Description

Technical Field

[0001] The invention belongs to the technical field of butanediol processing, and specifically relates to a continuous hydrolysis reaction device for 1,4-butanediol. Background Technique

[0002] As a crucial class of organic chemical raw materials, 1,4-butanediol plays an irreplaceable role in multiple fields. In the pesticide field, it is an important intermediate for synthesizing hexachlorocyclopentadiene and the organochlorine insecticide endosulfan. In the pharmaceutical aspect, it can be used to synthesize the main intermediate of vitamin B6, n-propyl dioxacycloheptane, and its derivatives can also be used to manufacture products such as plasticizers for alkyd resins and cross-linking agents for synthetic resins. With the continuous expansion and innovation of various application fields, the market demand for 1,4-butanediol has shown a rapid growth trend. There are not only higher requirements for quantity, but also higher standards for its quality and production efficiency. Currently, the preparation of 1,4-butanediol is mostly achieved through methods such as semi-hydrogenation of 1,4-butynediol (BYD), hydrolysis of 1,4-dichloro-2-butene, and 1,3-butadiene. Among them, the semi-hydrogenation method of 1,4-butynediol has become the most widely used process due to its mature technology and relatively easy availability of raw materials. However, regardless of the method used, the hydrolysis reaction link is crucial, and its reaction effect directly affects the output quality and efficiency of 1,4-butanediol. In the face of the continuously rising market demand and increasingly stringent environmental protection and cost control requirements, it is urgent to develop a new hydrolysis reaction device for 1,4-butanediol.

[0003] Most of the existing 1,4-butanediol hydrolysis reaction devices feed materials through a single feeding port, resulting in uneven feeding, which makes it easy for the raw materials to be unevenly distributed in the reaction chamber, leading to too high or too low local raw material concentration and affecting the uniformity and efficiency of the reaction. At the same time, most traditional devices are mainly operated in batches. This not only has low production efficiency and is difficult to fit the rhythm of large-scale industrial production, but also introduces more human operation errors due to frequent batch switching, resulting in batch-to-batch differences in product quality. Therefore, a continuous hydrolysis reaction device for 1,4-butanediol is proposed. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation of structures such as the conical drain plate and the sieve, the present invention facilitates the uniform dispersion of raw materials. Start the first motor to rotate the driving gear, the conical drain plate and the stirring paddle. After the raw materials enter the liquid separation holes corresponding to the feed ports, they will fall into the reaction chamber through the sieve in the leakage groove. At this time, some of the raw materials will directly fall into the water in the reaction chamber, while the other part will fall into the rotating conical drain plate and be evenly scattered into the water through the smaller-diameter leakage holes as the conical drain plate rotates, enabling the raw materials to be more evenly distributed in the water in the reaction chamber, increasing the contact area between the raw materials, water and subsequent catalyst, and being conducive to improving the uniformity and efficiency of the reaction. Among them, the stirring paddle and the side scrapers will agitate the water flow and scrape up the catalyst deposited at the bottom of the reaction chamber, enabling the water, raw materials and catalyst in the reaction chamber to be fully mixed, improving the utilization rate of the catalyst, enabling the reaction to proceed more fully, and being conducive to the effective collision between reactants, thereby accelerating the reaction rate, shortening the reaction time and improving the production efficiency; Through the cooperation of structures such as the liquid separation plate and the conical drain plate, the present invention facilitates the continuous feeding of raw materials. The rotating liquid separation plate divides and takes away the raw materials falling from the feed port, and then sends them into several leakage grooves in the first rotating groove respectively, and they fall into the reaction chamber through several sieves respectively, dispersing the concentrated raw material flow into multiple small streams. And multiple leakage grooves correspond to multiple feeding points, and the raw materials fall into the reaction chamber from different positions, increasing the distribution range of the raw materials in the reaction chamber, avoiding the problem of slow feeding speed caused by the feeding of raw materials at the same leakage groove, enabling the raw materials to be more evenly and quickly distributed at different positions in the reaction chamber, laying a foundation for the uniformity of subsequent reactions. And the evenly distributed raw materials help to reduce the concentration difference and temperature difference in different regions of the reaction chamber. At the same time, the rotation of the liquid separation plate enables the raw materials to continuously and stably enter the reaction chamber, avoiding the reaction fluctuations that may be brought by intermittent feeding; Through the cooperation of structures such as the filter plate and the rotating plate, the present invention improves the filtering effect of the device. The raw materials pass through the filtering of the filter plate into the liquid separation holes. At the same time, start the second motor, and through transmission, the rotating plate will rotate towards the direction close to the filter plate under the action of the elastic force of the spiral elastic member and the scroll elastic member, and finally collide with the bottom of the filter plate, applying an impact force to the filter plate to cause it to vibrate. Through vibration, the impurity particles on the filter plate are not easy to adhere and accumulate, reducing the risk of blockage of the filtering holes, so that the raw materials can pass through the filter plate into the liquid separation holes more smoothly, improving the filtering efficiency and effect, and ensuring the filtering quality of the raw materials.

