Description

Technical Field

[0001] This invention belongs to the field of wastewater flocculation technology, and particularly relates to a supergravity flow stabilization device for enhancing flocculation. Background Technology

[0002] In the wastewater treatment processes of water treatment plants, coal preparation plants, and coking plants, flocculants are added to the wastewater for dewatering. Flocculation refers to the process of adding chemical substances, namely flocculants, to aggregate small particles into larger clusters, thereby accelerating particle sedimentation and facilitating solid-liquid separation. This technology aims to purify wastewater and fully recover and utilize minerals.

[0003] Currently, wastewater flocculation equipment typically includes a thickening tank and a dosing machine. The flocculant is added directly into the wastewater feed pipe, or the flocculant is first added to a mixing tank to mix with the wastewater before being introduced into the thickening tank for treatment.

[0004] However, directly adding flocculant into the wastewater feed pipe cannot achieve the purpose of fully mixing wastewater and flocculant, resulting in uneven distribution of flocculant in wastewater. Although flocculation equipment with a stirring tank can enhance the dispersion of flocculant in wastewater, there are still dead zones in the stirring tank, which leads to insufficient reaction between flocculant and wastewater. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide a supergravity flow stabilization device for enhancing flocculation, which solves the problem in the prior art where insufficient mixing of flocculant and wastewater leads to uneven distribution of flocculant in wastewater.

[0006] The objective of this invention is mainly achieved through the following technical solutions.

[0007] The present invention provides a supergravity flow stabilization device for enhancing flocculation, comprising a supergravity flocculation inner tank disposed within a flow stabilization outer tank of a wastewater treatment system, and an atomizing feeder and an atomizing dosing device disposed within the supergravity flocculation inner tank.

[0008] During the wastewater treatment process, the supergravity flocculation inner tank, atomizing dosing device, and atomizing feeder are always in a state of synchronous rotation relative to the steady flow outer tank.

[0009] Furthermore, the aforementioned supergravity flow stabilization device also includes a flocculant dosing arm and a flocculant atomizing nozzle. The flocculant dosing arm is located on the outer wall of the atomizing dispenser, and the flocculant atomizing nozzle is located at the suspended end of the flocculant dosing arm and is connected to the inner cavity of the atomizing dispenser through the flocculant dosing arm.

[0010] Furthermore, there are multiple flocculant dosing arms and multiple flocculant atomizing nozzles, with each corresponding to the other.

[0011] Furthermore, multiple flocculant dosing arms are evenly arranged around the circumference of the atomizing dosing device.

[0012] Furthermore, the aforementioned supergravity flow stabilization device also includes a wastewater feeding arm and a wastewater feeding port. The wastewater feeding arm is located on the outer wall of the atomizing feeder, and the wastewater feeding port is located at the suspended end of the wastewater feeding arm and is connected to the inner cavity of the atomizing feeder through the wastewater feeding arm.

[0013] Furthermore, there are multiple wastewater feed arms and multiple wastewater feed ports, with each corresponding to the other.

[0014] Furthermore, multiple wastewater feed ports are evenly arranged around the circumference of the atomizing feeder.

[0015] Furthermore, the flocculant atomizing nozzle is located directly below the wastewater feed inlet.

[0016] Furthermore, the angle between the liquid outlet direction of the flocculant atomizing nozzle and the liquid outlet direction of the wastewater feed port, which are located in the vertical direction, is 20° to 60°.

[0017] The aforementioned supergravity flow stabilization device also includes a drive motor for driving the rotation of the supergravity flocculation inner tank, the atomizing dosing device, and the atomizing feeder.

[0018] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0019] A) The supergravity flow stabilization device for enhanced flocculation provided by this invention combines high-speed rotation atomization technology and supergravity technology in the process of wastewater treatment. When the wastewater enters the supergravity flocculation inner tank, it is evenly dispersed and the flocculant and wastewater are evenly distributed to each other, so as to solve the problem of poor coal slurry water concentration effect in coal preparation plants. It can greatly improve flocculation efficiency, shorten settling time, and has a simple overall structure, is easy to operate, has low maintenance cost, and meets the use requirements.

