Problems solved by technology

The bottleneck of the existing photocatalyst air purification technology lies in the low quantum efficiency of the catalytic reaction, that is, the ratio of the effective electrons or holes generated to the incident photons is low, and there is a defect of low light source utilization. Improving the quantum efficiency of the photocatalytic reaction is an improvement. The key to photocatalyst air purification technology
In the existing photocatalyst air purification equipment, improving the photocatalyst reaction efficiency and ensuring the air flow are a pair of unsolvable contradictions, and we can only choose one of the two.
At present, in the existing products, the structure of the photocatalyst carrier (the photocatalyst material is loaded on the photocatalyst carrier) usually adopts two layout schemes: perpendicular to the light and parallel to the vertical arrangement: 1. The photocatalyst support adopts the layout perpendicular to the light At this time, the ph

Description

technical field [0001] The invention relates to an air purification module, in particular to a photocatalyst air purification module and an air purification device composed of the same. Background technique [0002] Photocatalyst material is a general term for a class of photocatalytic semiconductors represented by TiO2, which can excite electrons under light irradiation conditions, and the formed electrons and holes react with oxygen and water molecules in the air to form highly oxidizing Hydroxyl free radicals can kill bacteria in the air and degrade organic pollutants to achieve the purpose of purifying the air. The bottleneck of the existing photocatalyst air purification technology lies in the low quantum efficiency of the catalytic reaction, that is, the ratio of the generated effective electrons or holes to the incident photons is low, and there is a defect of low utilization rate of the light source. Improving the quantum efficiency of the photocatalytic reaction is ...
