Description

Technical Field

[0001] This invention relates to the field of environmental wastewater treatment technology, specifically an anaerobic reactor with anti-deposition function. Background Technology

[0002] Anaerobic biological treatment technology is widely used in the field of agricultural non-point source pollution treatment because it can efficiently treat high-concentration organic wastewater and generate biogas energy. Taking top-flow anaerobic sludge bed and expanded granular sludge bed as examples, the core of efficient and stable operation lies in maintaining a high concentration of highly active anaerobic sludge particles in the reaction zone and ensuring that the wastewater and sludge can be fully and uniformly contacted and mixed. However, existing anaerobic reactors still have some technical problems.

[0003] Firstly, traditional water distribution systems often use fixed inlet pipes or perforated pipes with fixed opening positions. Over long-term operation, the wastewater coverage area and upward flow pattern tend to become fixed, easily forming short-circuiting, channeling, or hydraulic dead zones at the bottom of the reactor. This leads to uneven wastewater diffusion and insufficient local expansion of the sludge bed, preventing organic matter in the wastewater from fully contacting the sludge microorganisms, reducing mass transfer efficiency and substrate degradation rate, and affecting the reactor's treatment capacity and effectiveness. Secondly, over long-term operation, some inert substances, inorganic salts, or aged biological sludge inevitably accumulate at the bottom of the reactor. Traditional reactors often have static sedimentation zones at the bottom, lacking active sludge removal design. The continuous accumulation of these deposits not only reduces the effective reaction volume but may also cause local acidification and accumulation of toxic substances, inhibiting microbial activity and leading to a decline in reactor performance. Summary of the Invention

[0004] The purpose of this invention is to provide an anaerobic reaction device with anti-deposition function to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anaerobic reactor with anti-deposition function, comprising a reaction tank, an overflow trough, a packing plate, a three-phase separator, a bottom plate, a nacelle shell, and a frame plate. The bottom plate is located at the bottom of the reaction tank, the overflow trough is located at the top of the reaction tank, a drain pipe is connected below the overflow trough, and an exhaust pipe is connected above the overflow trough. The packing plate and the three-phase separator are arranged inside the reaction tank from bottom to top. The frame plate is integrally formed with the bottom plate, the nacelle shell is located below the bottom plate, and an integrated water inlet cleaning assembly is installed on the bottom plate. The lower part of the component is connected to a sewage inlet pipe and a pumping pipe, which penetrate the engine compartment shell. One end of the pumping pipe is connected to a suction pump, and the other end of the sewage inlet pipe is connected to a sewage tank. The pumping pump on the sewage inlet pipe draws the sewage from the sewage tank into the inner adapter. The sewage then enters the distribution pipe and flows into the reaction tank through the drain pipe on the distribution pipe. After passing through the packing plate, the sewage reacts and decomposes. After separation and isolation by the three-phase separator, the treated water and gas rise, the sludge settles, and the treated water and gas enter the overflow tank. The treated water is discharged from the drain pipe, and the gas is discharged from the exhaust pipe.

[0006] Furthermore, the integrated water inlet and cleaning assembly includes a jacketed sleeve, a distribution pipe, an outer adapter, and an inner adapter. The jacketed sleeve penetrates the base plate and the frame plate, and is rotatably and sealingly connected to the base plate. The distribution pipe is installed inside the jacketed sleeve, and the bottom of the jacketed sleeve is rotatably and sealingly connected to the outer adapter. The bottom of the distribution pipe is also rotatably and sealingly connected to the inner adapter. The inner adapter is located below the outer adapter. The sewage inlet pipe is connected to the interior of the inner adapter, and the pumping pipe is connected to the interior of the outer adapter. During sewage treatment, the motor drives the worm gear to rotate, and the worm gear drives the worm wheel to rotate. Changing the rotation direction of the motor can change the rotation direction of the worm wheel. The worm wheel drives the jacketed sleeve and the distribution pipe to rotate. Since the outer adapter is rotatably and sealingly connected to the jacketed sleeve, and the distribution pipe is also rotatably and sealingly connected to the inner adapter, even when the jacketed sleeve and the distribution pipe are rotating, the inner adapter can still input sewage into the distribution pipe, and the pumping pipe can also pump sludge from the jacketed sleeve.

