Description
Technical field
This utility model relates to a kind of filter felt, and it is excellent to be specifically related to a kind of water repellent oil preventing performance, and easy cleaning dust, uses
The filter felt of life-span length.
Background technology
Need to use pocket type during the industrial flue gas cleanings such as coal-burning boiler, waste incineration, smelting iron and steel, carbide chemical industry
Dust removal and filtration material, but the filter bag product of prior art, its hydrophobic and oil repellent performance is the best, and easily occurs sticking with paste bag, stifled bag
Problem, service life is shorter, and durability is poor.
Therefore, necessary a kind of reasonable in design of design research and development on the basis of prior art, not only have very
Good water repellent oil preventing performance is excellent, and easy cleaning dust, service life length filter felt.
Utility model content
For above-mentioned produced problem, this utility model provides a kind of feature of environmental protection strong, and reasonable in design, water repellent is grease proofing
Performance is excellent, and high temperature resistant, decay resistance is strong, and filtrate dust-cleaning efficiency is high, service life length water repellent grease proofing easy-to-clean ash filter felt.
A kind of grease proofing filter felt of water repellent, is pasted onto the composite fibre layer of base fabric upper and lower surface including base fabric, symmetry and sets
PTFE fiber microporous film layer in composite fibre layer surface；Described base fabric is formed by warp thread and weft yarns, described warp thread by
Polyphenylene sulfide and polyimides blending form, and weft yarn is conductive yam；Described PTFE fiber microporous film layer uses high-temperature hot press
Heat overlays on composite fibre layer；Described composite fibre layer acupuncture is on base cloth layer；Described composite fibre includes PPS fibrous layer, glass
Two or more composition in glass fibrous layer, PTFE fiber layer, P84 fibrous layer.
Compared with prior art, having the beneficial effect that this utility model oil easy-to-clean ash filter bag, the feature of environmental protection is strong, structure
Reasonable in design, it is difficult to tear, water repellent oil preventing performance is excellent, and high temperature resistant, decay resistance is strong, and filtrate dust-cleaning efficiency is high, is difficult to lake
Bag, service life is long, can be widely applied to the industrial flue gas cleanings such as coal-burning boiler, waste incineration, smelting iron and steel, carbide chemical industry,
There is important using value.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
It is illustrated as a kind of embodiment of the grease proofing filter felt of this utility model water repellent, is pasted onto in base fabric including base fabric 1, symmetry
The composite fibre layer 2 of lower surface and be located at the PTFE fiber microporous film layer 3 on composite fibre layer surface；Described base fabric is by warp thread
Forming with weft yarns, described warp thread is formed by polyphenylene sulfide and polyimides blending, and weft yarn is conductive yam；Described PTFE fiber
Microporous film layer uses high-temperature hot press heat to overlay on composite fibre layer, surface spikes hot pressing is removed by hot press, simultaneously
Surface is carried out the optical processing of hot pressing Asia so that smooth surface, reduce the water adhesive ability on surface and grease proofing effect；Described compound
Fibrous layer acupuncture is on base cloth layer；Described composite fibre is by PPS fibrous layer, glass layer, PTFE fiber layer, P84 fibrous layer
In at least two select compound composition.
