Description

Technical Field

[0001] This utility model relates to the technical field of water purification and sludge treatment equipment, specifically to a water plant wastewater reuse device that integrates regulation, sedimentation, and concentration. Background Technology

[0002] With increasing environmental awareness, the issue of wastewater discharge from waterworks has received widespread attention. Typically, waterworks use a concentration process to bring the solids content of their wastewater up to the required level for sludge dewatering equipment. Concentrators are recognized as the most stable type of concentrator due to their simple structure, convenient operation and management, and strong adaptability to water volume and quality. They are also the mainstream sludge concentration process tank type used in waterworks today. After the sludge from the waterworks is discharged, it undergoes sludge-water separation in the concentration tank. The supernatant is reused in the recycling tank, while the concentrated sludge at the bottom enters the balancing tank and is then dewatered in the dewatering room.

[0003] To prevent the supernatant from mixing with the sludge, existing sludge thickening tanks typically have an overflow pipe or a ring-shaped water collection and outlet pipe at the top. This allows the supernatant to overflow, achieving sludge-water separation. In actual sludge discharge processes at waterworks, the flow rate of the discharged sludge varies significantly over time. When the discharge volume is small, the hydraulic load on the sludge thickening tank is low, resulting in clearer effluent. However, when the discharge volume is large, to prevent the supernatant from becoming turbid due to impact, a regulating tank is usually installed upstream of the sludge thickening tank, or the tank itself is designed to be larger. This results in a large footprint for the overall structure and higher infrastructure investment.

[0004] A Chinese patent with patent number ZL201921860662.0 discloses a thickening tank that divides the interior into upper and lower layers, each with its own annular water collection and outlet pipe, allowing each layer to discharge water independently and improving thickening efficiency. However, in actual use, when the sludge discharge volume is large, the sludge in the upper layer mixes with the clear liquid in the lower layer during the settling process, resulting in the clear liquid flowing out of the lower layer containing sludge, and the actual thickening effect is not good. Similarly, when the sludge discharge volume is small, the upper thickening tank cannot be used, which is wasteful and cannot achieve an effective process of discharging clear water. Its structure and device are relatively complex, which is not conducive to improvement and processing based on existing thickening tanks, and the practical effect is not ideal. Utility Model Content

[0005] The purpose of this invention is to provide a water plant wastewater reuse device that integrates regulation, sedimentation, and concentration, which can be used for both large-flow and small-flow sludge discharge water concentration and effectively discharge clear liquid.

[0006] This utility model is achieved through the following technical solution: a water plant wastewater reuse device integrating regulation, sedimentation, and concentration, comprising a tank body, a central reaction cylinder arranged in the middle of the tank body, the central reaction cylinder being connected to an inlet pipe extending out of the tank body, a sludge accumulation zone at the bottom of the tank body and a clarification zone at the top, the sludge accumulation zone being connected to a balance water tank through a sludge pipe; several layers of annular water collection and outlet pipes distributed around the inner wall of the clarification zone at the top of the tank body are fixedly arranged, each layer of annular water collection and outlet pipes being connected to a main outlet pipe through a pipe extending out of the tank body, the main outlet pipe leading to a reuse water tank; several water collection holes are provided at the bottom of each layer of annular water collection and outlet pipes, several vent holes are provided at the top of each layer of annular water collection and outlet pipes, and an electric butterfly valve is also provided on the pipe connecting each layer of annular water collection and outlet pipes to the main outlet pipe.

[0007] The principle of this technical solution is as follows: multiple layers of annular water collection and outlet pipes are added to the inner wall of the clarification zone in the upper part of the pool. Each layer of annular water collection and outlet pipes has a water collection hole at the bottom and a vent hole at the top. When the clear liquid in the upper clarification zone exceeds the water collection hole at the bottom of the annular water collection and outlet pipe, it can be discharged into the main outlet pipe through the small hole and finally enter the reuse water tank. The sludge in the lower part enters the lower sludge accumulation zone and is discharged through the sludge pipe. The sludge concentration process of the sludge discharge water is achieved by controlling the opening and closing of each layer of electric butterfly valves to control the on / off of each layer of annular water collection and outlet pipes. Therefore, the annular water collection and outlet pipes at different heights determine the volume of sludge discharge water in the pool, realizing the adjustment of the actual volume of the pool. In this way, the pool can realize the function of a regulating pool without the need to set up an additional regulating pool, reducing the structure, thereby saving the land area and reducing the investment in infrastructure. The water collection hole is located at the bottom of the annular water collection outlet pipe, with the opening facing downwards. This prevents sludge from entering the drain pipe, and the small diameter of the water collection pipe ensures maximum separation of mud and water.

