Description

Technical Field

[0001] The present application relates to the technical field of wastewater treatment, and in particular to a wastewater treatment device and a wastewater treatment system. Background Art

[0002] Battery electrolytes primarily consist of electrolyte salts and organic solvents, including dimethyl carbonate, ethyl methyl carbonate, and ethylene carbonate. During the battery recycling process, organic wastewater is inevitably generated. A commonly used treatment process for this wastewater is ozone catalytic oxidation, which offers numerous advantages, including fast reaction speed, no secondary pollution, a short process flow, and ease of operation.

[0003] Ozone, under the action of a catalyst, forms hydroxyl radicals (-OH). Hydroxyl radicals (-OH) react with organic matter at a higher rate and are more oxidizing, capable of oxidizing almost all organic matter. Furthermore, catalysts can catalyze ozone to directly oxidize organic matter in water into carbon dioxide (CO2) and water (H2O), or to oxidize large organic molecules into smaller ones, making them more susceptible to degradation.

[0004] However, the contact area between the catalyst in the related art and the wastewater mixed with ozone is small, which affects the oxidation efficiency and leads to low wastewater treatment efficiency. Utility Model Content

[0047] like Figure 1 As shown, an embodiment provides a wastewater treatment device 1000 that can be used to recycle electrolyte from waste batteries.

[0048] In other embodiments, the wastewater treatment equipment 1000 can also be used to treat industrial wastewater, domestic wastewater, etc.

[0049] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the wastewater treatment equipment 1000 includes a reaction tank 100 , a driving assembly 200 and at least one box body 300 .

[0050] The reaction tank 100 is equipped with a first accommodating chamber 110 for accommodating wastewater to be treated, wherein the wastewater may be mixed with ozone.

[0051] The drive assembly 200 may include a drive member 210 and a transmission shaft 220. The drive member 210 is fixedly mounted on a side of the reaction tank 100 away from the first accommodating chamber 110, i.e., the drive member 210 is disposed outside the reaction tank 100. The transmission shaft 220 is rotatably mounted in the reaction tank 100 and is in transmission connection with the drive member 210, and can be driven by the drive member 210 to rotate the drive shaft 220.

[0052] The at least one housing 300 is connected to the transmission shaft 220. When the drive member 210 rotates the transmission shaft 220, the at least one housing 300 is driven to rotate synchronously. In this embodiment, the housing 300 is configured with a second chamber 310 for holding the catalyst. Furthermore, at least one side of the housing 300 is provided with a through hole 3211 connecting the first chamber 110 and the second chamber 310. This allows wastewater in the first chamber 110 to enter the second chamber 310 and come into contact with the catalyst.

[0053] In the present application, the cartridge 300 for containing the catalyst is rotatably mounted in the reaction tank 100 and can be driven to rotate by the drive assembly 200. This increases the contact area between the ozone-mixed wastewater and the catalyst in the cartridge 300, allowing the ozone-mixed wastewater to fully contact the catalyst, thereby increasing the reaction rate of the wastewater treatment and improving the wastewater treatment efficiency.

[0054] like Figure 1 As shown, the reactor 100 further includes a first end 101 and a second end 102. The first end 101 may be located below the second end 102 in the direction of gravity. In an embodiment, the first end 101 of the reactor 100 is further connected to a support leg 920. The support leg 920 may be supported between the reactor 100 and a placement surface, providing support for the reactor 100. The placement surface may be a structure such as the ground.

[0055] like Figure 1 and Figure 2 The reaction tank 100 is further connected to a water inlet pipe 710 and a drain pipe 720, both of which are in communication with the first accommodating chamber 110. In some embodiments, the water inlet pipe 710 can be disposed near the second end 102 of the reaction tank 100. The drain pipe 720 can be disposed near the first end 101 of the reaction tank 100.

[0056] During use, wastewater can be injected into the reaction tank 100 from the water inlet pipe 710 and can move toward the drain pipe 720 under the action of gravity. In an embodiment, the treated wastewater can be discharged from the reaction tank 100 through the drain pipe 720.

[0057] In some embodiments, a control valve (not shown) is further provided on the drain pipe 720, which can be used to control the on / off state of the drain pipe 720, so as to control whether the treated wastewater in the reaction tank 100 is discharged. In some embodiments, the control valve can be a solenoid valve, which can realize automatic control of the on / off state of the drain pipe 720.

