Description

Technical Field

[0001] This invention relates to the technical field of adsorption and separation devices for dyeing and printing wastewater, and in particular to an integrated adsorption and separation device and method for deep treatment of wastewater. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0004] Currently, the mainstream devices for adsorption separation of dyeing and printing wastewater include fixed beds, fluidized beds, and moving beds. Among them, fluidized beds are the preferred equipment in industrial applications due to their high adsorption efficiency, excellent mass transfer effect, and large processing capacity. Adsorption separation devices can be divided into three categories based on the differences in bed state: fixed beds, fluidized beds, and moving beds. The dynamic adsorption process of fluidized beds can effectively avoid the clogging problem of fixed beds, and has advantages in mass transfer efficiency and processing flexibility. However, existing fluidized bed devices suffer from low adsorbent utilization due to uneven internal flow field distribution. Directly applying them to the treatment of high-concentration dyeing and printing wastewater can lead to large adsorbent losses and unstable separation effects, thereby increasing operating costs.

[0005] Currently, most wastewater treatment systems suffer from the following problems: The device's structural design lacks rationality, resulting in insufficient adsorption reaction and poor overall wastewater treatment capacity. Furthermore, after treatment, it needs to be passed through a solid-liquid separator for solid-liquid separation, leading to low solid-liquid separation efficiency. Some solutions simply discard both wastewater and carbon water, making it difficult to effectively recover carbon water resources. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an integrated adsorption and separation device for deep wastewater treatment. The device has a reasonable structure, and the carbon water and dyeing wastewater can be effectively contacted to improve the purification effect and facilitate the rapid separation of the purified wastewater and carbon water.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: An integrated adsorption and separation device for advanced wastewater treatment includes: The tank body is secured; The cavity is located on the top side of the tank. The cavity includes an inner cavity and an outer cavity. One of the inner cavity and the other of the outer cavity is filled with molten carbon and wastewater. The adsorption separation unit is placed inside the tank. Multiple adsorption separation unit components are arranged along the height of the tank. The top of each adsorption separation unit component is connected to both the inner and outer cavities. The connection points between the adsorption separation unit components and the inner and outer cavities are arranged opposite each other. Inside the adsorption separation unit component, from high to low, there are swirling elements and conical elements. The swirling elements can rotate to separate the purified wastewater and carbon water. The conical elements are hollow to separate the purified wastewater and carbon water. The swirling elements and conical elements are spaced apart. An outlet is provided at the bottom of the adsorption separation unit component.

[0008] As described above, an integrated adsorption and separation device for deep wastewater treatment includes an adsorption and separation unit component comprising a shell, a narrowed section at the connection between the top and middle of the shell, and a swirling element disposed inside the narrowed section, wherein the diameter of the swirling element is smaller than the inner diameter of the smaller side of the shell. The swirl guide vane includes a guide post with an arc-shaped surface at the top. The guide post is circumferentially arranged with helical blades, the height of which is less than the height of the guide post. The end of the guide post near the conical member is recessed.

[0009] As described above, in an integrated adsorption and separation device for deep wastewater treatment, the conical component has a set height, which is higher than the height of the cyclone component. The height of the conical component is 1 / 4 to 2 / 5 of the height of the adsorption and separation unit assembly. The end of the conical component with a smaller diameter is located close to the cyclone component, while the end of the conical component with a larger diameter is smaller than the inner diameter of the adsorption and separation unit assembly. The distance between the conical component and the cyclone component is less than the height of the cyclone component.

[0010] As described above, in an integrated adsorption and separation device for advanced wastewater treatment, the external of the adsorption and separation unit is fixedly connected to the tank.

[0011] As described above, the integrated adsorption and separation device for deep wastewater treatment comprises, from top to bottom, a first section, a second section, and a third section connected in sequence. The first and second sections are cylindrical structural components, and the bottom of the third section is an arc-shaped bottom. The first and second sections are connected to each other, and the second and third sections are connected to each other via flanges.

