Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, specifically to a modular high-salinity wastewater treatment device. Background Technology

[0002] High-salinity wastewater refers to a type of wastewater with a total dissolved solids concentration typically higher than 1% (10,000 mg / L). It mainly originates from specific industrial processes and seawater desalination and is characterized by significant inhibition of biological activity, easy scaling and corrosion, high treatment difficulty and cost, and poses a potential threat to the ecological environment. Therefore, removing organic pollutants from high-salinity wastewater is crucial to mitigating its environmental impact.

[0003] In existing technologies, evaporators are generally used to remove organic pollutants from high-salinity wastewater. Steam is directly discharged into a closed space filled with condenser tubes through steam pipes. The steam liquefies and releases heat when it encounters the cold (condenser tubes), heating the wastewater inside the tubes to evaporate and concentrate it. However, since most existing evaporators adopt a direct-discharge steam supply mode, the steam enters the evaporation chamber through the steam pipes and exhibits a non-uniform diffusion state. This results in uneven distribution of steam in the space, with high steam concentration, high heat, and high liquefaction heat release intensity in the condenser tube area near the steam pipes, while the area far from the steam pipes has thin steam, low heat, and weak liquefaction effect. This significant spatial difference easily forms a temperature gradient, leading to severe uneven heating of the condenser tubes, which reduces the overall thermal conductivity of the evaporator. To reasonably improve this problem, this application proposes a modular high-salinity wastewater treatment device. Summary of the Invention

[0004] To achieve the above objectives, this application specifically adopts the following technical solution: A modular high-salinity wastewater treatment device, comprising: The collection bucket has a discharge port at the bottom and an exhaust port on one side.

An air outlet pipe and a water outlet pipe are provided on the cylindrical box. Multiple heat insulation tubes are fitted inside the top surface of the insulated box, and the bottom ends of the heat insulation tubes are located inside the heat exchange tubes, with a gap between them. The separatory tank is equipped with an inlet pipe. Multiple heat-conducting pipes are distributed inside the separatory tank. The top of the heat-conducting pipes extends towards the top of the separatory tank, and the bottom of the heat-insulating pipe passes through the bottom of the cylindrical box and is connected to the collection tank.

[0005] Furthermore, the opening of the liquid separator is connected to an installation plate, the liquid inlet pipe passes through the installation plate, the installation plate has a liquid separation chamber, and the top of the installation plate is equipped with a liquid extraction component for extracting liquid from the liquid separator into the liquid separation chamber. The bottom of the installation plate has multiple tubes, and the bottom ends of the tubes are inserted into multiple heat-conducting tubes respectively.

[0006] Furthermore, a frame is inserted into the liquid separation chamber, and multiple rods are connected to the frame. The bottom end of each rod penetrates the tube and is connected to a guide block. The top of the guide block is constructed with a guide slope, which extends toward the inner wall of the tube.

[0007] Furthermore, a column is rotatably mounted on the mounting plate, and a motor is mounted on the mounting plate to drive the column to rotate. The bottom end of the column passes through the liquid distribution chamber, and multiple arc-shaped protrusions are spirally distributed on its outer side. Multiple sound plates are distributed in a ring on the frame, and multiple reeds are linearly distributed on the sound plates. The arc-shaped protrusions abut and overlap with the ends of the reeds.

[0008] Furthermore, the rod body is provided with a through hole extending along its axis, and the bottom of the guide block is provided with a sound amplification groove that is connected to the through hole.

[0009] Furthermore, the liquid extraction assembly includes a cylindrical box mounted on a mounting plate. A cylindrical block is eccentrically mounted inside the cylindrical box. The rotating shaft of the cylindrical block passes through the cylindrical box and is connected to the cylinder body via a ratchet and pawl mechanism. Multiple sliding grooves are distributed in a ring on the outer side of the cylindrical block. A sliding plate is slidably fitted inside the sliding groove. The sliding plate is connected to the sliding groove via a compression spring, and its protruding end slidably overlaps with the inner wall of the cylindrical box. A liquid extraction pipe and a liquid outlet pipe are connected to the cylindrical box and pass through the liquid distribution tank and the liquid distribution chamber, respectively.

