There is limitation of the product due to material, technique and fiber self structure, can not preferably meet above-mentioned needs.High heat filter fabric continues
To high temperature resistant, high-corrosion resistant, durability, low running resistance, low energy consumption and and feature direction develop.This trend is complied with, it is public
Take charge of the chemical stability that has using PPS fibers is good, fusing point is high, fine heat-resisting performance, it is corrosion-resistant, the performance such as will not hydrolyze and ground
The Project Product of hair, have the characteristics that high temperature resistant, filter efficiency are high, filtration resistance is small, good in oxidation resistance, can be in high temperature, humidity
Used with having under conditions of chemical substance, steel, cement, coal chemical industry, the height of multiple industries of organic chemical industry can be widely used in
Warm flue gas ash removal.It is good in economic efficiency, wide market.
The content of the invention
The purpose of this utility model be to provide it is a kind of simple in construction, have high temperature resistant, filter efficiency are high, filtration resistance is small,
The high-efficiency low-resistance PPS filtering high-temperature flue gas cloth of good in oxidation resistance.
What the purpose of this utility model was realized in：
A kind of high-efficiency low-resistance PPS filtering high-temperature flue gas cloth, it is fine that the high-efficiency low-resistance PPS filtering high-temperature flue gas cloth includes PPS
Dimension composition meets knoisphere, the bottom that the base cloth layer of supporting role, PPS fibrages form, described to meet knoisphere and base cloth layer, base cloth layer
Formed with the bottom lapping that intersects, described to meet knoisphere surface covering anti oxidation layer, knoisphere, base cloth layer, the bottom of meeting passes through
Acupuncture links reinforcing.
The utility model is further arranged to, and is additionally provided with fibrous layer outside the anti oxidation layer, is aluminium silicate fiber peacekeeping glass
Glass fiber mutually tangles the fibre web of formation.
The utility model is further arranged to, and the composition material of the base cloth layer is high strength base cloth.
The utility model is further arranged to, it is described meet knoisphere, bottom is the unordered netted knot that forms of tangling of PPS fibers
Structure.
The utility model is further arranged to, and the space between the PPS fibre single threads is N, N 0.01mm-0.3mm.
The utility model is further arranged to, and the PPS fiber filament diameters are 0.08-0.8mm.
The utility model is further arranged to, and the gross weight of every square metre of the base cloth layer is not less than 100g, and is not more than
130g。
The utility model is further arranged to, the total amount of antioxidants of every square metre of the anti oxidation layer be not less than
30g, and it is not more than 50g.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
1st, the utility model is to the fibre fineness of PPS fiber filter cloth base fabric institutional frameworks and fibrous layer by carrying out type selecting,
Then again by the rational lapping number of plies, having the utility model, high temperature resistant, filter efficiency are high, filtration resistance is small, anti-oxidant
The features such as property is good.
2nd, the utility model uses for reference the modification technology of PPS fibers, and the fiber surface of antioxygenic property is carried out to acupuncture filter cloth
Treatment technology is coated, overcomes the shortcomings of existing PPS filter clothes oxidation resistance.
3rd, the utility model aluminium silicate fiber peacekeeping glass fibre mutually tangles the fibrous layer of formation, improves the utility model
Resistance to elevated temperatures.
4th, the utility model meets the network structure that knoisphere, bottom and base cloth layer form for the unordered entanglement of PPS fibers, further
Under the high temperature resistant for improving product, being not easy to be oxidized causes breakage.
Brief description of the drawings
Fig. 1 is structure diagram of the present utility model；
Fig. 2 is the structure diagram of the utility model cross lapping.
Implication in figure represented by label：1- anti oxidation layers；2- meets knoisphere；3- base cloth layers；4- bottoms.
Embodiment
The utility model is further described with specific embodiment below：
A kind of high-efficiency low-resistance PPS filtering high-temperature flue gas cloth, it is fine that the high-efficiency low-resistance PPS filtering high-temperature flue gas cloth includes PPS
Dimension composition meets knoisphere 2, the bottom 4 that the base cloth layer 3 of supporting role, PPS fibrages form, it is described meet knoisphere 2 and base cloth layer 3,
The lapping that intersects of base cloth layer 3 and bottom 4 forms, described to meet the surface of knoisphere 2 covering anti oxidation layer 1, described to meet knoisphere 2, base fabric
Layer 3, bottom 4 link reinforcing by acupuncture.It is described to meet the surface of knoisphere 2 covering anti oxidation layer 1, by entering to the fiber surface of filter cloth
The special cladding processing of row, by surface physicses chemical technology, improves the antioxygenic property of PPS fibers, plays its high-efficiency low-resistance mistake
Filter effect.Knoisphere 2, base cloth layer 3, the bottom 4 of meeting links reinforcing by acupuncture, and the filtration resistance of filtering material has its aperture big
Small and porosity is determined.In general, aperture is bigger, and porosity is higher, and its resistance is smaller.But meanwhile if aperture is excessive,
Then filtering accuracy reduces.Therefore, the utility model to the fibre fineness of filter cloth base fabric institutional framework and fibrous layer first by entering
Row type selecting, high-efficiency low-resistance filter cloth is then obtained by the rational lapping number of plies again.