[0058] In other embodiments, the control valve may also be a manual valve.

[0059] like Figures 1 to 3As shown, the wastewater treatment equipment 1000 further includes an ozone generator 400 and a diverter 500. The ozone generator 400 can be disposed on a side of the reaction tank 100 away from the first accommodating chamber 110, i.e., the ozone generator 400 is disposed outside the reaction tank 100. In some embodiments, the ozone generator 400 can be disposed near the first end 101 of the reaction tank 100 and can be placed on the same placement plane as the support legs 920.

[0060] The diverter 500 can be disposed within the reaction tank 100, and the diverter 500 can be disposed near the first end 101 of the reaction tank 100. In an embodiment, the diverter 500 can include a plurality of air inlet holes 510, each of which has one end connected to the first accommodating chamber 110. Furthermore, the other ends of the plurality of air inlet holes 510 can be connected to the ozone generator 400 via a first transmission pipe 810.

[0061] During use, the ozone generator 400 can be used to generate ozone and can be used to deliver the ozone to the diverter 500 through the first transmission pipe 810. The diverter 500 can divide the ozone delivered by the first transmission pipe 810 into multiple airflows and deliver them to the first accommodating chamber 110 so that the ozone is mixed with the wastewater. In an embodiment, dividing the ozone into multiple airflows and entering the first accommodating chamber 110 can increase the contact area between the ozone and the wastewater, allowing the ozone and the wastewater to be fully mixed, thereby improving the wastewater treatment efficiency. At the same time, the utilization rate of the ozone can also be increased. It is understandable that the ozone in the wastewater can be mixed after the wastewater enters the reaction tank 100.

[0062] In other embodiments, wastewater mixed with ozone may be directly injected into the reaction tank 100 through the water inlet pipe 710 .

[0063] Furthermore, the diverter 500, located at the first end 101 of the reaction tank 100, allows ozone to enter from the bottom of the reaction tank 100. This prolongs the ozone flow path within the wastewater, allowing for sufficient contact and reaction between the ozone and the wastewater. This improves wastewater treatment efficiency and further increases ozone utilization.

[0064] like Figure 2 、 Figure 3 and Figure 6As shown, in some embodiments, the diverter 500 may be in the shape of a round block. The diverter 500 may be coaxially arranged with the reaction tank 100, that is, the central axis of the diverter 500 coincides with the central axis of the reaction tank 100. A plurality of air inlet holes 510 may be distributed around the diverter 500, and the plurality of air inlet holes 510 may be radially extended along the radial direction of the diverter 500. The end of the first transmission tube 810 away from the ozone generator 400 may be inserted into the diverter 500 and communicate with the end of the plurality of air inlet holes 510 close to the central axis of the diverter 500. The end of the air inlet hole 510 away from the first transmission tube 810 may be arranged toward the side wall of the peripheral side of the reaction tank 100 and communicate with the first accommodating chamber 110.

[0065] In other embodiments, the diverter 500 may also be a rod-shaped structure, a square structure, a cross structure, or the like.

[0066] When ozone passes through the diverter 500 and enters the first accommodating chamber 110, each ozone gas flow can be roughly ejected outward along the radial direction of the diverter 500, thereby allowing the ozone to be dispersed in all directions of the first accommodating chamber 110, thereby increasing the contact area between ozone and wastewater, allowing the ozone and wastewater to be fully mixed, and improving the wastewater treatment efficiency.

[0067] In other embodiments, the plurality of air inlet holes 510 may also be provided along the axial direction of the flow dividing member 500. Accordingly, the end of the air inlet hole 510 away from the first transfer pipe 810 may be provided toward the second end 102 of the reaction tank 100.

[0068] In this embodiment, the first transmission tube 810 can be a rigid tube such as a metal tube or a relatively rigid plastic tube. The end of the first transmission tube 810 remote from the ozone generator 400 is inserted through the reaction tank 100, and the refrigerator is provided with a protruding bottom portion of the reaction tank 100. The diverter 500 can be fixedly mounted on the end of the first transmission tube 810 remote from the ozone generator 400. Accordingly, the first transmission tube 810 can provide support for the diverter 500.

[0069] Furthermore, a support plate 911 is fixedly connected to one end of the first transmission tube 810 near the diverter 500. The support plate 911 can be located on a side of the diverter 500 away from the second end 102, and can be spaced apart from and opposite the diverter 500. In this embodiment, a plurality of support rods 912 are connected between the support plate 911 and the diverter 500. The plurality of support rods 912 can be evenly distributed along the circumference of the diverter 500. This improves the installation stability of the diverter 500.