[0010] Furthermore, the mounting plate is detachably connected to the dispensing tank, and a cover plate is detachably installed on the top of the mounting plate to cover the dispensing chamber. The column, motor and cylindrical box are all mounted on the cover plate. A vertical pipe is constructed at the bottom of the mounting plate, and the liquid extraction pipe is threadedly connected to the top of the vertical pipe. The bottom end of the liquid outlet pipe passes through the cover plate.

[0011] Furthermore, a vapor-liquid separator is installed on the outside of the collection tank, with its input end connected to the exhaust port and the outlet pipe, and the output end of the vapor-liquid separator connected to a steam compressor and a steam pipeline.

[0012] Furthermore, the bottom surface of the cylindrical box is constructed with an annular groove, the outlet pipe is U-shaped and its input end is inserted into the annular groove, a liquid storage tank is fixed on the outside of the collection bucket, the output end of the U-shaped pipe passes through the liquid storage tank, and an outlet is constructed at the top of the liquid storage tank.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0017] like Figures 1-15 As shown, one embodiment of this application discloses a modular high-salinity wastewater treatment device, comprising: The collection bucket 1 has a discharge port 2 at the bottom, the opening of the collection bucket 1 faces upward, and an exhaust port 3 is constructed on one side of the collection bucket 1; A cylindrical box 4 covers the opening of the collection bucket 1. An insulated box 5 is connected to the top of the cylindrical box 4, and a steam pipe 6 is connected to the insulated box 5. Steam enters the insulated box 5 through the steam pipe 6. The inner liner of the insulated box 5 is made of 316L stainless steel and filled with closed-cell polyurethane foam, providing good insulation performance. Multiple heat exchange tubes 7 are vertically distributed at the bottom of the insulated box 5, with their tops connected to the interior of the insulated box 5. All heat exchange tubes 7 penetrate the top surface of the cylindrical box 4. The cylindrical box 4 is equipped with a steam outlet pipe 8 and a water outlet pipe 9, which are used to discharge water from the cylindrical box. The steam inside the cylindrical box 4 and the water condensed after the steam is cooled are connected to the insulated box 5 through heat exchange tubes 7. Multiple heat insulation tubes 10 are installed on the top surface of the insulated box 5. The multiple heat insulation tubes 10 correspond one-to-one with the multiple heat exchange tubes 7. The bottom end of the heat insulation tube 10 is located inside the heat exchange tube 7 and there is a gap between them. The outer diameter of the heat insulation tube 10 is slightly smaller than the inner diameter of the heat exchange tube 7. When the steam rushes into the cylindrical box 4, it will increase the internal pressure of the cylindrical box 4 and squeeze the high temperature steam inside it evenly into the multiple heat exchange tubes 7, thereby achieving uniform distribution. The separating tank 11 is equipped with an inlet pipe 12 for injecting high-salt wastewater into it. Multiple heat-conducting pipes 13 are distributed within the separating tank 11. These heat-conducting pipes 13 are vertically arranged, with their tops extending towards the top of the separating tank 11. The tops of the heat-conducting pipes 13 are below the opening of the separating tank 11. With this design, when the high-salt wastewater overflows the openings of the heat-conducting pipes 13, a "thin stream" phenomenon occurs, where the high-salt wastewater flows downwards along the wall of the heat-conducting pipes 13 under the combined action of pressure difference and gravity. At this time, a uniform liquid film can form on the wall of the heat-conducting pipes 13, with its bottom end penetrating successively through the heat insulation pipe 10 and the bottom surface of the cylindrical box 4, thereby slowing down heat exchange. The flow rate of wastewater in pipe 7 is connected to the collection tank 1. The liquid separator 11, together with the heat-conducting pipe 13, can seal the heat exchange pipe 7. The heat-conducting pipe 13 coaxially passes through the heat exchange pipe 7, and there is a gap between the two. When the steam in the heat preservation box 5 enters the cylindrical box 4 through the heat exchange pipe 7, it will fully contact the outer surface of the heat-conducting pipe 13, so as to fully heat the heat exchange pipe 7, thereby evaporating the water in the liquid film flowing on the inner wall of the heat exchange pipe 7, improving the evaporation efficiency of steam on wastewater, making it evaporate and concentrate, and reducing the water in the high-salt wastewater entering the collection tank 1. After completing the above process, the steam generated by evaporation can be discharged through the exhaust port 3, and the concentrated high-salt wastewater can be discharged from the collection tank 1 through the exhaust port 2. In simple terms, the principle here is that when the high-temperature steam encounters the cooler outer wall of the heat pipe 13, the steam will cool down and liquefy to produce condensate. During the liquefaction process, heat is released. The outer wall of the heat pipe 13 absorbs the heat generated by the liquefaction of the steam and transfers this heat to the liquid film flowing on the inner wall of the heat pipe 13. After absorbing the heat from the heat pipe 13, the temperature of the liquid film rises, causing some of the water in the liquid film to evaporate and form a high-salt wastewater concentrate. In this application, when steam rushes into the cylindrical box 4, it increases the internal pressure of the cylindrical box 4 and evenly squeezes the high-temperature steam inside into multiple heat exchange tubes 7. Compared with the existing structure that uses direct steam supply, this application can achieve uniform distribution of high-temperature steam, so that multiple heat conduction tubes 13 can be heated evenly and multiple heat conduction tubes 13 are less likely to form a temperature gradient, thereby improving the evaporation efficiency of the liquid film flowing on the inner wall of the heat conduction tubes 13.

