Description
Technical field
This utility model relates to a kind of drainage screen, is specifically related to a kind of photo-catalytic filtering screen.
Background technology
The mankind spend in indoor more than at least 70% time, and the time that urban population is spent in indoor has exceeded 90%, and especially infant and the old and the weak crippled is longer in the indoor time.But the concentration of indoor air pollutants (common such as toluene, benzene, formaldehyde etc.) is usually 2～5 times of outdoor pollutant levels, it is dozens or even hundreds of times of outdoor pollutant in some cases.Since the seventies, occur in that so-called " harmful building syndrome (SickBuildingSyndrome, SBS) " in developed country, it is simply that the performance of room air pollution potential problems.Developing rapidly along with socioeconomic, the pursuit of high-quality life is improved constantly by modern, and Chinese real estate development is swift and violent, brings the flourish of building decorating industry.Current indoor pollutes the public health problem that the various health problems caused have become prominent.
Photocatalyst is the general name of a kind of photosemiconductor material with photo-catalysis function with Nano titanium dioxide as representative, and it coats substrate surface, under the effect of light, produces strong catalytic degradation function: toxic and harmful in air of effectively degrading；Can effectively kill various bacteria, and the toxin that can antibacterial or fungus be discharged decomposes and harmless treatment；It is also equipped with the functions such as deodorization, anti-soil, purification air simultaneously.In prior art, photocatalyst is typically constituted photocatalyst body using pore type pottery or aluminum datum hole plate as substrate, although pore type pottery and the application of aluminum datum hole plate are relatively extensively, but price is higher, and photocatalyst absorbability and venting capability general.
Utility model content
For problem above, this utility model provides a kind of photo-catalytic filtering screen, employing has certain thickness glass fiber mesh, and matrix surface spreads attached active carbon layer, advantage is that adsorptivity is strong, good permeability, sponge photocatalyst layer area is big and adhesive force is strong, breathe freely, and cheap, can effectively solve the problem in technical background.
To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of photo-catalytic filtering screen, including filter screen base material and mesh, described mesh and filter screen base-material surface inclined 10-20 degree, described filter screen base material uses glass fiber mesh, and the described positive and negative surface of filter screen base material scribbles titanium deoxid film, and described titanium deoxid film surface-coated has layer of active carbon layer, scribble sponge photocatalyst layer on described active carbon layer, in described mesh, be provided with filter course.
Further, by folding, HEPA filter screen that the number of plies is 50-60 layer is stacked to be formed described filter course.
Further, the thickness of described filter course is 1-2mm.
Further, described titanium deoxid film is provided with 1-5 layer.
Further, the thickness of described filter screen base material is 4-6mm.
The beneficial effects of the utility model:
This utility model uses has certain thickness glass fiber mesh, and matrix surface spreads attached active carbon layer, advantage is that adsorptivity is strong, good permeability, sponge photocatalyst layer area is big and adhesive force is strong, breathe freely, and it is cheap, have and cut out conveniently, reconfigurable, decomposition efficiency is high, preparation cost is low, applied range, drainage screen has high de-agglomeration efficiency, low preparation cost, the drainage screen of the photocatalyst material of applied range, mesh tilts, filter screen is made to have bigger adjustment space, this utility model is used for family, office, medical treatment, food and drink, market, vehicle etc., there is higher practical value.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram.
Fig. 2 is the structural representation of this utility model filter screen base material.
Figure is numbered: 1-filter screen base material, 2-mesh, 3-titanium deoxid film, 4-active carbon layer, 5-sponge photocatalyst layer, 6-filter course.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As depicted in figs. 1 and 2, a kind of photo-catalytic filtering screen, including filter screen base material 1 and mesh 2, described mesh 2 tilts 10-20 degree with filter screen base material 1 surface, described filter screen base material 1 uses glass fiber mesh, the described positive and negative surface of filter screen base material 1 to scribble titanium deoxid film 3, and described titanium deoxid film 3 surface-coated has layer of active carbon layer 4, scribble sponge photocatalyst layer 5 on described active carbon layer 4, in described mesh 2, be provided with filter course 6.
On above-described embodiment preferably, described filter course 6 is formed by the HEPA filter screen that the folding number of plies is 50-60 layer is stacked.
On above-described embodiment preferably, the thickness of described filter course 6 is 1-2mm.
On above-described embodiment preferably, described titanium deoxid film 3 is provided with 1-5 layer.
On above-described embodiment preferably, the thickness of described filter screen base material 1 is 4-6mm.
Based on above-mentioned, this utility model uses has certain thickness glass fiber mesh, and matrix surface spreads attached active carbon layer, advantage is that adsorptivity is strong, good permeability, sponge photocatalyst layer area is big and adhesive force is strong, breathe freely, and it is cheap, have and cut out conveniently, reconfigurable, decomposition efficiency is high, preparation cost is low, applied range, drainage screen has high de-agglomeration efficiency, low preparation cost, the drainage screen of the photocatalyst material of applied range, mesh tilts, filter screen is made to have bigger adjustment space, this utility model is used for family, office, medical treatment, food and drink, market, vehicle etc., there is higher practical value.
