Abstract
Description
Technical Field
[0001] This invention belongs to the field of wastewater treatment technology, specifically relating to a reactor that couples micro-nano bubbles and a photocatalytic device. Background Technology
[0002] Coupling micro- and nano-bubbles with photocatalysis to treat wastewater is an advanced oxidation technology that synergistically enhances physical (micro- and nano-bubbles) and chemical (photocatalysis) effects, significantly improving wastewater treatment efficiency, reducing energy consumption, and achieving deep purification.
[0003] Patent CN216946311U discloses a photocatalytic coupling nanobubble reaction device, comprising: a reaction device filled with photocatalytic material, and the reaction device having an inlet and an outlet. In this photocatalytic coupling nanobubble reaction device, by contacting wastewater containing nanobubbles, the nanobubbles can provide a large amount of dissolved oxygen, promoting the generation of active free radicals during the photocatalytic process. Simultaneously, the nanobubbles can remove pollutants in the wastewater that are difficult to adsorb onto the catalyst surface or that are difficult for the photocatalytic material to treat, thus preparing the photocatalytic material for better performance.
[0004] Although the existing technology can purify wastewater, after prolonged use, pollutants and other impurities in the wastewater tend to adhere to the outer surface of the quartz tube, thus covering a large area of the quartz tube and reducing its light transmission. Therefore, the equipment needs to be shut down by the staff, and the quartz tube needs to be removed from the equipment for cleaning. After cleaning, the quartz tube needs to be reinstalled in its original position, making the overall cleaning process of the quartz tube time-consuming and inconvenient, and thus needs to be improved. Utility Model Content
[0005] The purpose of this invention is to provide a reactor that couples micro / nano bubbles and a photocatalytic device in order to solve the above-mentioned problems.
[0006] This utility model achieves the above objectives through the following technical solutions:
[0007] A reactor coupling micro / nano bubbles and a photocatalytic device includes a reactor body, a dissolved gas pump installed on the outside of the reactor body, and a photocatalytic material disposed within the reactor body. Several staggered quartz tubes are installed within the reactor body, and ultraviolet lamps are fixedly installed inside the quartz tubes. A cleaning mechanism is provided within the reactor body, and a partition is fixedly installed within the reactor body. A reflector is fixedly installed on the top of the partition, and several through holes are opened inside the reflector.
[0008] The cleaning mechanism includes a convex plate slidably disposed in the reactor body, several annular cleaning components fixedly disposed in a circular hole opened in the convex plate, a strip-shaped cleaning component fixedly disposed at the bottom of the convex plate and in cooperation with the top of the reflector, and a driving mechanism installed in the reactor body for driving the convex plate to move, wherein the annular cleaning components are in cooperation with the outer wall of the quartz tube.
[0009] As a further optimization of this utility model, the dissolved air pump is fixedly connected to several water distributors via water pipes, and the water distributors are fixedly installed at the bottom inner side of the reactor body.
[0010] As a further optimization of this utility model, the partition net is located above the water distributor, the photocatalytic material is located on top of the reflector, and the quartz tube is located inside the photocatalytic material.
[0011] As a further optimization of this utility model, the driving mechanism includes a motor fixedly mounted on the outer wall of the reactor body and a threaded rod fixedly mounted on the output end of the motor. The threaded rod is rotatably mounted inside the reactor body, and the convex plate is threaded onto the outer wall of the threaded rod. The two sides of the convex plate abut against the inner wall of the reactor body.
[0012] As a further optimization of this utility model, the convex plate is fixedly provided with fixing rings on both sides, and the fixing rings are fixedly provided with annular bristles, and the threaded rod is engaged with the inner side of the annular bristles.
[0013] As a further optimization of this utility model, a drain pipe is fixedly provided on the top side of the reactor body, and a cover plate can be detachably installed inside the feed inlet opened on the top of the reactor body.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. The micro-nano bubbles generated by the dissolved air pump, combined with photocatalytic materials and ultraviolet lamps, can purify wastewater. The reflector can reflect the light from the ultraviolet lamp to improve the illumination effect on the photocatalytic materials. The drive mechanism can move components such as the convex plate. After the convex plate moves, it can clean the surface of the reflector through the strip cleaning component and clean the surface of the quartz tube over a large area through the ring cleaning component. The cleaning process is more convenient and faster, and the reactor does not need to be stopped during cleaning, thus improving the purification efficiency.
