Abstract

The invention discloses an integral type photo-catalytic lamp for air purification. The integral type photo-catalytic lamp comprises a lamp holder; the upper surface of the lamp holder is fixedly connected with a right connecting hole; the connecting hole is fixedly connected with a lamp body; and the surface of the lamp holder is fixedly connected with a lampshade through a connecting rod. The invention also discloses a preparation method of the integral type photo-catalytic lamp for air purification. According to the preparation method disclosed by the invention, a first lampshade panel, a second lampshade panel, a third lampshade panel and the lamp body are arranged; each lampshade panel is manufactured from a material consisting of visible light type photo-catalytic materials, so the photo-catalytic materials can have a oxidation reaction with pollutants without additionally arranging other light source equipment by virtue of a light source emitted by the lamp body, and thus the integral type photo-catalytic lamp can realize a high-efficiency and stable photo-catalytic performance and is excellent in effect of removing formaldehyde, benzene and TVOC; and moreover the integral type photo-catalytic material can be widely applied in an actual process due to a relatively large specific surface area.

Description

technical field [0001] The invention belongs to the field of air purification, and in particular relates to an integral photocatalytic lampshade device for air purification. Background technique [0002] In recent years, the increasingly serious indoor air pollution has stimulated people's demand for environmental purification and clean energy technologies. Under this social situation, photocatalytic technology based on solar energy has attracted people's attention due to its low energy consumption and environmental friendliness. [0003] Photocatalytic materials are a class of materials with photocatalytic functions. Photocatalytic technology is one of the most effective means of air purification. Photocatalytic materials can be excited under light conditions, and the photogenerated electrons and photogenerated holes generated will interact with oxygen in the air. React with water molecules to form superoxide radicals and hydroxyl radicals with strong oxidizing power, and ...