[0024] Adopting the above solution: By setting up the cooperation of structures such as the conical orifice plate 103 and the sieve 205, it is convenient to evenly disperse the raw materials. Start the first motor 101 to rotate the driving gear 102, the conical orifice plate 103 and the stirring paddle 105. After the raw materials enter the liquid separation holes 110 corresponding to the feed port 202, they will fall into the reaction chamber 406 through the sieve 205 in the leakage groove 204. At this time, a part of the raw materials will directly fall into the water in the reaction chamber 406, while the other part falls into the rotating conical orifice plate 103 and is evenly scattered into the water through the smaller orifice holes 104 as the conical orifice plate 103 rotates, enabling the raw materials to be more evenly distributed in the water in the reaction chamber 406, increasing the contact area between the raw materials and water and subsequent catalyst, which is beneficial to improving the uniformity and efficiency of the reaction.

At the same time, the rotation of the liquid separation plate 108 enables the raw materials to continuously and stably enter the reaction chamber 406, avoiding the reaction fluctuations that may be brought about by intermittent feeding.

[0025] Such as Figures 3 to 8As shown in the figure, a vibration mechanism 3 is arranged inside the top cover mechanism 2. The vibration mechanism 3 is located on the side of the liquid separation mechanism 1. The vibration mechanism 3 includes a second motor 301. A half gear 302 is rotatably connected to the side of the second motor 301. A driven gear 303 is meshed with the side of the half gear 302. A rotating plate 304 is fixedly connected to the side of the driven gear 303 away from the second motor 301. Folding air bags 305 are arranged at both the bottom and the top of the rotating plate 304. A spiral elastic member 306 is arranged inside the folding air bag 305 located below the rotating plate 304. A scroll elastic member 307 is arranged at one end of the rotating plate 304 away from the driven gear 303. A filter plate 308 is arranged above the rotating plate 304. A plurality of filter holes 309 are evenly formed in the filter plate 308. The filter plate 308 is located on the side of the rotating plate 304 away from the half gear 302. One end of the rotating plate 304 away from the driven gear 303 abuts against the bottom of the filter plate 308. The upper and lower sides of the rotating plate 304 are fixedly connected to one side of the two folding air bags 305 away from the opening direction respectively.

[0026] The second motor 301 is fixedly connected between the inner wall of the top cover main body 201. The rotating plate 304 is rotatably connected between the second rotating grooves 207. The filter plate 308 is fixedly connected between the inner wall of the feed inlet 202. The side of the rotating plate 304 is elastically connected to the inner wall of the top cover main body 201 through the scroll elastic member 307. The interiors of the two folding air bags 305 communicate with each other through the ventilation grooves 208. One side of the two folding air bags 305 away from the rotating plate 304 is fixedly connected between the inner walls of the second rotating grooves 207 respectively. The folding air bag 305 provided with the spiral elastic member 306 is elastically connected to the inner wall of the second rotating groove 207 through the spiral elastic member 306. The size of the filter plate 308 is smaller than the size of the strainer 205. The size of the filter holes 309 is the same as the size of the small holes.

