Description

Technical Field

[0001] The invention relates to the technical field of polypropylene polymerization production, in particular to a polypropylene polymerization reaction device and a method. Background Art

[0002] The general process of polypropylene polymerization consists of three parts: raw material preparation, polymerization reaction and post-processing. In the polymerization reaction step, gaseous propylene needs to be converted into liquid. During the liquefaction process, the kinetic energy of propylene molecules decreases and the distance between molecules shortens, allowing them to gather together to form a liquid, which is then formed into a polymer and finally sent to the post-processing part.

[0003] First, gaseous propylene is compressed to a high pressure state. Usually, when the pressure reaches 3.7 MPa, propylene can be converted from gas to liquid. Liquid propylene undergoes polymerization reaction under the action of a catalyst to form polypropylene.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The invention provides a polypropylene polymerization reaction device and method. Through the setting of a reaction mechanism, gaseous polypropylene and an added catalyst are centrifugally fused, and the fusion is intermittently centrifuged. At this time, the centrifugal component is continuously deformed and rotated up and down inside a cavity due to the control of the rotation rate. After the initial fusion of the polypropylene, it not only has a certain fluidity, but also is in a relatively viscous state. At this time, the polypropylene is lifted and pushed, and the liquid propylene and the catalyst are separated and processed and fall into the bottom of the cavity. The additive and the gaseous polypropylene are still centrifugally fused in the reaction tank. When the temperature in the cavity is low, hot air is added into the reaction tank through the top. At this time, after the hot air is partially blocked by the reaction mechanism, it is disturbed and processed into turbulence and distributed in the tank, thereby reducing the operation steps and improving the work efficiency.

[0017] The present invention provides a polypropylene polymerization reaction device and method. Through the arrangement of a reaction mechanism and a treatment mechanism, when in use, excess propylene gas can be separated and treated from liquid propylene, so as to facilitate recycling and polymerization reaction. Moreover, due to the viscosity of liquid propylene, the coolant of the device and other additives will be triggered to drain. When the flow rate is too slow, the amount of added becomes less. When a large amount of polypropylene is introduced, the amount of added will be increased so that it can enter the next process together with the polypropylene. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0034] Combination Figure 1-Figure 13 A polypropylene polymerization reaction device and method, a polypropylene polymerization reaction device, comprising a reaction tank 1, a processing mechanism 2 is arranged on the surface of the reaction tank 1, a reaction mechanism 3 is fixedly installed inside the reaction tank 1, and a driving motor 4 is fixedly connected to the bottom surface of the reaction tank 1.

[0035] See also Figure 2-Figure 13The processing mechanism 2 includes a first main pipeline 21 arranged on the surface of the reaction tank 1, a second sub-pipe 22 is arranged inside the first main pipeline 21, a guide pipe 23 is fixedly connected inside the second sub-pipe 22, a liquid outlet groove is provided on the side of the guide pipe 23 close to the first main pipeline 21, a hollow column 24 is fixedly connected to the end of the guide pipe 23, a movable block 25 is slidably connected to the inside of the hollow column 24 through a first spring, a closed block 26 is fixedly connected to the other end of the movable block 25, a bending part of the surface of the closed block 26 is slidably connected to the inside of the liquid outlet groove, a separation block 27 is arranged on the side of the surface of the closed block 26 away from the movable block 25, a plurality of guide holes 28 are opened inside the separation block 27, and the guide holes 28 are tapered, a storage chamber 29 is also fixedly installed on the side of the surface of the first main pipeline 21 close to the guide pipe 23, and an air guide hole is opened on the side of the second sub-pipe 22 close to the storage chamber 29.

[0036] When the polypropylene mixture passes through the second sub-pipeline 22, the gaseous propylene is drained out through the guide hole 28 and enters the cavity formed by the second sub-pipeline 22 and the hollow column 24. The remaining polypropylene flows inside the second sub-pipeline 22. At this time, the polypropylene will drive the separation block 27 to move forward. When the polypropylene flow rate is too large, the separation block 27 will be tilted to the inside of the second sub-pipeline 22 accordingly. The separation block 27 is smaller than the cavity radius of the second sub-pipeline 22 and leaves a certain tilting space. When the separation block 27 is pushed forward, it drives the sealing block 26 to move forward, opens part of the liquid outlet trough, and releases the polypropylene. When the polypropylene does not flow inside the second sub-pipeline 22, the first spring inside the hollow column 24 resets the movable block 25 and the sealing block 26, so that the inside of the guide tube 23 cavity is sealed again.

[0037] The reaction mechanism 3 includes a partition plate 31 fixedly installed inside the reaction tank 1, and two groups of pushing components 32 are arranged on the top surface of the partition plate 31, and the bottom surface of the pushing component 32 is rotatably connected with the first operating tooth 33. A centrifugal component 34 is also arranged in the middle of the top surface of the partition plate 31, and an intermittent wheel 35 is arranged on the bottom surface of the partition plate 31, and the top surface of the intermittent wheel 35 is fixedly connected with the centrifugal component 34. The surface of the first operating tooth 33 is meshed with the second operating tooth 36, and the second operating tooth 36 is arranged on the bottom surface of the partition plate 31. The bottom surface of the second operating tooth 36 is rotatably connected with the control rod 37, and the bottom surface of the second operating tooth 36 is located at the center of the second operating tooth 36 and is fixedly connected to the output end of the drive motor 4. The first operating tooth 33, the second operating tooth 36 and the intermittent wheel 35 are all arranged on the bottom surface of the partition plate 31.

