Description

Technical Field

[0001] This application relates to the field of tower internals technology, and specifically to a tower internals device suitable for fixed-side sampling ports. Background Technology

[0002] Distillation equipment plays a crucial role in chemical research. For the separation of complex systems, in order to save on equipment investment and energy consumption, side-stream sampling can often be used for certain substances. That is, the required substance is sampled at the top of the column, and one or more sampling outlets are set in the rectification or stripping section to sample other required substances.

[0003] In distillation columns with side-stream feeds, the location of the side-stream feed not only affects the composition of the feed itself but also significantly influences the composition of the feed from other outlets. Therefore, the selection of the side-stream feed location is particularly important. In the initial stages of process development, pilot-scale equipment, i.e., equipment with a small column diameter, is often used for research. To select the optimal side-stream feed location, the common practice is to pre-select several locations in the column as side-stream feed ports. This approach can meet the needs of scientific research and development to some extent, but due to limitations in equipment manufacturing and other factors, it is often impossible to accurately select a suitable side-stream feed location or to adapt to the need to change the side-stream feed location when changing to different materials.

[0004] This application proposes to design an adjustable tower internal device that can be applied to a fixed side sampling port, thereby ensuring that a suitable side sampling position can be selected and adapting to the need to change the side sampling position when changing different materials; after a detailed search, no relevant technical solutions were found.

[0005] In summary, a new technical solution is needed to address the aforementioned technical problems. Utility Model Content

[0039] The following is in conjunction with the appendix Figure 1 — Figure 16 The specific embodiments of this utility model will be described in detail below. It should be noted that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0040] Example 1:

[0041] This embodiment provides a column internals device suitable for a fixed side sampling port, including two guide rails 1. A partition plate 2 is mounted on each guide rail 1 to cooperate with it. The guide rails 1 are used to install and fix the partition plate 2. Preferably, depending on the sealing requirements, sealing material can be installed at the corresponding positions of the guide rails 1 or partition plate 2 at the contact points between the guide rails 1 and the partition plate 2 to ensure that the side-sampled liquid phase is not affected by liquid phases from other locations. The two guide rails 1 are welded parallel to each other on the wall of the distillation column 3. The distance between the two guide rails 1 ensures that the partition plate 2 can be inserted into the distillation column 3 along the guide rails 1. Multiple material holes 4 are spaced apart. In operation, one material hole 4 engages with the receiving plate 5, while the remaining material holes 4 are equipped with baffles 6 that engage with them. The baffles 6 can be fully embedded in the material holes 4. When it is necessary to change the side sampling position, the original material hole 4 is blocked by the baffles 6, the baffle 6 at the desired side sampling position is removed, and the receiving plate 5 is adjusted to the new position that engages with the material hole 4. This application only requires a discharge port 7 at the lowest end of the rectification section or stripping section. By adjusting the position of the receiving plate 5, the function of side sampling liquid phase at different positions can be realized.

[0042] Specifically: the isolation plate 2 includes an isolation main plate 9, and isolation side plates 10 perpendicular to the isolation main plate 9 are provided on both sides of the isolation main plate 9, forming a U-shaped semi-enclosed structure. Multiple material holes 4 are spaced apart on the isolation side plates 10. An upper sealing plate 11 is provided at the top of the isolation main plate 9 and the isolation side plates 10, and a lower sealing plate 12 is provided at the bottom of the isolation main plate 9 and the isolation side plates 10. Preferably, the isolation main plate 9, the isolation side plates 10, the upper sealing plate 11, and the lower sealing plate 12 are integrally formed. The upper sealing plate 11 prevents liquid phase from entering the isolation plate 2 from the top, and the lower sealing plate 12 retains the side-sampled liquid phase within the isolation plate 2. Preferably, the material holes 4 are rectangular or square holes, and the rectangular or square holes taper along the direction between the two isolation side plates 10, i.e., as shown... Figure 3 As shown, when a rectangular or square hole extends along the depth direction, its length and width gradually decrease; for example... Figure 4 , Figure 5 As shown, the four contact surfaces 8 on the baffle 6 that cooperate with the material hole 4 are all inclined slopes. The cooperation between the opening and the slopes ensures that the baffle 6 can be completely embedded in the material hole 4, while the baffle 6 does not enter the interior of the isolation plate 2 when it is squeezed by external force.

