Description

Technical Field

[0001] This application relates to the field of reactor packing technology, specifically to a reactor packing assembly and a reactor. Background Technology

[0002] Bubble cap towers are common reactor packing components in the chemical engineering field. Their main internal structure is a bubble cap tray with multiple bubble cap structures containing riser pipes. These riser pipes allow chemical gases to escape through the gaps around the bubble caps, ensuring the chemical gases fill the entire tower and facilitate sufficient contact with the reaction liquid being treated or diluted, thus improving the reaction efficiency and quality of the reactor packing assembly. However, the bubble cap structures on these trays are complex, with small gaps, making them prone to clogging. Clogging necessitates shutdown and access through the nearest manhole for maintenance, complicating the overall tower structure. In chemical production, most bubble cap towers have been replaced by packed towers. Existing packing materials, including corrugated packing, have weak overall stability, are prone to deformation or damage due to uneven stress, and are inconvenient to install and have a short service life. Therefore, this invention provides a reactor packing assembly to address the shortcomings of existing packing materials. Summary of the Invention

[0003] This utility model provides a packing assembly and a reactor to solve the problems of poor stability and inconvenient installation of existing corrugated packing structures.

[0004] In a first aspect, this utility model discloses a packing assembly for a reactor, comprising: a hexagonal base, a regular packing block, and a water distribution plate connected to the top of the packing block. The water distribution plate is connected to the packing block via a connector, and the packing block is nested to the hexagonal base. The cross-section of the packing block is a regularly arranged array of equilateral triangles, and its overall structure is a hexagonal prism or cylinder. The water distribution plate is uniformly provided with a plurality of downwardly protruding frustum-shaped water guide holes.

[0005] In this design, the packing assembly consists of regular packing blocks, a water distribution plate at the top of the packing blocks, and a hexagonal base at the bottom of the packing blocks. In this overall structure, the packing blocks, with their regular equilateral triangular cross-sections, are not only structurally stable and resistant to deformation, but also ensure that each air-permeable space is of equal size, resulting in uniform air permeability and improved stability of the packing structure. Furthermore, this packing assembly can be spliced ​​with other packing assemblies on the same horizontal plane. During splicing, the hexagonal base is pushed to align with the outer edge of the hexagonal bases of surrounding packing assemblies, enhancing the ease of installation of the packing structure.

[0006] In addition, the water distribution plate in the packing assembly ensures that the falling liquid is evenly dispersed within the packing blocks, promoting full contact between the liquid and the gas rising along the packing, further enhancing the reactor's reaction efficiency. The packing blocks can have a hexagonal prism structure or a cylindrical structure. However, with a cylindrical structure, there will be some open space after adjacent packing components are joined. The specific choice can be made based on the relevant technical parameters of the actual reactor.

[0007] Optionally, the water distribution plate is a circular or regular hexagonal structure.

[0008] In this design, the shape of the water distribution plate corresponds to or complements the cross-sectional shape of the packing block below. Specifically, if the packing block is a cylindrical structure, the water distribution plate can be a circle with the same diameter as the packing block; if it is a regular hexagon, the size of the regular hexagon is equal to the size of the hexagonal base, and the inscribed circle of the regular hexagonal water distribution plate should be equal to the diameter of the cylindrical packing block.

[0009] Optionally, it also includes a grid disposed on the bottom surface of the hexagonal base. The grid includes an outer ring, vertical ribs and horizontal ribs. The vertical ribs and the horizontal ribs are stainless steel round tubes. The vertical ribs and the horizontal ribs are installed in layers inside the outer ring. The outer wall of the horizontal rib is flush with the outer surface of the outer ring.

[0010] In this design, the grid is a structure that separates the upper and lower packing assemblies. During installation, the packing assemblies move on the surface of the grid. The grid can also be configured to connect to the inside of the reactor, i.e., a limiting groove or limiting bar is provided on the inner wall of the reactor to fix the grid, so that the grid is locked in the limiting groove or rests on the limiting bar.

[0011] Optionally, the filler block is ceramic.