[0007] Furthermore, the integrated water inlet cleaning component includes several serrated scrapers and several perforated pipes. The serrated scrapers are arranged on the interlayer sleeve in a ring-shaped even distribution and are in contact with the bottom plate. The perforated pipes are connected to the water distribution pipes, and the number of perforated pipes is the same as the number of serrated scrapers. The perforated pipes are located above the serrated scrapers.

[0008] Furthermore, each of the perforated pipes has several circular holes, the diameter of which gradually increases from the side of the perforated pipe closer to the distribution pipe to the side farther away from the distribution pipe. When the jacketed sleeve and the distribution pipe are rotating, the serrated scraper and the perforated pipe are also rotated. Since the pressure is higher near the distribution pipe, the pressure decreases as the water is discharged from the end away from the distribution pipe. Therefore, the circular holes on the distribution pipe are gradually enlarged, so that the water output of each circular hole on the perforated pipe is approximately the same. Moreover, since the perforated pipe is rotating, the water distribution area is larger and the diffusion is more uniform compared to a fixed outlet pipe, which improves the reaction rate of the sewage. The serrated scraper rotates along the bottom plate, scraping and concentrating the sludge settled on the bottom plate, laying the groundwork for centralized sludge treatment.

[0009] Furthermore, a motor and a worm gear are provided on the frame plate. The worm gear is rotatably connected to the frame plate via a bracket. The worm gear is coaxially connected to the motor shaft of the motor. A worm wheel is provided on the interlayer sleeve, and the worm wheel meshes with the worm gear.

[0010] Furthermore, a rotating shaft is provided at the top of the water distribution pipe. The rotating shaft passes through the packing plate and the three-phase separator. Two flat scraper blades are provided on the rotating shaft. The two flat scraper blades contact the upper surface of the packing plate and the three-phase separator, respectively. The water distribution pipe drives the rotating shaft to rotate, and the rotating shaft drives the two flat scraper blades to rotate. The flat scraper blades scrape the sludge settled at the top of the packing plate and the three-phase separator downwards, so that the sludge settles on the bottom plate for centralized treatment.

[0011] Furthermore, each of the sawtooth scrapers has an inner groove that connects to the interlayer sleeve, and each sawtooth scraper has an outer circular hole on both sides that connects to the inner groove. A tube core is slidably installed in the inner groove. The tube core seals the outer circular hole and has an inner circular hole that connects to the outer circular hole. The side of the tube core near the end of the sawtooth scraper is closed, and a hemispherical head is provided at the closed end of the tube core. A ball head spring is provided between the hemispherical head and the sawtooth scraper. A bottom groove that connects to the inner groove is provided at the bottom of the sawtooth scraper corresponding to the position of the hemispherical head. A balance fine hole that connects to the inner groove is provided at the position of the ball head spring on the sawtooth scraper. After scraping and collecting for a period of time, the sawtooth scraper concentrates the sludge between the teeth. The motor stops the sawtooth scraper between a pair of isolation blocks. The control system uses an electromagnet to energize a magnetic suction plate to attract to the bottom plate. The magnetic suction plate moves the isolation blocks upward, so that several sealed triangular spaces are formed between the isolation blocks and the teeth on both sides of the sawtooth scraper.

