Description

Technical Field

[0001] This utility model relates to the field of packing technology, specifically to a rectangular saddle ring packing. Background Technology

[0002] Packing materials have been widely used in unit operations such as distillation, absorption, and extraction in industries such as chemical, petroleum, pharmaceutical, and environmental protection. They are especially widely used in petroleum refining, purification, processing, and refining into gasoline, natural gas, rubber, and other main and by-products. Currently, the lower end of packed towers is mostly filled with Raschig rings, Pall rings, step rings, and rectangular saddle rings. Generally, the mass transfer and separation performance of packed towers mainly depends on the performance of the packing materials used.

[0003] Existing rectangular saddle ring packings have low mass transfer efficiency due to structural limitations. They are also prone to deformation after long-term use due to their small surface area and insufficient structural strength, which leads to a decrease in porosity. As a result, their overall performance is not ideal and there is room for improvement. Utility Model Content

[0016] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0017] According to an embodiment of the present invention, a rectangular saddle ring packing is provided.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1 and Figure 2As shown, a rectangular saddle ring packing according to an embodiment of the present invention includes an outer component 1 and a corrugated groove 10. Several sets of inner support rings 2 are installed on the inner side of the outer component 1, and the inner support rings 2 and the outer component 1 are concentric. Several sets of reinforcing ribs 3 are installed around each pair of inner support rings 2 and between the inner support rings 2 and the outer component 1. An outer thin sheet 5 is installed on the surface of the innermost inner support ring 2, and several sets of inner thin sheets 6 are symmetrically installed on the surface of the outer thin sheet 5. The outer component 1 is a ring-shaped metal part, preferably made of stainless steel or carbon steel, with a corrosion-resistant surface treatment, suitable for the acid and alkali environment inside chemical towers. Several sets of inner support rings 2 are evenly installed radially on its inner side. The inner support rings 2 are metal rings concentric with the outer component 1. The diameter gradually decreases from the outside to the inside, forming a concentric ring structure. It is fixed to the inner wall of the outer component 1 by full welding, ensuring no relative displacement between the inner support ring 2 and the outer component 1. The concentric structure allows for uniform radial force transmission, avoiding localized stress concentration. The outer component 1, inner support ring 2, and reinforcing rib 3 are integrally welded or formed using a stamping and welding combination process, ensuring the rigidity of the entire support structure and preventing deformation caused by long-term use, such as from media erosion or packing stacking. The concentrically positioned inner support ring 2 transmits the axial pressure borne by the outer component 1 radially to each ring layer, while the Z-shaped reinforcing rib 3 converts the radial pressure into circumferential tension through its own bending structure, achieving multi-dimensional force dispersion of "axial-radial-circumferential," compared to traditional... The rectangular saddle ring, without the inner support ring 2 structure, has improved compressive strength. The innermost set of inner support rings 2, i.e., the end face of the ring with the smallest diameter, is fixed to the outer thin sheet 5 by full welding. The outer thin sheet 5 is a circular metal sheet, and several sets of inner thin sheets 6 are symmetrically welded along the circumference. The inner thin sheets 6 are rectangular metal sheets, evenly distributed along the central axis of the outer thin sheet 5, forming a "central radial" structure. The surfaces of both the outer thin sheet 5 and the inner thin sheet 6 are roughened to enhance liquid adhesion. The welding angle between the inner thin sheet 6 and the outer thin sheet 5 is 45°, ensuring that the liquid can flow evenly along the surface of the thin sheet to the inner support ring 2, and then be transferred to the outer structure through the flow hole 7. The central area of ​​the traditional rectangular saddle ring is a hollow structure, which is prone to forming a medium "short circuit". However, insufficient mass transfer can be addressed by using the combination of outer thin sheet 5 and inner thin sheet 6 to fill the central hollow area, allowing the liquid to undergo secondary dispersion in the center and avoiding the "short circuit" phenomenon. The inner thin sheet 6 guides the liquid to flow from the center to the outer inner support ring 2, forming a "center-outer layer" mass transfer cycle with the outer corrugated strip 9 and flow groove 4, making the medium contact within the entire packing more uniform and further improving the mass transfer efficiency. The central radial thin sheet structure eliminates the central hollow dead zone of the traditional rectangular saddle ring, making the mass transfer efficiency evenly distributed across the entire packing cross section and avoiding the decrease in product purity caused by insufficient local mass transfer. The roughened thin sheets can increase the liquid residence time, allowing the liquid and gas to react fully, adapting to high-precision mass transfer requirements, such as the purification of pharmaceutical intermediates.

[0019] Please refer to Figure 1 and Figure 2As shown, an installation groove 8 is provided around the outer surface of the outer component 1. A rectangular installation groove 8 is provided around the outer surface of the outer component 1 along the circumferential direction, and the width is adapted to the corrugated strip 9. The corrugated strip 9 and the corrugated groove 10 on the outer side of the outer component 1 can break the medium flow boundary layer, reduce the boundary layer thickness, and make the liquid form a thin film flow on the surface, increasing the contact area with the gas. The flow hole 7 of the inner support ring 2 allows the gas to penetrate through each ring layer and achieve reverse or cross-flow contact with the liquid, thereby improving the mass transfer coefficient.

