Description

Technical Field

[0001] The present invention relates to the technical field of chemical agent manufacturing, in particular to a phytosterol hydrogenation system and a hydrogenation method thereof. Background Art

[0002] Phytosterols are a type of steroidal components present in plant cells. They can lower blood cholesterol, improve symptoms related to benign prostatic hyperplasia, and have anti-aging effects in the human body. Phytosterol hydrogenation is a chemical process that saturates the unsaturated bonds in phytosterols through hydrogenation reactions, which can improve the chemical stability of phytosterols.

[0003] When performing the phytosterol hydrogenation reaction, a dedicated hydrogenation reactor is required, and temperature is an important parameter affecting the hydrogenation reaction rate. Higher temperatures can accelerate the reaction rate. In actual operation, the temperature is usually controlled between 100-250°C. However, when the existing reactor performs the phytosterol hydrogenation reaction on the phytosterols, the phytosterols and solvent accumulate at the bottom of the reactor under the action of gravity. When the phytosterols and the reaction solvent are heated, the temperature of the phytosterols and the reaction solvent in direct contact with the inner wall of the reactor will be significantly higher than that of the sterols away from the reactor. Even if the sterols inside the reactor are stirred, the stirring blades cannot directly contact the inner wall of the reactor and can only stir in a single direction, which cannot improve the heating uniformity of the phytosterols. As a result, the quality of the hydrogenation reaction is adversely affected by the heating uniformity of the phytosterols and the reaction solvent. Summary of the Invention

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 8 , the present invention provides a technical solution: A plant sterol hydrogenation system includes a reactor 13, a motor 14 is fixedly connected to the outer surface of the left end of the reactor 13, a drive rod 21 is fixedly connected to the right end of the output shaft of the motor 14, and a material distribution assembly is provided on the outer side of the drive rod 21; The material distribution assembly includes a pull rod 24 fixedly connected to the outer surface of the driving rod 21, and the pull rod 24 is fixedly connected to a fixed sleeve 23 at one end away from the driving rod 21. The fixed sleeve 23 is rotatably connected to the left and right ends of the inner surface of the reactor 13, and a baffle 26 is fixedly connected to the inner surface of the fixed sleeve 23. The lower side of the inner surface of the reactor 13 is fixedly connected to a thermal insulation pad 42, and the outer surface of the upper end of the thermal insulation pad 42 is fixedly connected to a heating plate 27, and the heating plate 27 is in rotational contact with the outer surface of the fixed sleeve 23.

[0021] The heating plate 27 is arc-shaped, and the number of the heating plates 27 is several groups and distributed in a linear array. The driving rod 21 extends to the outside of the reactor 13 at one end away from the motor 14 and is rotatably connected to the reactor 13. A material guide cavity 22 is opened on the inner side of the driving rod 21. The number of the pull rods 24 is several groups and is symmetrically distributed. The outer surface of the baffle 26 is arc-shaped and is equidistantly distributed on the inner wall of the fixed sleeve 23.

[0022] The outer surface of the right end of the reactor 13 is fixedly connected to a vacuum tube 16, the outer surface of the lower end of the reactor 13 is fixedly connected to a base 11, and a through groove 12 is opened through the outer surface of the base 11. The outer surface of the right end of the reactor 13 is fixedly connected to a discharge pipe 19, and the discharge pipe 19 is located on the lower side of the vacuum tube 16.

[0023] By adopting the above technical solution, when hydrogenating sterols, it is usually necessary to keep the sterols at an appropriate reaction temperature in order to increase the reaction speed. In order to keep the temperature of the sterols inside the reactor 13 consistent, a material equalization component is set. During operation, the base 11 supports the reactor 13. The fixed sleeve 23 inside the reactor 13 is used to place the reaction raw materials. Before the reaction raw materials are injected, the excess air inside the fixed sleeve 23 is extracted through the vacuum tube 16 to reduce the probability of oxidation reaction between the sterols and oxygen in the air. During the sterol hydrogenation reaction, the heating plate 27 generates heat and transfers it to the fixed sleeve 23. The heat is transferred to the reaction raw materials through the fixed sleeve 23, so that the temperature inside the fixed sleeve 23 is kept within an appropriate range. The output shaft of the motor 14 drives the drive rod 21 to rotate synchronously, and the drive rod 2 The fixed sleeve 23 is driven by the pull rod 24 to perform circular motion. Under the action of gravity, the sterol and reaction solvent (common reaction solvents include butanol, isopropanol, etc.) will always gather in the lower area inside the fixed sleeve 23. During the rotation process, the outer surface of the fixed sleeve 23 will rotate and contact with the heating plate 27, so that the fixed sleeve 23 can be evenly heated by the heating plate 27, which helps to improve the heating uniformity of the sterol. At the same time, during the rotation process, the internal baffles 26 of the fixed sleeve 23 can increase the friction between the fixed sleeve 23 and the sterol, so that the baffles 26 can disturb the sterol, thereby further improving the mixing uniformity of the sterol, butanol and catalyst, thereby effectively improving the quality of the sterol hydrogenation reaction. After the hydrogenation reaction is completed, the material is discharged to the outside of the reactor 13 through the discharge pipe 19.