[0008] To better realize this utility model, the water inlet pipe is further equipped with an electromagnetic flow meter capable of measuring the water inlet flow rate, and the pool body is also equipped with a level gauge capable of displaying the liquid level in the pool body.

[0009] To better realize this utility model, furthermore, the inner wall of the upper clarification zone of the pool is provided with several multi-layer support frames made of angle steel, and each layer of annular water collection and outlet pipe is fixed in the corresponding multi-layer support frame by clamps.

[0010] To better realize this utility model, a central drive thickener is further provided in the sludge accumulation area below the central reaction cylinder, and a sludge collection pit is provided at the bottom of the pool below the central drive thickener. The sludge collection pit is connected to the balance water pool through a sludge pipe.

[0011] To better realize this utility model, the bottom of the sludge accumulation area is a sloped surface that tilts towards the sludge collection pit.

[0012] To better realize this utility model, an overflow and venting pipe is further provided outside the pool body. The upper part of the overflow and venting pipe is connected to the top of the clarification zone of the pool body, and the lower part of the sludge accumulation zone of the pool body is connected to the overflow and venting pipe through a pipe equipped with a valve.

[0013] To better realize this utility model, a sludge cam pump is further installed on the sludge pipe.

[0014] To better realize this utility model, a conical baffle plate located above the central drive concentrator is further installed at the bottom of the central reaction cylinder.

[0015] To better realize this utility model, the inner wall of the upper clarification zone of the pool is further provided with four layers of annular water collection and outlet pipes, and the water collection holes at the bottom of each annular water collection and outlet pipe are evenly distributed at equal intervals.

[0016] To better realize this utility model, the number of vent holes at the top of each layer of annular water collection and outlet pipe is not less than 6, and the diameter of both the water collection hole and the vent hole is not greater than 40mm.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] (1) This utility model has several layers of annular water collection and outlet pipes distributed around the inner wall of the clarification zone in the upper part of the pool. The bottom of the annular water collection and outlet pipe has a water collection hole and the top has an exhaust hole. When the water level exceeds the water collection hole of the annular water collection and outlet pipe, the water flows out directly through the annular water collection and outlet pipe. This realizes the discharge of clear water in the clarification zone. The opening and closing of each layer of electric butterfly valve can realize the control of the on / off of each layer of annular water collection and outlet pipe. The different heights of the annular water collection and outlet pipes determine the volume of mud-discharge water in the pool, realizing the adjustment of the actual volume of the pool. In this way, the pool can realize the function of a regulating pool without the need to set up an additional regulating pool, reducing the structure, so as to save the land area and reduce the investment in infrastructure.

[0019] (2) The present invention uses an annular water collection and outlet pipe installed on the inner wall of the clarification zone. The water collection hole allows clear water to enter the annular water collection and outlet pipe. The diameter of the water collection hole is small and the water collection hole is located at the bottom of the annular water collection and outlet pipe, which can ensure the separation of mud and water to the greatest extent.

[0020] (3) By setting up multiple drainage pipes, this utility model can solve the problem of integrating the functions of the equalization tank and the thickening tank into one structure, realizing multiple functions of sedimentation, sludge thickening and sludge-water separation. It can withstand the impact of uneven discharge of sludge water, and the structure is relatively simple. It can directly improve the existing sludge thickening tank. It is practical and suitable for widespread application. Attached Figure Description

Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to 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.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0031] The main structure of this embodiment is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the system includes a tank body 1, with a central reaction cylinder 2 located in the middle of the tank body 1. The central reaction cylinder 2 is connected to an inlet pipe 3 extending out of the tank body 1. The lower part of the tank body 1 is a sludge accumulation zone 11, and the upper part is a clarification zone 12. The sludge accumulation zone 11 is connected to a balance water tank via a sludge pipe 4. Several layers of annular water collection and outlet pipes 5 are fixedly installed on the inner wall of the upper clarification zone 12 of the tank body 1. Each layer of annular water collection and outlet pipes 5 is connected to a main outlet pipe 6 via a pipe extending out of the tank body 1. The main outlet pipe 6 leads to a recycled water tank. Several water collection holes 51 are provided at the bottom of each layer of annular water collection and outlet pipes 5, and several vent holes 52 are provided at the top of each layer of annular water collection and outlet pipes 5. An electric butterfly valve 7 is also installed on the pipe connecting each layer of annular water collection and outlet pipes 5 to the main outlet pipe 6.

