Description

Technical Field

[0001] This application relates to ceramic corrugations, and more particularly to a composite honeycomb ceramic corrugated filler. Background Technology

[0002] In the chemical and petrochemical industries, drying towers, washing towers, and distillation separation towers are core equipment for material separation and purification. The performance of their internal packing directly determines the separation efficiency, operational stability, and production cost. Currently, commonly used industrial tower packings are mainly divided into two categories: random packings and structured packings. Random packings, such as stepped rings, Pall rings, and Raschig rings, have the characteristics of simple structure and strong adaptability, but they generally have the limitations of low separation efficiency and high flow resistance. Structured packings are made of metals, plastics, and ceramics. Among them, ceramic corrugated structured packings have become one of the most widely used new structured packings in distillation separation towers in recent years due to their comprehensive advantages of good separation effect, resistance to acid and alkali corrosion, and low cost. They are a key core component for ensuring the separation of high-purity materials in the chemical and petrochemical fields.

[0003] However, existing ceramic corrugated structured packings still face significant bottlenecks in improving separation performance in practical applications. Traditional ceramic corrugated structured packings are formed by stacking several corrugated ceramic plates, with the corrugated channels of the upper and lower layers intersecting vertically. When the liquid flows between the packing layers, the abrupt change in channel direction leads to a significant increase in flow resistance and a decrease in flow velocity. It is difficult for the liquid to form a uniform turbulent flow within the packing, resulting in fewer contact times for the liquid droplets. Ultimately, this leads to uneven distribution of the liquid across the entire packing layer, directly restricting further improvement in distillation separation performance.

[0004] To address the bottleneck in separation performance of existing structured ceramic corrugated packings, this application proposes a combined honeycomb ceramic corrugated packing to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this application is to provide a combined honeycomb ceramic corrugated packing material, which has the advantages of good distillation effect and solves the problem that existing liquids are difficult to form uniform cross-flow turbulence inside the packing material and have a small number of droplet dispersion contacts.

[0006] The combined honeycomb ceramic corrugated packing provided in this application adopts the following technical solution: it includes several layers of stacked honeycomb corrugated monomers, the honeycomb corrugated monomers are sheet-like structures, the surface of the honeycomb corrugated monomers is pressed with continuous arc-shaped corrugations, the arc-shaped corrugations form a 45° angle with the length direction of the honeycomb corrugated monomers near the middle position, the top surface of the crest of the arc-shaped corrugations is provided with strip-shaped protrusions extending along the corrugation length, the top surface of the strip-shaped protrusions is provided with positioning holes, and the bottom of the adjacent layers of honeycomb corrugated monomers is fixedly connected with positioning pins, the positioning pins are adapted to the positioning holes; By adopting the above technical solution, the continuous arc-shaped corrugations pressed on the surface of the sheet-like honeycomb corrugated monomers, with a 45° angle to the length direction of the middle of the honeycomb corrugated monomers, allow the liquid to form a smooth flow path within the packing layer. This avoids the abrupt change in flow direction caused by traditional vertical staggered channels, effectively reducing flow resistance. The strip-shaped protrusions on the top surface of the corrugations provide an installation reference for the positioning holes. In conjunction with the positioning pins at the bottom of the adjacent honeycomb corrugated monomers and the positioning holes, precise positioning and stable connection between layers are achieved, preventing misalignment during stacking. The overall structure works synergistically to ensure the flatness of the packing layer, promote uniform liquid distribution between layers, create conditions for sufficient gas-liquid contact, and significantly improve the distillation separation effect.

[0007] Preferably, the angle of the arc-shaped corrugations gradually changes from the edge of the honeycomb corrugated unit to the center, and the arc-shaped corrugations near the edge are less than 45°.

[0008] By adopting the above technical solution, the arc-shaped corrugations gradually change from the edge to the center of the honeycomb corrugated cell, and the arc-shaped corrugations near the edge are less than 45°, making the liquid flow path in the edge area smoother and reducing the impact and retention of liquid at the edge. At the same time, the mass transfer efficiency of the central area is maintained at a 45° angle, making the liquid more evenly distributed on the entire cell surface, avoiding local liquid accumulation or flow gaps, and further optimizing the comprehensiveness of gas-liquid contact.