[0020] B) The supergravity flow stabilization device for enhanced flocculation provided by the present invention utilizes the jet cavitation effect. The flocculant is dispersed and atomized into small droplets by an atomizing dosing device. Wastewater is dispersed by an atomizing feeder and then fed into the supergravity flocculation inner tank. In the supergravity flocculation inner tank, the distribution of flocculant in the wastewater is expanded, and the contact area between wastewater and flocculant is increased. The flocculant droplets and the dispersed wastewater can fully contact and mix, thereby effectively improving the flocculation effect.

[0021] C) The supergravity flow stabilization device for enhancing flocculation provided by the present invention, the high-speed rotation of the supergravity flocculation inner barrel can promote the swirling flow of wastewater, greatly prolonging the residence time of wastewater at the bottom of the supergravity flocculation inner barrel. The increase in the collision frequency and collision time between the flocculant and the particles in the wastewater can effectively improve the particle flocculation probability, thereby improving the flocculation effect.

[0022] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention.

Detailed Implementation

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0031] Example 1

[0032] This embodiment provides a high-gravity flow stabilization device for enhancing flocculation. See [link to relevant documentation]. Figure 1The system includes a super gravity flocculation inner tank 1 located inside the stabilizing outer tank of the wastewater treatment system, and an atomizing feeder 2 and an atomizing dosing device 3 located inside the super gravity flocculation inner tank 1. During the wastewater treatment process, the super gravity flocculation inner tank 1, the atomizing dosing device 3, and the atomizing feeder 2 are always in a state of synchronous rotation relative to the stabilizing outer tank.

[0033] Compared with the prior art, the supergravity flow stabilization device for enhanced flocculation provided in this embodiment combines high-speed rotation atomization technology and supergravity technology in the process of wastewater treatment. When the wastewater enters the supergravity flocculation inner tank 1, it is evenly dispersed and the flocculant and wastewater are evenly distributed to each other. This solves the problem of poor coal slurry water concentration effect in coal preparation plants, which can greatly improve flocculation efficiency, shorten settling time, and has a simple overall structure, is easy to operate, has low maintenance cost, and meets the usage requirements.

[0034] For example, the centrifugal force on the fluid and particles in the supergravity flocculation inner tank 1 is 70G to 1000G.

[0035] Specifically, on the one hand, by utilizing the jet cavitation effect, the flocculant is dispersed and atomized into small droplets through the atomizing dosing device 3, and the wastewater is dispersed through the atomizing feeder 2 and then fed into the super gravity flocculation inner tank 1. In the super gravity flocculation inner tank 1, the distribution of flocculant in the wastewater is expanded, the contact area between wastewater and flocculant is increased, and the flocculant droplets and dispersed wastewater can fully contact and mix, thereby effectively improving the flocculation effect.

[0036] On the other hand, the high-speed rotation of the supergravity flocculation inner tank 1 can cause the wastewater to swirl, greatly prolonging the residence time of the wastewater at the bottom of the supergravity flocculation inner tank 1. The increased collision frequency and collision time between the flocculant and the particles in the wastewater can effectively increase the probability of particle flocculation, thereby improving the flocculation effect.

[0037] In order to facilitate the high dispersion of flocculant in the supergravity flocculation inner tank 1 and improve the uniformity of flocculant distribution, the supergravity flow stabilization device for enhancing flocculation also includes a flocculant dosing arm 4 and a flocculant atomizing nozzle 5. The flocculant dosing arm 4 is located on the outer wall of the atomizing dosing device 3, and the flocculant atomizing nozzle 5 is located at the suspended end of the flocculant dosing arm 4 and is connected to the inner cavity of the atomizing dosing device 3 through the flocculant dosing arm 4.

[0038] For example, there are multiple flocculant dosing arms 4 and multiple flocculant atomizing nozzles 5, which correspond one-to-one, and the multiple flocculant dosing arms 4 are evenly arranged along the circumference of the atomizing dosing device 3.

[0039] Accordingly, in order to facilitate the high dispersion of wastewater in the supergravity flocculation inner tank 1 and improve the uniformity of wastewater distribution, the supergravity flow stabilization device for enhancing flocculation also includes a wastewater feeding arm 6 and a wastewater feeding port 7. The wastewater feeding arm 6 is located on the outer wall of the atomizing feeder 2, and the wastewater feeding port 7 is located at the suspended end of the wastewater feeding arm 6 and is connected to the inner cavity of the atomizing feeder 2 through the wastewater feeding arm 6.

