Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically a multi-stage reaction-separation combined wastewater treatment device. Background Technology

[0002] With the rapid development of industry and increasingly stringent environmental standards, wastewater treatment has become a key link in ensuring the sustainable development of the ecological environment. Wastewater often contains a variety of pollutants, among which gases such as carbon dioxide and various impurities have a significant impact on water quality. Direct discharge can cause serious damage to aquatic ecosystems, leading to problems such as water acidification and reduced dissolved oxygen, threatening the survival of aquatic organisms and affecting the recycling of water resources.

[0003] Currently, there are various wastewater treatment devices on the market. In terms of gas-liquid separation, some devices use the simple principle of gravity sedimentation, relying on the density difference between gas and liquid to allow the gas to separate naturally from the liquid. Others use cyclone separation technology, which uses the high-speed rotation of the gas-liquid mixture to generate centrifugal force to achieve gas-liquid separation. In the decarbonization process, it is common to use packed towers for gas-liquid mass transfer decarbonization, which increases the gas-liquid contact area by using packing to promote the transfer of carbon dioxide from the liquid phase to the gas phase.

[0004] However, traditional gravity settling gas-liquid separators have limited ability to separate microbubbles and droplets. When treating wastewater containing surfactants or other substances that alter the gas-liquid interface, the gas-liquid separation efficiency drops significantly. In actual wastewater treatment, the wastewater flow rate and water quality are unstable, and existing gas-liquid separators cannot guarantee efficient separation under various operating conditions. This leads to gaseous impurities interfering with the decarbonization and other treatment effects in subsequent processes.

[0005] In conventional packed tower decarbonization, there is a problem of uneven gas-liquid distribution, which prevents some packing from fully functioning and reduces mass transfer efficiency. At the same time, the packing is easily contaminated and clogged by suspended solids, organic matter and salts in the wastewater, which not only increases equipment maintenance costs but also greatly reduces the decarbonization effect. Existing gas-liquid separation equipment and decarbonization equipment are often independent of each other and operate independently, which makes the entire wastewater treatment process cumbersome and complicated and requires a lot of space to accommodate each piece of equipment. Summary of the Invention

[0006] To overcome the above-mentioned defects, the present invention provides a multi-stage reaction-separation combined wastewater treatment device, which solves the problem that in existing wastewater treatment gas-liquid separators, the baffles at the liquid inlet are mostly fixed and difficult to adjust according to the real-time conditions of the wastewater. When the wastewater flow or composition changes greatly, the separation effect will be affected. At the same time, the packing is easily contaminated and clogged by suspended solids, organic matter and salts in the wastewater, which affects the decarbonization effect.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multi-stage reaction-separation combined wastewater treatment device, comprising a separation tower body and a decarbonization tower body.

The discharge port of the conveying pipe is connected to the main body of the decarbonization tower. A second inlet pipe for use with the conveying pipe is provided on the outside of the main body of the decarbonization tower.

[0008] As a further embodiment of the present invention: the second inlet pipe is located above the main body of the decarbonization tower. A spray mechanism for use with the second inlet pipe is snapped and installed inside the main body of the decarbonization tower. A first limiting ring and a second limiting ring are fixedly installed in a symmetrical structure inside the main body of the decarbonization tower. A packing block is slidably connected inside both the first limiting ring and the second limiting ring. The packing block is filled with packing material. A bidirectional threaded rod is rotatably connected inside the main body of the decarbonization tower. The bidirectional threaded rod is threaded through the packing block. A locking block is fixedly connected to the bidirectional threaded rod at the middle position. An air blowing mechanism is snapped and connected inside the locking block. The bottom of the bidirectional threaded rod passes through the bottom of the main body of the decarbonization tower. A transmission gear is fixedly connected to the outer side of the bottom of the bidirectional threaded rod. A drive gear is meshed with one side of the transmission gear. A first motor is fixedly connected to the bottom of the drive gear. A gas collecting block is fixedly installed inside the main body of the decarbonization tower below the second limiting ring. A first air inlet pipe is connected to one side of the gas collecting block. The other end of the first air inlet pipe passes through the main body of the decarbonization tower.

