Ultraviolet LED based photocatalyst air purification system

Abstract

The invention discloses an ultraviolet LED based photocatalyst air purification system. The system comprises a purification part and a purification detection part. The purification part comprises a base, a light source, a photosensitive layer, a photocatalysis net and a transparent shell. The light source is installed on the base, the photosensitive layer is arranged below the light source, the photocatalysis net is located above the light source, and the transparent shell covers the upper portion of the photocatalysis net. The photosensitive layer is a ZrO2 coating. Manufacturing of the photocatalysis net comprises the following steps that (1) nano TiO2 white powder is taken to prepare a 5% TiO2 suspension solution; and (2) a net-shaped cover is coated with the solution, and air-drying iscarried out. The detection part is used for detecting the purification degree in the transparent shell. The detection part comprises a sensor, an amplifier, a digital multimeter and a direct-currentpower supply, the sensor is located in the shell, and the amplifier and the digital multimeter are located outside the shell. The sensor is electrically connected with the amplifier, the amplifier iselectrically connected with the digital multimeter, and the amplifier and the digital multimeter are respectively connected with the direct-current power supply. The UV-LED lamp based photocatalyst air purification device has a good air purification effect.

Description

technical field [0001] The invention relates to the field of air purification devices, in particular to a photocatalyst air purification system based on ultraviolet LEDs. Background technique [0002] Nowadays, air pollution poses a non-negligible harm to human health, and the air pollution caused by chemical plants affects people's living environment even more. There are mainly formaldehyde, hydrogen sulfide, benzene, toluene, xylene, ammonia, TVOC and other pollutants in the air. With the continuous progress of society and the improvement of people's material and cultural living standards, people's requirements for their own living environment are also getting higher and higher. Purify. At present, most of the indoor air purifiers on the market use ozone generators. With the emergence of photocatalyst coatings, there is an indoor air purifier using photocatalysts. The nano-photocatalytic net can purify the air, but the general daylight and bulb-colored fluorescent tubes ...

Problems solved by technology

At present, most of the indoor air purifiers on the market use ozone generators. With the emergence of photocatalyst coatings, there is an indoor air purifier using photocatalysts. On the nanometer photocatalytic network, the air is purified, but the general daylight and bulb-colored fluorescent tubes or energy-saving lamps only have a small amount of ultraviolet light, the effectiveness of the photocatalyst will be greatly reduced, and its photocatalyst purification effect cannot be fully exerted
