Description

Technical Field

[0001] This invention relates to the field of reactor technology, specifically to an impact jet stirred reactor for the synthesis of bio-based polyether polyols. Background Technology

[0002] The impact jet stirred reactor for the synthesis of bio-based polyether polyols is a specialized reaction device designed for the characteristics of bio-based raw materials. Its core technology replaces traditional mechanical stirring with the impact and shearing action of high-speed jets to achieve efficient mixing and reaction.

[0003] Existing technologies struggle to flexibly change the jet impact position and convergence point during use, making it difficult to solve the mixing dead zone problem under the high viscosity characteristics of bio-based raw materials and enhance the turbulence intensity in different regions. Furthermore, they are difficult to adapt to the nozzle shape requirements of different synthesis stages, thus hindering dynamic optimization of the flow field during the reaction process and improving the equipment's adaptability to various bio-based raw materials. Moreover, existing technologies struggle to dynamically adjust the intensity and direction of fluid swirl, making it difficult to enhance micro-mixing of materials and solve the problem of uneven mixing in traditional equipment. This further hinders the achievement of macro- and micro-dimensional control of the flow field, overcoming the limitations of uneven mixing and poor adaptability in traditional equipment, and ultimately reducing the synthesis efficiency and product uniformity of bio-based polyethers.

[0004] Finally, existing technologies have several drawbacks. Firstly, they struggle to rapidly alter the reactor flow field and adjust volume. Secondly, when using airbags for adjustment, it's difficult to precisely optimize the airbag morphology and enhance local shear and heat transfer, making it challenging to achieve macro- and micro-level control of the flow field. This makes it difficult to avoid the problems of scaling and rigid adjustment associated with traditional baffles, reducing reaction efficiency and product uniformity. Thirdly, existing technologies struggle to enhance internal reactor circulation and mixing through the combined use of agitators and impact jets, resulting in limited practicality. Furthermore, some equipment is difficult to adapt to different reaction scales, flexibly optimize the stirring range, and disperse airflow and refine bubbles, reducing gas-liquid mass transfer efficiency and ultimately hindering the stability of bio-based polyether polyol product quality.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The embodiments of this invention will now be described according to its overall structure.

[0030] Example 1:

[0031] Please see Figures 1-3 The present invention provides an impact jet stirred reactor for the synthesis of bio-based polyether polyols, comprising a reactor body 1, the top left end of the reactor body 1 being fixedly connected to the outer wall of the regulating mechanism 2, an air filling and pumping mechanism 3 being fixedly connected to the left end of the reactor body 1, and a stirring mechanism 4 being fixedly connected to the center of the top of the reactor body 1.

[0032] The regulating mechanism 2 includes a first mounting box 21. The top left end of the reactor body 1 is fixedly connected to the outer wall of the first mounting box 21. The bottom of the first mounting box 21 is slidably connected to the first electromagnetic block 22. The bottom of the first electromagnetic block 22 is magnetically attracted to the nozzle 23, and the back of the nozzle 23 is fixedly connected to the hose, which is connected to an external high-pressure pump.

[0033] A flow guiding mechanism 24 is fixedly connected to the upper outer side of the nozzle 23. A first motor 25 is fixedly connected to the upper inside of the first mounting box 21. A second turntable 26 is fixedly connected to the bottom output shaft of the first motor 25. The first motor 25 can easily drive the second turntable 26 to rotate.

[0034] The top of the second turntable 26 is rotatably connected to four sets of first rotating rods 27, and the bottom of the first rotating rods 27 is rotatably connected to a moving block 28. The outer wall of the moving block 28 is slidably connected to the limiting plate 29, and the first rotating rods 27 facilitate the movement of the moving block 28.

[0035] The outer wall of the limiting plate 29 is fixedly connected to the inner wall of the first mounting box 21, and the bottom of the moving block 28 is fixedly connected to the first electromagnetic block 22, which is electrically connected to the external current output device.

[0036] The first rotating rod 27 is V-shaped, and the limiting plate 29 is provided with limiting grooves around its perimeter to facilitate the limiting and sliding of the moving block 28. The first electromagnetic block 22 and the nozzle 23 are each provided with four sets.

