For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] See also Figure 1-8 The present invention provides a technical solution: a sewage purifier with a catalytic device, including a sewage treatment tank 1, the sewage treatment tank 1 includes a tank body 11 and three guide walls 12, the three guide walls 12 are fixedly arranged in the tank body 11, the three guide walls 12 and the tank body 11 are existing equipment well known in the art, and their specific working principles and internal structures are not introduced in detail. Two brackets 5 are fixedly arranged on the left side of the tank body 11 and on the corresponding guide walls 12, and a catalytic unit 2 for improving the sewage treatment effect is arranged between the two brackets 5. The two brackets 5 are used to fix the catalytic unit 2 in the tank body 11, so that the catalytic unit 2 is fully in contact with the sewage in the tank body 11, thereby improving the decomposition efficiency of the pollutants, and a uniform distribution unit 3 for improving the catalytic effect of the catalytic unit 2 is arranged at the bottom of the tank body 11. The uniform distribution unit 3 can ensure that the outside air is evenly distributed before entering the catalytic unit 2, thereby optimizing the efficiency of the catalytic reaction.

[0031] Specifically, the catalytic unit 2 includes an outer cylinder 21, an inner cylinder 22, a bottom plate 23, a plurality of first connecting seats 24, a movable cover plate 25, a plurality of second connecting seats 26 and an air inlet pipe 27. The inner cylinder 22 and the outer cylinder 21 are both open cylinders, and a plurality of small holes are provided on the inner cylinder 22 and the outer cylinder 21. These small holes are used to realize the circulation and exchange of gas. The inner cylinder 22 and the outer cylinder 21 are hollow cylindrical structures. The inner cylinder 22 is located on the inner side of the outer cylinder 21. The bottom plate 23 is fixedly arranged at the bottom of the outer cylinder 21 and the inner cylinder 22. A certain interval is maintained between the outer cylinder 22 and the outer cylinder 21 to form an annular cavity. The annular cavity between the outer cylinder 21 and the inner cylinder 22 is filled with a replaceable catalyst 28. This design allows the catalyst 28 to be easily replaced after reaching a certain service life or the efficiency is reduced, thereby maintaining the processing capacity and efficiency of the system. The outer cylinder 21 is fixedly arranged between the two brackets 5 to ensure the stability of the outer cylinder 21 during use. A plurality of first connecting seats 24 are fixedly arranged on the outer wall of the outer cylinder 21, and a plurality of second connecting seats 26 are fixedly arranged on the outer edge of the movable cover plate 25. The first connecting seats 24 correspond to the second connecting seats 26, and they are connected by bolts. Each first connecting seat 24 and its corresponding second connecting seat 26 are precisely aligned in spatial position, so that the bolts can pass through the first connecting seat 24 and the second connecting seat 26, and are tightened by threads, so that the outer cylinder 21 and the movable cover plate 25 are firmly connected together, ensuring the stability and sealing of the structure. This connection method is convenient for disassembly and assembly, so that the catalyst 28 can be replaced. One end of the intake pipe 27 It is fixedly connected to the movable cover plate 25, and the air inlet pipe 27 is communicated with the inner tube 22 to form a gas introduction channel, so that the gas can flow from the air inlet pipe 27 into and through the inner tube 22, ensuring that the gas can flow from the air inlet pipe 27 into and through the inner tube 22 without obstacles. The gas enters the inner tube 22 from the air inlet pipe 27, passes through the small hole, and then passes through the gap of the catalyst 28, so that the gas forms dense bubbles and passes through the small hole of the outer tube 21. During the gas passing process, it contacts with the catalyst 28 and sewage over a large area, thereby accelerating the decomposition rate of pollutants.