[0020] Please refer to Figure 1 and Figure 3 As shown, several sets of corrugated strips 9 are installed around the inside of the mounting groove 8. The corrugated strips 9 are fixed inside the mounting groove 8 by full welding. The corrugated strips 9 are arc-shaped metal strips and the material is the same as that of the outer component 1.

[0021] Please refer to Figure 1 and Figure 3 As shown, a wave groove 10 is provided on the surface of the wave strip 9. The wave groove 10 is continuously provided on the surface of the wave strip 9 along the length direction. The wave strip 9 is evenly distributed along the circumference of the outer component 1, covering the entire outer surface of the outer component 1. The arc-shaped structure of the wave strip 9, the surface wave groove 10, and the through design of the flow hole 7, together with the flow groove 4 between the reinforcing ribs 3, form a multi-dimensional mass transfer interface of "outer surface-inner hole-channel". Compared with the traditional rectangular saddle ring, the total mass transfer area is increased.

[0022] Please refer to Figure 1 and Figure 2 As shown, several sets of flow holes 7 are evenly arranged around the surface of the inner support ring 2. Each set of inner support ring 2 has several sets of circular flow holes 7 evenly arranged along the circumference. The flow holes 7 penetrate the thickness of the inner support ring 2, allowing the medium between the inner support rings 2 to flow through each other, avoiding the formation of "dead zones" and reducing medium retention. The dimensions of the flow holes 7 are matched with those of the flow channels 4 and the corrugated channels 10 to ensure that small particles entrained in the medium can pass through smoothly and avoid blockage. At the same time, the concave and convex structure of the corrugated channels 10 can enhance liquid adhesion, extend liquid residence time, and improve mass transfer efficiency. The combination of corrugated strips 9, corrugated channels 10, flow holes 7, and flow channels 4 increases the effective mass transfer area per unit volume of packing, making it suitable for mass transfer unit operations such as distillation and absorption, and improving the processing capacity of the tower equipment. The multi-dimensional flow structure can optimize the medium flow field, reduce flow resistance, reduce pressure drop in the tower, and reduce the energy consumption of supporting equipment such as fans and pumps, meeting energy-saving requirements.

[0023] Please refer to Figure 1 and Figure 4As shown, the reinforcing rib 3 has a Z-shaped structure, and a flow groove 4 is provided between each pair of reinforcing ribs 3. Several sets of reinforcing ribs 3 are uniformly welded along the circumference between adjacent inner support rings 2 and between the outermost inner support ring 2 and the inner wall of the outer component 1. The reinforcing ribs 3 are Z-shaped metal strips to enhance the resistance to deformation. Both ends are fully welded to the corresponding inner support ring 2 or outer component 1. The reinforcing ribs 3 naturally form fan-shaped flow grooves 4 between each pair, which does not affect the flow of the medium and can disperse the axial and radial pressure through the Z-shaped structure. The design of the flow grooves 4 between each pair of reinforcing ribs 3 ensures the smooth passage of the medium, such as gas or liquid. The combination of inner support ring 2 and Z-shaped reinforcing ribs 3 forms a three-dimensional support network, which can improve the pressure borne by the packing stack and avoid the decrease in mass transfer efficiency due to deformation. Medium contact: gas rises from the bottom of the tower and liquid is sprayed from the top of the tower. When passing through the packing layer... The liquid forms a thin film flow along the corrugated strips 9 and corrugated grooves 10 of the outer component 1, and simultaneously enters the interior of the packing through the flow channel 4; Multi-dimensional mass transfer: The liquid achieves interlayer transfer through the flow holes 7 of the inner support ring 2, and forms cross-flow contact with the rising gas in the flow channel 4 and corrugated grooves 10. The outer thin plate 5 and inner thin plate 6 in the central region guide the liquid to disperse secondaryly, enhancing the contact; Pressure bearing capacity: When the packing is stacked, the axial pressure borne by the outer component 1 is dispersed in multiple dimensions through the inner support ring 2 and Z-shaped reinforcing ribs 3, ensuring structural stability, maintaining a stable porosity, and ensuring continuous and high mass transfer efficiency; Good support effect: The multi-dimensional support network improves the compressive strength, has strong resistance to deformation, and maintains a stable porosity over long-term use, adapting to the requirements of high stacking height; High conduction efficiency: The multi-dimensional mass transfer structure increases the effective mass transfer area, mass transfer coefficient, and tower equipment processing capacity, while reducing energy consumption.

[0024] Working principle: In actual use, the outer component 1 is equipped with multiple sets of inner support rings 2, and several sets of reinforcing ribs 3 are installed around the inner support rings 2 and the outer component 1, as well as between each pair of inner support rings 2. The inner support rings 2 and the multiple reinforcing ribs 3 can effectively disperse the pressure they bear, thereby improving the overall performance and support of the packing component. In addition, multiple sets of flow grooves 4 are also constructed between the reinforcing ribs 3 and the inner support rings 2. The flow grooves 4 can increase the overall contact area, thereby facilitating better transmission. At the same time, the corrugated strips 9 and the corrugated grooves 10 on the surface of the outer component 1 can further increase the contact area. Meanwhile, several sets of flow holes 7 are opened around the surface of the inner support rings 2. The flow holes 7 can reduce the probability of blockage during stacking, thereby improving the overall quality of use and facilitating better use. The device as a whole has the advantages of multiple supports, good support effect, and high transmission efficiency.
