[0032] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application.

[0033] As shown in FIG. 1 and FIG. 2 , in one embodiment, a packing structure 10 is provided, comprising a reaction body 100 and a catalyst member 200. The reaction body 100 is provided with a reaction channel 110. The catalyst member 200 is installed in the reaction channel 110, and the catalyst member 200 is provided with a connecting cavity 210; along the extension direction of the reaction channel 110 (the direction shown by C in FIG. 1 ), the two end faces of the catalyst member 200 are provided with a first connecting hole 220 connected with the connecting cavity 210, and the catalyst member 200 is used to generate a catalytic oxidation reaction with the treated medium.

[0034] When the packing structure 10 in the above embodiment is used, the catalyst component 200 is correspondingly installed in the reaction channel 110 to assemble the packing structure 10. When the treated medium needs to be subjected to catalytic oxidation treatment, the treated medium is input from one end of the reaction channel 110, so that the treated medium is fully contacted with the catalyst component 200 during the flow in the reaction channel 110 and a catalytic oxidation reaction occurs, and then the organic matter in the treated medium is oxidized and decomposed into harmless substances such as water and carbon dioxide, thereby achieving the purpose of purification. Compared with the catalytic oxidation method in the prior art, the packing structure 10 in the present application has at least the following advantages: 1. The catalyst component 200 is set as a porous hollow structure, so that the contact area between the treated medium and the catalyst component 200 is increased during the flow of the treated medium in the reaction channel 110, ensuring that the treated medium can fully react with the catalyst component 200 and increase the reaction efficiency. 2. When the flow rate and pressure of the treated medium entering the reaction channel 110 are high, the catalytic component 200 can block and buffer the treated medium, so that the flow rate and pressure of the treated medium are reduced, ensuring that there is sufficient contact reaction time between the treated medium and the catalytic component 200, thereby improving the treatment effect and reliability of the packing structure 10. 3. The mechanical components of the packing structure 10 are simple, and there are no dead corners inside the reaction channel 110, which will not cause secondary pollution, thereby improving the treatment effect and reliability of the packing structure 10. 4. The packing structure 10 is a multi-stage structure. Different types of catalytic components 200 can be selected according to the different treated media, and the number of packing structures 10 can be increased or decreased according to actual use requirements. It is easy to operate and occupies a small area. 5. When conducting a catalytic oxidation reaction, there is no need to add other agents, no solid waste is generated, and the initial design investment cost and later maintenance cost of the packing structure 10 are reduced.

[0035] The catalyst 200 may be rotatably mounted in the reaction channel 110 or may be fixedly mounted in the reaction channel 110. The catalyst 200 may be a heterogeneous catalyst. Specifically in the present embodiment, the catalyst 200 may be configured as a catalyst cage, which may be made of solid metal, metal oxide, metal supported on a carrier, or metal oxide supported on a carrier. The treated medium may be wastewater, air, industrial waste gas or other fluid medium requiring catalytic oxidation treatment.

[0036] The reaction body 100 may be configured as a reaction cylinder, a reaction tube or other reaction structures.

[0037] As shown in FIG. 1 , FIG. 2 and FIG. 3 , further, the packing structure 10 further includes a mounting member 300 and a first stopper 400. The mounting member 300 is mounted in the reaction channel 110 along the extension direction of the reaction channel 110 and is spaced apart from the inner side wall of the reaction channel 110. The first stopper 400 is mounted between the outer side wall of the mounting member 300 and the inner side wall of the reaction channel 110 and is used to limit the movement of the mounting member 300 in the reaction channel 110 along the radial direction of the reaction channel 110 (the direction shown by D in FIG. 1 ). There is at least one catalytic member 200, and each catalytic member 200 is mounted on the mounting member 300 along the extension direction of the reaction channel 110. In this way, the catalytic member 200 can rotate in the reaction channel 110 to stir the treated medium in the reaction channel 110, ensuring that the treated medium can fully contact with the catalytic member 200, and the contact time between the treated medium and the catalytic member 200 is increased, thereby improving the treatment effect and reliability of the packing structure 10. In addition, by increasing the number of catalyst elements 200, the contact area and contact time between the processed medium and the catalyst elements 200 during the flow in the reaction channel 110 are increased, ensuring that the processed medium can fully react with the catalyst elements 200 and increasing the reaction efficiency.

