[0033] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application and how the technical solutions in the present application solve the above-mentioned technical problems will be clearly and completely described below with specific embodiments and in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0035] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0036] Fenton technology is a widely used and promising technology for treating difficult-to-degrade industrial wastewater. It uses ferrous ions to catalyze hydrogen peroxide to produce hydroxyl radicals in an acidic environment, effectively removing difficult-to-degrade organic pollutants. Fenton-like technology is based on Fenton technology and uses heterogeneous catalyst materials to replace ferrous ions to significantly reduce the amount of reagents added and the amount of iron sludge produced. There are two common forms of Fenton-like reactors: fluidized bed and fixed bed. Fenton-like fluidized bed reactors are widely used in wastewater treatment projects in printing and dyeing, papermaking, chemical industry and other industries due to their high mass transfer efficiency and simple operation.

[0037] In the related art, a Fenton-like fluidized bed reactor is one in which a heterogeneous catalyst material is loaded into a filler shell with a porous structure, and a high circulating water flow rate is injected into the filler shell to put the catalyst in a fluidized state, thereby fully mixing the catalyst and the wastewater to achieve a catalytic effect.

[0038] However, there is a contradiction between catalyst particle size, fluidization difficulty and loss rate, that is, small-particle catalysts are easy to fluidize and easy to lose, while large-particle catalysts are not easy to lose but difficult to fluidize. Therefore, in order to prevent small-particle catalysts from escaping from the packing shell and losing, the above reactors are mostly large-particle catalyst materials, which leads to a large specific gravity of the fluidized carrier and difficulty in fluidization; in addition, when the specific gravity of the fluidized carrier is large, it needs to be fluidized by a large amount of water and high flow rate reflux, resulting in high energy consumption of Fenton-like fluidized bed reactors.

[0039] Therefore, the present application provides a catalytic structure and a Fenton-like reactor, wherein the catalyst structure includes a carrier assembly and a plurality of catalyst bodies; a carrier is arranged, the carrier is used to be arranged in a Fenton-like reactor and is connected to the Fenton-like reactor; at least two slide rails are arranged inside the carrier, so that a plurality of catalyst bodies are arranged on each slide rail at intervals; after a fluid is introduced into the Fenton-like reactor, the carrier serves as a matrix of a fluidized bed of the Fenton-like reactor, the fluid flows through the matrix and drives the catalyst to move along the slide rail, so that the catalyst body can be kept fluidized in a limited space, thereby avoiding the loss of the catalyst body from the carrier; thus, a plurality of small-particle catalyst bodies can be arranged in the carrier to reduce the specific gravity of the fluidized carrier, thereby facilitating fluidization.

[0040] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the utility model in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0041] Figure 1 Structural schematic diagram of the catalytic structure provided in the embodiments of the present application Figure 1 ; Figure 2 Structural schematic diagram of the catalytic structure provided in the embodiments of the present application Figure 2 .

[0042] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a catalytic structure 100 for use in a Fenton-like reactor, including a carrier assembly 110 and a plurality of catalyst bodies 120 .

[0043] The carrier assembly 110 includes a carrier 111 and at least two slide rails 112 disposed inside the carrier 111 . The carrier 111 is used to be disposed in a Fenton-like reactor and is connected to the Fenton-like reactor. At least two catalyst bodies 120 are spaced apart and penetrated on the slide rails 112 .

[0044] The catalyst body 120 is configured to move along the slide rail 112 under the fluidization effect of a Fenton-like reactor.

[0045] Among them, the catalyst body 120 is a heterogeneous catalyst material. Exemplarily, the catalyst body 120 can be a supported multi-metal catalyst, such as a substrate of silicon oxide, aluminum oxide or activated carbon, and the supported metals are at least two of iron, manganese, copper, cobalt, nickel, cerium and metal oxides thereof, so that multiple metal active components are supported on a substrate, so that the catalyst body 120 has higher catalytic activity and selectivity based on the synergistic effect between different metals, thereby improving the efficiency of the catalytic reaction.

[0046] In a specific configuration, the carrier 111 is disposed in a Fenton-like reactor and is connected to the Fenton-like reactor so that fluid exchange can be achieved between the Fenton-like reactor and the interior of the carrier 111 .

[0047] Furthermore, the carrier 111 has a hollow structure, and at least two slide rails 112 are provided inside the carrier 111 , and a plurality of catalyst bodies 120 are provided on each slide rail 112 at intervals, so that the fluid entering the carrier 111 can produce a fluidization effect on the catalyst.

