Description

Technical Field

[0001] This utility model relates to the field of water purification system technology, and in particular to a reactor for a water purification system. Background Technology

[0002] Raw water refers to water collected from nature, including groundwater, spring water, reservoir water, and other natural water sources, without undergoing any artificial purification treatment. Waterworks collect raw water, purify it to produce tap water that meets national standards, and then deliver it to households to meet people's daily needs.

[0003] Existing water purification systems include reaction tanks for adding chemicals to raw water, sedimentation tanks, filtration tanks, and clear water tanks, all connected by water pipes. This modular layout results in a large overall footprint and requires numerous water pipes, leading to higher costs.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a reactor for a water purification system, which aims to solve the technical problems of the large footprint and numerous water supply pipes required by the split layout of the existing water purification system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reactor for a water purification system includes a tank, a reaction tube coaxially arranged inside the tank, an inlet pipe connected to the lower end of the reaction tube, a vortex tube connected to the upper end of the reaction tube, the vortex tube connecting the reaction tube to the inside of the tank and forming a vortex after the water flows through the vortex tube, a grid plate is provided in the middle of the tank outside the reaction tube, and an outlet pipe is connected to the lower end of the tank.

[0008] The reactor of the water purification system has the upper and lower ends of the reaction tube fixedly connected to the top and bottom of the tank, respectively. An annular reaction zone and a clear water zone are formed between the inner wall of the tank and the outer wall of the reaction tube. The reaction zone and the clear water zone are separated by a grid plate.

[0009] The reactor of the water purification system includes at least two cyclone tubes, which are evenly arranged around the circumference of the reaction tube. The cyclone tubes are located in the reaction zone, and the water outlet direction of the cyclone tubes is consistent with the tangential direction of the inner wall of the tank.

[0010] In the reactor of the water purification system, the end of the cyclone tube away from the reaction tube is an arc-shaped tube, and the tangent extensions of multiple arc-shaped tubes form a complete circumference.

[0011] The reactor of the water purification system has an inlet pipe that penetrates the side wall of the tank and is connected to the side wall of the reaction tube. The end of the inlet pipe located outside the tank is connected to an aeration pipe.

[0012] The reactor of the water purification system is described above. The grid plate is formed by stacking multiple grid layers from the reaction zone to the clear water zone. Each grid layer is provided with several grid holes. The several grid holes on the same grid layer have the same hole diameter, and the hole diameter of the grid holes in different grid layers gradually decreases along the water flow direction.

[0013] The reactor of the water purification system has a grid hole shape that is polygonal or circular, and the grid holes of adjacent grid layers are staggered.

[0014] Beneficial effects:

[0015] This invention provides a reactor for a water purification system, including a tank containing a reaction tube and a grid plate. The lower end of the reaction tube is connected to an inlet pipe, and the upper end of the reaction tube is connected to the tank via a vortex tube. The grid plate is fitted around the middle of the reaction tube. Raw water with added coagulant enters the bottom of the reaction tube through the inlet pipe. As the raw water rises within the reaction tube, the coagulant mixes thoroughly with suspended solids in the water to form flocs. The water carrying the flocs flows into the tank through the vortex tube, creating a rotating flow. The vortex reaction caused by the rotating flow causes the flocs to collide and aggregate. The water then flows downwards through the grid plate, where a grid reaction occurs, filtering the flocs to obtain clean water that flows downwards. Finally, the clean water is output through the outlet pipe. This water purification system integrates the chemical dosing reaction and filtration steps into a single tank, saving the overall floor space of the water purification system. The reaction zone and the clean water zone are directly connected by the grid plate, saving the cost of laying long water pipes. Attached Figure Description

[0024] This utility model provides a reactor for a water purification system. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0026] Please see Figures 1 to 2As shown, this utility model provides a reactor for a water purification system, including a tank 1. A reaction tube 2 is coaxially arranged inside the tank 1. The lower end of the reaction tube 2 is connected to an inlet pipe 3, and the upper end of the reaction tube 2 is connected to a vortex tube 4. The vortex tube 4 connects the reaction tube 2 to the inside of the tank 1, and the water flow forms a vortex after passing through the vortex tube 4. A grid plate 5 is provided in the middle of the tank 1, fitted outside the reaction tube 2. The lower end of the tank 1 is connected to an outlet pipe 6. In this embodiment, the tank 1 can be a cylindrical tank 1. The upper end of the reaction tube 2 is sealed to the top of the tank 1, and the lower end of the reaction tube 2 is sealed to the bottom of the tank 1. The tank 1 and the reaction tube 2 are connected only by the vortex tube 4. The inlet pipe 3 penetrates the side wall of the tank 1, and the connection between the outer wall of the inlet pipe 3 and the side wall of the tank 1 is sealed. The height of the inlet pipe 3 is greater than the height of the outlet pipe 6. The grid plate 5 is located between the vortex tube 4 and the outlet pipe 6. In the water purification process, raw water with added coagulant enters the bottom of the reaction tube 2 through the inlet pipe 3. As the raw water rises in the reaction tube 2, the coagulant mixes thoroughly with the suspended solids in the water to form flocs. The water carrying the flocs flows into the tank 1 through the vortex pipe 4, forming a rotating water flow. The vortex reaction caused by the rotating water flow causes the flocs to collide and aggregate. Then, the water flows downward through the grid plate 5, where a grid reaction occurs, filtering the flocs and obtaining clear water that flows downward. Finally, the clear water is output through the outlet pipe 6. The reactor of this water purification system integrates the chemical dosing reaction and filtration steps into a single tank 1, saving the overall footprint of the water purification system. The reaction zone 11 and the clear water zone 12 are directly connected by the grid plate 5, saving the cost of laying long water pipes and reducing the risk of this section of the water pipe being blocked by flocs.

