Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel structure, specifically to a high-efficiency chlorine dioxide generator. Background Technology
[0002] Chlorine dioxide is an internationally recognized safe and non-toxic green disinfectant. Due to its strong selective oxidation ability and broad-spectrum and efficient bactericidal ability, it has been used in many fields such as pulp and fiber bleaching, drinking water disinfection, food processing, preservation, wastewater treatment, medical disinfection and sterilization, bleaching, water injection for oil recovery, oil well unclogging, and control of biological pollution.
[0003] Currently, existing technologies generally use reaction vessels or multi-stage reactors in series to produce chlorine dioxide. Because the catalyst used is at least one of ruthenium, palladium, platinum, ruthenium oxide, palladium oxide, and platinum oxide, and this catalyst is a solid catalyst, it will sink to the bottom of the reaction vessel due to its high density, thus avoiding contact with the reaction liquid. This phenomenon reduces catalytic efficiency. To improve the utilization rate of raw materials, operation at higher temperatures and higher acidity is required. This not only results in high raw material consumption, low chlorine dioxide purity, and severe equipment corrosion, but also produces a large amount of residual liquid, leading to high treatment costs, which seriously restricts the widespread application of chlorine dioxide.
[0004] In view of the above, this application is hereby submitted. Utility Model Content
[0005] The purpose of this invention is to provide a high-efficiency chlorine dioxide generator. This generator sets a catalyst in the reactor body and sets a gap between the catalyst and the bottom wall of the reactor body, so that the raw materials for the chlorine dioxide generation reaction can flow above the catalyst and in the gap, thereby solving the problem of insufficient contact between the solid catalyst and the reaction raw materials and low catalytic efficiency in the prior art.

[0013] Optionally, the catalyst has a plate-like structure and is located between the upper cover and the lower cover, with a gap between the catalyst and the upper cover and a gap between the catalyst and the lower cover;
[0014] The catalyst has several third through holes on its plate-like structure.
[0015] Optionally, it also includes a stirring element located inside the reactor body, including a rotating rod and stirring blades, with the stirring blades mounted on the rotating rod, and the rotating rod being driven by a driving mechanism to rotate the stirring blades.
[0016] Optionally, the upper cover is provided with a first mounting hole, the lower cover is provided with a second mounting hole, and the catalyst plate structure is provided with a third mounting hole. The rotating rod passes through the first mounting hole, the second mounting hole, and the third mounting hole simultaneously, and the rotating rod can rotate within the first mounting hole, the second mounting hole, and the third mounting hole.
[0017] Optionally, a limiting block is provided at the bottom of the rotating rod. The limiting block is located below the lower cover, and there is a gap between the limiting block and the bottom of the reactor body. The diameter of the limiting block is larger than the diameter of the second mounting hole.
[0018] Optionally, the limiting block is helically connected to the rotating rod, a top cover is movably provided at the upper end of the reactor body, and a motor is provided on the top rod to drive the rotating rod.
[0019] Optionally, the cylinder, the top cover, and the bottom cover are all made of titanium metal, and the catalyst includes at least one of ruthenium metal, palladium metal, platinum metal, ruthenium oxide, palladium oxide, and platinum oxide.
[0020] Optionally, the reactor body includes an upper part and a lower part, which are connected to each other. The upper part is located above the lower part, and the cross-section of the lower part gradually decreases from top to bottom. The catalyst is covered on the upper part of the lower part.
[0021] Compared with the prior art, the embodiments of this utility model have the following advantages and beneficial effects:
[0022] 1. The high-efficiency chlorine dioxide generator provided in this embodiment allows the raw material liquid to contact the catalyst in the reactor during the chlorine dioxide generation reaction, resulting in a chemical reaction that produces chlorine dioxide. By movably engaging the catalyst within the reactor body with a certain gap between it and the bottom wall of the reactor body, the reactants can flow freely above the catalyst and within the gap, increasing the contact area and contact time between the reactants and the catalyst, thus significantly improving catalytic efficiency. This structure can achieve efficient chlorine dioxide generation at lower temperatures and acidities, reducing raw material consumption, minimizing side reactions, and contributing to higher purity of the generated chlorine dioxide. The movably engaging catalyst within the reactor facilitates installation and replacement, improving the operability and maintenance convenience of the equipment.
