Description

Technical Field

[0001] This application relates to the field of sludge clarification technology, and in particular to a suspended sludge clarification device. Background Technology

[0002] Suspended sludge clarification devices, as important water treatment equipment, are widely used in municipal water supply, oilfield produced water treatment, and industrial wastewater treatment. Their core function is to utilize a suspended sludge layer to adsorb, flocculate, and precipitate suspended solids, colloids, and some dissolved organic matter in the water, thereby purifying the water. However, existing suspended sludge clarification devices still have some shortcomings in practical applications, affecting their treatment efficiency and operational stability.

[0003] During operation, the stability of the sludge layer in existing suspended sludge clarification devices is often affected by various factors, such as changes in raw water quality, coagulant dosage, and upward flow velocity. Instability in the sludge layer can lead to decreased treatment efficiency and even equipment blockage. Existing suspended sludge clarification devices have relatively complex structures, involving the coordinated operation of multiple components and systems. Therefore, their maintenance and management are challenging, requiring regular inspections, cleaning, and repairs by qualified personnel. Furthermore, the presence of sludge and wastewater media within the equipment poses potential safety hazards during maintenance. In addition, existing suspended sludge clarification devices may experience reduced treatment efficiency or become unsuitable for treating high turbidity, high organic matter content, or complex water qualities. This limits their application effectiveness in certain specific scenarios. Utility Model Content

[0049] Example 1

[0050] like Figure 1 As shown, the suspended sludge clarification device provided in this embodiment includes a main body 1, an inlet pipe 2, an ascending cylinder 3, a reaction chamber 4, a central sludge collection cylinder 5, and an outlet pipe 6;

[0051] One end of the inlet pipe 2 extends from the bottom of the main body 1, and the other end is connected to the bottom of the riser 3 inside the main body 1, for introducing wastewater containing flocculant from the outside into the riser 3;

[0052] The riser 3 is a cylindrical body, and the inlet pipe 2 is connected to the riser 3 along the tangential direction of its side wall, thereby causing the wastewater containing flocculant to form a vortex after entering the riser 3; (e.g.) Figure 3 (As shown)

[0053] The reaction chamber 4 is located at the upper end of the rising cylinder 3, and the diameter of the reaction chamber 4 is not less than the diameter of the rising cylinder 3;

[0054] In the rising cylinder 3 and the reaction chamber 4, the wastewater containing flocculant adsorbs the oil and suspended particles contained in the wastewater to form solid sludge particles due to the flocculation effect, and gathers towards the center of the vortex in the vortex.

[0055] The central sludge collection cylinder 5 is located axially in the center of the reaction chamber 4 and is used to collect sludge particles that gather at the center of the vortex.

[0056] The top of the reaction chamber 4 is the top of the main body 1, and the water outlet 6 is located on the top of the main body 1 for collecting the clean water that has separated sludge particles in the reaction chamber 4.

[0057] As a further embodiment of this example, the reaction chamber 4 includes a transition zone 7 and a vertical zone 8;

[0058] The sidewall of the transition zone 7 has a funnel-shaped structure, with the lower end diameter being the same as the diameter of the rising cylinder 3 and the upper end diameter being the same as the diameter of the vertical zone 8. The diameter of the area between the upper and lower ends varies uniformly with the height.

[0059] The diameter of the vertical zone 8 is the same as the inner wall diameter of the main body 1, which is larger than the diameter of the rising cylinder 3.

[0060] As a further embodiment of this embodiment, a mud collection pipe 9 is provided at the lower end of the central mud collection cylinder 5;

[0061] The end of the sludge collection pipe 9 away from the central sludge collection cylinder 5 extends from the reaction chamber 4 to the sludge thickening chamber 10;

[0062] The sludge thickening chamber 10 is located below the reaction chamber 4 and is surrounded by the inner wall of the main body 1, the outer wall of the reaction chamber 4 and the outer wall of the rising cylinder 3. It is used to collect and thicken the sludge in the central sludge collection cylinder 5.

[0063] As a further embodiment of this invention, a sludge discharge pipe 11 is provided at the bottom of the sludge thickening chamber 10 for discharging the sludge from the lower layer of the sludge thickening chamber 10.