[0012] Furthermore, the integrated water inlet cleaning assembly also includes a magnetic suction plate and several pairs of isolation blocks. The number of pairs of isolation blocks is the same as the number of serrated scrapers. The isolation blocks are slidably and sealed to the base plate. The magnetic suction plate is positioned between the base plate and the frame plate, and an electromagnet is installed inside the magnetic suction plate. A suction spring is installed between the magnetic suction plate and the base plate. All the isolation blocks are connected to the magnetic suction plate. Each isolation block is hollow, and a through hole is opened on the side of each pair of isolation blocks that are close to each other. A one-way water-blocking skin is installed inside each through hole. The number of through holes is the same as the number of outer circular holes. A water inlet hole is opened at the bottom of each pair of isolation blocks, and each water inlet hole is connected to a clean water pipe. The clean water pipe passes through the magnetic suction plate and the machine housing and communicates with the clean water tank. When the isolation blocks enter the reaction tank... Due to the one-way water-blocking effect of the one-way water-passing skin, the sewage in the reaction tank cannot enter the isolation block. As the magnetic suction plate rises, it squeezes the inclined push block upward. The inclined push block moves upward and pushes the hemispherical head to move. Since there is sludge in the area where the inclined push block is located, the sludge is squeezed out through the balance fine hole. The inclined push block drives the tube core to move, and the inner and outer circular holes are connected. At this time, the suction pump starts, the internal pressure of the tube core decreases, and the pressure in the sealed triangular space decreases further. The one-way water-blocking skin opens, and clean water is sucked into the sealed triangular space. The clean water washes and dilutes the settled sludge, allowing the sludge to enter the inner chute and then into the jacket sleeve. Subsequently, it is extracted by the suction pump, thus cleaning the sludge between the teeth of the saw blade.

[0013] Furthermore, a slanted push block is slidably and sealed at the position of the bottom plate corresponding to the bottom groove. A push block spring is connected between the bottom of the slanted push block and the bottom plate. The magnetic suction plate pushes the slanted push block to move, and the slanted push block pushes the hemispherical head to move. After cleaning is completed, the suction pump stops moving, the electromagnet is de-energized, the magnetic suction plate is reset under the action of the suction plate spring, the slanted push block is reset under the action of the push block spring, the tube core is reset under the action of the ball head spring, and the serrated scraper performs the next round of scraping and cleaning. By setting up the integrated water inlet cleaning component, not only is the water discharge distribution coverage area of ​​the sewage increased, making the sewage diffusion more uniform and achieving the effect of improving the sewage reaction rate, but also the timed cleaning of the settled sludge is achieved, thus preventing sludge sedimentation and accumulation.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] By setting up an integrated water inlet and cleaning component, not only is the coverage area of ​​the wastewater discharge increased, making the wastewater diffusion more uniform and improving the reaction rate of the wastewater; at the same time, the serrated scraper is used to collect the settled sludge, and the isolation block and the serrated scraper work together to form a sealed triangular sludge cleaning space, realizing the timed cleaning of settled sludge and preventing sludge sedimentation and accumulation.

[0026] 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.

[0027] Example: Figures 1-9As shown, the present invention provides a technical solution: an anaerobic reactor with anti-deposition function, comprising a reaction tank 1, an overflow trough 2, a packing plate 5, a three-phase separator 6, a bottom plate 9, a nacelle shell 10, and a frame plate 11. The bottom plate 9 is located at the bottom of the reaction tank 1, the overflow trough 2 is located at the top of the reaction tank 1, a drain pipe 4 is connected below the overflow trough 2, and an exhaust pipe 3 is connected above the overflow trough 2. The packing plate 5 and the three-phase separator 6 are arranged from bottom to top inside the reaction tank 1. The frame plate 11 is integrally formed with the bottom plate 9. The nacelle shell 10 is located below the bottom plate 9. A water inlet cleaning integrated assembly is installed on the bottom plate 9. A sewage inlet pipe 19 and a water pumping pipe 20 are connected below the water inlet cleaning integrated assembly. The sewage inlet pipe 19 and the water pumping pipe 20 penetrate the nacelle shell 10. One end of the water pumping pipe 20 is connected to... A suction pump is connected to the sewage inlet pipe 19, one end of which is connected to the sewage tank. A motor 12 and a worm gear 13 are installed on the frame plate 11. The worm gear 13 is rotatably connected to the frame plate 11 through a bracket. The worm gear 13 is coaxially connected to the motor shaft of the motor 12. A worm wheel 14 is installed on the jacket sleeve 15, and the worm wheel 14 meshes with the worm gear 13. A water pump is connected to the sewage inlet pipe 19 to pump the sewage in the sewage tank into the inner adapter 18. The sewage then enters the water distribution pipe 16 and flows into the reaction tank 1 from the drain pipe 31 on the water distribution pipe 16. After passing through the packing plate 5, the sewage reacts and decomposes. After being separated and blocked by the three-phase separator 6, the treated water and gas rise, the sludge settles, and the treated water and gas enter the overflow tank 2. The treated water is discharged from the drain pipe 4, and the gas is discharged from the exhaust pipe 3.