[0023] 2. This embodiment of the invention, by configuring the catalyst element as a structure including a cylinder, an upper cover, and a lower cover, allows the catalyst to be flexibly confined inside the cylinder, ensuring that both the upper and lower ends of the catalyst are in full contact with the reaction liquid. Simultaneously, through holes are provided in the upper and lower covers to ensure the flow of the reaction liquid between the upper and lower ends of the catalyst element, ensuring that the chemical reaction in the reactor body proceeds fully and uniformly. The encapsulation structure of the cylinder, upper cover, and lower cover ensures that there is always a gap between the catalyst and the bottom of the reactor body, improving catalytic efficiency and raw material conversion rate.
[0024] 3. This embodiment of the invention, by incorporating a stirring element with a rotating rod and stirring blades, allows the rotating rod to drive the stirring blades to rotate via an external motor, thereby stirring the reaction liquid within the reactor body and improving the completeness and uniformity of the reaction. Importantly, this embodiment of the invention, by providing first, second, and third mounting holes on the upper cover, lower cover, and catalyst plate structure respectively, allows the rotating rod to rotate within these mounting holes, ensuring that the placement of the catalyst element does not interfere with the smooth stirring action of the stirring element.
[0025] 4. In this embodiment of the invention, the lower cross-section of the reactor body is designed to gradually decrease from top to bottom, allowing the catalyst to be moved and stably engaged with the upper part of the lower section of the reactor body. This facilitates the flexible disassembly, installation, and replacement of the catalyst. By designing a rotating rod that passes through the entire catalyst and a limiting block at the lower end of the rotating rod, which is located at the lower end of the lower cover and cannot pass through the second mounting hole, this structure not only ensures the smooth rotation of the rotating rod within multiple mounting holes but also allows the catalyst to be easily disassembled or installed in the reactor body simply by pulling or pushing the rotating rod during disassembly or installation, further improving the generator's flexibility.
[0026] In general, the high-efficiency chlorine dioxide generator provided by the embodiments of this utility model improves catalytic efficiency and saves sulfuric acid consumption by setting a catalyst element in the reactor body and setting a gap between the catalyst element and the bottom wall of the reactor body.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0037] In the description of this utility model, it should be noted that the terms "first", "second", "third", etc. are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.
[0038] Example
[0039] like Figure 1 As shown, this utility model embodiment provides a high-efficiency chlorine dioxide generator, comprising:
[0040] The reactor body 1 is used to contain the chlorine dioxide generation reaction, providing a closed space for the reaction to ensure that the reaction can proceed under controlled conditions. It should be noted that the shape of the reactor body 1 is not limited here; existing shapes can be used. The reactor body 1 can be designed as a single container, or it can be divided into two or more chambers by partitions for staged reactions. Similarly, the reactor body 1 can also be equipped with air inlets, temperature measuring ports, explosion-proof ports, chlorine dioxide extraction ports, feed inlets, and residual liquid discharge ports, etc., as needed. These structures can all be implemented using existing technologies and are not limited here.
[0041] The key feature of this embodiment is that the provided reactor also includes a catalyst 2. The catalyst 2 has a plate-like structure and is movably mounted inside the reactor body 1. There is a gap between the catalyst 2 and the bottom wall of the reactor body 1. The catalyst 2 is configured to provide a catalyst for the generation reaction of chlorine dioxide. The raw materials for the generation reaction of chlorine dioxide can flow above the catalyst 2 and in the gap.
[0042] Specifically, the catalyst is crucial for the chlorine dioxide generation reaction, accelerating the reaction rate and improving efficiency. It can be at least one of ruthenium, palladium, platinum, ruthenium oxide, palladium oxide, and platinum oxide, all of which are existing solid catalysts for chlorine dioxide generation. In this embodiment, the catalyst element 2 is movably mounted within the reactor body 1, with a certain gap between it and the bottom wall of the reactor body 1. This allows the reactants to flow freely above the catalyst element 2 and within the gap, increasing the contact area and contact time between the reactants and the catalyst, improving catalytic efficiency, and reducing reaction time. This structure enables efficient chlorine dioxide generation at lower temperatures and acidities, reducing raw material consumption. The lower reaction temperature and acidity reduce corrosion of the reactor, extending the equipment's lifespan. It also reduces side reactions, helping to improve the purity of the generated chlorine dioxide and reduce the amount of residual liquid produced by the chemical reaction, thus lowering residual liquid treatment costs. The movable mounting of the catalyst element 2 within the reactor facilitates installation and replacement, improving the equipment's operability and maintenance convenience.