[0016] 2. Driven by the motor inside the drive mechanism, and in conjunction with the rotation of the threaded rod, the convex plate and other components can be moved, which facilitates the cleaning of the surface of components such as the quartz tube. In addition, the annular bristles inside the fixing ring can brush away impurities and photocatalytic materials adhering to the surface of the threaded rod when the convex plate moves, so that impurities and photocatalytic materials are less likely to get stuck at the connection between the threaded rod and the convex plate, thereby improving the service life of the threaded rod and other components.

Detailed Implementation
[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0023] Example
[0024] like Figure 1-4 As shown, a reactor coupling micro / nano bubbles and a photocatalytic device includes a reactor body 1, a dissolved air pump 2, and a photocatalytic material 4. The dissolved air pump 2 is installed on the outside of the reactor body 1, and the photocatalytic material 4 is disposed inside the reactor body 1. Several quartz tubes 5 are installed inside the reactor body 1 in a staggered manner. An ultraviolet lamp 51 is fixedly installed inside the quartz tube 5. The quartz tube 5 is located inside the photocatalytic material 4. The quartz tube 5 can separate the wastewater in the reactor body 1 from the ultraviolet lamp 51, and the light from the ultraviolet lamp 51 can pass through the quartz tube 5 to irradiate the photocatalytic material 4, thereby carrying out a photocatalytic reaction. Several water distributors 21 are fixedly connected to the dissolved air pump 2 through water pipes. The water distributors 21 are fixedly disposed on the inner bottom of the reactor body 1. The photocatalytic material 4 can be photocatalyst particles or the like filled in the reactor body 1. This is a public technology and will not be described in detail here.
[0025] Wastewater can enter the dissolved air pump 2 through an external water pipe. The dissolved air pump 2 can add nano-microbubbles to the wastewater entering it and guide it into several water distributors 21 through water pipes. The several water distributors 21 can evenly send the wastewater containing nano-microbubbles into the reactor body 1, so that the wastewater coupled with nano-microbubbles can form sufficient contact with the photocatalytic material 4. Through contact with the wastewater with added nano-microbubbles, the nano-microbubbles can provide a large amount of dissolved oxygen, which can promote the generation of active free radicals in the photocatalytic process.
[0026] like Figure 2-3 As shown, a partition net 3 is fixedly installed inside the reactor body 1, and a reflector 31 is fixedly installed on the top of the partition net 3. Several through holes 32 are opened in the reflector 31. The partition net 3 is located above the water distributor 21, and the photocatalytic material 4 is located on the top of the reflector 31. The partition net 3 can support the reflector 31. The partition net 3 and the reflector 31 can separate the photocatalytic material 4 from the water distributor 21. The reflector 31 can reflect the light from the ultraviolet lamp 51 to improve the illumination effect on the photocatalytic material 4.
[0027] Wastewater at the bottom of reactor body 1 can pass through the mesh and through holes 32 of the partition 3 and enter the top of reactor body 1 to come into contact with photocatalytic material 4. The photocatalytic material 4 will descend due to its own gravity, while the upward lifting force of the nano-microbubbles and wastewater can make the photocatalytic material 4 float up and down to improve light transmittance.
[0028] like Figure 2-4 As shown, a cleaning mechanism is provided inside the reactor body 1. The cleaning mechanism includes a convex plate 6 that slides inside the reactor body 1, several annular cleaning components 61 that are fixedly installed in the circular holes opened in the convex plate 6, a strip-shaped cleaning component 62 that is fixedly installed at the bottom of the convex plate 6 and abuts against the top of the reflector 31, and a driving mechanism installed inside the reactor body 1 for driving the convex plate 6 to move. The annular cleaning components 61 abut against the outer wall of the quartz tube 5. The annular cleaning components 61 can be annular objects such as annular sponges that have a cleaning effect, and the strip-shaped cleaning components 62 can be long strip objects such as long strip sponges that have a cleaning effect. A drain pipe 11 is fixedly installed on the top of one side of the reactor body 1. The drain pipe 11 can discharge the purified wastewater inside the reactor.
[0029] After the drive mechanism drives the convex plate 6 to move, it can stir the photocatalytic material 4 in the reactor body 1, so that the photocatalytic material 4 can receive light more evenly, thereby carrying out photocatalytic reaction. After the convex plate 6 moves, it can also clean the surface of the reflector 31 through the strip cleaning component 62, and clean the surface of the quartz tube 5 over a large area through the annular cleaning component 61 to ensure the light transmission effect of the quartz tube 5. The impurities cleaned by the strip cleaning component 62 and the annular cleaning component 61 will be discharged from the drain pipe 11 with the wastewater.
