Description

Technical Field

[0001] This invention relates to the field of wastewater recycling technology, specifically to a reverse osmosis primary concentrate recycling and reuse device. Background Technology

[0002] Primary concentrate refers to high-salinity wastewater generated during reverse osmosis (RO) desalination. Reverse osmosis is a highly efficient separation technology mainly used to remove dissolved salts and microorganisms from water. In this process, water passes through a semi-permeable membrane, while salts and other macromolecules are retained, thus producing high-salinity concentrate.

[0003] For example, Chinese invention CN202411538572.5 discloses a recycling device for effluent from an RO concentrate system, including a buffer tank, which is connected to an ultrafiltration device, which is connected to a precision filter, which is connected to an RO device, which is connected to a nanofiltration device, and the RO device is also connected to a product water tank. The concentrate is filtered by the RO device and then separated into two streams of product water, one of which is recycled water. The recycled water enters the product water tank after the conductivity and flow rate of the product water are tested. The failure or shutdown of this device will not affect the normal operation of the main equipment.

[0004] In applications such as steel plant circulating cooling water systems, a large amount of concentrated water is discharged. To save water resources, reverse osmosis devices are generally used to treat the circulating water discharge. However, the concentrated water obtained after reverse osmosis desalination cannot be directly recycled and needs to undergo multi-stage treatment processes to gradually remove pollutants and adjust the water quality, ultimately achieving secondary utilization of water resources. In the multi-stage treatment process of primary concentrated water from reverse osmosis, the first step is to soften the concentrated water, which involves adding a pre-mixed lime slurry and soda ash solution to soften the primary concentrated water.

[0005] During the softening process of primary concentrate by adding a pre-mixed lime slurry and soda ash solution to the concentrate, when the amount of concentrate discharged from the cooling water system increases, the conventional stirring method in the reactor cannot guarantee that the primary concentrate of reverse osmosis reacts fully with the pre-mixed lime slurry and soda ash solution to soften it. This results in the primary concentrate recycling unit of reverse osmosis needing to wait for a long processing time during the softening process, reducing the working efficiency of the unit.

[0006] Furthermore, during the softening process of the first-stage concentrate of reverse osmosis, precipitates (calcium carbonate and magnesium hydroxide) are generated. These precipitates aggregate together during the reaction and easily form viscous precipitates that adhere to the inner wall of the reactor. If they are not cleaned in time, they will affect the softening effect of the first-stage concentrate of reverse osmosis, thereby reducing the quality of the secondary water recovered later.

[0007] Therefore, there is an urgent need for a reverse osmosis primary concentrate water recycling and reuse device to solve the above problems. Summary of the Invention

[0018] Preferably, the driving component includes a rotating shaft that is rotatably connected to the lower surface of the reactor, and a complete gear that meshes with the incomplete gear is fixedly connected to the surface of the rotating shaft.

[0019] It also includes a rack and pinion that meshes with the incomplete gear and the complete gear. A limiting block is fixedly connected to the upper surface of the rack and pinion.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] I. This invention achieves precise monitoring and intelligent response of the concentrated water flow rate in the inlet pipe through the coordinated operation of multiple structures. When the concentrated water flow rate is high, the annular stirring rod is driven to rotate and reciprocate vertically within the reactor, agitating the concentrated water from top to bottom. This allows for better mixing of the concentrated water with lime slurry and soda ash solution, resulting in a more complete softening reaction. Compared to traditional fixed stirring methods, this invention significantly shortens the softening time and improves the concentrated water treatment efficiency, thus meeting the requirements for high-flow-rate concentrated water recycling. Furthermore, when the concentrated water flow rate is low, the device can automatically switch to a normal rotary stirring mode, avoiding unnecessary energy consumption and reducing wear on the internal structure of the reverse osmosis primary concentrated water recycling device. This invention is worthy of promotion and application.

