Description

Technical Field

[0002] In chemical processes such as petrochemicals, packing supports are an indispensable part of packed tower equipment. The support structure of the packing support is crucial to the performance and lifespan of the entire packed tower reactor. A good support structure ensures the effective utilization of the packing catalyst, avoids localized hot spots or gas flow short-circuiting, thereby improving reaction efficiency. Traditional packing supports have fixed support structures and packing volumes. When different chemical reactions need to be carried out and the packing needs to be replaced, it is impossible to guarantee that the replacement support structure and packing volume will perfectly match the chemical reaction to be carried out. For example, when replacing the packing, it may be necessary to reduce the porosity to ensure support strength, which may lead to a significant increase in system pressure drop and energy consumption.

[0003] Therefore, how to provide a packing support device suitable for various packing masses and volumes is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0024] This application provides a modular packing support device for packed towers, which has a simple structure and is easy to disassemble and assemble, and facilitates adjustment of support strength and porosity as the packing changes.

[0025] refer to Figure 1 , Figure 1 This is a schematic diagram of a modular packing support device according to an exemplary embodiment of this application. The modular packing support device may include: a first support ring plate 1, an inner cylinder 2, a wire mesh layer 3, a grating plate 4, a grating support plate 6, and a support round steel bar 7. (Reference) Figure 2 , Figure 2 Is it like this? Figure 1 A detailed view of node I of the modular packing support device is shown, illustrating the connection structure between the first support ring plate 1 and the packed tower reactor and inner cylinder 2. The outer ring end of the first support ring plate 1 is welded to the inner wall of the packed tower reactor, and the bottom of the inner ring end of the first support ring plate 1 is welded to the top of the inner cylinder 2. Figure 2 As shown, the inner diameter of the first support ring plate 1 is the same as the inner diameter of the inner cylinder 2. (Reference) Figure 3 , Figure 3 Is it like this? Figure 1 The schematic diagram of the cross-sectional view AA of the modular packing support device shows the connection structure of the supporting round steel bars 7, the grating support plates 6, and the inner cylinder 2. The supporting round steel bars 7 are arranged in a grid pattern and welded to the bottom of the inner cylinder 2. The grating support plates 6 are arranged on the supporting round steel bars 7 and have the same grid pattern as the supporting round steel bars 7. The bottom of the grating support plates 6 is welded to the supporting round steel bars 7, and the side ends are welded to the inner cylinder 2. (Return to Reference) Figure 1 ,like Figure 1As shown, the grating plate 4 is arranged above the grating support plate 6 and welded to the inner cylinder 2. The wire mesh layer 3 is arranged above the grating plate 4 and is turned upward along the cylinder wall of the inner cylinder 2. The turned-up portion of the wire mesh layer 3 is fixed by a wire mesh fixing device arranged circumferentially along the cylinder wall of the inner cylinder 2. Based on the above structure, this application provides a modular packing support device that is easy to disassemble and assemble. When only the packing added to the inner cylinder 2 needs to be replaced, only the wire mesh layer 3 can be removed, and then the wire mesh layer 3 and the packing can be replaced. When the overall structure of the support device needs to be adjusted according to the packing (for example, when the packing mass or packing volume changes significantly), the inner cylinder 2 and the other components can be disassembled together from the weld between the first support ring plate 1 and the inner cylinder 2, replaced with a support structure with suitable support strength and capacity, and then re-welded to the first support ring plate 1, thereby achieving a suitable support structure for different packing masses and volumes.