[0037] The working principle of the impact jet stirred reactor for the synthesis of bio-based polyether polyols based on Example 1 is as follows:

[0038] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0039] Secondly, during the use of reactor body 1, four sets of nozzles 23 transport the reactants into reactor body 1 through an external high-pressure pump. The high-speed fluid jets ejected from the nozzles 23 collide head-on in the central area of ​​reactor body 1. At the point of impact, the kinetic energy of the fluid is converted into violent turbulence, forming a very small impact zone. In this zone, the materials are instantly and uniformly mixed at the molecular scale. The fluids after the collision disperse in all directions and move upward or downward along the wall of reactor body 1, forming a large-scale circulating flow field to ensure uniform material concentration and temperature throughout reactor body 1.

[0040] Third, when it is necessary to adjust the distance between the four sets of nozzles 23, the operator selects the required nozzle 23, and drives the first electromagnetic block 22 to work through an external current output device, so that the first electromagnetic block 22 magnetically attracts the nozzle 23, completing the installation and fixing of the nozzle 23, thereby adapting to the shape requirements of the nozzle 23 in different synthesis stages. Then, the first motor 25 is started, and the first motor 25 drives the second turntable 26 to rotate. The second turntable 26, through the rotational connection with the four sets of first rotating rods 27, drives the four sets of moving blocks 28 to move on the limiting plate 29, so that... The distance between the four sets of moving blocks 28 gradually shortens or increases. The four sets of moving blocks 28 drive the distance between the four sets of first electromagnetic blocks 22 to gradually shorten or increase. The four sets of first electromagnetic blocks 22 drive the distance between the four sets of nozzles 23 to gradually shorten or increase. This achieves the adjustment of the four sets of nozzles 23, flexibly changes the jet impact position and intersection point, solves the mixing dead zone problem under the high viscosity characteristics of bio-based raw materials, enhances the turbulence intensity in different areas, and, in conjunction with the change of nozzle shape, achieves dynamic optimization of the flow field during the reaction process, improving the adaptability of the equipment to various bio-based raw materials.

The second motor 32 drives the second rotating rod 33 to rotate, which in turn drives the first toothed plate 34 to rotate and mesh with the long gear 36, causing the long gear 36 to rotate. At this time, the third rotating rod 35 rotates synchronously, and the long gear 36 drives the second toothed plate 37 to move left or right. The second toothed plate 37 then drives the piston rod 38 to move left or right within the piston cylinder 39, thereby slowly inflating and evacuating the corrugated airbag 312. Slow inflation and deflation precisely optimize the shape of the wave-shaped airbag 312, enhancing local shear and heat transfer. Simultaneously, it achieves macro- and micro-level control of the flow field, avoiding the problems of scaling and rigid adjustment of traditional baffles, improving reaction efficiency and product uniformity. Furthermore, during the movement of the second toothed plate 37 to the left or right, the electric spring 315 is driven by an external power source, causing the second toothed plate 37 to synchronously drive the electric spring 315 to extend or contract. This generates a stress field around the electric spring 315, which affects the resistance value of the resistance strain gauge 316. The resistance strain element inside the resistance strain gauge 316 deforms under stress, allowing the operator to calculate the length change of the electric spring 315 by using the resistance value of the resistance strain gauge 316, thereby indirectly determining the amount of slow inflation and deflation of the wave-shaped airbag 312.

[0060] Example 4:

[0061] Please see Figures 7-8 The present invention provides an impact jet stirred reactor for the synthesis of bio-based polyether polyols. Compared with Embodiment 1, this embodiment further includes: a stirring mechanism 4, which includes a third motor 41. The third motor 41 is fixedly connected to the top center of the reactor body 1, and a fixed rod 42 is fixedly connected to the bottom output shaft of the third motor 41. The third motor 41 facilitates the rotation of the fixed rod 42.

