Abstract
Description
Technical Field
[0001] This invention relates to the field of ultraviolet sterilization technology, specifically to an ultraviolet sterilization and purification device. Background Technology
[0002] Ultraviolet (UV) sterilization works by using ultraviolet light to damage the DNA and RNA of organisms, preventing their replication and growth, thus achieving highly efficient sterilization. Furthermore, UV sterilization does not require chemical agents, therefore it does not produce chemical residues or harmful gases, reducing potential risks to the environment and health. It also does not produce odors and is relatively safe, as it does not release UV radiation into the surrounding environment. In contrast, reverse osmosis membranes filter bacteria from the raw water. These bacteria are blocked by the reverse osmosis membrane as they pass through, accumulating on its surface. Simultaneously, the accumulated bacteria and microorganisms on the reverse osmosis membrane multiply and metabolize, producing large amounts of colloidal substances, which can clog the membrane and cause a sharp drop in membrane flux. Therefore, sterilization treatment is often performed on the raw water during transportation. In existing technologies, the disinfection of fluids transported within pipelines often involves embedding ultraviolet (UV) lamps inside the pipes. However, the fluid flow rate within the pipes is relatively fast. To ensure sufficient sterilization by the UV lamps, the flow time within the device is typically increased by reversing the flow path or obstructing the flow. This method requires the water flow to bend and change direction, resulting in significant resistance and a long path, which can easily lead to poor flow and hinder stable water circulation. Furthermore, changing the pipe diameter generally requires fewer pipes, and each pipe needs its own UV lamp for stable irradiation, leading to low efficiency. Increasing the number of UV lamps also requires more energy, resulting in overall waste, low sterilization efficiency, and a long overall disinfection time. Summary of the Invention

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] Combined with appendix Figures 1-5 The ultraviolet sterilization and purification device includes a spray mechanism 61 installed in the sterilization chamber 14.
[0018] The spraying mechanism 61 includes a collection block 21 fixedly disposed inside the sterilization chamber 14. The collection block 21 is provided with a collection trough 23 for collecting the fluid that has undergone sterilization once. A water pump 25 is fixedly disposed inside the collection block 21. An inlet 24 is fixedly disposed on the water pump 25 and is fixedly connected to the collection trough 23. The outlet of the water pump 25 is fixedly connected to a drain hose 27. Drain interfaces 26 are fixedly arranged at equal intervals on the drain hose 27. The other end of the drain interface 26 is fixedly connected to a corresponding spray chamber 22. The spray chambers 22 are arranged at equal intervals inside the collection block 21. The fluid can be sprayed onto the inner wall of the sterilization chamber 14 through the spray chambers 22.
[0019] Advantageously, a diversion pipe 13 is fixedly provided above the sterilization chamber 14. The diversion pipe 13 is connected to the sterilization chamber 14 via a flange. A diversion plate 16 is fixedly provided at one end of the diversion pipe 13 near the sterilization chamber 14. Water column outlet holes 17 are fixedly arranged at equal intervals on the diversion plate 16. A connecting plate 20 is fixedly arranged at equal intervals below the diversion plate 16. A corresponding ultraviolet lamp fixing plate 18 is fixedly provided below the connecting plate 20. A corresponding annular ultraviolet lamp 19 is fixedly provided below each ultraviolet lamp fixing plate 18. The connecting plate 20, the ultraviolet lamp fixing plate 18, and the annular ultraviolet lamp 19 do not obstruct the water column outlet holes 17 and do not affect the flow of fluid from the water column outlet holes 17.
[0020] Advantageously, the other end of the diversion pipe 13 is fixedly provided with an inlet connection pipe 11, the diversion pipe 13 is flange-connected to the inlet connection pipe 11, and the end of the sterilization chamber 14 away from the diversion pipe 13 is fixedly provided with a drain connection pipe 12, the sterilization chamber 14 is flange-connected to the drain connection pipe 12.
[0021] Advantageously, a control terminal 15 is fixedly provided on the sterilization chamber 14. The control terminal 15 is used to control the driving of the ultraviolet lamp fixing plate 18 and the water pump 25. The water pump 25 sprays the fluid in the collection tank 23 onto the inner wall of the sterilization chamber 14 with such force that it does not cause strong splashing of the fluid.
[0022] How to use this invention:
[0023] In the initial state: the surface of the annular ultraviolet lamp 19 is unobstructed, and the water inlet 24 and the spray chamber 22 are not blocked.
[0024] When using this invention, the user needs to install the end of the diversion pipe 13 away from the sterilization chamber 14 onto the inlet connection pipe 11, and the end of the sterilization chamber 14 away from the diversion pipe 13 onto the drain connection pipe 12. The inlet connection pipe 11 and the drain connection pipe 12 are then installed on their respective pipes. The sterilization chamber 14 is perpendicular to the horizontal plane. The user then drives the annular ultraviolet lamp 19 to start via the control terminal 15. After the annular ultraviolet lamp 19 is started, it needs to irradiate for a period of time to fully sterilize and disinfect the inner wall of the sterilization chamber 14 and the surface of the collection block 21. After the ultraviolet lamp 19 has been working for a period of time, the user can start the transport of fluid through the connected pipe. Once the connected pipe starts transporting fluid, the unsterilized fluid will enter the diversion pipe 13 through the inlet connection pipe 11. The unsterilized fluid entering the diversion pipe 13 will be restricted by the water column outlet 17 and flow out from the water column outlet 17, thereby entering the sterilization chamber 14. The water column flowing out from the water column outlet 17 will flow out from the gap between the ultraviolet lamp fixing plate 18 without contacting the connecting plate 20, the ultraviolet lamp fixing plate 18, and the annular ultraviolet lamp 19. At this time, the liquid flowing out from the water column outlet 17 will be affected by gravity. The liquid flowing through the water column outlet 17 forms a water column. This column passes between the annular ultraviolet lamps 19 and is fully irradiated by the light from the lamps. Without obstruction from glass or other glass, the water column formed through the outlet 17 is thoroughly sterilized. After this initial sterilization, the water column falls into the collection tank 23. The user needs to activate the water pump 25 via the control terminal 15 beforehand. Once activated, the water pump 25 collects the sterilized fluid from the collection tank 23, pumps it into the pump through the inlet 24, and discharges it into the spray chamber 22 through the drain port 26. Under the action of the water pump 25, the fluid that has undergone one sterilization is sprayed out along the path of the spray chamber 22 and finally sprayed onto the inner wall of the sterilization chamber 14. At this time, the fluid that has undergone one sterilization will slowly flow down the sterilization chamber 14. At this time, its area is large and its overall thickness is thin. During its flow down the sterilization chamber 14, it will be fully irradiated by the annular ultraviolet lamp 19, which greatly extends the overall irradiation time. After the fluid has been fully irradiated twice, it has also completed sterilization. The water column formed by the fluid under the action of gravity will not greatly reduce the overall flow rate and efficiency due to diversion. Finally, the sterilized fluid will fall into the drain connection pipe 12 along the sterilization chamber 14 to wait for subsequent use.
