Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a cyclone aerator and a cyclone aeration device having the same. Background Art

[0002] Related technologies indicate that in the treatment of high-concentration wastewater, particularly high-ammonia nitrogen wastewater, such as landfill leachate, hazardous waste treatment wastewater, slaughterhouse wastewater, and chemical wastewater, fans are required to supply large amounts of oxygen to aeration tanks to remove ammonia nitrogen from the wastewater. To improve the efficiency of oxygen supply and dissolved oxygen in wastewater, aerator technology is constantly evolving. The choice of aerator not only affects the effectiveness of wastewater biochemical treatment but also directly impacts land usage, investment, operational stability, and fan energy consumption.

[0003] Currently, there are various aerobic aeration systems available both domestically and internationally, primarily including microporous aerators, jet aerators, and cyclone aerators. Initially installed, microporous aerators offer high oxygen dissolution efficiency and excellent biochemical treatment results. However, over time, the micropores in the aerators gradually shrink and become clogged, increasing fan energy consumption and even damaging the fan. Jet aerators, connected to a compressed air pipeline via a water pump, inject water to create fine bubbles. The air trapped in the bubbles fully contacts the water, dissolving oxygen into the water and achieving the desired aeration effect. The jet aerator has high oxygen dissolving efficiency, but high energy consumption, and requires the fan and water pump to operate simultaneously. In addition, the equipment mainly relies on imports, and the failure rate of domestic equipment is high. In the swirl aeration device, the air inlet pipe is arranged on the side of the cylinder, and an upward elbow is connected to the air inlet position of the cylinder. The air inlet pipe is arranged on the side, and the fan will vibrate when blowing air. After long-term operation, fatigue fracture will occur at the connection with the cylinder, and the aerator will be damaged. Secondly, when the aeration tank fan equipment is overhauled, the sludge will block the upward elbow under the action of gravity. When the equipment is restored to operation after the overhaul is completed, aeration will fail and even damage the fan. In addition, the currently disclosed swirl aerator cylinder structure is complex, difficult to process, and expensive, and the multi-layer blade structure is easy to loosen and fall off under the scouring action of water, thereby losing the function of the aerator.

[0032] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0033] Reference below Figures 1 to 4 A cyclone aerator 2 according to an embodiment of the first aspect of the present invention will be described.

[0034] like Figure 2 As shown, the cyclone aerator 2 according to the first embodiment of the present invention includes: a base 21, a cylinder 22, an air inlet pipe 23, an air flow guide 24 and a bubble generator 25.

[0035] Specifically, the cylinder 22 is arranged on the base 21, the axis of the cylinder 22 extends in the up and down directions, and the top and bottom of the cylinder 22 are open; the air inlet pipe 23 extends into the cylinder 22 from the top of the cylinder 22, and the air inlet pipe 23 extends along the axial direction of the cylinder 22 to the lower part of the cylinder 22; the air flow guide 24 is arranged in the cylinder 22, and a guide channel is formed in the air flow guide 24, the guide channel has an air flow inlet and multiple air flow outlets 2421, the air flow inlet is connected to the air inlet pipe 23, the multiple air flow outlets 2421 are rotationally symmetrical about the central axis of the cylinder 22, and the air flow outlets 2421 are configured to be suitable for spraying air flow obliquely upward and along the circumferential direction of the cylinder 22; the bubble generator 25 is arranged above the air flow guide 24, and the bubble generator 25 includes multiple bubble cutting impellers 251, and the multiple bubble cutting impellers 251 are arranged at intervals in the axial direction of the cylinder 22. Therefore, in this embodiment, the air inlet pipe 23 is extended from the top of the cylinder 22 into the cylinder 22 for aeration, so that the cyclone aerator 2 is formed into a structure in which the air inlet pipe 23 takes in air from the center of the cylinder 22. Compared with the related technology in which the air inlet pipe 23 is connected through the side wall of the cylinder 22 and aeration is conducted into the cylinder 22 through an upward curved pipe with an opening, on the one hand, fatigue fracture at the connection between the air inlet pipe 23 and the cylinder 22 after long-term operation can be avoided, which may cause damage to the cyclone aerator 2. On the other hand, when the fan 1 of the cyclone aeration device 100 is overhauled, sludge is prevented from clogging the upward curved pipe under the action of gravity, which may cause the cyclone aerator 2 to be unable to aerate or even damage the fan 1. In addition, the multiple bubble cutting impellers 251 in this embodiment can refine the bubbles, increase the dissolved oxygen rate, and enhance the aeration effect.

[0036] The working principle of the cyclone aerator 2 of the present invention is as follows: During operation, the air inlet pipe 23 is connected to the fan 1 (such as the fan 1 described below). The fan 1 drives the airflow along the extension direction of the air inlet pipe 23, enters the guide channel from the airflow inlet, and exhales air to the surrounding areas from multiple airflow outlets 2421, forming a spiral upward airflow. After the airflow rises, a vacuum is generated at the bottom. Through negative pressure suction, the wastewater enters the cyclone aerator 2 and forms a soda-water mixture with the air, and then spirals upward. The rising soda-water mixture impacts the bubble generator 25 and causes it to rotate rapidly. When the soda-water mixture passes through, large bubbles are cut into small bubbles. Through the cutting of the bubble generator 25, the bubbles are continuously refined and become microbubbles that are evenly dissolved in the water, achieving the effect of oxygenation and aeration. The vortex formed at the same time further increases the hydraulic agitation and enhances the efficiency of the bacterial agglomeration in the wastewater.