[0009] As a further aspect of the present invention: the air blowing mechanism includes an air conveying rod, which is fixed to the outside of the bidirectional threaded rod by the clamping block, and the upper and lower ends of the air conveying rod are symmetrically connected to an exhaust ring. The exhaust ring is provided with multiple sets of air nozzles that cooperate with the packing block. The exhaust ring has a spiral structure. A connecting pipe is connected to the inside of the air conveying rod. The connecting pipe is located inside the bidirectional threaded rod.

[0011] As a further embodiment of the present invention: a first exhaust pipe is provided at the top of the separation tower body, a second exhaust pipe is provided at the top bottom of the decarbonization tower body, and support brackets are provided on the outer sides of the bottom of both the separation tower body and the decarbonization tower body.

[0012] As a further aspect of the present invention: a protective box is bolted to the top of the decarbonization tower body, and the first motor is located inside the protective box.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By combining the preliminary gas-liquid separation function of the separation tower body with the deep decarbonization function of the decarbonization tower body, the gas-liquid separation effect can be flexibly adjusted according to the actual wastewater conditions through the synergistic effect of the multi-angle adjustable baffle mechanism and the fixed baffle in the separation tower. This effectively removes some gases and impurities. After entering the decarbonization tower, the spray mechanism evenly disperses the wastewater, increasing the gas-liquid contact area. The movable structure of the packing block and the rotation of the air blowing mechanism further enhance the gas-liquid mass transfer process, enabling gases such as carbon dioxide to be separated from the wastewater more efficiently, greatly improving the overall wastewater treatment effect. 2. The multi-angle adjustable baffle mechanism can adjust the angle of the movable baffle in real time according to the different properties of wastewater such as flow rate, velocity, viscosity, and gas content. This creates a flow state more conducive to gas-liquid separation within the separation tower. In the decarbonization tower, the movement of the packing blocks can also be controlled by adjusting the first motor to adapt to the decarbonization requirements of different water qualities, ensuring that the equipment achieves good treatment results when dealing with various complex wastewaters.

