Composite filter cloth

Abstract

The invention relates to the technical field of filter cloth, in particular to a composite filter cloth. The composite filter cloth is formed by weaving of a plurality of warps and wefts, the warps are made from glass fibers, polypropylene filament yarns or basalt fibers, and the wefts are made from polypropylene split films. One or two side surfaces of the filter cloth are provided with filter films which are polyvinyl fluoride films, and the filter cloth and the filter films form an integral structure through adhesion or hot-pressing combination. The composite filter cloth has advantages that by arrangement of the filter films, small-particle-size dust adsorption and filtration performances of the filter cloth can be further improved; by combination of the filter cloth and the filter films to form the composite filter cloth, strength of traditional filter cloth and filter films is improved while dust particles in diameter smaller than 2mm can be filtered out, and accordingly long-term application in industrial dedusting equipment can be realized, long service life, great filtering and dedusting effects, less proneness to blockage of filter bags and applicability to various industrial dedusting devices are realized, and high-emission-requirement environmental protection standards can be met.

Description

technical field [0001] The invention relates to the technical field of filter cloth, in particular to a composite filter cloth. . Background technique [0002] At present, the filter cloths used in existing industrial dust collectors generally include filter cloths made of filaments and spun yarns, or filter cloths woven from monofilaments and filaments. 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. And the cloth is difficult to filter out dust particles with a diameter of less than 2 microns. Contents of the invention [0003] In order to solve the above problems, the invention provides a composite filter cloth, the specific technical scheme is as follows: [0004] A composite ...
