Description
Technical field
The utility model relates to a kind of warp-knitted spacer fabric, is specifically related to a kind of air filtration snow Neil warp-knitted spacer fabric.
Background technology
Its heart yearn of chenille yarn of the prior art is that raw material twisting forms with acrylic yarn, and camlet is that raw material cuts into short plumage and forms with spun rayon, is widely used in house and spins and knitwear 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 by " coal-smoke pollution " that the industrial revolution of 18th century brings and 19th century oil and auto industry " photochemical pollution " that bring after, it be the 3rd pollution period indicated that modern is just experiencing with " serious PM2.5 type haze air environmental pollution " with Chinese characteristics.Living environment residing for present people is more and more severe, and endless industrial discharged waste gas, the vehicle exhaust be seen everywhere result in 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 dust-proof 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 resistance and the use problem that generally all will consider air cleaner, in case airborne suspended particle impacts to clean area, and ensures filter service life.
Particulate in air is removed technology and is mainly contained mechanical filter, absorption, electrostatic precipitation, anion and plasma method and the filtration of electrostatic electret etc.Mechanical filter generally catches particulate mainly through following 3 kinds of modes: directly tackle, inertial collision, Blang's diffusion mechanism, and to fine particle thing collecting effect, good but windage is large for it, and in order to obtain high purification efficiency, filter core needs fine and closely also to regularly replace.Absorption utilizes the high surface area of material and loose structure to catch particulate pollutant, is easy to blocking, more remarkable for gas pollutant removal effect; Electrostatic precipitation utilizes high-voltage electrostatic field to make gas ionization thus makes dust particles be adsorbed onto collecting method on electrode, though its windage little to larger particles and fiber trapping weak effect, can electric discharge be caused, and cleaning trouble time-consuming, easy generation ozone, forms secondary pollution.The operation principle that anion and plasma method remove indoor particle pollutant is similar, all by making the particle in air charged, coalescent formation larger particles and sedimentation, but in fact particle does not remove, just be attached on neighbouring surface, easily cause airborne dust again.Electrostatic electret filters with 3M " high efficiency electrostatic airstrainer " as representative, adopt and breakthroughly carry permanent electrostatic filter material, be greater than the particulate pollutant of 0.1 micron in effective obstruct air, as dust, soft flocks, pollen, bacterium etc., super-low impedance guarantees air-conditioning stable operation and refrigeration simultaneously.In addition, longer service life is guaranteed in the design of degree of depth appearance dirt.Be used widely 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, the Capital Airport three phase).Traditional standard filter media effectively can remove the particle of more than 10 microns.When the particle diameter of particle is except to 5 microns, during the scope of 2 microns of even sub-micron, efficient mechanical filtration system will become costly, and windage can significantly increase.Filtered by electrostatic electret air filting material, very high capture rate can be reached with lower energy resource consumption, have the advantage of the low windage of electrostatic precipitation simultaneously concurrently, but without the need to the voltage of external volt up to ten thousand, therefore can not ozone be produced, and consist of polypropylene material due to it, easily abandon process.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 use.
Terylene needled felt has more the filtering material of the efficient material of advanced function.General flue-gas temperature, not higher than 150 DEG C, can select the flexible filter materials such as terylene needle punched non-woven fabrics, but industrial temperature is higher than more than 150 DEG C, 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. then select aramid fibre filter bag.One is because these exhaust gas dusts are not suitable for electricity gather dust collection because limiting by ratio resistance, and cloth bag can only be adopted to collect; Two is as ash-laden gas temperature being down to less than 150 DEG C, invests higher or limits by place; Three is that tool acid dew point, ash-laden gas can only carry out the factors such as isolated by filtration under the situation that the above temperature of acid dew point is higher because include the composition of sulphur in dust flue gas temperature.
Fiberglass needled mat, can be widely used in chemical industry, iron and steel, metallurgical, carbon black, generating, the filtering high-temperature flue gas of the various industrial furnace such as cement.Be applicable to the various sack cleaner 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, and porosity is high, little to gas filtration resistance, be a kind of higher speed, efficient high-temperature-resistant filtering material.Compared with other high temperature resistant chemical fibre felt, there is price low, the more high special benefits of heatproof.But its running resistance is 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 at present at the air filting material of specific environment practicality." the thin composite filtering material of micropore " is raw material through polytetrafluoroethylene (PTFE), is puffed to a kind of film with microporosity, is compounded on various fabric or paper substrates by this film special process, become 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), surperficial extremely smooth, the extremely low sassafras coefficient that rubs, 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, limits it and apply.
