Description

Technical Field

[0001] This utility model relates to the field of water purification and filtration, and in particular to a high-efficiency vortex sedimentation flocculation reaction tank. Background Technology

[0002] Flocculation refers to the process by which suspended particles in water or liquid aggregate and become larger, or form flocs, thereby accelerating particle settling and achieving solid-liquid separation. This phenomenon or operation is called flocculation. Flocculation is usually achieved by adding appropriate flocculants, whose role is to adsorb particles and "bridge" between them, thus promoting aggregation.

[0003] Existing flocculation processes mostly use square box structures as reaction tanks. Due to space limitations, flocculation tanks cannot be laid in some scenarios. At the same time, the square box structure is inconsistent with the normal water flow direction, which will lead to a large head loss, affecting the flocculation effect and reducing flocculation efficiency. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to propose a high-efficiency vortex sedimentation flocculation reaction tank.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides a high-efficiency cyclone sedimentation flocculation reactor, including a first pipeline, a first sleeve, a first cover plate, a collecting trough, a second sleeve, a second pipeline, a first discharge pipe, and a guide plate assembly. The first pipeline has a first end and a second end, with the first end lower than the second end. The first end is used to connect to raw water, and the second end is used to discharge raw water. The upper part of the first sleeve has a second end, which communicates with the first sleeve along the tangential direction of the first sleeve. The first cover plate is located at the top of the first sleeve, and the second end is located close to the first cover plate. The collecting trough is located at the bottom of the first sleeve, and the collecting trough is conical and sealed to the first sleeve. The second sleeve is located inside the first sleeve, and is coaxial with the first sleeve. The top of the second sleeve is sealed to the first cover plate, and the bottom of the second sleeve communicates with the first sleeve. One end of the second pipeline communicates with the second sleeve along the tangential direction of the second sleeve, and the other end of the second pipeline protrudes out of the first sleeve and communicates with external equipment.

[0007] The first drain pipe is located at the bottom of the collecting tank; the area between the first sleeve and the second sleeve is the first chamber, the inner side of the second sleeve is the second chamber, the area of ​​the collecting tank is the collecting chamber, and the first chamber and the second chamber are connected through the collecting chamber; the guide plate assembly is located in the second chamber, and the height of the guide plate assembly is lower than that of the second pipe. The guide plate assembly is used to guide the water flow in the second chamber.

[0008] In some embodiments, the first drain pipe has a first central axis and the collecting trough has a second central axis; the first central axis is perpendicular to the second central axis; or, the first central axis coincides with the second central axis.

[0009] In some embodiments, the guide plate assembly includes a plurality of first guide plates, which are arranged in parallel within the second chamber. There is a gap between two adjacent first guide plates to allow water to flow through. The first guide plates are inclined at a certain angle to the second sleeve.

[0010] In some embodiments, the guide plate assembly further includes a plurality of second guide plates, which are arranged in parallel within the second chamber. There is a gap between two adjacent second guide plates to allow water to flow through. Each second guide plate intersects with a plurality of first guide plates, and the second guide plates are inclined at a certain angle to the second sleeve.

[0011] In some embodiments, a static mixer is provided at the second end for mixing the coagulant with the raw water.

[0012] In some embodiments, a grid group is also included, disposed within a first chamber, the grid group comprising at least one grid for mixing the raw water with the coagulant.

[0013] In some embodiments, there are multiple grids, which extend vertically and are spaced apart circumferentially around the periphery of the second sleeve.

[0014] In some embodiments, the mesh extends in a spiral shape within the first chamber.

[0015] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0016] Unlike existing technologies, the high-efficiency cyclone sedimentation flocculation reactor described above includes a first pipeline, a first sleeve, a first cover plate, a collecting trough, a second sleeve, a second pipeline, a first drain pipe, and a guide plate assembly. The first and second sleeves are coaxially arranged, and the collecting trough is located below the first sleeve. In operation, water flows through the first pipeline into the first chamber between the first and second sleeves. Due to inertia, the water flow generates swirling and eddy currents, promoting flocculation and impurity settling. The settled sand and impurities settle in the collecting chamber under gravity and are finally discharged through the first drain pipe. Meanwhile, the upper purified water enters the second chamber within the second sleeve during the swirling process and moves upward under the pressure of the settled sand and gravel, ultimately being output through the second pipeline above the second sleeve. Compared to traditional sedimentation tanks, this device significantly improves water treatment efficiency, flocculation effect, and impurity removal rate through its swirling design, multi-chamber structure, and guide plate guidance. It features a compact structure, stable operation, and strong treatment capacity, and can be widely used in water supply treatment, sewage treatment, and other fields, which is of great significance for improving water quality.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0040] Please see Figures 1 to 4This embodiment provides a high-efficiency cyclone sedimentation flocculation reactor, including a first pipeline 3, a first sleeve 1, a first cover plate 9, a collecting trough 5, a second sleeve 2, a second pipeline 4, a first drain pipe 6, and a guide plate assembly 7. The first pipeline 3 has a first end 31 and a second end 32, with the first end 31 lower than the second end 32. The first end 31 is used to connect to raw water, and the second end 32 is used to output raw water. The upper part of the first sleeve 1 is provided with the second end 32, and the second end 32 communicates with the first sleeve 1 along the tangential direction of the first sleeve 1. The first cover plate 9 is located at the top of the first sleeve 1, and the second end 32 is located close to the first cover plate 9. The collecting trough 5 is located at the bottom of the first sleeve 1, and the collecting trough 5 is conical and sealed to the first sleeve 1. The second sleeve 2 is located at the bottom of the first sleeve 1. Inside a sleeve 1, a second sleeve 2 is coaxially arranged with the first sleeve 1. The top of the second sleeve 2 is sealed to the first cover plate 9, and the bottom of the second sleeve 2 is connected to the first sleeve 1. One end of the second pipe 4 is connected to the second sleeve 2 along the tangent direction of the second sleeve 2, and the other end of the second pipe 4 protrudes out of the first sleeve 1 and is connected to external equipment. The first drain pipe 6 is located at the bottom of the collecting tank 5. The area between the first sleeve 1 and the second sleeve 2 is the first chamber 11, the inner side of the second sleeve 2 is the second chamber 21, and the area of ​​the collecting tank 5 is the collecting chamber 51. The first chamber 11 and the second chamber 21 are connected through the collecting chamber 51. The guide plate group 7 is located in the second chamber 21. The height of the guide plate group 7 is lower than that of the second pipe 4. The guide plate group 7 is used to guide the water flow in the second chamber 21.