[0012] As described above, in an integrated adsorption and separation device for deep wastewater treatment, the adsorption and separation unit is provided with a circumferential connecting flange, which is connected to a support plate. The support plate is welded to a flange used to connect the various sections of the tank.

[0013] As described above, in an integrated adsorption and separation device for deep wastewater treatment, the bottom of the inner cavity is connected to the adsorption and separation unit assembly via a carbon water inlet pipe, and the bottom of the outer cavity is connected to the adsorption and separation unit assembly via a dyeing and printing wastewater inlet section. The carbon water inlet pipe and the dyeing and printing wastewater inlet section connected to the same adsorption and separation unit assembly are arranged opposite to each other.

[0014] As described above, an integrated adsorption and separation device for deep wastewater treatment has a carbon water outlet on one side of the bottom of the outer shell. The carbon water outlet is connected to the outer space of the conical component. The carbon water outlet is connected to a carbon water outlet tank, which is positioned between multiple adsorption and separation unit components. The bottom of the carbon water outlet tank is connected to a pipeline, which passes through a drain outlet at the bottom of the tank. The diameter of the drain outlet is larger than the outer diameter of the pipeline.

[0015] As described above, an integrated adsorption and separation device for deep wastewater treatment has a purified wastewater outlet at the bottom of the outer shell. The purified wastewater outlet is connected to the space of the inner wall of the conical component. The purified wastewater outlet is connected to a purified wastewater outlet pipeline, which passes through the bottom of the tank.

[0016] Secondly, the present invention also provides an adsorption separation method for the deep treatment of dyeing and printing wastewater, employing the aforementioned integrated adsorption and separation device for deep wastewater treatment, comprising the following components: Charcoal water and dyeing wastewater are introduced into one of the inner or outer cavities; The activated carbon in the charcoal solution and the dyeing and printing wastewater are mixed in the adsorption separation unit, and the dyeing and printing wastewater is adsorbed and treated by the activated carbon in the charcoal solution. After the dyeing and printing wastewater is purified, the wastewater and carbon water pass through a cyclone separator. The cyclone separator rotates to separate the purified wastewater and carbon water. The purified wastewater and carbon water continue to flow through a hollow conical part. The hollow conical part separates the purified wastewater and carbon water. The purified wastewater and carbon water are discharged from the outlet at the bottom of the adsorption separation unit and collected separately.

[0017] The beneficial effects of the present invention are as follows: The entire device has cavities inside the tank. Dyeing wastewater and charcoal water enter the inner and outer cavities respectively, and then enter the adsorption separation unit. The connection points between the adsorption separation unit and the inner cavity, and between the adsorption separation unit and the outer cavity, are arranged opposite each other. This allows the charcoal water and wastewater to form an impact flow after entering the adsorption separation unit, ensuring sufficient contact between the charcoal water and wastewater and improving the removal efficiency of pollutants. Because the gravity of the charcoal water is different from that of the purified wastewater, the swirling component facilitates the separation of the charcoal water and the purified wastewater. The hollow conical component separates the purified wastewater and charcoal water, allowing the purified wastewater to flow inside the conical component and the charcoal water to flow outside, achieving complete separation of the two. While ensuring high-efficiency mass transfer, the overall design optimizes the internal structure to achieve uniform contact and efficient separation between the adsorbent and wastewater. This improves treatment efficiency while reducing adsorbent loss. The purified wastewater and charcoal water can be recycled separately after separation, reducing water waste and environmental pollution. Attached Figure Description

[0030] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. As described in the background section, the existing technology suffers from poor wastewater treatment capacity and low separation efficiency between purified wastewater and carbon water. In order to solve the above technical problems, this invention proposes an integrated adsorption and separation device for deep wastewater treatment.

