Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment equipment, specifically to a high-efficiency vortex reactor. Background Technology

[0002] High-efficiency vortex reactors, as a type of wastewater treatment equipment, can effectively remove pollutants such as organic matter, inorganic matter, and heavy metal ions from wastewater, enabling the wastewater to meet discharge standards. During wastewater treatment, high-efficiency vortex reactors use coagulants and flocculants to cause suspended solids, colloidal substances, and other pollutants in the wastewater to form flocs that float to the surface, thus achieving pollutant removal. However, in traditional high-efficiency vortex reactors, the coagulants and flocculants cannot be mixed thoroughly with the wastewater in a timely manner after addition, easily leading to waste of reagents and poor pollutant removal efficiency. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a high-efficiency vortex reactor.

[0004] To achieve the above objectives, the technical solution adopted by this utility model includes: a tank body, an inlet pipe having a first pipe and a second pipe interconnected, the first pipe connecting to the outside of the tank body, and the second pipe extending to the lower part of the inside of the tank body; at least one dosing channel connecting to the second pipe; and a cross-flow dispersion structure, including at least a plurality of cross-flow baffles, the plurality of cross-flow baffles being arranged along the height direction in the second pipe, wherein the wastewater flowing in the second pipe body and the reagent are dispersed and mixed by means of the plurality of cross-flow baffles.

[0005] This application involves configuring several cross-flow baffles arranged along the height direction in the second pipe of the inlet pipe, so that the mixture of wastewater and reagent entering the second pipe can be fully dispersed and mixed, thereby improving the mixing degree of coagulant, flocculant and wastewater, and improving the aggregation effect on particulate matter and colloidal matter in wastewater.

[0006] In the preferred embodiment of the above-mentioned high-efficiency vortex reactor, a liquid vortex generator is provided inside the tank. When the mixture of wastewater and reagent is discharged into the tank through the second pipeline, the liquid vortex generator can agitate the mixture to form a micro vortex inside the tank.

[0007] In the preferred embodiment of the above-mentioned high-efficiency vortex reactor, the liquid vortex generating element is a flocculation packing ball.

[0008] In the preferred embodiment of the above-mentioned high-efficiency vortex reactor, a perforated plate is disposed between the inner wall of the bottom of the tank and the second pipeline of the water inlet pipe, and the liquid vortex generator is disposed on the perforated plate.

[0009] In the preferred embodiment of the above-mentioned high-efficiency vortex reactor, at least two crossflow baffles are configured at the same height within the second pipeline.

[0010] In the preferred embodiment of the above-mentioned high-efficiency vortex reactor, there are two dosing channels, namely a first dosing pipe and a second dosing pipe that are sequentially connected to the second pipeline of the inlet pipe along the height direction.

[0011] In the preferred embodiment of the above-mentioned high-efficiency vortex reactor, a baffle plate is arranged on the bottom surface of the tank directly below the second inlet pipe. The baffle plate forms a baffle section on the side facing the second pipe, which can guide the liquid flowing out of the second pipe toward the top of the tank.

[0012] In the preferred embodiment of the above-mentioned high-efficiency vortex reactor, the top of the tank has a feeding port.

[0022] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] It should be noted that in the description of this utility model, terms such as "upper," "lower," "left," "right," "front," and "rear," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figures 1 to 5 As shown, the high-efficiency vortex reactor of this utility model includes: a tank 1; an inlet pipe 2 with a first pipe 21 and a second pipe 22 connected to each other; the first pipe 21 connects to the outside of the tank 1, and the second pipe 22 extends to the lower part of the inside of the tank 1; at least one dosing channel 3 connected to the second pipe 22; and a cross-flow dispersion structure, including at least a plurality of cross-flow baffles 4, which are arranged along the height direction in the second pipe 22, and the wastewater flowing in the second pipe 22 and the reagent are dispersed and mixed by means of the plurality of cross-flow baffles 4.

[0026] See Figure 1 , Figure 3 The first pipe 21 of the inlet pipe 2 is located on the side of the tank 1, and the second pipe 22 of the inlet pipe 2 is vertically located inside the tank 1 and is located in the middle of the tank 1. The bottom end of the second pipe 22 can extend to the lower part of the tank 1 to communicate with the internal space of the tank 1. The first pipe 21 and the second pipe 22 are connected. Wastewater can enter through the first pipe 21 of the inlet pipe 2 and be discharged into the tank 1 through the second pipe 22.

[0027] See Figures 1 to 3The dosing channel 3 is located on the side wall of tank 1 and on the second pipeline 22 of inlet pipe 2. The dosing channel 3 is used to add coagulant or flocculant into the second pipeline 22. The coagulant can coagulate suspended solids, colloidal particles, and other substances in wastewater into larger particles, while the flocculant is used to further aggregate the coagulated particles to form even larger flocs or clumps. It should be noted that the coagulant must be added to the second pipeline 22 before the flocculant.

[0028] See Figure 3 , Figure 4 The cross-flow dispersion structure includes at least several cross-flow baffles 4. The cross-flow baffles 4 are plate-shaped and can be fan-shaped, circular, or other possible structures capable of guiding liquid flow. The cross-flow baffles 4 are sequentially arranged along the height direction within the second pipe 22 of the inlet pipe 2. The cross-flow baffles 4 at different heights are all arranged at an angle, thereby achieving thorough mixing of wastewater and reagents while accelerating the flow velocity of the liquid within the second pipe 22. In other possible embodiments, the cross-flow baffles 4 at different heights are horizontally deflected around the central axis of the second pipe 22, resulting in several cross-flow baffles 4 having different orientations, further enhancing the effect of dispersing and mixing the fluid within the second pipe 22.

