Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a vortex catalytic reactor for ozone treatment of sewage. Background Art

[0002] At present, with the enhancement of environmental awareness and the improvement of sewage treatment standards, ozone oxidation technology is being used more and more widely in sewage treatment. Due to its strong oxidizing property, ozone can effectively remove harmful substances such as organic matter, inorganic matter, bacteria, viruses, etc. in wastewater and improve water quality. As one of the main equipment for ozone treatment of sewage, the ozone reaction tower has the advantages of high efficiency, broad spectrum, environmental protection and reliability, and plays an important role in sewage pretreatment, deep treatment, disinfection, decolorization and deodorization.

[0003] However, when a traditional ozone reaction tower treats sewage, sewage and ozone are mixed at the bottom of the tank. As the water level rises, the sewage mixed with ozone passes through the catalyst layer to decompose the impurities therein. However, simply relying on the automatic mixing of ozone and water fails to form effective doping, resulting in insufficient mixing of ozone and sewage, insufficient removal of harmful substances, or multiple treatments and low reaction efficiency, which affects the treatment effect. Summary of the invention

[0004] In order to reduce the impact on sewage treatment effects, the present application provides a vortex catalytic reactor for ozone treatment of sewage.

[0005] The present application provides a vortex catalytic reactor for ozone treatment of sewage, which adopts the following technical solution:

[0006] A vortex catalytic reactor for ozone treatment of sewage, comprising:

[0007] A catalytic tower having a catalytic chamber formed therein;

[0008] An ozone tube, disposed at the bottom of the catalytic tower, for supplying ozone;

[0009] A sewage pipe, arranged at the bottom of the catalytic tower, for supplying sewage;

[0010] A drain pipe, arranged at the top of the catalytic tower, for discharging the treated sewage;

[0011] An exhaust pipe, arranged at the top of the catalytic tower, for discharging exhaust gas;

[0012] A catalyst bed is arranged in the catalytic tower, dividing the catalytic chamber into a reaction zone and a decomposition zone, wherein the reaction zone is close to the ozone pipe and the sewage pipe;

[0013] The vortex mechanism comprises a rotating rod rotatably arranged in the catalytic tower, the rotating rod is located in the reaction zone, the rotating rod is provided with rotating blades, the catalytic tower is provided with a driving member, and the driving member is connected to the rotating rod.

[0014] By adopting the above technical scheme, when sewage is treated, sewage is first supplied to the catalytic tower through the sewage pipe, and ozone is supplied to the catalytic chamber through the ozone pipe. The ozone and sewage are initially mixed in the reaction chamber. As the driving member drives the rotating rod to rotate, the rotating blades disturb the sewage and form a vortex, so that the ozone and sewage are fully mixed and contacted, and then pass through the catalyst bed to produce a large number of hydroxyl free radicals, which directly mineralize or decompose the large molecules, long chains, and difficult-to-degrade pollutants in the wastewater into small molecules that are easily degradable organic matter, and then enter the maintenance tank through the drain pipe for continued decomposition until the wastewater is discharged after meeting the discharge standards; the tail gas enters the exhaust pipe and is then discharged into the atmosphere after treatment.

[0015] The vortex mechanism is set up to significantly enhance the mixing effect of sewage and ozone, so that the catalytic reaction can be completed in a shorter time. The setting of the catalyst bed makes the reaction process more orderly and efficient, and reduces the generation of by-products. Due to the efficient catalytic reaction, organic matter and microorganisms in sewage can be more effectively removed, thereby improving the treatment effect. By improving the reaction efficiency and treatment effect, energy consumption and pollutant emissions are reduced, which meets the requirements of energy conservation and environmental protection.

[0016] Optionally, the catalytic tower is further provided with a mixing mechanism, and the mixing mechanism comprises:

[0017] A first guide plate is arranged on the bottom wall of the catalytic tower, corresponding to the ozone tube, and is arranged obliquely;

[0018] The second guide plate is arranged on the bottom wall of the catalytic tower, corresponds to the sewage pipe, is inclined at one end away from the sewage pipe, and is close to one end of the first guide plate away from the ozone tube.