[0018] like Figure 8 , Figure 9 , Figure 12 and Figure 14As shown, a further technical solution of this application is disclosed. The opening of the separating tank 11 is connected to the mounting plate 14, which covers the opening of the separating tank 11. The inlet pipe 12 passes through the mounting plate 14. The mounting plate 14 has a separating chamber 15. A liquid extraction component 16 is installed on the top of the mounting plate 14 to extract the liquid in the separating tank 11 into the separating chamber 15. Because the opening of the heat-conducting pipe 13 is higher than the bottom surface of the separating tank 11, some high-salt wastewater will remain in the separating tank 11 after the high-salt wastewater is separated. Multiple tubes 17 are distributed at the bottom of the mounting plate 14. Each tube 17 corresponds to a heat-conducting pipe 13, and its bottom end is inserted into multiple heat-conducting pipes 13. The liquid extraction component 16 can extract the high-salt wastewater remaining in the separating tank 11 and distribute it evenly through the separating chamber 15 and multiple tubes 17, so that it can enter the collection tank 1 through multiple heat-conducting pipes 13.

[0019] like Figure 8 and Figure 9 As shown, a further technical solution of this application is disclosed. A frame 18 is inserted into the liquid distribution chamber 15. Multiple rods 19 are connected to the frame 18. Each rod 19 corresponds to a tube 17. The bottom end of the rod 19 penetrates the tube 17. There is a gap between the outer side of the rod 19 and the inner wall of the tube 17, and a guide block 20 is connected thereto. The top of the guide block 20 is constructed with a guide slope 21, and the guide slope 21 extends toward the inner wall of the tube 17. The high-salt wastewater in the liquid distribution chamber 15 can flow down from the gap between the tube 17 and the rod 19. When it falls onto the guide block 20 under the action of gravity, it will pass through the guide slope 21 under the action of inertia and flow toward the inner wall of the heat conduction pipe 13, where the water inside can be evaporated through the heat conduction pipe 13.