Detailed Implementation

[0016] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0017] like Figures 1-7 As shown, the present invention provides a technical solution: A multi-stage reaction-separation combined wastewater treatment device includes a separation tower body 1 and a decarbonization tower body 2. A first inlet pipe 102 is connected to the outside of the separation tower body 1. A multi-angle adjustable baffle mechanism 4 and a fixed baffle 6 are installed inside the separation tower body 1 below the inlet of the first inlet pipe 102. The multi-angle adjustable baffle mechanism 4 includes a fixed ring 401, located below the inlet of the first inlet pipe 102 and fixedly connected to the inner wall of the separation tower body 1. A rotating ring 402 is rotatably connected to the inner side of the fixed ring 401. Multiple sets of connecting rods 404 are rotatably connected inside the rotating ring 402. Movable baffles 403 are fixedly connected to the inner side of each connecting rod 404. The other end of each connecting rod 404 movably passes through the rotating ring 402. A driving ring 405 is provided on the outside of the rotating ring 402. Multiple sets of protrusions 406 are fixedly connected inside the driving ring 405. The protrusions 406 are located inside the connecting rods 404. The outer end of the connecting rods 404 has a long rectangular structure and is open at the outer end. A sliding groove is provided for use with the protrusion 406. Multiple sets of connecting rods 408 are fixedly connected to the bottom of the drive ring 405. A connecting block 407 is fixedly connected to the other end of the connecting rod 408. The connecting block 407 is located at the center of the movable baffle 403. The end of the movable baffle 403 away from the connecting rod 404 is rotatably connected to the outside of the connecting block 407. A protective block 22 is fixedly connected to the separation tower body 1. The protective block 22 penetrates the separation tower body 1. A second motor 18 is installed on the outside of the separation tower body 1. The second motor 18 is fixed to the top of the protective block 22. A transmission mechanism 19 for use with the connecting block 407 is provided inside the protective block 22. The transmission mechanism 19 includes a transmission wheel and a transmission belt. A first drain pipe 103 is opened at the bottom of the separation tower body 1. A conveying pipe 10 is connected inside the first drain pipe 103. The discharge port of the conveying pipe 10 is connected to the decarbonization tower body 2. A second inlet pipe 202 for use with the conveying pipe 10 is provided on the outside of the decarbonization tower body 2. Specifically, wastewater enters the separation tower body 1 through the first inlet pipe 102. The second motor 18 is started, driving the connecting block 407 via the transmission mechanism 19. The connecting block 407 drives the drive ring 405 to rotate via the connecting rod 408. The protrusion 406 inside the drive ring 405 slides within the groove of the connecting rod 404, thereby causing the connecting rod 404 to drive the movable baffle 403 to rotate, achieving multi-angle adjustment. This allows the angle of the movable baffle 403 to be adjusted according to factors such as the wastewater's flow rate, velocity, and properties, thereby changing the wastewater's flow direction and flow state. Through multi-angle adjustment... After adjustment by the baffle mechanism 4, the wastewater continues to flow downwards and encounters the fixed baffle 6. The fixed baffle 6 further changes the flow direction of the wastewater, promoting the initial separation of gas and liquid. The separated liquid is discharged through the first drain pipe 103 and then transported to the decarbonization tower body 2 through the conveying pipe 10. The wastewater enters the decarbonization tower body 2 through the conveying pipe 10 and the second inlet pipe 202. Decarbonization treatment is carried out in the decarbonization tower body 2. The decarbonization tower body 2 usually has packing and other structures to promote gas-liquid mass transfer, so that the carbon dioxide and other gases in the wastewater are transferred from the liquid phase to the gas phase, thereby achieving decarbonization. The multi-angle adjustable baffle mechanism 4 can adjust the angle of the movable baffle 403 according to different working conditions, so that the wastewater forms a flow state more conducive to gas-liquid separation in the main body of the separation tower 1. For example, when the wastewater flow rate is large, the tilt angle of the movable baffle 403 can be increased to increase the residence time and disturbance of the wastewater and improve the gas-liquid separation efficiency. Different wastewaters may have different properties, such as viscosity and gas content. The multi-angle adjustable baffle mechanism 4 can adjust the baffle angle according to the specific properties of the wastewater to adapt to the separation requirements of different water qualities, improve the versatility and adaptability of the equipment. The second motor 18 and the transmission mechanism 19 can realize flexible control of the angle of the movable baffle 403, which is convenient for operators to make real-time adjustments according to the actual situation and ensure the stability of the separation effect. The second inlet pipe 202 is located above the decarbonization tower body 2. A spray mechanism 7, used in conjunction with the second inlet pipe 202, is snap-fitted into the upper part of the decarbonization tower body 2. A first limiting ring 8 and a second limiting ring 9 are symmetrically fixedly installed inside the decarbonization tower body 2. Packing blocks 20 are slidably connected to both the first limiting ring 8 and the second limiting ring 9, and the packing blocks 20 are filled with packing material. A bidirectional threaded rod 16 is rotatably connected inside the decarbonization tower body 2, with its threads penetrating the packing blocks 20. The