Problems solved by technology

[0005] 1. The above-mentioned patent needs to install an ultraviolet lamp inside the device, which cannot use sunlight to directly react with the titanium dioxide photocatalytic coating, and the cost is high. At the same time, it is necessary to control the ultraviolet lamp in real time during use, which is troublesome;
[0006] 2. The purification effect of the above patents is poor, and the hydroxyl radicals produced by the reaction between the ultraviolet lamp and the titanium dioxide photocatalytic coating cannot fully react with the water body;
[0007] 3. The purification function of the above-mentioned patents is relatively simple, and the water body can only be purified by the reaction of the ultraviolet lamp and the titanium dioxide photocatalytic coating, and it is impossible to make the silica powder and the water body form a suspension system at the same time;

Abstract

The invention relates to the technical field of sterilization and disinfection devices, and discloses a photocatalytic sterilization and disinfection device. The device comprises a bottom cylinder, and a plurality of top cylinders are uniformly and fixedly mounted at the edge of the top of the bottom cylinder. Bearings are fixedly mounted at the tops of the inner walls of the top cylinders, and quartz sleeves are fixedly mounted on the inner walls of the bearings. Water outlet pipes are fixedly installed on the outer walls of the top cylinders, and the inner walls of the top cylinders are each coated with a titanium dioxide photocatalytic coating. Light filtering assemblies used for filtering ultraviolet rays in sunlight and diffusing the ultraviolet rays are arranged in the quartz sleeves. Sunlight is gathered and irradiated to ultraviolet light filters under the action of collecting lenses. On one hand, the ultraviolet light filters can filter out other stray light and only keeps ultraviolet light. On the other hand, the ultraviolet light can be vertically and downwards emitted to concave lenses by utilizing inner concave cambered surfaces, and the ultraviolet light is diffused all around under the action of the concave lenses, penetrates through the quartz sleeves and is irradiated to the titanium dioxide photocatalytic coatings on the inner walls of the top cylinders to generate hydroxyl radicals, so that the water in the top cylinders can be purified.

Description

technical field [0001] The invention relates to the technical field of sterilization and disinfection devices, in particular to a photocatalytic sterilization and disinfection device. Background technique [0002] Photocatalytic water purification technology mainly uses hydroxyl radicals to completely kill and decompose harmful substances such as bacteria, viruses, and bacterial spores in water. It has the advantages of high efficiency, energy saving, cleanness and non-toxicity, and is a water treatment technology with great development prospects. At present, the use of silica photocatalytic technology to treat water pollution generally adopts the following two methods: one is to form a suspension system with silica powder and water to be treated, and the suspension state has high purification efficiency; the other is to use silica to coat The form of the layer is fixed on the carrier, which has a longer service life. [0003] The Chinese patent announcement number is: the ...