[0020] like Figure 5 , Figure 12 and Figure 13 As shown, a further technical solution of this application is disclosed. A column 36 is rotatably mounted on the mounting plate 14. A motor 22 is mounted on the mounting plate 14 to drive the column 36 to rotate. The motor 22 is a hollow shaft reduction motor 22. The column 36 is connected to its hollow shaft. The bottom end of the column 36 passes through the liquid distribution chamber 15, and multiple arc-shaped protrusions 23 are spirally distributed on its outer side. Multiple sound plates 24 are distributed in a ring on the frame 18. Multiple reeds 25 are linearly distributed on the sound plates 24. The arc-shaped protrusions 23 abut and overlap with the ends of the reeds 25. The structure here is similar to a music box. That is, when the motor 22 drives the column 36 to rotate, the multiple reeds 25 on the sound plates 24 are sequentially plucked by the multiple arc-shaped protrusions 23 on the outer surface of the column 36, thereby producing a crisp sound. This application utilizes vibrations generated by mechanical manipulation, i.e., low-frequency sound waves. When these vibrations are coupled to the wall of the heat pipe 13, they propagate primarily as stress waves within the wall of the heat pipe 13. Their propagation efficiency is far higher than that in air. When the wall of the heat pipe 13 vibrates, it couples with the liquid flowing on the inner wall of the heat pipe 13, thereby transferring vibrational energy to the liquid. This disturbance of the fluid inhibits the adhesion of salt crystals to the pipe wall. It should be specifically noted that the reason why the anti-scaling measures in the prior art require a specific frequency "ultrasound > 20kHz" and a sound field with sufficient power is because the amount of wastewater in the treatment container is large, and insufficient power is not enough to affect the wastewater and prevent scale formation on the inner wall of the treatment container. However, in the technical solution of this application, the high-salt wastewater flows downward along the wall of the heat pipe 13 in a "thin stream" shape, which is easily affected. Moreover, the sound waves entering the heat pipe 13 will cause the pipe wall to vibrate. This means that even low-frequency sound waves generated by mechanical manipulation can suppress the adhesion of salt crystals on the pipe wall by causing resonance of the heat pipe 13.

[0021] like Figure 8 and Figure 9 As shown, a further technical solution of this application is disclosed. A through hole 26 extending along its axis is constructed on the rod 19. A sound amplification groove 27 is opened at the bottom of the guide block 20. The inner diameter of the sound amplification groove 27 gradually decreases from bottom to top and is connected to the through hole 26. The sound generated by the reed 25 being plucked can enter the through hole 26 and then be emitted from the bottom of the sound amplification groove 27. The structure here is similar to a paper horn. This design utilizes the design of the rod 19 and the through hole 26 to reduce the diffusion and attenuation of sound waves during propagation and guide its energy more effectively to the heat conduction pipe 13 through the sound amplification groove 27. This makes the sound more concentrated during propagation, thereby enhancing the loudness and influence of the sound and making it less likely for high-salt wastewater to crystallize on the inner wall of the heat conduction pipe 13. In summary, the core function of the amplification slot 27 is not to "amplify" the liquid. Since the high-salt wastewater flows downwards along the wall of the heat pipe 13, combined with... Figure 8 There is a gap between the guide block 20 and the wall of the heat pipe 13, so that the sound waves emitted by the sound amplification slot 27 can be coupled to the wall of the heat pipe 13.

