Over time, they will accumulate and coke, blocking the pipe, causing the vacuum conditions to drop and affecting the normal operation of production. In severe cases, it may even lead to shutdown.

[0004] Therefore, there is a need for a structure to prevent the vapor phase pipe of the polymerization device from becoming clogged. Utility Model Content

[0033] like Figure 1-8As shown in this embodiment, a vapor phase pipe anti-clogging structure for a polymerization device includes a vapor phase pipe body 1, on which a steam pipe 2 is connected. The steam pipe 2 is connected to an EG steam system, where EG steam refers to ethylene glycol steam. During production operation, the EG steam is transported from the steam pipe 2 to the vapor phase pipe body 1 through the EG steam system. After entering the vapor phase pipe body 1, the EG steam carries away a large amount of heat, causing the oligomers adhering to the vapor phase pipe body 1 to cool down, solidify, and detach before being discharged, thus preventing clogging and improving the operational stability of the polymerization device.

[0034] It also includes a vibration mechanism 3, which is installed on the outer wall of the vapor phase tube body 1. During production operation, the vibration mechanism 3 generates vibration and transmits it to the oligomer inside the vapor phase tube body 1. The vibration facilitates the separation of the oligomer from the inner wall of the vapor phase tube, thereby improving the anti-clogging effect.

[0035] The vibration mechanism 3 includes a fixed ring 31 and a vibration unit 32. The fixed ring 31 is fixedly sleeved on the vapor phase tube body 1, and the vibration unit 32 is connected to the fixed ring 31.

[0036] The vibration unit 32 includes a movable rod 321, which is movably mounted on a fixed ring 31. A movable block 322 is fixedly mounted on one end of the movable rod 321. An electromagnet 323 is mounted on the side of the movable block 322 away from the movable rod 321. The electromagnet 323 is fixedly mounted on the vapor phase tube body 1. The electromagnet 323 and the movable block 322 are arranged opposite each other. The movable block 322 is made of iron. The movable block 322 is connected to the fixed ring 31 by a spring 324. A striking block 325 is fixedly mounted on the movable rod 321. The striking block 325 is located on the side of the fixed ring 31 away from the movable block 322.

[0037] Multiple fixed rings 31 are provided, and the multiple fixed rings 31 are arranged at intervals along the length direction of the vapor phase pipe body 1. Multiple striking blocks 325 are provided on the moving rod 321, and the multiple striking blocks 325 correspond one-to-one with the multiple fixed rings 31.

[0038] Multiple vibration units 32 are provided, and the multiple vibration units 32 are evenly distributed circumferentially around the vapor phase tube as the center.

[0039] Multiple moving blocks 322 surround each other to form a ring;

[0040] During production, electromagnet 323 is intermittently energized. When electromagnet 323 is energized, it attracts the moving block 322, causing the moving block 322 to move closer to the electromagnet 323. The movement of the moving block 322 drives the moving rod 321 and the striking block 325 to move synchronously, and causes the spring 324 to deform. When the striking block 325 comes into contact with the fixed ring 31, the fixed ring 31 vibrates, and the vibration is transmitted to the oligomer in the vapor phase pipe body 1. When electromagnet 323 is de-energized, the elastic action of the spring 324 causes the moving block 322 to move in the opposite direction to achieve reset, that is, to reset the moving rod 321 and the striking block 325. This process is repeated.

[0041] The vibration mechanism 3 also includes a cooling unit 33, which is mounted on a fixed ring 31. The fixed ring 31 is made of heat-insulating material. The cooling unit 33 is connected to a moving block 322. The movement of the moving block 322 causes the cooling unit 33 to blow air into the vapor phase pipe.

[0042] Multiple cooling units 33 are provided, and the multiple cooling units 33 are evenly distributed circumferentially around the vapor phase pipe as the center. The multiple cooling units 33 and multiple vibration units 32 are arranged alternately.

[0043] The cooling unit 33 includes a fixed tube 331, which is located on the side of the moving block 322 near the fixed ring 31. The fixed tube 331 is parallel to the moving rod 321. The end of the fixed tube 331 away from the moving block 322 is sealed. A plunger 332 is inserted into the other end of the fixed tube 331. The plunger 332 is slidably and sealingly connected to the fixed tube 331. The plunger 332 is fixedly mounted on the moving block 322. A vent 333 is provided on the side of the fixed tube 331 near the vapor phase tube body 1. Multiple vents 333 are provided and distributed along the length of the fixed tube 331.

[0044] When the moving block 322 moves toward the electromagnet 323, it drives the plunger 332 to move synchronously, which reduces the depth of the piston inserted into the fixed tube 331, so that the air outside the fixed tube 331 enters the fixed tube 331 through the air hole 333. When the moving block 322 moves in the opposite direction, it drives the plunger 332 to move in the opposite direction, so that the air in the fixed tube 331 acts on the vapor phase tube body 1 through the air hole 333, which increases the air flow rate outside the vapor phase tube body 1, improves the heat dissipation effect of the vapor phase tube, and thus improves the cooling and solidification efficiency of the oligomer.

[0045] In summary, during production operation, by introducing EG vapor into the vapor phase tube body 1, the oligomers adhering to the vapor phase tube body 1 are cooled, solidified, detached, and discharged, thus preventing blockage and improving the operational stability of the polymerization unit. Furthermore, vibration facilitates the separation of oligomers from the vapor phase tube body 1, enhancing the anti-blockage effect. Secondly, by applying air to the vapor phase tube body 1, the external air velocity of the vapor phase tube body 1 is increased, improving the heat dissipation effect of the vapor phase tube and thereby increasing the cooling and solidification efficiency of the oligomers.