[0019] By adopting the above technical solution, when the ozone in the ozone tube is sprayed out, it contacts the first guide plate, and the first guide plate disperses and guides the ozone. The water sprayed out of the sewage pipe is guided and dispersed by the second guide plate, so that the ozone and sewage are offset, thereby improving the mixing effect and making the mixing of ozone and sewage more uniform.

[0020] Through the guidance of the first guide plate and the second guide plate, sewage and ozone form a more complex and effective mixed flow field in the catalytic tower, thereby improving the efficiency and treatment effect of the catalytic reaction; optimizing the flow field distribution in the catalytic tower, reducing unfavorable factors such as dead zones and vortices, and improving the overall performance of the reactor; due to the full mixing of sewage and ozone, the catalytic reaction can be carried out more thoroughly, thereby improving the sewage treatment effect; at the same time, the setting of the catalyst bed also further accelerates the reaction process and reduces energy consumption and pollutant emissions.

[0021] Optionally, the mixing mechanism further comprises:

[0022] A partition plate is arranged in the catalytic tower to divide the side of the reaction zone close to the ozone tube into a mixing zone, and is provided with a plurality of water outlets connected to the reaction zone. The water outlets are staggered with the first guide plate and the second guide plate.

[0023] By adopting the above technical solution, the partition plate provides a more concentrated mixing space for sewage and ozone, and controls the speed and direction of the mixed fluid entering the reaction zone through the water outlet holes thereon. This design helps to ensure that the sewage and ozone are fully mixed in the mixing zone and then flow into the reaction zone in a more uniform state.

[0024] The staggered layout of the water outlet and the first guide plate and the second guide plate avoids turbulence and energy loss that may be caused by direct impact of the fluid on the guide plate. At the same time, this staggered setting also helps to form a more complex flow field, so that the premixing of ozone and sewage can be carried out in a relatively stable space, further improving the mixing efficiency of sewage and ozone.

[0025] Since the sewage and ozone are fully mixed and pre-reacted in the mixing zone, the catalytic oxidation reaction can proceed more efficiently; this directly leads to a significant improvement in the treatment effect and a significant improvement in the effluent quality.

[0026] Optionally, the partition plate is slidably disposed on the catalytic tower and slides along the length direction of the catalytic tower, and the first guide plate and the second guide plate are both rotatably disposed on the catalytic tower;

[0027] The mixing mechanism further comprises two pressing plates arranged on the partition plate, and the two pressing plates correspond to the first guide plate and the second guide plate respectively; one end of the first guide plate and the second guide plate away from the ozone tube is located between the two pressing plates, and the two pressing plates press the first guide plate and the second guide plate so that the end of the first guide plate away from the ozone tube and the end of the second guide plate away from the ozone tube are close to each other;

[0028] The catalytic tower is also provided with a driving assembly, which is connected to the partition plate and is used to drive the partition plate to slide.

[0029] By adopting the above technical solution, during use, the position of the partition plate is first adjusted by the driving component to determine the size and position of the mixing zone, and the movement of the partition plate drives the pressure plate to slide, thereby adjusting the angles of the first guide plate and the second guide plate to form a more compact mixing space; when sewage and ozone enter the catalytic tower through the sewage pipe and the ozone pipe respectively, they will enter the mixing zone under the guidance of the guide plate and be more fully mixed under the squeezing action of the pressure plate; the mixed fluid then flows into the reaction zone through the water outlet hole on the partition plate and undergoes a catalytic oxidation reaction with the catalyst on the catalyst bed; at the same time, during the mixing process, the partition plate can be driven to slide by the driving component to achieve dynamic changes in the mixing zone, increase the impact angle and contact area of ​​ozone and sewage, and thereby increase the mixing of the two, thereby enhancing the mixing effect of the mixing zone, helping to form a more complex flow field structure, and enabling sewage and ozone to be more fully mixed and pre-reacted in the mixing zone; due to the improvement in mixing efficiency and the optimization of the flow field structure, the catalytic oxidation reaction can be carried out more efficiently, thereby improving the treatment effect and effluent water quality.

