Description

Technical Field

[0001] This invention relates to the field of pipeline disinfection technology, and in particular to an ozone and ultraviolet combined disinfection device for sewage pipelines. Background Technology

[0002] Ultraviolet (UV) disinfection is a commonly used treatment process in urban wastewater treatment facilities, hospital wastewater treatment facilities, and water supply systems. UV light is a type of light that is invisible to the naked eye. Generally, we refer to light with a wavelength of 200nm or higher as UV light. Based on different wavelengths, it can be further subdivided into UVA (315~400nm), UVB (280~315nm), and UVC (200~280nm). Among these, UVC is most easily absorbed by DNA (ribonucleic acid), and UV disinfection uses UVC. When viral cells are irradiated with ultraviolet light (UVB), the 254nm wavelength UV light is absorbed by the DNA. Adjacent thymine molecules on the DNA strand become entangled, and the resulting dimer hinders the replication of the correct DNA genetic code on the RNA (ribonucleic acid) strand. RNA is the messenger of information, its function being to transmit the DNA code to different parts of the cell. Due to the loss of RNA transmission function, the cell ultimately deteriorates and dies, thus achieving disinfection and sterilization. This disinfection process ensures the biological safety of the water quality, avoids the disinfection byproducts of other chemical disinfection methods, and also avoids the safety impacts and secondary hazards to subsequent water bodies caused by excessive dosage. It is a... Ozone is a truly environmentally friendly disinfection method. While it has extremely high bactericidal efficiency when used for drinking water disinfection, it often requires a large dosage and a long contact time for wastewater disinfection. Ozone acts directly on the cell walls of bacteria, destroying them and causing cell death. Alternatively, ozone releases free radical oxygen when it decomposes in water. Free radical oxygen has strong oxidizing power and can penetrate cell walls to oxidize and decompose glucose oxidase, which is essential for the oxidation of glucose inside bacteria. It can also directly interact with bacteria and viruses, destroying their organelles and ribonucleic acid, and decomposing macromolecular polymers such as DNA, RNA, proteins, lipids, and polysaccharides, thereby disrupting the metabolic and reproductive processes of bacteria.

[0003] Chinese Patent Publication No. CN111533242B discloses an ozone and ultraviolet combined disinfection device suitable for sewage pipelines. The device includes a main unit, a telescopic support arm, roller pressure sensors, a motor, a hydraulic control device, an aeration pipe, a nano-aeration disc, an ultraviolet lamp ring, an infrared CCTV, a sediment detector, an ozone generator, an 0RP probe, and an information collection and control server. The motor drives the rollers on the telescopic arm to move the disinfection device freely within the pipeline. Remote control of the disinfection device allows for precise movement and locking of the aeration pipe, nano-aeration disc, and ultraviolet lamp ring within the pipeline. Utilizing long-distance sewage pipelines as a treatment reaction tank increases disinfection contact time. The combined ozone and ultraviolet disinfection technology efficiently inactivates bacteria and viruses within the pipeline. It can enter pipelines of different diameters by adjusting the length of the telescopic arm and the angle of the support arm, exhibiting strong adaptability and flexible operation. Sewage disinfection is completed through remote control, thus avoiding the risks associated with personnel disinfecting within the sewage pipeline. However, the following drawbacks still exist during implementation: While the aforementioned patent documents are applicable to pipes of different diameters and can be remotely controlled to disinfect wastewater, they suffer from the problem that the device only performs combined disinfection at one point in the pipe using a nano-aeration disc and an ultraviolet lamp ring, resulting in a small disinfection range and poor disinfection effect.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example 1, as Figure 1-3As shown, an ozone and ultraviolet combined disinfection device for sewage pipes includes a sheath 1. Fixed sleeves 2 are fixedly connected to both sides of the inner cavity of the sheath 1. A support mechanism 3 is connected to the inner cavity of the two fixed sleeves 2. A disinfection mechanism 4 is provided in the middle of the support mechanism 3. The outer surface of the support mechanism 3 and the outer surface of the disinfection mechanism 4 are together fitted into the inner cavity of the sheath 1. A threaded groove 6 is opened on the left side of the inner cavity of the sheath 1. A rear cover 5 is engaged with the inner cavity of the threaded groove 6.

[0021] It should be noted that this device is used in conjunction with an external ozone generator, connecting pipe, and external power supply. The ozone discharge pipe of the ozone generator and the connection line of the external power supply are both sleeved in the connecting pipe, and the other end of the connecting pipe is connected to the left end of the disinfection mechanism 4.