[0028] The integrated water inlet cleaning unit includes a jacketed sleeve 15, a water distribution pipe 16, an outer adapter 17, and an inner adapter 18. The jacketed sleeve 15 penetrates the base plate 9 and the frame plate 11, and is rotatably and sealingly connected to the base plate 9. The water distribution pipe 16 is installed inside the jacketed sleeve 15, and its bottom is rotatably and sealingly connected to the outer adapter 17. The bottom of the water distribution pipe 16 is rotatably and sealingly connected to the inner adapter 18, which is located below the outer adapter 17. The sewage inlet pipe 19 is connected to the interior of the inner adapter 18, and the pumping pipe 20 is connected to the interior of the outer adapter 17. During the sewage treatment process, the motor 12 drives the worm gear 13 to rotate, and the worm gear 13 drives the worm wheel 14 to rotate. The motor 12 can change the rotation direction of the worm wheel 14 by changing the rotation direction. The worm wheel 14 drives the interlayer sleeve 15 and the water distribution pipe 16 to rotate. Since the outer adapter 17 is rotatably and sealedly connected to the interlayer sleeve 15, and the water distribution pipe 16 is also rotatably and sealedly connected to the inner adapter 18, even if the interlayer sleeve 15 and the water distribution pipe 16 are in a rotating state, the inner adapter 18 can still input sewage into the water distribution pipe 16, and the pumping pipe 20 can also suck sludge from the interlayer sleeve 15.

[0029] The integrated water inlet cleaning component includes several serrated scraper blades 23 and several perforated pipes 31. The serrated scraper blades 23 are arranged in a ring on the interlayer sleeve 15 and are evenly distributed. The serrated scraper blades 23 are in contact with the base plate 9. The perforated pipes 31 are connected to the water distribution pipe 16. The number of perforated pipes 31 is the same as the number of serrated scraper blades 23. The perforated pipes 31 are located above the serrated scraper blades 23. Each perforated pipe 31 has several round holes. The diameter of the round holes gradually increases from the side of the perforated pipe 31 closer to the water distribution pipe 16 to the side of the perforated pipe 31 farther away from the water distribution pipe 16. While rotating, the serrated scraper 23 and the drain pipe 31 are also driven to rotate. Due to the higher pressure near the distribution pipe 16, the pressure decreases at the end away from the distribution pipe 16 as the water pressure decreases. Therefore, the round holes on the distribution pipe 16 are gradually enlarged, making the water output of each round hole on the drain pipe 31 approximately the same. Moreover, since the drain pipe 31 is rotating, the water distribution area is larger and the diffusion is more uniform compared to the fixed outlet pipe, which improves the reaction rate of the sewage. The serrated scraper 23 rotates along the bottom plate 9, scraping and concentrating the sludge that has settled on the bottom plate 9, laying the groundwork for the centralized treatment of the sludge.

[0030] A rotating shaft 7 is installed at the top of the water distribution pipe 16. The rotating shaft 7 passes through the packing plate 5 and the three-phase separator 6. Two flat scraper blades 8 are installed on the rotating shaft 7. The two flat scraper blades 8 contact the upper surface of the packing plate 5 and the three-phase separator 6 respectively. The water distribution pipe 16 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the two flat scraper blades 8 to rotate. The flat scraper blades 8 scrape the sludge settled at the top of the packing plate 5 and the three-phase separator 6 downwards, so that the sludge settles on the bottom plate 9 for centralized treatment.