[0040] For example, there are multiple wastewater feeding arms 6 and multiple wastewater feeding ports 7, which correspond one-to-one, and the multiple wastewater feeding ports 7 are evenly arranged along the circumference of the atomizing feeder 2.

[0041] In order to further ensure the thorough mixing of wastewater and flocculant, the flocculant atomizing nozzle 5 is located directly below the wastewater feed inlet 7, and the two are in the same vertical plane, so that the flocculant atomizing nozzle 5 and the wastewater feed inlet 7 can be used to the maximum extent.

[0042] For example, the angle between the liquid outlet direction of the flocculant atomizing nozzle 5 and the liquid outlet direction of the wastewater feed port 7, which are located in the vertical direction, is 20° to 60°.

[0043] Understandably, in order to drive the synchronous rotation of the supergravity flocculation inner tank 1, the atomizing dosing device 3 and the atomizing feeder 2, the supergravity flow stabilizing device also includes a drive motor 8 for driving the rotation of the supergravity flocculation inner tank 1, the atomizing dosing device 3 and the atomizing feeder 2.

[0044] It is worth noting that, since the supergravity flocculation inner tank 1, the atomizing dosing device 3, and the atomizing feeder 2 are always in a state of synchronous rotation relative to the stabilizing outer tank, and the three use the same drive motor 8 as a power source, the specific structure and positional relationship of the drive motor 8, the supergravity flocculation inner tank 1, the atomizing dosing device 3, and the atomizing feeder 2 are as follows:

[0045] The atomizing feeder 2 includes a fixed feeding sleeve 21, a rotating feeding sleeve 22, and a support plate 23 arranged sequentially from top to bottom. The top end of the rotating feeding sleeve 22 is sealed and rotatably connected to the bottom end of the fixed feeding sleeve 21. The inner cavity of the fixed feeding sleeve 21 and the inner cavity of the rotating feeding sleeve 22 are not connected. The bottom end of the rotating feeding sleeve 22 penetrates the bottom of the ultra-gravity flocculation inner tank 1 and is sealed and fixedly connected to the bottom of the ultra-gravity flocculation inner tank 1. The support plate 23 is located at the bottom end of the rotating feeding sleeve 22 and has a plate hole. The wastewater feeding arm 6 is located on the side wall of the rotating feeding sleeve 22 and communicates with the inner cavity of the rotating feeding sleeve 22. The side wall of the fixed feeding sleeve 21 has a flocculant inlet 24 to facilitate the supply of flocculant into the inner cavity of the fixed feeding sleeve 21.

[0046] The atomizing dosing device 3 includes a rotating dosing sleeve 31, which passes through the fixed feeding sleeve 21 and is then inserted into the rotating feeding sleeve 22. The rotating dosing sleeve 31 has a flocculant inlet 32 ​​on its side wall inside the fixed sleeve, and a flocculant outlet on its side wall inside the rotating feeding sleeve 22. The flocculant outlet is connected to the flocculant inlet of the flocculant dosing arm 4.

[0047] Accordingly, the drive motor 8 includes a motor shaft 81 and a transmission center shaft 82 fixedly connected to the bottom end of the motor shaft 81. The transmission center shaft 82 passes through the rotary dosing sleeve 31 and the rotary feeding sleeve 22 in sequence and is fixedly connected to the support plate 23. The top end of the rotary dosing sleeve 31, the bottom end of the rotary dosing sleeve 31 and the support plate 23 are all sealed and fixedly connected to the outer wall of the transmission center shaft 82.

[0048] In order to achieve a sealed connection between the various components and prevent leakage, specifically:

[0049] A feeding sealing groove and a feeding sealing protrusion inserted into the feeding sealing groove are provided between the fixed feeding sleeve 21 and the rotating feeding sleeve 22. A feeding sealing ball is provided in the feeding sealing groove. A feeding sealing cavity is formed between the feeding sealing protrusion and the feeding sealing groove. The feeding sealing cavity is filled with sealing fluid (e.g., synthetic machine oil).

[0050] The top inner wall of the fixed feeding sleeve 21 is provided with a first sealing protrusion and a second sealing protrusion. There is a gap between the first sealing protrusion and the second sealing protrusion. The first sealing protrusion, the second sealing protrusion, a part of the outer wall of the rotating dosing sleeve 31 and a part of the outer wall of the fixed feeding sleeve 21 form a top sealing cavity, which is filled with a sealing liquid (e.g., synthetic machine oil).