[0048] It can be understood that the fluid introduced into the Fenton-like reactor is wastewater that needs to be purified.

[0049] In actual application, after wastewater is introduced into the Fenton-like reactor, the carrier 111 serves as the matrix of the fluidized bed of the Fenton-like reactor. The wastewater flows through the matrix and drives the catalyst to move along the slide rail 112, so that the catalyst body 120 can remain fluidized in a limited space.

[0050] In this way, the catalyst body 120 moves irregularly along the slide rail 112, which can prevent the catalyst body 120 from being lost from the carrier 111; in this way, a plurality of small-particle catalyst bodies 120 can be arranged in the carrier 111 to reduce the specific gravity of the fluidized bed, thereby facilitating fluidization, thereby increasing the contact probability between hydroxyl radicals in the catalytic reaction and difficult-to-degrade organic pollutants in the wastewater.

[0051] It should be noted that the type, quantity and particle size of the catalyst body 120, the size of the carrier 111 and the number of slide rails 112 can be set according to the Fenton-like reactor configuration and the adaptability to the wastewater quality, and the embodiments of the present application do not limit this.

[0052] In some embodiments, the carrier 111 is a hollow structure surrounded by a mesh.

[0053] In this application, if Figure 1 As shown, the carrier 111 is surrounded by mesh parts, so that the carrier 111 has evenly distributed mesh holes, and the wastewater in the Fenton-like reactor enters the interior of the carrier 111 through the mesh holes to ensure sufficient water flow exchange.

[0054] Furthermore, the carrier 111 surrounded by the mesh has a hollow structure, so that multiple slide rails 112 can be fixed in the carrier 111, and the catalyst bodies 120 are arranged on the slide rails 112 at intervals; illustratively, the carrier 111 can be a spherical mesh structure or a columnar mesh structure. The embodiments of the present application are only given as examples, and can be specifically set according to the number of catalyst bodies 120 participating in the reaction and the size adaptability of the Fenton-like reactor. The embodiments of the present application do not limit this.

[0055] In actual application, wastewater enters the carrier 111 through the mesh holes, so that the catalyst body 120 is suspended in the wastewater and moves irregularly along the slide rail 112 to form a fluidized state, so that the catalyst body 120 is fully in contact with the wastewater, thereby improving the reaction rate and efficiency.

[0056] In this way, under the action of water flow, while the carrier 111 and the catalyst body 120 are fluidized, the small-particle catalyst body 120 can avoid leaking from the mesh holes of the carrier 111 and is not easy to be lost.

[0057] In some embodiments, the mesh is a plastic mesh.

[0058] In the present application, the mesh member may be a thermoplastic mesh, such as a high-density polyethylene mesh or a polypropylene mesh that is injection molded or extruded into a hollow structure.

[0059] In this way, it can be ensured that the density of the carrier 111 is less than the density of the wastewater introduced into the Fenton-like reactor. During the reaction stage, the fluidization of the carrier 111 and the catalyst body 120 can be achieved through a smaller aeration volume or reflux water volume, thereby reducing the energy consumption and operating costs of the Fenton-like reactor.

[0060] It should be noted that the mesh is a polyethylene mesh or a polypropylene mesh, which is only given as an example and can be adaptively set according to actual needs, as long as the density of the mesh is less than the fluid, and the mesh is stable in nature, does not chemically react with the fluid, is resistant to chemical corrosion, has good mechanical properties, and is easy to process.

[0061] In some embodiments, the carrier 111 has a first fixed point 1111 and a second fixed point 1112, which are relatively arranged on the inner wall of the carrier 111, and one end of the slide rail 112 is used to connect to the first fixed point 1111, and the other end is used to connect to the second fixed point 1112.

[0062] In this application, continue as Figure 1As shown, exemplarily, the carrier 111 is a hollow spherical structure, and the inner wall of the carrier 111 has a first fixed point 1111 and a second fixed point 1112 relative to each other, and the two ends of the slide rail 112 are respectively connected to the first fixed point 1111 and the second fixed point 1112, so that the slide rail 112 extends from the first fixed point 1111 to the second fixed point 1112, and the catalyst body 120 can move between the first fixed point 1111 and the second fixed point 1112 when being fluidized.

