Description

Technical Field

[0001] This utility model relates to the technical field of aromatic hydrocarbon extraction equipment, and in particular to a purification device for the extraction and deacidification of aromatic hydrocarbons with sulfolane. Background Technology

[0002] Aromatic extraction, also known as aromatic extraction, is a liquid-liquid extraction process that uses an extractant to separate aromatics from a mixture of hydrocarbons. In existing technologies, most of these processes use reformed oil as raw material and employ aromatic extraction towers to extract aromatics from it. However, due to the high concentration of reformed oil, local blockages can easily occur during its transport within the pipeline.

[0003] Existing aromatic extraction methods often involve high concentrations of reformed oil, which can lead to localized blockages during pipeline transport. Therefore, a purification device for aromatic extraction and sulfolane deacidification is needed. Utility Model Content

[0004] The purpose of this invention is to provide a purification device for the extraction and deacidification of aromatic hydrocarbons with sulfolane, which solves the problem of easy local blockage in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a purification device for aromatic hydrocarbon extraction and deacidification of sulfolane, comprising an extraction tower, an oil inlet pipe integrally provided on one side of the extraction tower, a transfer pipe installed at the end of the oil inlet pipe, a flange integrally provided at the rear end of the transfer pipe, a sealing ring installed inside the transfer pipe, a fixing frame welded to the middle of the transfer pipe, a rotating rod rotatably installed in the middle of the fixing frame, a transmission mechanism provided at the end of the rotating rod, a crushing mechanism installed outside the rotating rod, a cleaning ring provided at the tail end of the rotating rod, an external interface provided on the front section of the transfer pipe, and an internal interface provided inside the front section of the transfer pipe.

[0006] Preferably, the adapter pipe forms a detachable structure with the oil inlet pipe via a flange, and the adapter pipe forms a sealed structure with the oil inlet pipe via a sealing ring.

[0007] Preferably, the transmission mechanism includes a first bevel gear, a second bevel gear meshing with the outer side of the first bevel gear, and the top of the second bevel gear being connected to the output end of a motor.

[0008] Preferably, the rotating rod forms a transmission structure between the first bevel gear and the second bevel gear, and the rotating rod forms a rotation structure between the fixed frame and the extraction tower.

[0009] Preferably, the crushing mechanism includes a positioning ring, a first blade is mounted on the outer front side of the positioning ring, and a second blade is mounted on the outer rear side of the positioning ring.

[0010] Preferably, the positioning ring is welded to the rotating rod, and the positioning ring forms a rotating structure with the oil inlet pipe through the rotating rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting up a transmission mechanism, the transfer pipe is connected to the oil inlet pipe through a flange. The built-in sealing ring can effectively seal the connection, ensuring that the internal crude oil will not leak. After installation, the entire rotating rod and cleaning ring can penetrate into the interior of the oil inlet pipe, making it convenient to control the rotation of the rotating rod at a uniform speed through the transmission mechanism. When the rotating rod drives the external crushing mechanism to rotate, it can ensure the flow of the internal crude oil during transportation, reducing blockage when the flow rate is slow and reducing sludge accumulation. At the same time, it can break up larger crude oil blocks, ensuring that the inside of the pipeline is unobstructed. Multiple sets of crushing mechanisms and staggered first and second blades ensure better agitation of the crude oil on the back during rotation, and also facilitate the crushing of internal lumps, reducing internal sludge accumulation.

[0013] 2. By setting a cleaning ring, the rear cleaning ring can scrape the inner wall of the oil inlet pipe during entry and exit. This not only provides support for the overall use of the rotating rod, but also facilitates the cleaning of the inner wall of the pipe. It is stable and flexible in use. At the same time, the front end of the adapter pipe is equipped with an external interface and an internal interface, which can be selected according to the specifications of the subsequent adapter pipe to ensure better adaptation to different connection needs and facilitate the adapter operation.

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.

