Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater sterilization and disinfection device using ultraviolet photocatalytic oxidation. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater through physical, chemical, or biological methods to meet discharge or reuse standards. Ultraviolet photocatalytic oxidation for wastewater sterilization and disinfection utilizes the synergistic effect of ultraviolet light and photocatalysts to generate strong oxidizing substances, such as hydroxyl radicals, which destroy the DNA / RNA structure of microorganisms. At the same time, the direct bactericidal effect of ultraviolet light is used to achieve wastewater treatment and disinfection.

[0003] Titanium dioxide generates hydroxyl radicals under ultraviolet light, which can thoroughly kill and decompose harmful substances such as bacteria, viruses, and bacterial spores in water. However, during long-term use of the sterilization and disinfection device, some calcium ions will be adsorbed on the quartz tube and the titanium dioxide catalytic coating, forming scale. This weakens the intensity of ultraviolet light emitted from the quartz tube and affects the effective catalytic area of ​​titanium dioxide, ultimately affecting the sterilization and disinfection effect of the photocatalytic sterilization and disinfection device.

[0004] To address the aforementioned technical issues, CN207276254U discloses a photocatalytic sterilization and disinfection device. By setting a cleaning component inside the tube, the cleaning component slides along the quartz tube under the drive of the driving component. The flexible cleaning block on the cleaning component cleans the scale on the outer wall of the quartz tube and the titanium dioxide catalytic coating, thereby increasing the intensity of ultraviolet light transmitted through the quartz tube and increasing the effective catalytic area of ​​the titanium dioxide catalytic coating, ultimately improving the sterilization and disinfection effect of the photocatalytic sterilization and disinfection device.

[0005] The existing technology has the following shortcomings: in actual use, since the catalyst coating is always in a fixed position, it can only carry out catalytic oxidation reaction on wastewater near the fixed position, which reduces the effect of catalytic reaction on wastewater. Utility Model Content

[0006] The purpose of this invention is to provide an ultraviolet photocatalytic oxidation wastewater sterilization and disinfection device, which has the advantage of adjustable catalyst position. By changing the required position during oxidation catalysis according to the uniform rotation method, the effect of wastewater treatment is improved, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an ultraviolet photocatalytic oxidation wastewater sterilization and disinfection device, comprising a tank;

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This invention effectively improves the sterilization and disinfection effect of wastewater through the coordinated arrangement of an ultraviolet irradiation mechanism and a catalytic mechanism. It adopts an adjustable catalyst coating position to uniformly oxidize the wastewater.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides an ultraviolet photocatalytic oxidation wastewater sterilization and disinfection device, including a tank body 1;

[0035] The top of the tank 1 is equipped with an ultraviolet irradiation mechanism 2 for ultraviolet photocatalysis, and the inside of the tank 1 is equipped with a catalytic mechanism 3 for wastewater catalytic oxidation.

[0036] The ultraviolet irradiation mechanism 2 includes:

[0037] A connecting component is located at the top of the barrel 1, and an ultraviolet light irradiation component is installed inside the connecting component.

[0038] Catalytic mechanism 3 includes;

[0039] A drive component is located at the top of the connecting component. A transmission component and a support component connected to the transmission component are located at the bottom of the drive component. A reaction component is located at the bottom of the support component.

[0040] Preferred;

[0041] like Figure 3 As shown, the connecting components include;

[0042] The top cover 21 is installed on the top of the barrel 1. A quartz tube 22 is placed through the top of the top cover 21. The top cover 21 can seal the top of the barrel 1 and support the structure installed on the top cover 21. The quartz tube 22 can cover and protect the ultraviolet lamp group 24.

[0043] further;

[0044] like Figure 3 As shown, the ultraviolet component includes;

[0045] The connecting cover 23 is threaded to the outside of the quartz tube 22. The inner cavity of the quartz tube 22 is bolted with an ultraviolet lamp assembly 24. The connecting cover 23 facilitates the connection with the quartz tube 22 to fix the ultraviolet lamp assembly 24. When the ultraviolet lamp assembly 24 is working, it generates ultraviolet light to treat the surrounding sewage.

