Description

Technical Field

[0001] The invention relates to the technical field of ozone catalytic oxidation towers, in particular 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 catalysts. Its core lies in reducing the reaction activation energy and improving the reaction selectivity and efficiency. It is widely used in environmental governance, energy conversion and chemical synthesis. Catalytic oxidation reactions are often used in sewage treatment systems. Catalysts are used to enhance the decomposition of ozone to accelerate the chemical reaction between pollutants and oxidants in wastewater, thereby removing pollutants from the water.

[0003] The catalytic oxidation tower is the core equipment of the ozone catalytic oxidation system. It is mainly composed of a shell, a water inlet pipe, an air inlet pipe, a catalyst layer and a water outlet pipe. Ozone and sewage are introduced into the shell and mixed. 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, the patent with patent authorization announcement number CN213253827U discloses an ozone catalytic oxidation system, including a reactor body, a top cover is installed on the top of the reactor body, and a bottom cover is fixed to the bottom of the reactor body, an exhaust pipe is installed on the top of the top cover, and a water inlet pipe is fixed to the bottom end of the bottom cover, and the end of the water inlet pipe away from the bottom cover is connected to an ozone generator through a pipeline, and fixing rings are installed at both ends of the reactor body, and a catalyst layer is connected to the position of the reactor body between the two fixing rings, and partitions are installed on the side of the two fixing rings away from the catalyst layer. The above-mentioned device can quickly fix the partition on the fixing ring through the cooperation of structures such as a clamping ring, a clamping groove, a limit block and a limit groove, and can quickly remove it by rotating the partition, thereby realizing rapid assembly of the partition, simple and convenient operation, without the aid of additional tools, and improving work efficiency.

[0005] However, the above ozone catalytic oxidation system still has certain defects when used: When the catalytic oxidation tower in the above-mentioned ozone catalytic oxidation system is in use, since the catalyst layer cannot move, the fixed and stacked catalyst particles form a continuous static bed, and the gas and liquid phases diffuse only through limited pores, resulting in a decrease in the effective contact area, which directly reduces the probability of chemical reactions, thereby reducing the degradation efficiency of organic pollutants, resulting in inefficient use of the catalyst, and also resulting in a reduction in the service life of the catalyst and an increase in the maintenance frequency.

[0009] Furthermore, a fixed seat is fixedly connected to the top of the rotating column, a rotating block is fixedly connected to the surface of the fixed seat, the outer wall of the rotating block is rotatably connected to the chassis, a threaded column is fixedly connected to the surface of the chassis, a connecting tube is fixedly connected to the upper surface of the middle part of the flexible base, a connecting plate is fixedly connected to the middle part of the inner wall of the connecting tube, the connecting plate is fitted with the surface of the chassis, a fixed tube is fixedly connected to the middle part of the closing cover, a fixing plate is fixedly connected to the bottom of the inner wall of the fixed tube, the fixing plate is fitted with the surface of the connecting plate, a connecting sleeve is slidably connected inside the fixed tube, a threaded groove corresponding to the position of the threaded column is opened on the bottom surface of the connecting sleeve, the bottom surface of the connecting sleeve is fitted with the surface of the fixing plate, and the fixed tube is located inside the connecting tube.

[0010] Furthermore, a fixing belt is fixedly connected to the surface of the closing cover, and a plurality of clamping grooves are arranged between the fixing belt and the surface of the closing cover, and an air bag is slidably connected in each clamping groove.

[0011] Furthermore, two symmetrically arranged limit blocks are fixedly connected to the surface of the airbag, the fixing belt is located between the two limit blocks on the same airbag, and the side of the limit block away from the fixing belt is arranged as a bevel.

[0012] Furthermore, a slider is fixedly connected to one end of the moving rod away from the moving ball, a plurality of fixed blocks are fixedly connected to the inner wall of the catalytic oxidation tower, and a slide groove corresponding to the position of the slider is opened on one side of the fixed block.

[0013] Furthermore, an elastic band is fixedly connected to the surface of the flexible base.

[0014] Furthermore, a handle is fixedly connected to the top of the connecting sleeve.

[0015] Furthermore, the lifting track is a wavy track setting, the moving balls are arranged equidistantly 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 that is consistent with the rotation direction of the motor drive is smaller.

