Description

technical field [0001] The invention relates to an air purification method and a device thereof. Background technique [0002] At present, most of the air purification technology still stays on the simple filtration technology, which only filters the dust and suspended solids, and cannot purify the organic pollution. With the enhancement of people's awareness of environmental protection, people's requirements for air quality are getting higher and higher, which requires us to provide a technology that can effectively remove organic pollution in the air. [0003] Currently, the most promising technology for removing organic pollutants from the air is photocatalyst technology. Photocatalyst [Photocatalyst] is a compound word of light [Photo=Light] + catalyst (catalyst) [catalyst]. Photocatalyst is a general term for photo-semiconductor materials with photocatalytic function represented by nano-scale titanium dioxide. It is currently the most ideal material for indoor environ...
