcomprises at least one of a pure conductive fiber felt, a conductive fiber blended felt, a conductive fiber laminating felt, a conductive coating filter felt, a conductive rib filter felt, a metal netfilter felt and a magnetron sputtering electroplated metal layer filter felt. The long-acting electrified filter material is simple in preparation process and low in gram weight, and the raw materialcost is reduced. Meanwhile, the dust remover is low in operation resistance, large in flux, easy to remove dust, long in service life, convenient to replace and low in operation cost.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a long-term charged filter material and an electrostatic filter dust collector. Background technique [0002] At present, electrostatic dust removal and bag dust removal are the mainstream dust removal technologies in industrial dust removal, which have high dust removal efficiency, but each has its own advantages and disadvantages. Electrostatic dust removal is to separate the dust particles from the gas by charging the dust particles and then being adsorbed by the negative / positive electrode plate; its running resistance is low, and the emission concentration is usually 50-100 mg / m3, but the dust removal efficiency is affected by the specific resistance of the dust Influence, the specific resistance should not be too large or too small, usually it is difficult to capture the fine particles of PM2.5, so its smoke and dust emission concentration is difficult to meet the national ...
