This practical compound high -efficient HEPA filter screen filters through adopting multiple filter screen, and the clearance of the filter screen of being convenient for has reduced maintenance cost, when having improved the filter effect, improved the bulk strength and the rigidity of filter screen, lengthened HEPA filter screen life, reduced the filtration cost, the bacterium is killed to compound cold catalyst of silver or the photocatalyst activated carbon fiber felt of carrying of this product simultaneously, the mould, virus is adsorbed and is decomposed peculiar smell, harmful gas such as formaldehyde, benzene, xylol, toluene, TVOC.
Description
Technical field
The utility model relates to a kind of filter, specifically, relates to a kind of composite highly effective HEPA filter screen.
Background technology
HEPA (HighefficiencyparticulateairFilter), the Chinese meaning is high efficiency particle air filter, reach the screen pack of HEPA standard, 99.7% is reached for the efficient of 0.1 micron and 0.3 micron, the feature of HEPA net is that air can pass through, but tiny particulate cannot pass through.It can reach more than 99.97% to the particle removal efficiency that diameter is more than 0.3 micron (1/200 of hair diameter), is the most effective filtering mediums of pollutant such as smog, dust and bacterium.HEPA divides PP filter paper, glass fibre, compound PPPET filter paper, melt-blown terylene non-woven fabric and melt-blown glass fibre five kinds of materials.Feature: windage is little, dust containing capacity is large, and filtering accuracy is high, can need to be processed into various sizes and shape according to client, is applicable to different types and uses.
The effect of the filtration of particulate matters of HEPA is obviously, if use its filter cigarette, the effect of so filtering almost can reach 100%, because the particle size in cigarette is between 0.5-2 microns, cannot pass through HEPA filter membrane.The clean usefulness of filter of HEPA high efficiency particle screen is directly proportional to its surface area.The HEPA high efficiency particle screen of air purifier is multilayer folding, and after launching, area ratio increases about 14.5 times when folding, and it is very outstanding to filter clean usefulness.
But HEPA can only filtration of particulate matters, inoperative to organic filtration, and HEPA filters the particle of 0.3 micron to 10 microns, has dust in air, the bulky grain things such as hair, blocking HEPA filter paper, lowers service life and result of use
Utility model content
For above-mentioned deficiency of the prior art, the utility model provides one to have good filter effect, sterilization, adsorption-decomposition function peculiar smell, pernicious gas, extends the composite highly effective HEPA filter screen that HEPA nets service life.
Technical solution adopted in the utility model is:
A kind of composite highly effective HEPA filter screen, comprise outer layer metal screen frame frame, the top of described wire netting frame inner surface is provided with ground floor prefiltering net, and described ground floor prefiltering net bottom is provided with second layer HEPA filter screen; Described second layer HEPA filter screen bottom is provided with carries silver-colored cold catalyst.
Described wire netting framework comprises outer screen and inner screen, and described outer screen is connected by connection network with inner screen.
The aperture of described inner screen is less than the aperture of outer screen.
The aperture of described inner screen is 1/1 to two/3rd of outer screen aperture.
The sieve aperture of described inner screen and the sieve aperture of described outside screen cloth are crisscross arranged.
Described HEPA filter screen thickness is 2-100 millimeter.
Within described year, silver-colored cold catalyst thickness is 2-100 millimeter.
The beneficial effect of the utility model hinge structure:
This practical composite highly effective HEPA filter screen, by adopting multi-filtering net to filter, being convenient to the cleaning of screen pack, reducing maintenance cost; While improve filter effect, improve bulk strength and the rigidity of screen pack, extend HEPA filter screen service life, reduce filtration cost.

Detailed description of the invention
Referring to drawings and Examples, the utility model is described in detail:
Accompanying drawing 1 is known, and a kind of composite highly effective HEPA filter screen, comprises outer layer metal screen frame frame, and the top of described wire netting frame inner surface is provided with ground floor prefiltering net 1, and described ground floor prefiltering net 1 bottom is provided with second layer HEPA filter screen 2; Described second layer HEPA filter screen 2 bottom is provided with carries silver-colored cold catalyst 3 or replaces carrying silver-colored cold catalyst with photocatalyst activity Carbon fibe felt.Described wire netting framework comprises outer screen 4 and inner screen 5, and described outer screen 4 is connected by connection network 6 with inner screen 5.The aperture of described inner screen 5 is less than the aperture of outer screen 4.The aperture of described inner screen 5 is 1/1 to two/3rd of outer screen 4 aperture.Described inner screen 5 is crisscross arranged with the sieve aperture of outside screen cloth 4.Described HEPA filter screen 2 thickness is 2-100 millimeter.Described year silver-colored cold catalyst or photocatalyst activity Carbon fibe felt 3 thickness are 2-100 millimeter.This practical composite highly effective HEPA filter screen, the three layer filtration net of inside is wrapped in wherein by outer field wire netting framework, and three layer filtration net is mutually independent, and is convenient to cleaning and changes.
This practical composite highly effective HEPA filter screen, by adopting multi-filtering net to filter, being convenient to the cleaning of screen pack, reducing maintenance cost; While improve filter effect, improve bulk strength and the rigidity of screen pack, extend HEPA filter screen service life, reduce filtration cost.
This practical composite highly effective HEPA filter screen, ground floor is prefiltering net material is cotton fiber net, ensures that air effectively passes through, removes large the thing such as dust and hair simultaneously; The second layer is HEPA filter screen, and material is HEPA folded filter paper, removes the heavy little particle bacterium, virus etc. to 0.3 micron of air; Third layer is for carrying silver-colored cold catalyst or photocatalyst activity Carbon fibe felt, mainly adsorb peculiar smell, formaldehyde, benzene, dimethylbenzene, TVOC etc. pernicious gas, plays sterilization, adsorption-decomposition function peculiar smell, pernicious gas effect, outermost layer kalamein net, fixed position, sturdy and durable, coarse filtration is carried out to bulky grain and long fibrous materials simultaneously.
This practical composite highly effective HEPA filter screen, ensures that in installation process ground floor is that prefiltering net is arranged on outside, otherwise cannot play the effect of filtration.
This practical composite highly effective HEPA filter screen, is widely used in having in the automobile of seal cavity, train and aircraft inlet channel, needs to arrange according to difference.
The above is only preferred embodiment of the present utility model, not does any pro forma restriction to structure of the present utility model.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all belong within the scope of the technical solution of the utility model.