[0030] Optionally, the driving assembly comprises:

[0031] A cam, which is disposed on the rotating rod and has one end protruding from the rotating blade;

[0032] The slot plate is arranged on the partition plate and is provided with a receiving slot. One protruding end of the cam is located in the receiving slot and slides out of the receiving slot and abuts against the partition plate as the cam rotates.

[0033] By adopting the above technical solution, during use, the cam is set on the rotating rod and protrudes from the partition plate; at the same time, the slot plate is fixed on the partition plate and is provided with a receiving slot; when the rotating rod rotates, the cam will also rotate accordingly; as the cam rotates, its protruding end will slide out of the receiving slot and abut against the partition plate; this abutment will push the partition plate to slide along the length direction of the catalytic tower, thereby realizing dynamic adjustment of the position of the partition plate.

[0034] Through the rotation of the cam and the coordination of the slot plate, this solution can easily realize the dynamic adjustment of the position of the partition plate; due to the dynamic adjustment of the position of the partition plate, the mixing effect of sewage and ozone in the catalytic tower is significantly improved, which helps to accelerate the rate of the catalytic oxidation reaction, thereby improving the treatment efficiency; compared with traditional mixing methods that rely on high-intensity stirring or increasing fluid pressure, this solution achieves a more efficient mixing effect by optimizing the mixing process and adjusting the position of the partition plate, thereby reducing energy consumption.

[0035] Optionally, the driving assembly further includes:

[0036] A return spring is arranged on the bottom wall of the catalytic tower and connected to the partition plate, and is used for driving the partition plate to move away from the bottom of the catalytic tower.

[0037] By adopting the above technical solution, during use, when the position of the partition plate needs to be adjusted, the cam in the driving assembly will rotate and push the partition plate to move along the length direction of the catalytic tower; when the cam rotates to a certain position, its protruding end will slide out of the groove plate and abut against the partition plate, thereby pushing the partition plate to move; at this time, the return spring will be compressed and store elastic potential energy; when the cam rotates to another position, its protruding end will leave the partition plate, at which time the return spring will release the elastic potential energy and drive the partition plate to automatically return to the initial position or a predetermined position.

[0038] The introduction of the return spring enables the partition plate to automatically return to its initial position, reducing reliance on manual operation and improving the degree of automation of the equipment; by adjusting the position of the partition plate, the mixing effect of sewage and ozone in the catalytic tower can be optimized; the automatic return function of the return spring ensures that the partition plate can be accurately and stably moved to the specified position, thereby ensuring the stability and consistency of the mixing effect; the elastic effect of the return spring can reduce the energy loss of the drive component in the process of moving the partition plate; compared with the traditional mechanical transmission method, this solution reduces energy consumption while maintaining efficient mixing; the setting of the return spring enhances the reliability of the equipment; during the operation of the equipment, even if some fault or abnormal situation causes the partition plate to shift, the return spring can quickly reset it to the initial position or a safe position, thereby avoiding equipment damage or safety accidents.

[0039] Optionally, an adjustment component is provided on the partition plate, and the adjustment component includes:

[0040] The adjusting plate is rotatably disposed on the partition plate and is provided with a plurality of blocking holes, wherein the blocking holes correspond to the water outlet holes, and the plurality of blocking holes are connected with some of the water outlet holes. As the adjusting plate rotates, the blocking holes are connected with different water outlet holes.

[0041] By adopting the above technical solution, when it is necessary to adjust the water flow rate or flow direction, it is only necessary to rotate the adjustment plate. As the adjustment plate rotates, the blocking hole will be connected to different water outlet holes, thereby changing the water flow rate and flow direction.

