Description

Technical Field

[0001] The present invention relates to the technical field of ozone catalytic oxidation towers, and specifically to an ozone catalytic oxidation system. Background Art

[0002] Catalytic oxidation technology is a green chemical process that accelerates the oxidation reaction process by introducing a catalyst. Its core lies in reducing the reaction activation energy, improving the reaction selectivity and efficiency, and is widely used in environmental governance, energy conversion, chemical synthesis and other fields. Catalytic oxidation reactions are often applied in sewage treatment systems. By using a catalyst to enhance the decomposition of ozone, the chemical reaction between pollutants and oxidants in wastewater is accelerated, thereby removing pollutants in water.

[0003] The catalytic oxidation tower is the core equipment of the ozone catalytic oxidation system, mainly composed of a shell, an inlet water pipeline, an inlet gas pipeline, a catalyst layer and an outlet water pipeline. By introducing ozone and sewage into the shell for mixing, when the mixed liquid flows through the catalyst layer, ozone will react with the sewage to purify the sewage.

[0004] As in the prior art, a patent with the patent authorization announcement number CN213253827U discloses an ozone catalytic oxidation system, including a reactor body. A top cover is installed at the top of the reactor body, and a bottom cover is fixed at the bottom of the reactor body. An exhaust pipe is installed at the top end of the top cover, and an inlet water pipe is fixed at the bottom end of the bottom cover. The end of the inlet water pipe away from the bottom cover is connected to an ozone generator through a pipeline. Fixed rings are installed at both ends inside the reactor body, and a catalyst layer is connected at a position between the two fixed rings inside the reactor body. Partition plates are installed on one side of the two fixed rings away from the catalyst layer. Through the cooperation of structures such as snap rings, card slots, limit blocks and limit grooves, the partition plates can be quickly fixed on the fixed rings, and at the same time, the partition plates can be quickly removed by rotating them, thus realizing the quick assembly of the partition plates. The operation is simple and convenient, without the need to rely on additional tools, improving work efficiency.

[0005] However, the above ozone catalytic oxidation system still has certain defects when in use:

[0006] When the catalytic oxidation tower in the above ozone catalytic oxidation system is in use, since the catalyst layer cannot move, the fixed and piled catalyst particles form a continuous static bed layer, and the gas-liquid two-phase diffuses only through limited pores, resulting in a decrease in the effective contact area, directly reducing the probability of chemical reactions, thereby reducing the degradation efficiency of organic pollutants, leading to low utilization efficiency of the catalyst, and also reducing the service life of the catalyst and increasing the maintenance frequency. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides an ozone catalytic oxidation system to improve the utilization efficiency of the catalyst.

[0008] To achieve the above object, the present invention provides the following technical solution: An ozone catalytic oxidation system includes a catalytic oxidation tower. The inner wall of the catalytic oxidation tower is fixedly connected with a support disk. The upper surface of the support disk is provided with a flexible base. The bottom of the support disk is fixedly connected with a plurality of fixing rods. The bottom of the fixing rods is fixedly connected with fixing sleeves.

A moving rod is fixedly connected to the outer wall of each moving ball. A moving groove corresponding to the position of the moving rod is provided on the outer wall of the rotating column. A support block is fixedly connected to the outer wall of the moving rod. The top of the support block is in contact with the bottom surface of the flexible base.

[0009] Further, a sealing cover is fixedly connected to the top of the flexible base. A flow-blocking belt is fixedly connected to the outer wall of the top of the sealing cover. The flow-blocking belt is fixedly connected to the inner wall of the catalytic oxidation tower.

[0010] Further, a fixing seat is fixedly connected to the top of the rotating column. A rotating block is fixedly connected to the surface of the fixing seat. The outer wall of the rotating block is rotatably connected with a chassis. A threaded column is fixedly connected to the surface of the chassis. A connecting pipe is fixedly connected to the upper surface of the middle part of the flexible base. A connecting piece is fixedly connected to the middle part of the inner wall of the connecting pipe. The connecting piece is in contact with the surface of the chassis. A fixing pipe is fixedly connected to the middle part of the sealing cover. A fixing piece is fixedly connected to the bottom of the inner wall of the fixing pipe. The fixing piece is in contact with the surface of the connecting piece. A connecting sleeve is slidably connected inside the fixing pipe. A threaded groove corresponding to the position of the threaded column is provided on the bottom surface of the connecting sleeve. The bottom surface of the connecting sleeve is in contact with the surface of the fixing piece. The fixing pipe is located inside the connecting pipe.