[0024] Specifically, such as Figure 3 and Figure 4 As shown, a stirring assembly is provided on the outside of the driving rod 21, and the stirring assembly includes a rotating seat 25 fixedly connected to the outer surface of the driving rod 21, and a connecting plate 30 is fixedly connected to the outer surface of the rotating seat 25. The connecting plate 30 is fixedly connected to the end away from the rotating seat 25 with a flap 43, and the flap 43 is arc-shaped. The number of the connecting plates 30 and the flap 43 is several groups and distributed in a ring array.

[0025] By adopting the above technical solution, in order to further improve the mixing uniformity and heating uniformity between the sterols, reaction solvent and catalyst, a stirring assembly is provided. During operation, the driving rod 21 drives the connecting plate 30 to rotate synchronously through the rotating seat 25, and drives the flap 43 to perform circular motion inside the fixed sleeve 23 through the connecting plate 30. The rotation of the flap 43 can flip the sterols and reaction solvent inside the fixed sleeve 23, so that the sterols, reaction solvent and catalyst can be fully mixed and contacted, thereby increasing the reaction speed and further improving the quality of the sterol hydrogenation reaction.

[0026] Specifically, such as Figure 4 and Figure 7 As shown, an oscillation component is provided on the outside of the connecting plate 30, and the oscillation component includes a slide groove 35 opened on the outer surface of the connecting plate 30, and a slide rod 34 is slidably connected to the inside of the slide groove 35. The two ends of the slide rod 34 are respectively fixedly connected to the blocking wheels 36, and the blocking wheels 36 are symmetrically distributed on both sides of the flap 43.

[0027] By adopting the above technical solution, during the operation of the stirring component, in order to reduce the residue of the reaction raw materials on the surface of the flap 43 and the connecting plate 30, an oscillation component is set, and the slide groove 35 opened on the surface of the connecting plate 30 is used to guide and support the slide rod 34. When the driving rod 21 drives the connecting plate 30 to rotate to stir the sterol and the reaction solvent, the slide groove 35 on the surface of the connecting plate 30 can make the sterol and the reaction solvent flow irregularly, thereby further improving the mixing uniformity of the sterol and the reaction solvent. The blocking wheels 36 at both ends of the slide rod 34 can not only increase the counterweight of the slide rod 34, but also prevent the slide rod 34 from sliding When the connecting plate 30 is rotated to the upper side, the slide bar 34 and the stop wheel 36 will move toward the side of the rotating seat 25 under the action of gravity, and when the connecting plate 30 is rotated to the lower side of the driving rod 21, the slide bar 34 will slide toward the side of the flap 43, and the slide bar 34 will collide with the connecting plate 30 through the slot, thereby causing the connecting plate 30 and the flap 43 to vibrate to a certain extent, thereby accelerating the falling of sterols on the surfaces of the connecting plate 30 and the flap 43, helping to reduce the residual sterols on the surfaces of the connecting plate 30 and the flap 43, and thus effectively reducing the difficulty of cleaning the inside of the reactor 13.

[0028] Specifically, such as Figure 4 and Figure 6As shown, a feeding assembly is provided on the inner side of the driving rod 21, and the feeding assembly includes a feeding hole 28 opened on the outer surface of the driving rod 21, and the number of the feeding holes 28 is several groups and distributed in a ring array. The outer surface of the right end of the reactor 13 is fixedly connected to the receiving hopper 17, and the upper end of the receiving hopper 17 is open. The right end of the driving rod 21 passes through the inside of the receiving hopper 17, and the outer surface of the driving rod 21 is provided with a feeding trough 41 on the inner side of the receiving hopper 17. The number of the feeding troughs 41 is several groups and distributed in a ring array. The upper side of the outer surface of the reactor 13 is fixedly connected to the feeding pipe 15.

[0029] By adopting the above technical solution, sterols and reaction solvents are injected into the fixed sleeve 23 through the feeding pipe 15. During the sterol hydrogenation reaction, an appropriate amount of catalyst needs to be added to maintain the normal progress of the addition reaction. In order to improve the uniformity of catalyst feeding, a feeding assembly is set. During operation, the catalyst is injected into the receiving hopper 17. During the rotation of the driving rod 21, the catalyst will enter the guide cavity 22 through the feeding groove 41 on the surface of the driving rod 21. As the driving rod 21 continues to rotate, the catalyst will move inside the guide cavity 22, and then the catalyst will enter the fixed sleeve 23 through the feeding hole 28 on the surface of the driving rod 21. The sterol and reaction solvent are stirred along with the connecting plate 30 and the flap 43, so that the catalyst is evenly fed into the sterol and the reaction solvent, thereby improving the quality of the sterol hydrogenation reaction to a certain extent.

