Description

Technical Field

[0001] This invention relates to the technical field of filling elements for mass transfer equipment, and more particularly to a stainless steel corrugated packing. Background Technology

[0002] In core separation units of industrial processes such as petrochemicals, fine chemicals, oil refining, air separation, and environmental desulfurization, packing, as the core mass and heat transfer component of tower equipment, directly determines the operating efficiency, energy consumption level, and product quality of unit operations such as distillation, absorption, and desorption. Compared with traditional random packing, structured packing has advantages such as low pressure drop, high efficiency, and large throughput, and is therefore widely used in separation units in petrochemicals, oil refining, and chemicals. Corrugated structured packing is favored for its unique high-efficiency characteristics.

[0003] During long-term industrial use, the structural drawbacks of existing traditional corrugated structured packings have become increasingly apparent, severely restricting the long-term stable and efficient operation of tower equipment. Currently, most corrugated structured packings on the market are integral fixed structures, with each corrugated plate fixed by welding, riveting, or integral pressing. This makes it inconvenient to disassemble the corrugated plates. Over time, the corrugated plates not only accumulate scale on the surface, but the internal channels of the packing are also prone to blockage, reducing the mass and heat transfer efficiency of the gas and liquid phases in structured packings.

[0004] Therefore, in order to address the application defects of existing products and improve the mass transfer stability of packing, innovative designs are needed based on the existing corrugated packing. Summary of the Invention

[0005] The technical problem to be solved by this application is to provide a stainless steel corrugated packing material that addresses the shortcomings of the prior art. The packing material has a simple structure and reasonable design, and the corrugated plates are easy to disassemble, replace or repair. At the same time, the first plate and the second plate are locked together by connecting bolts, and the corrugated plates between them are interlaced, which can effectively increase the surface area of ​​the packing material and form channels between the first plate, the second plate and the corrugated plates to facilitate the flow of materials.

[0006] To solve the above-mentioned technical problems, the technical solution adopted in this application is: A stainless steel corrugated packing includes: a first plate and a second plate, the second plate being disposed on the outer side of the first plate, windows being provided on both the first and second plates, mounting grooves being provided on the facing surfaces of the first and second plates, inserting strips being disposed in the mounting grooves, support plates being disposed on the surface of the inserting strips, corrugated plates being fixed on the surface of the support plates, and connecting bolts being disposed between the first and second plates, with a nut installed at one end of the connecting bolts.

[0007] Preferably, the windows are arranged vertically through the first plate and the second plate, and the windows are distributed at equal intervals on the first plate and the second plate.

[0008] Preferably, the mounting groove horizontally penetrates the first plate and the second plate, and the bottom width of the mounting groove is greater than the opening width.

[0009] Preferably, the insert strip is embedded in the mounting groove, and the insert strip is slidably connected to the first plate and the second plate respectively through the mounting groove.

[0010] Preferably, the corrugated plates are distributed at equal intervals on the outer sides of the first plate and the second plate.

[0011] Preferably, the corrugated plates on the outer sides of the first plate and the second plate are staggered, and the corrugated plates correspond to the windows.

[0012] Preferably, the corrugated plate has corrugations, which are one of the following: sinusoidal corrugations, semi-elliptical corrugations, herringbone corrugations, umbrella-shaped arc corrugations, or circular corrugations.

[0013] This application has the following advantages compared with the prior art: 1. This application has a simple structure, reasonable design, and is easy to implement and use.

[0014] 2. The corrugated plate of this application is installed or disassembled on the first plate and the second plate through the cooperation between the insert strip and the mounting groove, which facilitates the disassembly, replacement or maintenance of the corrugated plate. This solves the technical shortcomings of traditional integral packing that cannot be locally operated and maintained, simplifies the maintenance operation process, effectively reduces the operation and maintenance cost, and significantly shortens the downtime for equipment maintenance.

[0015] 3. The first plate and the second plate of this application are locked together by connecting bolts. The corrugated plates between the two are interlocked, which can effectively increase the surface area of ​​the packing and form channels between the first plate, the second plate and the corrugated plates, facilitating the flow of materials and improving the mass transfer stability of the packing.