[0038] The catalytic element 200 can be mounted on the mounting element 300 by snap-fitting, plugging, screwing, welding or other connection methods. The mounting element 300 can be set as a mounting shaft, a mounting rod, or other mounting structures. The first limiter 400 can be set as a limiter bracket, a limiter seat, a radial fixed blade or other limiter structure. The first limiter 400 can be made of corrosion-resistant stainless steel, which is beautiful as a whole and easy to maintain and clean later. The number of the first limiters 400 can be flexibly adjusted according to the actual needs of use.

[0039] As shown in FIG. 1 and FIG. 3 , optionally, each catalyst component 200 is gap-matched with the reaction channel 110, and the outer side wall of each catalyst component 200 is provided with a second connecting hole 230 corresponding to the connecting cavity 210 of each catalyst component 200. In this way, the treated medium can also enter the connecting cavity 210 from the outer side wall of the catalyst component 200 through the second connecting hole 230, so that the contact area between the treated medium and the catalyst component 200 during the flow in the reaction channel 110 is increased, ensuring that the treated medium can fully react with the catalyst component 200, thereby increasing the reaction efficiency. In addition, the catalyst component 200 is gap-matched with the reaction channel 110, ensuring that the catalyst component 200 can rotate smoothly in the reaction channel 110, and also enabling the catalyst component 200 to intercept large foreign matter in the treated medium, ensuring that large foreign matter in the treated medium will not directly enter the catalytic oxidation reaction area, thereby improving the reliability of the packing structure 10.

[0040] Specifically in this embodiment, the first connecting hole 220 can be set as a rectangular hole or a square hole; the number of the first connecting hole 220 is at least one, and it is evenly distributed on the two end surfaces of the catalyst 200. The shape and size of the second connecting hole 230 are the same as those of the first connecting hole 220; the number of the second connecting hole 230 is at least one, and it is evenly distributed on the outer wall of the catalyst 200. The shape and size of the first connecting hole 220 are the same as those of the second connecting hole 230.

[0041] As shown in FIG. 1 and FIG. 3 , in one embodiment, there are two catalyst components 200, and both catalyst components 200 are mounted on the mounting component 300 and are respectively located on both sides of the first stopper 400 along the extension direction of the reaction channel 110. In this way, the mounting component 300 is limited on the first stopper 400 by using the corresponding limit cooperation of the two catalyst components 200 and the first stopper 400 along the extension direction of the reaction channel 110, so as to ensure that the mounting component 300 will not move out of the reaction channel 110, thereby improving the reliability of the packing structure 10.

[0042] As shown in FIG. 1 and FIG. 3 , further, the first stopper 400 is provided with a mounting hole, the mounting member 300 is provided as a double-headed screw 310, the double-headed screw 310 is passed through the mounting hole, and cooperates with the inner side wall of the mounting hole along the radial limit of the reaction channel 110, the two catalytic components 200 are respectively installed at both ends of the double-headed screw 310, and the packing structure 10 also includes a locking nut 510, and each of the two sides of each catalytic component 200 is provided with a locking nut 510, and each locking nut 510 is threadedly connected with the double-headed screw 310, so as to lock the two catalytic components 200 on the double-headed screw 310. In this way, the mounting member 300 and the two catalytic components 200 can be fixed as one, thereby improving the reliability of the packing structure 10.

[0043] Optionally, the threads at both ends of the double-headed screw 310 have opposite rotation directions. The two catalyst components 200 are respectively provided with a first internal thread and a second internal thread for threaded connection at both ends of the double-headed screw 310, and the thread rotation direction of the first internal thread and the thread rotation direction of the second internal thread are opposite. In this way, the rotation and tightening directions of the two catalyst components 200 are opposite, so that the connection strength between the double-headed screw 310 and the two catalyst components 200 is increased, and the reliability of the packing structure 10 is improved. Specifically in this embodiment, the surface of the double-headed screw 310 is first polished and smoothed, and then pickled and passivated.

[0044] As shown in Fig. 3, optionally, the first stopper 400 is interference fit with the reaction channel 110. In this way, the first stopper 400 can be stably and reliably fixed in the reaction channel 110 to limit the radial movement of the mounting member 300 in the reaction channel 110 along the reaction channel 110, thereby improving the reliability of the packing structure 10.

[0045] As shown in FIG1 , optionally, the axis of the mounting member 300 is located on the same straight line as the axis of the reaction channel 110. In this way, the catalyst member 200 on the mounting member 300 is also located on the same straight line as the axis of the reaction channel 110, thereby ensuring that the catalyst member 200 does not interfere with the reaction body 100 during the rotation process, thereby improving the reliability of the packing structure 10.