[0031] Each serrated scraper 23 has an inner groove connecting to the interlayer sleeve 15. Each serrated scraper 23 has outer circular holes on both sides connecting to the inner groove. A core tube 24 is slidably installed in the inner groove, sealing the outer circular holes. The core tube 24 has an inner circular hole connecting to the outer circular holes. The side of the core tube 24 near the end of the serrated scraper 23 is closed. A hemispherical head 25 is provided at the closed end of the core tube 24. A ball-head spring 26 is provided between the hemispherical head 25 and the serrated scraper 23. A bottom groove connecting to the inner groove is provided at the bottom of the serrated scraper 23 corresponding to the position of the hemispherical head 25. A balance hole connecting to the inner groove is provided at the position of the ball-head spring 26 near the serrated scraper 23. The integrated water inlet cleaning assembly also includes a magnetic suction plate 21 and several pairs of isolation blocks 29. The number of isolation blocks 29 is the same as the number of serrated scrapers 23. The isolation blocks 29 are slidably sealed to the base plate 9. The magnetic suction plate 21 is set between the base plate 9 and the frame plate 11. An electromagnet is set inside the magnetic suction plate 21. A suction plate spring 22 is set between the magnetic suction plate 21 and the base plate 9. All isolation blocks 29 are connected to the magnetic suction plate 21. Each isolation block 29 is hollow. A through hole is opened on the side of each pair of isolation blocks 29 that is close to each other. A one-way water baffle (not shown in the figure) is set inside each through hole. The number of through holes is the same as the number of outer circular holes. A water inlet hole 30 is opened at the bottom of each pair of isolation blocks 29. Each water inlet hole 30 is connected to a clean water pipe (not shown in the figure). The clean water pipe passes through the magnetic suction plate 21 and the cabin shell 10 and is connected to the clean water pool.

[0032] After a period of scraping and collecting, the serrated scraper 23 concentrates the sludge between the teeth. The motor 12 rotates the serrated scraper 23 to stop between a pair of isolation blocks 29. The control system energizes the electromagnet to cause the magnetic suction plate 21 to attract to the base plate 9. The magnetic suction plate 21 moves the isolation blocks 29 upward, forming several sealed triangular spaces between the isolation blocks 29 and the teeth on both sides of the serrated scraper 23. When the isolation blocks 29 enter the reaction tank 1, due to the one-way water-blocking effect, the sewage in the reaction tank 1 cannot enter the isolation blocks 29. As the magnetic suction plate 21 rises, it squeezes the inclined push block 27 to move upward. 27 moves upward and pushes the hemispherical head 25 to move. Since there is sludge in the area where the inclined push block 27 is located, the sludge is squeezed out through the balance fine hole. The inclined push block 27 drives the tube core 24 to move. The inner circle hole and the outer circle hole are connected. At this time, the suction pump starts, the internal pressure of the tube core 24 decreases, which further reduces the pressure of the sealed triangular space. The one-way water baffle opens, and clean water is sucked into the sealed triangular space. The clean water washes and dilutes the settled sludge, so that the sludge enters the inner chute and then enters the jacket sleeve 15. Subsequently, it is extracted by the suction pump, thus cleaning the sludge between the teeth of the sawtooth scraper 23.

[0033] A slanted push block 27 is slidably installed at the position of the bottom plate 9 corresponding to the bottom groove. A push block spring 28 is connected between the bottom of the slanted push block 27 and the bottom plate 9. The magnetic suction plate 21 pushes the slanted push block 27 to move, and the slanted push block 27 pushes the hemispherical head 25 to move. After cleaning, the suction pump stops moving, the electromagnet is de-energized, the magnetic suction plate 21 is reset under the action of the suction plate spring 22, the slanted push block 27 is reset under the action of the push block spring 28, the tube core 24 is reset under the action of the ball head spring 26, and the serrated scraper 23 performs the next round of scraping and cleaning. By setting up the integrated water inlet cleaning component, not only is the water discharge distribution coverage area of ​​the sewage increased, making the sewage diffusion more uniform and achieving the effect of improving the sewage reaction rate, but also the timed cleaning of the settled sludge is achieved, thus preventing sludge sedimentation and accumulation.

[0034] The working principle of this invention is as follows: A water pump is connected to the sewage inlet pipe 19 to pump the sewage in the sewage tank into the inner adapter 18. The sewage then enters the water distribution pipe 16 and flows into the reaction tank 1 from the drain pipe 31 on the water distribution pipe 16. After passing through the packing plate 5, the sewage reacts and decomposes. After being separated and blocked by the three-phase separator 6, the treated water and gas rise, the sludge settles, and the treated water and gas enter the overflow tank 2. The treated water is discharged from the drain pipe 4, and the gas is discharged from the exhaust pipe 3.