[0009] Preferably, the crests and troughs of the arc-shaped ripples are provided with protrusions, and the protrusions on adjacent sides are staggered.

[0010] By adopting the above technical solution, the protrusions set on the crest side and trough bottom of the arc-shaped ripples, combined with the staggered distribution of adjacent side protrusions, can form multi-point obstruction during liquid flow, increase the number of droplet dispersion contacts, and the staggered distribution design avoids the formation of continuous obstruction surfaces by the protrusions, enhances the turbulence effect, and effectively improves the gas-liquid mass transfer efficiency.

[0011] Preferably, the surface of the honeycomb corrugated monomer has honeycomb holes that penetrate the upper and lower surfaces, with the honeycomb holes in the upper layer being larger than those in the lower layer.

[0012] By adopting the above technical solution, the honeycomb pores that run through the upper and lower surfaces of the honeycomb corrugated monomer are designed with a larger pore diameter in the upper layer than in the lower layer. The larger pore diameter in the upper layer can quickly guide the liquid to diffuse laterally and avoid concentrated flow of the liquid in the upper layer, while the smaller pore diameter in the lower layer refines the liquid flow path and prolongs the residence time of the liquid in the lower layer. The pore diameters of the upper and lower layers work together to ensure the uniformity of liquid distribution and improve the adequacy of mass transfer.

[0013] Preferably, the diameter of the protrusion is 0.5-1mm, the height of the protrusion is 0.3mm, and the interval between the plurality of protrusions is 1-3mm.

[0014] By adopting the above technical solution, and by limiting the diameter, height and spacing of the protrusions, the protrusions can regulate the intensity of liquid turbulence, so that the flow will not be obstructed due to excessive size, nor will they fail to form effective vortices due to insufficient size.

[0015] Preferably, the strip-shaped protrusion is integrally formed with the honeycomb corrugated monomer, and the top of the strip-shaped protrusion is provided with a colloid.

[0016] By adopting the above technical solution, the strip-shaped boss and the honeycomb corrugated unit are integrally molded, avoiding structural gaps caused by later splicing, improving the connection strength between the boss and the honeycomb corrugated unit, preventing detachment or damage during use, and the adhesive set on the top of the strip-shaped boss can fully fill the tiny gaps between the upper and lower layer connection surfaces, further increasing the interlayer bonding area, strengthening the stability of the interlayer connection, and reducing the risk of delamination.

[0017] Preferably, the honeycomb corrugated monomer is a high-purity ceramic material, the length of the honeycomb corrugated monomer is 250mm, the troughs and peaks of the arc-shaped corrugations in adjacent layers cooperate with each other, and the colloid on the top of the strip-shaped protrusion is in contact with the trough of the arc-shaped corrugations.

[0018] By adopting the above technical solution, the honeycomb corrugated monomer uses high-purity ceramic materials, which have excellent high temperature resistance and acid and alkali corrosion resistance, making it suitable for harsh media environments in the chemical and petrochemical fields, extending the service life of the filler. The troughs and crests of the adjacent layers of arc-shaped corrugations cooperate with each other, so that the upper and lower layers of corrugations form a continuous flow channel, avoiding the occurrence of flow dead corners. The colloid on the top of the strip-shaped protrusions contacts the troughs of the arc-shaped corrugations, increasing the contact area between the colloid and the lower layer monomer, further improving the firmness of interlayer bonding.