[0022] By adding fixing sleeves 2 on both sides of the inner cavity of the protective sleeve 1, the support mechanism 3 and the disinfection mechanism 4 can be locked in the inner cavity of the fixing sleeve 2, so that the support mechanism 3 and the disinfection mechanism 4 will not shake when placed in the protective sleeve 1. The protective sleeve 1 and the back cover 5 work together to protect the support mechanism 3 and the disinfection mechanism 4. When needed, rotate the back cover 5 to disengage it from the inner cavity of the threaded groove 6, and then the support mechanism 3 and the disinfection mechanism 4 can be pulled out from the fixing sleeve 2 for use. The left side of the disinfection mechanism 4 is connected to the connecting pipe, and the support mechanism 3 is pushed to extend and support itself in the sewage pipe with the assistance of the disinfection mechanism 4. This device can only be used in sewage pipes of the same diameter. With the cooperation of the connecting pipe, the support mechanism 3 and the disinfection mechanism 4 are powered by an external power source, and the required ozone is released by an ozone generator.

[0023] To assist the support mechanism 3 in its work and for the disinfection mechanism 4 itself to perform combined ozone and ultraviolet disinfection of the inside of the sewage pipe, such as Figure 4 and Figure 5 As shown, the disinfection mechanism 4 includes two connecting rods 41. Four ventilation columns 44 are fixedly connected in a ring array to the middle of the outer surface of each of the two connecting rods 41. A connecting group 42 is fixedly connected to the left end of the left connecting rod 41. A disinfection group 43 is fixedly connected to the opposite surfaces of the two connecting rods 41.

[0024] First, it should be noted that the inner cavities of the two connecting rods 41 are through-holes, used to house wires and ozone delivery pipes. When the connecting group 42 is connected to the connecting pipe, the ozone generated by the ozone generator can enter the connecting group 42, the first disinfection group 43, and the two connecting rods 41 through the ozone discharge pipe. The ozone is discharged into the sewage pipe and sewage through the connecting group 42 and the first disinfection group 43 for ozone disinfection. An external power supply provides power to the first disinfection group 43, enabling it to generate ultraviolet light for ultraviolet disinfection of the sewage pipe and sewage. In addition, ozone can also enter the support mechanism 3 through the ventilation column 44. By pushing the support mechanism 3, it slides and unfolds on the surface of the connecting group 42 and the first disinfection group 43. Ozone enters the support mechanism 3 through the ventilation column 44 and is discharged from the support mechanism 3 to the surrounding area, increasing the ozone emission area and improving the ozone disinfection efficiency. Ultimately, this achieves the purpose of assisting the support mechanism 3 in its work and the disinfection mechanism 4 itself in performing combined ozone and ultraviolet disinfection of the inside of the sewage pipe.

[0025] To further explain, such as Figure 6 As shown, the connecting assembly 42 includes a connecting column 421. The outer surface of the connecting column 421 has symmetrical limiting holes 426 on both the left and right sides. A nano aeration column 422 is fixedly connected to the right side of the outer surface of the connecting column 421. A threaded sleeve 425 is fixedly connected to the left end of the connecting column 421. A battery 423 is fixedly connected to the upper side of the inner cavity of the connecting column 421. A ventilation soft 424 is fixedly connected to the lower side of the inner cavity of the connecting column 421. The right end of the connecting column 421 is fixedly connected to the connecting rod 41 located on the left side.

[0026] It should be noted that the specific installation method of the storage battery 423, the circuit connection method, and the control method in this invention are all conventional designs and are standard design methods used by designers. The input terminal of the storage battery 423 is electrically connected to the output terminal of the external power supply connection line, and the input terminal of the ventilation hose 424 is connected to the ozone discharge pipe of the ozone generator. The connecting pipe is engaged with the threaded sleeve 425.

[0027] In detail, the nano aeration column 422 is connected to the ventilation hose 424 through the ozone delivery pipe. In addition, the ventilation column 44 is also connected to the ventilation hose 424 through the ozone delivery pipe through the inner cavity of the connecting rod 41. The ozone generated by the ozone generator enters the nano aeration column 422 again through the ozone discharge pipe, the ventilation hose 424 and the ozone delivery pipe, and the ozone is discharged through the nano aeration column 422, achieving the aeration effect in the sewage. The ozone disinfects the inner wall of the sewage pipe and the sewage.