[0012] In this design, ceramic material packing blocks are designed to improve the wear resistance and corrosion resistance of the packing assembly, thereby effectively extending the service life of the packing assembly.

[0013] Optionally, the outer wall of the packing block is provided with the circular hole.

[0014] In this design, permeable circular holes are provided on the outer wall of the packing blocks in some packing assemblies, allowing the gas rising along the packing blocks to overflow from these holes and enter the space between the packing assembly and the inner wall of the reactor, so that the gas is evenly distributed throughout the entire reactor, further improving the reactor's reaction efficiency.

[0015] Secondly, this utility model discloses a reactor comprising a skirt, a tower body, a liquid distributor composed of multiple sets of spray pipes arranged side by side, a demister, and a packing assembly used in the tower body as described above for the reactor. The bottom end of the tower body is connected to the skirt, and the skirt is fixed to the ground. The demister comprises a base plate and a mat connected to the base plate, and the base plate is placed on the spray pipe assembly.

[0016] This invention discloses a reactor comprising the aforementioned packing assembly and other components thereof, including a liquid distributor and a demister, for performing a gas-liquid exchange reaction. Based on the design concept of the aforementioned packing assembly, this reactor offers the advantages of strong packing structure stability and ease of installation, thereby improving the reaction efficiency in the gas-liquid exchange process.

[0017] Optionally, the tower body includes a plurality of manholes, the manholes being positioned opposite the grille.

[0018] In this design, a manhole is provided at the position opposite to the grid of the packing assembly inside the reactor. When the packing assembly inside the reactor needs to be removed for maintenance or replacement, it can be taken out through the manhole, which effectively improves the convenience of reactor maintenance and installation.

[0019] Optionally, the air inlet of the reactor is located at the bottom of the tower body, and the air outlet of the reactor is used to communicate with the air inlet of the adjacent reactor, or to connect the air outlet of a single reactor to the air inlet through a conduit.

[0020] In this design, two of the aforementioned reactors are connected in series to improve the reactor's processing quality, such as enhancing the absorption of harmful impurities in the gas. Alternatively, in a single reactor, the gas outlet at the top of the reactor is reconnected to the gas inlet at the bottom of the reactor via a conduit, allowing for further processing of the treated gas and achieving multiple thorough reactions, thus effectively improving the reactor's processing quality.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] This utility model provides a packing assembly and a reactor, wherein the packing assembly improves the stability of the packing structure in the reactor and the ease of installation of the packing structure. The reactor has the effect of strong packing structure stability and easy installation, thereby improving the reaction effect in the gas-liquid exchange process of the reactor.

[0032] The technical solutions in the embodiments of the application will now be clearly and completely described with reference to the accompanying drawings. Furthermore, the phrases "in one embodiment" or "in one embodiment" appearing throughout this specification do not necessarily refer to the same embodiment. Moreover, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0033] The packing structures in existing reactors used for gas-liquid exchange are mostly corrugated. These packings need to be installed layer by layer or rolled into a bundle from the center outwards. This type of packing is not only inconvenient to install, but its structure is also prone to deformation after installation, meaning its overall stability is weak. Sometimes it is easily damaged due to uneven local stress. In view of this, this utility model provides a packing assembly and reactor for a reactor to solve the shortcomings of existing packings.

[0034] Please refer to the appendix for details. Figures 1 to 7 As shown, this utility model provides a packing assembly for a reactor and a reactor.

[0035] In a first aspect, this utility model discloses a packing assembly for a reactor, comprising: a hexagonal base 1, a regular packing block 2, and a water distribution plate 3 connected to the top of the packing block 2. The water distribution plate 3 is connected to the packing block 2 by a connector, and the packing block 2 is nested to the hexagonal base 1. The cross-section of the packing block 2 is a regular array of equilateral triangles, and its overall structure is a hexagonal prism or cylinder. The water distribution plate 3 is uniformly provided with a plurality of downwardly protruding frustum-shaped water guide holes 31.