[0032] Example 1 In a typical embodiment of the present invention, reference is made to Figure 1 As shown, an integrated adsorption and separation device for advanced wastewater treatment includes: Tank 5, tank 5 is fixed; The cavity is located on the top side inside the tank 5. The cavity includes an inner cavity 11 and an outer cavity 12. One of the inner cavity 11 and the outer cavity 12 is filled with activated carbon water, and the other is filled with wastewater. The activated carbon water is a suspension of activated carbon and water. The activated carbon in the activated carbon water is used to adsorb pollutant particles in the dyeing and printing wastewater. The adsorption separation unit is placed inside the tank 5. Multiple adsorption separation unit components are arranged along the height of the tank 5. The top of the adsorption separation unit components are connected to both the inner cavity 11 and the outer cavity 12. The connection points between the adsorption separation unit components and the inner cavity 11 and the outer cavity 12 are arranged opposite each other to ensure that the carbon water and dyeing wastewater can fully contact each other after entering the adsorption separation unit components, thereby improving the removal efficiency of pollutants. The adsorption separation unit components are arranged with cyclone elements and conical elements from high to low inside. The cyclone elements can rotate to separate the purified wastewater and carbon water. The conical elements are hollow to separate the purified wastewater and carbon water. The cyclone elements and conical elements are spaced apart. An outlet is provided at the bottom of the adsorption separation unit components.

[0033] In this embodiment, the tank body 5, from top to bottom, includes a first segment 1, a second segment 2, and a third segment 3 connected in sequence. The first segment 1 and the second segment 2 are both cylindrical structural components, and the bottom of the third segment is an arc-shaped bottom. A first flange 6 is provided at the top of the first segment 1. The first segment 1 and the second segment 2 are connected by a second flange 7, and the second segment 2 and the third segment 3 are connected by a third flange 8. The bottom of the third segment of the tank body is supported by a support foot 28, and a support 24 is provided at the bottom of the support foot 28. The tank body 5 is fixed to the ground by the support 24, realizing the load-bearing and support of the tank body 5. The multiple segments of the tank body 5 are connected by flange structural components, which enhances the replaceability of the device, facilitates maintenance, and facilitates the installation of the internal adsorption and separation unit components.

[0034] It is easy to understand that a drain port 25 is opened at the bottom of the tank body 5. The drain port 25 is normally open to realize daily sewage discharge or to determine whether there is any leakage inside the device, so that timely inspection and maintenance can be carried out.

[0035] Additionally, a manhole 23 is provided in the second section 2 of tank body 5, and is sealed by an openable cover. When maintenance is required, technicians open the manhole 23 to inspect the internal condition and perform repairs.

[0036] A cavity is provided on the top side inside tank 5, for reference. Figure 2As shown, the center of the cavity is the inner cavity 11, and the outer side is the outer cavity 12. The top of the tank 5 is provided with a carbon water inlet 9 and a dyeing and printing wastewater inlet 10, which pass through the top surface of the tank 5. The carbon water inlet 9 is connected to the inner cavity 11, and the dyeing and printing wastewater inlet 10 is connected to the outer cavity 12. The height of the cavity is less than the height of the first section 1 in the tank 5. The bottom of the inner cavity 11 is connected to the corresponding adsorption separation unit component through the carbon water inlet / outlet pipe 13, and the bottom of the outer cavity 12 is connected to the corresponding adsorption separation unit component through the dyeing and printing wastewater inlet / outlet section 14. In order to ensure that the carbon water and dyeing and printing wastewater flow fully into the inlet section 13 and the dyeing and printing wastewater inlet / outlet section 14, the connection between the two and the bottom of the inner cavity 11 and the outer cavity 12 can be flush with or slightly lower than the bottom surface of the cavity. The dyeing and printing wastewater and carbon water first enter the inner cavity or the outer cavity to accumulate the fluid velocity, and then enter the adsorption separation unit component to ensure the velocity of entering the adsorption separation unit component.

[0037] Among them, the carbon-water inlet pipe 13 and the dyeing and printing wastewater inlet section 14, which are connected to the same adsorption and separation monomer component, are arranged opposite to each other, as shown in the reference. Figure 3 As shown, an impact section 15 is formed on the top side of the adsorption and separation monomer component, so that the carbon water forms a carbon water flow and the dyeing wastewater forms a dyeing wastewater flow, which facilitates full contact between the two at the impact section 15 and ensures the adsorption effect of the carbon water on pollutants.

