Description

Technical Field

[0001] This invention belongs to the field of reactor technology, and particularly relates to a supergravity stator-rotor reactor. Background Technology

[0002] In chemical, environmental protection, and other fields, the purification of industrial gases through dehydration, desulfurization, and ammonia removal is a crucial unit operation. Traditional purification equipment, such as packed towers and plate towers, relies on interfacial contact under gravity for mass transfer, which has inherent drawbacks such as large equipment size, limited mass transfer efficiency, and large footprint. To overcome these limitations, hypergravity technology has emerged. This technology generates strong centrifugal force (simulating a hypergravity environment) through a rotating packed bed, tearing the liquid into micron- to nanometer-sized droplets, filaments, and films. This significantly expands the gas-liquid contact area and enhances the interfacial mass transfer process, thus enabling the reduction of packed towers, which can reach tens of meters in height, into a compact hypergravity reactor.

[0003] Existing hypergravity reactors typically employ a multi-layered concentric ring structure driven by a single main shaft. While each ring shares the same angular velocity, their linear velocities increase progressively from the inside out. This results in an uneven distribution of shear force and mass transfer intensity across the rotor surface. The outer ring region, due to its high linear velocity, becomes a highly efficient "mass transfer hotspot," while the inner ring region, with its low linear velocity, becomes a relatively inefficient "mass transfer dead zone." This inherent linear velocity gradient prevents the reactor's overall mass transfer efficiency from reaching its ideal state, limiting further performance improvements.

[0004] To address these issues, we propose a centrifugal stator-rotor reactor. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the overall mass transfer efficiency of the reactor fails to reach the ideal state due to the multi-layer concentric ring linear velocity gradient in the prior art, and to propose a supergravity stator-rotor reactor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A supergravity stator-rotor reactor includes a shell and a drive motor, and also includes a stator-rotor assembly disposed inside the shell; The stator-rotor assembly includes an upper end cover, a lower end cover, a stator component, and a rotor component; The stator component is formed by fixing multiple turbulence units distributed along the circumferential direction between the upper end cover and the lower end cover to form a multi-layer stator concentric ring; The rotor component includes multiple concentric rotor rings arranged concentrically from the inside to the outside. Multiple evenly distributed through holes are opened on the concentric rotor rings. The multiple concentric rotor rings and the multiple concentric stator rings are arranged alternately and stacked. The innermost concentric ring of the rotor is coaxially fixedly mounted with a rotating shaft extending out of the outer shell, and the rotating shaft is connected to the drive motor through a transmission mechanism; The two adjacent layers of the concentric rotor rings are connected by a gear reversing transmission mechanism, which drives the two adjacent layers of the concentric rotor rings to rotate in opposite directions with a predetermined speed difference.

[0007] Preferably, the gear reversing transmission mechanism includes a transition gear rotatably mounted on the turbulence unit, and an inner gear ring and an outer gear ring respectively fixed on the inner and outer sides of the rotor concentric ring; The transition gear meshes simultaneously with the adjacent inner gear ring on the outer side and the adjacent outer gear ring on the inner side.

[0008] Preferably, the upper end cover has a liquid inlet at its center, and the liquid inlet is connected to a liquid disperser that extends into the center of the innermost concentric ring of the rotor; the lower part of the side wall of the outer shell has a liquid outlet. The side wall of the outer shell is provided with a gas inlet, and the center of the upper cover is provided with a gas outlet. The gas outlet is configured as an annular jacket structure surrounding the liquid inlet. The overall flow paths of the liquid and gas constitute countercurrent contact.

[0009] Preferably, the turbulence unit is connected to the upper end cover and the lower end cover by bolt fastening.

[0010] Preferably, the transmission mechanism is a belt drive mechanism, including a double-rail pulley installed on the rotating shaft and the output end of the drive motor, and the two double-rail pulleys are connected by belt drive.

[0011] Preferably, the upper end cover and the lower end cover are provided with a plurality of positioning ring grooves adapted to the concentric ring of the rotor on the opposite side. The bottom of the positioning ring groove is a trapezoidal structure. The two ends of the concentric ring of the rotor are adapted to the positioning ring groove. A plurality of balls are provided on the bottom inclined surface of the positioning ring groove.

