In one embodiment, the second tunic is aperture at the non-woven fabrics of 0.2-0.4 micron or filter paper.In another embodiment, the first tunic by the two-layer nonwoven of aperture between 5-10 micron, and is filled NACF in-between and forms.The specific area of active carbon is very large, is conducive to the dust in absorbed air.The aperture of the second tunic is less than the particle diameter of PM2.5, therefore, it is possible to effectively filter PM2.5.
By arranging third layer film, air purifying filter core of the present utility model is made also to be applicable to the higher environment of pollution gas concentration, such as automotive interior, finishing house soon.
In one embodiment, described third layer film adopts string braiding to form, and is wherein provided with rectangle arranged in parallel or square chamber, for holding adsorbent and/or catalyst.In chamber, be filled with the capsule that non-woven fabrics is made, micron or nano level adsorbent and/or catalyst are placed in capsule.Can be protected adsorbent and/or catalyst by capsule and chamber, prevent again its directly and contacting external air cause premature failure, thus to extend working time.
In one embodiment, the first tunic is in outermost layer, and the second tunic is in innermost layer, and third layer film is between the first tunic and the second tunic.The thickness of third layer film is greater than the thickness of the first tunic and/or the thickness of the second tunic.Preferably, the thickness of third layer film is greater than the thickness of the first tunic and the thickness sum of the second tunic.
In one embodiment, air purifying filter core is in the configuration that folds, and folding is deeply between 2-5 centimetre.
In this application, PM2.5 refers to that equivalent aerodynamic diameter is less than or equal to the particle of 2.5 microns, and it is very large to the harm of human body and environment.
Compared with prior art, the utility model has the advantage of, air purifying filter core comprises the first tunic for Chalk-dust filtering, sterilization, for filtering second tunic of PM2.5, also comprises the third layer film for removing pernicious gas.In addition, first tunic is in outermost layer, second tunic is in innermost layer, third layer film is between the first tunic and the second tunic, make first to remove according to air purifying filter core of the present utility model the pollutant that in air, particle diameter is maximum, finally remove the minimum pollutant of particle diameter, help make every skim all can farthest play respective function, the overall power of air purifying filter core is maximized.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, stacked multi-layer air filter membrane is comprised according to air purifying filter core 10 of the present utility model, particularly comprise the first tunic 11 for adsorption of dust and sterilization and the second tunic 12 for filtering PM2.5 of putting inside the first tunic 11, and between the first tunic 11 and the second tunic 12, be also provided with the third layer film 13 for removing pollution gas.
As shown in Figure 2, the structure of the first tunic 11 is two-layer nonwoven 21,22 coating active Carbon fibe 23.The aperture of non-woven fabrics 21,22 is preferably between 5-10 micron.The two-sided compound nonwoven cloth NACF that first tunic 11 such as can select Qinhuangdao Zi Chuan Carbon fibe Co., Ltd to produce.
Second tunic 12 selects aperture at the non-woven fabrics of 0.2-0.4 micron or filter paper usually.Because the grain size of the PM2.5 in air is at 2.5 microns, therefore the second tunic 12 effectively can remove PM2.5.Preferably, can also on the second tunic 12 load bactericide, thus while filtration PM2.5, can also sterilization.The trade mark that second tunic 12 such as can use Guangzhou three to stand the production of non-woven fabrics Co., Ltd is the Air Conditioning filter cloth of highly dense type 3LK130, and the aperture of this filter cloth is at 0.3 microns.
Still as shown in Figure 1, between the first tunic 11 and the second tunic 12, the third layer film 13 that string is woven into also is provided with, for removing pernicious gas in air.Described string has antibacterial and deodouring and the firm advantage such as wear-resisting, can adopt the fibers such as bamboo, cotton, fiber crops, preferred bamboo fibre.The thickness of described third layer film 13 is greater than the thickness of described first tunic 11 and/or the thickness of described second tunic 12, and more preferably the thickness of described third layer film 13 is greater than the thickness of described first tunic 11 and the thickness sum of described second tunic 12.The particle diameter of PM2.5 is much smaller than dust in air, this set is actually and first removes the pollutant that in air, particle diameter is maximum, finally remove the minimum pollutant of particle diameter, contribute to making every skim all can farthest play respective function, the overall power of air purifying filter core is maximized.
As shown in Figure 3, in third layer film, be provided with cuboid arranged in parallel or square chamber 31, for holding adsorbent and/or catalyst.The width of preferred described chamber 31 and length are 1 ~ 2cm, and height is 0.5 ~ 1cm.
Described adsorbent can be nano level MnO
2, CuO powder etc., catalyst can be nano level TiO
2, one or more in Pt and Au.These adsorbents can produce chemisorbed with pollutants such as the benzene,toluene,xylene of air, polycyclic aromatic hydrocarbon, hydrogen sulfide, sulfur dioxide and nitrogen oxide, thus it are removed from air.And under the natural environment that catalyst can be lived usually people, formaldehyde, carbon monoxide etc. are catalyzed into harmless material thus it is removed from air.
In chamber 31, be filled with the capsule 32 that non-woven fabrics is made, adsorbent and/or catalyst are placed in capsule 32.In third layer film 13, be covered with braiding hole, can absorb rapidly and transpiring moisture, gas can by the aperture on capsule 32, at third layer film 13 and circulate between the first tunic 11 and the second tunic 12.
In process of production, first according to predetermined order, the first tunic 11 is arranged on skin, the second tunic 12 is arranged on internal layer, and third layer film 11 is arranged between first and second tunic.Then, use adhesive hot pressing to be combined with each other, form the air purifying filter core 10 had except PM2.5, sterilization, scrubbing metachromia gas.Preferably on the contact surface of third layer film 13 and the first tunic 11 and the second tunic 12, be provided with intermeshing prismatic projection (not shown on figure), to make the combination between trilamellar membrane tightr.The width of prismatic projection and can be highly 1 ~ 2mm, is obtained by the punching press of routine or hot pressure method.Finally, air purifying filter core 10 is folded, cuts into corresponding size.In one embodiment, air purifying filter core 10 is in the configuration that folds, and the dark L of folding is between 2-5 centimetre.The configuration that folds of air purifying filter core 10 is conducive to reducing its volume, easy to use.
Although be described the utility model with reference to preferred embodiment, when not departing from scope of the present utility model, various improvement can be carried out to it and parts wherein can be replaced with equivalent.Especially, only otherwise there is structural hazard, the every technical characteristic mentioned in each embodiment all can combine in any way.The utility model is not limited to specific embodiment disclosed in literary composition, but comprises all technical schemes fallen in the scope of claim.
