It is a breakthrough technology that uses the centrifugal force field generated by rotor rotation to simulate hypergravity to enhance mass transfer and multiphase flow reaction processes. The core of this technology is the hypergravity rotating bed. Compared with traditional chemical technologies, it has advantages such as high transfer efficiency, small equipment size, small footprint, low energy consumption, easy operation and maintenance, safety, and wide applicability.

[0003] Chinese Patent 200710157094.3 discloses a concentric ring counter-current high-gravity rotary bed, whose rotor includes a concentric sieve-hole moving ring, which is composed of a group of concentric rotating rings with sieve holes of different diameters. This rotary bed belongs to the plate rotor rotary bed category and has the advantages of simple structure and low manufacturing cost. However, the mass transfer efficiency of this rotary bed is not high, which limits its industrial application, and there is a problem of liquid residue at the bottom. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a supergravity bed. The supergravity bed ensures full contact and collision between gas and liquid within the channel, significantly improving mass transfer efficiency. At the same time, it also uses gravity through a drainage component to facilitate the smooth flow of liquid to the drainage pipe, preventing stagnation and accumulation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a supergravity bed, comprising a shell, an air outlet pipe and a liquid inlet pipe at the upper end of the shell, the liquid inlet pipe passing through the side wall of the air outlet pipe and disposed inside the air outlet pipe, an air inlet pipe on the side wall of the shell, a drain assembly at the bottom of the shell, a boss forming an upward protrusion at the center of the bottom of the shell, a rotating rod passing through the center of the boss, and a rotor connected to the end of the rotating rod that penetrates into the shell, gas and liquid entering the rotor through the air inlet pipe and the liquid inlet pipe respectively, moving multiple times and finally being discharged from the drain assembly and the air outlet pipe.

[0006] Furthermore, the rotor includes an upper plate and a lower plate. The upper plate is provided with several first concentric rings of different diameters, and the lower plate is provided with several second concentric rings of different diameters. The first and second concentric rings are provided with multiple through holes, and a gap is left between adjacent second concentric rings to accommodate the first concentric rings. The first and second concentric rings are nested together and arranged in an alternating manner to form a channel for gas-liquid flow.

[0007] Furthermore, both the first and second concentric circles are provided with multiple vertical radial mass transfer plates, each with multiple through holes. The mass transfer plates in the first concentric circle are circumferentially distributed on the outer side of the first concentric circle, and the mass transfer plates in the second concentric circle are circumferentially distributed on the inner side of the second concentric circle. The mass transfer plates in the first and second concentric circles are arranged alternately.

[0008] Furthermore, the concentric ring is provided with a vertical slot for the vertical clip of the mass transfer plate to be inserted. The bottom of the vertical slot is provided with a threaded hole, and the vertical clip is provided with an insertion hole corresponding to the threaded hole. The threaded rod is threaded through the end of the threaded hole and inserted into the insertion hole to realize the connection between the mass transfer plate and the concentric ring.

[0009] Furthermore, the lower plate is connected to the rotating rod, and there is a vertical distance between the upper plate and the lower plate. The upper and lower plates are connected by a screw. The vertical distance is greater than the height of the concentric rings. The upper plate has a hole in the middle, through which the air pipe and liquid inlet pipe pass.

[0010] Furthermore, the sidewall of the upper plate hole extends upward into the intake pipe and is provided with a dynamic seal between it and the inner wall of the intake pipe.

[0011] Furthermore, the lower plate is connected to the rotating rod, and there is a vertical distance between the upper plate and the lower plate, which is greater than the height of the concentric rings. The upper plate is connected to the housing by a screw, and a hole is provided in the middle of the upper plate, through which the air pipe and the liquid inlet pipe pass.

[0012] Furthermore, the sidewall of the upper plate hole extends upward into the intake pipe and a sealing ring is provided between it and the inner wall of the intake pipe.

[0013] Furthermore, the drainage component includes a drainage channel and a drainage pipe connected to the drainage channel. The drainage channel is generally annular and has a V-shaped cross-section. The drainage channel extends continuously at an incline along a preset drainage direction. The drainage end is connected to the inlet port of the drainage pipe, so that the fluid in the drainage channel flows along the drainage channel to the drainage pipe.

