Description

Technical Field

[0001] The present invention relates to the technical field of furfuryl alcohol processing, and in particular to a device and a method for producing furfuryl alcohol by utilizing a supergravity reactor. Background Art

[0002] Furfuryl alcohol is an important organic solvent and chemical raw material, widely used in the pharmaceutical, pesticide, coating, dye and other industries. The supergravity reactor uses the centrifugal force generated by rotation to accelerate the reaction rate. In high-speed rotating equipment, the centrifugal force generated by rotation can be as high as 1,000 times the gravity. Driven by the strong centrifugal force, the mixing and transfer of materials are greatly enhanced, thereby significantly accelerating chemical reactions or other mass transfer and heat transfer processes that are limited by the mixing and transfer speed of materials. Furfuryl alcohol is prepared using a supergravity reactor during processing.

[0003] In the prior art, when producing furfural alcohol in an ultra-gravity reactor, furfural and hydrogen need to be quickly mixed by centrifugal rotation. Before adding furfural and hydrogen, furfural needs to be purified. When purifying furfural, it is first mixed with sodium hydroxide solution and then washed with water to remove residual alkali solution and desalted inorganic salts. After washing, it is dehydrated and then purified by steam stripping. However, when purifying by the existing steam stripping method, the steam input position is fixed and cannot contact the furfural solution from different positions and heights, which easily leads to uneven gas-liquid contact and affects the heat transfer efficiency. At the same time, it is easy to cause local overheating and trigger high-temperature polymerization of furfural or produce dead corners, resulting in residual furfural solution, which is inconvenient to use.

[0015] A method for producing furfuryl alcohol using a high-gravity reactor comprises the following steps:

[0016] S1, the furfural solution after washing is loaded into the purification tank through the feed port, so that steam is discharged from the vent and contacts the furfural solution;

[0017] S2. When the steam contacts the furfural solution, the aeration assembly is driven to move the air outlet up and down through the hollow rod and the movable cylinder, and the hollow rod is rotated at the same time. The rotation of the hollow rod causes the air outlet to move in a circular motion along the hollow rod, thereby allowing the steam to contact the furfural solution at different heights, horizontal and vertical positions;

[0018] S3, driving the aeration assembly to rotate the rectangular block, which in turn rotates the crushing plate, thereby cutting the bubbles generated when steam is added;

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] First, the device can rotate the movable rod by setting a motor. The rotation of the movable rod will cause the movable column to move up and down through the reciprocating threaded guide sleeve. The up and down movement of the movable column will cause multiple air outlets to move up and down through the hollow rod. At the same time, the rotation of the movable rod will cause the movable column to rotate. The rotation of the movable column will cause multiple air outlets to perform circular motion with the movable column as the center through the hollow rod. At this time, since the lifting cylinder is relatively stationary, the hollow rod will rotate while performing the circular motion. The rotation of the hollow rod will cause the air outlet to rotate, thereby causing the steam to contact the furfural solution at different heights, levels and vertical positions, thereby expanding the heat transfer area, improving the purification efficiency, and avoiding local overheating that causes furfural decomposition or dead corners that cause furfural residue.

[0022] Secondly, this device can make the rectangular block move up and down with the moving column by arranging the I-shaped ring, the annular block, the fixed plate and the moving rod. The up and down movement of the rectangular block will cause the crushing plate to move up and down through the fixed column, so that the crushing plate is always above the air outlet. At the same time, the rotation of the movable rod will cause the rectangular block to rotate through the first circular gear, the second circular gear, the third circular gear and the driven rod. The rotation of the rectangular block will cause the crushing plate to rotate through the fixed column, thereby cutting the bubbles generated when steam is added, thereby refining the bubble size, increasing the gas-liquid contact area, effectively improving the purification efficiency, and enhancing the separation effect.

[0023] Third: This device ensures the crushing effect of the crushing rod while reducing the rotation speed of the movable sleeve by setting the first circular gear, the second circular gear and the third circular gear, thereby avoiding excessive stirring speed causing violent turbulence of the liquid, and then forming a large amount of foam or splashing droplets.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Figures 1-8 The best embodiment of the present invention is shown below in conjunction with the attached Figures 1-8 The present invention is further described.