[0032] Specifically, the uniform distribution unit 3 includes two sliders 31, a support shell 32, a rotating shaft 33, a first motor 34, a first gear 35, a second gear 36, a driving shaft 37 and a plurality of diverter plates 38. An annular groove is provided at the bottom of the pool body 11, and the two sliders 31 are slidably connected to the annular groove. The support shell 32 is fixedly arranged at the top of the two sliders 31. The support shell 32 can rotate in an annular groove through the two sliders 31. The rotating shaft 33 is connected to the bottom of the pool body 11, and the top of the rotating shaft 33 is fixedly connected to the outer bottom of the supporting shell 32. The sealed bearing can ensure that the sewage will not leak out of the pool body 11 while the rotating shaft 33 rotates stably, thereby ensuring good sealing. The first motor 34 is fixedly arranged at the outer bottom of the pool body 11, and the first gear 35 is fixedly connected to the outer bottom of the supporting shell 32. 35 is fixedly arranged at the driving end of the first motor 34, the second gear 36 is fixedly arranged at the bottom end of the rotating shaft 33, and the second gear 36 is meshed with the first gear 35, the driving shaft 37 is connected to the top and the bottom of the supporting shell 32, and the driving shaft 37 is connected to the bottom plate 23 through a sealed bearing. When the first motor 34 is running, its power is transmitted to the rotating shaft 33 through the first gear 35 and the second gear 36, so that the rotating shaft 33 further drives the driving shaft 37 to rotate, and a plurality of diverter plates 38 are fixedly arranged on the driving shaft 37. The diverter plate 38 is a circular structure, and the surface of the diverter plate 38 is uniformly provided with continuously alternating protrusions 38-1 and recesses 38-2 with its center as the reference point, and the diameter of the diverter plate 38 is smaller than the diameter of the inner cylinder 22 to ensure the normal passage of airflow.

[0033] The splitter plate 38 is used to disperse and optimize the gas transported by the intake pipe 27, so that the gas is in uniform contact with each part of the catalyst 28, and the catalytic effect and service life of the catalytic unit 2 are improved. When the gas flows through the splitter plate 38 having the recessed portion 38-2 and the raised portion 38-1, the recessed portion 38-2 promotes the formation of gas turbulence, helps to break the laminar flow state, enhances the mixing of gas molecules, and improves the uniformity of the contact between the gas and the catalyst 28; the recessed portion 38-2 reduces the channel for the straight flow of the gas, prevents the gas from repeatedly contacting a certain part of the catalyst 28, and ensures the integrity and effect of the catalytic reaction. At the same time, the raised portion 38-1 increases the residence time of the gas in the catalytic unit 2 by blocking the gas and changing its flow direction, causing the gas molecules to stir when passing through, and these movements help the gas molecules to fully contact with the subsequent catalyst 28, thereby improving the rate and efficiency of the catalytic reaction.

[0034] At the same time, on the basis of the above, the driving shaft 37 of the uniform distribution unit 3 can drive the diverter plate 38 to rotate. This rotation can continuously change the direction and speed of the gas flow, thereby forming a dynamic flow pattern inside the catalytic unit 2. This pattern helps to break the static distribution of the gas in the catalyst 28 layer, prevent the formation of a fixed flow channel, and ensure that the gas is in uniform contact with each section of the catalyst 28; the rotational motion of the diverter plate 38 causes the gas to be continuously agitated when passing through the catalytic unit 2. This agitation not only enhances the turbulence of the gas, but also promotes the collision frequency between the gas molecules and the surface of the catalyst 28, thereby increasing the rate of the catalytic reaction; the diverter plate 38 can break up the airflow when rotating, causing it to disperse. Such a flow path increases the residence time of the gas molecules in the catalytic unit 2, helps to increase the contact time between the gas and the catalyst 28, thereby improving the conversion rate of the reaction, and the airflow will be continuously cut and reorganized. This continuous airflow breaking effect helps the airflow to be in as uniform contact with various parts of the catalyst 28 as possible.

[0035] Specifically, a cleaning unit 4 for cleaning the surface of the catalytic unit 2 is disposed on the supporting shell 32 .

[0036] The blockage of the small holes may result in restricted gas flow, reduce the contact area between the gas and the catalyst 28, thereby reducing the catalytic efficiency and even causing failure of the catalytic unit 2. By real-time cleaning of the cleaning unit 4, it is possible to ensure that the small holes on the outer cylinder 21 are always unobstructed, ensure the smooth passage of gas, and maintain the efficient operation of the catalytic unit 2.