[0014] Furthermore, the liquid inlet pipe end is provided with a liquid distributor, the liquid distributor includes a liquid collection tank, a plurality of diversion tanks are evenly distributed around the liquid collection tank, the side wall of the liquid collection tank is provided with a diversion port for the diversion tank, the diversion tank is provided with a liquid outlet, and a disc extends circumferentially from the bottom of the diversion tank, the disc is provided with a guide plate for the liquid outlet.

[0015] Beneficial effects: 1. This application uses concentric rings nested and interwoven on the upper and lower plates, and the mass transfer plates are also staggered and have through holes, which greatly increases the gas-liquid contact area. The liquid is evenly dispersed by the distributor and forms a thin liquid film under the action of centrifugal force, allowing the gas to pass through efficiently and reducing mass transfer resistance. The connection between the mass transfer plates and the concentric rings is stable, ensuring that the gas and liquid fully contact and collide in the channel, which greatly improves the mass transfer efficiency.

[0016] 2. This application, through the setting of the drainage component, can effectively collect liquid and reduce residue. The tank is continuously tilted along the preset direction, and gravity helps the liquid to flow smoothly to the drainage pipe, avoiding stagnation and accumulation. The end of the drainage is precisely connected to the drainage pipe to ensure that all liquid is discharged and prevent liquid accumulation from corroding the equipment. Attached Figure Description

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] For reference Figures 1-3As shown, this application provides an embodiment of a supergravity bed, including a shell 1. The shell 1 includes a main shell with an upper opening. A cover is provided at the opening. The cover and the main shell are fastened together by bolts to form the shell 1. An air outlet pipe 2 and a liquid inlet pipe 3 are provided on the cover. The liquid inlet pipe 3 passes through the side wall of the air outlet pipe 2 and is disposed inside the air outlet pipe 2, and is located on the same axis. An air inlet pipe 16 is provided on the side wall of the main shell, and a liquid drainage assembly 4 is provided at the bottom of the main shell. The liquid drainage assembly 4 includes a drainage channel 41 and a liquid drainage pipe 42 connected to the drainage channel 41. The liquid drainage pipe 42 is located away from the air inlet pipe 16. The drainage channel 41 is generally annular and has a V-shaped cross-section. The drainage channel 41 extends continuously at an inclination along the preset drainage direction. The drainage end is connected to the liquid inlet of the liquid drainage pipe 42, so that the fluid in the drainage channel 41 is drained along the drainage channel 41 to the liquid drainage pipe 42. After the mass transfer is completed, the fluid is thrown off and falls into the shell 1 and drained through the drainage channel 41 to the liquid drainage pipe 42, preventing the problem of accumulation at the bottom of the shell 1. A boss 5 is formed by an upward protrusion at the bottom center of the shell 1. A rotating rod 6 is inserted through the center of the boss 5. A motor is installed on the rotating rod 6, which drives the rotating rod 6 to rotate. The end of the rotating rod 6, which extends into the shell 1, is connected to a rotor 7. The motor drives the rotating rod 6 to rotate, and synchronously drives the rotor 7 to rotate. Gas and liquid enter the rotor 7 from the inlet pipe 16 and the liquid inlet pipe 3, respectively, and undergo multiple high-speed movements before finally being discharged from the outlet pipe 42 and the outlet pipe 2. Specifically, gas enters the shell 1 from the gas inlet pipe. Driven by the rotating rotor 7, the gas enters the rotor 7 tangentially, contacts the concentric rings, and moves circumferentially. Under the action of pressure difference, the gas flows from the outside to the inside cavity along the channel formed between the concentric rings, and finally is discharged from the outlet pipe 2. Liquid enters the inner cavity of the rotor 7 from the liquid inlet pipe 3. Under the action of centrifugal force, it is thrown to all sides, flows from the inner cavity of the rotor 7 to the outside, and finally leaves the rotor 7, converging in the shell 1 and being discharged through the drain groove 41 and the drain pipe 42. The liquid flows inside the rotating rotor 7 and undergoes multiple dispersion and aggregation processes and acceleration processes. Under the action of centrifugal force, the liquid moves from the center of the lower plate 72 to the innermost second concentric ring 74. It is then accelerated and thrown off the upper plate 71 as fine droplets through the through hole 9 of the second concentric ring 74. On the upper plate 71, it is collided, sheared, and splashed. The above steps are repeated until it is thrown off the rotor 7.

