Abstract

The invention discloses a photocatalytic air purifier, which comprises a power, an external shell, a filter layer, a draught flow equipment and a carbonization product carrier supported regular photocatalyst and a photocatalysis air purification component composed of an UV lamp uniformly provided along the axis inside the photocatalyst. The photocatalysis air purification componentis connected tightly with the shells around. The upper part and the lower part around the shells are provided with an air inlet and an air outlet. The filter layer is arranged at the inlet end of the photocatalysis air purification component while the draught flow equipment is at the outlet end. The invention has the advantages of obvious purification effect to the low concentration volatile organic pollutant bytaking the carbonization product carrier supported regular photocatalyst as the core component and the absorption and photocatalytic degradation as the main work pattern; the invention has perfect use effect. The pollutant can be better degrade even if the concentration is low, and secondary pollution can be avoided with excellent treatment effect and easy operation.

Description

Technical field: [0001] The invention relates to a photocatalytic air purifier, in particular to a photocatalytic air purifier manufactured based on a carbon carrier-loaded structured photocatalyst as a core component. Background technique: [0002] At present, for existing air purification devices, the air purification process is basically carried out in two ways: filtration and adsorption. For the filtration and purification method, only the suspended particles in the air are removed, and there is no obvious purification effect on volatile organic pollutants and bacteria; while the adsorption and purification method based on adsorbent materials such as activated carbon involves the adsorption of adsorbent materials. Activation treatment after saturation and easy to cause secondary pollution and other problems, so the actual application effect is not ideal. Recently, several photocatalytic air purifiers have appeared on the market, but in fact, "photocatalysis" has not pla...