[0035] The device for producing furfuryl alcohol using a high-gravity reactor comprises a high-gravity reactor body 1, a transfer tank 2, a condenser 3 and a purification tank 4 being provided on the left side of the high-gravity reactor body 1, wherein the transfer tank 2, the pipe side of the condenser 3 and the purification tank 4 are connected in sequence, the top of the purification tank 4 is provided with a feed port 6 and an air outlet pipe 9, both of which are provided with valves, the air outlet pipe 9 is connected to the pipe side inlet of the condenser 3, the bottom of the purification tank 4 is provided with a sewage outlet 40, which is also provided with a valve, a pressure relief pipe 5 containing a valve is fixed to the side of the purification tank 4, and a uniform jet mechanism is provided on the purification tank 4. The high-gravity reactor body 1, the transfer tank 2 and the condenser 3 are all prior art and relatively mature, and their connection and installation methods and methods of use are not described in detail here.

[0036] The uniform jet mechanism includes two hollow rods 16 and four fixed columns 37 arranged in the purification tank 4. The two hollow rods 16 are both arranged at the lower part of the purification tank 4, and the two hollow rods 16 are both arranged along the radial direction of the purification tank 4. The sides of the two hollow rods 16 are provided with multiple connecting holes. The outer walls of the two hollow rods 16 are radially installed with multiple movable cylinders 17 connected to the connecting holes, and the sides of the multiple movable cylinders 17 are provided with multiple air outlet holes 18. The four fixed columns 37 are all arranged on the upper side of the hollow rods 16, and the four fixed columns 37 are all arranged along the axial direction of the purification tank 4. The four fixed columns 37 are arranged in a ring, and multiple crushing plates 38 are installed at the bottom of the four fixed columns 37. The purification tank 4 is provided with a driving and aeration assembly that moves the two hollow rods 16 and the four fixed columns 37.

[0037] By means of the above structure, when in use, steam can be ejected from multiple air outlets 18, and the two hollow rods 16 can be moved up and down by driving the aeration component. When the hollow rods 16 move up and down, the movable cylinder 17 will be driven to move up and down, thereby causing the air outlet 18 to move up and down, so that the steam contacts the furfural solution at different heights. At the same time, driving the aeration component can cause the hollow rods 16 to rotate around the axis of the purification tank 4 and at the same time around its own axis, thereby causing the steam to contact the furfural solution at different horizontal and vertical positions, thereby expanding the heat transfer area and improving the purification efficiency, while avoiding local overheating that causes furfural decomposition or dead corners that cause furfural residue. At the same time, driving the aeration component will cause the fixed column 37 to rotate around its own axis, and the rotation of the fixed column 37 will cause the crushing plate 38 to rotate, thereby cutting the bubbles generated when the steam is added, thereby refining the bubble size, increasing the gas-liquid contact area, effectively improving the purification efficiency, and enhancing the separation effect.

[0038] like Figure 3-5As shown, the driving gas filling component includes a movable sleeve 10 rotatably installed on the top of the purification tank 4 through a first sealing component, and the sealing component can be mechanically sealed. A lifting plate 26 is provided above the purification tank 4, and a moving column 11 is rotatably installed on the lifting plate 26. The lower part of the moving column 11 passes through the movable sleeve 10 and extends into the purification tank 4. The two hollow rods 16 are rotatably connected to the moving column 11 through a second sealing component. A moving block 12 is axially installed on one side of the upper part of the moving column 11. A moving groove that matches the moving block 12 is provided on the inner wall of the movable sleeve 10, so that the moving column 11 and the movable sleeve 10 rotate synchronously, and the moving column 11 and the movable sleeve 10 can move relative to each other in the axial direction. A lifting cylinder 13 is rotatably installed on the top of the moving column 11 through a third sealing component. An axial movable block 14 is installed on the side of the lifting cylinder 13. The top of the lifting cylinder 13 is connected to a connecting pipe 15. A movable chamber 42 connected to the lifting cylinder 13 is provided on 11, and exhaust holes 20 and flow holes 19 are respectively provided on the peripheral outer walls of the lifting cylinder 13 and the two hollow rods 16, wherein the lifting cylinder 13 is communicated with the movable chamber 42 through the exhaust hole 20, and the hollow rod 16 is communicated with the movable chamber 42 through the flow hole 19. An I-shaped ring 32 is sleeved on the upper part of the movable column 11, and an annular block 33 is rotatably sleeved on the I-shaped ring 32. Four fixed plates 34 are evenly spaced around the side of the annular block 33, and the fixed plates 34 are arranged along the radial direction of the annular block 33. Moving rods 35 are rotatably installed on the four fixed plates 34, and rectangular blocks 36 are fixedly installed on the four moving rods 35. Four fixed columns 37 are respectively installed on the bottom of the four rectangular blocks 36. The purification tank 4 is provided with a driving unit that makes the movable sleeve 10, the two hollow rods 16, and the four rectangular blocks 36 rotate around their own axes and makes the lifting plate 26 move up and down.

