Description
Technical field
Patent of the present invention relates to a kind of air cleaning woven fabric, is specifically related to a kind of basalt fibre snow Neil woven fabric.
Background technology
Its heart yearn of chenille yarn of the prior art is to take acrylic yarn to form as raw material twisting, and camlet is to take spun rayon short plumage forms as raw material cuts into, and is widely used in house and spins and woven garment field.Adopt the common woven fabric of chenille yarn generally to get its decorative effect, its comfortableness aspect is poor more.Be rarely used in air filtration purposes.
China experienced " coal-smoke pollution " that the industrial revolution of 18th century brings and 19th century oil and auto industry " photochemical pollution " that bring afterwards, modern just experiencing take " serious PM2.5 type haze air environmental pollution " with Chinese characteristics be the 3rd pollution period indicating.The residing living environment of people is more and more severe now, and endless industrial discharged waste gas, the vehicle exhaust being seen everywhere have caused day by day serious air pollution.Haze weather, PM2.5 warn air-polluting to people and have a strong impact on.Industrialized process is increasingly strict to the demand of air cleaner, as dust proof workshops such as medical treatment, health, food, chemical industry, electronics, and clean room, laboratory and toilet, or dustproof for electric mechanical communication equipment etc.
Air cleaner is generally divided into just imitates the models such as air cleaner, middle effect air cleaner, high efficiency particle air filter and inferior high-efficient air filter.Filtering material has nonwoven fabric, nylon wire, activated carbon filtration cotton, metal hole pattern etc., and protection network has two-sided plastic-blasting wire netting and double side zinc coating wire netting.Inexpensive, lightweight, versatility is good, compact conformation.Filter material selects generally all will to consider resistance and the use problem of air cleaner, in case airborne suspended particle impacts to clean area, and guarantees filter service life.
Particulate in air removal technology mainly contains mechanical filter, absorption, electrostatic precipitation, anion and plasma method and the filtration of static electret etc.Mechanical filter is general mainly catches particulate by following 3 kinds of modes: directly interception, and inertial collision, Blang's diffusion mechanism, it is to fine particle thing collecting effect is good but windage is large, and in order to obtain high purification efficiency, filter core needs fine and close and regularly replaces.Absorption is to utilize the high surface area of material and loose structure to catch particulate pollutant, is easy to stop up, more remarkable for gas pollutant removal effect; Thereby electrostatic precipitation is to utilize high-voltage electrostatic field to make gas ionization make dust particles be adsorbed onto the collecting method on electrode, though its windage is little, to larger particles and fiber trapping weak effect, can cause electric discharge, and cleaning trouble is time-consuming, easily produce ozone, form secondary pollution.The operation principle that anion and plasma method are removed indoor particle pollutant is similar, all by making airborne particle charged, coalescent formation larger particles and sedimentation, but in fact particle does not remove, on near surface being just attached to, easily cause airborne dust again.Static electret filters that to take 3M " high efficiency electrostatic airstrainer " be representative, adopt the breakthrough permanent static filter material that carries, effectively intercept in air and be greater than the particulate pollutant of 0.1 micron, as dust, soft flocks, pollen, bacterium etc., super-low impedance is guaranteed air-conditioning stable operation and refrigeration simultaneously.In addition, longer service life is guaranteed in the design of degree of depth appearance dirt.At family and on-board air conditioner (as above vapour, masses, the famous brand name situation of selling well vehicle such as general) and some commercial building fields (as Bird's Nest, the Beijing Hotel, three phases of the Capital Airport), be used widely.Traditional standard filter media can be removed 10 microns of above particles very effectively.When the particle diameter of particle is except to 5 microns, 2 microns even during the scope of sub-micron, mechanical type filtration system will become more expensive efficiently, and windage can significantly increase.By static electret air filting material, filter, can with lower energy resource consumption, reach very high capture rate, have the advantage of the low windage of electrostatic precipitation simultaneously concurrently, but the voltage without external volts up to ten thousand, therefore can not produce ozone, and because it consists of polypropylene material, easily abandon processing.Such filtrate is more useful to low temperature contaminated air, and due to the restriction of fibrous material self, higher than the contaminated air environment of 130 degree, such material can not be used.
Terylene needled felt has more the filtering material of the efficient material of advanced function.General flue-gas temperature, not higher than 150 ℃, can select the flexible filter materials such as terylene needle punched non-woven fabrics, but industrial temperature is higher than more than 150 ℃, as chemical industry, carbon black tail gas, blast furnace coal gas, vertical cellar for storing things, cement plant tail gas, calcium carbide factory's cellar for storing things furnace exhaust gas, casting, steel-making flue gas, bituminous concrete stirs bitumen flue gas, coking flue gas, flue gas during smelting etc. are selected aramid fibre filter bag.The one, because these exhaust gas dusts are because being subject to be not suitable for the electricity collection of gathering dust than resistance limits, can only adopt cloth bag collection; The 2nd, as ash-laden gas temperature being down to below 150 ℃, investing higher or limited by place; The 3rd, because include the composition of sulphur in dust flue gas temperature, tool acid dew point, ash-laden gas can only carry out the factors such as isolated by filtration under the higher situation of the above temperature of acid dew point.
Fiberglass needled mat, can be widely used in chemical industry, iron and steel, metallurgy, carbon black, generating, the filtering high-temperature flue gas of the various industrial furnaces such as cement.Be applicable to the various sack cleaners such as pulse dust cleaning and higher speed reverse gas cleaning.Fiberglass needled mat is a kind of rational in infrastructure, the fire resistant filter material of better performances.It is high temperature resistant that it not only has Woven glass cloth, corrosion-resistant, dimensionally stable, and elongation shrinkage factor is minimum, the advantage that intensity is high, and carpet veneer fiber holds filament, three-dimensional micropore structure, porosity is high, little to gas filtration resistance, be a kind of higher speed, efficient high-temperature-resistant filtering material.Compare with other high temperature resistant chemical fibre felt, there is price low, the more high special benefits of heatproof.But its running resistance will be higher than general chemical fibre high-temperature filter material, and filtering accuracy is lower slightly.
For high temperature contaminated air, " the thin composite filtering material of micropore " is the current air filting material in specific environment practicality." the thin composite filtering material of micropore " is to be raw material through polytetrafluoroethylene (PTFE), is puffed to a kind of film with microporosity, and this film is compounded on various fabrics or paper substrates with special process, becomes a kind of novel " the thin composite filtering material of micropore ".This is a kind of desirable filtering material, it has the splendid chemical stability of the intrinsic performance of polytetrafluoroethylene (PTFE), extremely smooth, the extremely low sassafras coefficient that rubs in surface, high-low temperature resistant, can not aging, durable consumer goods use, and it also has microporosity, gas permeability and hydrophobicity.But such filtrate is due to the problem of material itself, and air drag is huge, and price is high, has limited it and applied.
Summary of the invention
For problems of the prior art, the invention provides a kind of basalt fibre snow Neil woven fabric, this woven fabric, in high temperature contaminated air filter process, not only can reduce filtration resistance, and improves air filtration filter effect.