[0046] As shown in Figures 3 and 4, in one embodiment, the first limit member 400 includes a mounting ring, a connecting rod 410 and an arc-shaped fixing plate 420; the mounting ring (the inner hole of the mounting ring corresponds to the mounting hole) is sleeved on the outer wall of the mounting member 300 and rotatably cooperates with the outer wall of the mounting member 300, the number of the connecting rod 410 and the arc-shaped fixing plate 420 are at least one, one end of the connecting rod 410 is fixedly connected to the mounting ring, and the other end of the connecting rod 410 is fixedly connected to the arc-shaped solid block plate, and the arc-shaped fixing plate 420 is interference fit with the reaction channel 110.

[0047] The number of the connecting rods 410 and the arc-shaped fixing plates 420 can be flexibly adjusted according to the actual needs of use. Specifically in this embodiment, the number of the connecting rods 410 and the arc-shaped fixing plates 420 are three. The outer wall of the mounting ring is provided with three connecting holes, and the three connecting holes are arranged at intervals around the central axis of the mounting ring. One end of the three connecting rods 410 is plugged and matched with the three connecting holes in a one-to-one correspondence. The three arc-shaped fixing plates 420 are fixedly connected with the other ends of the three connecting rods 410 in a one-to-one correspondence.

[0048] As shown in Fig. 1, Fig. 3 and Fig. 5, one end of the reaction channel 110 is set as a liquid inlet end 111, and the packing structure 10 also includes an adsorbent 600, which is installed at the liquid inlet end 111 and is used to adsorb solid particles in the treated medium. In this way, the adsorbent 600 can adsorb small solid impurities in the treated medium, thereby improving the treatment effect and reliability of the packing structure 10.

[0049] The adsorbent 600 may be any structure in the prior art capable of adsorbing solid particles. Specifically in this embodiment, the adsorbent 600 may be a carbon rod.

[0050] As shown in Fig. 1 and Fig. 5, further, one end of the mounting member 300 extending to the liquid inlet end 111 is set as a connecting end 311, and the packing structure 10 further includes a locking member 700, which is used to lock and match the connecting end 311 with the adsorbent 600. In this way, the adsorbent 600 can be detachably mounted on the mounting member 300 through the locking member 700, which is convenient for subsequent maintenance and replacement of the adsorbent 600, thereby improving the practicality of the packing structure 10.

[0051] The locking member 700 may be configured as a clamp, an optical axis fixing ring or other locking structures.

[0052] As shown in FIG6 , optionally, the packing structure 10 further includes a second stopper 800, which is installed between the outer side wall of the connection end 311 and the inner side wall of the liquid inlet end 111, and is used to limit the radial movement of the connection end 311 along the reaction channel 110 in the liquid inlet end 111. In this way, the second stopper 800 can further increase the connection strength between the mounting member 300 and the reaction body 100, and improve the reliability of the packing structure 10.

[0053] As shown in FIG6 , optionally, the packing structure 10 further includes a third stopper 900, which is installed between the outer wall of the adsorbent 600 and the inner wall of the liquid inlet end 111, and is used to limit the radial movement of the adsorbent 600 along the reaction channel 110 in the liquid inlet end 111. In this way, the adsorbent 600 is also fixed at the liquid inlet end 111 by the third stopper 900, ensuring that the position of the adsorbent 600 in the liquid inlet end 111 remains stable, thereby improving the reliability of the packing structure 10.

[0054] Specifically in this embodiment, the structure of the second limiting member 800 and the structure of the third limiting member 900 are the same as or similar to the structure of the first limiting member 400, and will not be described in detail herein.

[0055] As shown in FIG. 6 , in one embodiment, a catalytic oxidation device is provided, comprising at least one filler structure 10 as in any of the above embodiments.

