Description

Technical Field

[0001] This application relates to the field of sewage treatment, and particularly to an ultrasonic suspended solids sedimentation and settling tank. Background Art

[0002] As a key part of the water treatment process, the coke quenching water sedimentation tank is responsible for sedimenting and separating pollutants and purifying water bodies. However, in actual production, the daily water treatment volume of the coke quenching water sedimentation tank is large, and the sedimentation efficiency often fails to meet expectations. Currently, the most commonly used is the ultrasonic sedimentation device.

[0003] In the existing ultrasonic sedimentation tank, ultrasonic waves are used to accelerate the sedimentation of suspended solids in the sedimentation tank. Since there is a flocculation effect among the suspended particles in the coke quenching water, when these flocculent particles enter the sedimentation tank, due to the uneven distribution of the water flow velocity in the sedimentation tank and the existence of a velocity gradient, particle collisions will occur, promoting flocculation. The ultrasonic device can accelerate this process through ultrasonic waves. Theoretically, under the action of ultrasonic waves, the acceleration effect of the sedimentation of suspended solids in any area of the ultrasonic sedimentation tank should be relatively obvious. However, it is found during use that the acceleration effect of the sedimentation of suspended solids in the area far from the sewage inlet is not obvious, and even the sedimentation speed of the suspended solids may decrease.

[0004] Regarding the problem that the acceleration effect of the sedimentation of suspended solids in the area far from the sewage inlet of the existing ultrasonic sedimentation tank is not obvious and even the sedimentation speed of the suspended solids may decrease, no effective solution has been proposed yet.

[0027] Please refer to Figure 1 and Figure 3 , this embodiment provides an ultrasonic suspended matter sedimentation and precipitation tank, which includes a sedimentation tank 10, two first drainage plates 4 and two second drainage plates 5 installed in the sedimentation tank 10, and a plurality of ultrasonic vibration plates 3 installed on a support net 2.

[0028] Please refer to Figure 2, wherein, the installation position of the support net 2 is as follows: a trough steel frame 1 is installed in the middle of the sedimentation tank 10, and the support net 2 is installed on the trough steel frame 1. The material of the support net 2 is corrosion-resistant metal. The support net 2 covers the cross-section in the middle of the sedimentation tank 10, and a primary buffer sedimentation area is formed between the middle and the bottom of the sedimentation tank 10. The trough steel frame 1 includes a cross bar 11, a first vertical bar 12 and a second vertical bar 13. The first vertical bar 12 and the second vertical bar 13 divide the sedimentation tank 10 into a first area 21, a second area 22 and a third area 23; the first area 21, the second area 22 and the third area 23 include the vertical upper and lower area spaces of the corresponding support net 2. An inlet 101 and an outlet 102 are respectively arranged on the first side and the second side of the sedimentation tank 10, and the vertical projections of the inlet 101 and the outlet 102 of the sedimentation tank 10 are respectively at both ends of the cross bar 11. Two first diversion plates 4 and two second diversion plates 5 are mirror-symmetrically distributed on both sides of the cross bar 11, and the two second diversion plates 5 are between the two first diversion plates 4; that is, the two first diversion plates 4 are located on the outside, and the two second diversion plates 5 are located on the inside. The first ends of the two first diversion plates 4 and the two second diversion plates 5 are installed at the inlet 101 and are used for equally dividing the water flow at the inlet 101, that is, the first ends of the four diversion plates are all installed in one direction and are used for equally dividing the water flow. In this embodiment, the water flow at the inlet 101 is equally divided into five water flows, and these five water flows will flow into the first area 21, the second area 22 and the third area 23 of the primary buffer sedimentation area. Since the first area 21, the second area 22 and the third area 23 are arranged in sequence, the flow velocities of the water flows in the first area 21, the second area 22 and the third area 23 also change in a gradient manner, wherein the water flow velocity near the inlet 101 is fast, and the water flow velocity far from the inlet 101 is slow, and the water flow velocities are different. According to the research of this application, it is found that for the same water flow, if the energy of the ultrasonic vibration plate is lower than the normal value, it will cause insufficient sludge sedimentation. If the energy of the ultrasonic vibration plate is at the normal value, it will cause the sludge sedimentation to be in the ideal range. If the energy of the ultrasonic vibration plate is higher than the normal value, it will still cause insufficient sludge sedimentation. The reason for this is that when the energy of the ultrasonic vibration plate is higher than the normal value, the sludge state in the treatment area will quickly go through three stages. The first stage is the rapid sedimentation of the sludge. The second stage is that the sludge has almost settled, and then it quickly enters the third stage, that is, the settled sludge is excited again by the energy under the action of the ultrasonic wave, thereby making the water quality turbid again, and the effect of accelerating sedimentation is not obvious or even reduced. Therefore, in order to solve the existing problem of overusing ultrasonic waves, the configuration of the ultrasonic vibration plate needs to be changed. After the research and test of this application, a new configuration scheme of the ultrasonic vibration plate is obtained:

