Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a device for treating high-salinity organic wastewater. Background Technology

[0002] High-salinity organic wastewater, due to its excessively high salt content, usually requires desalination to prevent pollution and facilitate resource recovery. However, during the treatment process, existing high-salinity organic wastewater treatment devices are prone to localized thermal stress corrosion or thermal decomposition and polymerization reactions due to uneven temperature and pressure, which affects the treatment effect on high-salinity organic wastewater.

[0003] Therefore, this utility model provides a device for treating high-salinity organic wastewater to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing treatment of high-salinity organic wastewater is easily affected by uneven local temperature and pressure.

[0005] This utility model provides the following technical solution: a high-salinity organic wastewater treatment device, comprising a wall and an evaporation structure. The evaporation structure is installed inside the wall, and the evaporation structure includes a heating chamber and a separation chamber. An inclined separation chamber is arranged above the heating chamber. An inclined isolation wall is fixedly installed between the heating chamber and the separation chamber. An air inlet is opened at the highest horizontal position of the isolation wall. A baffle tube inclined in the opposite direction to the isolation wall is fixedly installed inside the separation chamber. The horizontal low-end inlet of the baffle tube is connected to the air inlet. There are at least two heating chambers and separation chambers arranged longitudinally. A connecting pipe connecting to the upper baffle tube is fixedly installed at the highest horizontal position of the baffle tube.

[0006] A heating element is fixedly installed on the outside of the heating cavity.

[0007] The baffle tube is fixedly installed with fins that are bent or staggered to change the airflow direction, and the fins at the top of the baffle tube extend through and connect to the interior of the upper heating chamber.

[0008] The baffle tube has a flow channel at its horizontal bottom, and a conveying pipe is fixedly installed at the horizontal low end of the flow channel. The other end of the conveying pipe is fixedly connected to the heating chamber.

[0009] A drive body is fixedly installed at the top of the bottom heating cavity, and a rotating shaft that passes through the bottom wall and is fixed coaxially with the drive body is rotatably installed inside the heating cavity. A scraper is fixedly installed on the surface of the rotating shaft.

[0010] The fins inside the baffle tube are bent in a wave-like structure.

[0011] The horizontal lower section of the baffle plate is fixedly installed with a perforated plate.

[0012] The scraper body includes an outer scraper, an upper inner scraper body, and a lower inner scraper body. The upper inner scraper body and the lower inner scraper body, which slide in opposite directions, are slidably installed inside the outer scraper body.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model has multiple heating chambers and separation chambers that can simultaneously treat wastewater, improving treatment efficiency. Furthermore, during treatment, multiple baffles are connected by connecting pipes to achieve thermal coupling, ensuring stable pressure and temperature between them. At the same time, they can also work with fins to ensure stable temperature balance between multiple heating chambers and baffles, thereby avoiding thermal stress corrosion caused by sudden temperature changes or thermal decomposition or polymerization reactions caused by local overheating. This helps to ensure the stability of the evaporation process and improves the effect of evaporating and removing salt from high-salinity organic wastewater.

[0015] 2. In this utility model, the baffle plate, through its wave structure, can increase the surface area, improve heat transfer efficiency, and extend the contact path with salt spray, thereby enhancing the effect of maintaining temperature balance and stability and removing salt spray. At the same time, the perforated plate ensures that the steam is evenly distributed along the cross-section, avoiding local temperature anomalies caused by flow deviation, which is conducive to improving the temperature stability inside the baffle tube. Furthermore, during the treatment process, the rotating shaft passes through multiple heating chambers and works with the scraper to stir the wastewater, ensuring uniform temperature and preventing sedimentation. On the other hand, it can also prevent salts from adhering to the inner wall and forming scale. Attached Figure Description

[0026] To address the problem that existing high-salinity organic wastewater treatment methods are prone to affecting treatment efficiency due to uneven local temperature and pressure, this disclosure provides a high-salinity organic wastewater treatment device, including a wall 1 and an evaporation structure. The evaporation structure is installed inside the wall 1, and includes a heating chamber 2 and a separation chamber 3. The separation chamber 3 is located above the heating chamber 2. An inclined isolation wall 4 is fixedly installed between the heating chamber 2 and the separation chamber 3. An air inlet 5 is opened at the highest horizontal position of the isolation wall 4. A baffle tube 6, inclined in the opposite direction to the isolation wall 4, is fixedly installed at the top of the separation chamber 3. The horizontal lower end inlet of the baffle tube 6 is connected to the air inlet 5.