[0041] The first pipe 3 is the inlet pipe for raw water to enter the reaction tank. The first end 31 is lower than the second end 32, adopting a bottom-in, top-out configuration to facilitate the subsequent water flow to swirl within the first chamber 11 under the influence of gravitational potential energy. Optionally, a booster pump can be installed on the first pipe 3 to achieve the above effect. The first sleeve 1 is a thin-shell-shaped outer cylinder. The upper part of the first sleeve 1 is connected to the second end 32, and the second end 32 is positioned along the tangential direction of the first sleeve 1. This further facilitates the water flow entering the first chamber 11 and directly starting to swirl along the inner wall of the first sleeve 1, reducing head loss. The first cover plate 9 covers the top of the first sleeve 1, and the second end 32 is positioned close to the area where the first cover plate 9 is located. Specifically, it can be combined with... Figure 1 and Figure 2 To understand.

[0042] The collecting trough 5 is a thin-walled structure located at the bottom of the first sleeve 1. The collecting trough 5 has a conical shape and is used to collect sediment. The conical surface of the collecting trough 5 can form a complete unit with the first sleeve 1; in some optional embodiments, the collecting trough 5 and the first sleeve 1 are integrally formed. The second sleeve 2 is disposed inside the first sleeve 1, and the second sleeve 2 is coaxially arranged with the first sleeve 1. The top of the second sleeve 2 is sealed to the first cover plate 9, and the bottom communicates with the first sleeve 1. Figure 1 as well as Figure 2 As shown, the first sleeve 1 and the second sleeve 2 are not connected in the area where the first cover plate 9 is located. The water flow in the first pipe 3 first swirls in the first chamber 11. After reaching the bottom under the action of gravity, the water flow cross-section is suddenly reduced due to the setting of the collecting tank 5. At the same time, under the obstruction of the settled impurities, the water flow will spiral upward along the center to enter the second sleeve 2 and flow out through the second pipe 4 on the second sleeve 2. The first drain pipe 6 is set at the bottom of the collecting tank 5 to discharge the settled impurities and sand particles. The guide plate assembly 7 is set in the second chamber 21. The guide plate assembly 7 includes multiple guide plates and is lower than the second pipe 4. The guide plate assembly 7 can further block the residual impurities in the second sleeve 2. At the same time, the guide plate assembly 7 can guide the water flow to flow towards the second pipe 4.

[0043] In some optional embodiments, the guide plates of the guide plate assembly 7 can be spirally coiled inside the second sleeve 2 to match the direction of water flow and reduce potential energy loss during water flow.

[0044] This embodiment includes a first pipe 3, a first sleeve 1, a first cover plate 9, a collecting trough 5, a second sleeve 2, a second pipe 4, a first drain pipe 6, and a guide plate assembly 7. The first sleeve 1 and the second sleeve 2 are coaxially arranged, and the collecting trough 5 is located below the first sleeve 1. In use, water flows through the first pipe 3 into the first chamber 11 between the first sleeve 1 and the second sleeve 2. Under the action of inertia, the water flow generates swirling and eddy currents, which promote flocculation and sedimentation of impurities. The precipitated sand and impurities settle in the collecting chamber 51 under the action of gravity and are finally discharged through the first drain pipe 6. Meanwhile, the upper purified water enters the second chamber 21 inside the second sleeve 2 during the swirling process and moves upward under the push of the settled sand and gravel, and is finally output through the second pipe 4 above the second sleeve 2. Compared to traditional sedimentation tanks, this device significantly improves water treatment efficiency, flocculation effect, and impurity removal rate through its swirling design, multi-chamber structure, and guide plate guidance. It features a compact structure, stable operation, and strong treatment capacity, and can be widely used in water supply treatment, sewage treatment, and other fields, which is of great significance for improving water quality.

