Problems solved by technology

[0002] At present, the environmental pollution is serious, water pollution and air pollution have become common problems faced by all mankind, and the disinfection and sterilization technologies required in various fields are insufficient, including the disinfection and sterilization technologies used in the control of water pollution and air pollution. Secondary pollution, high cost, incompleteness
As an efficient and safe purification technology, photocatalytic technology also has certain limitations. Photocatalysts have no selectivity in decomposing organic matter. Therefore, the material supporting the catalyst itself will also be decomposed. Once the catalytic particles fall off, the material will become invalid; Second, the agglomeration of catalyst particles is relatively serious, resulting in too small specific surface area and weak catalytic effect, which in turn leads to incomplete oxidation reaction, which easily produces other harmful substances
Third, the photocatalytic reaction is highly selective to the light source and can only react under the action of ultraviolet light, which also limits the catalytic efficiency to a certain extent.

Embodiment 1

[0021] Such as figure 1 As shown, the first embodiment of a high-efficiency photocatalytic disinfection and sterilization device designed by the present invention, the main body of the device is arranged in the tube body 3, and the two ends of the tube body 3 are welded with an inlet pipe 9 and an outlet pipe 2 for The material to be processed enters and exits the tube body. The middle area of ​​the tube body 3 is a processing section, and a casing 5 of transparent material is arranged in the middle of the processing section, and both ends of the casing 5 are sealed, and an ultraviolet lamp 4 is arranged therein. The processing section is filled with spherical high-efficiency reflection units 6 with different diameters on the outside of the casing 5, and is sealed by mesh baffles 32 at both ends of the processing section. The inner wall of the tube body 3 of the treatment section is coated with a composite photocatalytic coating of graphene oxide and titanium dioxide.