[0039] In this solution, while the movable sleeve 10 and the movable column 11 rotate, the movable column 11 can also move up and down, and the upward and downward movement of the movable column 11 drives the rectangular block 36 to move up and down.

[0040] Specifically, by rotating the movable sleeve 10 and the movable column 11 while causing the movable column 11 to move up and down, the hollow rod 16 can be moved up and down while performing a circular motion, and the air outlet 18 can be moved up and down while performing a circular motion, so that the steam can contact the furfural solution at different heights and different horizontal positions. By moving the rectangular block 36 up and down with the movable column 11, the crushing plate 38 can always be above the air outlet 18.

[0041] like Figure 1 、 Figure 3 and Figure 4As shown, the driving unit includes a protective box 7 installed on the top of the purification tank 4. The top of the protective box 7 is provided with an avoidance hole adapted to the lifting cylinder 13 and the movable block 14, so that the lifting cylinder 13 can move axially but cannot rotate. The lifting cylinder 13 is provided with a driven element that rotates the two hollow rods 16. The top of the protective box 7 is provided with a motor 23. The top of the purification tank 4 is rotatably provided with a movable rod 24 and a driven rod 30 through a fourth sealing assembly. The top of the movable rod 24 extends to the outside of the protective box 7 and is fixedly connected to the output shaft of the motor 23. Then, the outer fixed sleeve of the movable rod 24 is provided with a reciprocating threaded guide sleeve 25, the lifting plate 26 is threadedly connected to the reciprocating threaded guide sleeve 25, and the protective box 7 is provided with a guide element adapted to the lifting plate 26. There are three driven rods 30, and the three driven rods 30 and the movable rod 24 are arranged in a ring. The bottoms of the movable rod 24 and the three driven rods 30 are provided with rectangular grooves adapted to the rectangular block 36. The upper part of the rectangular block 36 is slidably inserted into the rectangular groove and fixedly connected thereto. The movable rod 24 is connected to the movable sleeve 10 and the three driven rods 30 through a transmission element.

[0042] In this solution, the protective box 7, motor 23, movable rod 24, reciprocating threaded guide sleeve 25, driven rod 30 and rectangular groove are arranged to facilitate the up and down movement of the lifting plate 26, and the rectangular block 36 can be raised and lowered while rotating.

[0043] Specifically, by moving the lifting plate 26 up and down, the movable column 11 can be driven to move up and down, thereby causing the position of the air outlet 18 to change continuously. By raising and lowering the rectangular block 36 while rotating it, the crushing plate 38 can be rotated at any height. At the same time, the provision of the protective box 7 can play a certain protective role, preventing the external environment from affecting the transmission of the internal devices.

[0044] like Figure 4 As shown, the guide element includes a guide rod 27 installed in the protection box 7, and the lifting plate 26 is slidably connected to the guide rod 27.

[0045] like Figure 4 As shown, the driven element includes a first bevel gear 21 installed at the bottom of the lifting cylinder 13, and a second bevel gear 22 is installed at the end of the two hollow rods 16 close to each other. The two second bevel gears 22 are engaged with the first bevel gear 21. An isolation box 39 is installed on the bottom inner wall of the movable cavity 42, and the top and both side outer walls of the isolation box 39 are respectively provided with isolation holes adapted to the lifting cylinder 13 and the two hollow rods 16.

