Photocatalysis air purifier

Abstract

The invention discloses an efficient photochemical catalysis air purifier, which consists of a machine box, a filtering device, a fan and a photochemical reacting room. The photochemical reacting room includes a three-dimensional honey comb ceramic halftone which loads a photocatalyst of nano-composite TiO2 and an ultraviolet radiation light which irradiates towards the honey comb ceramic halftone. The photocatalyst is TiO2 adulterated with little iron, lanthanum or cerium hydronium, and the quantity of the added hydronium is 0. 005 percent to 0.5 percent of the total weight. The three-dimensional honeycomb ceramic net of a photocatalyst carrier is a honeycomb ceramic, which is provided with 100 to 600 holes per square inch. The polluted air follows a wind inlet fan to go through the filtering device which consists of a primary filtering net and an active carbon filtering net, and granular articles are removed and volatile organic matters with peculiar smell are absorbed; the gas after primary purifying goes into the photochemical reacting room which is provided with the ultraviolet radiation light, the photocatalyst of nano-composite TiO2 and the three-dimensional honey comb ceramic net, and under an effect of a strong oxidizer which is produced by the reaction of the ultraviolet radiation and the photocatalyst, various organic pollutants in the air can be effectively decomposed.

Description

technical field [0001] The invention relates to an air purification device, in particular to a high-efficiency photocatalytic air purifier. technical background [0002] With the improvement of living conditions, the problem of indoor air pollution has become increasingly prominent, mainly chemical pollution represented by formaldehyde and benzene series compounds, microbial pollution represented by bacteria, mold, and viruses, and physical pollution represented by dust and suspended particles. pollute. Indoor air pollution can cause many diseases and even cancer, and the control of indoor air pollution has attracted more and more attention. At present, commonly used technologies include: spraying disinfectant to sterilize, but there are chemical residues; activated carbon adsorption, but only effective for removing odor gas; with TiO 2 Photocatalysis represented by photocatalysis has become a research hotspot. [0003] CN2774623 discloses a novel photocatalytic air puri...

AI Technical Summary

Problems solved by technology

[0009] At present, there are still some defects in the use of photocatalytic technology to control air pollution, especially TiO 2 The light quantum efficiency and photocatalytic efficiency of the photocatalyst are relatively low, which affects the decontamination effect

The amount of air processed is relatively not large enough to meet the needs of many occasions