[0029] Specifically, when treating wastewater, the wastewater enters through the first pipe 21 of the inlet pipe 2. At the same time, a coagulant can be added into the first pipe 21. The coagulant will agglomerate suspended solids and colloidal particles in the wastewater into small particles. When the wastewater flows into the second pipe 22, a flocculant can be added through the dosing channel 3. The flocculant will further agglomerate the small particles to form flocs or flocs. In addition, when the mixture of wastewater and chemicals passes through the second passage of the inlet pipe 2, the mixture can flow through a number of cross-flow baffles 4 arranged sequentially along the height direction. The cross-flow baffles 4 can further disperse the mixture, thereby improving the mixing degree of the coagulant, flocculant and wastewater, and improving the aggregation effect of this application on particulate matter and colloidal matter in wastewater.

[0030] In one or more embodiments, a liquid vortex generator is provided inside the tank 1. When the mixture of wastewater and reagent is discharged into the tank 1 through the second pipeline 22, the liquid vortex generator can agitate the mixture to form a micro vortex inside the tank 1. The liquid vortex generator is a flocculation packing ball.

[0031] See Figure 3 The flocculation packing balls are hollow, porous spherical objects. When the wastewater and the mixture of chemicals flowing into the lower part of the tank 1 pass through the complex surface of the flocculation packing balls, a number of tiny eddies are generated. The eddies can break the stable state of suspended particles and colloidal substances in the mixture, accelerate the collision and combination between tiny particles, and thus further accelerate the formation of flocs.

[0032] In one or more embodiments, a perforated plate 5 is disposed between the inner wall of the bottom of the tank 1 and the second pipe 22 of the water inlet pipe 2, and a liquid vortex generator is disposed on the perforated plate 5.

[0033] See Figure 3 The perforated plate 5 is annular. The perforated plate 5 allows the liquid at the bottom of the tank 1 to flow out to the top of the perforated plate 5. At the same time, the multiple flocculation packing balls placed on the top of the perforated plate 5 can accelerate the formation of flocs and float to the liquid surface, thereby removing pollutants from the wastewater. In addition, this design facilitates centralized management and removal of the flocculation packing balls. Furthermore, it can prevent the flocculation packing balls from entering the second pipe 22 of the inlet pipe 2, reducing the frequency of equipment maintenance.

[0034] In one or more embodiments, at least two crossflow baffles 4 are disposed at the same height within the second conduit 22. See also Figure 3 , Figure 4 At the same height within the second pipe 22, when two cross-flow baffles 4 are configured, the two cross-flow baffles 4 are offset around the central axis of the second pipe 22, forming two passageways for fluid to pass through between the two cross-flow baffles 4 and the second pipe 22. This configuration can further improve the subdivision of the fluid within the second pipe 22 and enhance the mixing degree of the reagent and wastewater.

[0035] In one or more embodiments, the dosing channel 3 has two parts, namely a first dosing pipe 31 and a second dosing pipe 32 that are sequentially connected to the second pipeline 22 of the water inlet pipe 2 along the height direction.

[0036] See Figure 3 , Figure 4 The first dosing pipe 31 is positioned above the second dosing pipe 32. The first dosing pipe 31 is used to add coagulant, and the second dosing pipe 32 is used to add flocculant. By configuring two independent first dosing pipes 31 and second dosing pipes 32, the coagulant is added into the second pipe 22 before the flocculant, ensuring the formation effect of flocs in the wastewater in the tank 1. At the same time, this setting allows for precise control of the amount of coagulant and flocculant added.

[0037] In one or more embodiments, a baffle plate 6 is disposed on the bottom surface inside the tank body 1 directly below the second pipe 22 of the water inlet pipe 2. The baffle plate 6 has a baffle section 61 on the side facing the second pipe 22 that can guide the liquid flowing out of the second pipe 22 toward the top of the tank body 1.

[0038] See Figure 3 , Figure 5The tank body 1 has a drain outlet at the bottom. The baffle plate 6 is located directly below the drain outlet and directly below the bottom opening of the second pipeline 22. The baffle plate 6 does not block the drain outlet. The baffle section 61 at the top of the baffle plate 6 has an umbrella-shaped structure. When the mixture of wastewater and reagent flows out of the second pipeline 22 into the tank body 1, the mixture will flow directly onto the baffle section 61 of the baffle plate 6. The umbrella-shaped baffle section 61 buffers and guides the mixture, ensuring that the mixture flows stably towards the porous plate 5. This reduces the impact of the mixture on the bottom of the tank body 1, which would cause the tank body 1 to vibrate. It also reduces the generation of bubbles in the mixture and accelerates the formation of flocs.

[0039] In one or more embodiments, the tank 1 has a feeding port 11 at the top. See also Figure 1 , Figure 2 The feeding port 11 is used to feed materials into the tank 1. The materials can be flocculated filler balls or other substances.

[0040] In one or more embodiments, a manhole 12 is provided on the lower side of the tank body 1. See also Figure 1 , Figure 2 The manhole 12 is located above the perforated plate 5. The manhole 12 facilitates the maintenance and replacement of parts inside the tank 1 by staff and makes it easier to clean the inside of the tank 1.

[0041] In one or more embodiments, the inlet pipe 2 is coated with a polytetrafluoroethylene (PTFE) coating. It should be noted that the PTFE coating has a certain self-lubricating effect, which can reduce the possibility of particles in the wastewater adhering to the inner wall of the inlet pipe 2. In other possible embodiments, the cross-flow baffle 4 is coated with a PTFE coating.

[0042] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