[0046] In this solution, the first bevel gear 21, the second bevel gear 22 and the isolation box 39 are arranged to facilitate the hollow rod 16 to rotate while performing a circular motion.

[0047] Specifically, by making the hollow rod 16 rotate while moving in a circular motion, the air hole 18 can be made to rotate along the hollow rod 16 while moving in a circular motion, so that the steam contacts the furfural solution at different horizontal and vertical heights. At the same time, by setting the isolation box 39, the first bevel gear 21 and the second bevel gear 22 can be isolated to avoid contact with the steam.

[0048] like Figure 1 As shown, a sealing door 8 is hingedly mounted on the side of the protection box 7 .

[0049] In this solution, by providing the sealing door 8 , one side of the protection box 7 can be opened, thereby facilitating subsequent observation and maintenance of the components inside the protection box 7 .

[0050] like Figure 4 As shown, the transmission element includes a first circular gear 28 sleeved on the movable sleeve 10, a second circular gear 29 sleeved on the movable rod 24, the first circular gear 28 and the second circular gear 29 are meshed with each other, and the three driven rods 30 are each equipped with a third circular gear 31, and the three third circular gears 31 are all meshed with the first circular gear 28.

[0051] In this solution, the first circular gear 28 , the second circular gear 29 and the third circular gear 31 are provided to facilitate the rotation of the movable sleeve 10 and the driven rod 30 .

[0052] Specifically, the movable sleeve 10 rotates to rotate the movable column 11, thereby causing the air outlet 18 to move in a circular motion. The driven rod 30 rotates to rotate the crushing plate 38, thereby crushing the steam bubbles.

[0053] like Figure 4 As shown, the diameter of the first circular gear 28 is larger than the diameters of the second circular gear 29 and the third circular gear 31 .

[0054] In this solution, the rotation speed of the movable sleeve 10 can be made lower than the rotation speed of the rectangular block 36 by the diameter ratio of the first circular gear 28 , the second circular gear 29 and the third circular gear 31 .

[0055] Specifically, by avoiding the situation where the stirring speed is too fast and causes the liquid to be violently turbulent, thereby forming a large amount of foam or splashing droplets, the rotational crushing effect of the crushing plate 38 is ensured at the same time.

[0056] like Figure 5 As shown, a screen 41 is installed on each of the plurality of air outlet holes 18 .

[0057] In this solution, the screen 41 is provided to play a certain blocking role.

[0058] Specifically, the screen 41 blocks the furfural solution from entering the movable cylinder 17 .

[0059] The method for producing furfuryl alcohol using a high-gravity reactor comprises the following steps:

[0060] S1, the furfural solution after washing is charged into the purification tank 4 through the feed port 6, and the steam is discharged from the vent 18 to contact the furfural solution;

[0061] S2. When the steam contacts the furfural solution, the aeration assembly is driven to move the air outlet 18 up and down through the hollow rod 16 and the movable cylinder 17. At the same time, the hollow rod 16 is rotated. The rotation of the hollow rod 16 causes the air outlet 18 to move in a circular motion along the hollow rod 16, thereby allowing the steam to contact the furfural solution at different heights, horizontal and vertical positions.

[0062] S3, driving the aeration assembly to rotate the rectangular block 36, which in turn rotates the crushing plate 38, thereby cutting the bubbles generated when steam is added;

[0063] S4. When the azeotropic mixed gas formed by water vapor and furfural rises above the liquid surface of the solution, it will enter the condenser 3 for condensation. After condensation, it will be output to the transfer tank 2 for sedimentation. After sedimentation is completed, the furfural is first preheated, and then the purified furfural solution is output to the high-gravity reactor body 1 through a plunger pump. Then, hydrogen and catalyst are added, and the high-speed rotor and copper-based catalyst react efficiently with hydrogen to prepare furfural alcohol.