[0019] In summary, this application includes at least one of the following beneficial technical effects: This composite honeycomb ceramic corrugated packing features continuous arc-shaped corrugations pressed onto the surface of sheet-like honeycomb corrugated monomers, forming a 45° angle with the length of the central part of the honeycomb corrugated monomers. This design allows the liquid to form a smooth flow path within the packing layer, avoiding abrupt changes in flow direction caused by traditional vertical staggered channels, effectively reducing flow resistance. The strip-shaped protrusions on the top surface of the corrugations provide an installation reference for the positioning holes. Combined with the positioning pins at the bottom of the adjacent honeycomb corrugated monomers, the positioning holes are matched to achieve precise positioning and stable connection between layers, preventing misalignment during stacking. The overall structure works synergistically to ensure the flatness of the packing layer, promote uniform liquid distribution between layers, create conditions for sufficient gas-liquid contact, and significantly improve the distillation separation effect.

[0022] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0023] Example 1: A combined honeycomb ceramic corrugated packing, referring to... Figure 1 , Figure 2 and Figure 5 The system comprises several stacked honeycomb corrugated units 1, each with a sheet-like structure. Continuous arc-shaped corrugations 2 are pressed onto the surface of each unit. The arc-shaped corrugations 2 form a 45° angle with the length direction of the honeycomb corrugated unit 1 near its center. A strip-shaped protrusion 7 extending along the corrugation length is provided on the crest of each arc-shaped corrugation 2. A positioning hole 6 is provided on the top surface of the strip-shaped protrusion 7. Positioning pins 5 are fixedly connected to the bottom of adjacent layers of honeycomb corrugated units 1, and these pins 5 are adapted to the positioning holes 6. The continuous arc-shaped corrugations 2 pressed onto the surface of the sheet-like honeycomb corrugated unit 1 interact with the corrugated units 1... The design with a 45° angle along the length of the section allows the liquid to form a smooth flow path within the packing layer, avoiding abrupt changes in flow direction caused by traditional vertical staggered channels, effectively reducing flow resistance. The strip-shaped protrusions 7 on the top surface of the crest provide an installation reference for the positioning holes 6. They are matched with the positioning pins 5 at the bottom of the adjacent honeycomb corrugated unit 1 and the positioning holes 6, achieving precise positioning and stable connection between layers, preventing misalignment during stacking. The overall structure works synergistically to ensure the flatness of the packing layer, promote uniform distribution of liquid between layers, create conditions for full gas-liquid contact, and significantly improve the distillation separation effect.

[0024] Example 2: A combined honeycomb ceramic corrugated packing material, Figure 1 , Figure 3 and Figure 4The angle of the arc-shaped corrugations 2 gradually changes from the edge to the center of the honeycomb corrugated cell 1. Near the edge, the angle of the arc-shaped corrugations 2 is less than 45°. This makes the liquid flow path in the edge area smoother, reducing liquid impact and retention at the edge. Simultaneously, the central area maintains a 45° angle for mass transfer efficiency, allowing for more uniform liquid distribution across the entire cell surface, avoiding localized liquid accumulation or flow gaps, and further optimizing the overall gas-liquid contact. The sides of the crests and bottoms of the troughs of the arc-shaped corrugations 2 are provided with protrusions 4, which are staggered between adjacent protrusions 4. The staggered distribution can form multiple obstructions during liquid flow, increasing the number of droplet dispersion contacts. The staggered distribution design avoids the formation of continuous obstruction surfaces by the protrusions 4, enhancing the turbulence effect and effectively improving the gas-liquid mass transfer efficiency. The surface of the honeycomb corrugated monomer 1 has honeycomb holes 3 that penetrate the upper and lower surfaces. The upper honeycomb holes 3 are larger than the lower honeycomb holes 3. The honeycomb holes 3 that penetrate the upper and lower surfaces of the honeycomb corrugated monomer 1 adopt the design of the upper layer hole diameter being larger than the lower layer. The larger upper layer hole diameter can quickly guide the liquid to diffuse laterally and avoid the liquid from concentrating in the upper layer. The smaller lower layer hole diameter refines the liquid flow path and prolongs the liquid residence time in the lower layer. The coordinated cooperation of the upper and lower layer hole diameters ensures the uniformity of liquid distribution and improves the sufficiency of mass transfer.

