Description

Technical Field

[0001] This utility model relates to the field of packing technology, and in particular to a high-strength ceramic corrugated packing for chemical separation. Background Technology

[0002] According to Chinese Patent No. CN209885818U, a lightweight ceramic packing ring includes an outer ring body with an inner ring body. Support ribs are provided on the outer side of the inner ring body. This invention employs a nested structure of the outer and inner ring bodies, connected and supported by the support ribs. This effectively improves the structural strength of both the inner and outer ring bodies, ensuring their stability. Simultaneously, the inner ring body divides the interior of the outer ring body into a circular outer cavity and a circular inner cavity. The inner and outer cavities work together to divert flow, reducing flow resistance and improving fluidity. The use of a first and second outer cavity tongue plate in a layered configuration effectively reduces the channel resistance of the outer cavity and improves the mixing efficiency of gas and liquid within it. Similarly, the use of a first and second inner cavity tongue plate in a layered configuration reduces the channel resistance of the inner cavity, resulting in a more stable structure.

[0003] The inner walls of the cylindrical ceramic packings described above and in the prior art are all smooth surfaces, and the flow path of the liquid within them is relatively direct. The liquid mainly flows through the inner wall of the packing, and the flow direction is relatively unidirectional, resulting in a small contact area between the liquid and the gas, which in turn leads to a relatively low mass transfer efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the relatively simple flow path of liquid in the packing in the prior art, and to propose a high-strength ceramic corrugated packing for chemical separation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength ceramic corrugated packing for chemical separation, comprising an outer ring body, an inner ring body inside the outer ring body, eight support columns surrounding the outer side of the inner ring body, support column corrugations on both sides of the eight support columns, eight square holes on the surface of the outer ring body, a first inner corrugation on the inner wall of both the outer and inner ring bodies, a second inner corrugation at the bottom of the first inner corrugation of both the outer and inner ring bodies, a first outer corrugation on the outer surface of the inner ring body, a second outer corrugation at the bottom of the first outer corrugation, and eight sets of circular holes surrounding the outer surface of the inner ring body.

[0006] Preferably, the eight square holes on the surface of the outer ring are evenly arranged at the top and bottom of the outer ring in groups of four, and each group of square holes is equally spaced around the surface of the outer ring, with the two groups of square holes arranged perpendicularly to each other.

[0007] Preferably, the first inner corrugations on the inner surface of the inner ring and the outer ring are both located at the top of the inner ring and the outer ring, and the second inner corrugations at the bottom of the first inner corrugations on the inner and outer rings are both located on the inner wall at the bottom of the inner ring and the outer ring.

[0008] Preferably, the first outer corrugation on the outer surface of the inner ring is located at the top of the outer surface of the inner ring, and the second outer corrugation at the bottom of the first outer corrugation is located at the bottom of the outer surface of the inner ring.

[0009] Preferably, the eight support columns are evenly arranged at the top and bottom of the inner ring body in groups of four, and each group of support columns is equally spaced around the outer surface of the inner ring body, with the two groups of support columns arranged perpendicularly to each other.

[0010] Preferably, one end of each of the eight support columns is located on the outer surface of the inner ring body, and the other end of each support column is located on the inner surface of the outer ring body, wherein the outer ring body, the inner ring body, and the support columns are integrally formed.

[0011] Preferably, the eight groups of circular holes are arranged in groups of eight, and the eight groups of circular holes are equally spaced around the surface of the inner ring.

[0012] Beneficial effects

[0013] In this invention, a first inner corrugation and a second inner corrugation are provided on the inner surface of the outer ring and the inner ring, and a first outer corrugation and a second outer corrugation are provided on the outer surface of the inner ring. Furthermore, support corrugations are provided on both sides of the eight support columns. This spiral corrugated structure enables the fluid to form complex flow paths within the packing. When the gas and liquid phases contact within the packing, the spiral corrugations increase the contact area and contact time between the two phases. The fluid continuously splits and merges between the corrugations, promoting turbulence formation and helping to break the mass transfer boundary layer, thereby improving mass transfer efficiency and overcoming the drawback of relatively simple flow paths for liquids within the packing.

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0024] Reference Figure 1-5 A high-strength ceramic corrugated packing for chemical separation includes an outer ring body 1, an inner ring body 2 inside the outer ring body 1, eight support columns 4 surrounding the outer side of the inner ring body 2, and support column corrugations 9 on both sides of the eight support columns 4. The surface of the outer ring body 1 has eight square holes 3. The inner walls of both the outer ring body 1 and the inner ring body 2 have first inner corrugations 5, and the bottom of the first inner corrugations 5 of both the outer ring body 1 and the inner ring body 2 has second inner corrugations 6. The outer surface of the inner ring body 2 has first outer corrugations 7, and the bottom of the first outer corrugations 7 has second outer corrugations 8. The outer surface of the inner ring body 2 is surrounded by eight sets of circular holes 10. The eight square holes 3 on the surface of the outer ring body 1 are evenly arranged in groups of four at the top and bottom of the outer ring body 1, with each group of square holes 3 evenly spaced around the surface of the outer ring body 1. Two groups of square holes 3 are arranged perpendicularly. The first inner corrugations 5 on the inner surfaces of both the inner ring body 2 and the outer ring body 1 are... The inner ring 2 and outer ring 1 are set at the top. The second inner corrugation 6 at the bottom of the first inner corrugation 5 on the surface of the inner ring 2 and outer ring 1 are both set on the bottom inner wall of the inner ring 2 and outer ring 1. The first outer corrugation 7 on the outer surface of the inner ring 2 is set at the top of the outer surface of the inner ring 2, and the second outer corrugation 8 at the bottom of the first outer corrugation 7 is set at the bottom of the outer surface of the inner ring 2. Eight support columns 4 are evenly set at the top and bottom of the inner ring 2 in groups of four. Each group of support columns 4 is equally spaced around the outer surface of the inner ring 2. The two groups of support columns 4 are perpendicularly intersecting. One end of the eight support columns 4 is set on the outer surface of the inner ring 2, and the other end of the support columns 4 is set on the inner surface of the outer ring 1. The outer ring 1, inner ring 2 and support columns 4 are integrally formed. Eight groups of circular holes 10 are set at groups of eight. The eight groups of circular holes 10 are equally spaced around the surface of the inner ring 2.

