Description

Technical Field

[0001] This utility model relates to the technical field of packed tower internals, and in particular to a multifunctional environmentally friendly packed tower internal. Background Technology

[0002] Packed towers are commonly used gas-liquid mass transfer devices with wide applications in chemical production. They utilize packing material within the tower as the contact component between the gas and liquid phases, offering advantages such as high production capacity, high separation efficiency, low pressure drop, low liquid holdup, and high operational flexibility. The tower body is a vertical cylinder with a packing support plate at the bottom. The packing material is placed on the support plate in a random or orderly manner. A packing pressure plate is installed above the packing to prevent it from being blown away by the rising gas flow. The internal components of the packed tower include the packing material, liquid distributor, support device, and packing clamping device.

[0003] To this end, Chinese patent application number CN221619466U discloses a multifunctional environmentally friendly packed tower internal component, relating to the technical field of packed tower internal components. It includes: an installation cylinder with a rubber pad on its top side, two support frames inside the installation cylinder, and wire mesh corrugated packing at the bottom. This utility model features an installation groove on the top side of the installation cylinder. By fixing the rubber pad onto the surface of the installation groove, the device can fill the gap between the installation cylinder and the tower body by squeezing the rubber pad when installed inside the tower, preventing fluid from flowing down through the gap and affecting the filtration effect. The support frames and wire mesh corrugated packing, together with the support inclined plate, can improve the filtration effect and production quality. In terms of materials, the chemical ceramic material used for the installation cylinder and support inclined plate, and the aluminum alloy material used for the support frames and wire mesh corrugated packing, are more durable, extending the service life of the device and saving costs.

[0004] While the internal components of modern packed towers can generally meet people's needs, some problems still exist, as detailed below:

[0005] 1. The problem of difficulty in improving gas-liquid mass transfer efficiency in packed tower internals: Packed towers require liquid to flow downwards along the packing surface from the top of the tower and gas to flow upwards from the bottom of the tower, with countercurrent mass transfer between the liquid and gas. It is necessary to accelerate the reaction rate by improving the gas-liquid mass transfer efficiency, thereby improving production efficiency.

[0006] 2. The problem of difficulty in improving the separation effect of packed tower internals: The whole packing is often punched during the production process. However, after production, there will be burrs of various sizes in the holes, which will affect the uneven distribution of gas and liquid. Furthermore, after punching, the strength is poor due to long-term use, which will lead to damage and affect the service life. Utility Model Content

[0007] The purpose of this invention is to provide a multifunctional and environmentally friendly packed tower internal to solve the shortcomings of existing packed tower internals in improving gas-liquid mass transfer efficiency and separation effect.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multifunctional environmentally friendly packed tower internal component, including a first mounting cylinder;

[0009] An expansion ring is installed on the outer side of the top of the first mounting cylinder, and a placement groove is provided on the inner side wall of the first mounting cylinder.

[0010] The bottom of the first mounting cylinder is engaged with a support structure, the inside of the first mounting cylinder is equipped with a separation structure, and the bottom of the first mounting cylinder is engaged with a second mounting cylinder.

[0011] The second mounting cylinder has a mass transfer structure installed inside. The mass transfer structure includes a first metal mesh, a second metal mesh, a third metal mesh, and diamond-shaped holes. The first metal mesh is installed inside the second mounting cylinder, and a second metal mesh is provided at one end of the first metal mesh.

[0012] In use, the first and second mounting cylinders are first interlocked according to the usage requirements. During the interlocking process, the expansion ring expands and seals the connection inside the packed tower. The liquid flows downward from the top of the tower along the surface of various packing materials, while the gas flows upward from the bottom of the tower, undergoing countercurrent mass transfer with the liquid. As the gas and liquid pass through the interior of the first mounting cylinder, they pass over the surface of the spiral packing, increasing the gas-liquid contact area and improving the separation effect. When the gas and liquid enter the second mounting cylinder, mass transfer between the two phases occurs. The support structure is installed in the placement groove opened inside the first and second mounting cylinders to prevent the various packing materials from shaking during use.