[0043] As a preferred embodiment of this utility model, exemplarily, such as Figure 2 and Figure 3 As shown, the catalyst element 2 includes a cylindrical component 3, an upper cover 4, and a lower cover 5. The upper cover 4 covers the top of the cylindrical component 3, and the lower cover 5 covers the bottom of the cylindrical component 3. The upper cover 4 has several first through holes 6, and the lower cover 5 has several second through holes 7. The raw materials for the chlorine dioxide generation reaction can flow above the first through holes 6 and below the second through holes 7. The catalyst is placed inside the cylindrical component 3. In use, the reaction raw materials (such as sodium chlorate and acidic solution) are added through the feed port at the top of the reactor body 1. The raw materials enter the interior of the catalyst element 2 through the first through hole 6 of the upper cover 4. Inside the catalyst element 2, the raw materials come into contact with the catalyst and undergo a chemical reaction to generate chlorine dioxide. The generated chlorine dioxide and unreacted raw materials flow out of the catalyst element 2 through the second through holes 7 of the lower cover 5. Because there is a gap between the catalyst element 2 and the bottom wall of the reactor, the reaction raw materials can flow freely above the catalyst element 2 and in the gap, further improving the catalytic efficiency. Preferably, the connection between the cylinder 3 and the upper cover 4 and the lower cover 5 can be a spiral connection, a snap-fit connection, an adhesive connection, etc. There are no restrictions here as long as sufficient connection stability can be achieved. Of course, in order to add the catalyst to the cylinder 3 smoothly and conveniently, the connection between the cylinder 3 and the upper cover 4 and the lower cover 5 can be set as a snap-fit connection.
[0044] To improve the flowability at the upper and lower ends of the catalyst element 2, at least two first through holes 6 and at least two second through holes 7 can be provided, with each first through hole 6 and each second through hole 7 aligned vertically. This structure allows the reactants to enter the catalyst element 2 uniformly and flow out smoothly in the vertical direction, improving the flow efficiency of the reaction liquid and enhancing the uniformity and thoroughness of the catalytic reaction. Alternatively, in other embodiments, only one first through hole 6 and one second through hole 7 can be provided, and the flowability of the reaction liquid at the upper and lower ends of the catalyst element 2 can be improved by enlarging the size of the first through hole 6 and the second through hole 7. Therefore, the number, size, and arrangement of the first through holes 6 and the second through holes 7 are not limited in this embodiment of the invention, as long as the flowability of the reaction liquid at the upper and lower ends of the catalyst element 2 is ensured, thereby achieving the goal of improving the efficiency of the catalytic reaction.
[0045] In a preferred embodiment of this invention, the catalyst has a plate-like structure and is located between the upper cover 4 and the lower cover 5. There are gaps between the catalyst and the upper cover 4, and also gaps between the catalyst and the lower cover 5. Several third through holes 8 are provided on the plate-like structure of the catalyst. The third through holes 8 increase the specific surface area of the catalyst, providing more active sites, thereby improving catalytic performance. Since there are gaps between the plate-like structure of the catalyst and both the upper cover 4 and the lower cover 5, it not only ensures that the catalyst is in full contact with the reaction liquid within the cylinder 3, but also avoids affecting the flow efficiency of the reaction liquid at the upper and lower ends of the catalyst element 2 due to the arrangement of the catalyst. The arrangement of the third through holes 8 is similar to that of the first through holes 6 and the second through holes 7; the specific number, size, and positional layout are not limited.
[0046] Furthermore, this embodiment of the invention also includes a stirring element 9, which is located inside the reactor body 1 and includes a rotating rod 10 and a stirring blade 11. The stirring blade 11 is disposed on the rotating rod 10, and the rotating rod 10 is configured to drive the stirring blade 11 to rotate by a driving mechanism. The driving mechanism here can be any existing mechanical equipment or driving method, and is not limited here.
[0047] To ensure that the catalyst 2 in this embodiment does not affect the normal operation of the stirrer 9, preferably, the upper cover 4 is provided with a first mounting hole 12, the lower cover 5 is provided with a second mounting hole 13, and the plate-like structure of the catalyst is provided with a third mounting hole 14. The rotating rod 10 passes through the first mounting hole 12, the second mounting hole 13, and the third mounting hole 14 simultaneously, and the rotating rod 10 can rotate within the first mounting hole 12, the second mounting hole 13, and the third mounting hole 14. The arrangement of the stirrer 9 ensures the uniform distribution of the reaction raw materials in the reactor, further improving the reaction efficiency. Simultaneously, by providing the first mounting hole 12, the second mounting hole 13, and the third mounting hole 14 on the upper cover 4, the lower cover 5, and the plate-like structure of the catalyst respectively, the rotating rod 10 is allowed to rotate within these mounting holes, ensuring that the arrangement of the catalyst 2 does not affect the smooth stirring of the stirrer 9.
