Abstract

A photo catalytic air treater with high adsorbability is composed of casing of treater, snake-shaped ultraviolet lamp, light-shielding glass fiber layer, metallic plate sieve, granular adsorption material, fibrous stack carrying photocatalyst with high adsorbability, middle glass plate with the said photocatalyst sintered on its surface, and air inlet fan. The said photocatalyst consists of surficial activated carbon layer A whose volume content of TiO2 is less than 50%, activated carbon layer B whose volume content of TiO2 is greater than 50%, activated carbon layer B whose volume content of TiO2 is greater than 50%, nanometre-thickness TiO2 rutile layer as transition layer, and main body of carrier.

Description

technical field [0001] The invention relates to an air processor using a material with high adsorption property and high photocatalytic conversion efficiency for organic matter, in particular to a photocatalytic air processor with high adsorption property. Background technique [0002] Using semiconductor catalyst materials to be excited by ultraviolet light or visible light can generate high-energy charge electron-hole pairs. With the participation of oxygen or water, pollutants, microorganisms, organic substances, bacteria, etc. adsorbed on the catalyst surface can be oxidized or reduced, or transformed. Or degradation, so as to achieve the purpose of purifying the air, and the oxygen and trace moisture in the air just provide the conditions for this kind of reaction. [0003] Wide-bandgap semiconductor photocatalysts require the use of excitation light sources excited by ultraviolet light. For TiO 2 Excitation requires a UV light source with λ°≤380nm. This feature just...