[0036] In this design, such as Figure 1 As shown, the packing assembly consists of regular packing blocks 2, a water distribution plate 3 at the upper end of the packing blocks 2, and a hexagonal base 1 at the lower end of the packing blocks 2. Figure 4 As shown, the cross-section of the packing block 2 is a regular equilateral triangle. This structure is not only stable and not easily deformed, but also ensures that each air-permeable space is of equal size, resulting in uniform air permeability and effectively improving the stability of the packing structure. The water distribution plate 3 at the upper end of the packing block 2 can be connected and fixed to it via a connector. This connector can be a support structure made of plate or columnar material, and the packing assembly can be manufactured using an integral molding process.

[0037] In addition, such as Figure 2 As shown, during installation, this packing assembly can be spliced ​​with other packing assemblies on the same horizontal plane. During splicing, the operator pushes the hexagonal base 1 of a single packing assembly closer to the surrounding packing assemblies. Because its base is a regular hexagonal structure, three packing assemblies can be spliced ​​together to form a complete plane; that is, six other packing assemblies can be spliced ​​around a single packing assembly. This installation method is not only convenient but also allows for self-calibration of the installation position, effectively improving the ease of installation of the packing structure.

[0038] In addition, the water distribution plate 3 in the packing assembly provided by this utility model makes the falling liquid evenly dispersed in the packing block 2, promotes full contact between the liquid in the reactor and the gas rising along the packing, and further improves the reaction effect of the reactor.

[0039] Among them, such as Figure 1 As shown, the structure of packing block 2 can be a hexagonal prism structure or a cylindrical structure. Of course, when it is a cylindrical structure, there is a certain amount of empty space after adjacent packing components are spliced ​​together. The specific choice can be made according to the relevant technical parameters of the actual reactor.

[0040] In some embodiments, the aforementioned water distribution plate 3 is a circular or regular hexagonal structure.

[0041] In this design, the shape of the water distribution plate 3 corresponds to or complements the cross-sectional shape of the packing block 2 below. Specifically, if the packing block 2 is a cylindrical structure, the water distribution plate 3 can be a circle with the same diameter as the packing block 2. If the packing block 2 is a regular hexagon, where the size of the regular hexagon is the same as the size of the hexagonal base 1, the inscribed circle of the regular hexagonal water distribution plate 3 should be equal to the diameter of the cylindrical packing block 2. The multiple downward-protruding frustum-shaped water guide holes 31 on the water distribution plate 3 are used to guide the liquid, ensuring that the incoming liquid is evenly distributed on the packing block 2.

[0042] In some embodiments, the present invention further includes a grid 4 disposed on the bottom surface of the hexagonal base 1. The grid 4 includes an outer ring 41, vertical ribs 43 and horizontal ribs 42. The vertical ribs 43 and horizontal ribs 42 are stainless steel round tubes. The vertical ribs 43 and horizontal ribs 42 are installed in layers inside the outer ring 41. The outer wall of the horizontal ribs 42 is flush with the outer surface of the outer ring 41.

[0043] like Figure 3 As shown, mutually perpendicular horizontal ribs 42 and vertical ribs 43 are installed inside the outer ring 41. Both horizontal ribs 42 and vertical ribs 43 are designed as circular tubes to reduce resistance to rising gas. The horizontal ribs 42 or vertical ribs 43 need to be flush with the outer surface of the outer ring 41 to jointly support the hexagonal base 1 of the packing block 2. In this design, the grid 4 is used to separate the upper and lower packing assemblies. During installation, the packing assemblies move on the surface of the grid 4. Alternatively, the grid 4 can be connected to the inside of the reactor, i.e., a limiting groove or limiting rod is provided on the inner wall of the reactor to fix the grid 4, securing it in the limiting groove or placing it on the limiting rod.

[0044] In some embodiments, the packing block 2 in the aforementioned packing assembly is ceramic.

[0045] In this design, the ceramic material packing block 2 is designed to improve the wear resistance and corrosion resistance of the packing assembly, thereby effectively extending the service life of the packing assembly.

[0046] In some embodiments, the outer wall of the aforementioned packing block 2 is provided with a circular hole.

