Abstract

The invention relates to a composite filter cloth equipped with a filter membrane. The composite filter cloth is composed of a filter cloth and a filter membrane. The filter cloth includes a glass fiber filter cloth, a polytetrafluoroethylene filter cloth or basalt filter cloth, the surface of the filter cloth is provided with the filter membrane, the filter membrane includes a polyvinyl fluoride filter membrane, and the filter cloth and the filter membrane form an overall structure through bonding or hot pressing compounding. The filter cloth also includes a filter cloth formed by blending of glass fiber and polytetrafluoroethylene fiber or basalt fiber and polytetrafluoroethylene fiber. The composite filter cloth consists of two layers of filter cloth, and the filter membrane is arranged between the two layers of filter cloth, wherein at least one layer of the filter cloth is provided with the filter membrane on the external surface. Compared with the prior art, the filter cloth and the filter membrane are compounded to form the multilayer composite filter cloth, which not only can filter out dust particles with a diameter of less than 2 micrometres, but also enhances the strength of traditional filter cloths and filter membranes, thus being applicable in industrial dust removal equipment for a long term. The composite filter cloth equipped with a filter membrane provided by the invention ahs long service life and good dust filtration effect.

Description

technical field [0001] The invention relates to a filter cloth, in particular to a composite filter cloth provided with a filter membrane for industrial dust removal equipment. 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. Existing filter cloths are difficult to filter out dust particles with a diameter of less than 2 microns. The existing filter membrane has low strength and is difficult to withstand the high wind pressure of the dust collector for a long time. It is easily damaged during the dust removal process of the dust removal equipment and has a short service life, which affects the filtration and dust removal effect of the dust collector. Contents of the invention [0003] In view of the above deficiencies of the existing dust removal filter cloth, the purpose of the present invention ...
