[0001] This utility model relates to the field of ethylene glycol hydrogenation reactor technology, and in particular to an ethylene glycol hydrogenation reactor. Background Technology

[0002] In the chemical production field, the hydrogenation reaction of ethylene glycol is a crucial process, widely used in the production of many important chemical products such as polyester and antifreeze. With the rapid development of the chemical industry, more stringent requirements have been placed on the efficiency of the ethylene glycol hydrogenation reaction, product quality, and the stability of the production process.

[0003] Traditional ethylene glycol hydrogenation reactors have revealed many problems in practical applications. The mixing effect of their reaction components is poor, resulting in insufficient contact of reactants and an uneven and incomplete reaction. This not only reduces reaction efficiency but also affects the quality and purity of the product. Furthermore, during the reaction, some reactants adhere to the inner wall of the reaction vessel, affecting the overall reaction conversion rate. Based on this, an ethylene glycol hydrogenation reactor is proposed to solve the above problems. Summary of the Invention

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.

[0025] Example 1

[0026] Traditional ethylene glycol hydrogenation reactors have revealed numerous problems in practical applications. The mixing effect of their reaction components is poor, resulting in insufficient contact between reactants and an uneven and incomplete reaction. This not only reduces reaction efficiency but also affects product quality and purity. Furthermore, during the reaction, some reactants adhere to the inner wall of the reaction vessel, impacting the overall reaction conversion rate. This embodiment provides an ethylene glycol hydrogenation reactor. Please refer to Figures 1-5. The embodiment provides an ethylene glycol hydrogenation reactor, including a device body 1. The device body 1 is provided with a connecting mechanism 2, which includes connecting components 21 disposed on both sides of the device body 1. A reaction component 22 is disposed in the middle section of the device body 1, and a filter component 23 is disposed in the lower section of the device body 1. The reaction component 22 includes components fixedly installed on the device body. The reaction vessel 221 is located on the inner wall of the middle section of the body 1. A top plug 222 is fitted on the inner wall of the top of the reaction vessel 221. A fixed frame 223 is fixedly connected to the middle section of the bottom of the reaction vessel 221. A drive motor 224 is fixedly installed on the inner side of the fixed frame 223. A rotating shaft 225 is fixedly connected to the output end of the drive motor 224. A fixed sleeve 226 is fixedly connected to the outer wall of the middle section of the rotating shaft 225. A hinged connecting rod 227 is hinged to the outer wall of the fixed sleeve 226. A limit slider 228 is hinged to the outer end of the hinged connecting rod 227. A scraper 229 is fixedly connected to the upper and lower ends of the limit slider 228. An annular limit strip 2210 is fixedly connected to the inner wall of the middle section of the reaction vessel 221. A fixed rod 2211 is fixedly connected to the outer wall of the upper section of the rotating shaft 225. A sliding block 2212 is slidably connected to the inner wall of the fixed rod 2211. A rotating roller 2213 is rotatably connected to the bottom of the sliding block 2212.

[0027] In this embodiment, the reaction vessel 221, fixedly installed on the inner wall of the middle section of the device body 1, is the main reaction site; the top plug 222 fitted on the inner wall of the top of the reaction vessel 221 serves as a seal to prevent material leakage and the entry of external impurities during the reaction process; the fixed bracket 223 fixedly connected to the middle section of the bottom of the reaction vessel 221 is used to stably support the drive motor 224. Here, a three-phase asynchronous motor of model Y2-132M-4 is selected as the drive motor 224. This model of motor has the characteristics of moderate power, stable speed, and high reliability, which can meet the stirring requirements of the reactor; the rotating shaft 225 connected to the output end of the drive motor 224 passes through the inner wall of the bottom of the reaction vessel 221 and achieves a rotatable connection. When the drive motor 224 starts, it drives the rotating shaft 225 to rotate; the fixed sleeve 226 on the outer wall of the middle section of the rotating shaft 225 rotates accordingly, and the hinged connecting rod 227 hinged to the outer wall of the fixed sleeve 226 will irregularly sway and deflect with the rotation of the rotating shaft 225; the hinged connecting rod 227 A limiting slide groove is provided on the outer side of the limiting slider 228, which is hinged at the outer end. This limiting slide groove is slidably connected to the outer wall of the annular limiting strip 2210, which is fixedly connected to the inner wall of the middle section of the reaction vessel 221. This structural design allows the limiting slider 228 to only move in a circle along the annular limiting strip 2210. At the same time, in conjunction with the shaking of the hinged connecting rod 227, the scraper 229, which is fixedly connected to the upper and lower ends of the limiting slider 228, slides on the inner wall of the reaction vessel 221. The scraper 229 can scrape the material on the inner wall of the reaction vessel 221, preventing the material from adhering to the vessel wall and ensuring that the material is fully mixed and reacted. A sliding block 2212 is slidably connected to the inner wall of the fixed rod 2211, which is fixedly connected to the outer wall of the upper section of the rotating shaft 225. The rotating roller 2213, which is rotatably connected to the bottom of the sliding block 2212, will roll in the material when the rotating shaft 225 rotates, further enhancing the stirring effect of the material, allowing the reactants to come into fuller contact, accelerating the reaction rate, and improving the uniformity and thoroughness of the reaction.