[0025] Example 3: A combined honeycomb ceramic corrugated packing material. Figure 1 , Figure 2 and Figure 3The diameter of the protrusion 4 is 0.5-1mm, the height of the protrusion 4 is 0.3mm, and the spacing between multiple protrusions 4 is 1-3mm. By limiting the diameter, height, and spacing range of the protrusions 4, the protrusions 4 can regulate the intensity of liquid turbulence. The protrusions 4 will not obstruct flow due to excessive size, nor will they fail to form effective vortices due to insufficient size. The strip-shaped protrusion 7 is integrally molded with the honeycomb corrugated monomer 1. An adhesive is provided on the top of the strip-shaped protrusion 7. This integral molding of the strip-shaped protrusion 7 and the honeycomb corrugated monomer 1 avoids structural gaps caused by later splicing, improves the connection strength between the protrusion and the honeycomb corrugated monomer 1, and prevents detachment or damage during use. The adhesive on the top of the strip-shaped protrusion 7 can fully fill the tiny gaps between the upper and lower layer connecting surfaces, further increasing the interlayer bonding area. To enhance the stability of interlayer bonding and reduce the risk of debonding, the honeycomb corrugated monomer 1 is made of high-purity ceramic material with a length of 250mm. This high-purity ceramic material provides excellent resistance to high temperatures and acid / alkali corrosion, making it suitable for harsh media environments in the chemical and petrochemical industries and extending the service life of the filler. The troughs and peaks of adjacent layers of arc-shaped corrugations 2 work together, and the colloid on the top of the strip-shaped protrusions 7 contacts the troughs of the arc-shaped corrugations 2. This interaction creates a continuous flow channel between the upper and lower corrugations, preventing dead zones. The contact between the colloid on the top of the strip-shaped protrusions 7 and the troughs of the arc-shaped corrugations 2 increases the contact area between the colloid and the lower layer monomer, further enhancing the strength of the interlayer bond.

[0026] The implementation principle of this application embodiment is as follows: In use, according to the internal specifications of drying towers, washing towers, or distillation separation towers in the chemical and petrochemical fields, several pieces of sheet-like honeycomb corrugated monomers 1 are stacked in layers. During the stacking process, the positioning pins 5 at the bottom of adjacent layers of honeycomb corrugated monomers 1 are precisely inserted into the positioning holes 6 on the top surface of the lower layer of strip-shaped protrusions 7. At the same time, the colloid on the top of the strip-shaped protrusions 7 is in full contact with the trough of the upper layer of arc-shaped corrugations 2. The precise alignment between layers is achieved by the adaptation of the positioning pins 5 and the positioning holes 6. Then, the gaps between the connecting surfaces are filled with colloid to form a stable and firm overall packing structure, ensuring that the packing layer is flat and without misalignment. After the packing is installed, the liquid flows from the upper tray of the separation tower into the surface of the top layer of honeycomb corrugated monomers 1, and begins to flow under the guidance of the continuous arc-shaped corrugations 2. Because the arc-shaped corrugations 2 form a 45° angle with the length direction of the middle part of the monomer, and The flow gradient from edge to center creates a smooth and uniform flow path for the liquid on the monomer surface, avoiding the surge in flow resistance caused by traditional vertical staggered channels and reducing impact retention in the edge area. During the flow, some liquid diffuses laterally through the honeycomb holes 3 that penetrate the upper and lower surfaces of the monomer. The larger honeycomb holes 3 in the upper layer quickly guide the liquid dispersion, while the smaller honeycomb holes 3 in the lower layer refine the flow path and prolong the liquid residence time. At the same time, the staggered distribution of protrusions 4 on the sides of the crests and bottoms of the troughs of the arc-shaped corrugations 2 forms multiple points of obstruction for the liquid, generating local eddies, increasing the number of droplet dispersion contacts, and enhancing the gas-liquid mass transfer effect. The troughs and crests of the adjacent layers of arc-shaped corrugations 2 cooperate with each other to form a continuous flow channel without dead angles, allowing the liquid to be evenly distributed throughout the entire packing layer and fully contact and collide with the rising airflow to achieve efficient distillation separation.