bidirectional threaded rod 16 is fixed in the middle position. A locking block 21 is connected, and an air blowing mechanism 3 is snapped into the locking block 21. The bottom of the bidirectional threaded rod 16 penetrates the bottom of the decarbonization tower body 2, and a transmission gear 13 is fixedly connected to the outer side of the bottom of the bidirectional threaded rod 16. A drive gear 12 is meshed with one side of the transmission gear 13. A first motor 11 is fixedly connected to the bottom of the drive gear 12. A gas collecting block 15 is fixedly installed inside the decarbonization tower body 2 below the second limiting ring 9. A first air inlet pipe 5 is connected to one side of the gas collecting block 15, and the other end of the first air inlet pipe 5 penetrates the decarbonization tower body 2. Specifically, wastewater enters the decarbonization tower body 2 through the second inlet pipe 202. Then, a spray mechanism 7, which works in conjunction with the second inlet pipe 202, evenly sprays the wastewater into the decarbonization tower body 2. This increases the contact area between the wastewater and subsequent components, preparing for the decarbonization process. The first motor 11 is started, driving the drive gear 12 to rotate. The drive gear 12 meshes with the transmission gear 13, causing the transmission gear 13 to drive the bidirectional threaded rod 16 to rotate. Since the threads of the bidirectional threaded rod 16 penetrate the packing block 20, and the packing block 20 slides within the first limiting ring 8 and the second limiting ring 9, the rotation of the bidirectional threaded rod 16 drives the two packing blocks 20 along... The first limiting ring 8 and the second limiting ring 9 move in opposite directions or in a straight line. During the rotation of the bidirectional threaded rod 16, the air blowing mechanism 3, which is connected to the locking block 21 located in the middle position of the bidirectional threaded rod 16, will also rotate. When the air blowing mechanism 3 rotates, it will blow air to the surroundings to accelerate the gas-liquid mixing and mass transfer process. The gas generated during the decarbonization process flows downward and collects in the gas collecting block 15 located below the second limiting ring 9. At the same time, external air or other gases used to assist decarbonization enter the gas collecting block 15 through the first air inlet pipe 5, and then flow upward in the decarbonization tower body 2, making full contact with the wastewater and promoting the separation of gases such as carbon dioxide from the wastewater. The spray mechanism 7 can uniformly disperse wastewater into small droplets, greatly increasing the contact area between wastewater and packing material and gas, making the gas-liquid mass transfer process more complete, thereby improving decarbonization efficiency. The packing block 20 can move under the drive of the bidirectional threaded rod 16, changing the distribution state of the packing material in the decarbonization tower, allowing wastewater to contact the packing material at different positions, increasing the contact opportunities and time between wastewater and packing material, further strengthening the gas-liquid mass transfer process, and improving the decarbonization effect. The packing material can be controlled according to the actual situation such as wastewater flow rate and water quality by adjusting the rotation direction and speed of the first motor 11. The moving distance and speed of the material block 20 enable the decarbonization tower to better adapt to different working conditions, improve the versatility and flexibility of the equipment, and the rotation of the blowing mechanism 3 can accelerate the flow of gas in the decarbonization tower, so that the gas and wastewater are mixed more fully, accelerate the escape of gases such as carbon dioxide from the wastewater, and improve the decarbonization efficiency. The gas collecting block 15 can effectively collect the gas generated during the decarbonization process for subsequent treatment. At the same time, the first air inlet pipe 5 introduces external gas, which can provide sufficient gas-liquid mass transfer driving force to maintain the stability of the decarbonization process and ensure the decarbonization effect. The blowing mechanism 3 includes an air delivery rod 301, which is fixed to the outside of the bidirectional threaded rod 16 by a locking block 21. The upper and lower ends of the air delivery rod 301 are symmetrically connected to an exhaust ring 303. The exhaust ring 303 is provided with multiple sets of air nozzles that cooperate with the packing block 20. The exhaust ring 303 has a spiral structure. The inner side of the air delivery rod 301 is connected to a connecting pipe 302. The connecting pipe 302 is located inside the bidirectional threaded rod 16. The bidirectional threaded rod 16 has an installation groove that cooperates with the connecting pipe 302 and the air delivery rod 301. The bottom end of the connecting pipe 302 penetrates the bottom of the decarbonization tower body 2, and the bottom of the connecting pipe 302 is rotatably connected to a second air inlet pipe 14. Specifically, the spiral shape increases the coverage area of ​​the exhaust ring 303 within the decarbonization tower, while multiple sets of nozzles allow the gas to be ejected from multiple directions and angles. When the gas exits from the nozzles, it can more widely and evenly contact the packing material in the packing block 20 and the wastewater flowing through it, greatly increasing the gas-liquid contact area and contact opportunities. This effectively improves the gas-liquid mass transfer efficiency and promotes the removal of gases such as carbon dioxide from the wastewater. Since the nozzles are used in conjunction with the packing block 20, this means the gas can directly act on the wastewater liquid film on the packing surface, accelerating the gas transfer process from the liquid phase to the gas phase. When