[0027] Please see Figure 1 As shown, the upper and lower ends of the reaction pipe 2 are fixedly connected to the top and bottom of the tank body 1, respectively. An annular reaction zone 11 and a clear water zone 12 are formed between the inner wall of the tank body 1 and the outer wall of the reaction pipe 2. The reaction zone 11 and the clear water zone 12 are separated by a mesh plate 5. In this embodiment, the connection between the reaction pipe 2 and the tank body 1 can be achieved through welding. A sludge discharge port is provided on the side wall of the tank body 1, equipped with a sludge discharge valve. The sludge discharge port is located near the lower part of the reaction zone 11. The water outlet pipe 6 is located at the lower end of the clear water zone 12 and is equipped with a control valve. Water containing flocculants flows from the reaction zone 11 to the clear water zone 12. The flocculants are filtered by the mesh plate 5 and remain on the mesh plate 5 in the reaction zone 11, thus obtaining clear water that flows to the clear water zone 12 and is discharged to other equipment outside the tank body 1 through the water outlet pipe 6.

[0028] Please see Figures 1 to 2As shown, there are at least two cyclone tubes 4, which are evenly arranged around the reaction tube 2. The cyclone tubes 4 are located in the reaction zone 11, and the water outlet direction of the cyclone tubes 4 is consistent with the tangential direction of the inner wall of the tank 1. The end of the cyclone tube 4 away from the reaction tube 2 is an arc-shaped tube 41, and the tangent extensions of the multiple arc-shaped tubes 41 form a complete circumference. In this embodiment, there are two cyclone tubes 4, which are symmetrically arranged with the axis of the reaction tube 2 as the point. The two cyclone tubes 4 are at the same height and located in the upper part of the reaction zone 11. The water flow from the reaction tube 2 through the cyclone tubes 4 and out of the reaction zone 11 will form a water flow rotating around the reaction tube 2 to enhance the collision and aggregation of flocculants in the water flow.

[0029] Please see Figure 1 As shown, the inlet pipe 3 penetrates the side wall of the tank 1 and connects to the side wall of the reaction pipe 2. One end of the inlet pipe 3, located outside the tank 1, is connected to an aeration pipe 31. In this embodiment, the inlet pipe 3 is generally L-shaped. One end of the inlet pipe 3 horizontally passes through the side wall of the tank 1 and the side wall of the reaction pipe 2, while the other end extends vertically to the bottom of the reaction pipe 2, allowing the raw water containing coagulant to first enter the bottom of the reaction pipe 2. The aeration pipe 31, connected to the wall of the inlet pipe 3, injects microbubbles into the raw water, causing an aeration reaction within the reaction pipe 2 and promoting rapid mixing of the coagulant and suspended solids to form flocs. The inlet pipe 3 can also be equipped with a one-way valve to prevent backflow.

[0030] Please see Figure 1 and Figure 3 As shown, the mesh plate 5 is formed by stacking multiple mesh layers 51 from the reaction zone 11 to the clear water zone 12. Each mesh layer 51 is provided with several mesh holes 52. The mesh holes 52 on the same mesh layer 51 have the same pore size, while the pore size of the mesh holes 52 in different mesh layers 51 gradually decreases along the water flow direction. In this embodiment, the mesh plate 5 may be composed of three layers of polypropylene mesh layers 51 stacked together. The pore sizes of the three mesh layers 51 from the reaction zone 11 to the clear water zone 12 are respectively large pore size, medium pore size, and small pore size, thus performing graded filtration and improving the filtration effect.

[0031] Please see Figure 3 As shown, the mesh holes 52 are polygonal or circular in shape, and the mesh holes 52 of adjacent mesh layers 51 are staggered to enhance water flow turbulence.

[0032] In summary, this utility model integrates the chemical dosing reaction and filtration steps into one tank 1 by setting the reaction tube 2 inside the tank 1, thus saving the overall floor space of the water purification system. The reaction zone 11 and the clear water zone 12 are directly connected by the grid plate 5, saving the cost of laying long water pipes and reducing the risk of this section of water pipe being blocked by flocculents. The cyclone tube 4 and the grid plate 5 work together to shorten the flocculation filtration time and improve the water purification efficiency.

[0033] It is understood that those skilled in the art can make equivalent substitutions or modifications based on the technical solution and inventive concept of this utility model, and all such substitutions or modifications should fall within the protection scope of the appended claims of this utility model.
