Description

A high-efficiency, low-pressure-drop corrugated packing Technical Field

[0001] This utility model relates to the field of corrugated packing technology, and in particular to a high-efficiency, low-pressure-drop corrugated packing. Background Technology

[0002] According to a metal wire mesh corrugated packing mechanism disclosed in Chinese Publication No. CN205517794U, it includes packing layers, spacer wires, and connecting strips. Multiple packing layers are stacked sequentially, with spacer wires woven from metal fibers between adjacent layers. One end of the connecting strip has a fixing block, and the other end passes through the bottom of the lowest packing layer, sequentially through the corresponding spacer wires and packing layers, and exits from the top, where it is locked by a nut. The surface of the locked nut is flush with the surface of the uppermost packing layer. This design offers advantages such as simple structure, easy manufacturing, high overall strength, and good performance.

[0003] The wire mesh corrugated packings described above and in the prior art have small mesh pores and complex structures, making them easily clogged by impurities, dirt, and polymers in the materials. However, the small cylindrical wire mesh corrugated packings described above and in the prior art use corrosion-resistant metal wires such as stainless steel wire to bind individual small cylindrical wire mesh corrugated packings together along the axial direction to form an integral unit, making subsequent cleaning of the wire mesh corrugated packings more difficult. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing wire mesh corrugated packings, which are difficult to clean later, and to propose a high-efficiency, low-pressure-drop corrugated packing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency, low-pressure-drop corrugated packing, comprising a base frame, six fixed columns on the top surface of the base frame, two claws on the top surface of each of the six fixed columns, a top frame on the top of the six fixed columns, a first packing on the top of the base frame, a second packing on the top of the first packing, a third packing on the top of the second packing, binding straps on the outside of the first, second, and third packings, and six slots on the surface of the top frame.

[0006] Preferably, the six fixed columns are arranged in a circular array on the top surface of the base frame, and the fixed columns and the base frame are integrally formed.

[0007] Preferably, the first packing, the second packing, and the third packing are stacked on one side of the bottom surface of the base frame, and the first packing, the second packing, and the third packing are all located in the middle of the six fixed columns.

[0008] Preferably, the first packing, the second packing, and the third packing are all wire mesh corrugated packing.

[0009] Preferably, the positions of the three binding straps correspond one-to-one with the first packing, the second packing, and the third packing, and the binding straps are integrally formed with the fixing column.

[0010] Preferably, all six fixing posts are integrally formed with the two claws on the top surface.

[0011] Preferably, the positions of the six slots correspond one-to-one with the positions of the six fixing posts, and the six fixing posts penetrate the six slots on the surface of the top frame and are fixed with claws.

[0012] Beneficial effects

[0013] In this invention, during cleaning, the claws on the fixed column are pressed to converge towards the center, allowing the top frame to detach from the fixed column. Once the top frame is detached, the first, second, and third packing layers in the middle of the fixed column can be removed, and any blockages can be cleared. Compared to integrated wire mesh corrugated packing, modular wire mesh corrugated packing is relatively independent and smaller in size, making it easier to clean and maintain. Furthermore, when one layer of corrugated packing is severely blocked or damaged, only the severely blocked or damaged layer needs to be replaced, rather than the entire packing. This reduces the maintenance required and solves the problem of difficult subsequent cleaning of wire mesh corrugated packing. Attached Figure Description

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. 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.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0022] Specific Implementation Example 1:

[0023] Referring to Figures 1-4, a high-efficiency, low-pressure-drop corrugated packing includes a base frame 1. The top surface of the base frame 1 has six fixing posts 3, each with two clamping claws 9. A top frame 2 is located on top of the six fixing posts 3. A first packing 5 is located on top of the base frame 1, a second packing 6 is located on top of the first packing 5, and a third packing 7 is located on top of the second packing 6. The first packing 5, second packing 6, and third packing 7 are all equipped with binding straps 4. The surface of the top frame 2 has six slots 8. The six fixing posts 3 are arranged in a circumferential array on the top surface of the base frame 1, and the fixing posts 3 are integrally formed with the base frame 1. The first packing 5, second packing 6, and third packing 7 are... The third packing 7 is stacked on one side of the bottom surface of the base frame 1, and the first packing 5, the second packing 6 and the third packing 7 are all set in the middle of the six fixed posts 3. The first packing 5, the second packing 6 and the third packing 7 are all wire mesh corrugated packing. The positions of the three binding straps 4 correspond one-to-one with the first packing 5, the second packing 6 and the third packing 7, and the binding straps 4 are all integrally formed with the fixed posts 3. The six fixed posts 3 are all integrally formed with the two claws 9 on the top surface. The positions of the six slots 8 correspond one-to-one with the positions of the six fixed posts 3, and the six fixed posts 3 penetrate into the six slots 8 on the surface of the top frame 2 and are fixed with the claws 9.