[0011] Further, a fixing belt is fixedly connected to the surface of the sealing cover. A plurality of clamping grooves are provided between the fixing belt and the surface of the sealing cover. An airbag is slidably connected inside each clamping groove.

[0012] Further, two symmetrically arranged limiting blocks are fixedly connected to the surface of the airbag. The fixing belt is located between the two limiting blocks on the same airbag. The side of the limiting block away from the fixing belt is provided with an inclined edge.

[0013] Further, one end of the moving rod away from the moving ball is fixedly connected with a slider. A plurality of fixing blocks are fixedly connected to the inner wall of the catalytic oxidation tower. A sliding groove corresponding to the position of the slider is provided on one side of the fixing block.

[0014] Further, an elastic band is fixedly connected to the surface of the flexible base.

[0015] Further, a handle is fixedly connected to the top of the connecting sleeve.

[0016] Furthermore, the lifting track is arranged as a wavy track, the moving balls are arranged at equal intervals along the lifting track, the cross-section of the support block is a non-equilateral triangle, and the slope of the side of the support block consistent with the rotation direction driven by the motor is smaller.

[0017] Furthermore, the top edge of the support block is provided with a rounded corner.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This ozone catalytic oxidation system helps to evenly distribute the catalyst particles, promotes the turbulent mixing of gas-liquid two phases in the catalyst layer, effectively increases the area of the three-phase contact surface. The dynamically disturbed catalyst bed can prevent particle agglomeration and pore blockage, maintain high mass transfer efficiency, improve the utilization efficiency of the catalyst and the degradation efficiency of organic pollutants;

[0020] (2) The periodic mechanical vibration can also strip the passivation layer on the surface of the catalyst, evenly distribute the catalyst particles, continuously activate the catalytic active sites, improve the oxidation efficiency of the catalyst, extend the service life of the catalyst, and can also effectively prevent particle agglomeration and pore blockage, reducing the maintenance frequency of the system;

[0021] (3) The closed cover can form a relatively closed space, which helps to prevent the catalyst particles from accidentally falling or being washed away by the water flow during the operation of the system, prevent the loss of the catalyst, and ensure that the catalyst particles are always located at the predetermined position; the baffle belt can prevent the sewage from flowing away through the gap between the closed cover and the inner wall of the catalytic oxidation tower, ensuring that all the sewage entering the system can fully contact with the catalyst layer, improving the coverage and uniformity of the reaction;

[0022] (4) The airbag can drive the closed cover to float, thus leaving enough space for the catalyst particles, ensuring that during the flow of the sewage, the catalyst particles under the closed cover will not be subjected to excessive pressure, so as to keep them in a loose state, which is beneficial to the full contact and reaction between the sewage and the catalyst particles;

[0023] (5) The elastic band can maintain the deformation performance of the flexible base. When the support block moves up and down, the flexible base will deform accordingly. Due to the high elastic characteristics of the elastic band, it can help the flexible base to return to its original state, avoiding permanent deformation or relaxation after long-term use; the elastic band not only improves the deformation recovery ability of the flexible base, but also enhances its mechanical strength, which makes the flexible base more stable when bearing external pressures (such as water flow impact or the thrust of the support block), reducing the risk of damage caused by excessive deformation;

[0024] (6) By utilizing the non-equilateral triangular arrangement of the support blocks and the mutual cooperation of the lifting tracks, when the support blocks push the flexible base up and down, the flexible base will generate slight inclination changes under the action of different slopes. This inclination change will drive the catalyst particles to rotate at a small angle, enabling the catalyst particles to come into contact with the gas-liquid two-phase more fully, enhancing the dynamic stirring effect, increasing the reaction contact area, continuously stripping the passivation layer on the surface of the catalyst, re-exposing the active sites, enabling the catalyst to maintain a high oxidation efficiency even after long-term operation, significantly improving the long-term stability of the system, further enhancing the mass transfer efficiency, and accelerating the degradation process of organic pollutants;

