Abstract

The invention relates to a graphene modified filter bag. The graphene modified filter bag includes a bag body, the bag body includes a dust facing layer, a middle layer and a base cloth layer in sequence from outside to inside, a woven mesh layer is arranged between the middle layer and the base cloth layer, the woven mesh layer includes warp strips and weft strips, the warp strips and the weft strips are intertwined and woven into a mesh shape, the warp strips are made by intertwining graphene fibers, the weft strips are made by intertwining polyurethane elastic fibers, strip-type liner sheets are arranged between the adjacent weft strips, the strip-type liner sheets are of a hollow structure, and anion powder are contained in the strip-type liner sheets. Due to the arrangement of the woven mesh layer, on one hand, the toughness of the bag body is improved, on the other hand, the shape restoring ability of the bag body is improved, that is, the bag body can restore its original shape after its surface wrinkles in filtering. The invention further provides a filtering material of the graphene modified filter bag.

Description

technical field [0001] The invention relates to a graphene-modified filter bag and a filter material of the graphene-modified filter bag, belonging to the technical field of environmental protection equipment. Background technique [0002] The filter bag is a key part in the operation of the bag filter, and the cylindrical filter bag is usually hung vertically in the filter bag. The fabric and design of the filter bag should be as efficient as possible, easy to remove dust and durable. In the pulse and air box pulse dust collector, the dust is attached to the outer surface of the filter bag. When the dusty gas passes through the dust collector, the dust is collected on the outer surface of the filter bag, and the clean gas enters the inside of the filter bag through the filter material. The skeleton inside the filter bag is used to support the filter bag and prevent the filter bag from collapsing. [0003] After the existing filter bag is used for a long time, the dust wi...