[0016] Furthermore, the top edge of the support block is provided with a rounded corner.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) This type of ozone catalytic oxidation system helps to evenly distribute catalyst particles, promote turbulent mixing of gas and liquid phases in the catalyst layer, effectively increase the area of ​​the three-phase contact surface, and the dynamically disturbed catalyst bed can prevent particle agglomeration and pore blockage, maintain high mass transfer efficiency, and improve the use efficiency of the catalyst and the degradation efficiency of organic pollutants; (2) Periodic mechanical vibration can also peel off the passivation layer on the catalyst surface, 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 effectively prevent particle agglomeration and pore clogging, thereby reducing the maintenance frequency of the system; (3) The closed cover can form a relatively closed space, which helps prevent the catalyst particles from accidentally falling or being washed away by water during the operation of the system, prevents the loss of catalyst, and ensures that the catalyst particles are always located at the predetermined position; the baffle can prevent the sewage from flowing away from the gap between the closed cover and the inner wall of the catalytic oxidation tower, ensuring that all sewage entering the system can fully contact the catalyst layer, thereby improving the coverage and uniformity of the reaction; (4) The airbag can drive the closing cover to float, leaving enough space for the catalyst particles, ensuring that the catalyst particles under the closing cover will not be subjected to excessive pressure during the flow of sewage, thereby maintaining their loose state, which is conducive to full contact and reaction between sewage and catalyst particles; (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 elasticity of the elastic band, it can help the flexible base return to its original shape and avoid 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 subjected to external pressure (such as water flow impact or the thrust of the support block), reducing the risk of damage caused by excessive deformation; (6) By utilizing the non-equilateral triangle setting of the support block and the mutual cooperation of the lifting track, when the support block pushes the flexible base up and down, the flexible base will produce a slight tilt change under the action of different slopes. This tilt change will drive the catalyst particles to rotate at a small angle, so that the catalyst particles can more fully contact the gas-liquid two phases, enhance the dynamic stirring effect, increase the reaction contact area, and continuously peel off the passivation layer on the catalyst surface 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, and further improving the mass transfer efficiency, accelerating the degradation process of organic pollutants; (7) Since the moving balls are arranged equidistantly along the wave-shaped lifting track, when a moving ball moves to the crest of the lifting track, its two adjacent moving balls will move to the trough, thereby expanding the height difference between the tops of the two support blocks as much as possible, thereby increasing the deformation of the flexible base, thereby enhancing the dynamic stirring effect. The equidistantly arranged moving balls and the alternating up and down movement mode ensure the uniform distribution of the catalyst particles and avoid excessive concentration in local areas; (8) The rounded corner design enables the support block to distribute pressure more evenly when pushing the flexible base, avoiding local stress concentration, reducing damage to the flexible base, reducing wear between the support block 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 to the flexible base. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figures 1 to 12 A catalytic ozone oxidation system comprises a catalytic oxidation tower 1, wherein a support plate 2 is fixedly connected to the inner wall of the catalytic oxidation tower 1, a flexible base 3 is installed on the upper surface of the support plate 2, a plurality of fixed rods 4 are fixedly connected to the bottom of the support plate 2, a fixed sleeve 5 is fixedly connected to the bottom of the fixed rod 4, a motor 6 is fixedly connected to the fixed sleeve 5, a rotating shaft 7 is fixedly connected to the output shaft of the motor 6, a top end of the rotating shaft 7 penetrates the fixed sleeve 5 and the top of the support plate 2, and a rotating column 8 is fixedly connected to the top end of the rotating shaft 7, 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 supporting block 13 is fixedly connected to the outer wall of the moving rod 12, and a top end of the supporting block 13 is in contact with the bottom surface of the flexible base 3.

[0022] The ozone catalytic oxidation system of the present invention, when treating sewage, places the catalyst particles on the flexible base 3, and the surface of the flexible base 3 is provided with a plurality of water-permeable holes, the diameter of the water-permeable holes is smaller than the particle size of the catalyst particles, and then the motor 6 drives the rotating shaft 7 and the rotating column 8 to rotate, and under the restriction of the lifting track 9, the moving ball 11 is lifted and lowered along the lifting track 9, thereby driving the moving rod 12 and the supporting block 13 thereon to move up and down. Since the supporting block 13 is in contact with the bottom surface of the flexible base 3, the up and down movement of the supporting block 13 will drive the part of the flexible base 3 in contact with it to move up and down, and as the multiple supporting blocks 13 drive the various areas on the flexible base 3 to fluctuate up and down, thereby bringing The catalyst particles on the dynamic flexible base 3 rise and fall accordingly, thereby realizing dynamic stirring of the catalyst layer. This dynamic stirring helps to evenly distribute the catalyst particles, promote turbulent mixing of the gas-liquid two-phase in the catalyst layer, and effectively increase 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, and improve the utilization efficiency of the catalyst and the degradation efficiency of organic pollutants. At the same time, periodic mechanical vibration can also peel off the passivation layer on the catalyst surface, evenly distribute the catalyst particles, and continuously activate the catalytic active sites, thereby improving the oxidation efficiency of the catalyst and extending the service life of the catalyst. It can also effectively prevent particle agglomeration and pore blockage and reduce the maintenance frequency of the system.