[0028] Furthermore, the rotating shaft 225 is rotatably connected to the inner wall of the bottom of the reaction vessel 221; the limiting slider 228 has a limiting groove on its outer side, and its limiting groove is slidably connected to the outer wall of the annular limiting strip 2210; the scraper 229 is slidably connected to the inner wall of the reaction vessel 221; and the hinged connecting rod 227 swings and deflects irregularly up and down with the rotating shaft 225.

[0029] Furthermore, the rotating shaft 225 connected to the output end of the drive motor 224 passes through the inner wall of the bottom of the reaction vessel 221 and achieves a rotatable connection. When the drive motor 224 starts, it drives the rotating shaft 225 to rotate. The fixed sleeve 226 on the outer wall of the middle section of the rotating shaft 225 rotates accordingly. The hinged connecting rod 227, which is hinged to the outer wall of the fixed sleeve 226, will irregularly sway and deflect with the rotation of the rotating shaft 225. The limiting slider 228, which is hinged to the outer end of the hinged connecting rod 227, has a limiting groove on its outer side. This limiting groove is slidably connected to the outer wall of the annular limiting strip 2210 fixedly connected to the inner wall of the middle section of the reaction vessel 221. This structural design allows the limiting slider 228 to only make circumferential movements along the annular limiting strip 2210. At the same time, in conjunction with the swaying of the hinged connecting rod 227, it drives the scraper 229 fixedly connected to the upper and lower ends of the limiting slider 228 to slide on the inner wall of the reaction vessel 221.

[0030] Example 2

[0031] Based on Embodiment 1, the connecting component 21 includes mounting plates 211 fixedly connected to both sides of the outer wall of the device body 1, a water tank 212 fixedly mounted on the top of the mounting plate 211, and a pump pipe 213 connected to the inner wall of the water tank 212; the filtering component 23 includes a connecting discharge pipe 231, a filter box 232 connected to the bottom of the connecting discharge pipe 231, and a filter plate 233 fixedly mounted on the inner wall of the filter box 232.

[0032] In this embodiment, the water tank 212 is used to store auxiliary liquids required during the reaction process, such as coolant or reaction promoters. The pump pipe 213 transports the liquid in the water tank 212 to the top and sides of the reaction tank 221. During the reaction, these liquids can play a role in regulating the reaction temperature and promoting the reaction. By precisely controlling the flow rate and delivery time of the pump pipe 213, the reaction conditions can be effectively controlled. After the reaction is completed, the product enters the filter assembly 23 through the connecting discharge pipe 231 located on both sides of the bottom of the reaction tank 221. The filter assembly 23 includes the connecting discharge pipe 231, the filter box 232, and the filter plate 233 fixedly installed on the inner wall of the filter box 232. After the product falls into the filter box 232 through the connecting discharge pipe 231, the filter plate 233 filters the product, intercepting the impurities to obtain a relatively pure product, which is convenient for subsequent collection and processing. Throughout the process, the components work closely together to achieve integrated and efficient operation of the ethylene glycol hydrogenation reaction from raw material processing, reaction process to product filtration.

[0033] Furthermore, the other end of the pump pipe 213 is connected to both sides of the top of the reaction vessel 221; the connecting discharge pipe 231 is connected to both sides of the bottom of the reaction vessel 221.