[0030] like Figure 1-3 As shown, a cover plate is detachably installed inside the feed inlet at the top of the reactor body 1. The cover plate can be installed on the top of the reactor body 1 by means of a detachable connection such as a locking buckle. When the photocatalytic material 4 is replaced later, the cover plate can be removed from the feed inlet, and the new photocatalytic material 4 can be fed into the reactor body 1 through the feed inlet. A discharge pipe is fixedly installed on one side of the reactor body 1. One side of the discharge pipe is engaged with the reflector 31. When the photocatalytic material 4 is replaced, the photocatalytic material 4 on the top of the reflector 31 can be discharged through the discharge pipe.
[0031] like Figure 2-4 As shown, the driving mechanism includes a motor 7 fixedly mounted on the outer wall of the reactor body 1 and a threaded rod 71 fixedly mounted on the output end of the motor 7. The threaded rod 71 is rotatably mounted inside the reactor body 1. A convex plate 6 is threaded onto the outer wall of the threaded rod 71. The two sides of the convex plate 6 abut against the inner wall of the reactor body 1. A sealing element can be provided at the connection between the output end of the motor 7 and the reactor body 1. The motor 7 can rotate forward and reverse. This is a public technology and will not be described in detail here. The reactor body 1 can limit the convex plate 6, so that the convex plate 6 can only slide laterally inside the reactor body 1.
[0032] After the motor 7 is running, it will drive the threaded rod 71 to rotate. In conjunction with the limiting position of the reactor body 1, it will drive the convex plate 6 to move, thereby driving the annular cleaning component 61 and the strip cleaning component 62 to move accordingly.
[0033] like Figure 2-4 As shown, fixed rings 72 are fixed on both sides of the convex plate 6, and annular bristles 73 are fixed inside the fixed rings 72. The threaded rod 71 abuts against the inner side of the annular bristles 73. The annular bristles 73 are a number of bristles fixed in the fixed rings 72 and distributed in a ring. The annular bristles 73 inside the fixed rings 72 can brush away the impurities and photocatalytic material 4 attached to the surface of the threaded rod 71 when the convex plate 6 moves, so that the impurities and photocatalytic material 4 are not easily stuck at the connection between the threaded rod 71 and the convex plate 6.
[0034] It should be noted that, in the operation of this reactor that couples micro- and nano-bubbles with a photocatalytic device, wastewater is first fed into a dissolved air pump 2 through an external water pipe. The dissolved air pump 2 adds nano-microbubbles to the wastewater entering it and then guides it into several water distributors 21 through the water pipe. The water distributors 21 can evenly deliver the wastewater containing nano-microbubbles into the reactor body 1, allowing the wastewater containing nano-microbubbles to form sufficient contact with the photocatalytic material 4. The oxygen carried by the microbubbles is conducive to the photocatalytic material 4 generating more active free radicals, playing a synergistic role. The light generated by the ultraviolet lamp 51 can carry out a photocatalytic reaction. The pollutants adsorbed on the surface of the photocatalytic material 4 react and degrade with the active free radicals generated by the nano-microbubbles, thereby purifying the wastewater.
[0035] Furthermore, after the motor 7 starts running, it will drive the threaded rod 71 to rotate. In conjunction with the limiting position of the reactor body 1, it will drive the convex plate 6 to move. After the convex plate 6 moves, it can stir the photocatalytic material 4 inside the reactor body 1, so that the photocatalytic material 4 can receive light more evenly, thereby carrying out the photocatalytic reaction. After the convex plate 6 moves, it can also clean the surface of the reflector 31 through the strip cleaning component 62, and can also clean the surface of the quartz tube 5 over a large area through the annular cleaning component 61. The cleaning process is more convenient and faster, and there is no need to stop the reactor during cleaning, thus improving the purification efficiency.
[0036] The annular bristles 73 inside the fixed ring can brush away impurities and photocatalytic material 4 adhering to the surface of the threaded rod 71 when the convex plate 6 moves, making it less likely for impurities and photocatalytic material 4 to get stuck at the connection between the threaded rod 71 and the convex plate 6, thereby improving the service life of the threaded rod 71 and other components.
[0037] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
