A folded plate type filter screen photocatalytic reactor is disclosed. The photocatalytic reactor includes a shell. The left and right ends of the shell are a gas feeding end and a gas discharging endrespectively. The inside of the shell is a gas flow passage. An air purification unit having a shape of a Chinese character 'Gong' is disposed in the shell, and includes a plurality of horizontally disposed filter screens. Heads and tail ends of the adjacent filter screens form a structure having a shape of a Chinese character 'Gong' through staggered solid plates. The shell between each two adjacent filter screens is provided with an ultraviolet lamp group. The filter screens are covered with catalytic layer film. The gas passage having a shape of a Chinese character 'Gong' and formed by thefoam nickel filter screens is utilized to increase the effective area of a photocatalytic reaction. Through increasing the total face area, the air velocity when gas passes through the filter screensis reduced, the residence time of the gas in the reactor is increased, and the utilization rate of ultraviolet sources is increased. Because of blocking functions of the solid plates, gas disturbanceeffects are enhanced, and convective mass transfer effects are enhanced.
Description
technical field [0001] The invention relates to a photocatalytic reactor, in particular to a folded plate type filter screen photocatalytic reactor. Background technique [0002] With the progress of society and the improvement of quality of life, people have higher and higher requirements for air quality. In recent years, due to the extensive use of architectural coatings and decorative materials, the indoor air pollution has become increasingly serious, and the concentration of volatile organic compounds (VOCs) such as formaldehyde, toluene, and benzene is too high. Excessive concentration of pollutants is one of the important factors leading to the decline of indoor air quality (IAQ), which will have a serious impact on human health and work efficiency. Photocatalytic oxidation technology can effectively remove VOCs in indoor air, and has a good bactericidal effect and the ability to inhibit virus activity. attention. [0003] Photocatalytic reactor is an important dev...
