Photocatalyst sterilizer and sterilization method thereof

Abstract

The invention discloses a photocatalyst sterilizer and a sterilization method thereof. The photocatalyst sterilizer comprises a mounting base, fixed tables are arranged at the bottoms of the two sidesof the mounting base, a control table is arranged at the top of one set of fixed tables, a servo motor is arranged at the top of the other set of fixed tables, and a gear is arranged at the output end of the servo motor; and a flow inlet is formed in the middle of the top of the mounting base, an ultraviolet sterilization lamp is arranged in the middle of the bottom of the mounting base, and a photocatalyst carrier B matched with the ultraviolet sterilization lamp is arranged on the outer side, close to the ultraviolet sterilization lamp, of the bottom of the mounting base. Through mutual cooperation of flow dividing and liquid guiding assemblies, secondary filtering can be conducted before photocatalyst sterilization work is used, water liquid is annularly dispersed and guided between asterilization system, in this way, the contact efficiency of a subsequent photocatalyst catalytic reaction is improved, meanwhile, sterilization light is prevented from being covered with excessive water liquid, and the affinity of water liquid and the sterilization system is improved.

Description

technical field [0001] The invention relates to the technical field of photocatalyst sterilizers, in particular to a photocatalyst sterilizer and a sterilization method thereof. Background technique [0002] Photocatalyst is a general term for a photo-semiconductor material with photocatalytic function represented by nano-scale titanium dioxide. It is coated on the surface of the substrate, and under the action of ultraviolet light and visible light, it produces a strong catalytic degradation function and can effectively degrade the air. Toxic and harmful gases, can effectively kill a variety of bacteria, and can decompose and harmless the toxins released by bacteria or fungi, and also have the functions of removing formaldehyde, deodorizing, anti-pollution, and purifying air; [0003] When the photocatalyst sterilizer sterilizes sewage, because of the large density and liquid volume of sewage, the water liquid cannot be well dispersed, so that the contact surface between th...

Problems solved by technology

[0003] When the photocatalyst sterilizer sterilizes sewage, because of the large density and liquid volume of sewage, the water liquid cannot be well dispersed, so that the contact surface between the subsequent photocatalyst and ultraviolet rays is small, and the efficiency of the catalytic reaction is limited. reduced, thereby reducing the original sterilization treatment effect of the photocatalyst sterilizer; when the photocatalytic carrier contacts the water that needs to be filtered, it will carry out hydrophilicity and decomposition of the water, but with the increase of the water, The diffusion effect of the light effect will also be covered, so that the water cannot trigger the oxidation and catalytic function well, which increases the difficulty of sterilization work, and the foul smell of sewage is difficult to purify, reducing the practicability of photocatalyst sterilization treatment; When encountering difficult-to-treat sewage, the photocatalyst sterilization work may require secondary treatment. However, during the secondary treatment, the operator often needs to repeatedly pick up and overturn the water, which is extremely inconvenient and reduces the convenience of the secondary treatment work of the device. sex