[0025] (7) Since the moving balls are arranged equidistantly along the wavy lifting track, when a certain moving ball moves to the peak of the lifting track, its two adjacent moving balls will move to the trough, thereby maximizing the height difference between the tops of the two support blocks, further increasing the deformation of the flexible base, enhancing the dynamic stirring effect. The equidistant arrangement of the moving balls and the alternating up-and-down movement mode ensure the uniform distribution of the catalyst particles and avoid over-concentration in local areas;

[0026] (8) The rounded corner design enables the support blocks to distribute pressure more evenly when pushing the flexible base, avoiding local stress concentration, reducing damage to the flexible base, lowering the wear between the support blocks and the flexible base, and extending the service life of the flexible base. Especially in the case of long-term operation and frequent up-and-down movement, it effectively prevents excessive wear and damage of the flexible base. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0041] Please refer to Figures 1 to 12, an ozone catalytic oxidation system, including a catalytic oxidation tower 1, the inner wall of the catalytic oxidation tower 1 is fixedly connected with a support plate 2, the upper surface of the support plate 2 is provided with a flexible base 3, the bottom of the support plate 2 is fixedly connected with a plurality of fixing rods 4, the bottom of the fixing rods 4 is fixedly connected with a fixing sleeve 5, a motor 6 is fixedly connected inside the fixing sleeve 5, the output shaft of the motor 6 is fixedly connected with a rotating shaft 7, the top of the rotating shaft 7 penetrates through the fixing sleeve 5 and the top of the support plate 2, and the top of the rotating shaft 7 is fixedly connected with a rotating column 8. A lifting track 9 is provided on the outer wall of the rotating column 8, a plurality of moving balls 11 are slidably connected in the lifting track 9, a moving rod 12 is fixedly connected to the outer wall of each moving ball 11, a moving groove 10 corresponding to the position of the moving rod 12 is provided on the outer wall of the rotating column 8, a support block 13 is fixedly connected to the outer wall of the moving rod 12, and the top of the support block 13 is in contact with the bottom surface of the flexible base 3.

[0042] In the ozone catalytic oxidation system of the present invention, when treating sewage, catalyst particles are placed on the flexible base 3. A plurality of water permeable holes are provided on the surface of the flexible base 3, and the diameter of the water permeable holes is smaller than the particle size of the catalyst particles. Subsequently, the motor 6 drives the rotating shaft 7 and the rotating column 8 to rotate. Under the restriction of the lifting track 9, the moving balls 11 will move up and down along the lifting track 9, thereby driving the moving rods 12 and the support blocks 13 thereon to move up and down. Since the support blocks 13 are in contact with the bottom surface of the flexible base 3, the up and down movement of the support blocks 13 will drive the part of the flexible base 3 in contact with them to move up and down. As the plurality of support blocks 13 drive each area on the flexible base 3 to fluctuate up and down, the catalyst particles on the flexible base 3 are driven to rise and fall accordingly, thereby realizing the dynamic stirring of the catalyst layer. This dynamic stirring helps to evenly distribute the catalyst particles, promotes the turbulent mixing of the gas-liquid two phases in the catalyst layer, effectively increases the area of the three-phase contact surface, and the dynamically disturbed catalyst bed layer can prevent particle agglomeration and pore blockage, maintain high mass transfer efficiency, improve the use efficiency of the catalyst and the degradation efficiency of organic pollutants; at the same time, the periodic mechanical vibration can also strip the passivation layer on the surface of the catalyst, evenly distribute the catalyst particles, continuously activate the catalytic active sites, improve the oxidation efficiency of the catalyst, extend the service life of the catalyst, and can also effectively prevent particle agglomeration and pore blockage, reduce the maintenance frequency of the system.