[0034] Furthermore, during the reaction process, these liquids can regulate the reaction temperature and promote the reaction. By precisely controlling the flow rate and delivery time of the pump pipe 213, the reaction conditions can be effectively controlled. After the reaction is completed, the product enters the filter assembly 23 through the connecting discharge pipes 231 located on both sides of the bottom of the reaction tank 221. The filter assembly 23 includes the connecting discharge pipes 231, the filter box 232, and the filter plates 233 fixedly installed on the inner wall of the filter box 232. After the product falls into the filter box 232 through the connecting discharge pipes 231, the filter plates 233 filter the product, intercepting the impurities and obtaining a relatively pure product.

[0035] Working principle: First, the connecting component 21 in the connecting mechanism 2 consists of a mounting plate 211 fixedly connected to both sides of the outer wall of the device body 1, a water tank 212 on the top of the mounting plate 211, and a pump pipe 213 connected to the inner wall of the water tank 212. The water tank 212 is used to store auxiliary liquids required in the reaction process, such as coolant or reaction promoter. The pump pipe 213 transports the liquid in the water tank 212 to both sides of the top of the reaction tank 221. In the reaction process, these liquids can play a role in regulating the reaction temperature and promoting the reaction. By precisely controlling the flow rate and delivery time of the pump pipe 213, the reaction conditions can be effectively controlled.

[0036] The core reaction component 22, the reaction tank 221, which is fixedly installed on the inner wall of the middle section of the device body 1, is the main reaction site. The top plug 222 fitted on the inner wall of the top of the reaction tank 221 serves as a seal to prevent material leakage and the entry of external impurities during the reaction. The fixed bracket 223 fixedly connected to the middle section of the bottom of the reaction tank 221 is used to stably support the drive motor 224. Here, a three-phase asynchronous motor of model Y2-132M-4 is selected as the drive motor 224. This model of motor has the characteristics of moderate power, stable speed, and high reliability, which can meet the stirring requirements of the reactor. The rotating shaft 225 connected to the output end of the drive motor 224 passes through the inner wall of the bottom of the reaction tank 221 and achieves a rotatable connection. When the drive motor 224 starts, it drives the rotating shaft 225 to rotate.

[0037] The fixed sleeve 226 on the outer wall of the middle section of the rotating shaft 225 rotates accordingly. The hinged connecting rod 227, which is hinged to the outer wall of the fixed sleeve 226, will swing and deflect irregularly up and down with the rotation of the rotating shaft 225. The limiting slider 228, which is hinged to the outer end of the hinged connecting rod 227, has a limiting groove on its outer side. The limiting groove is slidably connected to the outer wall of the annular limiting strip 2210, which is fixedly connected to the inner wall of the middle section of the reaction vessel 221. This structural design makes the limiting slider 228 only able to make circumferential movements along the annular limiting strip 2210. At the same time, in conjunction with the shaking of the hinged connecting rod 227, it drives the scraper 229, which is fixedly connected to the upper and lower ends of the limiting slider 228, to slide on the inner wall of the reaction vessel 221. The scraper 229 can scrape the material on the inner wall of the reaction vessel 221 to prevent the material from adhering to the tank wall and ensure that the material is fully mixed and reacted.

[0038] The upper section of the rotating shaft 225 is fixedly connected to the outer wall of the fixing rod 2211, and the inner wall of the fixing rod 2211 is slidably connected to the sliding block 2212. The bottom of the sliding block 2212 is rotatably connected to the rotating roller 2213. When the rotating shaft 225 rotates, the rotating roller 2213 will roll in the material, further enhancing the stirring effect of the material, enabling the reactants to come into full contact, accelerating the reaction rate, and improving the uniformity and thoroughness of the reaction.

[0039] After the reaction is completed, the product enters the filter assembly 23 through the connecting discharge pipes 231 located on both sides of the bottom of the reaction vessel 221. The filter assembly 23 includes the connecting discharge pipes 231, the filter box 232, and the filter plates 233 fixedly installed on the inner wall of the filter box 232. After the product falls into the filter box 232 through the connecting discharge pipes 231, the filter plates 233 filter the product, intercepting the impurities and obtaining a relatively pure product, which is convenient for subsequent collection and processing. Throughout the process, the components work closely together to achieve integrated and efficient operation of the ethylene glycol hydrogenation reaction from raw material processing, reaction proceeding to product filtration.