[0013] Furthermore, the support structure includes a rubber ring, a first metal wire mesh, and a second metal wire mesh. The rubber ring is installed inside the placement groove, and the first metal wire mesh is installed inside the rubber ring. The second metal wire mesh is installed at the bottom end of the first metal wire mesh, which can form a filter layer and provide support for other fillers.

[0014] Furthermore, a third metal mesh is provided on one side of the second metal mesh. The third metal mesh is wavy, which can increase the gas-liquid contact area.

[0015] Furthermore, the first, second, and third metal mesh sheets are all provided with diamond-shaped holes inside. These diamond-shaped holes are arranged at equal intervals inside the first, second, and third metal mesh sheets, which reduces pressure drop and wall flow through the gaps.

[0016] Furthermore, the separation structure includes spiral packing, perforations, and adhesion patterns. The spiral packing is installed inside the first mounting cylinder, and the outer wall of the spiral packing is provided with adhesion patterns, which can increase the gas-liquid contact area and the adhesion ability of the liquid.

[0017] Furthermore, the spiral packing has perforations inside, which are distributed in a ring shape to facilitate the flow of gas and liquid, reduce resistance damage caused by uneven gas and liquid distribution, and further improve the gas and liquid distribution.

[0018] Furthermore, the bottom end of the first mounting cylinder is provided with a slot, and the bottom end of the second mounting cylinder is provided with a locking block. The first mounting cylinder and the second mounting cylinder are interlocked, which facilitates free combination and installation.

[0019] This utility model provides a multifunctional environmentally friendly packed tower internal component, which has the following advantages: The multifunctional environmentally friendly packed tower internal component adopts a modular design, and can be flexibly installed and freely adjusted through the snap-fit ​​of the first and second mounting cylinders. The support structure provides support for the mass transfer structure and the separation structure and they are connected together to form a filter layer. The mass transfer structure can significantly improve the gas-liquid mass transfer rate while reducing costs, and can effectively improve the gas-liquid mass transfer efficiency. The separation structure increases the gas-liquid contact area, ensures smooth gas-liquid flow and sufficient contact time, and reduces the resistance damage caused by gas-liquid unevenness, further improving the gas-liquid distribution.

[0020] By installing multiple sets of first, second, and third metal meshes inside the second mounting cylinder, the cost can be reduced by more than 30% compared to metal wire mesh corrugated packing under the same separation conditions. The opening of the diamond-shaped holes greatly improves the gas-liquid mass transfer rate, which can effectively improve the gas-liquid mass transfer efficiency. The gap between the first, second, and third metal meshes can further reduce the pressure drop and reduce the generation of wall flow, thereby achieving the goal of improving the gas-liquid mass transfer efficiency of the packed tower internals.

[0021] By installing spiral packing inside the first mounting cylinder, the spiral packing is made of stainless steel and designed in a regular spiral structure to increase the gas-liquid contact area. Adhesion texture is set on the outer wall of the spiral packing to enhance the adhesion of the liquid. Multiple perforations are made in a ring shape inside the spiral packing to ensure smooth gas-liquid flow and sufficient contact time, thereby achieving the purpose of improving the separation effect of the packed tower internals.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 One embodiment of this utility model is a multifunctional environmentally friendly packed tower internal component, including a first mounting cylinder 1.

[0030] An expansion ring 2 is installed on the outer side of the top of the first mounting cylinder 1, and a placement groove 3 is provided on the inner side wall of the first mounting cylinder 1.

[0031] The bottom of the first mounting cylinder 1 is fitted with a support structure 4. The support structure 4 includes a rubber ring 401, a first metal wire mesh 402 and a second metal wire mesh 403. The rubber ring 401 is installed inside the placement groove 3. The first metal wire mesh 402 is installed inside the rubber ring 401. The second metal wire mesh 403 is installed at the bottom of the first metal wire mesh 402.