[0043] As a preferred technical solution of the present invention, a closed cover 17 is fixedly connected to the outside of the flexible base 3, and a baffle belt 18 is fixedly connected to the outer wall of the top of the closed cover 17. The baffle belt 18 is fixedly connected to the inner wall of the catalytic oxidation tower 1.

[0044] Specifically, the closed cover 17 is provided with water-permeable holes identical to those of the flexible base 3. The closed cover 17 can form a relatively enclosed space, which helps prevent catalyst particles from accidentally falling or being washed away by the water flow during the operation of the system, preventing catalyst loss and ensuring that the catalyst particles are always located at the predetermined position. The baffle strip 18 can prevent sewage from flowing away through the gap between the closed cover 17 and the inner wall of the catalytic oxidation tower 1, ensuring that all sewage entering the system can fully contact the catalyst layer, improving the coverage rate and uniformity of the reaction.

[0045] As a preferred technical solution of the present invention, a rotating block is fixedly connected to the top of the rotating column 8. The outer wall of the rotating block is rotatably connected to a fixed seat 20. The top of the fixed seat 20 is fixedly connected to a chassis 21. A threaded column 22 is fixedly connected to the upper surface of the chassis 21. The middle surface of the flexible base 3 is fixedly connected to a connecting pipe 28. The middle of the inner wall of the connecting pipe 28 is fixedly connected to a connecting piece 29. The connecting piece 29 is in contact with the surface of the chassis 21. The middle of the closed cover 17 is fixedly connected to a fixed pipe 26. The bottom of the inner wall of the fixed pipe 26 is fixedly connected to a fixed piece 27. The fixed piece 27 is in contact with the surface of the connecting piece 29. A connecting sleeve 23 is slidably connected in the fixed pipe 26. A threaded groove 24 corresponding to the position of the threaded column 22 is provided on the bottom surface of the connecting sleeve 23. The bottom surface of the connecting sleeve 23 is in contact with the surface of the fixed piece 27. The fixed pipe 26 is located inside the connecting pipe 28.

[0046] Specifically, during normal use, the connecting sleeve 23 and the chassis 21 will clamp the fixed piece 27 and the connecting piece 29, thereby realizing the sealing of the area between the closed cover 17 and the flexible base 3, further ensuring that the catalyst will not be lost. When the catalyst needs to be replaced or regenerated, the connecting sleeve 23 is unscrewed, and then the fixed pipe 26 is pulled out from the connecting pipe 28. At this time, an opening will appear between the closed cover 17 and the flexible base 3, and the catalyst can be replaced and maintained through this opening. This design not only ensures the stability and safety of the catalyst during the operation of the system, but also greatly facilitates the replacement and maintenance of the catalyst. This design also improves the flexibility and scalability of the system. When it is necessary to adjust the type, quantity or distribution of the catalyst, the operator can conveniently make changes through this opening to adapt to different treatment requirements or optimize the treatment effect. This flexibility enables the system to handle various types of sewage and treatment requirements, improving its scope of application and practicality.

[0047] As a preferred technical solution of the present invention, a fixed belt 30 is fixedly connected to the surface of the closed cover 17. A plurality of clamping grooves 31 are provided between the fixed belt 30 and the surface of the closed cover 17. An airbag 32 is slidably connected in each clamping groove 31.

[0048] Specifically, when sewage passes through, the airbag 32 can drive the closing cover 17 to float, thereby leaving enough space for the catalyst particles, ensuring that the catalyst particles under the closing cover 17 will not be subjected to excessive pressure during the flow of sewage, thereby maintaining their loose state, which is conducive to sufficient contact and reaction between the sewage and the catalyst particles.

[0049] As a preferred technical solution of the present invention, two symmetrically arranged limit blocks 33 are fixedly connected to the surface of the airbag 32, the fixing belt 30 is located between the two limit blocks 33 on the same airbag 32, and the side of the limit block 33 away from the fixing belt 30 is set as a bevel.

[0050] Specifically, the limit block 33 can prevent the airbag 32 from slipping out of the snap-in groove 31, ensuring the stability of the airbag 32 during use; when installing the airbag 32, the beveled edge of the limit block 33 can facilitate the staff to squeeze the airbag 32 into the snap-in groove 31, bringing convenience to the staff.