[0042] By adjusting the outlet water flow rate and direction, the flow field structure in the catalytic tower can be optimized, so that the mixed fluid is more evenly distributed on the catalyst bed, thereby improving the efficiency of the catalytic oxidation reaction; precise flow and flow direction regulation helps to reduce unnecessary energy consumption losses; compared with the traditional method of relying on external equipment to control flow, this solution reduces energy consumption while maintaining high-efficiency catalysis; the design of this solution enables the equipment to be flexibly adjusted according to different treatment requirements; whether it is necessary to change the outlet water flow rate or flow direction, it can be easily achieved by adjusting the components, thereby enhancing the adaptability and flexibility of the equipment.

[0043] Optionally, the adjustment component includes:

[0044] A slide plate slides in the receiving groove, and its initial position is located in the middle of the receiving groove, and is connected to the adjustment plate;

[0045] A rotating sleeve, disposed on the adjusting plate and rotatably connected to the partition plate;

[0046] The torsion member is arranged on the partition plate and connected with the rotating sleeve, and is used for driving the rotating sleeve to rotate so that the slide plate is located in the middle of the accommodating groove.

[0047] By adopting the above technical solution, during use, as the cam rotates, the cam abuts against the slide and drives the slide to slide, so that the slide drives the adjusting plate to overcome the torsional force of the torsion piece and rotate. When the cam is separated from the slide, the torsion piece releases the accumulated elastic force and drives the slide to reset. The slide drives the adjusting plate to rotate in the opposite direction. The rotation of the adjusting plate realizes the switching of the connection between the blocking hole and the water outlet hole, thereby changing the water outlet position and changing the flow direction and distribution of the mixed fluid in the catalytic tower. This adjustment helps to optimize the flow field structure and improve the efficiency of the catalytic oxidation reaction. At the same time, the design of the slide and the slot plate also reduces the resistance and energy loss of the fluid during the flow process.

[0048] Optionally, the rotating blade is located at one end of the rotating rod close to the partition plate.

[0049] By adopting the above technical solution, during use, when the rotating rod rotates, the rotating blades located at one end thereof close to the partition plate will drive the surrounding fluid to rotate and mix; since the rotating blades are located close to the partition plate, their stirring action will more directly act on the fluid near the partition plate, thereby achieving enhanced stirring of the fluid in this area; at the same time, the interaction between the rotating blades and the regulating assembly will further promote the mixing and dispersion of the fluid.

[0050] By concentrating the rotating blades at one end of the rotating rod close to the partition plate, enhanced stirring is achieved in a specific area, thereby improving the mixing efficiency; this design allows the fluid to be mixed more evenly in the catalytic tower, helping to increase the speed and efficiency of the catalytic oxidation reaction.

[0051] The interaction between the rotating blades and the partition plates and the regulating components thereon helps to optimize the flow field structure; by adjusting the position and shape of the rotating blades, the flow direction and speed of the fluid in the catalytic tower can be further controlled, thereby achieving more efficient mixing and dispersion.

[0052] Optionally, the vortex mechanism further comprises a guide vane spirally arranged on the inner wall of the catalytic tower, one end of the guide vane extends to the rotating vane, and the other end extends to the catalyst bed.

[0053] By adopting the above technical solution, during use, when the rotating rod rotates, the rotating blades will drive the surrounding fluid to rotate and mix; at this time, the guide vanes will play a key guiding role, guiding the fluid from the rotating blades to the catalyst bed; because the guide vanes are spirally arranged, the fluid will form vortices during the flow process, thereby increasing the contact area and contact time between the fluid and the catalyst, and improving the efficiency of the catalytic oxidation reaction.