[0043] The guide rail 1 includes a guide rail main board 13, with guide rail side plates 14 vertically arranged on both sides of the guide rail main board 13. The length of the guide rail side plates 14 is equal to the length of the isolation side plate 10. The distance between the two guide rail side plates 14 is equal to the thickness of the isolation side plate 10. The guide rail side plates 14 contact the baffle 6. The guide rail main board 13 and the guide rail side plates 14 are integrally formed. The width of the guide rail side plates 14 is sufficient to block part of the area of ​​the material hole 4 on the isolation plate 2, thereby fixing the baffle 6 to the material hole 4. Another type of guide rail 1 includes a guide rail main board 13, with guide rail side plates 14 arranged on both sides of the guide rail main board 13. The guide rail side plates 14 contact the baffle 6. The guide rail side plates 14 and the guide rail main board 13 are integrally formed. The angle between the guide rail side plates 14 and the guide rail main board 13 is an acute angle. The width of the guide rail side plates 14 is... The thickness of the two guide rail side plates 14 is greater than the thickness of the isolation side plate 10. The distance between the two sides of the guide rail side plates 14 that are not connected to the guide rail main plate 13 is less than or equal to the thickness of the isolation side plate 10. When it is less than, more specifically, it is less than the thickness of the isolation side plate 10 by 1-3 mm. The specific acute angle is set according to the thickness of the isolation side plate 10 and is not specifically limited. The two guide rail side plates 14 can block part of the area of ​​the material hole 4 on the isolation plate 2. The baffle 6 is fixed on the material hole 4 of the isolation plate 2 by using the acute angle design (recessed end) between the guide rail side plate 14 and the guide rail main plate 13. That is, the isolation plate 2 is clamped by the two guide rail side plates 14, thereby fixing the baffle 6 on the material hole 4. The acute angle between the guide rail side plate 14 and the guide rail main plate 13 can better achieve the clamping of the baffle 6.

[0044] The liquid receiving tray 5 includes an annular liquid receiving groove 15. An air vent 16 is provided in the middle of the annular liquid receiving groove 15, and multiple liquid draining holes 17 are provided on the outer side of the air vent 16 on the annular liquid receiving groove 15. A baffle plate 18 is provided above the air vent 16. Preferably, the baffle plate 18 is an umbrella-shaped baffle plate. An overflow weir 19 is provided on the annular liquid receiving groove 15 at the edge of the air vent 16. A liquid overflow port 20 is provided on one side of the annular liquid receiving groove 15, and the liquid overflow port 20 cooperates with the material hole 4. The width of the liquid overflow port 20 is equal to the distance between the outermost edges of the two guide rails 1. The inner two overflow port contact surfaces 21 of the liquid overflow port 20 contact the outer surface of the guide rail 1. When the liquid receiving tray 5 is installed, the upper edge 22 of the liquid overflow port (i.e., The surface of the annular receiving tank 15 coincides with the lower edge 23 of the material hole, ensuring that the liquid phase flows smoothly into the isolation plate 2. The aforementioned gas riser 16 is the channel for the gas phase in the distillation column 3. Depending on the column diameter and the gas phase distribution, there may be one or more gas risers 16. The baffle plate 18 is used to block the liquid phase flowing down from the upper layer and guide the liquid phase into the annular receiving tank 15. The interior of the annular receiving tank 15 is an overflow weir 19, which ensures that there is a certain liquid level in the annular receiving tank 15. The bottom of the annular receiving tank 15 is provided with a downcomer 17 to evenly distribute the liquid phase into the lower packing. The liquid overflow port 20 is the outlet of the annular receiving tank 15. The material on the annular receiving tank 15 flows into the isolation plate 2 through the liquid overflow port 20, completing the side sampling.