[0038] A limiting slot 321 is provided inside the pushing assembly 32, and a travel rod 322 is rotatably connected to the bottom surface of the pushing assembly 32. A travel block 323 is provided on the surface of the travel rod 322, and the travel block 323 slides inside the limiting slot 321. A travel tooth 324 is rotatably connected to the surface of the travel block 323, and a lifting plate 325 is provided on the surface of the travel tooth 324. A push plate 326 is slidably connected to the inside of the lifting plate 325 via a second spring. The lifting plate 325 and the push plate 326 are in the shape of oblique curved blocks and have a small opening facing the first main pipe 21. A guide tooth 327 is also provided on the surface of the limiting slot 321, and the bottom end of the travel rod 322 is fixedly connected to the first running tooth 33.

[0039] When the device is in operation, the push plate 326 connected by the spring inside the lifting plate 325 will be pushed toward the inner wall of the reaction tank 1. When the lifting plate 325 is in operation, the arc angle opening on the lifting plate 325 will drain the solution with lower density downward. When the lifting plate 325 is lifted to a certain height, the travel tooth 324 will tilt the lifting plate 325 under the control of the guide tooth 327, so that the push plate 326 connected to the lifting plate 325 can pass the polypropylene liquid into the second auxiliary pipeline 22. The first main pipeline 21 does not intersect with the interior of the reaction tank 1, and the second auxiliary pipeline 22 and the interior of the reaction tank 1 intersect with each other.

[0040] The surface of the centrifugal component 34 is slidably connected to a first moving block 341, and a second moving block 342 is slidably connected to the side of the surface of the centrifugal component 34 close to the first moving block 341. The first moving block 341 is internally rotatably connected to a limiting rod 343, and the interior of the limiting rod 343 is rotatably connected to the second moving block 342 through a movable rod 344. The interior of the movable rod 344 is rotatably connected to a displacement rod 345, and a centrifugal ball 346 is provided at the end of the displacement rod 345. The other end of the centrifugal component 34 is also provided with a limiting ring 347 to prevent the second moving block 342 from escaping.

[0041] When a polymerization reaction occurs inside the device, the centrifugal ball 346 rotates through the rotation of the centrifugal assembly 34. When the rotation rate reaches a certain level, the first moving block 341 begins to approach the second moving block 342, and the opening formed by the displacement rod 345 moves, driving the centrifugal ball 346 to rotate. When the rotation rate becomes lower, the first moving block 341 begins to move away from the second moving block 342 and begins to drop. At this time, the opening angles of the two displacement rods 345 change again. When polypropylene is too viscous, the second moving block 342 can be fixed to a suitable position of the centrifugal assembly 34. At this time, only the first moving block 341 moves and rotates on the surface of the centrifugal assembly 34.

[0042] A mounting plate 5 is provided on one side of the surface of the reaction tank 1 close to the first main pipeline 21 , and the number of the mounting plates 5 is four.

[0043] By setting the mounting plate 5, the device can be fixedly installed before use to prevent the device from tilting and sliding when working. The conventional reaction tank 1 is relatively large and needs to be fixedly installed.

[0044] The top of the reaction tank 1 is provided with a plurality of groups of first input pipes 6 in a circular array, and a pressure gauge 7 is provided in the middle of the top of the reaction tank 1 .

[0045] Pressure gauge 7 To monitor pressure changes in real time: The polymerization reaction of polypropylene is usually carried out under high temperature and high pressure to promote the formation and extension of polymer chains. Pressure gauge 7 can measure and monitor the pressure changes in the system in real time to ensure that the polymerization reaction is carried out within the set pressure range. This helps staff to promptly discover and solve possible pressure abnormalities and prevent possible failures and accidents.

[0046] A plurality of groups of second input pipes 8 are arranged on one side of the top of the reaction tank 1 close to the first input pipe 6 , and a one-way valve is arranged inside each of the second input pipes 8 .

[0047] The first input pipeline 6 and the second input pipeline 8 are used to ensure that materials can be input into the reaction tank 1 when the reaction tank 1 is working, so that propylene polymerization reaction can be carried out inside the reaction tank 1 to finally form polypropylene. A one-way valve is arranged inside the second input pipeline 8 to ensure that when the second input pipeline 8 transports things into the reaction tank 1, it prevents backflow.

[0048] A circulation pipe 9 is also provided on one side of the bottom surface of the reaction tank 1 close to the driving motor 4 , and a discharge valve is also provided on one side of the bottom surface of the reaction tank 1 close to the circulation pipe 9 .