[0064] As a further embodiment of this embodiment, a clarifying ring plate 12 is also provided in the sludge thickening chamber 10;

[0065] The clarifying ring plate 12 is annular, and the inner diameter of the clarifying ring plate 12 is connected to the outer diameter of the reaction chamber 4. The outer diameter of the clarifying ring plate 12 is connected to the inner wall of the main body 1.

[0066] The clarification ring plate 12 divides the sludge thickening chamber 10 into a thickening zone 13 and a clarification zone 14.

[0067] The clarifying ring plate 12 is provided with water-permeable holes 24 for connecting the concentration zone 13 and the clarification zone 14, allowing the upper clear liquid of the concentration zone 13 to enter the clarification zone 14. (e.g.) Figure 4 (As shown)

[0068] As a further embodiment of this invention, a drainage tube 15 is also included;

[0069] The drainage tube 15 is disposed on the side wall of the clarification zone 14 and is used to drain the clear liquid from the clarification zone 14.

[0070] As a further embodiment of this example, it also includes an inclined tube structure 16 and an inclined tube support 17;

[0071] The inclined tube structure 16 is installed in the reaction chamber 4 via an inclined tube support 17;

[0072] The lower end face of the inclined tube structure 16 is not lower than the upper end of the central mud collecting cylinder 5;

[0073] The inclined tube support 17 is fixedly connected to the inner wall of the main body 1;

[0074] The inclined tube structure 16 is used to re-aggregate the small particles remaining in the clear water that rises to the inclined tube structure 16, forming larger particles.

[0075] As a further embodiment of this invention, a flow stabilizer 18 is also included;

[0076] The flow stabilizer 18 is installed on the inclined tube support 17 and located at the center of the inclined tube structure 16. It is used to reduce the impact force and fluctuation of the water flow, so that larger particles that are accumulated at the inclined tube structure 16 fall down, and make the water flow above the flow stabilizer 18 more stable, which is conducive to collection at the outlet pipe 6.

[0077] As a further embodiment of this invention, a mud discharge ring plate 19 is also included;

[0078] The sludge discharge ring plate 19 is disposed at the bottom of the main body 1 and is used to install the sludge discharge pipe 11.

[0079] As a further embodiment of this invention, a mud collection cover 20 is also included;

[0080] The sludge collection hood 20 is installed at the sludge outlet of the sludge collection pipe 9 to prevent sludge from splashing at the sludge collection pipe 9 and reduce the sludge flow rate, thereby slowing down the sludge flow rate in the sludge thickening chamber 10.

[0081] As a further embodiment of this invention, an upper manhole 21 and a lower manhole 22 are also included;

[0082] The upper manhole 21 and the lower manhole 22 are respectively located on the side wall of the main body 1 and are used for safety inspection of the equipment.

[0083] As a further embodiment of this invention, an internal support structure 23 is also included;

[0084] The internal support structure 23 is used to support the internal structure of the device;

[0085] Specifically, it is used to support reaction chamber 4 and the central mud collection pipe.

[0086] like Figure 2As shown, in this embodiment, when the suspended sludge clarification device is working, wastewater containing flocculant is introduced into the rising cylinder 3 from the outside through the inlet pipe 2 and a vortex is generated in the rising cylinder 3. After the vortex reaches the reaction chamber 4, with the flocculation effect, the oil and suspended particles contained in the wastewater are adsorbed to form solid sludge particles, which gather towards the center of the vortex to form a sludge layer. The sludge layer enters the central sludge collection cylinder 5 and descends. The clear water continues to rise and passes through the inclined tube structure 16 and the flow stabilizer 18 before being discharged from the outlet pipe 6 at the top of the main body 1. During this process, the inclined tube structure 16 will gather the small part of the remaining particles in the clear water that rises to the inclined tube structure 16 again to form larger sludge particles. After the sludge settles, it is discharged from the central sludge collection pipe. After the sludge reaches the bottom of the central sludge collection pipe, it is discharged from the sludge collection pipe 9 to the sludge thickening chamber 10. In the sludge thickening chamber 10, the sludge settles at the bottom of the sludge thickening chamber 10, while the clear liquid is suspended at the top. After passing through the water permeable holes 24 of the clarification ring plate 12, it enters the clarification zone 14 and is discharged through the drainage pipe 15. The sludge at the bottom is discharged through the sludge discharge pipe 11.