[0032] according to Figure 1 It can be seen that the pool body 1 is set in a cylindrical shape. In fact, the pool body 1 can be set in a cylindrical shape or a rectangular shape.

[0033] The specific implementation process is as follows: the sludge discharge water from the waterworks enters the central reaction cylinder 2 in the middle of the tank 1 through the inlet pipe 3. The outlet of the central reaction cylinder 2 is equipped with a gradually expanding funnel-shaped opening. Coagulants such as PAM can be added to the central reaction cylinder 2 to improve the sludge settling effect. After the sludge discharge water is treated by the coagulant, it forms flocculent sludge that is easy to settle. Due to the presence of the gradually expanding funnel-shaped opening, the flow velocity at the opening is reduced, preventing the flocculent sludge from breaking. The flocculent sludge then settles into the sludge accumulation zone 11, and is transported to the balance tank through the sludge pipe 4. The clear liquid in the clarification zone 12 at the top of the pool 1 enters the annular water collection and outlet pipe 5 through the water collection hole 51 at the bottom of the annular water collection and outlet pipe 5. The vent hole 52 on the annular water collection and outlet pipe 5 prevents the formation of air pockets inside the annular water collection and outlet pipe 5, and at the same time ensures the pressure balance inside and outside the annular water collection and outlet pipe 5, which has an anti-buoyancy function. In this way, the clear liquid finally enters the main outlet pipe 6 through the annular water collection and outlet pipe 5 and finally flows to the reclaimed water pool.

[0034] The level of the liquid in the pool 1 is determined by the opening and closing of the electric butterfly valve 7 on each ring-shaped water collection and outlet pipe 5. Therefore, the actual volume of sludge discharge water in the pool 1 can be adjusted by controlling the opening and closing of the electric butterfly valve 7 on each ring-shaped water collection and outlet pipe 5. In this way, the pool 1 can realize the function of an equalization pool without the need to set up an additional equalization pool.

[0035] When the amount of sludge discharged is small and the liquid level in the pool 1 is low, the clarification zone 12 in the pool 1 only submerges the water collection hole 51 of the bottommost annular water collection pipe 5. At this time, the electric butterfly valves 7 on the upper annular water collection pipe 5 are all closed, and only the electric butterfly valve 7 of the bottommost annular water collection pipe 5 is open, so the clear liquid is discharged through the bottommost annular water collection pipe 5.

[0036] When the amount of sludge discharged is large, the clarification zone 12 in the pool 1 will submerge the water collection hole 51 of the corresponding layer's annular water collection outlet pipe 5. Then, the electric butterfly valve 7 on the corresponding layer's annular water collection outlet pipe 5 will be opened, and the electric butterfly valves 7 of the lower annular water collection outlet pipe 5 and the upper annular water collection outlet pipe 5 of the layer will be closed. Only the clear liquid will be discharged through the annular water collection outlet pipe 5 of the layer.

[0037] When the sludge discharge volume is extremely large, the clarification zone 12 in the pool 1 submerges the water collection hole 51 of the uppermost annular water collection outlet pipe 5, then the electric butterfly valve 7 on all the lower annular water collection outlet pipes 5 is closed, and only the uppermost annular water collection outlet pipe 5 is used to discharge the clear liquid.

