Photocatalysis air purifying device

Abstract

The invention relates to a photocatalysis air purifying device. The device comprises a frame (1) and an ultraviolet lamp tube (2) installed in the frame (1), wherein the frame (1) is provided with an airflow passageway with a cross-ventilation function. The device is characterized in that the frame (1) is internally provided with a titanium-nickel compounded photocatalysis net (3); the titanium-nickel compounded photocatalysis net (3) comprises a photocatalysis titanium net (30) and a photocatalysis nickel net (31); the titanium-nickel compounded photocatalysis net (3) is a compounded photocatalysis antibiosis foam metal net of a three-dimensional space structure and comprises a foam nickel substrate and TiO2 loaded on the surface of the foam nickel substrate; the air inlet of the airflow passageway of the frame (1) is provided with a dust filtering net (4); the outlet of the airflow passageway of the frame (1) is provided with strip bars (7) or a porous baffle; and a fan (6) is arranged in the frame (1) or at the rear part of the frame (1). By using the photocatalysis air purifying device of such structure, the effects of volatile organic compound (VOC) degradation, disinfection and sterilization are obvious.

Description

Technical field [0001] The invention belongs to the technical field of air purification equipment manufacturing, and specifically relates to a photocatalytic air purification device. Background technique [0002] With the rapid economic development, various environmental pollutions, especially indoor air pollution caused by indoor decoration, have attracted widespread attention. Indoor environmental pollution caused by construction, decoration, and furniture has become a major killer that affects people's health. Especially with the popularization of air-conditioning, the indoor space is closed, indoor and outdoor air is not exchanged, so that indoor pollutants cannot be discharged. The comfortable conditions of constant temperature and humidity provide objective conditions for the proliferation of bacteria, which further deteriorates the indoor air condition. . Modern people, especially urban people, spend 90% of their time indoors in a day. Therefore, the impact of indoor air ...

AI Technical Summary

Problems solved by technology

Chemical and physical adsorption and electrostatic dust removal are mainly used to remove suspended particles in the air, and have limited removal effects on organic pollutants and bacteria

Although negative ions can decompose organic matter to a certain extent, they are prone to the problem of incomplete decomposition and harmful by-products, and they do not have the function of sterilization, so the effect on air purification is limited

Photocatalysis has a good effect in sterilization and degradation of VOC (VOC: volatile organic compounds, organic compounds with a boiling point between 50 and 260 degrees, such as toluene, benzene, ethyl acetate and other solvents), without secondary pollution , has the characteristics of environmental protection, economy, and high stability, and is widely used, but the current photocatalytic material is single, and it needs to be further improved in the degradation of organic matter and disinfection and sterilization.
