Description

Technical Field

[0001] This utility model relates to the field of fractionation tower technology, specifically to an environmentally friendly reforming oil fractionation tower with a gas filtration structure. Background Technology

[0002] Fractional distillation is a method for separating mixtures with different boiling points. It involves heating a mixture and then cooling it to separate the components into relatively pure single substances based on their different boiling points. No new substances are formed during this process; only the original substances are separated. It is a physical change, and fractionation columns are separation towers built based on this principle.

[0003] A search revealed Chinese Patent Publication No. CN211227026U, which discloses an aromatic reforming oil fractionation tower for printing oil formulation. The tower includes a fractionation tower and a heater located on one side of the tower. A closed-end separation cylinder is installed on the top of the heater, and an inlet pipe is fixedly connected to the side wall of the heater away from the fractionation tower. A support cylinder and a separation filter screen are fixedly connected vertically from top to bottom to the inner wall of the separation cylinder. This invention separates impurities from the gas using the separation filter screen. Simultaneously, multiple taps are applied to the separation filter screen using a tapping block to prevent impurities from accumulating on it and thus preventing impurities from entering the fractionation tower.

[0004] The aforementioned device has certain drawbacks in practical use. Using a striking block to tap the separator screen causes impurities to fall into the heater, affecting not only its heating efficiency but also the quality of the product fractionation. Over time, this can lead to equipment blockage, hindering fractionation processing, disrupting normal production, and causing significant losses for the company. Utility Model Content

[0024] The following will be combined with the appendix Figures 1 to 5 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1

[0026] Please see Figures 1-6 An environmentally friendly reforming oil fractionation tower with a gas filtration structure includes a bottom plate 1, a fractionation tower body 2, and a heater 4. The heater 4 and the fractionation tower body 2 are sequentially arranged on the bottom plate 1. One end of the heater 4 is provided with a liquid inlet pipe 3. The heater 4 is provided with a filtration mechanism. The filtration mechanism is provided with a reciprocating mechanism. The filtration mechanism is connected to the fractionation tower body 2 through a connecting pipe 8. A protective sleeve 23 is provided on the outside of the connecting pipe 8. A heat insulation layer 24 is provided between the protective sleeve 23 and the connecting pipe 8. The bottom plate 1 is connected to the bottom end of the filter box 7 through a support column 5.

[0027] Through the cooperation of the above mechanisms, the filter screen 14 can be vibrated regularly to clean the attached impurities and ensure the filtration effect of the filter screen 14. At the same time, it can also prevent impurities from falling into the heater 4, ensuring the normal use of the equipment. It not only ensures the effect and quality of fractionation, but also avoids clogging and ensures the production use of the enterprise.

[0028] Example 2

[0029] Please see Figure 1 , Figure 2 , Figure 5 The filtration mechanism includes a filter box 7 mounted on the heater 4. The filter box 7 is connected to the heater 4 via an air outlet pipe 6. Inside the filter box 7, a filter screen 14 is mounted via a reciprocating mechanism. The filter screen 14 is connected to the filter box 7 via a drive mechanism. The filtration mechanism also includes a conical guide column 9 mounted below the filter screen 14. The conical guide column 9 has through holes 22 equidistantly spaced on its circumferential side, and the through holes 22 are connected to the air outlet pipe 6.

[0030] During use, the product heated and vaporized by heater 4 enters the conical guide column 9 through the gas outlet pipe 6, and then enters the filter screen 14 through the through hole 22 for filtration. This filters and adsorbs impurities in the gas, preventing them from entering the fractionation tower body 2 and ensuring the quality of product fractionation. At the same time, when cleaning the filter screen 14, the conical guide column 9 facilitates the removal of impurities from the bottom of the filter box 7 for unified treatment, allowing for regular cleaning of the filter box 7 and preventing clogging.

[0031] Example 3

[0032] Please see Figures 1-4The reciprocating mechanism includes a fixed plate 11 symmetrically arranged inside the filter box 7. Guide posts 16 are equidistantly arranged on the fixed plate 11, and the fixed plate 11 is connected to the filter screen 14 through the guide posts 16. A limit plate 12 is threadedly connected to the guide posts 16, and a spring 13 is sleeved on the outside of the guide posts 16. The driving mechanism includes a mounting plate 17 arranged at one end of the filter box 7. A motor 10 is arranged on the mounting plate 17. The output end of the motor 10 passes through the filter box 7 and extends into the interior to provide a crankshaft 15. A collar 18 is equidistantly arranged on the crankshaft 15. A connecting rod 20 is provided below the collar 18. One end of the connecting rod 20 is connected to the collar 18 through a rotating block 19, and the other end is threadedly connected to a mounting seat 21 through the rotating block 19. The mounting seat 21 is connected to the filter screen 14.

[0033] The filter screen 14 can be vibrated by the cooperation of the drive mechanism and the reciprocating mechanism, which can shake off the impurities attached to it. The filter screen 14 can be cleaned regularly to ensure its filtration effect. The reciprocating mechanism and the drive mechanism are connected and fixed to the filter screen 14 by threads, which can facilitate the disassembly of the filter screen 14. After long-term use, a thorough cleaning can be performed to remove the remaining impurities shaken off, ensuring the filtration effect of the filter screen 14. At the same time, it can be easily replaced when it is damaged, ensuring the filtration effect of the filtration mechanism and thus ensuring the fractionation quality of the product.

[0034] Working principle: The product to be fractionated enters the heater 4 through the inlet pipe 3, where it is heated to generate gas. This gas then enters the conical guide column 9 through the outlet pipe 6, passes through the through-hole 22, and enters the filter screen 14 for adsorption and filtration. Finally, it enters the fractionation tower body 2 through the connecting pipe 8 for further fractionation. The protective sleeve 23 on the outside of the connecting pipe 8 protects it from damage, and the heat insulation layer 24 reduces heat exchange with the outside environment, preventing liquefaction inside the connecting pipe 8 and thus affecting the quality of fractionation. When the filter screen 14 needs to be cleaned by vibration, the motor 10 rotates, causing the crankshaft 15 to rotate. At this time, under the combined action of the connecting rod 20 under the collar 18 and the rotating block 19, the filter screen 14 moves up and down reciprocatingly. Simultaneously, the filter screen 14 slides on the guide column 16 and, under the action of the spring 13, can move back and forth. The reciprocating motion shakes off the impurities attached to the filter. Simultaneously, the conical guide column 9 facilitates the impurities falling to the bottom of the filter box 7 for unified processing. This allows for regular cleaning of the filter box 7, preventing blockages and ensuring the impurities don't fall back into the heater 4 through the outlet pipe 6. This guarantees normal equipment operation, ensuring both fractionation effect and quality, while also preventing blockages and ensuring normal production. The reciprocating mechanism and drive mechanism are connected to the filter screen 14 via threads, allowing for easy disassembly and thorough cleaning over extended periods to remove residual impurities. This ensures the filtration effect of the filter screen 14 and facilitates easy replacement when damaged, maintaining the filtration efficiency and ultimately guaranteeing the fractionation quality of the product.