[0054] By introducing guide vanes, a more direct and efficient fluid guiding structure is formed, thereby improving the strength and stability of the vortex; this design makes the flow of fluid in the catalytic tower more orderly and controllable, which helps to improve the speed and efficiency of the catalytic oxidation reaction; the guide vanes can guide the fluid to be more evenly distributed on the catalyst bed, thereby avoiding excessive accumulation or loss of fluid in local areas; this optimized fluid distribution helps to improve the utilization rate and reaction efficiency of the catalyst; because the design of the guide vanes can more effectively utilize the fluid power generated by the rotating vanes, it can reduce energy consumption while maintaining efficient mixing and vortex effects; this design reduces unnecessary energy consumption losses, making the equipment more energy-efficient during operation.

[0055] In summary, the present application includes at least one of the following beneficial technical effects:

[0056] 1. The vortex mechanism significantly enhances the mixing effect of sewage and ozone, so that the catalytic reaction can be completed in a shorter time. The setting of the catalyst bed makes the reaction process more orderly and efficient, reducing the generation of by-products. Due to the efficient catalytic reaction, organic matter and microorganisms in sewage can be removed more effectively, thereby improving the treatment effect. By improving the reaction efficiency and treatment effect, energy consumption and pollutant emissions are reduced, meeting the requirements of energy conservation and environmental protection.

[0057] 2. By adjusting the outlet water flow rate and flow direction, the flow field structure in the catalytic tower can be optimized, so that the mixed fluid is more evenly distributed on the catalyst bed, thereby improving the efficiency of the catalytic oxidation reaction; precise flow rate and flow direction regulation helps to reduce unnecessary energy loss; compared with the traditional method of relying on external equipment to control the flow rate, this solution reduces energy consumption while maintaining efficient catalysis;

[0058] 3. By introducing the guide vanes, a more direct and efficient fluid guiding structure is formed, thereby improving the strength and stability of the vortex; this design makes the flow of the fluid in the catalytic tower more orderly and controllable, which helps to improve the speed and efficiency of the catalytic oxidation reaction; the guide vanes can guide the fluid to be more evenly distributed on the catalyst bed, thereby avoiding excessive accumulation or loss of fluid in local areas; this optimized fluid distribution helps to improve the utilization rate and reaction efficiency of the catalyst; because the design of the guide vanes can more effectively utilize the fluid power generated by the rotating vanes, it can reduce energy consumption while maintaining efficient mixing and vortex effects; this design reduces unnecessary energy consumption losses, making the equipment more energy-efficient during operation.

The ozone contacts the first guide plate 810, and the sewage contacts the second guide plate 820, so that the ozone and the sewage are close to each other and collide with each other to mix; the mixed sewage and ozone enter the reaction zone 111 through the water outlet 831, and the drive motor is started, and the drive motor drives the transmission shaft 750 rotates, and the transmission shaft 750 drives the rotating rod 710 and the rotating blade 720 to rotate, so as to disturb and mix the sewage and ozone, and form a vortex through the guide blade 740, close to the catalyst bed 600, to generate a large number of hydroxyl free radicals, and directly mineralize or decompose the large molecules, long chains, and difficult-to-degrade pollutants in the wastewater into small molecules and easily degradable organic matter, and then enter the maintenance tank through the drain pipe 400 to continue decomposition until the wastewater is discharged after meeting the discharge standards; the exhaust gas enters the exhaust pipe 500, and then is discharged into the atmosphere after treatment.

[0078] During the decomposition process, the cam 851 rotates with the rotating rod 710, so that the cam 851 repeatedly completes the process of entering and exiting the accommodating groove 854, so that the partition plate 830 slides back and forth along the length direction of the catalytic tower 100, and the partition plate 830 drives the first guide plate 810 and the second guide plate 820 to move closer to or away from each other through the pressure plate 840, thereby increasing the disturbance in the mixing zone 113; at the same time, the cam 851 drives the adjustment plate 861 to rotate through the slide plate 862, so that part of the water outlet holes 831 are blocked and part of the water outlet holes 831 are opened, so that the water outlet position of the mixing zone 113 changes, thereby changing the flow field in the catalytic tower 100, so that ozone and sewage are fully mixed, which is convenient for decomposing sewage.

[0079] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