[0027] Adopting the above solution: By setting up the cooperation of structures such as the filter plate 308 and the rotating plate 304, the filtering effect of the device is improved. The raw material passes through the filter of the filter plate 308 and enters the liquid separation holes 110. At the same time, the second motor 301 is started to rotate the half gear 302. The rotation of the half gear 302 drives the driven gear 303 meshing with it to rotate, so that the rotating plate 304 rotates downward, squeezing the spiral elastic member 306 and the compressed scroll elastic member 307. At the same time, the gas in the folding airbag 305 below the rotating plate 304 enters the folding airbag 305 above it through the ventilation groove 208, so that both the upper and lower sides of the rotating plate 304 are blocked by the folding airbags 305 to prevent the raw material from entering the second rotating groove 207. When the gear on the half gear 302 rotates to the position where it disengages from the driven gear 303, the rotating plate 304 will rotate towards the filter plate 308 under the action of the elastic forces of the spiral elastic member 306 and the scroll elastic member 307, and finally collide with the bottom of the filter plate 308, applying an impact force to the filter plate 308 to cause it to vibrate. Through the vibration, the impurity particles on the filter plate 308 are not easily attached and accumulated, reducing the risk of blockage of the filter holes 309, so that the raw material can pass through the filter plate more smoothly into the liquid separation holes, improving the filtering efficiency and effect, and ensuring the filtering quality of the raw material.

[0028] The working principle and usage process of the present invention: First, the mixture of the catalyst and water is injected into the reaction chamber 406 through the water pipe 206, and the heater 403 is operated by the operation screen 402 to heat the water in the reaction chamber 406. Subsequently, the 1,4-dichloro-2-butene raw material is injected into the feed port 202, and it passes through the filter of the filter plate 308 and enters the liquid separation holes 110. At the same time, the second motor 301 is started to rotate the half gear 302. The rotation of the half gear 302 drives the driven gear 303 meshing with it to rotate, so that the rotating plate 304 rotates downward, squeezing the spiral elastic member 306 and the compressed scroll elastic member 307. At the same time, the gas in the folding airbag 305 below the rotating plate 304 enters the folding airbag 305 above it through the ventilation groove 208, so that both the upper and lower sides of the rotating plate 304 are blocked by the folding airbags 305 to prevent the raw material from entering the second rotating groove 207. When the gear on the half gear 302 rotates to the position where it disengages from the driven gear 303, the rotating plate 304 will rotate towards the filter plate 308 under the action of the elastic forces of the spiral elastic member 306 and the scroll elastic member 307, and finally collide with the bottom of the filter plate 308, applying an impact force to the filter plate 308 to cause it to vibrate; Start the first motor 101 to rotate the driving gear 102, the conical leakage plate 103 and the stirring paddle 105. After moving away and entering the liquid separation holes 110 corresponding to the feed port 202, it will fall into the interior of the reaction chamber 406 through the screen 205 in the leakage tank 204. At this time, a part of the raw materials will directly fall into the water in the reaction chamber 406, while the other part will fall into the rotating conical leakage plate 103 and be evenly scattered into the water through the smaller leakage holes 104 as the conical leakage plate 103 rotates. Among them, the stirring paddle 105 and the side scraper 106 will stir the water flow and scrape up the catalyst deposited at the bottom of the reaction chamber 406 to make it fully contact with the principle. When the raw materials enter the water, they will undergo a decomposition reaction with water under the action of the catalyst and high temperature. The chemical equation is: ; At the same time, when the driving gear 102 rotates, it will drive the liquid separation plate 108 to rotate in the first rotating groove 203 through the transmission gear 107 and the teeth 109, so that several liquid separation holes 110 on the liquid separation plate 108 respectively pass under the feed port 202, divide and carry away the raw materials falling from the feed port 202, and then send them into several leakage tanks 204 in the first rotating groove 203 respectively, and make them fall into the interior of the reaction chamber 406 through several screens 205 respectively, and be more evenly scattered into the water under the rotation of the conical leakage plate 103, dispersing the concentrated raw material flow into multiple small streams. And multiple leakage tanks 204 correspond to multiple feed points, and the raw materials fall into the reaction chamber 406 from different positions, increasing the distribution range of the raw materials in the reaction chamber 406. When performing a small amount of reaction work, the expansion rod 210 can be driven by the air cylinder 209 to lift the transmission gear 107, so that the transmission gear 107 is disengaged from the driving gear 102 and the teeth 109. At this time, the raw materials will only enter the interior of the reaction chamber 406 through one screen 205. Finally, after the reaction is completed, only need to open the valve 405 to discharge the reaction mixture through the discharge port 404. Among them, the side scraper 106 can also clean the inner wall of the reaction chamber 406.
