Description

Technical Field

[0001] This utility model relates to the field of light oil recovery technology, specifically to a recovery and fractionation tower for light oil. Background Technology

[0002] A search revealed a patent publication with publication number CN221692828U, which describes a light oil recovery fractionation tower. Specifically, the tower includes: "A light oil recovery fractionation tower comprising a tower body and a feed pipe installed on one side of the bottom of the tower body, with a support foot fixedly installed at the bottom of the tower body; fractionation components, comprising several groups, which are equally spaced within the tower body; each fractionation component includes an installation frame installed within the tower body, and several reflux grooves installed on the installation frame; a gas lift cap is installed above two adjacent reflux grooves; the installation frame has a liquid collection chamber communicating with the reflux grooves; an oil drain pipe is installed on the installation frame, one end of which communicates with the liquid collection chamber, and the other end of which passes through the tower body and communicates with a re-distillation mechanism. The light oil recovery fractionation tower provided by this utility model has the advantage of high fractionation quality."

[0003] Through the search of the above schemes, we found that the fractionation tower still has certain defects in use. The mixed oil is introduced into the tower body through the feed pipe and is heated and distilled. The mixed oil is distilled through several fractionation components arranged in sequence in the tower body. Due to the limited space at the bottom wall of the tower body, that is, only one liquid surface can be formed. The mixed oil can only achieve vapor rise from above one liquid surface, which results in low vapor formation efficiency of the mixed oil and makes it difficult to achieve efficient recovery of light oil.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 A fractionation tower for recovering light oil includes a tower body 1. A re-distillation mechanism 4 is provided on the outer wall of the tower body 1. A fractionation assembly is provided inside the tower body 1 and at the position corresponding to the re-distillation mechanism 4. A heating tank 3 is provided on the inner bottom wall of the tower body 1. A partition plate 301 and a partition plate 302 are fixed inside the heating tank 3 from top to bottom. The interior of the heating tank 3 is divided into a distillation chamber 7, a distillation chamber 8, and a distillation chamber 9 by the partition plate 301 and the partition plate 302. A steam outlet pipe 5 is fixed at the center of the top of the partition plate 301. A steam outlet pipe 6 is connected to the center of the top of the partition plate 302. A feed pipe 2 is connected to one side of the tower body 1. The feed pipe 2 is connected to the mixed oil processed in the previous process. The outlet end of the feed pipe 2 is fixedly inserted into the interior of the tower body 1 and placed above the heating tank 3.

[0022] Please see Figure 2 and Figure 3 In this embodiment, steam outlet pipe 5 is used to connect distillation chamber 7 and distillation chamber 8, and steam outlet pipe 6 is used to connect distillation chamber 8 and distillation chamber 3 and 9. The inner diameter of steam outlet pipe 5 is larger than the outer diameter of steam outlet pipe 6.

[0023] Specifically, steam outlet pipe 5 and steam outlet pipe 6 facilitate the upward discharge of steam. On the other hand, when adding mixed oil, after the liquid level inside distillation chamber 7 is parallel to steam outlet pipe 5, the continuously discharged mixed oil will flow down along the inner wall of steam outlet pipe 5. Since the inner diameter of steam outlet pipe 5 is larger than the outer diameter of steam outlet pipe 6, the mixed oil flowing down from the inner wall of steam outlet pipe 5 will first fall into distillation chamber 8. After the liquid level inside distillation chamber 8 is parallel to steam outlet pipe 6, the continuously discharged mixed oil will enter distillation chamber 9 through steam outlet pipe 6.

[0024] Please see Figure 2 , Figure 3 and Figure 4 In this embodiment, the top and bottom surfaces of partition plate 1 301 and partition plate 2 302 are designed as inclined structures, the inner bottom wall of heating tank 3 is designed as an inclined structure, and the bottom of distillation chamber 1 7, distillation chamber 2 8 and distillation chamber 3 9 are all connected to discharge pipes 12, and the other end of multiple discharge pipes 12 are fixedly inserted through tower body 1 and equipped with valves 13.