[0016] In summary, this invention facilitates the disassembly and replacement of the corrugated plates, effectively solving the technical shortcomings of traditional integral packings that cannot be locally maintained; the first plate and the second plate are locked and fixed, so that the corrugated plates between the plates are arranged in an alternating structure, which can effectively increase the surface area of ​​the packing and improve the mass transfer stability of the packing.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments thereof.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0023] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0024] according to Figures 1-5 As shown, the present invention provides a technical solution: a stainless steel corrugated packing, comprising: a first plate 1 and a second plate 2, the second plate 2 being disposed on the outer side of the first plate 1, windows 3 being provided on both the first plate 1 and the second plate 2, mounting grooves 4 being provided on the facing surfaces of the first plate 1 and the second plate 2, inserting strips 5 being disposed in the mounting grooves 4, support plates 6 being disposed on the surface of the inserting strips 5, corrugated plates 7 being fixed on the surface of the support plates 6, and a connecting bolt 8 being disposed between the first plate 1 and the second plate 2, with a nut 9 installed at one end of the connecting bolt 8.

[0025] When a single corrugated plate 7 experiences scaling, blockage, media corrosion, plate deformation, damage, aging, or localized mass transfer deterioration, fluid channel disorder, or material and dirt accumulation, affecting gas-liquid flow and mass and heat transfer effects, the corrugated plate 7 can be disassembled on the first plate 1 and the second plate 2 through the cooperation between the insert strip 5 and the mounting groove 4. This solves the technical shortcoming of traditional integral packing that cannot be locally maintained.

[0026] After the corrugated plates 7 are installed on the first plate 1 and the second plate 2 respectively, the connecting bolts 8 are passed through the first plate 1 and the second plate 2. The first plate 1 and the second plate 2 are locked together by the connecting bolts 8. The corrugated plates 7 between the two are interlaced, which can effectively increase the surface area of ​​the packing and form a channel between the first plate 1, the second plate 2 and the corrugated plates 7, which facilitates the flow of materials and improves the mass transfer stability of the packing.

[0027] In this example, the windows 3 are arranged longitudinally through the first plate 1 and the second plate 2, and the windows 3 are equally spaced on the first plate 1 and the second plate 2, so that the fluid can flow through the windows 3 between the first plate 1 and the second plate 2.

[0028] In this example, the mounting groove 4 horizontally penetrates the first plate 1 and the second plate 2. The bottom width of the mounting groove 4 is greater than the opening width. The insert strip 5 is embedded in the mounting groove 4. The insert strip 5 is slidably connected to the first plate 1 and the second plate 2 through the mounting groove 4, which is conducive to the insert strip 5 being installed on the first plate 1 and the second plate 2 through the mounting groove 4. The small opening of the mounting groove 4 can prevent the insert strip 5 from falling out of the mounting groove 4.

[0029] In this example, the corrugated plates 7 are distributed at equal intervals on the outer sides of the first plate 1 and the second plate 2. The corrugated plates 7 on the outer sides of the first plate 1 and the second plate 2 are staggered. The corrugated plates 7 correspond to the windows 3, which can increase the surface area of ​​the filler and form a channel between the first plate 1, the second plate 2 and the corrugated plates 7 to facilitate the flow of materials.

[0030] In this example, the corrugated plate 7 has corrugations, which can be sinusoidal, semi-elliptical, herringbone, umbrella-shaped, or circular. The corrugations allow for sufficient flow of the gas and liquid phases through the packing channel, significantly increasing the gas-liquid contact surface area. The smooth transitions of the corrugations without sharp edges effectively reduce gas flow resistance and overall pressure drop, minimize material fouling, and enhance mass and heat transfer efficiency.

[0031] Working principle: First, the corrugated plate 7 is installed or removed from the first plate 1 and the second plate 2 through the cooperation between the insert strip 5 and the mounting groove 4, so as to facilitate the disassembly, replacement or maintenance of the corrugated plate 7. After the corrugated plate 7 is installed on the first plate 1 and the second plate 2 respectively, the connecting bolt 8 is passed through the first plate 1 and the second plate 2, and the first plate 1 and the second plate 2 are locked together by the connecting bolt 8. The corrugated plates 7 between the two are interlaced, which can effectively increase the surface area of ​​the filler and form a channel between the first plate 1, the second plate 2 and the corrugated plate 7 to facilitate the flow of materials.

[0032] The above description is merely an embodiment of this application and does not constitute any limitation on this application. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of this application shall still fall within the protection scope of the technical solution of this application.