[0087] By adopting the above technical solution, this application has the following beneficial effects:

[0088] (1) By combining eddy current and flocculation effect, the device can quickly adsorb oil and suspended particles in sewage to form solid sludge particles and effectively gather them into the central sludge collection cylinder 5, thereby improving the purification efficiency and quality of sewage.

[0089] (2) The design of the sludge thickening chamber 10 enables the collected sludge to be further thickened, reducing the volume of sludge and facilitating subsequent treatment and disposal. At the same time, the setting of the clarifying ring plate 12 and its permeable holes 24 achieves effective separation of the clear liquid and sludge.

[0090] (3) The design of the transition zone 7 and vertical zone 8 of the reaction chamber 4, as well as the introduction of the inclined tube structure 16 and the flow stabilizer 18, not only optimize the internal flow field of the device, but also improve the stability of the water flow, ensuring the effective aggregation and settling of sludge particles, while reducing the impact and wear of the water flow on the device.

[0091] Example 2

[0092] like Figure 5 As shown, the suspended sludge clarification device provided in this embodiment differs from that in embodiment 1 in that a timed switching valve 25 is connected to the diversion pipe 15.

[0093] The timed switching valve 25 is connected to a return water pipe 26 and a drain pipe 27.

[0094] The liquid in the drainage pipe 15 flows to the return water pipe 26 or the drain pipe 27 through the timed switching valve 25;

[0095] The other end of the return water pipe 26 is connected to the bottom of the transition zone 7 of the reaction chamber 4;

[0096] The return water pipe 26 is connected to the reaction chamber 4 in the tangential direction of the transition zone 7;

[0097] The drain pipe 27 is connected to an external collection device to collect water from the clarification zone 14.

[0098] As a further implementation of this embodiment, the timed switching valve 25 switches the connection status of the return water pipe 26 and the drain pipe 27 according to a preset time interval. For example, within 15 minutes, the water in the diversion pipe 15 is connected to the return water pipe 26 from the diversion pipe 15, and then within the next 5 minutes, the water in the diversion pipe 15 is connected to the drain pipe 27 from the diversion pipe 15.

[0099] Because the vertical height of the clarification zone 14 is higher than the bottom of the transition zone 7, some of the gravitational potential energy of the water in the drainage pipe 15 is converted into kinetic energy after flowing to the return water pipe 26, giving the water a faster speed. Since the water enters the transition zone 7 tangentially, it provides kinetic energy to the eddy current, increasing its speed and causing the sludge to concentrate more towards the central sludge collection pipe.

[0100] By adopting the above technical solution, this application has the following beneficial effects:

[0101] (1) The water in the diversion pipe 15 is periodically switched to the return water pipe 26 by the timed switching valve 25, so that the water enters the transition zone 7 of the reaction chamber 4 at a faster speed in a tangential direction, which provides additional kinetic energy for the vortex, effectively enhances the speed and intensity of the vortex, helps to accelerate the aggregation of sludge particles to the central sludge collection pipe, and improves the efficiency of sludge treatment.

[0102] (2) The setting of the timed switching valve 25 enables the water flow in the diversion pipe 15 to switch periodically between the return water pipe 26 and the drain pipe 27. This ensures that the water in the clarification zone 14 can be discharged and collected periodically, and also allows some water to be reintroduced into the reaction chamber 4 through the return water pipe 26 to participate in the formation of vortex and the accumulation of sludge. This optimizes the sludge treatment process and improves the overall processing capacity and flexibility of the device.

[0103] (3) Since the water in the return pipe 26 enters the transition zone 7 at high speed in the tangential direction, the gravitational potential energy of the water is converted into kinetic energy. The vortex effect can be enhanced without the need for additional power equipment, thereby improving the energy utilization efficiency and reducing the operating cost.

[0104] (4) The mechanism of periodically switching the direction of water flow helps to balance the water flow state inside the device, avoids the problem of sedimentation or blockage inside the device caused by a single direction of water flow for a long time, and enhances the stability and reliability of the device.

[0105] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