[0037] According to the cyclone aerator 2 of the present invention, by setting the air inlet pipe 23 to extend into the cylinder 22 from the top of the cylinder 22 for aeration, the cyclone aerator 2 is formed into a structure in which the air inlet pipe 23 takes in air from the center of the cylinder 22, which can effectively avoid the tearing problem of the cylinder 22 and the air inlet pipe 23, and ensure the stability and force balance of the cyclone aerator 2 during operation. At the same time, by arranging multiple bubble cutting impellers 251 along the axial direction of the cylinder 22, the bubble refinement effect can be better, thereby further increasing the dissolved oxygen rate and enhancing the aeration effect.

[0038] According to some embodiments of the present invention, the angle between the central axis of the air flow outlet 2421 and the horizontal plane is in the range of 30 degrees to 90 degrees. For example, the angle between the central axis of the air flow outlet 2421 and the horizontal plane can be 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees or 90 degrees, so that the ejected air flow can easily rise.

[0039] refer to Figure 2 and Figure 4 In some embodiments of the present invention, the airflow guide 24 may include: a vertical pipe 241 and a plurality of guide pipes 242. Specifically, the vertical pipe 241 is fixedly connected to the air inlet pipe 23, and one end of the guide pipe 242 (for example Figure 1 The upper end of the guide tube 242 shown in FIG) is connected to and communicates with the vertical pipe 241, and the other end of the guide tube 242 (for example Figure 1 The lower end of the guide tube 242 shown in FIG2 extends to a position tangent to the inner circumferential wall of the cylinder 22. In the radial direction from the vertical tube 241 toward the cylinder 22, the guide tube 242 extends downwardly and obliquely along the circumference of the cylinder 22. The other end of the guide tube 242 forms an airflow outlet 2421, the central axis of which extends obliquely upward. In this way, air in the air intake pipe 23 can flow through the vertical tube 241 to the guide tube 242. The guide tube 242 guides the airflow flowing downward from the top of the air intake pipe 13 to flow along the circumferential direction of the cylinder 22, thereby forming a spiraling upward airflow within the cylinder 22. Thus, on the one hand, the gas flowing vertically downward in the vertical tube 241 can be guided toward the inner circumferential wall of the cylinder 22, and the gas ejected from the airflow outlet 2421 can be formed into a spirally ascending airflow. On the other hand, the downward oblique extension of the guide tube 242 can increase the upward travel of the airflow in the water to a certain extent, thereby achieving the purpose of sufficient dissolution.

[0040] Further, refer to Figure 2 The vertical pipe 241 is threadedly connected to the air intake pipe 23, and the threaded tightening direction of the vertical pipe 241 and the air intake pipe 23 is the same as the direction of the reaction force of the air outlet 2421 when the air flow is ejected. In this way, the connection stability of the vertical pipe 241 and the air intake pipe 23 can be further improved, and the loosening of the connection between the vertical pipe 241 and the air intake pipe 23 can be prevented during long-term operation.

[0041] In some embodiments, the lower end of the vertical tube 241 is fixed to the base 21, and the other end of the guide tube 242 is fixedly connected to the cylinder 22. For example, the lower end of the vertical tube 241 can be threadedly connected to the base 21, and the other end of the guide tube 242 can be welded to the inner wall of the cylinder 22. This ensures the connection stability of the airflow guide 24 and prevents the airflow guide 24 from shaking or even being damaged when the airflow is ejected from the airflow guide 24. At the same time, the airflow guide 24 can also serve to fix the lower end of the cylinder 22.

[0042] Furthermore, the distance between the lower end edge of the cylinder 22 and the lower end edge of the base 21 is in the range of 0.2m to 0.5m. For example, the distance between the lower end edge of the cylinder 22 and the lower end edge of the base 21 can be 0.2m, 0.3m, 0.4m or 0.5m. In this way, the lower end of the cylinder 22 can maintain a sufficient distance from the sludge settled to the bottom, thereby ensuring that there is enough space for the sewage to enter the cylinder 22 from the lower end of the cylinder 22 and mix with the gas.

[0043] According to some embodiments of the present invention, a plurality of bubble-cutting impellers 251 are rotatably mounted on the outside of the air inlet pipe 23, and the bubble-cutting impellers 251 are configured to rotate around their central axis under the impact of fluid from bottom to top. In this way, the bubble-cutting impellers 251 can rotate rapidly under the impact of the fluid force, cutting the rising large bubbles into tiny bubbles, thereby increasing the dissolved oxygen rate and achieving the aeration effect.