[0037] Specifically, the cleaning unit 4 includes two cleaning roller brushes 41 , which are connected to the top and bottom of the support shell 32 via sealed bearings, and the two cleaning roller brushes 41 are respectively located on the left and right sides of the driving shaft 37 .

[0038] The two cleaning roller brushes 41 inside the cleaning unit 4 are in contact with the surface of the outer cylinder 21 , and the two cleaning roller brushes 41 and the uniform distribution unit 3 share a power source.

[0039] Specifically, the cleaning unit 4 also includes a second motor 42, a first sprocket 43, two second sprockets 44 and a chain 45. A receiving groove is opened inside the rotating shaft 33. The second motor 42 is fixedly arranged in the receiving groove of the rotating shaft 33. The receiving groove is used for the installation of the second motor 42. The driving shaft 37 is connected to the top and bottom of the supporting shell 32 through sealed bearings. The driving end of the second motor 42 is fixedly connected to one end of the driving shaft 37. The first sprocket 43 is fixedly arranged on the driving shaft 37. The two second sprockets 44 are respectively fixedly arranged on the two cleaning roller brushes 41. The two second sprockets 44 are respectively located on the left and right sides of the first sprocket 43. The first sprocket 43 and the two second sprockets 44 are connected by a chain 45.

[0040] In the design in which the uniform distribution unit 3 and the cleaning unit 4 are opened synchronously, the cleaning unit 4 further limits the connection mode of the driving shaft 37 .

[0041] In the case where the cleaning unit 4 is not introduced, the driving shaft 37 and the supporting shell 32 are fixedly connected. This connection ensures that the first motor 34 can directly drive the driving shaft 37 to rotate, thereby achieving uniform distribution of gas in the catalytic unit 2.

[0042] After the introduction of the cleaning unit 4, the connection method is further limited, that is, the drive shaft 37 and the support shell 32 are rotatably connected through a sealed bearing. This design allows the second motor 42 to be connected to the drive shaft 37, thereby forcing the drive shaft 37 to rotate, and the rotation direction of the rotating shaft 33 is the same as that of the driving end of the second motor 42, and the self-rotation action of the cleaning roller brush 41 is introduced.

[0043] The self-rotation action of the cleaning unit 4 enables the two cleaning roller brushes 41 to form self-rotation while rotating around the outer cylinder 21, thereby improving the uniformity and effectiveness of the contact between the cleaning roller brushes 41 and the surface of the outer cylinder 21 and enhancing the cleaning effect. The self-rotation increases the contact frequency between the cleaning roller brushes 41 and the surface of the outer cylinder 21, making the cleaning more thorough and less likely to leave dead corners. The friction force generated by the self-rotation helps to remove deposits at a deeper level, because the self-rotation enables the cleaning roller brushes 41 to act on the surface of the outer cylinder 21 at different angles and forces, thereby effectively destroying and removing stubborn dirt. The self-rotation action can also prevent the cleaning roller brushes 41 from uneven wear due to long-term single-direction friction, thereby extending the service life of the cleaning roller brushes 41.

[0044] Specifically, the protruding portion 38 - 1 of the splitter plate 38 is provided with a guide hole 38 - 3 .

[0045] The guide hole 38-3 can cause local acceleration of the gas when passing through the protrusion 38-1. This acceleration effect helps to enhance the turbulence of the gas, thereby increasing the collision frequency between the gas molecules and the surface of the catalyst 28 and promoting the catalytic reaction; secondly, the existence of the guide hole 38-3 makes the flow path of the gas on the diverter plate 38 more complicated. This complex flow pattern helps to prevent the gas from forming a fixed flow channel in the catalytic unit 2, ensuring that the gas can be in uniform contact with every part of the catalyst 28, thereby improving the catalytic efficiency; thirdly, the guide hole 38-3 can also effectively disperse the gas flow, reduce the dead zone of the gas in the catalytic unit 2, and improve the utilization efficiency of the catalyst 28; finally, the design of the guide hole 38-3 enables the diverter plate 38 to more effectively break up the airflow when rotating, thereby increasing the residence time of the gas molecules in the catalytic unit 2, which not only helps to increase the contact time between the gas and the catalyst 28, but also can improve the conversion rate of the reaction, while ensuring the maximum uniform contact between the airflow and each part of the catalyst 28, thereby improving the performance of the catalytic unit 2 as a whole.