[0027] Second, this invention can drive the striking block to reciprocate against the outer wall of the reactor when the concentrated water flow rate is high through the linkage of multiple structures. This mechanical vibration can quickly shake off the viscous substances adhering to the inner wall of the reactor, further improving the softening effect of the first-stage concentrated water of reverse osmosis, and also improving the quality of the secondary reuse water obtained after subsequent recovery. It can also keep the reactor clean and operate efficiently. The intelligent linkage between the striking block and the concentrated water flow rate ensures that the striking block only reciprocates against the reactor when the concentrated water flow rate is high, achieving effective protection of the internal structure of the device and extending the service life of the reverse osmosis first-stage concentrated water recycling and reuse device.

[0048] It also includes a rack 19 that meshes with the incomplete gear 30 and the complete gear 22. A limiting block 18 is fixedly connected to the upper surface of the rack 19. A limiting groove 20 is provided on the lower surface of the reactor 1 for the limiting block 18 to extend and slide. An oil filling port 29 is provided on the surface of the drive box 7.

[0049] A sleeve 17 is slidably connected to the surface of the reactor 1. An installation plate 48 is fixedly installed on the lower surface of the drive box 7. A rotating shaft 11 is rotatably connected to the surface of the installation plate 48. A belt pulley transmission mechanism 10 is provided between the rotating shaft 11 and the rotating rod 9.

The sleeve 17 is sleeved on the outer surface of the plurality of arc-shaped protrusions 15 and the rotating shaft 11. An annular stirring rod 16 is fixedly installed at one end of the sleeve 17 that extends into the reactor 1.

[0050] The surface of the sleeve 17 is rotatably connected to a movable block 25, the surface of the movable block 25 is hinged to a hinge rod 26, the surface of the rack 19 is hinged to a hinge plate 21, and the end of the hinge plate 21 away from the rack 19 is hinged to the hinge rod 26.

[0051] A spring pad 23 is fixedly installed on the lower surface of the reactor 1, and a spring 24 is provided between the spring pad 23 and the moving block 25.

[0052] More specifically, in the embodiments:

[0053] like Figure 1 and Figure 2 As shown, reverse osmosis primary concentrate is introduced into reactor 1 through inlet pipe 2 via the diversion pipe. The prepared lime slurry and soda ash solution are poured into reactor 1 through feed pipe 4 and feed pipe 5. The reverse osmosis primary concentrate will then undergo softening treatment in reactor 1.

[0054] like Figure 2 , Figure 4 and Figure 8 As shown, as the first-stage concentrated water from reverse osmosis flows into the inlet pipe 2, when the concentrated water flow rate is small, the water flow will drive the impeller 32 to rotate at a small speed, and drive the rotating rod 9 to rotate. Under the action of the belt pulley transmission mechanism 10, the rotating shaft 11 will rotate synchronously. Since the sleeve 17 is sleeved on the outer surface of multiple arc-shaped protrusions 15 and the rotating shaft 11, the rotation of the rotating shaft 11 will drive the sleeve 17 to rotate synchronously, thereby causing the annular stirring rod 16 in the reactor 1 to start rotating. Under the action of the annular stirring rod 16, a swirling flow can be generated in the reactor 1. The swirling flow generates centrifugal force, and the high-density concentrated water that is not fully softened is thrown to the periphery. The low-density concentrated water that is fully softened will rise to the central area. When the softened low-density concentrated water rises to the same height as the overflow port 14, it will enter the water storage frame 6 through the overflow port 14 and finally be discharged through the outlet pipe 3 on the surface of the water storage frame 6 for the next treatment process.

[0055] When the flow rate of concentrated water in the inlet pipe 2 increases, the amount of concentrated water entering the reactor 1 for softening increases. At this time, the ring stirring rod 16 rotates only around the sleeve 17 as the axis, which makes it difficult for the first stage of reverse osmosis concentrated water to fully react and soften with the well-proportioned lime milk and soda ash solution.