[0070] like Figure 1 and Figure 2As shown, the wastewater treatment equipment 1000 further includes an exhaust pipe 730. The exhaust pipe 730 can be fixedly mounted at the second end 102 of the reaction tank 100 and can communicate with the first accommodating chamber 110. In one embodiment, the end of the exhaust pipe 730 remote from the first accommodating chamber 110 can communicate with an ozone collection device. The exhaust pipe 730 can be used to discharge excess ozone from the reaction tank 100, thereby reducing ozone leakage and preventing environmental pollution caused by ozone leakage.

[0071] During use, ozone entering the first accommodating chamber 110 moves from the first end 101 to the second end 102 of the reaction tank 100 under the action of buoyancy. During this process, some ozone will react with the wastewater and be consumed, while some ozone will reach the second end 102 of the reaction tank 100 and be discharged through the exhaust pipe 730 to be collected by the ozone collection device.

[0072] like Figure 1 and Figure 2 As shown, in some embodiments, the driving member 210 can be a motor. The driving member 210 can be fixedly mounted on the top of the reaction tank 100. In addition, the output shaft of the driving member 210 can be disposed through the reaction tank 100 and extend into the first accommodating chamber 110 to be in transmission connection with the transmission shaft 220.

[0073] In some embodiments, the transmission shaft 220 may be parallel to the axial direction of the reaction tank 100. Furthermore, the rotation axis of the transmission shaft 220 may also be parallel to the axial direction of the reaction tank 100. In some embodiments, the transmission shaft 220 may extend from the second end 102 to the first end 101 of the reaction tank 100 and generally extend to a position near the diverter 500. A relatively small distance may exist between the transmission shaft 220 and the diverter 500.

[0074] like Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments, the wastewater treatment equipment 1000 may include three cartridges 300 for containing catalysts. The drive assembly 200 may also include a sleeve 240. The sleeve 240 may be fixedly mounted on the drive shaft 220, thereby driving the sleeve 240 to rotate synchronously with the drive shaft 220. The three cartridges 300 are each connected to the side of the sleeve 240 away from the drive shaft 220 and may be evenly distributed along the circumference of the sleeve 240.

[0075] In other embodiments, the wastewater treatment equipment 1000 may also include one, two, four, or five boxes 300. When the wastewater treatment equipment 1000 includes multiple boxes 300, the multiple boxes 300 may be evenly or unevenly distributed along the circumference of the sleeve 240.

[0076] In other embodiments, the box body 300 may also be directly fixedly connected to the transmission shaft 220 .

[0077] like Figure 2 、 Figure 4 and Figure 5 As shown, the box body 300 may include multiple enclosing panels 320. Specifically, the box body 300 may include two first enclosing panels 321, two third enclosing panels 323, and one second enclosing panel 322. The second enclosing panel 322 may be spaced apart and opposite to the sleeve 240. The two first enclosing panels 321 may be spaced apart and opposite to each other, and the two third enclosing panels 323 may be spaced apart and opposite to each other. Accordingly, the two first enclosing panels 321, the two third enclosing panels 323, the second enclosing panel 322, and the sleeve 240 may cooperate to form a second accommodating chamber 310 for holding the catalyst. The box body 300 may generally have a square structure.

[0078] In some embodiments, the transmission shaft 220 is configured with a rotation direction M. The rotation direction M can be clockwise or counterclockwise. The two first enclosing plates 321 can be arranged sequentially along the rotation direction M. In this embodiment, each of the two first enclosing plates 321 has a through hole 3211 that connects the first accommodating cavity 110 and the second accommodating cavity 310.

[0079] During use, when the drive assembly 200 rotates the cartridge body 300 containing the catalyst, wastewater can enter the second accommodating chamber 310 through the through-hole 3211 on the first enclosing plate 321 that moves forward, and then can be discharged through the through-hole 3211 on the first enclosing plate 321 that moves backward. In other words, wastewater can pass through the cartridge body 300 and come into contact with the catalyst.

[0080] In other embodiments, the second enclosing plate 322 and / or the third enclosing plate 323 may also be provided with a through hole 3211 communicating with the first accommodating cavity 110 and the second accommodating cavity 310 .