[0022] like Figure 8 , Figure 9 , Figure 12 , Figure 13 and Figure 14The specific structure of the liquid extraction assembly 16 of this application is disclosed. The liquid extraction assembly 16 includes a cylindrical box 1601 mounted on a mounting plate 14. A cylindrical block 1602 is eccentrically mounted inside the cylindrical box 1601. The cylindrical block 1602 rolls against the inner wall of the cylindrical box 1601. The rotating shaft of the cylindrical block 1602 passes through the cylindrical box 1601 and is connected to the column body 36 through a ratchet and pawl mechanism 1603. It includes a ratchet groove 16031 constructed on the rotating shaft of the cylindrical block 1602 and an insert post 16032 constructed on the top of the column 36. The insert post 16032 has a hinge groove 16033 distributed around its periphery. A stop block 16034 is hinged in the hinge groove 16033. A torsion spring 16035 is sleeved on the hinge shaft of the stop block 16034. The movable end of the torsion spring 16035 is connected to the stop block 16034, and its fixed end is connected to the hinge groove 16033. Connected to each other, a torsion spring 16035 provides the torque to force the abutment 16034 to extend out of the hinge groove 16033, so that the abutment 16034 can abut against and engage with the ratchet groove 16031. Multiple sliding grooves 1604 are annularly distributed on the outer side of the cylindrical block 1602, with three sliding grooves 1604 in total. A sliding plate 1605 is slidably fitted within each sliding groove 1604, and the sliding plate 1605 and the sliding groove 1604 are connected by a compression spring 1606. Connected to each other, the compression spring 1606 provides the thrust that forces the sliding plate 1605 out of the sliding groove 1604, and its extended end slides against the inner wall of the cylindrical box 1601. The cylindrical box 1601 is connected to a suction pipe 1607 and a discharge pipe 1608, which are located on opposite sides of the contact area between the cylindrical box 1601 and the cylindrical block 1602, respectively, and pass through the dispensing tank 11 and the dispensing chamber 15. Figure 14 As shown, the structure here is similar to an eccentric pump. The extended adjacent sliding plates 1605, together with the inner wall of the cylindrical box 1601, can form a closed space. As the cylindrical block 1602 rotates, liquid can enter the formed space from the air inlet pipe. When the extended sliding plates 1605 retract into the sliding groove 1604 under the contact of the inner wall of the cylindrical box 1601, the volume of the formed space becomes smaller, compresses the liquid inside, and pushes it towards the liquid outlet pipe 1608, thereby playing the role of pumping high-salt wastewater. It should be specifically noted that the motor 22 operates at a low speed, designed to generate sound waves of a stable frequency, rather than at high speed. Low-speed operation significantly reduces the impact frequency and wear rate between the arc-shaped protrusion 23 and the actuating spring 25. In this application, the column 36 is linked to the cylindrical block 1602. When the motor 22 drives the column 36 to rotate slowly in the forward direction, the abutment 16034 can slide on the inclined surface of the ratchet teeth within the ratchet groove 16031. At this time, the arc-shaped protrusion 23 on the outer side of the column 36 will actuate the spring 25. The arc-shaped protrusion 23 will not impact the spring 25. When the spring 25 is in contact at high speed, the cylindrical block 1602 does not move with the rotation of the column 36. When the motor 22 drives the column 36 to rotate in the opposite direction, the abutment 16034 abuts against the ratchet in the ratchet groove 16031. At this time, the arc-shaped protrusion 23 on the outside of the column 36 will actuate the spring 25, and the cylindrical block 1602 will move with the rotation of the column 36. In summary, the structural principle of the liquid pumping assembly 16 is sufficient to achieve the pumping of high-salt wastewater even when the cylindrical block 1602 rotates slowly. The column 36, soundboard 24, reed 25, rod 19, and other structures are all made of 316L stainless steel, which has corrosion resistance. As mentioned above, the actuating reed 25 is located within the liquid distribution chamber 15, not within the heat-conducting pipe 13 that generates steam. This is because the medium in the liquid distribution chamber 15 is residual high-salt wastewater drawn from the liquid distribution tank 11, and... Figure 12 As shown, due to the height difference, the actuating spring 25 will not even come into contact with the high-salt wastewater, thus ensuring that the above structure is not easily corroded.