[0028] To further explain, such as Figure 7As shown, the disinfection unit 43 includes a connecting column 431. A nano aeration column 432 is fixedly connected to the right side of the outer surface of the connecting column 431. Four mounting slots 433 in a ring array are opened on the left side of the outer surface of the connecting column 431. A base 435 is provided on the left side of the inner cavity of each of the four mounting slots 433. An ultraviolet lamp tube 434 is provided in the inner cavity of the mounting slot 433 and the base 435 on the same side. The right end of the connecting column 431 is fixedly connected to the connecting rod 41 located on the right side, and the left end of the connecting column 431 is fixedly connected to the connecting rod 41 located on the left side.

[0029] In detail, the connecting rod 41 on the left connects the second connecting column 431 to the first connecting column 421, and their inner cavities are interconnected. The second nano-aeration column 432 is also connected to the ventilation hose 424 via the ozone supply pipe. The four ultraviolet lamps 434 are all electrically connected to the battery 423 via wires. The specific installation method, circuit connection method, and control method of the ultraviolet lamps 434 are all conventional designs, which are standard design practices for designers. The base 435 is fixed to the left side of the inner cavity of the mounting slot 433 with screws, which facilitates the installation of the ultraviolet lamps 434. During operation, ozone enters the nano-aeration column 432 through the ozone gas delivery pipe and is discharged through the nano-aeration column 432, disinfecting the inner wall of the sewage pipe and the sewage with ozone aeration. At the same time, the ultraviolet lamp tube 434 is turned on, generating ultraviolet light to disinfect the inner wall of the sewage pipe and the sewage, achieving the purpose of combined ozone and ultraviolet disinfection. Moreover, there is a certain distance between the nano-aeration column 432 and the nano-aeration column 422, increasing the range of ozone aeration and making its disinfection effect greater than the disinfection effect when the nano-aeration column 432 or the nano-aeration column 422 are used alone.

[0030] Example 2: This example further improves the disinfection efficiency of ozone and ultraviolet combined disinfection based on Example 1, such as... Figure 8 and Figure 9 As shown, the support mechanism 3 includes two sleeve rods 32. The outer surface of each sleeve rod 32 has four rotating grooves 39 arranged in a ring on the right side. The inner cavity of the eight rotating grooves 39 is provided with a support group 33. The opposite surfaces of the two sleeve rods 32 are fixedly connected to four fixing rods 34. The right end of the right sleeve rod 32 is fixedly connected to a top cover 31. The inner cavity of the top cover 31 is fixedly connected to the right side. The left side of the support group 33 is fixedly connected to a sliding sleeve 35. The inner right side of the inner cavity of the sliding sleeve 35 has symmetrically arranged mounting slots 36. The inner cavities of the two mounting slots 36 are fixedly connected to button pins 37. The output ends of the two button pins 37 are slidably connected to the inner cavities of two limiting holes 426 on the same side.

[0031] It should be noted that the button latch 37 in this invention is a conventional design method used by designers. When the button latch 37 is pressed once, the output end of the button latch 37 will be locked in the inner cavity of the limiting hole 426. When pressed again, the output end of the button latch 37 will disengage from the inner cavity of the limiting hole 426 and retract into the inner cavity of the button latch 37.

[0032] First, press the button latch 37 once to disengage the output end of 37 from the inner cavity of the left-side limiting hole 426. This pushes the sliding sleeve 35 to move to the right side of the outer surface of the connecting column 421, simultaneously pushing the support assembly 33. This moves the button latch 37 to the position of the right-side limiting hole 426. Press the button latch 37 again to lock the output end of the button latch 37 into the inner cavity of the limiting hole 426, fixing the sliding sleeve 35. With the cooperation of the rotating groove 39, the support assembly 33 extends. At this time, ozone is emitted through the support assembly 33. Aeration and ultraviolet radiation are generated, which simultaneously disinfects the inner wall of the sewage pipe and the sewage. By extending the support group 33 and fixing rod 34 to extend the distance between the left and right sides of the support group 33, the ozone aeration range is increased and the ozone aeration is more uniform. At the same time, the ultraviolet irradiation range is also increased, which ultimately achieves the purpose of further improving the disinfection efficiency of ozone and ultraviolet combined disinfection. Through the cooperation of sliding sleeve 35, button locking post 37 and limiting hole 426, the extension of the support group 33 is convenient and quick, easy to use and simple to operate.