[0044] Further, refer to Figure 2 and Figure 3 The bubble cutting impeller 251 may include: a sleeve portion 2511 and a blade portion 2512. Specifically, the sleeve portion 2511 is sleeved on the air inlet pipe 23 and is threadedly connected to the air inlet pipe 23, thereby preventing the connection between the bubble cutting impeller 251 and the air inlet pipe 23 from loosening; the blade portion 2512 is rotatably sleeved on the radially outer side of the sleeve portion 2511, and is provided with a plurality of rotating blades. The plurality of rotating blades are spaced apart in the circumferential direction of the blade portion 2512, and the rotating blades extend radially outwardly along the blade portion 2512 and extend to the inner surface of the adjacent cylinder 22. In this way, the liquid can be fully stirred and the bubbles can be fully cut, further improving the dissolved oxygen rate.

[0045] Optionally, the blade portion 2512 may be provided with 6 to 12 blades, for example, the blade portion 2512 may be provided with 6, 8, 10 or 12 blades; the angle between each blade and the horizontal plane is in the range of 30 degrees to 60 degrees, and the angle between each blade and the horizontal plane is the same, which can facilitate the refinement of bubbles and improve the dissolved oxygen rate and aeration effect.

[0046] Furthermore, the threaded fastening direction of the sleeve portion 2511 and the intake pipe 23 is the same as the rotation direction of the blade portion 2512 under the impact of the fluid from bottom to top. In this way, the thrust generated by the fluid on the blade portion 2512 can tighten the sleeve portion 2511 and the intake pipe 23 to each other to prevent loosening.

[0047] In a specific example, the axial direction of the sleeve portion 2511 (eg Figure 2 Anti-loosening washers and anti-loosening nuts can be provided at both ends (in the upper and lower directions shown in the figure), and the anti-loosening nuts are threadedly connected to the intake pipe 23, which can reinforce and prevent the connection between the sleeve portion 2511 and the intake pipe 23 from loosening.

[0048] According to some embodiments of the present invention, the bubble generator 25 may further include: at least three bubble cutting impellers 251. That is, the number of the bubble cutting impellers 251 may be three, or four, five, six, or more. Among them, the bubble cutting impeller 251 located at the top of the cylinder 22 is arranged at the top of the cylinder 22, and the radial inner end of the top bubble cutting impeller 251 is fixed to the air inlet pipe 23 and the radial outer end is fixed to the cylinder 22. In this way, it can prevent the top bubble cutting impeller 251 from sliding upward out of the cylinder 22 due to the loosening of the connection between the sleeve portion 2511 and the air inlet pipe 23 during long-term operation. At the same time, it also has the effect of fixing the upper end of the cylinder 22 by using the top bubble cutting impeller 251.

[0049] Here, it should be noted that the radial outer end of the bubble cutting impeller 251 is fixed to the cylinder 22, which may refer to: the radial outer ends of multiple blades of the blade portion 2512 are fixed to the cylinder 22, for example, the radial outer ends of multiple blades are welded and fixed to the cylinder 22. At this time, the blade portion 2512 of the bubble cutting impeller 251 located at the top is stationary and does not rotate. When the soda-water mixture below flows through the top bubble cutting impeller 251, the bubble cutting impeller 251 cuts bubbles in a stationary state.

[0050] Of course, the radially outer end of the bubble-cutting impeller 251 is fixed to the cylinder 22, which can also mean that: the shaft sleeve portion 2511 of the topmost bubble-cutting impeller 251 is provided with a connecting portion extending radially outward to the inner circumferential wall of the cylinder 22, and the connecting portion is fixedly connected to the cylinder 22, for example, the connecting portion is welded to the cylinder 22. In this case, the topmost bubble-cutting impeller 251 can fix the upper end of the cylinder 22, and when the soda-water mixture below flows through the topmost bubble-cutting impeller 251, the bubble-cutting impeller 251 can rotate under the impact of the fluid, thereby further cutting bubbles.

[0051] Reference below Figures 1 to 4 A cyclone aeration device 100 according to a second aspect of the present invention will be described.

[0052] refer to Figure 1 The cyclone aeration device 100 according to the second aspect of the present invention comprises: a plurality of cyclone aerators 2 according to the first aspect of the present invention and a fan 1. Specifically, the fan 1 has an air outlet connected to an air inlet pipe 23. The air inlet pipes 23 of the plurality of cyclone aerators 2 can be connected in parallel. Thus, the fan 1 can drive air into the air inlet pipe 23, thereby providing a continuous airflow for the cyclone aerators 2. Furthermore, the parallel connection of the air inlet pipes 23 of the plurality of cyclone aerators 2 can further simplify the structure of the cyclone aerator 100 and facilitate maintenance.

[0053] For example Figure 1 As shown, the air inlet pipes 23 of multiple cyclone aerators 2 can share the same main air inlet pipe, and each air inlet pipe 23 is formed into a branch. One end of the main air inlet pipe is connected to the air outlet of the fan 1, and the air inlet pipes 23 of the multiple branches can be evenly spaced along the extension direction of the pipe body of the main air inlet pipe. The air inlet pipes 23 of the multiple branches are all connected to the main air inlet pipe. In this way, the air flow in the main air inlet pipe can flow to the air inlet pipes 23 of the multiple branches respectively under the drive of the fan 1, and then aerate the cylinder 22.
