Compared with the prior art, the utility model has the advantages of absorption cabin air filter absorption efficiency, filtration efficiency, dust containing capacity have been improved.
Description
Technical field
The utility model relates to a kind of air cleaner cartridge, relates to especially a kind of composite reactive carbon fiber air-conditioningFilter core.
Background technology
At present, filter core of automotive air-conditioner can be divided into single-action cleaner and activated carbon composite filtrator substantially. Single-action filteringDevice be by multi-layer nonwoven fabrics by the in addition fixing cleaner forming of frame of paper folding form, there is filtering solid particlesEffect, effectively reduces the indoor concentration of solid particles of riding; Composite activated carbon cleaner is that multi-layer nonwoven fabrics is added with powderyOr the fixing cleaner forming of in addition frame that forms of granule activated carbon, except thering is effect of filtering particle, alsoCan adsorb the pernicious gas such as formaldehyde, toluene, be the direction of high-efficient air cleaner development.
There is following problem in composite active carbon air conditioner filter element: powdery, granule activated carbon specific area are relatively little,The shortcomings such as adsorption efficiency is lower, and the rate of adsorption is little, and adsorbance is little, the service life of greatly reducing air-conditioning filter cleaner.Powdery or graininess cleaner cause composite active carbon air conditioner filter element thickness larger simultaneously, and restricting to a certain extent it shouldWith, under equal volume, effective filtration area is lower, and particle dust containing capacity reduces, and causes replacing air-conditioning filter cleaner frequent,Increase use cost.
Chinese utility model patent CN201482486U discloses a kind of volatile organic matter (VOCs) waste gas and has inhaledThe attached NACF filter core of using, this filter core comprises cylindric inner framework and cylindric outer skeleton, in inner frameworkWith interval is wound around active carbon fiber felt and steel wire between outer skeleton, to reduce operating cost, to improve active carbon fibreDimension felt adsorption efficiency and life-span. But this utility model is directly by being wrapped in active carbon fiber felt in cylindric internal layer boneFrame, does not have preposition coarse filtration layer, and the particle of the different pollutant of particle diameter, all by while adsorption filtration, easily causes filterCore blocks.
Utility model content
The purpose of this utility model is exactly to provide a kind of compound work in order to overcome the defect that above-mentioned prior art existsProperty carbon fiber air conditioner filter element, utilize sandwich construction filter course filter core to replace individual layer active carbon fiber felt filter course, improveAbsorption air conditioner cleaner adsorption efficiency, filter efficiency, dust containing capacity, reached and extended on-board air conditioner filter elementService life.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of composite reactive carbon fiber air conditioner filter element, comprises multi-layer nonwoven fabrics filter course and acf layer, its spyLevy and be, described filter core comprise the nonwoven first filter layer that sets gradually along airflow direction, nonwoven filter bed of essence,Activated carbon fiber adsorption layer and nonwoven supporting layer.
Described nonwoven filter course by melt spraying non-woven fabrics, spun-bonded non-woven fabrics, needle punched non-woven fabrics, spunlace non-woven cloth orOther forms form one or more compositions of fiber.
Described activated carbon fiber adsorption layer by viscose glue base, phenolic aldehyde base, asphaltic base, polyacrylonitrile base, PVA-based,One or more compositions of polyvinylidene chloride base, poly-phthalimide base, polystyrene-based and natural plant fibre base.
Described acf layer is that the capable orientation of activated carbon fiber or non-directional are arranged.
Described activated carbon fiber adsorption layer is arranged between described nonwoven filter bed of essence and nonwoven supporting layer, formsStable sandwich structure;
Each layer by heat bonding, ultrasonic bonding, adhesive is bonding or other forms are bonding.
Described nonwoven first filter layer is selected the nonwoven with intensity is large, fiber is thicker.
Described nonwoven filter bed of essence selects that fiber is thin, the less nonwoven in aperture.
Described nonwoven supporting layer is selected the nonwoven with intensity is large, fiber is thicker.
Described activated carbon fiber adsorption layer is arranged by preparing activated carbon long filament again, or by described activated carbon fiberMake net, felt, paper, woven fabric, nonwoven or other forms, then activate and make activated fiber layer.
Compared with prior art, advantage of the present invention:
One, filtration resistance is little, and pernicious gas adsorbance is large, and the pernicious gas rate of adsorption is high, extends cleaner productService life.
Two, activated carbon fiber layer thickness is little, can dwindle paper folding distance, improves effective filtration area, improves cleanerParticle dust containing capacity.
Brief description of the drawings
By describing in more detail the present invention referring to accompanying drawing, can understand better the utility model below,Principle, feature and advantage.
Fig. 1 is longitudinal cross-section of the present utility model schematic diagram;
In figure, 1. nonwoven first filter layer, 2. nonwoven filter bed of essence, 3. activated carbon fiber adsorption layer, 4. nonwovenCloth supporting layer.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and useful technique effectClearer, below with reference to accompanying drawing and multiple embodiment, the utility model is carried out further in detailDescribe in detail bright. Should be appreciated that specific embodiment described herein is only for explaining the utility model, and notFor limiting protection domain of the present utility model.
As shown in Figure 1, described composite reactive carbon fiber air conditioner filter element is made up of 4 layers of structure, according to circulation of air sideTo comprising that successively nonwoven first filter layer 1, nonwoven filter bed of essence 2, activated carbon fiber adsorption layer 3 and nonwoven supportLayer 4. By nonwoven described above, one or more form described nonwoven first filter layer 1, preferably, and selection intensityGreatly, nonwoven that fiber is thicker, nonwoven first filter layer 1, in order to protect nonwoven filter bed of essence 2, improves filter core simultaneouslySurface strength, stretch bending intensity and deflection, the preliminary interception larger particles of filtering. Described nonwoven filter bed of essence 2By nonwoven described above, one or more form, and preferably, select fiber thinner, and aperture is less, to tiny solidBody particle carries out isolated by filtration, is filter bed of essence; Described nonwoven filter bed of essence 2 is arranged at according to circulation of air directionAfter described nonwoven first filter layer 1. Described activated carbon fiber adsorption layer 3 by NACF described above a kind of orSeveral compositions, after being arranged at described nonwoven filter bed of essence 2, adsorb poisonous, You Haiji according to circulation of air directionGas with foreign flavor; One or more compositions of described nonwoven supporting layer 4 nonwoven described above, preferably, select strongThe nonwoven that degree is large, fiber is thicker, improves cartridge surface intensity, stretch bending intensity and deflection, to activated carbon fibreDimension layer forms protection, reduces circulation of air resistance simultaneously.