[0038] In this embodiment, both the charcoal water inlet 9 and the dyeing wastewater inlet 10 are pipeline structural components, welded integrally to the first flange 6. The charcoal water inlet (for receiving charcoal) and the dyeing wastewater inlet (for receiving wastewater) are directly inserted into the inner cavity 11 and outer cavity 12 respectively, ensuring separate inputs without interference. To ensure sealing, soft gaskets are placed at the interfaces of the inner cavity 11 and outer cavity 12, and hard gaskets are welded to the points where the charcoal water inlet 9 and the dyeing wastewater inlet 10 meet the soft gaskets. Furthermore, the upper ends of the charcoal water inlet 9 and the dyeing wastewater inlet 10 are connected to the pipeline to be connected by flange structural components.

[0039] It should be noted that the cavity covers of the inner cavity 11 and the outer cavity 12 are designed to be narrow at the bottom and wide at the top. To ensure the load-bearing capacity of the inner cavity 11 and the outer cavity 12, hard gaskets 35 are welded below the connection between the four carbon water inlet sections 13 and the four dyeing waste water inlet sections 14 and the cavity body.

[0040] Multiple sets of adsorption separation unit components are arranged along the height of the tank 5. The central axes of the multiple sets of adsorption separation unit components are parallel to each other, specifically four sets. The interval between two adjacent adsorption separation unit components is set at a certain angle. In this embodiment, the device connects four sets of adsorption separation unit components in parallel, which greatly saves space and achieves more efficient treatment of dyeing and printing wastewater. This also controls the inner diameter of each set of adsorption separation unit components, which helps to ensure the flow rate of activated carbon water flow and dyeing and printing wastewater flow into the adsorption separation unit components, which is conducive to sufficient contact between activated carbon and dyeing and printing wastewater, and helps to improve the adsorption quality.

[0041] In this embodiment, the adsorption and separation monomer assembly includes a housing 16, which is cylindrical in shape. Figure 5 As shown, the outer shell 16 is circumferentially provided with two support plates 26 of a set thickness. The support plates 26 are iron plates. The connecting flanges 29 are fixed to the outer shell 16 in the circumferential direction and are located in the middle and bottom of the outer shell 16. The connecting flange 29 in the middle is connected to the support plate 26 in the middle. After the support plate 26 in the middle is connected to the connecting flange 29 in the middle, it is welded to the second flange 7. The connecting flange 29 at the bottom is connected to the third flange 8 and then welded to the third flange 8. The four sets of adsorption separation unit components are fixed inside the tank 5 through the connecting flanges 29 and the support plates 26.

[0042] It is easy to understand that the inner diameter of the top of the outer casing 16, i.e., the impact section 15, is larger than the inner diameter of the middle and bottom sections, for reference. Figure 4 As shown, a narrowing section 4 is provided at the connection between the top and middle of the outer shell 16. A swirling element is provided at the connection between the narrowing section 4 and the middle. The swirling element is a swirling guide vane 17. The swirling element is located inside the narrowing section 4. The diameter of the swirling element is smaller than the inner diameter of the smaller inner diameter side of the outer shell 16. refer to Figure 7 and Figure 8 As shown, the swirl guide vane 17 includes a guide post 31 with an arc-shaped top and a semi-elliptical longitudinal section. The top of the guide post 31 guides and disperses the water flow. The top of the guide post is located in the narrowed section of the outer shell 16. The guide post 31 is circumferentially arranged with helical blades 32. The height of the helical blades 32 is less than the height of the guide post 31. The top of the helical blades 32 and the top of the guide post 31 are spaced apart, and the bottom of the helical blades 32 and the bottom of the guide post 31 are also spaced apart. The end of the helical blades 32 near the bottom of the guide post 31 is sharp to facilitate the water flow from the helical blades. The bottom of the guide post 31 has a recess in a semi-circular shape, which forms a flow nozzle at the bottom of the guide post 31 to form a high-speed fine swirling flow. The outer diameter of the guide post 31 is greater than the maximum outer diameter of the conical part. The distance between the swirl guide vane 17 and the top of the conical part 18 is less than the height of the swirl guide vane 17 to facilitate the high-speed fine swirling flow entering the interior of the conical part 18.