[0046] During installation, the quartz tube 22 is removed directly. At this time, the ultraviolet lamp assembly 24 is assembled with the quartz tube 22. The ultraviolet lamp assembly 24 is located inside the quartz tube 22. Then, it passes through the top cover 21 from top to bottom into the inside of the barrel 1, and then continues to move downward until it is blocked by the connecting cover 23. Then, the quartz tube 22 is rotated to make it threadedly connected with the connecting cover 23 to form a fixed connection. Then, the ultraviolet lamp assembly 24 is started to perform ultraviolet irradiation.

[0047] It is worth explaining;

[0048] like Figure 4 As shown, the driving component includes;

[0049] The motor 31 is bolted to the top of the top cover 21. The output shaft of the motor 31 is keyed to the shaft 32. The motor 31 performs the power output operation, while the shaft 32 realizes the transmission of rotational force.

[0050] in;

[0051] like Figure 4 As shown, the transmission assembly includes;

[0052] Gear 33 is fixedly installed at the bottom end of shaft 32. Gear ring 34 meshes with the outer side of gear 33. When the gear is driven to rotate, it causes gear 33 to rotate and mesh, which in turn drives gear ring 34 to rotate, thereby completing the transmission of rotational force.

[0053] Going a step further;

[0054] like Figure 4 As shown, the supporting components include;

[0055] The outer ring 35 is fixedly installed on the inner wall of the barrel 1. The inner wall of the outer ring 35 is rotatably connected to the inner plate 36, so that the outer ring 35 can rotate and support the inner plate 36, and the inner plate 36 supports the components connected to it.

[0056] at last;

[0057] like Figure 4 As shown, the reaction components include;

[0058] The connecting block 37 is threaded through the top of the inner plate 36. The catalyst coating tube 38 is fixedly installed at the bottom of the connecting block 37 to facilitate its disassembly and assembly. It is also used to cooperate with ultraviolet light for catalytic oxidation to achieve sterilization and disinfection of wastewater.

[0059] When working, the catalyst coating tube 38 needs to be pre-installed, and the surface of the tube is coated with a catalyst, which can be titanium dioxide. Then, the catalyst coating tube 38 is taken out and passed through the inner plate 36 in sequence. When it cannot be passed through directly, the catalyst coating tube 38 needs to be rotated to connect with it by thread, so as to make a fine adjustment downward again and form an installation and fixing operation.

[0060] Then, the top cover 21 can be installed as described above. When the top cover 21 is installed, the gear 33 and the gear ring 34 mesh. At this time, the position does not need to be changed. The ultraviolet light generated by the ultraviolet lamp group 24 directly irradiates the catalyst coating tube 38 to form a photocatalytic reaction. When the ultraviolet light irradiates the photocatalyst such as titanium dioxide, it will excite the catalyst surface to generate electrons and holes. These active particles react with water molecules and oxygen to generate strong oxidizing substances such as hydroxyl radicals and superoxide radicals. These free radicals can decompose the DNA / RNA structure of bacteria and viruses non-selectively, block the replication of genetic material, and ultimately inactivate them.

[0061] Then, to improve the uniformity of wastewater sterilization and disinfection, the motor 31 is started and drives the gear 33 to rotate slowly and uniformly through the shaft 32. According to the meshing principle, the gear 33 will drive the gear ring 34 and the inner plate 36 connected to it to rotate. When the inner plate 36 rotates, it will drive the catalyst coating tube 38 installed with it to rotate together until it reaches the preset position and then stop rotating. Then, the photocatalytic reaction will be carried out again to improve the sterilization and disinfection effect during wastewater treatment. At the same time, the catalyst coating tube 38 can be adjusted to perform photocatalytic reaction operations at different positions as needed.

[0062] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