[0045] In some embodiments, the first drain pipe 6 has a first central axis and the collecting trough 5 has a second central axis; the first central axis is perpendicular to the second central axis; or, the first central axis coincides with the second central axis.

[0046] It is understandable that the first central axis and the second central axis are used as reference lines. When the first central axis and the second central axis are perpendicular, it can be understood that the first sewage pipe 6 is set on the side wall of the collecting tank 5, and the first sewage pipe 6 is set in the horizontal direction. Figure 1As shown; when the first central axis coincides with the second central axis, it indicates that the first sewage pipe 6 is set at the bottom of the conical structure of the collecting tank 5, and the first sewage pipe 6 is set in the vertical direction.

[0047] This embodiment provides two distribution methods for the first sewage pipe 6 on the collecting tank 5, which can be adjusted according to actual needs to achieve the best sewage discharge efficiency of the first sewage pipe 6.

[0048] Please see Figure 3 and Figure 4 In some embodiments, the guide plate assembly 7 includes a plurality of first guide plates 71, which are arranged in parallel within the second chamber 21. A gap exists between adjacent first guide plates 71 to allow water flow. The first guide plates 71 are inclined at a certain angle to the second sleeve 2. The first guide plates 71 can further block residual impurities within the second sleeve 2, and simultaneously guide the water flow towards the second pipeline 4.

[0049] For further details, please refer to Figure 3 and Figure 4 In some embodiments, the guide plate assembly 7 further includes a plurality of second guide plates 72, which are arranged in parallel within the second chamber 21. A gap exists between adjacent second guide plates 72 to allow water flow. Each second guide plate 72 intersects with a plurality of first guide plates 71, and the second guide plates 72 are inclined at a certain angle to the second sleeve 2. The intersecting arrangement of the first guide plates 71 and second guide plates 72 increases the contact area between the water flow and the first and second guide plates 71 and 72. The first and second guide plates 71 and 72 can further block the rise of impurities, thereby improving the purity of the water flow at the second pipeline 4.

[0050] In some embodiments, a static mixer is provided at the second end 32 for mixing the coagulant and the raw water. The static mixer is a device that achieves fluid mixing without external power; it mainly consists of a series of fixed mixing elements, and achieves efficient mixing of the fluid through the flow and interaction of the fluid within these elements. The static mixer at the second end 32 allows for thorough mixing of the coagulant pre-added to the raw water with the raw water, facilitating improved subsequent flocculation efficiency.

[0051] Please see Figure 2 and Figure 3 In some embodiments, a grid group 8 is also included, disposed within the first chamber 11. The grid group 8 includes at least one grid 8, which is used to mix the raw water with the coagulant. In this embodiment, the grid group 8 can be positioned according to actual needs.

[0052] Specifically, in some embodiments, there are multiple grids 8, which extend vertically and are spaced apart circumferentially around the periphery of the second sleeve 2. For example... Figure 3 As shown, multiple grids 8 are distributed vertically. During the swirling process, the water flow will pass through multiple grids 8 in sequence. The interaction between these static grids 8 and the dynamic water flow allows the coagulant to be mixed more thoroughly with the water flow, thereby achieving a stirring effect on the water flow and improving flocculation efficiency.

[0053] Furthermore, in some embodiments, the mesh 8 extends in a spiral shape within the first chamber 11. For example... Figure 2 As shown, Figure 2 The dashed line shown is a schematic path of grid 8 extending in a spiral. In this process, grid 8 can guide the water flow while mixing the coagulant in the water flow, which is more in line with the actual state of water vortex and reduces the head loss of the water flow.

[0054] Unlike existing technologies, the high-efficiency vortex sedimentation flocculation reactor in the above technical solution includes a first pipe 3, a first sleeve 1, a first cover plate 9, a collecting trough 5, a second sleeve 2, a second pipe 4, a first drain pipe 6, and a guide plate assembly 7. The first sleeve 1 and the second sleeve 2 are coaxially arranged, and the collecting trough 5 is located below the first sleeve 1. In use, water flows through the first pipe 3 into the first chamber 11 between the first sleeve 1 and the second sleeve 2. Under the action of inertia, the water flow generates vortex and eddy currents, which promote flocculation reaction and sedimentation of impurities. The precipitated sand particles and impurities settle in the collecting chamber 51 under the action of gravity and are finally discharged through the first drain pipe 6. Meanwhile, the upper purified water enters the second chamber 21 inside the second sleeve 2 during the vortex process and moves upward under the push of the settled sand and gravel, and is finally output through the second pipe 4 above the second sleeve 2. Compared to traditional sedimentation tanks, this device significantly improves water treatment efficiency, flocculation effect, and impurity removal rate through its swirling design, multi-chamber structure, and guide plate guidance. It features a compact structure, stable operation, and strong treatment capacity, and can be widely used in water supply treatment, sewage treatment, and other fields, which is of great significance for improving water quality.