[0056] When the catalytic oxidation device in the above embodiment is used, the catalyst element 200 is correspondingly installed in the reaction channel 110 to assemble and form a packing structure 10. When the treated medium needs to be subjected to catalytic oxidation treatment, the treated medium is input from one end of the reaction channel 110, so that the treated medium is fully in contact with the catalyst element 200 during the flow in the reaction channel 110 and a catalytic oxidation reaction occurs, and then the organic matter in the treated medium is oxidized and decomposed into harmless substances such as water and carbon dioxide, thereby achieving the purpose of purification. Compared with the catalytic oxidation method in the prior art, the catalytic oxidation device in the present application has at least the following advantages: 1. The catalyst element 200 is set as a porous hollow structure, so that the contact area between the treated medium and the catalyst element 200 is increased during the flow of the treated medium in the reaction channel 110, ensuring that the treated medium can fully react with the catalyst element 200 and increase the reaction efficiency. 2. When the flow rate and pressure of the treated medium entering the reaction channel 110 are high, the catalytic element 200 can block and buffer the treated medium, so that the flow rate and pressure of the treated medium are reduced, ensuring that there is sufficient contact reaction time between the treated medium and the catalytic element 200, thereby improving the treatment effect and reliability of the catalytic oxidation equipment. 3. The mechanical components of the packing structure 10 are simple, and there are no dead corners inside the reaction channel 110, which will not cause secondary pollution, thereby improving the treatment effect and reliability of the catalytic oxidation equipment. 4. The packing structure 10 is a multi-stage structure. Different types of catalytic elements 200 can be selected according to the different treated media, and the number of packing structures 10 can be increased or decreased according to actual use requirements. It is easy to operate and occupies a small area. 5. When conducting a catalytic oxidation reaction, there is no need to add other agents, and no solid waste is generated, thereby reducing the initial design investment cost and later maintenance cost of the catalytic oxidation equipment.

[0057] The catalytic oxidation device can flexibly adjust the number of packing structures 10 according to actual use needs. For example, the catalytic oxidation device can choose to increase or decrease the packing structure 10 according to the concentration of the treated medium, the type of medium and other characteristics. Specifically in this embodiment, when there are at least two packing structures 10, the catalytic elements 200 in different packing structures 10 can be the same or different.

[0058] Specifically in this embodiment, the catalytic oxidation device includes two packing structures 10, and the two packing structures 10 are connected to each other. Along the flow direction of the treated medium, the first reaction channel 110 is set as a catalytic oxidation packing area, and the second reaction channel 110 is set as a secondary reaction area. The catalytic oxidation device also includes a detection sensor, which is used to detect the content of organic matter in the treated medium. The input end of the catalytic oxidation packing area and the output end of the secondary reaction area are both provided with detection sensors. In this way, after the treated medium enters the catalytic oxidation packing area for the first catalytic oxidation reaction, it enters the secondary reaction area for the second catalytic oxidation reaction, and is discharged after being detected by the detection sensors at the input end of the catalytic oxidation packing area and the output end of the secondary reaction area to meet the standards, thereby improving the reliability of the catalytic oxidation device.

[0059] As shown in FIG. 1 , in one embodiment, the reaction body 100 includes a cylinder 120 , two seals 140 and two chucks 130 . The two chucks 130 are respectively located at two ends of the cylinder 120 , and are correspondingly sealed and connected to the two ends of the cylinder 120 through the two seals 140 .

[0060] Among them, the end cap 140 can be set as an equal-diameter end cap or a different-diameter end cap. A chuck 130, a end cap 140, a cylinder 120, another end cap 140 and another chuck 130 can be connected in sequence to form a reaction channel 110. The cylinder 120 and the end cap 140, and the end cap 140 and the chuck 130 can be sealed and connected by clamping, screwing, plugging or other detachable methods. Specifically in this embodiment, both ends of the cylinder 120 and the ends of the end cap 140 are welded with connecting chucks. The cylinder 120 and the end cap 140, and the end cap 140 and the chuck 130 are sealed and connected through a single-pin two-petal clamp locking structure.

[0061] Specifically in this embodiment, the connection between the cylinder 120 and the end cap 140, and the connection between the end cap 140 and the chuck 130 are all smooth transitions. In this way, it is ensured that there is no dead corner inside the reaction channel 110, no secondary pollution will be caused, and the treatment effect and reliability of the catalytic oxidation device are improved.

[0062] Optionally, the catalytic oxidation device further comprises a seal, and when two adjacent packing structures 10 are butted, a seal is provided between two butted chucks 130 to seal and match the two corresponding chucks 130. In this way, the reliability of the catalytic oxidation device is improved.

[0063] The sealing member may be a sealing gasket, a sealing washer or other sealing structures. Specifically in this embodiment, the sealing member is configured as a sealing gasket, which is made of a high temperature resistant and corrosion resistant material.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0066] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0067] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0068] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0069] It should also be understood that when explaining the connection relationship or positional relationship of elements, although not explicitly described, the connection relationship and positional relationship are interpreted as including an error range, which should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" may mean within one or more standard deviations, which are not limited here.

[0070] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