[0012] In summary, the technical effects and advantages of this utility model are as follows: This supergravity stator-rotor reactor, through the transition gear set on the stator turbulence unit, drives the concentric rings of the rotors in adjacent layers to rotate in opposite directions. At the same time, due to the change in radius, the rotational speed of the outer concentric rings of the rotor decreases accordingly as the radius increases, so that the linear velocity of the outer edge of each layer of concentric rings of the rotor remains close. This completely changes the uneven mass transfer situation of the traditional equipment where the inner ring is inefficient and the outer ring is efficient. It makes the entire rotor component area from the inside to the outside an effective mass transfer area, eliminates the "mass transfer dead zone", and achieves a uniform distribution of mass transfer intensity throughout the entire area, thereby significantly improving the overall volumetric mass transfer efficiency of the equipment.

[0013] The concentric rings of the rotors in adjacent layers rotate in opposite directions, so that the fluid between them is not only subjected to the shearing action between the rotor and the stator, but also to the double shearing effect from the two concentric rings of the rotors rotating in opposite directions. This generates a shear rate and turbulence intensity higher than that of devices rotating in the same direction, which can disperse the liquid into finer particles and greatly accelerate the surface renewal rate of droplets and liquid films. This creates the most favorable kinetic conditions for gas-liquid mass transfer and further enhances the mass transfer process. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] Reference Figure 1-5 A supergravity stator-rotor reactor includes a shell 1, a drive motor 2, and a stator-rotor assembly disposed inside the shell 1. The shell 1 provides a pressure-bearing sealed space for the entire device, and the drive motor 2 is fixedly installed on the side of the shell 1 as the power source for the entire rotor system.

[0019] The stator-rotor assembly includes an upper end cover 3, a lower end cover 4, a stator component, and a rotor component. The upper end cover 3 and the lower end cover 4 are fastened to the outer casing 1 by bolts, forming the mounting frame of the assembly.

[0020] The stator component consists of multiple circumferentially distributed turbulence units 5 fixedly installed between the upper end cover 3 and the lower end cover 4 to form a multi-layer stator concentric ring. The turbulence units 5 are connected to the upper end cover 3 and the lower end cover 4 by bolt fastening. The bolt connection method makes the turbulence units 5 easy to disassemble and replace, giving the equipment a high degree of modularity and maintenance convenience. Users can flexibly select different types or materials of turbulence units 5 according to different processing media or process requirements.

[0021] The rotor component includes multiple concentric rotor rings 6 arranged concentrically from the inside to the outside. Multiple evenly distributed through holes 61 are opened on the rotor concentric rings 6. The multiple concentric rotor rings 6 and the multiple concentric stator rings are alternately stacked to form multiple series-connected supergravity mass transfer units.

[0022] Reference Figure 2-3 The upper end cover 3 has a liquid inlet 31 at its center, and the liquid inlet 31 is connected to a liquid disperser 9 that extends into the center of the innermost concentric ring 6 of the rotor; the lower part of the side wall of the outer shell 1 has a liquid outlet 11; the side wall of the outer shell 1 has a gas inlet 12, and the upper end cover 3 has a gas outlet 32 ​​at its center. The gas outlet 32 ​​is set as an annular jacket structure surrounding the liquid inlet 31 to guide the process medium in and out. The overall flow path of the liquid and the gas forms a countercurrent contact.

[0023] Taking the gas-liquid reaction system as an example, the liquid is sprayed onto the first layer of rotor concentric rings 6 through the liquid disperser 9. It is cut and dispersed by the high-speed rotating elements to form tiny droplets, which improves its surface renewal rate. When these droplets fall onto the stator concentric ring elements, the liquid is redistributed and enters the second layer of rotor concentric rings 6 elements, where it is disturbed and dispersed again, and continues to enter the second layer of stator concentric rings for redistribution, and so on. During this process, the gas enters the stator-rotor assembly through the outer edge inlet, and also goes through the rotor layer-stator layer-rotor layer, which gives it a large opportunity to have surface contact with the liquid, thus improving the mass transfer effect.

[0024] The innermost rotor concentric ring 6 is coaxially fixedly mounted with a rotating shaft 7 extending out of the outer shell 1. The rotating shaft 7 is connected to the drive motor 2 through a transmission mechanism.

[0025] Reference Figure 2-4 The transmission mechanism is a belt drive mechanism 10, which includes a double-rail pulley installed on the rotating shaft 7 and the output end of the drive motor 2. The two double-rail pulleys are connected by belt drive, and the driving power is provided by the drive motor 2, which provides rotational power to the rotating shaft 7.

[0026] The two adjacent concentric rings 6 are connected by a gear reversing transmission mechanism 8, which drives the two adjacent concentric rings 6 to rotate in opposite directions with a predetermined speed difference.