[0048] As a preferred embodiment of this utility model, such as Figure 4 As shown, a limiting block 15 is provided at the bottom of the rotating rod 10. The limiting block 15 is located below the lower cover 5, and there is a gap between the limiting block 15 and the bottom of the reactor body 1. The diameter of the limiting block 15 is larger than the diameter of the second mounting hole 13. In this embodiment of the present invention, the limiting block 15 is located at the lower end of the lower cover 5 and cannot pass through the second mounting hole 13. This structure not only ensures the smooth rotation of the rotating rod 10 in multiple mounting holes, but also allows the catalyst 2 to be easily disassembled or installed in the reactor body 1 simply by pulling or pushing the rotating rod 10 during disassembly or installation, further improving the flexibility of the generator.
[0049] More preferably, the limiting block 15 is spirally connected to the rotating rod 10, and a top cover 16 is movably disposed on the upper end of the reactor body 1. A motor 17 is disposed on the top rod, and the motor 17 is used to drive the rotating rod 10. By spirally connecting the limiting block 15 and the rotating rod 10, not only is the detachable structure of the limiting block 15 and the rotating rod 10 guaranteed, but also the stability of the connection is guaranteed. Of course, in other embodiments, the limiting block 15 and the rotating rod 10 can also be connected by integral setting, welding, bonding, etc., which is not limited here, as long as sufficient connection stability can be achieved. At the same time, by movably disposing of the top cover 16 on the upper end of the reactor body 1, the reactor body 1 can be fed by opening the top cover 16. The movable setting of the top cover 16 can further improve the flexibility of the reactor body 1, making it convenient to maintain and clean the inside of the reactor body 1. In order to improve the sealing of the reaction, a sealing ring can be provided at the upper opening of the top cover 16 and the reactor body 1.
[0050] The reactor body 1 includes an upper part 18 and a lower part 19, which are connected and positioned above each other. The upper part 18 is located above the lower part 19, and the cross-section of the lower part 19 gradually decreases from top to bottom. The catalyst element 2 is placed on top of the lower part 19. Specifically, the lower part 19 of the reactor body 1 is a conical structure or a downwardly convex arc-shaped structure. For ease of understanding, a conical structure is used as an example. This structure not only ensures the stability of the catalyst element 2 installed at the upper end of the lower part 19, but also has a flow guiding function. A discharge port 20 is provided at the bottom of the conical structure, which can improve the discharge efficiency of the liquid after the reaction. Preferably, an exhaust valve 21 can be provided at the upper end of the reactor body 1 to regulate the pressure inside the reactor body 1 and prevent the pressure in the reaction environment from being too high or too low.
[0051] It should be noted that the cylindrical component 3, the upper cover 4, and the lower cover 5 in this embodiment of the present invention can be made of titanium metal. Titanium metal has stable chemical properties and does not react chemically with the raw material liquid that generates chlorine dioxide, so it can be reused repeatedly. Of course, in other embodiments, the catalyst 2 can also have other structures, such as sheets or meshes made of one or more of ruthenium, palladium, and platinum. Ruthenium, palladium, and platinum can also be plated onto the titanium mesh, or ruthenium, palladium, and platinum compounds can be coated onto the titanium mesh and formed into metal oxides through sintering.
[0052] Through testing, the high-purity chlorine dioxide generator provided in this embodiment of the invention, when using sodium chlorate, hydrogen peroxide, and sulfuric acid as raw materials, under negative pressure conditions and with the reaction temperature controlled at 50-70 degrees Celsius, can increase the utilization rate of raw materials to 95%, save more than 45% of sulfuric acid consumption, and achieve a chlorine dioxide purity of 98%. Furthermore, the residual liquid (or mother liquor) produced during chlorine dioxide preparation is reduced by 47%, significantly lowering the cost of residual liquid treatment, and demonstrating broad application prospects. It has significant economic and social benefits.
[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model. It should be noted that the structures or components illustrated in the accompanying drawings are not necessarily drawn to scale, and descriptions of well-known components, processing techniques, and processes are omitted to avoid unnecessarily limiting the utility model.
