Chemical corrosion-resistant filter material

Abstract

The invention discloses a chemical corrosion-resistant filter material. Another two ends of connecting pieces are both fixedly connected with filter basin bodies through fixing mechanisms; a fine fiber layer is located on the outer surface of a filter material body; a coarse fiber layer is located on the inner surface of the fine fiber layer; a base cloth layer is located on the inner surface of the coarse fiber layer; an acid and alkali-resistant protective film is located on the inner surface of the base cloth layer; a basic layer is located at the inner part of the acid and alkali-resistantprotective film; installing grooves are located at the inner side of the filter basin bodies; the upper ends and the lower ends of the installing grooves are both fixedly connected with installing pieces; one side, which is close to a clamping piece, of each installing piece is fixedly connected with a limiting piece. The chemical corrosion-resistant filter material disclosed by the invention isnovel in structure, two fiber layers in different specifications adopt a grid structure formed by PTFE (Polytetrafluoroethylene) fiber bundles, the chemical corrosion resistance of the filter materialcan be stronger, dust can be easily stripped, and the service life of the filter material is greatly prolonged while the functionality of the filter material is increased, so that not only the filtermaterial can be effectively fixed in a filter basin, but also the disassembling work of the filter material can be more rapid, and the practicability of the filter material is increased.

Description

technical field [0001] The invention relates to a filter material, in particular to a filter material resistant to chemical corrosion, and belongs to the technical field of filter material equipment. Background technique [0002] The filter material structure is the main and important part of the biological aerated filter. The biological aerated filter has the advantages of good effluent water quality, short hydraulic retention time, small footprint, low investment and operating costs, strong impact load resistance and convenient management. It is an environmentally friendly, economical, efficient and energy-saving new sewage treatment technology, which can realize the renewable and sustainable utilization of water resources. status quo.

Problems solved by technology

However, the existing filter material itself does not have good corrosion resistance, so that the internal structure of the filter material is greatly damaged after being eroded by various chemical reagents, so that the service life of the filter material is greatly improved. The existing filter material is often fixed in the filter tank, which makes it more troublesome to disassemble the filter material when it needs to be cleaned in the later stage. Therefore, it is urgent to design a filter material that is resistant to chemical corrosion.
