Abstract
The utility model discloses a basalt fiber high-temperature filter material which comprises a basalt fiber base fabric layer (2) and a mixed fiber felt surface layer, wherein the mixed fiber felt surface layer is divided into an upper layer (3) and a lower layer (1), and the basalt fiber base fabric layer (2) is positioned between the upper mixed fiber felt surface layer (3) and the lower mixed fiber felt surface layer (1). Compared with the prior art, the utility model can effectively prolong the service life of the filter material and improve the resistance to acid and alkali, has a higher filtration rate and a better filtration effect, meets the requirements of the high-temperature filtration industry, is widely applicable to the high-temperature, high-humidity and high-viscosity ash industry or the purification and product collection of industrial flue gas containing acidic, alkaline and corrosive chemical gas, and greatly improves the production efficiency and economic benefit of constructional engineering.
Description
Technical field
The utility model relates to a kind of hot environment dust removal and filtration cloth, is specifically related to a kind of filter cloth with new structure that is made by basalt fibre.
Background technology
In the industrial circle, as high temperature, high humidity, high viscosity dust industry or have the industrial flue gas cleaning of Acidity of Aikalinity, aggressive chemistry gas and product is collected, existing scheme is to handle by filter bag or filter cloth, but the hot environment dedusting is very high to the requirement of filter bag, and the equipment investment of cooling dedusting is too big, and effect neither be very desirable.
Along with the attention of society to environment, more and more higher to environmental protection requirement, requirement to the industrial discharge standard is also more and more stricter, there are many drawbacks in dust arrester in the existing scheme, effect is also undesirable, and the filtrate that is used for high-temperature dust removal mainly is several expensive organic fibers and the general glass fibre filtrate of performance.The basalt continuous fiber material is described as " new material of 21 century ", suitable with the carbon fiber mechanical property, have in addition also that chemical attack such as high temperature resistant, acid-fast alkali-proof, hygroscopicity are low, not oxidation and characteristic such as not flammable, and low price is an ideal filtrate at present.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of good dedusting effect is provided, and high temperature resistant, low-cost basalt fibre high-temperature filter material.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of basalt fibre high-temperature filter material, it is characterized in that comprising basalt fibre base cloth layer and mixed fibre felt surface layer, the mixed fibre felt surface layer is divided into the upper and lower, and the basalt fibre base cloth layer is between upper strata mixed fibre felt surface layer and lower floor's mixed fibre felt surface layer.
Further technical scheme is that the mixed fibre felt surface layer is basalt fibre and a small amount of other fibers.
Further technical scheme is that the basalt fibre base cloth layer is the basalt fibre fabric again.
Compared with prior art, the beneficial effects of the utility model are:
Compared with prior art, the utility model can effectively improve the service life of filtering material, acid and alkali-resistance degree height, the rate of filtration is fast, good filtration effect, satisfied the requirement of high temperature filtration industry, be applicable to high temperature, high humidity, high viscosity dust industry or have the industrial flue gas cleaning of Acidity of Aikalinity, aggressive chemistry gas and product is collected, the utility model is simple in structure, improve filter bag serviceability temperature scope, corrosion resistance and life cycle and filter bag filter efficiency by this scheme, improved the production efficiency and the economic benefit of architectural engineering.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, a kind of basalt fibre high-temperature filter material, comprise basalt fibre base cloth layer 2 and mixed fibre felt surface layer, the mixed fibre felt surface layer is divided into upper strata 3 and lower floor 1, basalt fibre base cloth layer 2 is between upper strata mixed fibre felt surface layer 3 and lower floor's mixed fibre felt surface layer 1, the mixed fibre felt surface layer is basalt fibre and a small amount of other fibers, and basalt fibre base cloth layer 2 is the basalt fibre fabric.
More than said a small amount of other fibers: as temperature resistant fibers such as quartz fibre, alumina silicate fibre, ceramic fibre, glass fibre, boron fibre, aramid fiber, P84 fiber, PPS fibers.It is 0～48% that other fibers add mass fraction.
The basalt ore is made the basalt fibre precursor behind melt drawing, through obtaining the basalt fibre twisted yarn after the twisting, obtain the basalt fibre fabric through after weaving again, i.e. base cloth layer in this programme 1.The basalt fibre precursor obtains buiky yarn after expanded, lack again to cut and obtain short yarn cutting, join yarn with the short yarn cutting of other fibers, through after carrying out pre-needling, main acupuncture on the lapping machine, obtaining basalt fibre needle punched filter material semi-finished product together with the basalt fibre base cloth after the combing, after through the water-fast processing of oil resistant, obtain the filtrate finished product, add stainless steel ring or plastic hoop again, and make by cutting and to obtain the filter bag finished product.
Learn by experiment, basalt fibre is as the excellent high-temperature filtering material, its performance can compare favourably with resistant to elevated temperatures ceramic fibre, have structural strength height, high temperature resistant, good endurance, corrosion-resistant (not only acidproof but also alkaline-resisting), do not absorb water, characteristics such as filter efficiency height, can be mainly used in the filtering material of high temperature (200～350 ℃) and superhigh temperature (more than 500 ℃).Basalt fibre filter material mechanical strength height, ultimate strength is general all more than 2000N, and percentage elongation is low, and the extension at break of basalt fibre itself has only 3%, thereby the filter bag dimensionally stable made from it, the dust-collecting efficiency height can reach 99%-99.5%, especially to the grit below the diameter 0.5mm, it is big that effect is more obviously handled fume amount, operation maintenance is convenient, easy to clean, longer service life.
Claims (2)
1. basalt fibre high-temperature filter material, it is characterized in that comprising basalt fibre base cloth layer (2) and mixed fibre felt surface layer, the mixed fibre felt surface layer is divided into upper strata (3) and lower floor (1), and basalt fibre base cloth layer (2) is positioned between upper strata mixed fibre felt surface layer (3) and the lower floor's mixed fibre felt surface layer (1).
2. basalt fibre high-temperature filter material according to claim 1 is characterized in that described basalt fibre base cloth layer (2) is the basalt fibre fabric.