[0051] Based on the structure of the aforementioned ultragravity flow stabilization device for enhanced flocculation, see [link to relevant documentation]. Figures 2 to 3 The specific working process is as follows:

[0052] When the drive motor 8 is turned on, the motor shaft 81 drives the transmission center shaft 82 to rotate. Correspondingly, the transmission center shaft 82 drives the ultra-gravity flocculation inner tank 1, the atomizing dosing device 3, and the atomizing feeder 2 to rotate simultaneously. Wastewater is supplied from the bottom end of the rotating feed sleeve 22 through the holes in the support plate 23 into the inner cavity of the rotating feed sleeve 22. The wastewater flows upward to the top of the rotating feed sleeve 22, and then, after passing through the wastewater feed arm 6, is sprayed from the wastewater feed port 7 into the ultra-gravity flocculation inner tank 1. The flocculant is supplied into the inner cavity of the fixed feeding sleeve 21 from the flocculant external inlet, and then into the inner cavity of the rotary dosing sleeve 31 from the flocculant internal inlet 32. The flocculant flows downward to the bottom of the rotary dosing sleeve 31, and is then sprayed into the supergravity flocculation inner tank 1 through the flocculant outlet and the flocculant dosing arm 4 and the flocculant atomizing nozzle 5. In the supergravity flocculation inner tank 1, the flocculant and wastewater are subjected to centrifugal force, mix thoroughly, undergo flocculation reaction, and generate sediment, thereby achieving sedimentation and dewatering.

[0053] Example 2

[0054] This embodiment provides a hypergravity flow stabilization device for enhanced flocculation, the structure of which is basically the same as that of the hypergravity flow stabilization device for enhanced flocculation provided in Embodiment 1, the difference being:

[0055] To enhance collision, the aforementioned hypergravity flow stabilization device for enhanced flocculation also includes a dispersion grid 9 disposed on the inner wall of the hypergravity flocculation inner tank 1. (See [reference]) Figure 4 The dispersing grid 9 is set vertically relative to the inner wall of the supergravity flocculation inner tank 1.

[0056] The dispersed grid 9 has multiple layers, and the multiple dispersed grids 9 are evenly arranged in the vertical direction.

[0057] For the structure of the dispersive grid 9, for example, it adopts a detachable structure, including an annular grid and a radial grid. One end of the radial grid is fixedly connected to the supergravity flocculation inner tank 1, and the other end of the radial grid is suspended. The annular grid is disposed on the radial grid and is detachably fixedly connected to the radial grid. The annular grid is coaxially arranged with the supergravity flocculation inner tank 1.

[0058] Thus, on the one hand, during the high-speed rotation of the inner tank 1 of the supergravity flocculation system, the radial grid induces the formation of Karman vortex streets on the rising film on the wall of the inner tank 1. Particles are further amplified and collided within these vortex streets, promoting floc growth. On the other hand, the design of the multi-layer dispersion grid 9 further disperses the wastewater as it falls to the bottom, allowing the atomized flocculant to fully mix with the wastewater passing through it. The wastewater that subsequently passes through the dispersion grid 9 washes away the flocculant mixture, preventing floc adhesion to the walls of the dispersion grid 9.

[0059] To further prevent the dispersing grid 9 from clogging the flocs in the rising film on the inner wall of the supergravity flocculation inner tank 1, the distance between the annular grid on the side closest to the inner wall of the supergravity flocculation inner tank 1 and the inner wall of the supergravity flocculation inner tank 1 is greater than 30 mm (e.g., 30-50 mm), which is greater than the thickness of the maximum film in the supergravity flocculation inner tank 1.

[0060] In order to ensure that the falling wastewater passes through the dispersion grid 9 fully, the length of the flocculant dosing arm 4 in the same vertical plane is less than the length of the wastewater feeding arm 6, so that the falling wastewater flow is scattered again with the flocculant to the dispersion grid 9 under the influence of the cavitation effect at the flocculant atomizing nozzle 5.