[0023] like Figure 7 , Figure 8 and Figure 12 As shown, a further technical solution of this application is disclosed. The mounting plate 14 and the separating tank 11 are detachably connected by a bolt assembly. A cover plate 28 is detachably installed on the top of the mounting plate 14. The cover plate 28 is connected to the mounting plate 14 by a bolt assembly to cover the separating chamber 15. The column 36, the motor 22, and the cylindrical box 1601 are all mounted on the cover plate 28. A vertical pipe 29 is constructed at the bottom of the mounting plate 14. The liquid extraction pipe 1607 is threadedly connected to the top of the vertical pipe 29. The bottom end of the liquid outlet pipe 1608 passes through the cover plate 28. By removing the mounting plate 14 from the separating tank 11, the separating tank 11 and the heat-conducting pipe 13 inside it can be cleaned. Figure 12 As shown, by disconnecting the liquid extraction pipe 1607 from the vertical pipe 29 and removing the cover plate 28 from the mounting plate 14, the liquid separation chamber 15 can be opened for cleaning. This application designs the wastewater treatment device as a modular installation, which facilitates disassembly and cleaning of internal impurities.

[0024] like Figures 1-3As shown, a further technical solution of this application is disclosed. A vapor-liquid separator 30 is installed on the outside of the collection tank 1. The vapor-liquid separator 30 can be a gravity settling separator. Its input end is connected to the exhaust port 3 and the outlet pipe 8. The cooling steam in the cylindrical box 4 and the secondary steam formed by the evaporation of high-salt wastewater in the collection tank 1 can be separated into vapor and liquid under the action of the vapor-liquid separator 30. The output end of the vapor-liquid separator 30 is connected to a steam compressor 31 and is connected to a steam pipe 6. The vapor-liquid separator 30 can input pure secondary steam into the steam compressor 31, and then the secondary steam is compressed and heated by the steam compressor 31. Subsequently, the heated secondary steam enters the heat preservation box 5 through the steam pipe 6 to reheat the high-salt wastewater in the heat conduction pipe 13, thereby making full use of the latent heat of the secondary steam.

[0025] like Figure 3 and Figure 11 As shown, a further technical solution of this application is disclosed. An annular groove 32 is constructed on the bottom surface of the cylindrical box 4. Cooling water generated by steam condensation enters the annular groove 32 of the cylindrical box 4. The outlet pipe 9 is U-shaped, with its inlet end inserted into the annular groove 32. A liquid storage tank 33 is fixed to the outside of the collection bucket 1. A portion of water is pre-stored in the liquid storage tank 33. The outlet end of the U-shaped pipe passes through the liquid storage tank 33. An outlet 34 is constructed at the top of the liquid storage tank 33. Due to the resistance of the water in the outlet end of the U-shaped pipe, the water in the cylindrical box 4... Steam will not be discharged from the outlet pipe 9. After a period of use, when the cooling water in the cylindrical box 4 overflows the inlet end of the outlet pipe 9 and fills the annular groove 32, the steam input of the steam pipe 6 can be increased to compress the gas in the cylindrical box 4, thereby applying pressure to the condensate in the annular groove 32. This drives the condensate in the annular groove 32 to enter the storage tank 33 through the outlet pipe 9, thus achieving the separation and discharge of condensate and steam. At the same time, excess condensate can be discharged from the storage tank 33 through the outlet 34.

[0026] like Figure 5 , Figure 6 and Figure 11 As shown, a further technical solution of this application is disclosed. A gas guide plate 35 is connected to the inner wall of the heat exchange tube 7. The gas guide plate 35 is a rubber plate and is spiral in shape. It contacts the outer side of the heat conduction tube 13. It should be specifically noted that the width of the gas guide plate 35 is greater than the distance between the heat exchange tube 7 and the heat conduction tube 13. When the heat conduction tube 13 is inserted into the heat exchange tube 7, the gas guide plate 35 will tilt slightly under the action of the heat conduction tube 13. At the same time, the gas guide plate 35 will also be in close contact with the outer wall of the heat conduction tube 13. By adopting the design of the gas guide plate 35, the time for steam to pass through the distance between the heat exchange tube 7 and the heat conduction tube 13 can be extended, thereby improving the heating efficiency of the steam on the heat conduction tube 13.

[0027] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