[0063] In the embodiment of the present application, exemplarily, the first fixed point 1111 and the second fixed point 1112 are respectively located in the diameter direction of the hollow ball structure, and the number of the slide rails 112 is nine, and the slide rails 112 are straight or arc-shaped, that is, one slide rail 112 is straight in the diameter direction, and the remaining eight slide rails 112 are arc-shaped and distributed on both sides of the straight slide rail 112.

[0064] In this way, the space inside the carrier 111 can be fully utilized to extend each slide rail 112 as long as possible, thereby facilitating the installation of more catalyst bodies 120 on one slide rail 112, thereby allowing the wastewater to be thoroughly catalyzed by a sufficient number of catalyst bodies 120 to improve the wastewater treatment effect.

[0065] In some embodiments, the carrier 111 is a hollow columnar structure, and the first fixed point 1111 and the second fixed point 1112 are respectively located between the top surface and the bottom surface; it can be understood that the number of the first fixed point 1111, the second fixed point 1112 and the slide rail 112 corresponds to each other, and each slide rail 112 is distributed in a straight line; in this way, the catalyst body 120 can be evenly distributed in the carrier 111, so that it is easy for the wastewater to fluidize the carrier 111 and the catalyst body 120.

[0066] In some embodiments, the slide rail 112 is adhesively fixed to both the first fixing point 1111 and the second fixing point 1112 .

[0067] In the present application, the slide rail 112 is fixed to the first fixed point 1111 and the second fixed point 1112 by bonding. For example, after one end of the slide rail 112 is bonded to the second fixed point 1112, the catalyst body 120 is sequentially inserted into the slide rail 112, and finally the other end of the slide rail 112 is bonded to the first fixed point 1111 by adhesive.

[0068] By bonding and fixing, not only is it easy to connect and assemble the catalyst body 120, the slide rail 112 and the carrier 111, but also the slide rail 112 and the carrier 111 have good integrity without loose accessories. While ensuring the connection strength, the overall weight of the catalytic structure 100 is not increased. The lightweight design allows a smaller aeration volume or reflux water volume to achieve the fluidization effect on the carrier 111 and the catalyst body 120.

[0069] It should be noted that when bonding, factors such as the selection of adhesive, surface treatment, bonding pressure and temperature need to be considered to ensure the bonding effect and quality, thereby avoiding the slide rail 112 from detaching from the carrier 111 during the fluidized reaction stage, causing small-particle catalyst bodies 120 to escape from the carrier 111 and cause the catalyst bodies 120 to be lost.

[0070] In some embodiments, the rails 112 are spaced evenly apart.

[0071] In this application, if Figure 1 and Figure 2 As shown, by arranging a plurality of slide rails 112 with equal spacing in the carrier 111 , after the catalyst body 120 is passed through each slide rail 112 , the overall weight distribution of the carrier 111 is uniform.

[0072] In the embodiment of the present application, each slide rail 112 is distributed on the same plane inside the carrier 111, and the plane includes the maximum dimension inside the hollow structure of the carrier. When the carrier 111 is a spherical structure, the plane passes through the center of the spherical structure.

[0073] In some embodiments, Figure 2 As shown, the slide rails 112 are distributed around the inner wall of the carrier 111 in a circumferential manner, and one of the slide rails 112 is arranged to pass through the center of the circle.

[0074] It should be noted that the spacing between the slide rails 112 can be set according to the number of slide rails 112 and the adaptability of the size of the carrier 111. The embodiments of the present application are only given for illustrative purposes and are not specifically limited to this.

[0075] In actual application, the overall weight distribution of the carrier 111 is uniform, so that the wastewater in the Fenton-like reactor can fluidize the carrier 111 and the catalyst body 120 in the carrier 111 at an appropriate flow rate, and the reaction process is also uniform, stable and controllable. At the same time, it also helps to evenly transfer the reaction heat to avoid local overheating or overcooling, improve the heat utilization efficiency, thereby further improving the reaction efficiency in the reactor, and also helping to reduce the energy consumption of the Fenton-like reactor.

[0076] In some embodiments, a plurality of limiting points 1121 are provided at intervals on the slide rail 112 , and the catalyst body 120 is located between two adjacent limiting points 1121 , so that the catalyst body 120 can move between the two limiting points 1121 .

[0077] In this application, if Figure 1 and Figure 2As shown, the slide rail 112 has a plurality of limit points 1121 arranged in sequence at intervals, and the catalyst body 120 is located between two adjacent limit points 1121. When the wastewater fluidizes the carrier 111 and the catalyst body 120, the catalyst body 120 moves irregularly between the two limit points 1121; illustratively, the catalyst body 120 moves along the slide rail 112 between the two limit points 1121, or rotates around the slide rail 112.