[0056] like Figure 4 , Figure 5 and Figure 6 As shown, as the flow rate of concentrated water in the inlet pipe 2 increases, the water flow will drive the impeller 32 to rotate at a higher speed, so that the rotation speed of the rotating rod 9 increases. As the rotation speed of the rotating rod 9 increases, the rotation speed of the turntable 35 increases. At this time, the centrifugal force on the two moving blocks 34 is greater than the elastic force of the spring 40. Therefore, the two moving blocks 34 will extend out of the rectangular slot 37. As the turntable 35 rotates, when the two moving blocks 34 abut against the abutting block 36, they will drive the abutting block 36 and the circular shell 31 to rotate synchronously, and drive the incomplete gear 30 below to rotate.

[0057] like Figure 7 As shown, with the rotation of the incomplete gear 30, the rack 19 will first move to the left. The movement of the rack 19 will then cause the complete gear 22 to rotate counterclockwise. When the incomplete gear 30 disengages from the rack 19, it will mesh with the complete gear 22 and cause the complete gear 22 to rotate clockwise to reset. As the complete gear 22 rotates clockwise, the rack 19 will also move to the right to reset. That is, with the rotation of the incomplete gear 30, the rack 19 will reciprocate in the horizontal direction.

[0058] like Figure 8 As shown, with the reciprocating movement of the rack 19, under the hinge action of the hinge plate 21, the moving block 25 drives the sleeve 17 to reciprocate vertically. This allows the annular stirring rod 16 on the surface of the sleeve 17 to reciprocate vertically within the reactor 1 while rotating with the sleeve 17. This disturbs the concentrated water in the reactor 1 from top to bottom, allowing it to mix better with the lime slurry and soda ash solution, making the softening reaction more complete, shortening the softening time of the concentrated water, and enhancing the working efficiency of the reverse osmosis primary concentrated water recycling and reuse device.

[0059] Example 2, based on the above examples,

[0060] Furthermore, the striking component in Embodiment 1 is disclosed. The striking component includes a limiting frame 41 fixedly installed on the surface of the drive box 7. A rotating shaft 28 passes through the limiting frame 41 and is rotatably connected to it. A moving block 43 is slidably connected to the inner wall of the limiting frame 41. A rotating plate 27 is fixedly connected to the surface of the rotating shaft 28. A hinge plate 42 is hinged to the end of the rotating plate 27. The end of the hinge plate 42 is hinged to the moving block 43. A rectangular slot 44 is opened on the surface of the moving block 43.

[0061] Two symmetrically arranged fixed plates 47 are fixedly connected to the surface of the reactor 1. The two fixed plates 47 are rotatably connected to a common fixed axis by a hinge rod 45. The two fixed plates 47 are hinged to a swing rod 46 through the hinge rod 45. One end of the swing rod 46 is fixedly connected to the striking block 12, and the other end of the swing rod 46 extends into the rectangular slot 44 and is slidably connected to it.

[0062] More specifically, in this embodiment:

[0063] like Figure 8 , Figure 9 and Figure 10 As shown, when the flow rate of concentrated water in the inlet pipe 2 increases, the rotation of the incomplete gear 30 causes the complete gear 22 and the rotating shaft 28 to reciprocate. The reciprocating rotation of the rotating shaft 28 drives the rotating plate 27 to reciprocate. Under the hinge action of the hinge plate 42, the reciprocating rotation of the rotating plate 27 drives the moving block 43 to reciprocate horizontally within the limiting frame 41. Since the fixed plate 47 is hinged to the swing rod 46 through the hinge rod 45, and the end of the swing rod 46 without the striking block 12 extends into the rectangular slot 44 and slides therewith, the reciprocating movement of the moving block 43... This causes the swing rod 46 to swing back and forth around the hinge rod 45, which in turn causes the striking block 12 at the end of the swing rod 46 to repeatedly strike the outer wall of the reactor 1, causing it to vibrate. When the vibration is transmitted to the inner wall of the reactor 1, it can shake off the viscous precipitate attached to the inner wall of the reactor 1, thus preventing the accumulation of viscous material in the reactor and keeping the reactor clean and operating efficiently. This helps to reduce equipment failure and efficiency decline caused by the accumulation of viscous material, thereby reducing maintenance costs and downtime, and further improving the working efficiency of the reverse osmosis primary concentrate recovery and reuse unit.