[0030] Specifically, such as Figure 4 、 Figure 6 and Figure 7 As shown, a hydrogenation assembly is provided inside the material guide cavity 22, and the hydrogenation assembly includes a sealing plate 29 fixedly connected to the inner surface of the material guide cavity 22, and an air guide pipe 18 is fixedly connected to the outer surface of the sealing plate 29. The air guide pipe 18 is located inside the material guide cavity 22, and the right end of the air guide pipe 18 passes through the outside of the material receiving hopper 17 and is rotatably connected to the material receiving hopper 17. A connecting pipe 31 is embedded in the inner side of the rotating seat 25.

[0031] An overflow groove 32 is embedded on the inner side of the connecting plate 30, one end of the connecting pipe 31 is fixedly connected to the inside of the air guide pipe 18 and the other end is connected to the inside of the overflow groove 32, and a nozzle 33 is embedded and fixedly connected on the inner side of the slide groove 35. The nozzle 33 is connected to the inside of the overflow groove 32, and the number of the nozzles 33 is several groups and distributed in a parallel array.

[0032] By adopting the above technical solution, when the sterols and the reaction solvent are stirred, hydrogen needs to be continuously injected into the reactor 13. For this purpose, a hydrogenation assembly is provided. During operation, hydrogen is injected into the air duct 18. The driving rod 21 fixes and supports the air duct 18 through the sealing plate 29. The hydrogen is then transported to the interior of the connecting pipe 31 through the air duct 18. The hydrogen is then transported to the nozzle 33 through the connecting pipe 31 and the overflow groove 32, and is sprayed into the interior of the sterols and the reaction solvent through the nozzle 33 at a certain pressure. Through the continuous injection of hydrogen, under the action of the catalyst, the hydrogen reacts with the unsaturated bonds in the sterols to improve the chemical stability of the sterols during storage and transportation.

[0033] Specifically, such as Figure 5 and Figure 8 As shown, a temperature control component is provided between the fixed sleeve 23 and the reactor 13. The temperature control component includes a through hole 20 opened on the outer surface of the reactor 13. The through hole 20 penetrates to the inner side of the reactor 13. The inner surface of the reactor 13 is slidably connected with a movable plate 40. The movable plate 40 is arc-shaped and is in sliding contact with the inner wall of the reactor 13.

[0034] A fixing plate 1 37 is fixedly connected to the outer surface of the lower end of the heating plate 27, and a fixing plate 2 39 is fixedly connected to the outer surface of the movable plate 40 away from the through hole 20. A capsule 38 is fixedly connected between the fixing plates 1 37 and 2 39, and the capsule 38 is filled with thermal expansion gas.

[0035] By adopting the above technical solution, during the sterol hydrogenation reaction, a suitable temperature can effectively increase the reaction speed. For this purpose, a temperature control component is set. The movable plate 40 is used to seal the through hole 20. When the temperature inside the fixed sleeve 23 rises, the heat will be transferred to the capsule 38 through the heating plate 27 and the fixed plate 1 37. At this time, the gas inside the capsule 38 will expand due to the heat, thereby gradually increasing the volume of the capsule 38. The capsule 38 will push the fixed plate 2 39, and the movable plate 40 will be driven by the fixed plate 2 39 to move along the inside of the reactor 13. As the movable plate 40 gradually moves, the movable plate 40 will be out of contact with the through hole 20, thereby opening the through hole 20, so that external air can enter between the fixed sleeve 23 and the reactor 13 through the through hole 20, so that the interior of the reactor 13 can be ventilated and heat-dissipated by the flow of air, so that the internal temperature of the reactor 13 can be maintained within an appropriate range, thereby ensuring the quality of the sterol hydrogenation reaction. Gate valves for controlling on and off are provided inside the feeding pipe 15 and the discharging pipe 18, so as to ensure the sealing of the interior of the reactor 13.

[0036] A hydrogenation method applicable to a phytosterol hydrogenation system comprises the following steps: S1: injecting sterol and reaction solvent into the fixed sleeve 23 through the feeding pipe 15, and evenly adding the catalyst into the sterol and reaction solvent through the feeding component; S2: The hydrogen is then transported to the interior of the connecting pipe 31 through the gas guide pipe 18 and ejected into the interior of the sterol and the reaction solvent through the nozzle 33 at a certain pressure; S3: The driving rod 21 drives the connecting plate 30 to rotate synchronously through the rotating seat 25, and the sterol and reaction solvent inside the fixed sleeve 23 can be flipped by the rotation of the flip plate 43; S4: The sliding rod 34 collides with the connecting plate 30 through the notch, causing the connecting plate 30 and the flap 43 to vibrate to a certain extent, thereby accelerating the falling of the sterol on the surface of the connecting plate 30 and the flap 43; S5: The driving rod 21 drives the fixing sleeve 23 to perform circular motion through the pull rod 24, so that the fixing sleeve 23 can be evenly heated by the heating plate 27; S6: The through hole 20 is opened so that external air can enter between the fixing sleeve 23 and the reactor 13 through the through hole 20 , thereby ventilating and dissipating heat inside the reactor 13 through the flow of air.
