Description

Technical Field

[0001] The present application relates to the field of triethylene glycol, and in particular to a triethylene glycol production increasing device. Background Art

[0002] Triethylene glycol (also known as triethylene glycol, abbreviated as TEG) can be used as a solvent for the extraction of aromatic hydrocarbons, a solvent for rubber and nitrocellulose, a diesel additive, and a rocket fuel. In addition, it has a wide range of uses in the pharmaceutical, coating, textile, printing and dyeing, food, papermaking, cosmetics, leather making, photography, printing, metal processing and other industries.

[0003] In the existing production equipment for triethylene glycol, the inventors believe that diethylene glycol and triethylene glycol are by-products of the production of monoethylene glycol, which are proportional to the output of ethylene glycol.

[0018] In summary, the present invention includes at least one of the following beneficial technical effects: 1. Triethylene glycol is produced by setting up a production device. MEG cooling tank and DEG cooling tank cool MEG and DEG. The feed pump is responsible for conveying the mixed raw materials to the reaction tank. The feed port of the feed pump is fixedly connected to the outer surface of the MEG cooling tank and the DEG cooling tank through a feed pipe with a valve. The design of the valve makes the flow control more flexible. The temperature sensor monitors the temperature of the liquid in the MEG cooling tank and the DEG cooling tank. The feed pump conveys the mixture into the reaction tank through a pipe fixedly connected to the discharge port. The steam port of the reboiler is connected to the reaction tank through a pipe with a valve to adjust the flow of steam. The reaction tank is connected to the reaction tank through a pipe. The reactants are transported to a fixedly connected separation pump, and the rotating ring is rotatably connected to the separation tube and the connecting tube, so that the reactants are transported to the MEG tower and the DEG tower through the separation tube and the connecting tube. The fixedly connected pipeline on the feed port of the return pump is fixedly connected to the outer surfaces of the MEG tower and the DEG tower, respectively. Flexible adjustment is achieved through the pipeline with a valve, so that the unqualified products can be transported to the feed pipe through the pipeline for re-reaction. This solves the technical problem that in the production equipment for triethylene glycol, diethylene glycol and triethylene glycol are by-products of the production of monoethylene glycol, which are proportional to the output of ethylene glycol. Theoretically, the output of by-products is extremely low if the reaction conditions are precisely controlled.

[0019] 2. By setting up a mixing device, diethylene glycol and triethylene glycol are mixed. The fixed frame is rotatably connected to the water wheel pipe rack, which is fixed without affecting its rotation. When the liquid flows through the water wheel pipe rack, the kinetic energy of the fluid will act on the blades of the water wheel pipe rack. When the fluid flows, the speed and pressure of the water will exert force on the blades to promote their rotation. The water wheel pipe rack is fixedly installed on the rotating frame to drive them to rotate synchronously. When the rotating frame rotates, it drives the rotating connected mixing plate to revolve. Since the mixing gear is meshed with the gear ring, it rotates, so that the material is continuously stirred and mixed when the fluid passes through, which solves the technical problem that in the production equipment for triethylene glycol, uneven mixing of raw materials may affect the uniformity and efficiency of the reaction, thereby reducing the quality of the product.

[0020] 3. By setting an adjustment device, the flow rate of the liquid is adjusted. The motor drives the driving gear to rotate. Since it meshes with the gear of the rotating ring, the rotating ring is driven to rotate. An adjustment hole is opened on the circular plate. The design of the hole is convenient for the fluid to pass through. The circular plate is rotatably connected with the rotating gear and the rotating gear. Since the rotating gear meshes with the gear of the rotating ring, the rotation of the rotating ring drives the rotating gear to rotate, thereby driving the rotating gear meshed with the rotating gear to rotate. The outer surfaces of the rotating gear and the rotating gear are provided with a rotating groove. Since the rotating groove is slidably connected with the adjustment plate, the rotation of the rotating gear and the rotating gear drives them to move in the sliding limit groove, thereby adjusting the size of the adjustment hole to control the flow rate of the fluid. This solves the technical problem that in the production equipment for triethylene glycol, the fluctuation of feed flow rate will lead to unstable temperature and pressure, and it cannot be adjusted in time according to the characteristics of the raw materials or changes in process conditions, thereby reducing the production flexibility.

