Description

Technical Field

[0001] This utility model relates to the field of Fenton reaction towers, specifically a gas-lift counter-current vortex Fenton reaction tower. Background Technology

[0002] With societal development, people's demands for the environment are increasing. The purification and treatment of high-concentration, recalcitrant toxic and harmful organic pollutants such as phenols, pharmaceuticals, pesticides, dyes, and endocrine disruptors, which persist in aquatic environments and seriously threaten human health, has become increasingly urgent. Fenton oxidation is a widely used and highly efficient wastewater treatment technology. It utilizes the strong oxidizing properties of a mixed solution of hydrogen peroxide and ferrous ions, possessing the ability to efficiently remove recalcitrant organic pollutants. It is widely used in the treatment of wastewater from dyeing and printing, oily wastewater, phenolic wastewater, coking wastewater, nitrobenzene-containing wastewater, and diphenylamine wastewater.

[0003] In existing Fenton reactors, the mixing of wastewater and reagents is mostly achieved through air agitation or paddle agitation. The centrifugal force generated during the agitation process throws the wastewater against the inner wall of the reactor, resulting in poor mixing of wastewater and reagents, prolonging the mixing time, and increasing the overall mixing cost, thus reducing the overall practicality of the device.

[0004] In summary, the existing electric stirring method inside the Fenton reactor results in poor mixing of wastewater and reagents, prolongs the mixing time, and increases the overall mixing cost, thus reducing the overall practicality of the device. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an air-lift counter-impact vortex Fenton reactor to solve the technical problems that lead to poor mixing effect of wastewater and reagents due to electric stirring, which prolongs the mixing time of reagents and wastewater, and at the same time, the overall mixing cost is high, reducing the overall practicality of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gas-lift counter-current vortex Fenton reaction tower, comprising a tower body, wherein a hydrocyclone is connected to the top of the tower body via a support plate, and an array of guide plates are arranged around the inner wall of the tower body, wherein the guide plates themselves are inclined in the horizontal direction, and an aeration pipe is provided on the inner wall of the tower body, wherein the other end of the aeration pipe is located at the bottom of the guide plates.

[0007] By adopting the above technical solution, water flows from the hydrocyclone into the tower body. Under the swirling action of the hydrocyclone, the water entering the tower body rotates. At the same time, an array of guide plates are provided on the inner wall of the tower body. During the swirling process of the water, it will touch the guide plates on the inner wall, causing the water to rotate and flow in the tower body. This device reduces the use of electric drive components, lowers the overall mixing cost, and improves the overall practicality of the device.

[0008] The present invention is further configured such that the inner wall of the tower body is provided with an overflow port, and an overflow flange is connected through the tower body at one end of the overflow port.

[0009] Preferably, the overflow port allows excess water to be discharged to the outer wall of the tower body through the overflow flange, effectively preventing excessive water from affecting the tower's load-bearing capacity and further reducing the occurrence of accidents.

[0010] The present invention is further provided that the bottom of the tower body is provided with a vent flange, and a control switch is installed on the vent flange.

[0011] Preferably, the drain flange facilitates the drainage of water from inside the tower, while the control switch allows for easy opening and closing, further improving the overall practicality of the device.

[0012] The present invention is further configured such that an arc-shaped filter plate is provided on the inner wall of the tower body at the overflow port, and the two ends of the arc-shaped filter plate are in contact with the inner wall of the tower body.

[0013] Preferably, the filter plate prevents debris in the overflow water source from clogging the overflow outlet, thus preventing the overflow flange from working properly.

[0014] The present invention is further configured such that the inlet of the hydrocyclone is designed at a position tangent to the hydrocyclone itself.

[0015] Preferably, it facilitates changing the direction of the water entering the hydrocyclone, allowing the water to flow directly into the bottom of the tower.

[0016] The present invention is further configured such that the inner wall of the tower body is provided with a ring pipe, and the other end of the ring pipe is connected to the aeration pipe.

[0017] Preferably, during the swirling process, the water source is continuously tumbling within the tower through the cooperation of the aeration pipe and the ring pipe. This tumbling process makes the added chemicals more evenly mixed, improving the mixing effect of the water source and chemicals in the subsequent process.

[0018] The present invention is further configured such that one end of the overflow flange and the vent flange are respectively sealed at the connection point with the tower body.

[0019] Preferably, the sealing design effectively prevents leakage of the water source used in the reaction inside the tower and avoids external dust and impurities from entering the tower.

[0020] The present invention is further configured such that a climbing ladder is provided on the outer wall of the tower body, and a frame plate is provided at one end of the climbing ladder at the top of the tower body.