[0064] The working principle of this device is that before use, first connect the connecting pipe 15 to the steam generator, and then load the washed furfural solution into the purification tank 4 through the feed port 6. At this time, due to the obstruction of the screen 41, the furfural solution cannot flow into the movable cylinder 17 through the air outlet 18. After the furfural is loaded, start the steam generator, and the output of the steam generator will be transported to the lifting cylinder 13 through the connecting pipe 15. Then the steam is discharged into the movable chamber 42 through the exhaust hole 20 on the lifting cylinder 13. Then the steam in the movable chamber 42 will flow into the hollow rod 16 through the flow hole 19. At the same time, the steam in the hollow rod 16 will flow into the movable cylinder 17 and be ejected from multiple air outlets 18, so that the steam is in contact with the furfural solution.

[0065] When the steam contacts the furfural solution, the motor 23 is started, and the motor 23 rotates the movable rod 24. The rotation of the movable rod 24 rotates the reciprocating threaded guide sleeve 25, thereby causing the lifting plate 26 to move up and down. The up and down movement of the lifting plate 26 causes the movable column 11 to move up and down. The up and down movement of the movable column 11 causes the lifting cylinder 13 and the two hollow rods 16 to move up and down. The up and down movement of the two hollow rods 16 causes multiple movable cylinders 17 to move up and down. The up and down movement of the movable cylinder 17 causes multiple air outlets 18 to move up and down, thereby causing the steam to contact the furfural solution at different heights. At the same time, the rotation of the movable rod 24 causes the second circular gear 29 to rotate. The rotation of the second circular gear 29 causes the first circular gear 28 to rotate. The rotation of the first circular gear 28 causes the movable sleeve 10 to rotate. The rotation of the movable sleeve 10 causes the movable column 11 to rotate through the movable groove and the movable block 12. Rotation, the rotation of the moving column 11 will cause the hollow rod 16 to rotate in a circle, the circular rotation of the hollow rod 16 will cause the movable cylinder 17 to move in a circle, the circular movement of the movable cylinder 17 will cause multiple air outlet holes 18 to move in a circle, thereby causing the steam to contact the furfural solution at different horizontal positions. When the moving column 11 rotates, the lifting cylinder 13 will be relatively stationary under the action of the third sealing component and the movable block 14. At this time, the moving column 11 drives the hollow rod 16 to move in a circle, and the hollow rod 16 will also rotate. The rotation of the hollow rod 16 will cause the movable cylinder 17 to rotate, and the rotation of the movable cylinder 17 will cause the air outlet holes 18 to move in a circle along the hollow rod 16, thereby causing the steam to contact the furfural solution at different heights, levels and vertical positions, thereby expanding the mass transfer area, improving the purification efficiency, and avoiding local overheating that causes furfural decomposition or dead corners that cause furfural residue.

[0066] When the movable column 11 moves up and down, it will drive the I-shaped ring 32 to move up and down, the I-shaped ring 32 will move up and down, the annular block 33 will move up and down, the annular block 33 will move up and down, the fixed plate 34 will move up and down, the fixed plate 34 will move up and down, the movable rod 35 will move up and down, the movable rod 35 will move up and down, the rectangular block 36 will move up and down, the rectangular block 36 will move up and down, the fixed column 37 will move up and down, the fixed column 37 will move up and down, and the crushing plate 38 will move up and down, thereby avoiding affecting the rotation of the movable cylinder 17. At the same time, the movable rod 24 passes through the first circle When the gear 28 and the second circular gear 29 drive the movable sleeve 10 to rotate, the rotation of the first circular gear 28 will cause the third circular gear 31 to rotate, and the rotation of the third circular gear 31 will cause the driven rod 30 to rotate. The rotation of the movable rod 24 and the driven rod 30 will cause the rectangular block 36 to rotate through the rectangular groove. The rotation of the rectangular block 36 will cause the fixed column 37 to rotate. The rotation of the fixed column 37 will cause the crushing plate 38 to rotate. The rotation of the crushing plate 38 will cut the bubbles generated when steam is added, thereby refining the bubble size, increasing the gas-liquid contact area, effectively improving the purification efficiency, and enhancing the separation effect.

[0067] When the azeotropic mixed gas formed by water vapor and furfural rises above the liquid surface of the solution, it will be introduced into the condenser 3 through the outlet pipe 9 with a stable flow field for condensation. After condensation, it will be output to the transfer tank 2 for sedimentation.