[0024] The base frame 1 provides a stable support foundation. The top frame 2 cooperates with the base frame 1 to form the upper and lower boundaries of the packing material, limiting and protecting it. The surfaces of the base frame 1 and top frame 2 are equipped with a grid structure to limit and protect the packing material after installation, preventing displacement or deformation due to airflow or other factors during operation. Six fixed posts 3 are arranged in a circumferential array on the top surface of the base frame 1 and are integrally formed with it. The top of each fixed post 3 has two claws 9 that cooperate with the slots 8 of the top frame 2 to secure it. The fixed posts 3 also support and fix the restraint straps 4. The restraint straps 4, through their own elasticity (the base frame 1, fixed posts 3, top frame 2, claws 9, and restraint straps 4 are all made of plastic), apply a certain restraining force to the packing material, maintaining its stable position and shape between the fixed posts 3, preventing loosening, displacement, or deformation under airflow impact, vibration, or other conditions. To ensure the regularity of the packing during operation, maintain its corrugated structure and porosity, guaranteeing uniform gas-liquid flow and good mass and heat transfer within the packing layer. The first packing layer 5, the second packing layer 6, and the third packing layer 7 are all wire mesh corrugated packing. The corrugated structure of the wire mesh corrugated packing increases the gas-liquid contact area, allowing the gas to flow in a tortuous manner within the packing layer, ensuring sufficient contact with the liquid, thereby achieving efficient mass and heat transfer. The corrugated shape and arrangement of the packing determine the gas-liquid flow path and contact method, affecting mass transfer efficiency and pressure drop. As the main site for gas-liquid contact and mass and heat transfer, its unique corrugated structure improves the uniformity and sufficiency of gas-liquid contact, achieving highly efficient separation and reaction processes while maintaining a low pressure drop and reducing energy consumption. The slots 8 are located on the surface of the top frame 2, corresponding one-to-one with the six fixed columns 3. When the claw 9 at the top of the fixed column 3 is inserted into the slot 8, the slot 8 limits and fixes the claw 9, preventing the top frame 2 from moving horizontally and ensuring a stable connection between the top frame 2 and the fixed column 3. The claw 9 is integrally formed with the fixed column 3 and is located at the top of the fixed column 3. When installing the top frame 2, the claw 9 is pushed outward so that it passes through the slot 8 of the top frame 2, and then the claw 9 is released. The claw 9 returns to its original shape under its own elasticity or structural design and is locked in the slot 8, thus fixing the top frame 2. When it is necessary to disassemble the top frame 2 for packing cleaning or maintenance, the claw 9 is pressed to converge towards the center, which allows the top frame 2 to detach from the fixed column 3. As a key component connecting the top frame 2 and the fixed column 3, it enables the quick installation and disassembly of the top frame 2, facilitating the cleaning and maintenance of the packing.

[0025] Specific Implementation Example 2:

[0026] Referring to Figures 1-4, a high-efficiency, low-pressure-drop corrugated packing, further based on the basic structure in Specific Embodiment 1, is described. Specifically, the high-efficiency, low-pressure-drop corrugated packing is installed inside a tower device, with gas flowing upwards from the bottom and liquid flowing downwards from the top. When the gas passes through the packing layer formed by the first packing 5, the second packing 6, and the third packing 7, the corrugated structure of these packings forces the gas to change its flow direction, creating turbulence. This turbulence allows the gas to fully contact the downward-flowing liquid on the surfaces of the first packing 5, the second packing 6, and the third packing 7, resulting in mass and heat transfer. The liquid forms a film on the packing surface and flows downwards along the corrugated surface, exchanging mass and heat with the gas.

[0027] During operation, the base frame 1 and fixed column 3 provide stable support, the restraint strap 4 ensures the orderly arrangement of the packing, and the top frame 2 limits and protects the packing. When cleaning or maintenance of the packing is required, remove the packing from the packing tower and press the claws 9 on the fixed column 3 to bring them together, detaching the top frame 2 from the fixed column 3. Then, the first packing 5, the second packing 6, and the third packing 7 in the middle of the fixed column 3 can be removed in sequence for cleaning or replacement of any blocked or damaged packing. After cleaning or replacement, reinstall the first packing 5, the second packing 6, the third packing 7, and the top frame 2 in the reverse order of removal for continued use.

[0028] In summary:

[0029] 1. During cleaning, press the claws 9 on the fixed column 3 to make the claws 9 converge in the middle, so that the top frame 2 can be detached from the fixed column 3. After the top frame 2 is detached, the first packing 5, the second packing 6 and the third packing 7 in the middle of the fixed column 3 can be taken out, and the blocked packing can be cleaned. Compared with the integrated wire mesh corrugated packing, the modular wire mesh corrugated packing is relatively independent and smaller in size, making it easier to clean and maintain. When one layer of corrugated packing is severely blocked or damaged, only the severely blocked or damaged wire mesh corrugated packing needs to be replaced, without replacing the whole packing. This reduces the maintenance of the bed board and solves the disadvantage of the wire mesh corrugated packing being difficult to clean later.