[0032] See attached document Figure 1 and attached Figure 4As shown, the first metal wire mesh 402 and the second metal wire mesh 403 are connected together to form a filter layer and provide support for other fillers. Rubber rings 401 are installed on the outside of the first metal wire mesh 402 and the second metal wire mesh 403 to wrap the edges. This not only increases the service life of the spiral filler 601 and improves the filtration effect of chemical liquids, but also improves the flatness of the surfaces of the first metal wire mesh 402 and the second metal wire mesh 403, ensuring that the first metal wire mesh 402 and the second metal wire mesh 403 are safe to use and easy to maintain. The rubber rings 401 are snapped into the inside of the placement groove 3, thereby preventing the various fillers from shaking during use and ensuring the normal and stable operation of the various fillers to a certain extent.

[0033] The first mounting cylinder 1 has a separation structure 6 installed inside. The separation structure 6 includes a spiral packing 601, a punch 602, and an adhesion pattern 603. The spiral packing 601 is installed inside the first mounting cylinder 1. The spiral packing 601 has punches 602 inside, which are distributed in a ring. The spiral packing 601 has an adhesion pattern 603 on its outer side wall.

[0034] See attached document Figure 1 Appendix Figure 3 and attached Figure 5 As shown, a spiral packing 601 is installed inside the first mounting cylinder 1. The spiral packing 601 is made of stainless steel and designed with a regular spiral structure to increase the gas-liquid contact area. Adhesion textures 603 are provided on the outer wall of the spiral packing 601 to enhance the adhesion of the liquid. Multiple perforations 602 are made in a ring shape inside the spiral packing 601 to ensure smooth gas-liquid flow and sufficient contact time. After the perforations 602 are made, the inner wall is polished to ensure that the inner wall of the hole is smooth, reduce the resistance damage caused by uneven gas-liquid distribution, and further improve the gas-liquid distribution. During the production process of the spiral packing 601, it is washed, dried, and sintered to improve the overall strength and thus increase the service life.

[0035] The bottom end of the first mounting cylinder 1 is engaged with the second mounting cylinder 7. The bottom end of the first mounting cylinder 1 is provided with a slot, and the bottom end of the second mounting cylinder 7 is provided with a block. The first mounting cylinder 1 and the second mounting cylinder 7 are engaged and connected.

[0036] The second mounting cylinder 7 is equipped with a mass transfer structure 5, which includes a first metal mesh 501, a second metal mesh 502, a third metal mesh 503, and rhomboid holes 504. The first metal mesh 501 is installed inside the second mounting cylinder 7. The second metal mesh 502 is provided at one end of the first metal mesh 501, and the third metal mesh 503 is provided on one side of the second metal mesh 502. The third metal mesh 503 is wavy. Rhomboid holes 504 are provided inside the first metal mesh 501, the second metal mesh 502, and the third metal mesh 503. The rhomboid holes 504 are arranged at equal intervals inside the first metal mesh 501, the second metal mesh 502, and the third metal mesh 503.

[0037] See attached document Figure 1-2 As shown, multiple sets of first metal mesh 501, second metal mesh 502, and third metal mesh 503 are installed inside the second mounting cylinder 7. The first metal mesh 501, second metal mesh 502, and third metal mesh 503 are made of metal mesh of various thicknesses. After pretreatment, they are rolled and punched into mesh strips with multiple diamond-shaped holes 504 evenly opened inside. Finally, they are pressed into a corrugated shape. Under the same separation conditions, the cost can be reduced by more than 30% compared with metal wire mesh corrugated packing. It is more suitable for separating systems with high separation difficulty, low pressure drop requirements, and corrosive substances. The opening of diamond-shaped holes 504 greatly improves the gas-liquid mass transfer rate, which can effectively improve the gas-liquid mass transfer efficiency. The gap between the first metal mesh 501, second metal mesh 502, and third metal mesh 503 can further reduce the pressure drop and reduce the generation of wall flow.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