[0027] The heating chamber 2 has a liquid inlet 11 fixedly connected to its side wall, and the upper horizontal end of the baffle tube 6 is connected to the external condenser 13. The isolation wall 4 separates the heating chamber 2 and the separation chamber 3. The top wall of the separation chamber 3 is parallel to the baffle tube 6, so that the bottom of the upper heating chamber 2 is inclined, which facilitates the discharge of the concentrated liquid after evaporation.

[0028] High-salinity organic wastewater enters through inlet 11 and is heated to form steam. The steam rises and contacts the isolation wall 4, moving upwards along the isolation wall 4. It then enters the baffle tube 6 through inlet 5, where salt mist is separated. The remaining pure steam, free of salt, enters the external condenser 13 for condensation, ensuring that the high-salinity organic wastewater is free of salt after treatment. This facilitates subsequent treatment and resource recovery, thereby improving the treatment efficiency of high-salinity organic wastewater.

[0029] The heating chamber 2 and the separation chamber 3 are arranged in a longitudinal array of at least two. At least two heating chambers 2 and separation chambers 3 can simultaneously treat high-salinity organic wastewater, thereby improving the efficiency of treating high-salinity organic wastewater.

[0030] It should be noted that in this embodiment, each heating chamber 2 has a liquid inlet 11 fixedly installed on its side wall for independent feeding. The remaining concentrated salt solution after heating can be discharged through the liquid outlet 12 fixedly connected to the side wall.

[0031] A connecting pipe 61 is fixedly installed at the highest horizontal point of the baffle tube 6, connecting to the upper baffle tube 6. The connecting pipe 61 connects the different baffle tubes 6, thereby maintaining a balance in pressure, flow rate, and temperature across the multiple baffle tubes 6, achieving thermodynamic coupling. Specifically, under the influence of gravity and flow resistance, the steam or liquid in the interconnected baffle tubes 6 spontaneously adjusts the pressure in each area through the connecting pipe 61, eliminating localized high or low pressure, and adjusting the temperature in each part through thermosiphon, thereby inhibiting scaling and improving the stability of the separated salt spray.

[0032] A heating element 7 is fixedly installed on the outside of the heating chamber 2. The heating element 7 includes a jacket 71 and a heat source 72. The jacket 71 is detachably installed on the outside of the heating chamber 2, and the heat source 72, which heats the heating chamber 2, is fixedly installed in a spiral shape inside the jacket 71. It should be noted that the heat source 72 can be heated by any structure or device in the prior art that can be heated, such as oil and steam pipelines or electric heating wires. In this embodiment, steam pipelines are used for heating, with steam from an external boiler entering the pipelines to heat the heating chamber 2.

[0033] The baffle tube 6 is fixedly installed with bent or staggered fins 62 that change the airflow direction. The fins 62 at the top of the baffle tube 6 extend through and connect to the interior of the upper heating chamber 2. The baffle tube 6 continuously changes the movement direction and trajectory of the steam through the staggered fins 62, causing droplets with higher density and mass to collide with the surface of the fins 62 and slide down and agglomerate along the surface of the fins 62, thereby achieving the separation of salt spray in the steam. Meanwhile, the fins 62 penetrating into the upper heating chamber 2 can also transfer the steam temperature to the upper heating chamber 2, thereby assisting in heating the upper heating chamber 2 and reducing the energy required for heating the upper heating chamber 2. Furthermore, the fins 62 can also maintain the heat stability between the heating chamber 2 and the baffle tube 6, while the baffle tubes 6 can achieve pressure and temperature balance through the thermal coupling of the connecting pipe 61. This ultimately ensures the temperature stability between the multiple heating chambers 2 and the baffle tubes 6, which helps to ensure that the temperature is uniform, stable and controllable throughout the evaporation process. It avoids thermal stress corrosion caused by sudden temperature changes or thermal decomposition or polymerization reactions caused by local overheating, thus helping to ensure the stability of the evaporation process and improve the effect of evaporating and removing salt from high-salinity organic wastewater.

[0034] A flow channel 63 is provided at the horizontal bottom of the baffle tube 6, and a conveying pipe 64 is fixedly installed at the horizontal lower end of the flow channel 63. The other end of the conveying pipe 64 is fixedly connected to the heating chamber 2. The flow channel 63 can guide the liquid collected on the surface of the fins 62 to flow through, so that the liquid formed by the salt spray can re-enter the heating chamber 2 along the flow channel 63 and the conveying pipe 64, which is conducive to the complete collection and discharge of the salt concentrate.