[0026] In a preferred embodiment of this application, the modular filler support device provided in this application further includes a second support ring plate 5. (See reference...) Figure 4 , Figure 4 This is a schematic diagram of the structure of a modular filler support device provided according to another exemplary embodiment of this application, such as... Figure 4 As shown, the modular filler support device may include: a first support ring plate 1, an inner cylinder 2, a wire mesh layer 3, a grating plate 4, a second support ring plate 5, a grating support plate 6, and a support round steel bar 7, wherein the structure of the first support ring plate 1, the inner cylinder 2, the wire mesh layer 3, the grating plate 4, and the support round steel bar 7 is as described in the aforementioned embodiment. (Reference) Figure 5 , Figure 5 Is it like this? Figure 4 The detailed view of node II of the modular filler support device shown illustrates the connection structure of the grating plate 4, the second support ring plate 5, the grating support plate 6, and the support round steel 7. The second support ring plate 5 is located on the top outer periphery of the grating support plate 6, and a space is reserved on the top of the grating support plate 6 near the inner cylinder 2 to accommodate the second support ring plate 5. The outer ring end of the second support ring plate 5 is welded to the inner cylinder 2, and the upper surface of the second support ring plate 5 is at the same level as the upper surface of the grating support plate 6. On one hand, by using the grating support plate 6 in conjunction with the second support ring plate 5 arranged horizontally along the circumference to support the grating plate 4, local flatness problems that may be caused by large gaps between the grating support plate 6 and the grating plate 4 can be avoided. On the other hand, the second support ring plate 5 provides a platform and contact point for welding between the grating plate 4 and the inner cylinder 2, facilitating welding of the grating plate 4 by technicians. (Reference) Figure 6 , Figure 6 Is it like this? Figure 4 The schematic diagram of the cross-sectional view BB of the modular packing support device shown illustrates the connection structure between the grating plate 4, the inner cylinder 2, and the second support ring plate 5. Figure 5 and Figure 6As shown, when welding the grating plate 4, the technician can place the grating plate 4 above the grating support plate 6 and the second support ring plate 5, and start welding from the contact point between the second support ring plate 5, the grating plate 4, and the inner cylinder 2. In a preferred embodiment of this application, the second support ring plate 5 has multiple through holes for fluid to pass through. These through holes reduce the problem of fluid medium flow obstruction caused by the placement of the second support ring plate 5, thereby avoiding a reduction in reaction efficiency. See also... Figure 7 , Figure 7 Is it like this? Figure 5 The schematic diagram of the cross-sectional view CC of the modular filler support device shown in the figure details the connection structure between the support round steel 7 and the grid support plate 6, and shows the second support ring plate 5.

[0027] In a preferred embodiment of this application, the wire mesh fixing device may include a wire mesh fixing block 8, a hexagonal bolt 9, and a nut 10, such as Figure 8 As shown. Preferably, the shank of the hex bolt 9 passes through the inner cylinder 2 and the head of the hex bolt 9 is pre-welded firmly to the outer wall of the inner cylinder 2, so that the wire mesh layer 3 can be removed simply by tightening or loosening the nut 10 inside the inner cylinder 2.

[0028] In a preferred embodiment of this application, the grating plate 4 has a regular square grid structure formed by welding. Such a structure does not hinder the passage of gas or liquid medium through the packing support device, so that the medium can generate uniform flow pressure when passing through, while providing a certain support for the packing.

[0029] In a preferred embodiment of this application, the wire mesh layer 3 comprises 2-3 layers of wire mesh. The more layers of wire mesh layer 3, the less packing material is lost; however, too many layers of wire mesh layer 3 may obstruct the flow of fluid media, reducing reaction efficiency. Therefore, setting 2-3 layers of wire mesh layer 3 helps to ensure reaction efficiency while minimizing packing material loss. For example, a 2-layer wire mesh layer 3 can be provided, including an upper wire mesh and a lower wire mesh. The upper and lower wire mesh can be formed by folding a single wire mesh, or they can be composed of two different wire meshes. Those skilled in the art can choose according to the specific circumstances. In a preferred embodiment of this application, the wire mesh layer 3 is made of stainless steel, which has strong corrosion resistance and is suitable for most packed reactors. When the reaction conditions are more extreme or the packing catalyst and media are more corrosive, the wire mesh layer 3 can be made of a more corrosion-resistant material (such as titanium alloy) to cope with extreme conditions, provided that the wire mesh material does not affect the original chemical reaction.
