Abstract

The invention provides an air purification device based on photocatalysis. The air purification device comprises a box body, an air inlet is formed in one end of the box body, an air outlet is formed in the other end of the box body, a photocatalyst generation mechanism is arranged on the inner side of the box body, at least one fan blade and at least two ultraviolet lamps are arranged inside the box body, at least one surfaces of the fan blades are coated with photocatalytic reaction catalysts, the fan blades are installed through a fan blade bracket, the fan blades can be divided into at least two fan-shaped structures, the fan blades are rotatably installed on an adjusting shaft, and the installing mode of the fan blades on the adjusting shaft involves fixed installing or movable installing. According to the air purification device, air which does not pass through the inner wall of the box body is made up, the internal fan blades can quickly respond according to airflow driven by a ventilation fan, corresponding adjustment is completed, the air purification device better adapts to the filtering efficiency, air purification can be more complete, and the purification efficiency is further effectively improved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purification device based on photocatalysis. Background technique [0002] With the progress of society, environmental pollution has gradually attracted more attention from the society, and the air purification technology based on photocatalyst is widely used in environmental water pollution treatment, indoor Air pollution control and industrial waste gas treatment and other fields. [0003] The current photocatalytic air purification device coats the catalyst TiO2 on the filter screen or the inner wall of the ventilation pipe inside the container. When qualified ultraviolet light is irradiated on the surface of the catalyst and a photocatalytic oxidation reaction occurs, hydroxyl groups will be produced to purify formaldehyde in the air. Substances such as polluting gases. The photocatalytic oxidation reaction occurs on the surface of the TiO2 coating, so only ...
