Filter cloth with adhesive layer on surface

Abstract

The invention relates to a filter cloth with an adhesive layer on the surface. The filter cloth with an adhesive layer on the surface comprises a base cloth and a filter cloth, the base cloth is formed by weaving of monofilament, multifilament or yarn, the filter cloth is non-woven fabric made of thermoplastic fiber, the base cloth and the filter cloth form an integral structure by stacking connection, and the surface of the filter cloth is provided with an adhesive layer. The surface of the filter cloth is provided with several circular, conical, oval or rectangular convex bodies with a height of 0.5-3.5mm, and the adhesive layer includes resin adhesive. Compared with the prior art, the filter cloth provided by the invention is coated with the resin adhesive layer on the surface to further strengthen the filter cloth's ability of adsorbing and filtering dust with small particle size. The filter cloth with an adhesive layer on the surface provided by the invention has good dust collection and dust removal effects, and difficultly jammable filter bag, is suitable for various industrial dust removers, and can meet the environmental standards with high discharge requirements.

Description

technical field [0001] The invention relates to the technical field of filter cloth, in particular to a filter cloth with an adhesive layer on the surface used for industrial dust removal equipment. Background technique [0002] At present, the surface of the filter cloth used in the filter bag of the existing industrial dust collector is generally a flat structure. During the working process of the dust collector, the dust gradually accumulates on the surface of the filter cloth of the filter bag. When the dust accumulates on the surface of the filter cloth to a certain extent, the filter bag The difference between internal and external pressure is reversed, or the filter bag is vibrated by the blowing device of the dust collector, so that the dust on the surface of the filter bag shakes and falls. The filter cloth of the existing filter bag will be blocked after long-term use, and the amount of dust shaken off when the filter bag is vibrated is reduced, which not only affe...

AI Technical Summary

Problems solved by technology

The filter cloth of the existing filter bag will be blocked after long-term use, and the amount of dust shaken off when the filter bag is vibrated is reduced, which not only affects the filtering and dust removal effect of the dust collector, but also increases the breakage rate of the filter bag and reduces the use of the filter bag life

[0003] At present, the country's requirements for environmental protection are gradually increasing. The diameter of the dust particles filtered by the ordinary filter bag of the existing bag filter is relatively large, and there are still a large number of dust with small particle diameters that will be discharged into the atmosphere. For some environmental protection standards High industries can no longer meet the requirements