[0025] The ceramic corrugated packing consists of an outer ring 1, an inner ring 2, and support columns 4. The outer ring 1 and inner ring 2 are nested together, and eight support columns 4 connect the inner and outer rings, providing support and reinforcement. The outer ring 1, inner ring 2, and support columns 4 are integrally formed, ensuring the stability of the overall structure. The outer ring 1 has eight square holes 3 on its surface, arranged in groups of four, located at the top and bottom, and evenly spaced around the surface of the outer ring 1. The two groups of square holes 3 intersect perpendicularly. These square holes 3 facilitate fluid entry and exit from the packing and guide fluid distribution within the packing. The outer surface of the inner ring 2 is surrounded by eight groups of circular holes 10, with each group of eight circular holes 10 evenly spaced. The presence of the circular holes 10 allows for more uniform fluid flow and distribution around the inner ring 2. The inner walls of the outer ring 1 and inner ring 2 are provided with a first inner corrugation 5 (located at the top) and a second inner corrugation 6 (located at the bottom inner wall), with the first inner corrugation 5 and the second inner corrugation 6 having opposite thread directions. This reversed thread design guides the fluid to form a complex flow path inside the ring. The outer surface of the inner ring 2 is provided with a first outer corrugation 7 (located at the top) and a second outer corrugation 8 (located at the bottom). The threads of the first outer corrugation 7 and the second outer corrugation 8 are also in opposite directions to guide the fluid surrounding the inner ring 2. The surfaces on both sides of the eight support columns 4 are provided with support corrugations 9, which can assist the mixing and mass transfer of the fluid to a certain extent. Specific Implementation Example 2:

[0027] Reference Figure 1-5The effect is that the presence of the first inner corrugation 5, the second inner corrugation 6, the first outer corrugation 7, and the second outer corrugation 8 increases the contact area of ​​the fluid. When the fluid flows through these corrugations, it flows along the path formed by the corrugations, resulting in more contact opportunities between the gas and liquid phases. Because the threads of the first inner corrugation are opposite to those of the second inner corrugation, the first outer corrugation, and the second outer corrugation, the direction of the fluid constantly changes as it flows on the inner and outer surfaces of the inner and outer rings, promoting fluid mixing and turbulence formation, breaking the mass transfer boundary layer, and facilitating the diffusion and transfer of solute between phases, thereby improving mass transfer efficiency. The square holes 3 and the circular holes 10 can guide the fluid to enter and exit the packing uniformly. After entering the packing through these holes, the fluid will be uniformly distributed within the packing under the guidance of the corrugations. The corrugated spiral pattern prevents unidirectional flow and localized aggregation of the fluid, ensuring full contact of the fluid throughout the packing and guaranteeing uniform fluid distribution. This improves the efficiency of the chemical separation process. Eight support columns 4 connect the outer ring 1 and the inner ring 2, and the support columns 4 themselves possess sufficient strength to withstand the pressure and fluid impact that may occur during chemical separation. The integrated molding design makes the entire packing structure more stable, less prone to deformation or damage, and ensures the reliability of the packing during long-term use, making it particularly suitable for high-intensity chemical separation environments. Due to the complex path of the corrugations and the guidance of the reverse spiral pattern, the fluid flow path within the packing becomes more tortuous. The fluid needs to spend more time passing through the packing, thus extending its residence time. In chemical separation, appropriately extending the residence time facilitates sufficient exchange of solutes between phases, improving separation efficiency. The corrugated pillars 9 on both sides of the support columns 4 create localized mixing and disturbance of the fluid flowing near the support columns 4. This helps to further break down the fluid boundary layer, allowing the solutes in the fluid to better contact other phases, thus playing an auxiliary role in mass transfer and enhancing the overall mass transfer performance of the packing.

[0028] In summary:

[0029] 1. A spiral corrugated structure is employed, featuring first inner corrugations 5 and second inner corrugations 6 on the inner surfaces of the outer ring 1 and inner ring 3, and first outer corrugations 7 and second outer corrugations 8 on the outer surface of the inner ring 2. Furthermore, support corrugations 9 are provided on both sides of the eight support columns 4. This spiral corrugated structure enables the fluid to form complex flow paths within the packing. When the gas and liquid phases contact within the packing, the spiral corrugations increase the contact area and contact time between the two phases. The continuous splitting and merging of the fluid between the corrugations promotes turbulence formation, helps break the mass transfer boundary layer, thereby improving mass transfer efficiency and overcoming the drawback of relatively simple flow paths for liquids within the packing.