[0027] Reference Figure 2-4 The gear reversing transmission mechanism 8 includes a transition gear 81 rotatably mounted on the turbulence unit 5, and an inner toothed ring 82 and an outer toothed ring 83 respectively fixed on the inner and outer sides of the rotor concentric ring 6; the transition gear 81 meshes with the adjacent inner toothed ring 82 on the outer side and the adjacent outer toothed ring 83 on the inner side.

[0028] When the innermost rotor ring is driven to rotate by the shaft 7, the power is transmitted outward sequentially through the gear mechanism. Due to the meshing of the transition gear 81, the rotation directions of the concentric rings 6 of the adjacent rotor layers are always opposite. The transmission ratio can be controlled by the tooth ratio of the inner tooth ring 82 and the outer tooth ring 83 in the concentric rings 6 of the adjacent rotor layers, so that the rotational speed of the outer rotor concentric ring 6 decreases step by step. The design principle is to ensure that the linear velocity of the outer edge of each rotor concentric ring 6 is approximately equal, which solves the problem of uneven mass transfer intensity caused by the increase of linear velocity from the inside to the outside in traditional supergravity machines. This makes the shear force and mass transfer process evenly distributed throughout the rotor area, eliminates the "mass transfer dead zone" of the inner ring, and thus improves the overall mass transfer efficiency. The huge relative velocity generated by the opposite rotation of the concentric rings 6 of the adjacent rotors further creates excellent fluid shear and surface renewal conditions.

[0029] Reference Figure 5 To ensure stable, low-friction high-speed rotation of the rotor components, multiple positioning ring grooves 13 adapted to the rotor concentric rings 6 are provided on the opposite side of the upper end cover 3 and the lower end cover 4. The bottom of the positioning ring groove 13 has a trapezoidal structure. The two ends of the rotor concentric rings 6 are adapted to the positioning ring grooves 13, and multiple balls 14 are provided on the bottom inclined surface of the positioning ring grooves 13. The rotor concentric rings 6 are pressed against the balls 14, which transforms the traditional sliding friction into rolling friction, greatly reducing the starting torque and running resistance. At the same time, it ensures the precise alignment and stable operation of each layer of rotor concentric rings 6, effectively suppressing vibration at high speeds.

[0030] Working principle: After preparation and confirmation of normal equipment operation, materials can be fed into the reactor for process operation. Start the drive motor 2, which drives the rotating shaft 7 and the innermost concentric rotor ring 6 to rotate at a set speed via the belt transmission mechanism 10. Power is then transmitted outwards step by step through the gear reversing transmission mechanism 8, driving the concentric rotor rings 6 to rotate. Adjacent concentric rotor rings 6 rotate in opposite directions, and the outermost rotation speed decreases step by step according to the design ratio to ensure that the linear velocity of the outer edges of each ring is basically consistent. Once the rotation speed stabilizes, open the process gas pipeline, allowing gas to enter the reactor tangentially from the gas inlet 12 on the side wall of the outer shell 1. Under pressure, the gas flows inwards from the outer edge of the reactor, passing sequentially through the through holes 61 on the high-speed rotating concentric rotor rings 6 and the gaps between the stationary turbulence units 5.

[0031] After the gas flow is established, the absorbent pipeline is opened. The liquid is pumped in through the liquid inlet 31 at the center of the upper end cover 3, and after initial distribution by the liquid disperser 9, it enters the innermost high-speed rotating rotor concentric ring 6 region. The liquid is immediately captured by the rotor concentric ring 6 and, under the action of huge centrifugal force, is thrown onto the surface of the rotor concentric ring 6, where it is violently sheared and broken into extremely fine droplets, liquid filaments, and liquid films. The dispersed liquid is thrown onto the outer turbulence unit 5 for redistribution and aggregation, and then captured again by the next layer of counter-rotating rotor concentric ring 6 for even more violent dispersion. In this process, the liquid is transported outward in stages.

[0032] Meanwhile, the process gas flowing from the outside in, and the highly dispersed liquid flowing counter-currently, come into full contact in the gaps between each layer of stator concentric rings and rotor concentric rings 6. Because the liquid is dispersed into extremely small scales and has a very rapid surface renewal rate, while the gas flow is highly turbulent due to the high-speed shearing of the rotor, the mass transfer area between the two phases is enormous, greatly enhancing the mass transfer efficiency. The purified gas eventually converges in the central area of ​​the equipment and is discharged through the annular jacketed gas outlet 32 ​​surrounding the liquid inlet 31. The liquid that has completed the absorption process is then completely thrown to the outermost cavity of the outer shell 1 by centrifugal force, and finally flows out from the lower liquid outlet 11.