[0049] The circulation pipeline 9 can be connected to the chamber formed by the first main pipeline 21 and the second sub-pipeline 22. At this time, the screened gaseous propylene can be cooled and circulated to the inside of the reaction tank 1 again through the pipeline. Because during the polymerization reaction, the temperature inside the reaction tank 1 is constantly changing, and the temperature inside the reaction tank 1 needs to be controlled. When the temperature inside the reaction tank 1 is overheated, the circulation pipeline 9 can be extended to reduce the temperature of the gaseous propylene passing through it before it is passed into the inside of the reaction tank 1. When the polymerization reaction temperature inside the reaction tank 1 becomes low, heat can be transported to the inside through the second input pipeline 8. When the device is not in use, the inside of the reaction tank 1 can be cleaned through the discharge valve.

[0051] Propylene, ethylene and hydrogen are introduced into the first input pipe 6 respectively, and then enter the cavity of the reaction tank 1. Then, the catalyst and gas pipeline are connected to the second input pipe 8 and introduced into the interior of the reaction tank 1. The pressure and temperature inside the reaction tank 1 are controlled. At this time, the pointer display on the pressure gauge 7 is always observed. When the driving motor 4 is working, it drives the first operating gear 33, the second operating gear 36 and the intermittent wheel 35 to operate. At this time, the gaseous propylene is liquefied in the interior of the reaction tank 1. At this time, the control rod 37 on the second operating gear 36 drives the intermittent wheel 35 to operate. The wheel 35 rotates intermittently. When the intermittent wheel 35 rotates, the second moving block 342 and the first moving block 341 on the centrifugal assembly 34 move up and down. The sliding friction force of the first moving block 341 on the centrifugal assembly 34 is smaller than that of the second moving block 342. At this time, the centrifugal ball 346 connected to the displacement rod 345 is rotated out by the centrifugal force. When the rotation force becomes smaller, the first moving block 341 descends, and the centrifugal ball 346 changes from an upper V shape to a lower V shape, vertically stirring the cavity of the reaction tank 1, so that the polypropylene gas inside the device is polymerized. At this time, the first operating tooth 33 rotates to drive The travel rod 322 works, so that the travel block 323 moves inside the limiting notch 321 opened by the pushing assembly 32. When the travel block 323 drives the travel tooth 324 to move to the tooth groove of the guide tooth 327, the travel tooth 324 starts to rotate, so that the lifting plate 325 drives the push plate 326 to start tilting. The push plate 326 and the lifting plate 325 are sloped surfaces. The push plate 326 fits the inner wall of the reaction tank 1 to guide the polymer to the side of the reaction tank 1 that is connected to the second auxiliary pipe 22. The polymer gas first passes through the guide hole 28 on the separation block 27 and finally passes through the second auxiliary pipe. The channel 22 is passed into the interior of the first main pipeline 21 to recycle the carrier gas, and the remaining polymer passes through the interior of the second sub-pipeline 22 to push the separation block 27 forward. When the impact force on the separation block 27 is too large, the separation block 27 will tilt forward a certain distance accordingly. When the separation block 27 moves forward, the interior of the storage chamber 29 is connected with the guide pipe 23, and the storage chamber 29 stores additives, which drives the closed block 26 to drain the coolant and the remaining additives in the guide pipe 23 into the interior of the second sub-pipeline 22, so as to cool and mix the polypropylene polymer.

The sliding friction force of the first moving block (341) on the centrifugal assembly (34) is less than The second moving block (342) rotates the centrifugal ball (346) connected to the displacement rod (345) out by centrifugal force. When the rotation force decreases, the first moving block (341) descends, and the centrifugal ball (346) changes from an upper V shape to a lower V shape, vertically stirring the cavity of the reaction tank (1) so that the polypropylene gas inside the device polymerizes. At this time, the first operating tooth (33) rotates to drive the travel rod (322) to work, so that the travel block (323) moves inside the limiting notch (321) opened by the pushing component (32). When the travel block (323) drives the travel tooth When (324) moves to the tooth groove of the guide tooth (327), the travel tooth (324) starts to rotate, so that the lifting plate (325) drives the push plate (326) to start to tilt. The push plate (326) and the lifting plate (325) are sloped surfaces. The push plate (326) fits the inner wall of the reaction tank (1) to guide the polymer to the side of the reaction tank (1) that is connected to the second auxiliary pipeline (22). The polymer gas first passes through the guide hole (28) on the separation block (27) and finally passes through the second auxiliary pipeline (22) into the pipeline of the first main pipeline (21). The carrier gas is recycled and the remaining The remaining polymer passes through the interior of the second sub-pipeline (22) and pushes the separation block (27) forward. When the impact force on the separation block (27) is too large, the separation block (27) will tilt forward a certain distance accordingly. When the separation block (27) moves forward, the interior of the storage chamber (29) is connected to the guide pipe (23), and the storage chamber (29) stores additives, which drives the closed block (26) to drain the coolant and the remaining additives in the guide pipe (23) into the interior of the second sub-pipeline (22), so that the polypropylene polymer is cooled and mixed, and then sent to the lower part of the processing procedure.