[0035] During the sewage treatment process, the motor 12 drives the worm gear 13 to rotate, and the worm gear 13 drives the worm wheel 14 to rotate. Changing the rotation direction of the motor 12 can change the rotation direction of the worm wheel 14. The worm wheel 14 drives the interlayer sleeve 15 and the water distribution pipe 16 to rotate. Since the outer adapter 17 is rotatably and sealedly connected to the interlayer sleeve 15, and the water distribution pipe 16 is also rotatably and sealedly connected to the inner adapter 18, even if the interlayer sleeve 15 and the water distribution pipe 16 are in a rotating state, the inner adapter 18 can still input sewage into the water distribution pipe 16, and the pumping pipe 20 can also pump sludge from the interlayer sleeve 15.

[0036] With the jacket sleeve 15 and the water distribution pipe 16 rotating, the serrated scraper 23 and the drain pipe 31 are also driven to rotate. Since the pressure is greater near the water distribution pipe 16, the pressure decreases as the water discharge pressure decreases on the end away from the water distribution pipe 16. Therefore, the round holes on the water distribution pipe 16 are gradually enlarged, so that the water discharge volume of each round hole on the drain pipe 31 is approximately the same. Moreover, the drain pipe 31 is rotating, and compared with the fixed water discharge pipe, the water discharge distribution area is larger and the diffusion is more uniform, which improves the reaction rate of sewage. The serrated scraper 23 rotates along the bottom plate 9, scraping and concentrating the sludge that has settled on the bottom plate 9, laying the groundwork for the centralized treatment of sludge.

[0037] The water distribution pipe 16 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the two flat scraper blades 8 to rotate. The flat scraper blades 8 scrape the sludge settled on the top of the packing plate 5 and the three-phase separator 6 downwards, so that the sludge settles on the bottom plate 9 for centralized treatment.

[0038] After a period of scraping and collecting, the serrated scraper 23 concentrates the sludge between the teeth. The motor 12 rotates the serrated scraper 23 to stop between a pair of isolation blocks 29. The control system energizes the electromagnet to cause the magnetic suction plate 21 to attract to the base plate 9. The magnetic suction plate 21 moves the isolation blocks 29 upward, forming several sealed triangular spaces between the isolation blocks 29 and the teeth on both sides of the serrated scraper 23. When the isolation blocks 29 enter the reaction tank 1, due to the one-way water-blocking effect, the sewage in the reaction tank 1 cannot enter the isolation blocks 29. As the magnetic suction plate 21 rises, it squeezes the inclined push block 27 to move upward. 27 moves upward and pushes the hemispherical head 25 to move. Since there is sludge in the area where the inclined push block 27 is located, the sludge is squeezed out through the balance fine hole. The inclined push block 27 drives the tube core 24 to move. The inner circle hole and the outer circle hole are connected. At this time, the suction pump starts, the internal pressure of the tube core 24 decreases, which further reduces the pressure of the sealed triangular space. The one-way water baffle opens, and clean water is sucked into the sealed triangular space. The clean water washes and dilutes the settled sludge, so that the sludge enters the inner chute and then enters the jacket sleeve 15. Subsequently, it is extracted by the suction pump, thus cleaning the sludge between the teeth of the sawtooth scraper 23.

[0039] After cleaning is completed, the suction pump stops moving, the electromagnet is de-energized, the magnetic suction plate 21 is reset under the action of the suction plate spring 22, the inclined push block 27 is reset under the action of the push block spring 28, the tube core 24 is reset under the action of the ball head spring 26, and the serrated scraper 23 performs the next round of scraping and cleaning. By setting up the integrated water inlet cleaning component, not only is the water discharge distribution coverage area of ​​the sewage increased, making the sewage diffusion more uniform and achieving the effect of improving the sewage reaction rate, but also the timed cleaning of the settled sludge is achieved, thus preventing sludge sedimentation and accumulation.
