The invention relates to the technical field of bag type dust removal, in particular to an anti-corrosion filter bag. The anti-corrosion filter bag comprises a neck ring. Annular filter cloth comprises outer-layer cloth and inner-layer cloth. A reinforcing anti-corrosion layer is arranged between the outer-layer cloth and the inner-layer cloth. The outer-layer cloth, the inner-layer cloth and the reinforcing anti-corrosion layer are connected in a press fit mode. A spring penetrates into the outer-layer cloth. The reinforcing anti-corrosion layer comprises multiple transverse protecting ribs, multiple longitudinal protecting ribs and a polytetrafluoroethylene layer. Annular protecting ribs are arranged between the longitudinal protecting ribs and the transverse protecting ribs. Connecting parts are connected between the annular protecting ribs and the longitudinal protecting ribs and between the annular protecting ribs and the transverse protecting ribs. The transverse protecting ribs, the longitudinal protecting ribs and the annular protecting ribs are coated with the polytetrafluoroethylene layer. The anti-corrosion filter bag is good in anti-corrosion performance, cannot be corroded, and is longer in service life and not prone to deformation, and the filtering performance and the mechanical performance of the filter bag can be kept at a high level.
Description
technical field [0001] The invention relates to the technical field of bag type dust removal, in particular to a corrosion-resistant filter bag. Background technique [0002] The filter bag has excellent chemical performance stability and heat resistance. It is the representative of the highest performance in the filter material industry, and it is also the most high-end variety of all commonly used filter materials. Level, sometimes it is necessary to deal with corrosive substances. Once the corrosion resistance of the filter bag is not good, the filter bag will be corroded, and the service life of the filter bag will be shortened, resulting in deformation of the filter bag. The filtration performance and mechanical properties of the filter bag drop, for which we propose a corrosion-resistant filter bag. Contents of the invention [0003] The object of the present invention is to solve the disadvantage of poor corrosion resistance of the filter bag in the prior art, and ...