[0033] To further explain, such as Figure 10 and Figure 11 As shown, the support assembly 33 includes two sliding sleeves 331. Four rotating grooves 339 are arranged in a circular array on the right side of the outer surface of each sliding sleeve 331. An auxiliary rod 333 is rotatably connected to the inner cavity of each of the four rotating grooves 339 on the same side. A support rod 334 is rotatably connected to the outer surface of each of the four auxiliary rods 333 on the same side away from the rotating grooves 339. An installation groove 335 is formed on the outer surface of each of the four support rods 334 on the same side. An ultraviolet lamp 336 is installed inside the inner cavity of each of the four installation grooves 335 on the same side. The four support rods 334 on the same side... Disinfection group 2 338 is fixedly connected to each other on the side that is close to each other. Two fixed rods 2 332 are fixedly connected to the opposite surfaces of the two sliding sleeves 2 331. Rollers 337 are rotatably connected to the side of the four support rods 334 on the same side that are close to the auxiliary rods 333. The side of the four support rods 334 on the same side that is away from the auxiliary rods 333 is rotatably connected to the inner cavity of the four rotating grooves 1 39 respectively. The inner cavity of the right sliding sleeve 2 331 is slidably connected to the outer surface of the connecting column 2 431. The inner cavity of the left sliding sleeve 2 331 is slidably connected to the outer surface of the connecting column 1 421.

[0034] It should be noted that the specific installation method, circuit connection method, and control method of the ultraviolet lamp tube 336 in this invention are all conventional designs and are standard design methods used by designers. Furthermore, the ultraviolet lamp tube 336 is electrically connected to the battery 423 via wires.

[0035] In detail, when the sliding sleeve 35 is pushed, with the cooperation of the fixed rod 332, the two sliding sleeves 331 slide to the right on the outer surfaces of the connecting column 421 and the connecting column 431 respectively. The sliding of the sliding sleeve 331 causes the auxiliary rods 333 on the same side to rotate in the inner cavity of the rotating groove 339 on the same side, and the four support rods 334 on the same side to rotate in the inner cavities of the four rotating grooves 39 on the same side. This causes the four auxiliary rods 333 and the support rods 334 on the same side to rotate closer to each other, and finally causes the four support rods 334 on the left and right sides to extend, so that the four rollers 337 on the left and right sides abut against the inner wall of the sewage pipe for support. At the same time, it drives the disinfection group 338 on the same side to unfold. By turning on and extending the ultraviolet lamp tube 336 in the support rod 334, the ultraviolet irradiation range is larger and the irradiation is more uniform. The unfolded disinfection group 338 also increases the ozone aeration range.

[0036] To further explain, such as Figure 12 and Figure 13 As shown, each of the four disinfection groups 338 on the same side includes a connecting plate 3381. On the right side of the four connecting plates 3381 on the same side, which are close to each other, a ventilation column 3386 is fixedly connected. On the right side of the four connecting plates 3381 on the same side, which are close to each other, a folding rod 3384 is rotatably connected. On the side of the four folding rods 3384 on the same side, which is away from the connecting plate 3381, a connecting plate 3383 is rotatably connected. On the middle of the side of the four connecting plates 3383 on the same side, which are close to each other, a flexible membrane 3382 is fixedly connected. On the side of the four flexible membranes 3382 on the same side, which is away from the connecting plate 3383, the four connecting plates 3381 are respectively connected to... The four ventilation columns 3386 on the same side are fixedly connected on opposite sides, and the ends of the four ventilation columns 3386 on the same side that are far apart from each other all pass through the connecting plate 3381 and are fixedly connected to the four flexible membranes 3382 respectively. The outer surfaces of the four flexible membranes 3382 on the same side are provided with a number of air holes 3387. The ends of the four connecting plates 3383 on the same side that are far apart from the flexible membranes 3382 are fixedly connected to the sides of the four support rods 334 that are close to each other. The ends of the four connecting plates 3381 on the same side that are close to each other are fixedly connected to the outer surface of the connecting rod 41 on the same side. The ends of the four ventilation columns 3386 on the same side that are close to each other are fixedly connected to the four ventilation columns 44 on the same side respectively.

[0037] In detail, the rotation of the support rod 334 causes the connecting plate 3383 to rotate as well. The rotation of the connecting plate 3383 causes the folding rod 3384 to rotate and unfold. At the same time, with the cooperation of the connecting plate 3381, the connecting plate 3383 also causes the flexible membrane 3382 to unfold. At this time, ozone enters the ventilation column 44 through the ozone gas delivery pipe, and then enters the flexible membrane 3382 through the ventilation column 44 and the ventilation column 3386. Finally, it is evenly discharged through several air holes 3387, making the ozone aeration more uniform and increasing the ozone aeration range, thereby improving the ozone disinfection efficiency. That is, the rotation of the support rod 334 not only supports the entire device, but also causes the ultraviolet lamp tube 336 and the flexible membrane 3382 to extend, further increasing the ozone disinfection range and the ultraviolet irradiation range, and improving the disinfection efficiency of ozone and ultraviolet combined disinfection.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