[0023] As a preferred technical solution of the present invention, a closing cover 17 is fixedly connected to the outside of the flexible base 3 , a baffle 18 is fixedly connected to the top outer wall of the closing cover 17 , and the baffle 18 is fixedly connected to the inner wall of the catalytic oxidation tower 1 .

[0024] Specifically, the closing cover 17 is provided with the same water-permeable holes as the flexible base 3, and the closing cover 17 can form a relatively closed space, which helps to prevent the catalyst particles from accidentally falling or being washed away by water 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 18 can prevent the sewage from flowing away from the gap between the closing 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, thereby improving the coverage and uniformity of the reaction.

[0025] As a preferred technical solution of the present invention, a rotating block is fixedly connected to the top of the rotating column 8, and a fixed seat 20 is rotatably connected to the outer wall of the rotating block. A chassis 21 is fixedly connected to the top of the fixed seat 20, and a threaded column 22 is fixedly connected to the upper surface of the chassis 21. A connecting tube 28 is fixedly connected to the middle surface of the flexible base 3, and a connecting piece 29 is fixedly connected to the middle of the inner wall of the connecting tube 28, and the connecting piece 29 is fitted with the surface of the chassis 21. A fixed tube 26 is fixedly connected to the middle of the closing cover 17, and a fixing piece 27 is fixedly connected to the bottom of the inner wall of the fixing tube 26, and the fixing piece 27 is fitted with the surface of the connecting piece 29. A connecting sleeve 23 is slidably connected inside the fixed tube 26, and a threaded groove 24 corresponding to the position of the threaded column 22 is opened on the bottom surface of the connecting sleeve 23, and the bottom surface of the connecting sleeve 23 is fitted with the surface of the fixing piece 27, and the fixed tube 26 is located inside the connecting tube 28.

[0026] Specifically, during normal use, the connecting sleeve 23 and the chassis 21 will clamp the fixing plate 27 and the connecting plate 29, thereby sealing the area between the closing 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, unscrew the connecting sleeve 23, and then pull the fixing tube 26 out of the connecting tube 28. At this time, an opening will appear between the closing cover 17 and the flexible base 3, and the catalyst can be replaced and maintained from 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 easily make changes through this opening to adapt to different treatment needs or optimize the treatment effect. This flexibility enables the system to cope with a variety of sewage types and treatment requirements, improving its scope of application and practicality.

[0027] As a preferred technical solution of the present invention, a fixing belt 30 is fixedly connected to the surface of the closing cover 17, and a plurality of snap-in grooves 31 are provided between the fixing belt 30 and the surface of the closing cover 17, and an airbag 32 is slidably connected in each snap-in groove 31.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] As a preferred technical solution of the present invention, an elastic band 19 is fixedly connected to the surface of the flexible base 3 .

[0034] 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.

[0035] As a preferred technical solution of the present invention, a handle 25 is fixedly connected to the top of the connecting sleeve 23 .

[0036] Specifically, when the closing cover 17 needs to be installed or removed, the staff can easily rotate the connecting sleeve 23 by holding the handle 25. By rotating the handle 25, the connecting sleeve 23 can be screwed out of or screwed into the fixing tube 26, thereby achieving quick disassembly and assembly. The design of the handle 25 provides a better gripping point, reduces the risk of hand slippage during operation, and improves the safety of operation.

[0037] As a preferred technical solution of the present invention, the lifting track 9 is a wavy track setting, the moving balls 11 are arranged equidistantly 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.

[0038] 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 tilt change under the action of different slopes. This tilt change will drive the catalyst particles to rotate at a small angle, so that the catalyst particles can more fully contact the gas-liquid two phases, enhance the dynamic stirring effect, increase the reaction contact area, and continuously peel off the passivation layer on the catalyst surface to re-expose the active sites, so that the catalyst can still maintain a high oxidation efficiency after long-term operation, significantly improve the long-term stability of the system, and further improve the mass transfer efficiency, and accelerate the degradation process of organic pollutants; at the same time, because the moving balls 11 are arranged equidistantly along the wavy lifting track 9, when a moving ball 11 moves to the crest of the lifting track 9, its two adjacent moving balls 11 will move to the trough, so that the height difference between the tops of the two support blocks 13 is expanded as much as possible, thereby increasing the deformation of the flexible base 3, thereby enhancing the dynamic stirring effect, and the equidistantly arranged moving balls 11 and the alternating up and down movement mode ensure the uniform distribution of catalyst particles and avoid excessive concentration in local areas.

[0039] As a preferred technical solution of the present invention, the top edge of the support block 13 is provided with a rounded corner.

[0040] 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 to the flexible base 3.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