[0029] The second ends of the two first drainage plates 4 extend to the first vertical rod 12, and the second ends of the two second drainage plates 5 extend to the second vertical rod 13; the two first drainage plates 4 divide the first area 21 into three first sub-areas, and the two second drainage plates 5 divide the second area 22 into three second sub-areas; A ultrasonic vibrating plates 3 are distributed in each of the two first sub-areas in contact with the boundary of the sedimentation tank 10, B ultrasonic vibrating plates 3 are distributed in each of the three second sub-areas, and C ultrasonic vibrating plates 3 are distributed in the third area 23; wherein, 2A > C > A > B. Simply put, the first area 21, the second area 22 and the third area 23 are further divided into multiple sub-areas according to the above-mentioned five water flow regions. Among them, the first area 21 is divided into three first sub-areas, and the second area 22 is divided into three second sub-areas. Refer to Figure 2 , the five water flows are from top to bottom in sequence. The first and fifth water flows are both fast water flows near the water inlet 101. The first and fifth water flows pass through most of the first area 21 and a small part of the second area 22. Therefore, the largest number of ultrasonic vibrating plates 3 are arranged in the first sub-areas for sedimentation treatment. The second, third and fourth water flows are all medium-speed water flows. The second, third and fourth water flows pass through a small part of the first area 21 and most of the second area 22. Also, because the water flow velocity decreases and the impurities decrease, medium numbers of ultrasonic vibrating plates 3 are arranged in the second sub-areas for sedimentation treatment. And the five water flows will finally converge in the third area 23. At this time, the water flow has the lowest level in terms of water quality sludge degree and flow velocity. Therefore, the number of ultrasonic vibrating plates arranged in the third area 23 must be lower than that in the first area 21. And because it is a convergence area, it is greater than the number of ultrasonic vibrating plates on any water flow path, that is, 2A > C > A > B.

[0030] In summary, by performing ultrasonic sedimentation operations on the water flows in different areas through the different numbers of ultrasonic vibrating plates 3 arranged in the first area 21, the second area 22 and the third area 23 respectively. The reduction of sedimentation efficiency caused by excessive use of ultrasonic waves can be avoided. In order to improve the sedimentation effect, the present application has obtained the optimal distribution amounts of ultrasonic vibrating plates in the first area 21, the second area 22, the third area 23 and the five water flow paths through experiments, that is, A is 3, B is 2, and C is 4. Thus, through this configuration, the sedimentation effects in each area in the sedimentation tank 10 are improved synchronously and the treatment effect is more uniform, solving the problem that the acceleration effect of suspended matter sedimentation in the area far from the sewage inlet in the existing ultrasonic sedimentation tank is not obvious or even the sedimentation speed of suspended matter decreases.

[0031] If structural optimization is carried out, the second ends of the two first drainage plates 4 can be mirror-bent and extended to the first vertical rod 12, and the two first drainage plates 4 protrude towards the cross bar 11. The second ends of the two second drainage plates 5 can be mirror-bent and extended to the second vertical rod 13, and the two second drainage plates 5 protrude towards the cross bar 11. In this way, the water flow rates processed by the first sub-region and the second sub-region are more reasonable.