[0062] The bottom of the fixed rod 42 is fixedly connected to the mounting shell 43. The bottom of the mounting shell 43 is provided with four sets of first sliding grooves 44. Eight sets of second electromagnetic blocks 45 are fixedly connected inside the first sliding grooves 44. The left and right ends of the mounting shell 43 are provided with second sliding grooves 46. The inner wall of the second sliding groove 46 is glued to the sealing airbag 47. The second electromagnetic blocks 45 facilitate the movement of the L-shaped plate 49.

[0063] The outer side of the sealing airbag 47 is sealed to the sealing plug 48. The second electromagnetic block 45 is magnetically attracted to the L-shaped plate 49. The outer side of the L-shaped plate 49 is provided with a tapered hole 410. The second electromagnetic block 45 is electrically connected to the external current output device. The sealing airbag 47 is in contact with the outer wall of the L-shaped plate 49. The L-shaped plate 49 is slidably connected in the first sliding groove 44.

[0064] In this embodiment:

[0065] When material needs to be stirred, the eight sets of second electromagnetic blocks 45 are driven to work in stages by an external current output device. This causes the L-shaped plate 49 to move to the left or right under the magnetic attraction of the eight sets of second electromagnetic blocks 45. After the movement is completed, the sealing airbag 47 is inflated by an external inflation device, so that the sealing airbag 47 and the L-shaped plate 49 are in full contact. The sealing airbag 47 is then sealed by the sealing plug 48 to ensure the internal sealing of the mounting shell 43. Then, the third motor 41 is started, which drives the fixed rod 42 to rotate. The fixed rod 42 drives the mounting shell 43 to rotate, and the mounting shell 43 drives the two sets of L-shaped plates 49 to rotate. Through the rotation of the mounting shell 43 and the L-shaped plates 49 and the synergy of the impact jet, the internal circulation mixing of the reactor body 1 is enhanced. Through the movement of the two sets of L-shaped plates 49 and the conical hole 410, different reaction scales are adapted and the stirring range is flexibly optimized. At the same time, the airflow is dispersed, the bubbles are refined, the gas-liquid mass transfer efficiency is improved, and the quality stability of the bio-based polyether polyol product is ensured.

[0066] This invention provides an improved impact jet stirred reactor for the synthesis of bio-based polyether polyols. An adjustment mechanism 2 is incorporated, which, by adjusting four sets of nozzles 23, flexibly changes the jet impact position and convergence point, solving the problem of mixing dead zones under the high viscosity characteristics of bio-based raw materials and enhancing turbulence intensity in different regions. Simultaneously, through coordination with the changing shape of the nozzles 23, dynamic optimization of the flow field during the reaction process is achieved, improving the equipment's adaptability to various bio-based raw materials. A flow guiding mechanism 24 is also included, which, through the angle adjustment of the guide plates 2415, dynamically adjusts the intensity and direction of fluid swirl, enhancing micro-mixing of materials and solving the problem of uneven mixing in traditional equipment. Furthermore, through coordination with the adjustment and replacement of the distance between the four sets of nozzles 23, macro- and micro-dimensional control of the flow field is achieved, overcoming the limitations of uneven mixing and poor adaptability in traditional equipment, and improving the synthesis efficiency and product uniformity of bio-based polyethers. A charging and evacuating mechanism 3 is set up to rapidly charge and evacuate the corrugated airbag 312 using an external vacuum pump, quickly changing the flow field and adjusting the volume of the reactor body 1. Then, the piston rod 38 moves left or right within the piston cylinder 39 to slowly charge and evacuate the corrugated airbag 312, precisely optimizing its shape, enhancing local shear and heat transfer, and achieving macro- and micro-level control of the flow field. This avoids the problems of scaling and rigid adjustment of traditional baffles, improving reaction efficiency and product uniformity. A stirring mechanism 4 is set up to enhance the internal circulation mixing of the reactor body 1 through the rotation of the mounting shell 43 and L-shaped plate 49 and the synergy of the impact jet. The movement of the two sets of L-shaped plates 49 and the conical holes 410 adapt to different reaction scales and flexibly optimize the stirring range. At the same time, it disperses the airflow, refines the bubbles, improves the gas-liquid mass transfer efficiency, and ensures the stable quality of the bio-based polyether polyol product.
