Abstract
A piece of composite filter cloth relates to a kind of filter material, in particular to a piece of composite filter cloth containing blended fiber filter cloth of basalt fiber and polytetrafluoroethylene fiber. The utility model provides a piece of the composite cloth which has excellent flexibility resistance, corrosion resistance and abrasive resistance, and can be used as filtering material under high-temperature. The composite filter cloth is provided with at least two layers of filter cloth, wherein at least one of layers of the filter cloth is blended fiber filter cloth which contains basalt fiber and polytetrafluoroethylene fiber. The composite filter cloth is applicable to the high-temperature smoke filtration in the industries, such as waste incinerators, the carbon black chemical industry, steel, metallurgy, coal-burning boilers, refractory materials, cement and the like, and is an ideal high-temperature composite filter material.
Description
Technical field
The utility model relates to a kind of filtering material, especially relates to a kind of compound filter cloth that contains basalt fibre and polytetrafluoroethylene fibre composite fibre filter cloth.
Background technology
At present, be used for the filtering material of high temperature environment such as industrial flue gas cleaning, have and adopt pure basalt fibre to make.Basalt is inorfil, has advantages such as noninflammability, temperature tolerance (269～700 ℃), the discharge of no toxic gas, good, the no fusion of thermal insulation or drippage, intensity height, no thermal contraction phenomenon.But because basalt fibre is crisp easy to break, folding resistance, anti-wear performance are relatively poor, corrosion resistance to some chemical substances is also relatively poor, therefore, there is above-mentioned defective in the filtering material that uses simple basalt fibre to make, when using in particular for hot environment its service life shorter, cause in application facet to be very restricted.
Notification number provides a kind of basalt fibre filter cloth for the utility model patent of CN201026420.Comprise base cloth layer and at least one felt-cloth layer, described base cloth layer and felt-cloth layer are combined as a whole after main acupuncture is handled.This basalt fibre filter cloth resistance to elevated temperatures is good, can be-260～700 ℃ of following operate as normal, can adapt to various complex operating environment and working condition, can be used for gathering dust of carbon black, refractory material, blast furnace flue gas, be specially adapted in the filter bag of strong purge mode such as pulse jet.
Summary of the invention
The purpose of this utility model provides a kind of have good folding resistance, corrosion resistance and wearability, can be used as the compound filter cloth of hot environment filtering material.
The utility model is provided with at least 2 metafiltration cloth, and wherein at least 1 metafiltration cloth is the composite fibre filter cloth, and described composite fibre filter cloth is the composite fibre filter cloth that basalt fibre mixes with polytetrafluoroethylene fibre.
The described at least 2 metafiltration cloth that are provided with can be that every metafiltration cloth is the composite fibre filter cloth, also can be that at least 1 metafiltration cloth is the composite fibre filter cloth, and the remainder layer filter cloth is at least a in basalt fibre filter cloth, polytetrafluoroethylene fibre, the glass filter cloth etc.Connected mode between each metafiltration cloth can be acupuncture or bonding.
The utility model can adopt following method preparation:
1) preparation composite fibre
Basalt fibre is mixed with polytetrafluoroethylene fibre, get composite fibre;
2) prepare similar compound filter cloth
Add in composite fibre that antistatic additive carries out and hair, carry out shredding-combing-lapping-web layer-acupuncture-finalize the design-singe-press polish-finished product again, obtain the individual layer compound filter cloth---the basalt fibre of individual layer and the composite fibre filter cloth of pure polytetrafluoroethylene fibre; Can add in composite fibre also that antistatic additive carries out and hair, carrying out shredding-combing-lapping-web layer-close thorn-sting again-finalize the design-singe-press polish-finished product again, obtain the MULTILAYER COMPOSITE filter cloth---each layer is the composite fibre filter cloth of basalt fibre and pure polytetrafluoroethylene fibre;
3) prepare dissimilar compound filter cloths
It is compound that above-mentioned individual layer compound filter cloth and other filter cloth are carried out lamination, and the quantity of lamination and arrangement mode can be selected arbitrarily, and described other filter cloth is preferably existing basalt fibre filter cloth, polytetrafluoroethylene fibre filter cloth or glass filter cloth; It is compound perhaps above-mentioned MULTILAYER COMPOSITE filter cloth and other filter cloth to be carried out lamination, and the quantity of lamination and arrangement mode can be selected arbitrarily, and described other filter cloth is preferably existing basalt fibre filter cloth, polytetrafluoroethylene fibre filter cloth or glass filter cloth.
The utility model is a kind of very good high-temperature composite filter material applicable to the fields such as high-temperature flue gas filtration of industry such as incinerator, carbon black chemical industry, iron and steel, metallurgy, coal-burning boiler, refractory material and cement.This is because the polytetrafluoroethylene (PTFE) fiber has good folding resistance, performance such as corrosion resistance and wearability, and basalt fibre has heat-resisting quantity, polytetrafluoroethylene fibre and two kinds of materials of basalt fibre can be formed the high performance filtering material of a kind of new structure after compound, this composite has excellent physics and chemical property as high-temperature-resistant filtering material, basalt fibre and polytetrafluoroethylene fibre advantage can be merged, make the utility model can improve the service life of filtering material effectively, acid and alkali-resistance degree height, the rate of filtration is fast, pollution control is effective, satisfy fume high-temperature and filtered the needs of industry, be applicable to high temperature, high humidity, high viscosity dust industry or have Acidity of Aikalinity, the industrial fumes of aggressive chemistry gas purify and the abominable occasion of other operating mode.Overcome equipment running resistance height, long-term unsolved difficult problems such as the early stage embrittlement breakage of filtrate.
Basalt fibre is the high-performance fiber of environmental protection, not only performance such as temperature tolerance (269～700 ℃), resistance to chemical attack, water-fast, acid resistance and anti-steam stable all is better than glass fibre, and has characteristics such as elastic modelling quantity and intensity height and density are big.And polytetrafluoroethylene fibre is not only high temperature resistant, and its fiber fusing point is 327 ℃, and has advantages such as anti-high humidity, corrosion-resistant, hydrolysis, and the oxide etch that can bear various strong oxides simultaneously has good low friction and advantage such as wear-resistant again.Therefore basalt fibre and two kinds of materials of polytetrafluoroethylene fibre are compound has a good enhancement effect.And the main component of high-temperature flue gas is flue dust, SO
2, NOx, CO, HCl, fluoride etc., this shows that basalt fibre and PTFE fiber composite Nomex relatively have tangible advantage as filtrates such as high-temperature flue gas filtration material and aramid fiber, glass fibre, polyphenylene sulfide, polyimides, terylene, polypropylene fibre, KERMEL.No matter be its corrosion resistance, wearability and fatigue durability, or its tensile strength all is better than the filtrate that ordinary filter and simple basalt fibre or simple PTFE fiber are made.The heat-resisting quantity of this kind combined high temperature filtrate mainly is the heat resistance decision of basalt and PTFE itself, and its long-term serviceability temperature is 260 ℃, and short-term and moment can reach 280 ℃; It has good acid-proof alkaline, all has extraordinary repellence for Acidity of Aikalinity and most organic matter; Thermal dimensional stability good (280 ℃, thermal contraction is less than 1%), this characteristic has determined the security that it at high temperature uses; And basalt and PTFE fiber have good low friction, and easy-to-clean ash has determined it to have good rub resistance and fatigue durability; These characteristics have determined it to have higher filtration velocity, good filter effect and long service life etc.