[0051] As a preferred technical solution of the present invention, the end of the moving rod 12 away from the moving ball 11 is fixedly connected to a slider 16, and a plurality of fixed blocks 14 are fixedly connected to the inner wall of the catalytic oxidation tower 1. A slide groove 15 corresponding to the position of the slider 16 is opened on one side of the fixed block 14.

[0052] Specifically, the cooperation between the slider 16 and the slide groove 15 limits the lateral movement of the moving rod 12, ensuring that during the rotation of the rotating column 8, the moving rod 12 and the supporting block 13 thereon can move up and down along a predetermined path, avoiding system instability caused by shaking or deviation.

[0053] As a preferred technical solution of the present invention, an elastic band 19 is fixedly connected to the surface of the flexible base 3 .

[0054] Specifically, the elastic band 19 can maintain the deformation performance of the flexible base 3. When the support block 13 moves up and down, the flexible base 3 will deform accordingly. Due to the high elasticity of the elastic band 19, it can help the flexible base 3 return to its original state and avoid permanent deformation or relaxation after long-term use. The elastic band 19 not only improves the deformation recovery ability of the flexible base 3, but also enhances its mechanical strength, which makes the flexible base 3 more stable when subjected to external pressure (such as water flow impact or thrust of the support block 13), reducing the risk of damage caused by excessive deformation.

[0055] As a preferred technical solution of the present invention, a handle 25 is fixedly connected to the top of the connecting sleeve 23 .

[0056] Specifically, when it is necessary to install or disassemble the closed cover 17, the staff can easily rotate the connecting sleeve 23 by holding the grip 25. By rotating the grip 25, the connecting sleeve 23 can be screwed out or into the fixed tube 26, thus achieving quick disassembly and assembly. The design of the grip 25 provides a better gripping point, reduces the risk of hand slipping during operation, and improves the safety of operation.

[0057] As a preferred technical solution of the present invention, the lifting track 9 is arranged as a wavy track, the moving balls 11 are arranged at equal intervals along the lifting track 9, the cross-section of the support block 13 is a non-equilateral triangle, and the slope of the side of the support block 13 that is consistent with the driving rotation direction of the motor 6 is smaller.

[0058] Specifically, by utilizing the non-equilateral triangle setting of the support block 13 and the mutual cooperation of the lifting track 9, when the support block 13 pushes the flexible base 3 to move up and down, the flexible base 3 will produce a slight inclination change under the action of different slopes. This inclination change will drive the catalyst particles to rotate at a small angle, enabling the catalyst particles to more fully contact the gas-liquid two-phase, enhancing the dynamic stirring effect, increasing the reaction contact area, and continuously peeling off the passivation layer on the surface of the catalyst to re-expose the active sites, so that the catalyst can still maintain a high oxidation efficiency after long-term operation, significantly improving the long-term stability of the system, further improving the mass transfer efficiency, and accelerating the degradation process of organic pollutants; at the same time, since the moving balls 11 are arranged at equal intervals along the wavy lifting track 9, when a certain moving ball 11 moves to the peak of the lifting track 9, its two adjacent moving balls 11 will move to the trough, thereby maximizing the height difference between the tops of the two support blocks 13, further increasing the deformation of the flexible base 3, thus enhancing the dynamic stirring effect. The equally spaced moving balls 11 and the alternating up-and-down movement mode ensure the uniform distribution of the catalyst particles and avoid excessive concentration in local areas.

[0059] As a preferred technical solution of the present invention, the top edge of the support block 13 is provided with a rounded corner.

[0060] Specifically, the rounded corner design enables the support block 13 to distribute pressure more evenly when pushing the flexible base 3, avoiding local stress concentration, reducing damage to the flexible base 3, reducing wear between the support block 13 and the flexible base 3, and extending the service life of the flexible base 3. Especially in the case of long-term operation and frequent up-and-down movement, it effectively prevents excessive wear and damage of the flexible base 3.

[0061] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
