Titanium dioxide photocatalytic reactor

Abstract

The invention discloses a titanium dioxide photocatalytic reactor, which comprises a light guide film, a channel arranged on the inner side of the light guide film, and a plurality of light guide members arranged in the channel, wherein at least a light source member is arranged at the end portion of the light guide film, a light source emitted by the light source member extends along the channel,the plurality of the light guide members are distributed in the channel in a staggered manner so as to project at least part of the light source emitted by the light source member on the light guidemembers, at least a reaction point is arranged on one side, close to the light source member, of the light guide member, an overlapping area is formed by the overlapping area of the surface of the reaction point, the light source and a catalyzed object, and the overlapping area can conduct a photocatalytic reaction.

Description

technical field [0001] The invention relates to a photocatalytic reactor, in particular to a titanium dioxide photocatalytic reactor. Background technique [0002] The principle of photocatalysis is based on the redox ability of photocatalysts to purify pollutants under ultraviolet irradiation. Photocatalytic purification technology has the advantages of deep oxygen at room temperature, less secondary pollution, low operating cost, and the possibility of using sunlight as a reaction light source. Therefore, photocatalysis is especially suitable for the purification of indoor volatile organic compounds, and has shown great application in deep purification. potential. Common photocatalysts are mostly metal oxides and sulfides, such as Tio2, ZnO, CdS, WO3, etc. Among them, Tio2 has the best comprehensive performance and is the most widely used. Tio2 has good photocorrosion resistance and catalytic activity, and its performance is stable. , cheap and easy to obtain, non-toxic ...

AI Technical Summary

Problems solved by technology

[0003] The traditional photocatalytic reaction to decompose organic matter has no selectivity, and the loaded catalytic material itself will also be decomposed. Once the catalytic particles fall off, the material will fail; The reaction area is small, the catalytic effect is too weak, and this leads to incomplete oxidation reaction, which easily produces other harmful substances