[0043] It is easy to understand that the connection section between the carbon water inlet section 13, the dyeing waste water inlet section 14 and the shell 16 is a horizontal section. Combined with the smooth and flowing shape of the shell 16, the mixed flow can be guided into the spiral blade 32 to form a high-speed swirling flow. In some examples, the spiral blade 32 uses four swirling guide vanes arranged at equal angles. Compared with three vanes, this can avoid the problem of mixing and deflection of two feed streams caused by circumferential flow field eccentricity and uneven swirling distribution. Compared with six or more vanes, it can reduce flow resistance and dead angles of material accumulation. This arrangement can uniformly apply circumferential guiding torque to the fluid, match the dual-inlet confluence condition to achieve smooth tangential reversal of axial flow, and ensure the symmetrical and stable swirling field. It needs to be explained that a hollow conical component is provided on the inner side of the bottom of the outer shell 16. The conical component is a cone-shaped body 18. The design of the conical component is to ensure the effective separation of carbon water and adsorbed wastewater. The volume of the inner wall of the separation chamber is reduced, so that the fluid space is compressed and discharged more quickly. After the unseparated mixed water passes through the swirl guide vane 17, the carbon water, due to its higher density, will be thrown towards the inner wall surface by a greater centrifugal force and discharged downstream. The carbon water that is not thrown to the wall surface will flow along the outer wall of the conical component to the bottom and be discharged together due to its higher density. The adsorbed wastewater, due to its lower density, will generate a high-velocity internal swirling flow. The internal swirling flow rises and passes through the guide nozzle (the concave part at the bottom of the swirl guide vane 17), where the fluid is turned to form a high-speed fine swirling flow, and then discharged from the hollow part inside the conical component.

[0044] refer to Figure 9 As shown, the cone 18 is a slender structural component. The cone uses the swirl guide vane 17 to create a strong swirling flow between the purified wastewater and the carbon water. The cone 18 then separates the purified wastewater and carbon water. Specifically, the cone has a set height, which is higher than the height of the swirling component. The cone angle is 80°-88°, with an optimal value of 86°, to ensure effective guidance of the water flow. The height of the cone is 1 / 4-2 / 5 of the height of the adsorption separation unit component. The end of the cone with the smaller diameter is positioned closer to the swirling component, while the end with the larger diameter is smaller than the inner diameter of the adsorption separation unit component. The end with the larger diameter is less than or equal to half the inner diameter of the outer shell 16. The reasonable setting of the height and diameter of the cone effectively separates the purified wastewater and carbon water. The carbon water flows through the outer wall of the cone, while the purified wastewater flows through the inner wall of the cone.

[0045] Additionally, the bottom of the outer shell 16, near the third flange, connects to the carbon outlet 19. The adsorbed carbon flows from the four carbon outlets 19 to the carbon outlet tank 27, and is discharged via the carbon discharge pipe 22. The carbon discharge pipe 22 passes through the drain port 25 at the bottom of the third section of the tank body 5. The carbon outlet tank 27 is positioned at the center of the four adsorption and separation unit components. The carbon discharge pipe 22 is connected to the pipeline to be connected via a flange structure. (Refer to...) Figure 6As shown, a can cover 30 is provided on the top of the charcoal outlet tank 27. The can cover 30 is fixed by two connecting flanges 29 at the bottom. The can cover 30 is connected to the charcoal outlet tank 27 by screws to ensure load-bearing capacity. Four charcoal outlets 19 are set through the can cover 30.

[0046] The bottom of the outer shell 16 is provided with a purified wastewater outlet 20 in the third section. The purified wastewater discharged from the purified wastewater outlet 20 is directly discharged from the entire tank through a purified wastewater outlet pipe 21 connected by three tees. The purified wastewater outlet pipe is set through the bottom of the third section of the tank 5. The bottom of the purified wastewater outlet pipe 21 is connected to the pipeline to be connected by a flange. After the wastewater and carbon water are separated by cyclone separation, the wastewater flows from the cone 18 to the purified wastewater outlet 20, and the carbon water flows to the carbon water outlet 19, thereby improving the separation efficiency.