[0078] In this way, the catalyst bodies 120 are distributed more evenly in the matrix and are easy to fluidize, so as to avoid the accumulation of multiple catalyst bodies 120 on the same slide rail 112. The aggregation of particles leads to a high fluidization ratio and difficulty in fluidization.

[0079] In some embodiments, the slide rail 112 is a plastic member.

[0080] In the present application, the slide rail 112 is a plastic part. For example, the slide rail 112 can be made of the same material as the carrier 111. The carrier 111 and one end of the slide rail 112 can be connected together through injection molding. The other end of the slide rail 112 passes through the catalyst body 120 and then connected to the carrier 111.

[0081] In this way, not only is the connection process between the slide rail 112 and the carrier 111 simplified, but by setting the slide rail 112 as a plastic part, the slide rail 112 can be made lightweight, so that the common density of the carrier 111 and the slide rail 112 is close to or less than the fluid density in the Fenton-like reactor. During the reaction stage, the fluidization of the carrier 111 and the catalyst body 120 can be achieved through a smaller aeration volume or reflux water volume, thereby reducing the energy consumption and operating cost of the Fenton-like reactor.

[0082] It should be noted that the material of the slide rail 112 is given for illustrative purposes only and may also be other lightweight structural parts, as long as the density of the slide rail 112 is less than that of the fluid, has good mechanical properties, is easy to process, and does not chemically react with the fluid and the catalyst body 120 .

[0083] In some embodiments, a mounting hole is provided on the catalyst body 120 , and the slide rail 112 passes through the mounting hole to be connected with the catalyst body 120 .

[0084] In the present application, the catalyst body 120 is a supported multi-metal catalyst. For example, the substrate is silicon oxide, and the supported metals are iron, copper, cerium and oxides thereof.

[0085] In some embodiments, the substrate of the catalyst body 120 is activated carbon, and the supported metals are iron, manganese, cobalt and oxides thereof.

[0086] In the specific configuration, a mounting hole is processed on the substrate of the catalyst body 120 by sintering process, and the mounting hole is used to penetrate the slide rail 112. It can be understood that the diameter of the mounting hole matches the outer diameter of the slide rail 112, so that the two can be easily installed in series.

[0087] In some embodiments, the catalyst body 120 is a spherical structure, and the mounting hole is opened in the diameter direction of the spherical structure.

[0088] In some embodiments, the catalyst body 120 is a columnar structure, and the mounting hole is opened at the center of the columnar structure.

[0089] It should be noted that the structure of the catalyst body 120 in the embodiment of the present application is only given as an example, and the catalyst body 120 can also be other hollow structures, as long as it is ensured that the catalyst body 120 can be passed through the slide rail 112, and the catalyst body 120 reduces its own weight as much as possible on the basis of meeting the reaction requirements to facilitate fluidization.

[0090] On the basis of the above embodiments, this embodiment provides a Fenton-like reactor, comprising a reactor body and any one of the above catalytic structures 100 disposed in the reactor body.

[0091] The specific structure of the catalytic structure 100 has been described in detail in the above embodiments, and will not be described again here.

[0092] In the embodiment of the present application, the reactor body is a closed container, and the catalytic structure 100 is arranged inside the container. After the wastewater is introduced into the container, the carrier 111 serves as the matrix of the fluidized bed of the Fenton-like reactor. The wastewater flows through the matrix and drives the catalyst to move along the slide rail 112. By arranging a plurality of small-particle catalyst bodies 120 on the slide rail 112, the reactor can easily fluidize the catalytic structure 100, so that the catalyst body 120 is not easy to lose and remains fluidized in a limited space, thereby increasing the contact probability between the hydroxyl radicals in the catalytic reaction and the difficult-to-degrade organic pollutants in the wastewater, thereby improving the wastewater treatment effect.

[0093] In some embodiments, the reactor body further includes a stirring device. For example, the stirring device may be a stirrer or a stirring paddle, etc., for maintaining uniform mixing of the reaction materials in the reactor body and promoting the reaction.

[0094] In some embodiments, the reactor body also includes an acid-base adjustment system. Fenton-like reactions usually need to be carried out under acidic conditions to generate more hydroxyl radicals in the reaction and improve the reaction efficiency with difficult-to-degrade organic pollutants in the wastewater.