[0061] To further promote thorough mixing between wastewater and flocculant and increase the collision frequency between them, the aforementioned hypergravity flow stabilization device for enhanced flocculation also includes multiple wedge-shaped rings 10 located at the bottom of the hypergravity flocculation inner tank 1. These wedge-shaped rings 10 are evenly arranged vertically and coaxially with the hypergravity flocculation inner tank 1. Thus, through the arrangement of these multiple wedge-shaped rings 10, during the high-speed rotation of the hypergravity flocculation inner tank 1, the wedge-shaped rings 10 induce turbulent micro-vortices in the mixed wastewater and flocculant rising along the wall. Under the action of these turbulent micro-vortices, the wastewater and flocculant are thoroughly stirred, increasing the collision frequency between particles and between particles and flocculant molecules in the wastewater.

[0062] For the structure of the supergravity flocculation inner tank 1, for example, it includes a plurality of flocculation sections connected in sequence, and from bottom to top, the angle between the inner wall of the plurality of flocculation sections and the horizontal direction gradually increases.

[0063] In this way, on the one hand, the inner wall of the supergravity flocculation inner tank 1 can buffer the wastewater, and on the other hand, the inner wall of the supergravity flocculation inner tank 1 can promote the rise of the wastewater along the supergravity flocculation inner tank 1, while ensuring that the wastewater has sufficient flocculation time in the supergravity flocculation inner tank 1.

[0064] For example, the wedge-shaped ring 10 is located below the dispersing grid 9. This positional relationship, with its top-to-bottom flow sequence (dispersing grid 9 → wedge-shaped ring 10 → climbing the barrel wall), conforms to the natural laws of particle settling and swirling motion in a hypergravity field. The wastewater flow path is smoother, preventing wastewater from accumulating below the grid and improving equipment operating efficiency.

[0065] On the one hand, it enables staged mixing of wastewater and flocculant. The dispersing grid 9 prioritizes the initial mixing of wastewater and flocculant, while the wedge-shaped ring 10 further refines the mixing, protecting floc growth and reducing the occurrence of floc breakage caused by strong turbulence in a single operation. On the other hand, using the dispersing grid 9 to initially disperse wastewater and flocculant reduces the stirring intensity required by the subsequent wedge-shaped ring 10.

[0066] It should be noted that if the dispersing grid 9 is below the wedge-shaped ring 10, the high-speed rotating wedge-shaped ring 10 will first generate violent eddies, causing the fluid to collide disorderly with the dispersing grid 9, affecting the uniform dispersion effect of the dispersing grid 9, causing the already formed flocs to be torn apart, destroying the bond between the flocculant and the particles, resulting in loose flocs. In addition, if the dispersing grid 9 is below the wedge-shaped ring 10, the eddies generated by the wedge-shaped ring 10 may push the flocs to the dispersing grid 9, causing blockage, requiring frequent cleaning, and affecting continuous operation.

[0067] Based on the above structure, the flow process of wastewater and flocculant is a three-stage enhanced mixing process (atomization dispersion → dispersing grid 9 cutting → wedge-shaped ring 10 micro-vortex), the specific process is as follows:

[0068] Initial dispersion stage: Wastewater is dispersed and sprayed through wastewater feed port 7, and flocculant is atomized into small droplets through flocculant atomizing nozzle 5. Both fall synchronously from top to bottom in the super gravity flocculation inner tank 1.

[0069] The dispersing grid 9 is in the following stages: wastewater and flocculant first pass through the dispersing grid 9. The annular grid and radial grid cut the fluid into multiple thin streams, forming turbulence and vortex streets, which promote the initial collision and mixing of particles and flocculants. Some of the mixture slides along the dispersing grid 9 to the inner wall of the supergravity flocculation inner tank 1, while the rest continues to fall through the gaps in the dispersing grid 9.

[0070] The wedge-shaped ring 10 reinforcement stage: When the fluid reaches the bottom of the wedge-shaped ring 10, the high-speed rotating wedge-shaped ring 10 induces micro-eddies (i.e. turbulence) in the fluid, which agitates the insufficiently mixed wastewater and flocculant a second time. The mixed fluid rises along the inner wall of the supergravity flocculation inner tank 1. When the wastewater rises to the position of the wedge-shaped ring 10, the wedge-shaped ring 10 induces turbulent micro-eddies, which fully mix the wastewater and flocculant under the action of the micro-eddies, increase the collision frequency, and further improve the flocculation effect. The fully mixed wastewater and flocculant finally overflow from the top opening of the supergravity flocculation inner tank 1 to the stable flow outer tank, and finally enter the thickening tank for subsequent treatment.

[0071] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