[0047] In this design, permeable circular holes are provided on the outer wall of the packing block 2 in some packing assemblies. This allows gas rising along the packing block 2 to overflow through these holes and enter the space between the packing assembly and the inner wall of the reactor, ensuring that the gas is evenly distributed throughout the reactor and further improving the reactor's reaction efficiency. Of course, this part of the packing assembly is installed at the position closest to the inner wall of the reactor.

[0048] Secondly, this utility model discloses a reactor comprising a skirt base 5, a tower body 6, a liquid distributor 7 composed of multiple sets of spray pipes arranged side by side, a demister 8, and a packing assembly used in any of the aforementioned reactors located within the tower body 6. The bottom end of the tower body 6 is connected to the skirt base 5, and the skirt base 5 is fixed to the ground. The demister 8 includes a base plate 81 and a mating mattress 82 connected to the base plate 81, and the base plate 81 is placed on the spray pipe assembly.

[0049] like Figure 5 As shown, this solution also discloses a reactor comprising the aforementioned packing assembly and other devices constituting the reactor, including a liquid distributor 7 and a demister 8, for gas-liquid exchange reactions. The reactor includes multiple layers of the aforementioned stacked packing assembly. A liquid distributor 7 is installed on the upper layer of the reactor to uniformly spray the liquid absorbing the gas onto the packing assembly. Additionally, the demister 8 at the top prevents the generation of bubbles or foam within the reactor, which could affect the reactor's internal pressure or reaction efficiency. Based on the design concept of the aforementioned packing assembly, this reactor offers the advantages of strong packing structure stability and ease of installation, thereby improving the reaction efficiency in the gas-liquid exchange process.

[0050] It should be noted that in this embodiment, the liquid distributor 7 is configured with multiple sets of spray pipes arranged side by side to improve the uniformity of liquid distribution. Additionally, as... Figure 6 As shown, the demister 8 is configured to include a base plate 81 and a mattress 82, wherein the mattress 82 is used to break up foam or absorb foam components.

[0051] In some embodiments, the aforementioned tower body 6 includes a plurality of manholes, the manholes being positioned opposite to the grille 4.

[0052] In this design, a manhole is provided at the position opposite to the grid 4 of the packing assembly inside the reactor. When the packing assembly inside the reactor needs to be taken out for maintenance or replacement, it can be taken out through the manhole, which effectively improves the convenience of reactor maintenance and installation.

[0053] In other embodiments, multiple reactors can be used in series, or the outlet and inlet of a single reactor can be reconnected to allow the reactor to repeatedly process the gas. Figure 7 As shown (the black arrows in the figure indicate the flow direction of the gas to be treated), the gas inlet of the reactor is located at the bottom of the tower body 6, and the gas outlet of the reactor is used to connect with the gas inlet of the adjacent reactor, or to connect the gas outlet of a single reactor with the gas inlet through a conduit.

[0054] In this design, two of the aforementioned reactors are connected in series to improve the reactor's processing quality, such as enhancing the absorption of harmful impurities in the gas. Alternatively, in a single reactor, the gas outlet at the top of the reactor is reconnected to the gas inlet at the bottom of the reactor via a conduit, allowing for further processing of the treated gas and achieving multiple thorough reactions, thus effectively improving the reactor's processing quality.

[0055] Finally, this utility model provides a packing assembly and a reactor. The packing assembly includes a hexagonal base 1, regular packing blocks 2, and a water distribution plate 3 connected to the top of the packing blocks 2. The packing blocks 2 are nested and connected to the hexagonal base 1. The cross-section of the packing blocks 2 is a regularly arranged array of equilateral triangles, and its overall structure is a hexagonal prism or cylinder. The water distribution plate 3 is uniformly provided with multiple downward-protruding frustum-shaped water guide holes 31. The reactor includes a skirt 5, a tower body 6, a liquid distributor 7 composed of multiple sets of side-by-side spray pipes, a demister 8, and a packing assembly installed inside the tower body 6. This utility model improves the stability of the packing structure in the reactor and the ease of installation of the packing structure, and also improves the reaction effect of the reactor in gas-liquid exchange processes.