The feed port of the separation pump 42 is fixedly connected to the outer surface of the reaction tank 31 through a pipeline, and the discharge port of the separation pump 42 is fixedly connected to a separation pipe 43. The outer surface of the separation pipe 43 is rotatably connected to a rotating ring 44 with a gear, and one end of the rotating ring 44 is rotatably connected to a connecting pipe 45. The MEG tower 4 is used to separate diethylene glycol from the reaction mixture, and the DEG tower 41 is used to separate triethylene glycol from the reaction mixture.

[0029] Specifically, in order to transport the unqualified products to the feed pipe 23 through the pipeline for re-reaction, the outer surface of one connecting pipe 45 is fixedly connected to the outer surface of the MEG tower 4, and the outer surface of the other connecting pipe 45 is fixedly connected to the outer surface of the DEG tower 41.

[0030] like Figure 5-Figure 7 As shown, in order to mix diethylene glycol and triethylene glycol, a mixing device is provided. The mixing device is located on the outer surface of the frame 1 and mixes diethylene glycol and triethylene glycol. The mixing device includes a water wheel pipe rack 61 and a rotating rack 62. The rotation of the water wheel pipe rack 61 drives the rotating rack 62 to rotate.

[0031] Specifically, in order to drive the rotating frame 62 to rotate through the water wheel tube rack 61, the mixing device also includes a fixed frame 6, which is fixedly installed on the inner wall of the feed pipe 23, and the inner wall of the groove of the fixed frame 6 is rotatably connected to the outer surface of the water wheel tube rack 61. The outer surface of the water wheel tube rack 61 is fixedly installed with the outer surface of the rotating frame 62. The fixed frame 6 is rotatably connected to the water wheel tube rack 61, and its rotation is not affected while being fixed. When the liquid flows through the water wheel tube rack 61, the kinetic energy of the fluid will act on the blades of the water wheel tube rack 61. When the fluid flows, the speed and pressure of the water will exert force on the blades to drive them to rotate. The water wheel tube rack 61 is fixedly installed with the rotating frame 62, and they are fixed so as to drive them to rotate synchronously.

[0032] Specifically, in order to continuously stir and mix the substances when the fluid passes through, a gear ring 7 is fixedly installed on the inner wall of the feed pipe 23, and a mixing plate 71 is rotatably connected to the inner wall of the groove of the rotating frame 62. A mixing gear 72 is fixedly installed on the outer surface of the mixing plate 71. The mixing gear 72 is meshed with the gear ring 7. When the rotating frame 62 rotates, the rotatably connected mixing plate 71 is driven to revolve. Since the mixing gear 72 is meshed with the gear ring 7, it rotates on its own, thereby continuously stirring and mixing the substances when the fluid passes through.

[0033] like Figure 8-Figure 11 As shown, in order to adjust the flow rate of the liquid, an adjusting device is provided. The adjusting device is located on the outer surface of the frame 1 and adjusts the flow rate of the liquid. The adjusting device includes an adjusting hole 83 and an adjusting plate 93. The movement of the adjusting plate 93 adjusts the size of the adjusting hole 83.

[0034] Specifically, in order to enable the motor 8 to drive the driving gear 81 to rotate, the adjusting device also includes a motor 8, which is fixedly mounted on the outer surface of the separation tube 43, and the output shaft of the motor 8 is fixedly mounted with a driving gear 81, and the driving gear 81 is meshed with the gear of the rotating ring 44, and the inner wall of the rotating ring 44 is rotatably connected with a circular plate 82, and an adjusting hole 83 is provided on the outer surface of the circular plate 82. The motor 8 is fixedly mounted on the separation tube 43 and fixed thereto, and the motor 8 drives the driving gear 81 to rotate, and since it is meshed with the gear of the rotating ring 44, the rotating ring 44 is driven to rotate, and the rotating ring 44 is rotatably connected with the circular plate 82, and the rotation of the rotating ring 44 does not affect the circular plate 82, and an adjusting hole 83 is provided on the circular plate 82, and the hole is designed to facilitate the passage of fluid.