[0032] In a specific implementation, an ultrasonic generator 31 is installed in the middle of the inner wall of the sedimentation tank 10 away from the water inlet 101. The ultrasonic generator 31 is electrically connected to a plurality of ultrasonic vibration plates 3, and the plurality of ultrasonic vibration plates 3 are installed with staggered distribution between columns. A secondary inclined plate packing sedimentation area 103 is arranged in the upper-middle part of the sedimentation tank 10. An overflow weir 7 is arranged above the secondary inclined plate packing sedimentation area 103. The water outlet 102 is arranged on one side of the top of the sedimentation tank 10 away from the water inlet 101. An isolation film 9 is arranged on the inner wall of the sedimentation tank 10. The isolation film 9 is used to prevent the inner wall of the sedimentation tank 10 from being corroded and to isolate ultrasonic waves. The isolation film 9 is composed of a polyester fiber layer, a propylene-ethylene rubber layer, and an asphalt mineral wool layer stacked together. The polyester fiber layer is attached to the inner wall of the sedimentation tank 10. According to the property of the gradually changing water quality, the ultrasonic vibration plates 3 are installed on the support net 2 in a gradually decreasing density order from the water inlet 101 to the water outlet 102 in the horizontal position, and are arranged by the method of staggered distribution between columns. At the position of the water inlet 101, the ultrasonic waves are densely distributed to generate strong ultrasonic energy. Under the cavitation effect and mechanical action, the suspended particles are promoted to quickly aggregate, and larger flocs are formed near the turbulent water inlet, so as to achieve the purpose of rapid sedimentation. And the blockage caused by a large amount of impurities at the water inlet 101 can be removed in time through strong ultrasonic vibration. The sedimentation efficiency in the water body of the primary buffer sedimentation area near the water outlet 102 is relatively stable. The relatively sparse arrangement method can reduce the interference with the formed sediment. According to the above arrangement method, the cavitation effect sedimentation rate generated in the quenching water is thus greatly improved. The suspended matter that originally needed several hours to be preliminarily sedimented can reach a similar sedimentation effect in dozens of minutes. The equipment can treat more quenching water in the same time, improving the efficiency of the whole treatment process. The water inlet 101 and the water outlet 102 are respectively located at the lower part and the upper part on both sides of the secondary inclined plate packing sedimentation area. Due to the inclined plate packing as a buffer, the upper layer water outlet area is evenly distributed, effectively breaking the uneven water flow phenomenon caused by the design limitations of the water inlet 101 and the water outlet 102. Problems such as uneven horizontal and vertical velocity distributions and the formation of dead zones in local areas that often occur in traditional sedimentation tanks. In this design, the water flow is guided to the area away from the water inlet 101 through the baffle plate. The water flow near the water inlet is turbulent and has a small range, which is adapted to the densely arranged ultrasonic vibration plates. The water flow in the area away from the water inlet 101 is gentle and has a large range, and is matched with the relatively sparse arrangement of the ultrasonic vibration plates, so that the equipment configuration is precisely matched with the water flow characteristics, making full use of every space in the tank for sedimentation, and avoiding the situation that part of the water flow flows out quickly without sufficient sedimentation. To reduce the impact of ultrasonic waves on the personnel in the working environment, it can be arranged in the order of "asphalt mineral wool layer - propylene-ethylene rubber layer - polyester fiber layer" inside the sedimentation tank 10. The reasons are as follows:

[0033] - The asphalt mineral wool layer is close to the ultrasonic source: The asphalt mineral wool has good sound absorption performance. Its porous structure can make the ultrasonic waves reflect and scatter multiple times inside, consuming energy. Placing it in the innermost layer can preferentially absorb most of the ultrasonic waves.

[0034] - Intermediate transition of the ethylene-propylene rubber layer: Ethylene-propylene rubber has good elasticity, can effectively buffer ultrasonic vibrations, and has a certain sound insulation property. Placed in the middle, it can further block the remaining ultrasonic waves, reduce the intensity of their outward propagation, and at the same time reduce the fatigue damage of asphalt mineral wool caused by long-term exposure to ultrasonic waves.

[0035] - Polyester fiber layer as the outer layer: Polyester fiber has a dense texture, can block the transmission of ultrasonic waves, and can also protect the internal materials from being affected by the external environment, such as moisture, mechanical damage, etc., maintaining the stability of the overall sound insulation structure and better exerting the noise reduction effect.

[0036] In order to treat the settled sludge, a sludge area 6 can be set at the bottom of the sedimentation tank 10, and a sludge outlet is provided in the sludge area 6 to discharge the sludge generated after sedimentation. Thus, the sludge can be quickly collected and treated, and a pipeline can be set in the sludge area 6 to directly export the sludge, improving the treatment efficiency.

[0037] In summary, in this embodiment, ultrasonic sedimentation operations are respectively performed on the water flows in different regions through the different numbers of ultrasonic vibration plates 3 provided in the first region 21, the second region 22, and the third region 23. This can avoid the reduction of sedimentation efficiency caused by excessive use of ultrasonic waves. To improve the sedimentation effect, the optimal distribution amounts of the ultrasonic vibration plates on the first region 21, the second region 22, the third region 23, and the five water flow paths are obtained through experiments, that is, A is 3, B is 2, and C is 4. Thus, through this configuration, the sedimentation effects in each region in the sedimentation tank 10 are synchronously improved and the treatment effect is more uniform, solving the problem in the prior art that the sedimentation speed of suspended matter in the region far from the water inlet of the ultrasonic sedimentation tank is lower than that in other regions; through the structural optimization of the first diversion plate 4 and the second diversion plate 5, the water flow rates processed in the first sub-region and the second sub-region are more reasonable; a sludge area 6 can be set at the bottom of the sedimentation tank 10, and a sludge outlet is provided in the sludge area 6 to discharge the sludge generated after sedimentation. Thus, the sludge can be quickly collected and treated, and a pipeline can be set in the sludge area 6 to directly export the sludge, improving the treatment efficiency; a isolation membrane 9 is provided to prevent the inner wall of the sedimentation tank 10 from being corroded and to achieve the effect of isolating ultrasonic waves, making the device operate more stably.
