Abstract
The utility model relates to a photocatalyst carrier adopting a porous ceramic plate, and can be applied to the field of efficient photocatalysis air purification. The photocatalyst carrier comprises a ceramic plate body, wherein through holes, which are the same in size, 30 to 60 per square inch in quantity, and 30 to 60 percent in area, are uniformly distributed on the ceramic plate; the thickness h of the ceramic plate is 5 to 20 mm; and the through holes are round holes, conic holes or polygonal holes. The photocatalyst carrier is high in appetency and high-temperature resistant; and a photocatalyst thin film formed by sintering the photocatalyst carrier on the ceramic plate is high in adhesive power, less susceptible to flaking off, water washing resistant, and long in service life. The photocatalyst carrier adopting the porous ceramic plate has the advantages that the contact area between photocatalyst and toxic or harmful gases is greatly enlarged, and the irradiation area of ultraviolet light on the photocatalyst is also enlarged, so as to achieve an efficient light-catalyzed reaction effect, and reduce wind resistance.
Description
Technical field:
The utility model relates to a kind of optical catalyst carrier, relates in particular to a kind of porous ceramic plate optical catalyst carrier, can be applicable to the high efficiency photocatalysis air purification field.
Background technology:
Along with the continuous improvement of life, people more and more pay attention to the health status of self, because people's work and life all indoor, therefore, require increasingly high for indoor air quality.Because indoor environment is relatively sealed, therefore cause IAQ poor, grow germ easily, thereby the harm people's is healthy.
In order to improve IAQ, in recent years, people develop the device of some quality that are used to purify air, like the air purifier of kinds such as mechanical filter formula, anion formula, electronic dust-collecting type.Dust particle during yet these types only can purify the air of a room and part harmful substance, the poisonous and hazardous volatile organic contaminant (VOC) that pathogen, virus, microorganism and interior decoration are caused is difficult to thorough elimination.And filtering material can lose effect and produce secondary pollution after absorption is saturated.
In order to develop effective air cleaning unit, it is found that photocatalyst.Photocatalyst is a kind of nano level metal oxide materials (titanium dioxide is more commonly used); It coats substrate surface, under the effect of light, produces strong catalytic degradation function; The toxic and harmful in the air of degrading effectively; Can effectively kill various bacteria, and can the toxin that bacterium or fungi discharge be decomposed and harmless treatment, function such as also possess extremely strong sterilization, deodorizing, mildew-resistant, anti-fouling and self-cleaning simultaneously, purify air.Because photocatalyst normally presents pulverulent solids or lyosol, therefore, need provide and be convenient to the carrier that photocatalyst adheres to; At present, optical catalyst carrier commonly used has activated carbon felt, active carbon sponge, paper wasp nest, aluminium honeycomb, woven wire etc., but these carriers strong inadequately for the adhesive force of photo-catalyst film, be prone to come off, service life is short.
Summary of the invention:
The utility model technical problem to be solved is, provide a kind of to the photocatalyst strong adhesion, support the big porous ceramic plate optical catalyst carrier of area that area is big, accept light irradiation.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme: a kind of porous ceramic plate optical catalyst carrier can be applicable to the high efficiency photocatalysis air purification field.Have the ceramic wafer body, be uniform-distribution with on the said ceramic wafer size identical, hole count is 30～60 hole/square inches, perforated area is 30～60% open-work.
In order to make ceramic wafer adapt to different application environments, further, the thickness h of said ceramic wafer is 5～20mm.
In order to increase ultraviolet light to the irradiated area of photocatalyst and the contact area of photocatalyst and toxic and harmful, more further, said open-work is circular hole, conical bore or polygonal hole.
Compared with prior art; The usefulness of the utility model is: this porous ceramic plate optical catalyst carrier affinity is strong; High temperature resistant; The photo-catalyst film strong adhesion that sintering forms on ceramic wafer, difficult drop-off, water-fastly wash, long service life, and this porous ceramic plate optical catalyst carrier not only increased the contact area of photocatalyst and toxic and harmful greatly, also increased the irradiated area of ultraviolet light to photocatalyst simultaneously greatly; Thereby can obtain light-catalyzed reaction effect efficiently, and windage is also very little.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model porous ceramic plate photocatalyst carrier structure sketch map.
Among the figure: 1, ceramic wafer; 2, open-work.
The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in detail:
A kind of porous ceramic plate optical catalyst carrier shown in Figure 1 can be applicable to the high efficiency photocatalysis air purification field.Have ceramic wafer 1 body, said ceramic wafer 1 material is a cordierite, and the porosity is 45%; Micropore size is for being 2～3 μ m, and water absorption rate is at least 25%, and specific area is 5～10 meters squared per gram; And the thickness h of said ceramic wafer 1 is 5～20mm, can improve the scope of application of ceramic wafer 1; Be uniform-distribution with the identical open-work 2 of size on the said ceramic wafer 1; In order to increase ultraviolet light to the irradiated area of photocatalyst and the contact area of photocatalyst and toxic and harmful; Said open-work 2 is circular hole, conical bore or polygonal hole; And hole count is 30～60 hole/square inches, and perforated area is 30～60%.
This porous ceramic plate optical catalyst carrier has huge, coarse surface area; Can support the nano TiO 2 photocatalyst more, more firmly; Like this; Increased greatly ultraviolet light to the irradiated area of photocatalyst, also increased the contact area of photocatalyst and toxic and harmful greatly simultaneously, thereby obtain light-catalyzed reaction effect efficiently; Adopt nano TiO 2 colloid (about the about 15nm of particle diameter) coating as photocatalyst, photocatalytic activity is high; Because ceramic wafer 1 material is a cordierite; Carrier and photocatalyst (titanium dioxide) belong to inorganic oxide together; Both affinity is strong, and porous ceramic plate is high temperature resistant, can be under 305～605 ℃ with the photocatalyst sintering on its surface; Therefore very strong, the difficult drop-off of the adhesive force of the photo-catalyst film that sintering forms on the porous ceramic plate carrier, water-fastly wash, long service life, windage is little.
During utilization; The porous ceramic plate optical catalyst carrier that is coated with photocatalyst is made into the high efficiency photocatalysis air purifier, and its operation principle is that photocatalyst is under the irradiation of ultraviolet light; Produce electron hole pair (e-/h+) owing to having absorbed luminous energy; These holes can migrate to the surface rapidly to (photocarrier), and activate H2O and the O2 of its surface attachment and produce hydroxyl radical free radical OH and superoxide radical O2-, and the extremely strong active free radical of these two kinds of oxidisability can be rapidly and the hydrocarbon reaction of the photocatalyst surface bacterium, virus and the macromolecule that adhere to; Generate harmless CO2 and water, have advantage energy-conservation, long-acting, non-secondary pollution.
It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