[0081] In some embodiments, the first enclosing plate 321 can be tilted relative to the axial direction of the transmission shaft 220. This increases the contact area between the first enclosing plate 321 and the wastewater, improving the flow rate of the wastewater in the box body 300. Furthermore, the catalyst can be fully contacted with the wastewater, thereby improving the wastewater treatment efficiency.

[0082] In some embodiments, the second enclosing plate 322 can be detachably mounted relative to the first enclosing plate 321 and the third enclosing plate 323. For example, the second enclosing plate 322 can be detachably connected to the first enclosing plate 321 and the third enclosing plate 323, respectively, by screws or snaps. This facilitates replacement of the catalyst in the cartridge 300, ensuring a smooth catalytic reaction between ozone and wastewater and ensuring effective wastewater treatment.

[0083] In other embodiments, a first enclosing plate 321 or a third enclosing plate 323 may be configured to be detachable to facilitate replacement of the catalyst in the box body 300. Alternatively, two or three enclosing plates 320 may be configured to be detachable at the same time.

[0084] like Figure 2 As shown, the drive assembly 200 also includes a stirring blade 230. The stirring blade 230 can be fixedly connected to the transmission shaft 220. When the driving member 210 drives the transmission shaft 220 to rotate, the stirring blade 230 can be driven to rotate synchronously to stir the wastewater in the reaction tank 100 so that the wastewater and ozone are fully contacted and reacted. In some embodiments, the stirring blade 230 can be arranged on a side of the box body 300 close to the diverter 500, and the stirring blade 230 can be arranged close to the end of the transmission shaft 220 away from the driving member 210.

[0085] In some embodiments, the stirring blade 230 can be a spiral blade.

[0086] In other embodiments, the stirring blade 230 may also be a structure of multiple blades.

[0087] like Figure 1 and Figure 2 As shown, the wastewater treatment equipment 1000 further includes a water pump 600, the water inlet of the water pump 600 can be connected to the first end 101 of the reaction tank 100 through the second transmission pipe 820. The water outlet of the water pump 600 can be connected to the second end 102 of the reaction tank 100 through the third transmission pipe 830.

[0088] During use, the water pump 600 can pump wastewater from the first end 101 of the reaction tank 100, transport it to the second end 102 of the reaction tank 100, and inject it back into the reaction tank 100 from the second end 102. This can increase the contact between the wastewater and the ozone, allowing the wastewater to fully contact and react with the sample, thereby improving the wastewater treatment effect.

[0089] When the wastewater treatment equipment 1000 treats wastewater, the wastewater can be injected into the reaction tank 100 through the water inlet pipe 710. The driving member 210 and the ozone generator 400 are started, and the ozone generated by the ozone generator 400 can enter the reaction tank 100 in turn through the diverter 500, so that the ozone can contact and react with the wastewater in the reaction tank 100. The driving member 210 can drive the transmission shaft 220 to rotate, and drive the box body 300 containing the catalyst and the stirring blade 230 to rotate synchronously. The catalyst in the box body 300 can fully contact with the wastewater to catalyze the reaction between ozone and wastewater. In addition, the first enclosing plate 321 opened in the through hole 3211 of the box body 300 is tilted to further increase the contact area between the catalyst and the wastewater, so that the wastewater and the catalyst are fully in contact. The stirring blade 230 can stir the wastewater so that the wastewater and the ozone are fully in contact, so as to improve the reaction efficiency of ozone and wastewater and improve the treatment effect of the wastewater. Specifically, the coordination of agitator blades 230 and catalyst cartridge 300 effectively increases the efficiency of the ozone-wastewater reaction, improving wastewater treatment. Furthermore, water pump 600 can be activated to circulate the wastewater within reaction tank 100, allowing it to fully interact with the ozone and further enhance wastewater treatment. The control valve on drain pipe 720 can be opened continuously or intermittently to drain the treated wastewater from reaction tank 100.

[0090] The embodiment further provides a wastewater treatment system, which may include a wastewater supply device, a recovery device, and a wastewater treatment device 1000 as provided in the embodiment. The wastewater supply device may be connected to the water inlet pipe 710 of the reaction tank 100, and the recovery device may be connected to the drain pipe 720 of the reaction tank 100.

[0091] In other embodiments, the wastewater treatment system may further include a filtering device, etc., which may be disposed between the wastewater supply device and the reaction tank 100 to filter the wastewater and remove solid debris in the wastewater.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0093] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application.