[0038] By controlling the electric butterfly valve 7, it can be ensured that only the clear liquid from the top layer of the pool 1 enters the main outlet pipe 6, and the actual volume of the pool 1 can be controlled. Example 2:

[0039] This embodiment, based on the above embodiment, further adds an electromagnetic flowmeter 16 and a level gauge, such as... Figure 1 , Figure 3 As shown, an electromagnetic flowmeter 16 capable of measuring the inlet water flow rate is installed on the inlet pipe 3, and a level gauge capable of displaying the liquid level inside the pool 1 is also installed inside the pool body 1. The electromagnetic flowmeter 16 can display the flow rate of the sludge-discharging water in the inlet pipe 3, while the level gauge displays the liquid level inside the pool body 1. The flow rate of the clear liquid flowing out of each layer of annular water collection outlet pipe 5 is different. In this way, the opening and closing of the electric butterfly valve 7 on each layer of annular water collection outlet pipe 5 can be controlled based on the flow rate of the sludge-discharging water and the liquid level inside the pool body 1, thereby selecting the corresponding layer of annular water collection outlet pipe 5 for clear liquid discharge and realizing the adjustment of the actual volume of the pool body 1. This ensures that when the flow rate is low and the liquid level is low, the water is discharged from the lower annular water collection outlet pipe 5, resulting in low hydraulic load and short residence time; when the flow rate is high and the liquid level is high, the water is discharged from the upper annular water collection outlet pipe 5, resulting in high hydraulic load and long residence time, while simultaneously ensuring that the turbidity of the effluent meets the requirements for reuse.

[0040] In addition, the addition of an electromagnetic flowmeter 16 and a level gauge can be used in conjunction with the design of a control system to control the opening and closing of the electric butterfly valves 7 on each layer. Through the signals fed back from the electromagnetic flowmeter 16 and the level gauge, the opening and closing of the electric butterfly valves 7 on each layer is automatically controlled. This allows the control system to automatically open the electric butterfly valves 7 on the corresponding layer based on the set water level and flow rate signals when the flow rate fluctuates irregularly. By adjusting the actual volume of the tank 1, the system can withstand and regulate the uneven impact of the sludge discharge flow. The other parts of this embodiment are the same as those in the above embodiment and will not be repeated. Example 3:

[0041] This embodiment, based on the above embodiment, further defines the fixing relationship between the annular water collection outlet pipe 5 and the pool body 1, such as... Figure 4 , Figure 5 As shown, the inner wall of the upper clarification zone 12 of the pool body 1 is provided with several multi-layer support frames 13 made of angle steel, and each layer of annular water collection and outlet pipe 5 is fixed in the corresponding layer of multi-layer support frame 13 by clamps 14. According to Figure 1 and Figure 4 It can be seen that the pool body 1 is set in a cylindrical shape, therefore the multi-layer support frame 13 is evenly distributed in a ring shape along the inside of the pool body 1, according to Figure 4 It can be seen that the optimal number is 18 to achieve stable fixation of the multi-layer annular water collection and outlet pipe 5. The specific structure of the multi-layer support frame 13 is as follows: Figure 5 As shown, it is made of several layers of angle steel, with the lower part supported by angle steel. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again. Example 4:

[0042] This embodiment, based on the above embodiment, further defines the structure within the mud accumulation zone 11, such as... Figure 2 , Figure 3As shown, a central drive thickener 8 is installed in the sludge accumulation zone 11, located below the central reaction cylinder 2. Below the central drive thickener 8 is a sludge collection pit 9 located at the bottom of the tank body 1. The sludge collection pit 9 is connected to the balance tank via a sludge pipe 4. The central drive thickener 8 includes a drive motor installed at the top of the tank body 1, a drive shaft extending into the tank body 1, and a stirring grid fixed at the lower part of the drive shaft. The stirring grid is located in the sludge accumulation zone 11 and can adsorb flocculent sludge, concentrating and collecting the sludge in the sludge accumulation zone 11, and finally scraping it into the sludge collection pit 9 at the bottom of the sludge accumulation zone 11. Finally, the sludge in the sludge collection pit 9 is transported to the balance tank via the sludge pipe 4. The other parts of this embodiment are the same as those in the above embodiment and will not be described again. Example 5:

[0043] This embodiment, based on the above embodiment, further defines the structure of the mud accumulation zone 11, such as... Figure 2 , Figure 3 As shown, the bottom of the sludge accumulation area 11 is an inclined surface that slopes towards the sludge collection pit 9. This arrangement allows the sludge to better converge into the sludge collection pit 9 by utilizing gravity. The other parts of this embodiment are the same as those in the above embodiment and will not be described again. Example 6:

