Abstract

The invention belongs to the technical field of environmental protection, and relates to an air purification device and an air purification system. The air purification device comprises a reactor, a transparent photocatalytic substrate group, a light source and a reflection unit, wherein the transparent photocatalytic substrate group, the light source and the reflection unit are arranged inside the reactor, the transparent photocatalytic substrate group is composed of a plurality of transparent photocatalytic substrates arranged at intervals, the plurality of transparent photocatalytic substrates are arranged in a staggered mode to form a curved airflow channel allowing air to circulate, each transparent photocatalytic substrate is loaded with a photocatalyst material, the reflection unitis arranged in the light lay emission direction of the light source, and the reflection unit can reflect light rays emitted by the light source onto the transparent photocatalytic substrates. The photocatalytic air purification device is provided with tempered photocatalytic glass and a reflective mirror so that the light energy can be utilized to the maximum extent; the S-shaped gas channel is arranged so that the photocatalytic reaction time can be effectively prolonged, and the air purification can be more thorough; the photocatalytic efficiency is high; and compared with a traditional technology, the air purification device and the air purification system have the advantages that the design is scientific and reasonable, the air purification effect is obvious.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to gas purification equipment, in particular to an air purification device and an air purification system. Background technique [0002] There are more than 500 kinds of volatile organic compounds in the indoor air, including more than 20 kinds of carcinogens and more than 200 kinds of pathogenic viruses. Among them, the most harmful pollutants are: ammonia, formaldehyde, benzene, radon, esters, and trichlorethylene Wait. Indoor air pollution is 2 to 5 times more serious than outdoors, and the harmful substances in the air in the car are 5 to 10 times higher than those in homes and offices. According to the survey, 68% of diseases are caused by indoor pollution, and indoor air pollution has become one of the five major environmental factors that endanger human health. [0003] In the prior art, technologies commonly used in air purifiers include adsorption technology...
