Abstract

The invention discloses a porous ceramic plate photocatalyst carrier which can be applied to the high-efficiency photocatalytic air cleaning field. The carrier has a ceramic plate body, wherein the ceramic plate body is uniformly distributed with through holes with a same size, the hole number of 30-60 holes/square inch and the hole area of 30-60%; the thickness h of the ceramic plate is 5-20mm; and the through holes are circular holes, conical holes or polygonal holes. The porous ceramic plate photocatalyst carrier has the characteristics of strong affinity and high temperature resistance, photocatalyst films sintered on the ceramic plate have the advantages of strong adhesion, difficult shedding, washing resistance and long service life, and the porous ceramic plate photocatalyst carrier allows the contact area of a photocatalyst and poisonous and harmful gases to be substantially increased and the irradiation area of the photocatalyst by ultraviolet lights to be substantially increased, so a high-efficiency photocatalytic reaction effect is obtained, and the wind resistance is very small.

Description

A kind of porous ceramic plate optical catalyst carrier
Technical field:
The present invention relates to a kind of optical catalyst carrier, relate 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:
Technical problem to be solved by this invention 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 present invention realizes 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; Usefulness of the present invention 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 present invention is further specified.
Fig. 1 is a kind of porous ceramic plate photocatalyst carrier structure of the present invention sketch map.
Among the figure: 1, ceramic wafer; 2, open-work.
The specific embodiment:
Describe the present invention below in conjunction with the accompanying drawing and the specific embodiment:
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 preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
