Description

Technical Field

[0001] This utility model relates to the field of diffuser technology, and in particular to an advanced inlet diffuser for a hydrogenation reactor. Background Technology

[0002] Hydrogenation reactors are core equipment in petroleum refining and chemical synthesis. They achieve process goals such as desulfurization, denitrification, and olefin saturation by catalytically reacting hydrogen with feedstock under high temperature and pressure conditions. Their operating environment is typically high pressure and high temperature, and they must withstand corrosive media such as hydrogen sulfide. The diffuser, as the first internal component of the reactor, is directly installed below the reactor inlet flange to receive the high-speed incoming oil and gas medium. Its conical structure is aligned with the center of the feed pipe, ensuring that the fluid vertically impacts the baffles for diffusion.

[0003] After prolonged use, existing diffusers accumulate a large amount of debris on their surface. At this point, staff typically clean them using high-pressure water jets or chemicals. However, this process can leave some blind spots in the cleaning process, which can negatively impact the subsequent use of the diffuser.

[0004] Therefore, those skilled in the art have provided advanced inlet diffusers for hydrogenation reactors to address the problems raised in the background section above. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution for an advanced inlet diffuser for a hydrogenation reactor: It includes a diffuser body 1, inside which a first baffle 2 and a second baffle 3 are installed. Both the first baffle 2 and the second baffle 3 have flow holes 4. A cleaning mechanism is provided inside the diffuser body 1. The cleaning mechanism includes a base plate 5 located below the first baffle 2. A base 6 is rotatably connected to the upper end of the base plate 5. A connecting column 7 is provided on the base 6, and the two are connected by a connecting mechanism. An arc-shaped plate 8 is embedded in the connecting column 7, and the two... The components are connected by a movable mechanism. Multiple bristles 9 are fixedly connected to the arc plate 8. The diameter of the connecting post 7 is slightly smaller than the diameter of the flow hole 4. A slider is fixedly connected to the outer wall of the connecting post 7. A spiral groove adapted to the slider is opened on the inner wall of the flow hole 4. A cleaning mechanism is provided below the first baffle 2 and the second baffle 3. The number of flow holes 4 on the second baffle 3 is more than the number of flow holes 4 on the first baffle 2. The initial position of the connecting post 7 is located directly below the two flow holes 4 and will not obstruct the flow holes 4.

[0025] The cleaning mechanism also includes a connecting rod 13 that runs through and is fixedly connected to the first baffle 2. The lower end of the connecting rod 13 is fixedly connected to a drive motor 12. The drive motor 12 is connected to the first baffle 2 through a telescopic connector (not shown in the figure). When the drive motor 12 is working, it can drive the base plate 5 to rotate through the connecting rod 13. The rotation angle can be set in advance.

[0026] The cleaning mechanism also includes a groove 10 at the center of the lower end of the base plate 5. An electric telescopic rod 11 is rotatably connected inside the groove 10. The electric telescopic rod 11 is fixedly connected to the connecting rod 13. The electric telescopic rod 11 can drive the base plate 5 to move up and down. The telescopic connecting part allows the drive motor 12 to move with the base plate 5 without obstructing the movement of the electric telescopic rod 11.

[0027] The movable mechanism includes a spring column 17 fixedly connected inside the arc plate 8. A movable block 18 is fixedly connected to the movable end of the spring column 17. An embedding groove 19 adapted to the movable block 18 is provided on the connecting column 7. A moving block 16 is fixedly connected to the movable block 18. One end of the moving block 16 extends through to the outside of the arc plate 8. Under the limitation of the spring column 17, the movable block 18 can be inserted into the interior of the embedding groove 19, thereby completing the fixation of the arc plate 8 based on the connecting column 7.

[0028] The arc plate 8 has a moving groove for the moving block 16 to move. One end of the arc plate 8 is fixedly connected to a fixing block 20, and the connecting column 7 has a fixing groove 21 that is compatible with the fixing block 20.

[0029] The connecting mechanism includes a spiral column 14 fixedly connected to the base 6. A spiral groove 15 is provided at the lower end of the connecting column 7. The spiral column 14 and the spiral groove 15 are spirally connected. The connecting column 7 can be rotated based on the base 6 to realize the connection and separation of the spiral column 14 and the spiral groove 15, which is convenient for disassembly and replacement.

[0030] Both the electric telescopic pole 11 and the drive motor 12 are equipped with protective covers, which prevent external substances from affecting them and provide excellent protection.

[0031] The working principle of this utility model is as follows: When it is necessary to clean the first baffle 2 and the second baffle 3 inside the diffuser body 1, the drive motor 12 first drives the base plate 5 to rotate through the connecting rod 13, thereby moving the connecting column 7 directly below the flow hole 4. Then the electric telescopic rod 11 is retracted, and the base plate 5 is moved upward through the connecting rod 13, thereby moving the connecting column 7 into the flow hole 4. At this time, under the action of the slider and the spiral groove, the connecting column 7 and the base 6 rotate based on the base plate 5. At this time, the bristles 9 can brush the flow hole 4, and with the help of high-pressure water washing, a thorough cleaning is achieved. When the bristles 9 are worn, it is only necessary to move the movable block 18 through the moving block 16, so that the movable block 18 moves from the inside of the embedded groove 19, and the arc plate 8 with the bristles 9 can be disassembled and replaced, which is very convenient. When it is necessary to replace the worn connecting column 7, it is only necessary to rotate the connecting column 7 based on the base 6, so that the spiral column 14 is separated from the spiral groove 15, which is convenient for disassembly and replacement.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