[0021] Preferably, a climbing ladder is provided to facilitate workers to climb to the top of the tower, making it easier for them to conduct regular inspections and maintenance of the tower's interior.

[0022] The present invention is further configured such that the outer wall of the guide plate is symmetrically provided with reinforcing ribs, and the other end of the reinforcing ribs is connected to the inner wall of the tower body.

[0023] Preferably, the reinforcing ribs improve the stability of the guide plate on the inner wall of the tower, preventing the guide plate from shifting at an angle under the impact of water sources over a long period of time.

[0024] The present invention is further configured such that the hydrocyclone itself is detachable.

[0025] Preferably, the detachable design facilitates subsequent maintenance and replacement of the hydrocyclone, effectively reducing the maintenance burden on subsequent staff.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model features a hydrocyclone installed at the top of the tower body. Water flows into the tower body through the hydrocyclone and is swirled by the hydrocyclone. Simultaneously, an array of guide plates is installed on the inner wall of the tower body. During the swirling process, the water touches the guide plates on the inner wall, causing the water to stagnate and flow in a rotating manner within the tower body. This device reduces the use of electrically driven components, lowers the overall mixing cost, and improves the overall practicality of the device.

[0028] 2. This utility model has an aeration pipe installed on the tower body, with one end of the aeration pipe connected to a ring pipe inside the tower body.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] First embodiment:

[0039] Please see Figures 1-5 The illustrated air-lift counter-current vortex Fenton reactor includes a tower body 1, an aeration pipe 3, a climbing ladder, a vortex mechanism, a sealing mechanism, and an overflow mechanism. A climbing ladder is installed on the outer wall of the tower body 1, with a support plate at one end of the ladder at the top of the tower body. This ladder facilitates workers' access to the top of the tower body 1 for regular inspection and maintenance. A hydrocyclone 4 is installed under the support plate, and the inlet of the hydrocyclone 4 is designed to be tangential to itself, facilitating the adjustment of the influent. The direction of the water in the hydrocyclone 4 causes the water to flow directly into the bottom tower body 1. At the same time, the hydrocyclone 4 causes the water entering the tower body 1 to rotate. An array of guide plates 2 are arranged around the inner wall of the tower body 1. The guide plates 2 are inclined in the horizontal direction. During the swirling process of the water, they will touch the guide plates 2 on the inner wall, causing the water to stop and rotate within the tower body 1. This device reduces the use of electric drive components, lowers the overall mixing cost, and improves the overall practicality of the device.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 2An overflow port 6 is provided on the inner wall of the tower body 1, and an overflow flange 5 is connected to the tower body through one end of the overflow port 6. Under the action of the overflow port 6, excess water inside will be discharged to the outer wall of the tower body 1 through the overflow flange 5, which effectively prevents the excessive water from affecting the load-bearing capacity of the tower body 1 and further reduces the occurrence of accidents. An arc-shaped filter plate is provided on the inner wall of the tower body 1 at the overflow port 6, and the two ends of the arc-shaped filter plate are in contact with the inner wall of the tower body 1. Under the action of the filter plate, it is prevented that the debris in the overflow water source will block the overflow port 6, thereby preventing the overflow flange 5 from working properly.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 A drain flange 7 is installed at the bottom of the tower body 1, and a control switch is installed on the drain flange 7. The drain flange 7 facilitates the drainage of water inside the tower body 1, and the control switch facilitates its opening and closing, further improving the overall practicality of the device.

[0042] Second embodiment:

[0043] Please see Figure 4 The Fenton reaction tower shown is similar in overall structure to that in Embodiment 1. The inner wall of the tower body 1 is surrounded by a ring pipe 8, and the other end of the ring pipe 8 is connected to the aeration pipe 3. During the swirling process, the water source is continuously tumbling inside the tower body 1 through the cooperation of the aeration pipe 3 and the ring pipe 8. During the tumbling process, the added reagents are mixed more evenly, which improves the mixing effect of the subsequent water source and reagents.

[0044] In practical operation, this invention works as follows: Water is connected to the top of the hydrocyclone 4, and the water flows into the tower body 1 under the action of the hydrocyclone 4. As the water flows out, the hydrocyclone 4 causes the water entering the tower body 1 to rotate. Simultaneously, a guide plate 2 is installed on the inner wall of the tower body, which is inclined horizontally. During the water's swirling flow, it touches the guide plate 2 on the inner wall, causing the water to stagnate and rotate within the tower body 1. This process reduces the use of electrically driven components, lowering the overall mixing cost. Furthermore, the aeration pipe 3 causes the rotating water to tumble within the tower body 1, resulting in more uniform mixing of the added chemicals and improving the subsequent mixing effect of the water and chemicals.

[0045] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