[0025] Specifically, the top surfaces of partition plate 1 (301) and partition plate 2 (302) are designed with an inclined structure, and the inner bottom wall of heating tank 3 is designed with an inclined structure. This facilitates the flow of the mixed oil and allows for the discharge of residual material through discharge pipe 12 by opening valve 13. The inclined bottom surfaces of partition plate 1 (301) and partition plate 2 (302) are designed to guide and gather the rising steam, facilitating its rapid discharge from the corresponding compartments. Ultimately, the steam generated on the surface of the mixed oil in distillation compartment 1 (7) gathers and moves upward. That is, the steam generated on the surface of the mixed oil in distillation compartment 1 (7) rises directly, the steam generated on the surface of the mixed oil in distillation compartment 2 (8) is discharged from steam outlet pipe 1 (5), and the steam generated on the surface of the mixed oil in distillation compartment 3 (9) is discharged from steam outlet pipe 2 (6) and then from steam outlet pipe 1 (5).

[0026] Please see Figure 2 and Figure 3 In this embodiment, electric heating plates 10 are installed in the frame of the heating tank 3 at positions corresponding to the first distillation chamber 7, the second distillation chamber 8, and the third distillation chamber 9, respectively. The power transmission ends of the multiple electric heating plates 10 are connected to wires 2, and one end of each wire 2 is connected to wire 11, which is connected to the mains power.

[0027] Specifically, the electric heating plates 10 at different locations can heat the first distillation chamber 7, the second distillation chamber 8, and the third distillation chamber 9 respectively, so that the mixed oil inside the first distillation chamber 7, the second distillation chamber 8, and the third distillation chamber 9 can be heated separately and achieve the effect of heating and distillation.

[0028] Please see Figure 2 In this embodiment, the inner top wall edge of the heating barrel 3 is designed to be inclined, and the outer wall of the heating barrel 3 is welded to the inner wall of the tower body 1.

[0029] Specifically, by designing an inclined edge at the top wall of the heating tank 3, liquid that may condense on the inner wall of the tower body 1 can easily flow back into the heating tank 3 and into the distillation chamber 7. The welding of the outer wall of the heating tank 3 to the inner wall of the tower body 1 ensures the stability of the heating tank 3.

[0030] Please see Figure 2 and Figure 3In this embodiment, the height of steam outlet pipe 5 is lower than the height of distillation chamber 7, and the height of steam outlet pipe 6 is lower than the height of distillation chamber 8.

[0031] Specifically, through the above design, the mixed oil inside distillation chamber 1 7 can be conveniently discharged into distillation chamber 2 8 after reaching a suitable liquid level, and the mixed oil inside distillation chamber 2 8 can be conveniently discharged into distillation chamber 3 9 after reaching a suitable liquid level, thereby facilitating the formation of multiple liquid levels.

[0032] In use: The mixed oil is fed into the tower body 1 through the feed pipe 2 and first falls onto the partition plate 301 and gradually fills the distillation chamber 7. When the liquid level of the mixed oil is parallel to the steam outlet pipe 5, the continuously discharged mixed oil enters the steam outlet pipe 5 and falls onto the partition plate 302, gradually filling the distillation chamber 8. When the liquid level of the mixed oil is parallel to the steam outlet pipe 6, the continuously discharged mixed oil enters the steam outlet pipe 6 and falls into the distillation chamber 9 of the heating tank 3, so that the mixed oil is present in the distillation chambers 7, 8, and 9.

[0033] The electric heating plate 10 is activated, which heats and distills the mixed oil in distillation chamber 7, distillation chamber 8 and distillation chamber 9 respectively. The generated steam rises and is discharged through steam outlet pipe 6 and steam outlet pipe 5. The rising steam works in conjunction with the fractionation components and re-distillation mechanism 4 on the tower body 1 to produce light oil.

[0034] It should be noted that the tower body 1, the fractionation component, and the re-distillation mechanism 4 are all common knowledge in the field and have been described in detail in the published patent with publication number CN221692828U. Their working principles are already known technologies, so they will not be described in detail in this application.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
