Description

Technical Field

[0001] This utility model relates to the field of solvent removal tower technology, and specifically to a solvent removal tower. Background Technology

[0002] The upper section of the packed tower is a desolventizing and drying tower section, which is filled with packing. There is a vacuum pipe at the top of the tower to draw a vacuum and reduce the pressure inside the tower. The lower section has a direct steam nozzle, which allows oil to enter from the top and exit from the bottom, and direct steam to enter from the bottom and exit from the top, to process the oil. However, during the processing, since the packing is mostly flat and structured packing, the surface tension of the oil is relatively high. When the oil passes through the structured packing, the liquid flow rate will be small, resulting in low production efficiency. Utility Model Content

[0025] Example 1

[0026] like Figure 1-4 As shown, the present invention proposes a solvent extraction tower, which includes a tower body 1, a connecting rod 2, a support plate 3, and a support frame 4.

[0027] The support frame 4 is installed on the inner side of the tower body 1 and near the flange at the bottom of the tower body 1;

[0028] There are multiple support plates 3, which are located on the inner side of the tower body 1 and installed on the top of the support frame 4, and the multiple support plates 3 are stacked.

[0029] The connecting rod 2 is installed in the middle of multiple support plates 3 and connects the multiple support plates 3 into a whole in use. The bottom end of the connecting rod 2 and below the support plates 3 is provided with a limiting plate 8. The diameter of the limiting plate 8 is larger than the diameter of the middle part of the support plate 3. It is used to limit the position of the lowermost support plate 3 on the connecting rod 2 during use. The multiple support plates 3 and the support frame 4 can be bolted together to improve the sealing between the support plates 3 and the support frame 4.

[0030] In this embodiment, by stacking and coaxially arranging multiple support plates 3, the connecting rod 2 moves from the bottom of the support plates 3 to the middle of the multiple support plates 3 and is installed between the multiple support plates 3, so that the connecting rod 2 connects the multiple support plates 3 into a whole and creates a cavity between the multiple support plates 3. At the same time, the packing is placed between the multiple support plates 3 and placed on the support frame 4 by the connecting rod 2, so that the packing in the support plates 3 performs filtration inside the tower body 1. At the same time, the shape of the support plates 3 causes the packing to form pores after placement, reducing the surface tension of the liquid when passing through the packing, and increasing the liquid flow rate through gravity, thereby improving production efficiency.

[0031] Example 2

[0032] like Figure 3-4 As shown, the present invention proposes a desolvation tower. Compared with Embodiment 1, the difference between this embodiment and Embodiment 1 is that an annular plate 5 is provided at the top edge of the support plate 3, and the edge is slidably connected to the inner wall of the tower body 1. Moreover, the annular plate 5 on the lowest support plate 3 among the multiple support plates 3 is connected to the top of the support frame 4.

[0033] In an optional embodiment, multiple connecting plates 6 are provided between the multiple ring plates 5, and the multiple connecting plates 6 are arranged at equal angles around the center of the support plate 3.

[0034] In this embodiment, the ring plate 5 connects the support plate 3 to the support frame 4, and the cooperation between the connecting plate 6 and the ring plate 5 supports the edge of the support plate 3, so that the cavity size among the multiple support plates 3 is the same.

[0035] Example 3

[0036] like Figure 3-4 As shown, the present invention proposes a desolvation tower. Compared with Embodiment 1, the difference between this embodiment and Embodiment 1 is that the inner diameter of the support plate 3 gradually decreases from the top to the bottom of the tower body 1 along the height direction of the tower body 1, and the surface of the support plate 3 has multiple through holes.

[0037] In an optional embodiment, a sleeve 7 is provided in the middle of the support plate 3, which is sleeved on the outside of the connecting rod 2, and the height of the sleeve 7 is the same as the spacing between the multiple support plates 3.

[0038] It should be noted that the sleeve 7 has a threaded hole in the middle. When the connecting rod 2 and the sleeve 7 are installed together, the thread of the connecting rod 2 is arranged to match the threaded hole of the sleeve 7. Furthermore, multiple support plates 3 are connected by the connecting rod 2 to form a cavity, and the shape of the cavity is the same as that of the support plate 3.

[0039] In this embodiment, the spacing between multiple support plates 3 is controlled by the sleeve 7, so that the same amount of packing material is placed between the multiple support plates 3. The shape of the cavity between the multiple support plates 3 is the same as that of the support plates 3, so that the packing material forms a hole after placement, reducing the surface tension of the liquid when passing through the packing material, and increasing the liquid flow rate through the action of gravity, thereby improving production efficiency.

[0040] Example 4

[0041] like Figure 4 As shown, the present invention proposes a desolvation tower. Compared with Embodiment 1, the difference between this embodiment and Embodiment 1 is that the support frame 4 includes a connecting ring 41, a support rod 42, and a support plate 43.

[0042] The support plate 43 is installed on the inner side of the tower body 1;

[0043] The connecting ring 41 is sleeved on the outside of the connecting rod 2 and contacts the bottom end of the support plate 3;

[0044] There are multiple support rods 42, which are arranged at equal angles between the connecting ring 41 and the support plate 43 according to the center of the support plate 3, and their sides are in contact with the support plate 3.

[0045] In this embodiment, the support plate 43 supports the ring plate 5, allowing the support plate 43 to install the support plate 3 on the inner side of the tower body 1 via the ring plate 5. The support plate 3 is positioned below the center of the support plate 3 via a connecting ring 41. The support rod 42 is installed between the connecting ring 41 and the support plate 43, so that the surface of the support plate 3 contacts the support rod 42 after installation. The support rod 42 directly supports the support plate 3 through the cooperation of the connecting ring 41 and the support plate 43, thereby improving the stability of the support plate 3 installation.

[0046] In summary, in this utility model, by stacking and coaxially arranging multiple support plates 3, controlling the spacing between the multiple support plates 3 with sleeves 7, and cooperating with connecting plates 6 and ring plates 5 to support the edges of the support plates 3, the cavity sizes between the multiple support plates 3 are made the same. A connecting rod 2 moves from the bottom of the support plates 3 to the middle of the multiple sleeves 7 and is installed between the multiple sleeves 7, so that the connecting rod 2 and sleeves 7 cooperate to connect the multiple support plates 3 into a single unit. Simultaneously, the packing is placed separately between the multiple support plates 3, and the multiple support plates 3 are placed on the support plate 43 by the connecting rod 2. The support rod 42 directly supports the support plates 3 through the cooperation of connecting ring 41 and support plate 43, improving the stability of the support plate 3 installation. During the desolvation process, the packing in the support plates 3 performs filtration work inside the tower body 1. Furthermore, the shape of the support plates 3 causes the packing to form perforations after placement, reducing the surface tension of the liquid passing through the packing and increasing the liquid flow rate through gravity, thereby improving production efficiency.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