[0064] It is worth noting that when the flow rate of concentrated water in the inlet pipe 2 is small, the centrifugal force on the two moving blocks 34 is less than the elastic force of the spring 40. Therefore, the annular stirring rod 16 will not reciprocate within the reactor 1, nor will the striking block 12 operate. In other words, the sensing component can monitor the flow rate of concentrated water in the inlet pipe in real time and automatically control the working state of the drive component and the striking component according to the flow rate. This ensures that the annular stirring rod 16 will only move vertically within the reactor 1 when the flow rate of concentrated water in the inlet pipe 2 increases, and the striking block 12 will only reciprocate and strike the reactor 1 when the flow rate of concentrated water in the inlet pipe 2 increases. This reduces wear on the internal structure of the device and extends its service life.

[0065] Working principle: A reverse osmosis primary concentrate water recycling and reuse device. In use, reverse osmosis primary concentrate water is introduced into reaction vessel 1 through inlet pipe 2 via diversion pipe, and lime milk and soda ash solution are poured into reaction vessel 1 through feed pipe 2 4 and feed pipe 1 5 so that the reverse osmosis primary concentrate water is softened in reaction vessel 1.

[0066] When the concentrated water flow rate is low, the water flow will drive the impeller 32 to rotate at a low speed. Under the action of the belt pulley transmission mechanism 10, the rotating rod 9 and the rotating shaft 11 will rotate synchronously, so that the sleeve 17 will drive the annular stirring rod 16 in the reactor 1 to rotate. Under the action of the annular stirring rod 16, a swirling flow is generated in the reactor 1. The swirling flow generates centrifugal force, which throws the insufficiently softened high-density concentrated water to the periphery, while the fully softened low-density concentrated water will rise to the central area. When the softened low-density concentrated water rises to the same height as the overflow port 14, it will enter the water storage frame 6 through the overflow port 14 and finally be discharged through the water outlet pipe 3 on the surface of the water storage frame 6 for the next treatment process.

[0067] When the flow rate of concentrated water in the inlet pipe 2 increases, the water flow will drive the impeller 32 to rotate at a higher speed. As the rotation speed of the rotating rod 9 increases, the centrifugal force on the two moving blocks 34 is greater than the elastic force of the spring 40. The two moving blocks 34 will extend out of the rectangular slot 37. When the two moving blocks 34 abut against the abutting block 36, they will drive the abutting block 36 and the circular housing 31 to rotate synchronously, and drive the incomplete gear 30 below to rotate, so that the rack row 19 will reciprocate in the horizontal direction. Under the hinge action of 21, the moving block 25 will drive the sleeve 17 to move back and forth in the vertical direction. This allows the annular stirring rod 16 on the surface of the sleeve 17 to move back and forth in the vertical direction in the reactor 1 while the sleeve 17 rotates. This can disturb the concentrated water in the reactor 1 from top to bottom, so that the concentrated water can be better mixed with lime milk and soda ash solution, making the softening reaction more complete, shortening the softening time of the concentrated water, and enhancing the working efficiency of the reverse osmosis first-stage concentrated water recycling and reuse device.

[0068] As the incomplete gear 30 rotates, it also drives the complete gear 22 to rotate reciprocally. Under the hinge action of the hinge plate 42, it drives the moving block 43 to move reciprocally in the horizontal direction within the limiting frame 41, so that the swing rod 46 swings reciprocally. This causes the striking block 12 at the end of the swing rod 46 to strike the outer wall of the reactor 1 reciprocally. When the vibration is transmitted to the inner wall of the reactor 1, it can shake off the viscous precipitate attached to the inner wall of the reactor 1, so as to avoid the accumulation of viscous material in the reactor, ensuring the cleanliness and efficient operation of the reactor. This reduces the device failure and efficiency decline caused by the accumulation of viscous material, reduces maintenance costs and downtime, and further improves the working efficiency of the reverse osmosis primary concentrated water recycling and reuse device. It is worth promoting and using.