[0044] This embodiment, based on the above embodiment, further adds an overflow and vent pipe 10, such as... Figure 1 , Figure 2 As shown, an overflow and venting pipe 10 is also provided outside the pool body 1. The upper part of the overflow and venting pipe 10 is connected to the top of the clarification zone 12 of the pool body 1, and the lower part of the sludge accumulation zone 11 of the pool body 1 is connected to the overflow and venting pipe 10 through a pipe equipped with a valve. The overflow and venting pipe 10 performs two functions: venting and overflowing. Its upper overflow port overflows the clear liquid in the upper clarification zone of the pool body 1, which can prevent the pool body 1 from overflowing. The lower pipe is connected to the sludge accumulation zone 11. After the sludge in the sludge collection pit 9 is drained, the sewage in the sludge accumulation zone 11 is vented through the lower pipe. The other parts of this embodiment are the same as those in the above embodiment and will not be described again. Example 7:

[0045] This embodiment, based on the above embodiment, further adds a sludge cam pump 15, such as... Figure 1 , Figure 2 As shown, a sludge cam pump 15 is also installed on the sludge pipe 4. The sludge cam pump 15 mainly provides power for the sludge in the sludge pipe 4, allowing the sludge to enter the balance tank. The sludge cam pump 15 is also equipped with a maintenance and flushing pipe, which can be used to maintain and flush the sludge pipe 4 after the sludge has been discharged. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again. Example 8:

[0046] This embodiment, based on the above embodiment, further adds a conical baffle 17, such as... Figure 2 Figure 3 As shown, a conical baffle 17 is installed at the bottom of the central reaction cylinder 2, above the central drive thickener 8. The conical baffle 17 is designed to prevent the sludge discharge water from directly entering the sludge accumulation area 11 of the tank 1 through the central reaction cylinder 2. Instead, it allows the sludge discharge water to diffuse outwards and slow down the flow rate, making it easier for the sludge and water to separate, for the bottom sludge to settle and concentrate, and preventing the sludge discharge water from disturbing the already concentrated sludge at the bottom, thus affecting the concentration process of the sludge thickener. Other parts of this embodiment are the same as those in the above embodiment and will not be described again. Example 9:

[0047] This embodiment, based on the above embodiment, further defines the structure of the annular water collection and outlet pipe 5. Four layers of annular water collection and outlet pipes 5 are fixed to the inner wall of the upper clarification zone 12 of the pool body 1, with the water collection holes 51 at equal intervals evenly distributed at the bottom of each layer. To ensure the normal water discharge function of the annular water collection and outlet pipes 5, it is further preferred that there are four layers of annular water collection and outlet pipes 5. That is, the pool body 1 has four options for volume adjustment based on the number of layers of annular water collection and outlet pipes 5, and the number and distribution of water collection holes 5 can be increased or decreased according to actual conditions. Since the water collection holes 51 themselves have a filtering effect on sediment, metal filter screens can be installed on the water collection holes 51 to further improve their filtering effect and ensure that the outflowing clear liquid does not contain sediment. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated.

[0048] Example 10:

[0049] Based on the above embodiments, this embodiment further defines the structure of each layer of annular water collection and outlet pipe 5. The number of vent holes 52 at the top of each layer of annular water collection and outlet pipe 5 is not less than 6, and the diameters of both the water collection holes 51 and the vent holes 52 are not greater than 40mm. The vent holes 52 on the annular water collection and outlet pipe mainly prevent the formation of air pockets inside the annular water collection and outlet pipe 5, and simultaneously ensure pressure balance inside and outside the annular water collection and outlet pipe 5, providing anti-buoyancy functionality. This prevents the clear liquid in the clarification zone 12 from failing to enter the annular water collection and outlet pipe 5 through the water collection holes 51 at the bottom of the annular water collection and outlet pipe 5. Therefore, the number of vent holes 52 does not need to be excessive; preferably, not less than 6. After being submerged by the clear liquid, the vent holes 52 must also achieve a certain filtration effect; therefore, their diameter, along with that of the water collection holes 51, cannot be too large, preferably not greater than 40mm. A filter metal mesh can also be installed at the opening of the vent holes 52. The other parts of this embodiment are the same as those in the above embodiments and will not be repeated.

[0051] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