in use, the wastewater forms a thin liquid film, and the gas sprayed from the nozzle can break the balance on the surface of the liquid film in time, making it easier for gases such as carbon dioxide to escape and improving the decarbonization effect. The bottom of the connecting pipe 302 is rotatably connected to the second air inlet pipe 14. Since the bidirectional threaded rod 16 will rotate and drive the air delivery rod 301 and the exhaust ring 303 to rotate together, this rotatable connection design can ensure that during the rotation of the blowing mechanism 3, the gas can still be smoothly delivered to the air delivery rod 301 and the exhaust ring 303 through the second air inlet pipe 14 and the connecting pipe 302, without the pipe twisting or the gas delivery being blocked due to the rotation. The packing block 20 has a symmetrical structure with limit blocks installed on its outer side. The first limit ring 8 and the second limit ring 9 have limit grooves that cooperate with the limit blocks. The top of the separation tower body 1 has a first exhaust pipe 101. The bottom top of the decarbonization tower body 2 has a second exhaust pipe 201. The bottom outer sides of both the separation tower body 1 and the decarbonization tower body 2 are equipped with support brackets. The top of the decarbonization tower body 2 is bolted with a protective box 17. The first motor 11 is located inside the protective box 17. Specifically, the limiting block on the outside of the packing block 20 cooperates with the limiting groove in the first limiting ring 8 and the second limiting ring 9 to ensure that the packing block 20 moves along a specific trajectory and slides stably within the first limiting ring 8 and the second limiting ring 9. This ensures that the gas-liquid flow between the packing blocks 20 is uniform and stable, thereby ensuring the stability of the gas-liquid mass transfer effect during the decarbonization process. When the separation tower body 1 performs the initial gas-liquid separation, the generated gas density is relatively small and will accumulate upward. The first exhaust pipe 101 is set at the top of the separation tower body 1 to discharge the separated gas in time, avoiding excessive gas accumulation in the tower that would cause pressure to rise and affect the normal operation of the separation tower. After the decarbonization process is completed in the decarbonization tower body 2, the generated carbon dioxide and other gases will also rise to the top of the tower. The setting of the second exhaust pipe 201 can smoothly discharge these removed gases, ensuring the pressure in the decarbonization tower is stable, maintaining the balance of the decarbonization process, and helping to improve the decarbonization efficiency and effect. The working principle of this invention is as follows: First, wastewater enters the separation tower body 1 through the first inlet pipe 102. At this time, the multi-angle adjustable baffle mechanism 4 plays a key role. The second motor 18 drives the connecting block 407 through the transmission mechanism 19, which drives the drive ring 405 and the connecting rod 404 to rotate the movable baffle 403. The angle is flexibly adjusted according to the wastewater flow rate, velocity and properties to change the wastewater flow direction and flow state, and initially separate the gas and liquid. Subsequently, the fixed baffle 6 further changes the wastewater flow direction and enhances the gas-liquid separation effect. The separated liquid enters the decarbonization tower body 2 through the first drain pipe 103 and the conveying pipe 10. Secondly, the wastewater entering the main body 2 of the decarbonization tower is evenly sprayed by the spraying mechanism 7 that cooperates with the second liquid inlet pipe 202, increasing the contact area with subsequent components. The first motor 11 starts and drives the bidirectional threaded rod 16 to rotate through the drive gear 12 and the transmission gear 13, driving the two packing blocks 20 to move towards or away from each other within the first limit ring 8 and the second limit ring 9, changing the packing distribution state, increasing the contact opportunities and time between the wastewater and the packing, and enhancing gas-liquid mass transfer. At the same time, the rotation of the bidirectional threaded rod 16 drives the air blowing mechanism 3 to rotate, and multiple sets of air nozzles on the spiral exhaust ring 303 blow air to the surroundings, accelerating gas-liquid mixing and promoting the escape of gases such as carbon dioxide from the wastewater. It is worth mentioning that the connecting pipe 302 of the blowing mechanism 3 is rotatably connected to the second air inlet pipe 14 to ensure smooth gas delivery when the blowing mechanism 3 rotates; the limiting block on the outside of the packing block 20 cooperates with the limiting groove of the limiting ring to ensure stable movement of the packing block 20 and maintain stable gas-liquid mass transfer effect; the exhaust pipes at the top of the separation tower body 1 and the decarbonization tower body 2 respectively discharge the gas initially separated in the separation tower and the carbon dioxide and other gases removed in the decarbonization tower in a timely manner to ensure stable pressure inside the equipment; the support bracket provides stable support for the equipment, and the protective box 17 protects the first motor 11 from external interference; Finally, the gas generated during the decarbonization process is collected in the gas collection block 15. External air or other auxiliary decarbonization gases enter the gas collection block 15 through the first air inlet pipe 5, flow upward in the decarbonization tower and come into full contact with the wastewater, further promoting the separation of gases such as carbon dioxide, achieving efficient decarbonization, and the treated wastewater meets the discharge standards or enters the subsequent treatment process.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
