Abstract
The utility model discloses an anti-static polytetrafluoroethylene filtration bag which comprises a bag head, a bag body and a bag bottom which are made of polytetrafluoroethylene filtration materials, wherein the polytetrafluoroethylene filtration materials comprise base cloth; the base cloth is formed by twisting and stranding polytetrafluoroethylene filament fibers and stainless steel fibers and weaving the polytetrafluoroethylene filament fibers and the stainless steel fibers through warps and wefts; non-woven layers symmetrically cover the upper surface and the lower surface of the base cloth and are formed by polytetrafluoroethylene fibers or blending one or more of the polytetrafluoroethylene fibers and high-performance fibers such as polyphenylene sulfide, polyamide and polyamide-imide; and a stainless steel metal mesh layer is sewed to the edge of the bag body. According to the anti-static polytetrafluoroethylene filtration bag, the prepared filtration material can resist high temperature and corrosion, is high in conductivity, can durably eliminate static electricity and reduce fire or explosion caused by static electricity sparks and can be widely applied to high-temperature fireproof and anti-explosion dust removal in the fields of steel smelting, garbage burning, coal power plants, cement, chemical industry and the like.
Description
Technical field
The utility model belongs to high temperature, corrosive fume field of purification, relates to a kind of antistatic polytetrafluoroethylene (PTFE) filter bag.
Background technology
The used chemical fibre filtrates of Industrial Stoves smoke and dust treatment such as smelting iron and steel, waste incineration, coal-burning power plant, cement, chemical industry do not have electrostatic-proof function, and the flue dust that the part process section produces has characteristics such as flammable, explosive, friction is easy to generate a large amount of static in the process of using because between dust and dust, dust and the filtrate, as can not in time eliminating electric charge, will produce fire or explosion accident.The PTFE material has obtained extensive use owing to high temperature resistant, the corrosion resistance characteristic of its excellence in high-temperature smoke improvement field, but simultaneously owing to belong to non-polar polymer, is easy to produce static in the process of processing or use, thereby has limited its range of application.
Summary of the invention
In order to overcome the problem that there is the antistatic difference in existing filtering material, the purpose of this utility model is to provide a kind of antistatic polytetrafluoroethylene (PTFE) filter bag, this filter bag is high temperature resistant, corrosion-resistant, conduct electricity very well, and have permanent antistatic, be applicable to that Industrial Stoves such as smelting iron and steel, waste incineration, coal-burning power plant, cement, chemical industry are flammable, during explosive smoke administers.
To achieve these goals, the utility model is achieved through the following technical solutions:
A kind of antistatic polytetrafluoroethylene (PTFE) filter bag, it is characterized in that: this filter bag comprises bag head, bag and the bag end, make by the polytetrafluoroethylene (PTFE) filtering material at described bag head, bag and the bag end, this polytetrafluoroethylene (PTFE) filtering material comprises base cloth, this base cloth is woven mutually and forms by warp, latitude by polytetrafluoroethylene (PTFE) filament fiber and stainless steel fibre twisting Split Down; Upper and lower faces at base cloth is coated with nonwoven layers symmetrically; This nonwoven layers is that polytetrafluoroethylene fibre or polytetrafluoroethylene fibre and high performance fiber blend are made; Scrap (bridge) place at bag is sewed with the stainless steel metal stratum reticulare.
In the utility model, described high-performance fiber can be polyphenylene sulfide fibre, Fypro, polyamide-imide fibre, glass fibre one or more.The thickness of described stainless steel metal stratum reticulare is 0.3-1.5mm, and width is 5-15mm.
Antistatic polytetrafluoroethylene (PTFE) filtering material in the utility model can be widely used in Industrial Stoves smoke and dust treatment fields such as smelting iron and steel, waste incineration, coal-burning power plant, cement, chemical industry in the process of using, have high temperature resistant, corrosion resistant characteristics, can eliminate rapidly in use because of fricative static simultaneously, have lasting antistatic characteristic, reduce the generation of fire or explosion accident.
This filter bag described in the utility model is high temperature resistant, corrosion-resistant, conduct electricity very well, and has permanent antistatic, is applicable to that Industrial Stoves such as smelting iron and steel, waste incineration, coal-burning power plant, cement, chemical industry are flammable, during explosive smoke administers.

The specific embodiment
By reference to the accompanying drawings the utility model is further set forth.
As shown in Figure 1, a kind of antistatic polytetrafluoroethylene (PTFE) filter bag: this filter bag comprises bag 1, bag 2 and the bag end 3, and make by the polytetrafluoroethylene (PTFE) filtering material at described bag 1, bag 2 and a bag end 3.Fig. 2 is the structural representation of polytetrafluoroethylene (PTFE) filtering material in the utility model, this polytetrafluoroethylene (PTFE) filtering material comprises base cloth 11, this base cloth 11 is by polytetrafluoroethylene (PTFE) filament fiber and stainless steel fibre twisting Split Down, weave mutually and form by warp, latitude, Fig. 3 is base cloth network structure schematic diagram in the utility model.Upper and lower faces at base cloth 11 is coated with nonwoven layers 12 symmetrically; This nonwoven layers 12 is that one or more blending of polytetrafluoroethylene fibre or polytetrafluoroethylene fibre and polyphenylene sulfide fibre, Fypro, polyamide-imide fibre, glass fibre are made; Scrap (bridge) place at bag 2 is sewed with stainless steel metal stratum reticulare 4, and its thickness is 0.3-1.5mm, and width is 5-15mm.
The preparation method of antistatic polytetrafluoroethylene (PTFE) filter bag is as follows:
By polytetrafluoroethylene (PTFE) filament fiber and stainless steel fibre twisting Split Down, weave mutually and obtain base cloth by warp, latitude;
Symmetry is spread nonwoven layers in the above and below of base cloth, reinforces by acupuncture or water thorn and makes the polytetrafluoroethylene (PTFE) filtering material; This nonwoven layers is made by blending by one or more blending of polytetrafluoroethylene fibre or polytetrafluoroethylene fibre and polyphenylene sulfide fibre, Fypro, polyamide-imide fibre, glass fibre and is made;
The polytetrafluoroethylene (PTFE) filtering material is sewn into comprises bag head, bag and the filter bag at the bag end, the place sews on the stainless steel metal stratum reticulare at the bag scrap (bridge), thereby forms conductive channel, and electric charge is eliminated rapidly, obtains antistatic polytetrafluoroethylene (PTFE) filter bag.