[0047] For optimal connectivity, two holes are provided on the lower side of tank 5: one for a drain outlet and the other for the installation of the purified wastewater outlet pipe 21. The aforementioned carbon discharge pipe 22 and purified wastewater outlet pipe 21 do not require redesign; they can be easily separated upon discharge and disassembled.

[0048] The charcoal and dyeing wastewater to be treated enter the inner cavity 11 and outer cavity 12 respectively from the charcoal inlet 9 and the dyeing wastewater inlet 10. They then enter the adsorption separation unit component via four charcoal inlet / outlet pipes 13 and four dyeing wastewater inlet / outlet sections 14. After entering, the wastewater and charcoal are fully mixed and adsorbed in four impact sections 15. After adsorption, the wastewater and charcoal mixture enters the narrowing section 4, generating a high-speed swirling flow. Due to the density difference, they separate and continue flowing downwards, passing through the cone 18 for further adsorption. The adsorbed charcoal flows from the four charcoal outlets 19 to the charcoal outlet tank and is discharged through the charcoal discharge pipe 22. The purified wastewater is purified through the cone 18 inside the adsorption separation unit component and then discharged through the purified wastewater outlet 20 and the purified wastewater outlet pipe 21. If there is leakage or overflow inside the tank 5, the wastewater is discharged from the drain port 25 at the bottom of the tank.

[0049] The device provided in this embodiment can achieve efficient adsorption and separation in the treatment of dyeing and printing wastewater, and increases the treatment capacity compared to a single adsorption device, enabling the treatment of large quantities of dyeing and printing wastewater in a single operation. Furthermore, this adsorption and separation device adopts a modular design with four individual units connected in parallel within the same tank. It achieves efficient integrated installation through a synergistic mechanism of enhanced adsorption by impinging flow and enhanced separation of carbon water and wastewater by cyclone flow. Integrating a high-efficiency adsorption and separation device into the dyeing and printing wastewater conveying pipeline, achieving simultaneous wastewater conveyance and treatment, is a key measure to reduce pollutant load and improve resource recovery efficiency. It can significantly improve wastewater treatment effects and also achieve the recycling of adsorbents through carbon water separation. This device has a compact and modular structure, is easy to load and unload, has high adsorption and separation efficiency, and controllable operation and maintenance costs, making it suitable for long-term operation in continuous production in dyeing and printing enterprises. It should be noted that the device described in this application can be used for adsorption treatment of pollutants in other wastewaters, as long as they can be adsorbed by carbon water.

[0050] Example 2 This embodiment discloses an adsorption separation method for the advanced treatment of dyeing and printing wastewater, employing an integrated adsorption separation device for advanced wastewater treatment as described in Embodiment 1, including the following: Charcoal water and dyeing wastewater are introduced into one of the inner or outer cavities; The activated carbon and dyeing wastewater are mixed in the adsorption separation unit. The connection between the adsorption separation unit and the inner cavity and the connection between the adsorption separation unit and the outer cavity are set opposite to each other so that the activated carbon and wastewater form an impact flow after entering the adsorption separation unit, so that the activated carbon and wastewater can fully contact each other and the dyeing wastewater is adsorbed by the activated carbon in the activated carbon. After the dyeing and printing wastewater is purified, the wastewater and charcoal water pass through a cyclone separator. The cyclone separator rotates to separate the purified wastewater and charcoal water. The purified wastewater and charcoal water continue to flow through a hollow conical part. The hollow conical part separates the purified wastewater and charcoal water. The purified wastewater is discharged through the bottom of the shell, and the charcoal water is discharged into the charcoal water outlet tank 27 through the charcoal water outlet at the bottom of the shell and then discharged. In this way, the purified wastewater and charcoal water can be recycled separately.