[0035] A drive body 8 is fixedly installed on the top of the heating chamber 2. A rotating shaft 81, which penetrates the bottom wall and is coaxially fixed with the drive body 8, is rotatably installed inside the heating chamber 2. A scraper 82 is fixedly installed on the surface of the rotating shaft 81. During the treatment of high-salinity organic wastewater, the drive body 8 is activated to drive the rotating shaft 81, which in turn drives the scraper 82 to rotate. This agitates the high-salinity organic wastewater, ensuring uniform temperature and preventing sedimentation. Furthermore, it scrapes away salt deposits from the inner wall to prevent scale formation.

[0036] It should be noted that the driving body 8 can adopt any structure in the prior art that can drive the rotating shaft 81 to rotate. In this embodiment, a drive motor is used to drive the rotating shaft 81 to rotate.

[0037] The scraper body 82 includes an outer scraper 821, an upper inner scraper 822, and a lower inner scraper 823. The upper inner scraper 822 and the lower inner scraper 823, which slide in opposite directions, are slidably installed inside the outer scraper 821. When the drive body 8 drives the rotating shaft 81 and the scraper body 82 to rotate, when the upper inner scraper 822 and the lower inner scraper 823, located in the upper heating chamber 2, contact the bottom and top of the inclined heating chamber 2, the upper inner scraper 822 and the lower inner scraper 823 are compressed into the outer body or extend due to their own weight, respectively. This allows the scraper body 82 to stir and scrape the upper and lower inclined heating chamber 2.

[0038] It should be noted that the contact positions of the outer scraper 821, the upper inner scraper 822, and the lower inner scraper 823 with the inner wall of the heating chamber 2 are arc-shaped, so that the outer scraper 821, the upper inner scraper 822, and the lower inner scraper 823 can all contact the inner wall of the heating chamber 2 to achieve complete scraping.

[0039] It should be noted that the movement trajectory of the scraper 82 does not contact the fins 62.

[0040] In the process of treating high-salinity organic wastewater, multiple heating chambers 2 are fed with high-salinity organic wastewater through inlets 11 and heated by heating elements 7 to generate steam. This improves the efficiency of treating high-salinity organic wastewater by combining multiple heating chambers 2 and separation chambers 3. The heated steam rises and contacts the isolation wall 4 and moves along the isolation wall 4, thus entering the baffle tube 6 through the air inlet 5 to separate salt mist.

[0041] The fins 62 inside the baffle tube 6 are bent in a wave-like structure. The bent fins 62 increase the surface area, thereby enhancing heat transfer efficiency and keeping the temperature inside the multiple heating chambers 2 and the baffle tube 6 stable. On the other hand, they also extend the flow contact path to allow for more sufficient contact with the salt spray, thus improving the salt spray removal effect, suppressing mist entrainment, and improving separation efficiency.

[0042] A perforated plate 9 is fixedly installed on the lower horizontal section of the baffle plate. When steam enters the baffle plate, it passes through the perforated plate 9, thereby being evenly distributed along the cross-section of the perforated plate 9. This avoids local temperature anomalies caused by flow deviation and helps to improve the temperature stability inside the baffle tube 6.

[0043] After steam enters the baffle tubes 6, multiple baffle tubes 6 are interconnected through connecting pipes 61, achieving thermal coupling and ensuring uniform and stable pressure and temperature among them. Simultaneously, the steam contacts the staggered fins 62, causing denser and heavier droplets to impact the surface of the fins 62 and slide down and agglomerate, thus separating the salt mist from the steam. The salt mist liquid flows along the flow channel 63 into the delivery pipe 64 and re-enters the heating chamber 2, ensuring complete collection of the salt concentrate. At the same time, the fins 62 maintain a stable temperature between the heating chamber 2 and the baffle tubes 6, ensuring uniform and stable temperature among the multiple heating chambers 2 and the baffle tubes 6. This ensures uniform, stable, and controllable temperature throughout the evaporation process, avoiding thermal stress corrosion caused by sudden temperature changes or thermal decomposition or polymerization reactions caused by localized overheating. This contributes to the stability of the evaporation process and improves the salt removal efficiency of high-salinity organic wastewater. The remaining pure steam after the salt mist is separated in the baffle tubes 6 enters the external condenser 13 for condensation and collection.

[0044] During the heating and evaporation process of high-salinity organic wastewater, the drive unit 8 is activated to drive the rotating shaft 81, which in turn drives the scraper 82 to rotate. This agitates the high-salinity organic wastewater, ensuring uniform temperature and preventing sedimentation. It also scrapes the inner wall to prevent salts from adhering and forming scale.

[0045] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