[0046] Specifically, multiple diverter plates 38 are arranged along the rotating shaft 33 in a rotationally staggered manner, wherein each subsequent diverter plate 38 is rotated 20 degrees around the rotating shaft 33 relative to the previous diverter plate 38, ensuring that the protrusion 38-1 of the subsequent diverter plate 38 and the recessed portion of the previous diverter plate 38 are located at the same position, ensuring that when the fluid passes through, the protrusion 38-1 and the guide hole 38-3 of each diverter plate 38 can interact with each other in a staggered manner, further optimizing the distribution and flow characteristics of the fluid, so that the fluid can be more evenly dispersed and mixed when passing through the catalytic unit 2, reducing the flow dead zone, and improving the contact efficiency between the fluid and the catalyst 28.

[0047] Specifically, the diameter of the first sprocket 43 is greater than the diameter of the second sprocket 44 .

[0048] The stability of the first sprocket 43 and the second sprocket 44 during the transmission process is improved.

[0049] Specifically, the sewage treatment tank 1 further includes an inlet pipe 13 and an outlet pipe 14 , one end of the inlet pipe 13 is fixedly connected to the left side of the tank body 11 , and one end of the outlet pipe 14 is fixedly connected to the right side of the tank body 11 .

[0050] Working principle: First, the staff passes the external gas into the air inlet pipe 27 of the catalytic unit 2, and the gas then enters the catalyst 28 layer through the small holes in the inner tube 22. In this process, the uniform distribution unit 3 and the cleaning unit 4 are started synchronously to achieve effective dispersion of the gas and continuous cleaning of the small holes on the surface of the outer tube 21. The diverter plate 38 in the uniform distribution unit 3 is designed with a recessed portion 38-2 and a raised portion 38-1. When the gas flows through these diverter plates 38, the recessed portion 38-2 promotes the formation of gas turbulence, which not only helps to break the laminar state of the gas, but also enhances the mixing of gas molecules, thereby improving the uniformity of the contact between the gas and the catalyst 28. At the same time, the recessed portion 38-2 reduces the channel for the straight-line flow of the gas, avoids repeated contact between the gas and a certain part of the catalyst 28, and ensures the integrity and efficiency of the catalytic reaction.

[0051] At the same time, the role of the protrusion 38-1 is to block the gas and change its flow direction, which increases the residence time of the gas in the catalytic unit 2 and causes the gas molecules to agitate when passing through. These agitations help the gas molecules to fully contact with various parts of the catalyst layer 28, thereby improving the rate and efficiency of the catalytic reaction.

[0052] The driving shaft 37 of the uniform distribution unit 3 is driven by the second motor 42, and the second motor 42 drives the diverter plate 38 to rotate continuously through the driving shaft 37, and this rotation constantly changes the direction and speed of the gas flow, thereby forming a dynamic flow pattern inside the catalytic unit 2. This pattern effectively breaks the static distribution of the gas in the catalyst 28 layer, prevents the formation of fixed flow channels, and ensures that the gas can contact every part of the catalyst 28 evenly.

[0053] While the uniform distribution unit 3 is working, the cleaning unit 4 is also working synchronously. The second motor 42 in the cleaning unit 4 drives the driving shaft 37 to rotate, and the rotation of the driving shaft 37 drives the diverter plate 38, and also drives the cleaning roller brush 41 to rotate around the surface of the outer cylinder 21 through the chain 45 transmission system to achieve the cleaning of the small holes. The self-rotation of the cleaning roller brush 41 is synchronously driven by the first sprocket 43 on the driving shaft 37 through the chain 45 to drive the two second sprockets 44, and then drives the cleaning roller brush 41 to rotate. This self-rotation is combined with the rotation around the outer cylinder 21, which greatly improves the cleaning effect, ensures the unobstructed small holes of the outer cylinder 21, and maintains the efficient operation of the catalytic unit 2. The working principle of the whole system ensures the uniformity of gas distribution and the cleanliness of the catalytic unit 2, thereby improving the efficiency of sewage purification and the service life of the catalytic unit 2.