[0020] Example 1

[0021] like Figure 1-4 As shown in the figure, a purification device for aromatic hydrocarbon extraction and deacidification of sulfolane includes an extraction tower 1. An oil inlet pipe 2 is integrally provided on one side of the extraction tower 1. A transfer pipe 3 is installed at the end of the oil inlet pipe 2. A flange 4 is integrally provided at the rear end of the transfer pipe 3. A sealing ring 5 is installed inside the transfer pipe 3. A fixing frame 6 is welded to the middle of the transfer pipe 3. A rotating rod 7 is rotatably installed in the middle of the fixing frame 6. A transmission mechanism 8 is provided at the end of the rotating rod 7. A crushing mechanism 9 is installed on the outside of the rotating rod 7. A cleaning ring 10 is provided at the tail end of the rotating rod 7. An external interface 11 is provided on the front section of the transfer pipe 3. An internal interface 12 is provided on the front section of the transfer pipe 3.

[0022] The adapter pipe 3 forms a detachable structure with the oil inlet pipe 2 via the flange 4, and the adapter pipe 3 forms a sealed structure with the oil inlet pipe 2 via the sealing ring 5. The adapter pipe 3 is connected and assembled with the oil inlet pipe 2 via the flange 4. The built-in sealing ring 5 can effectively seal the connection and ensure that the crude oil inside will not leak.

[0023] The transmission mechanism 8 includes a first bevel gear 801, a second bevel gear 802 meshing with the outer side of the first bevel gear 801, and the output end of the motor 803 connected to the top of the second bevel gear 802.

[0024] The rotating rod 7 forms a transmission structure between the first bevel gear 801 and the second bevel gear 802, and the rotating rod 7 forms a rotation structure between the fixed frame 6 and the extraction tower 1. When the rotating rod 7 drives the externally installed crushing mechanism 9 to rotate, it can ensure the flow of the internal crude oil during transportation, reduce the occurrence of blockage when the flow rate is slow, and reduce siltation.

[0025] The crushing mechanism 9 includes a positioning ring 901, a first blade 902 is mounted on the outer front side of the positioning ring 901, and a second blade 903 is mounted on the outer rear side of the positioning ring 901.

[0026] The positioning ring 901 is welded to the rotating rod 7, and the positioning ring 901 forms a rotating structure with the oil inlet pipe 2 through the rotating rod 7. The multiple sets of crushing mechanisms 9 and the staggered first blade 902 and second blade 903 ensure better agitation of the crude oil on the back when rotating, and also facilitate the crushing of internal lumps and reduce internal blockage.

[0027] Working principle: First, the transfer pipe 3 is connected to the oil inlet pipe 2 via the flange 4. The built-in sealing ring 5 can effectively seal the connection, ensuring that the crude oil inside will not leak. After installation, the entire rotating rod 7 and cleaning ring 10 can penetrate into the interior of the oil inlet pipe 2, making it easy to control the rotation of the rotating rod 7 at a uniform speed through the transmission mechanism 8. When the rotating rod 7 drives the externally installed crushing mechanism 9 to rotate, it can ensure the flow of the crude oil inside during transportation, reducing blockage when the flow rate is slow and reducing sludge accumulation. At the same time, it can break up larger crude oil blocks, ensuring that the inside of the pipeline is unobstructed. The multiple sets of crushing mechanisms 9 and the staggered first blade 902 and second blade 903 ensure better agitation of the crude oil on the back during rotation, and also facilitate the crushing of internal lumps, reducing internal sludge accumulation.

[0028] Next, the cleaning ring 10 on the rear side can scrape the inner wall of the oil inlet pipe 2 during entry and exit. It not only supports the overall use of the rotating rod 7, but also facilitates the cleaning of the inner wall of the pipe. It is stable and flexible in use. At the same time, the front end of the adapter pipe 3 is provided with an external interface 11 and an internal interface 12, which can be selected according to the specifications of the subsequent adapter pipe to ensure better adaptation to different connection needs and facilitate the adapter operation.