[0045] The working principle of this embodiment is as follows: the guide rail 1 is fixed to the inner wall of the distillation column 3 by welding or other means. The isolation plate 2 is installed on the guide rail 1. A material hole 4 that matches the liquid receiving tray 5 is reserved as required. Corresponding baffles 6 are installed in other material holes 4. The baffles 6 are pressed onto the isolation plate 2 by the guide rail 1. The bottom of the annular liquid receiving tank 15 is supported by packing. The gas phase at the bottom of the distillation column 3 rises to the upper part of the liquid receiving tray 5 through the gas riser 16. After mass transfer with the liquid, it continues to rise. The liquid flows down from the top of the column or the upper tray. The baffle plate 18 is used to block the liquid phase flowing down from the upper layer and guide the liquid phase into the annular liquid receiving tank 1. Within 5, the overflow weir 19 ensures a certain liquid level in the annular receiving tank 15, and the downcomer 17 is used to evenly distribute the liquid phase into the lower packing. The material on the annular receiving tank 15 flows into the isolation plate 2 through the liquid overflow port 20 and the material hole 4 (specifically, it flows into the closed space formed by the isolation side plate 10, the isolation main plate 9, the upper sealing plate 11, the lower sealing plate 12, and the inner wall of the distillation column 3), and is side-collected through the discharge port 7. When it is necessary to change the side-collection position, the original material hole 4 is blocked by the baffle 6, the baffle 6 at the side-collection position is removed, and the receiving plate 5 is adjusted to a new position that matches the new material hole 4.

[0046] Example 2:

[0047] The difference between this embodiment and embodiment one is that the isolation side plate 10 in this embodiment has a single material hole 4 instead of multiple holes spaced apart. The material hole 4 is a rectangular hole and cooperates with the liquid receiving tray 5. During operation, a perforated baffle 24 is provided at the position where the material hole 4 cooperates with the liquid receiving tray 5, and multiple baffles 6 are installed sequentially in the other material holes 4 to cooperate with it. The perforated baffle 24 can both support the stability of the baffles 6 in the entire material hole 4 and ensure overflow. The advantage of the material hole 4 being a rectangular hole and having a continuous material hole 4 is that the position of the liquid receiving tray 5 can be changed more flexibly.

[0048] Preferably, such as Figure 8 As shown, the two long sides of the rectangular hole taper along the opening direction, while the short side does not shrink; that is, the hole diameter decreases towards the inner side of the isolation side plate 10, as shown. Figure 9 , Figure 10 As shown, the two left and right contact surfaces 25 on the baffle 6 that cooperate with the material hole 4 are inclined slopes, and the upper and lower contact surfaces 26 that contact the baffle 6 or the material hole 4 are flat. The fit between the constriction and the inclined surfaces ensures that the baffle 6 can be completely embedded in the material hole 4, while the baffle 6 does not enter the interior of the isolation plate 2 when subjected to external pressure. The hollow baffle 24 includes a hollow body 27. The two hollow baffle contact surfaces 28 on the hollow body 27 that cooperate with the long side of the material hole 4 are inclined slopes, and the upper and lower contact surfaces 29 on the hollow body 27 that contact the material hole 4 or the baffle 6 are flat. A through hole 30 is opened in the middle of the hollow body 27.

[0049] In this embodiment, when it is necessary to change the side sampling position, the original hollow baffle 24 is replaced by the baffle 6. The baffle 6 at the side sampling position is removed and replaced with the hollow baffle 24. At the same time, the liquid receiving plate 5 is adjusted to a new position that matches the new hollow baffle 24.

[0050] Example 3:

[0051] This embodiment provides a specific application scenario, such as... Figure 15 The diagram shows the installation. In a more specific embodiment, the distillation column 3 with a diameter of DN100 is installed in the rectification section. The distillation column 3 is a random packing column with a rectification section length of 1000mm. The guide rail 1 and the isolation plate 2 are 950mm long. The diameter of the air riser hole 16 of the liquid receiving tray 5 is 50mm. The overflow weir 19 is 10mm high. Six downcomer holes 17 are evenly distributed on the annular liquid receiving tank 15. A material hole is opened on the isolation plate 2. The baffle 6 is 15mm high. The position of the liquid receiving tray 5 changes every 15mm. Therefore, the side sampling position can be changed at 15mm intervals. The side sampling liquid from all positions is collected at the bottom of the isolation plate 2 and is discharged from the bottom outlet 7.

[0052] In summary, due to the adoption of the above technical solution, this application has the following advantages:

[0053] 1. A discharge port is set at the lowest end of the rectification section or stripping section. The position of the liquid receiving plate in this application can be adjusted. With the adjustment of the position of the liquid receiving plate, it cooperates with the corresponding material port to realize the function of side sampling of liquid phase at different positions.

[0054] 2. This application can be applied to the renovation of old towers, making full use of existing equipment and saving on equipment renovation costs;

[0055] 3. This application is easy to install and can quickly meet the needs of changing the side sampling position.
