Problems solved by technology

Since photocatalysts are usually powdery solids or liquid sols, it is necessary to provide a carrier that facilitates photocatalyst attachment; at present, commonly used photocatalyst carriers include activated carbon felt, activated carbon sponge, paper honeycomb, aluminum honeycomb, wire mesh, etc., but these carriers The adhesion to the photocatalyst film is not strong enough, it is easy to fall off, and the service life is short

Embodiment Construction

[0013] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0014] figure 1 A porous ceramic plate photocatalyst carrier is shown, which can be applied to the field of high-efficiency photocatalytic air purification. It has a ceramic plate 1 body, the material of the ceramic plate 1 is cordierite, the porosity is 45%, the micropore diameter is 2-3 μm, the water absorption rate is at least 25%, and the specific surface area is 5-10 square meters per gram, and The thickness h of the ceramic plate 1 is 5 to 20mm, which can improve the scope of application of the ceramic plate 1; the through holes 2 of the same size are evenly distributed on the ceramic plate 1, in order to increase the irradiation area of ​​the photocatalyst by ultraviolet light and the photocatalyst For the contact area with poisonous and harmful gases, the through holes 2 are circular holes, conical holes or polygonal holes, and the number of ho...

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

Technical field: [0001] The invention relates to a photocatalyst carrier, in particular to a porous ceramic plate photocatalyst carrier, which can be applied to the field of high-efficiency photocatalytic air purification. Background technique: [0002] With the continuous improvement of life, people pay more and more attention to their own health. Since people work and live indoors, the requirements for indoor air quality are getting higher and higher. Because the indoor environment is relatively closed, the indoor air quality is relatively poor, and it is easy to breed germs, thereby endangering people's health. [0003] In order to improve indoor air quality, in recent years, people have developed some devices for purifying air quality, such as air purifiers of mechanical filter type, negative ion type, electronic dust collection type and other varieties. However, these models can only purify dust particles and some harmful substances in the indoor air, and it is difficu...