[0035] Specifically, in order to drive the rotating gear 91 meshing with the rotating gear 9 to rotate, the outer surface of the circular plate 82 is rotatably connected with the rotating gear 9 and the rotating gear 91 respectively, the rotating gear 9 is meshed with the rotating gear 91, and the rotating gear 9 is meshed with the gear of the rotating ring 44. A limiting groove 92 is provided on the outer surface of the circular plate 82, and the inner wall of the groove of the limiting groove 92 is slidably plugged into the outer surface of the adjusting plate 93. The circular plate 82 is rotatably connected with the rotating gear 9 and the rotating gear 91, and while the two are fixed, their rotation does not affect the circular plate 82. Since the rotating gear 9 is meshed with the gear of the rotating ring 44, the rotation of the rotating ring 44 drives the rotating gear 9 to rotate, thereby driving the rotating gear 91 meshing with the rotating gear 9 to rotate, and the limiting groove 92 is slidably plugged into the adjusting plate 93, fixing it while not affecting its movement, so that the size of the adjusting hole 83 can be adjusted by moving the adjusting plate 93.

[0036] Specifically, in order to adjust the size of the adjustment hole 83 so as to control the flow rate of the fluid, a rotation groove 94 is provided on the outer surface of the rotating gear 9 and the outer surface of the rotating gear 91. The inner wall of the groove of the rotating groove 94 is slidably connected with the outer surface of the adjustment plate 93. The rotating groove 94 is provided on the outer surface of the rotating gear 9 and the rotating gear 91. Since the rotating groove 94 is slidably connected with the adjustment plate 93, the rotation of the rotating gear 9 and the rotating gear 91 drives them to move in the sliding limit groove 92, thereby adjusting the size of the adjustment hole 83 so as to control the flow rate of the fluid.

[0037] Working principle: When diethylene glycol and triethylene glycol need to be produced, the liquid is cooled in the MEG cooling tank 2 and the DEG cooling tank 21, and the temperature sensor 3 monitors the temperature of the liquid. When the appropriate temperature is reached, the feed pump 22 is started to suck the liquid through the feed pipe 23 fixedly connected to the MEG cooling tank 2 and the DEG cooling tank 21, and the valve on the feed pipe 23 controls the flow rate of the liquid; When the diethylene glycol and triethylene glycol entering the feed pipe 23 need to be mixed, when the liquid flows through the water wheel pipe rack 61 rotatably connected to the feed pipe 23, the kinetic energy of the fluid will act on the blades of the water wheel pipe rack 61. When the fluid flows, the speed and pressure of the water will exert force on the blades, driving them to rotate, driving the rotating rack 62 fixedly mounted thereto to rotate, and driving the rotatably connected mixing plate 71 to revolve. Since the mixing gear 72 is meshed with the gear ring 7, it rotates on its own, thereby continuously stirring and mixing the substances when the fluid passes through; After the mixing is completed, the liquid enters the feed pump 22, and is transported to the reaction tank 31 through the pipeline of the discharge port of the feed pump 22. The steam port of the reboiler 32 is connected to the reaction tank 31 through a pipeline with a valve to adjust the flow of steam and maintain the temperature required for the reaction. After the reaction is completed, the separation pump 42 is started to suck the liquid through the pipeline fixedly connected to the reaction tank 31 through its feed port, and then transported to the connecting pipe 45 through the separation pipe 43 fixedly connected to the discharge port. The connecting pipe 45 is fixedly connected to the MEG tower 4 and the DEG tower 41 respectively, and is used to transport the reactants therein and separate them; When it is necessary to adjust the feed flow rate entering the MEG tower 4 and the DEG tower 41, the start motor 8 drives the driving gear 81 to rotate. Since it meshes with the gear of the rotating ring 44, the rotating ring 44 is driven to rotate. The gear inside the rotating ring 44 meshes with the rotating gear 9 rotatably connected to the circular plate 82, driving it to rotate, driving the rotating gear 91 meshed with it to rotate on the rotatably connected circular plate 82. The rotating gear 9 and the rotating gear 91 are provided with a rotating groove 94 on the outer surface, driving them to rotate together, thereby driving the adjustment plate 93 slidably plugged with the rotating groove 94 to move in the sliding plug-in limit groove 92, and the size of the adjustment hole 83 is adjusted as needed; In the MEG tower 4 and the DEG tower 41, diethylene glycol and triethylene glycol are extracted respectively according to different boiling points. When the detection is unqualified, the return pump 5 is started, and the fixedly connected pipeline on the feed port of the return pump 5 is fixedly connected with the outer surface of the MEG tower 4 and the DEG tower 41 respectively, and flexible adjustment is achieved through the pipeline with a valve, so that the unqualified product is transported to the feed pipe 23 through the pipeline for re-reaction.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