[0020] For reference Figure 1As shown, the rotor 7 includes an upper plate 71 and a lower plate 72. The upper plate 71 has several first concentric rings 73 with different diameters, and the lower plate 72 has several second concentric rings 74 with different diameters. Multiple through holes 9 are provided on the first and second concentric rings 73 and 74. A gap is left between adjacent second concentric rings 74 to accommodate the first concentric rings 73. The first and second concentric rings 73 and 74 are nested together and arranged alternately to form channels for supplying gas and liquid fluids. The lower plate 72 is connected to the rotating rod 6. The upper plate 71 and lower plate 72 have a vertical distance between them and are connected by a screw. The vertical distance is greater than the height of the concentric rings. The first and second concentric rings 73 and 74 are at a uniform height, enabling the upper plate 71 and lower plate 72 to rotate synchronously. A hole is provided in the middle of the upper plate 71, through which the gas outlet pipe 2 and the liquid inlet pipe 3 extend, ensuring that gas is discharged from the gas outlet pipe 2 and liquid enters the rotor 7 from the liquid inlet pipe 3. The upper plate 71 has its sidewall extending upwards into the intake pipe 16 and is provided with a dynamic seal 13 between itself and the inner wall of the intake pipe 16. The dynamic seal 13 includes a packing seal, a mechanical seal, or an oil seal, all of which are existing technologies. The specific structure adopted in this application is that an elastic rubber sealing ring is fitted on the outer wall of the extension section of the upper plate 71, which fits tightly against the inner wall of the intake pipe 16 to form the first seal. An annular retaining ring is provided on the outside of the sealing ring, and a small air vent groove is opened on the retaining ring. A small amount of airflow in the groove forms a pressure barrier to prevent gas leakage and also reduces the friction and heat generation of the sealing ring. Other dynamic seal 13 structures are applicable as long as they can adapt to the structure of this application and are not limited to the above structures.

[0021] For reference Figure 2 As shown, in order to ensure that the liquid in the inlet pipe 3 can be evenly distributed on the rotor 7, a liquid distributor 15 is provided at the end of the inlet pipe 3. The liquid distributor 15 includes a collection tank 151, and multiple distribution tanks 152 are evenly distributed around the collection tank 151. The side wall of the collection tank 151 is provided with a distribution port 153 for the distribution tank 152. The distribution tank 152 is provided with an outlet 154. A disc 155 extends circumferentially to the bottom of the distribution tank. A guide plate 156 is provided on the disc 155 corresponding to the outlet 154. The liquid enters from the inlet pipe 3 and first enters the collection tank 151. Then it is discharged into the distribution tank 152 through the distribution port 153 at a uniform height. After the liquid reaches a certain height in the distribution tank 152, it flows from the outlet 154 along the direction of the guide plate 156 to the rotor 7, thereby achieving circumferential uniform liquid discharge and improving the mass transfer quality.

[0022] For reference Figures 4-7As shown, this application also provides a second embodiment, which is basically the same as the first embodiment, except that: both the first concentric ring 73 and the second concentric ring 74 are provided with a plurality of vertically radial mass transfer plates 8, and the mass transfer plates 8 are provided with a plurality of through holes 9. The mass transfer plates 8 located in the first concentric ring 73 are circumferentially distributed on the outside of the first concentric ring 73, and the mass transfer plates 8 located in the second concentric ring 74 are circumferentially distributed on the inside of the second concentric ring 74. The mass transfer plates 8 located in the first concentric ring 73 and the mass transfer plates 8 located in the second concentric ring 74 are arranged alternately.

[0023] The concentric ring is provided with a vertical slot 10, into which the vertical clip 11 of the mass transfer plate 8 is inserted. The bottom of the vertical slot 10 is provided with a threaded hole 101, and the vertical clip 11 is provided with an insertion hole 110 corresponding to the threaded hole 101. The threaded rod is threaded through the threaded hole 101 and the end is inserted into the insertion hole 110 to realize the connection between the mass transfer plate 8 and the concentric ring.

[0024] Specifically, such as Figures 4-7As shown, in order to further intensify the turbulence of the gas during the circumferential and radial flow process, thereby increasing the gas-phase mass transfer coefficient and significantly increasing the gas-liquid contact area, the mass transfer efficiency is improved. Furthermore, the increased gas flow area reduces the internal gas flow resistance of the rotor 7. Multiple vertically radial mass transfer plates 8 are provided on both the first concentric ring 73 and the second concentric ring 74. Each mass transfer plate 8 has multiple through holes 9. Some of the mass transfer plates 8 are distributed on the outer side of the first concentric ring 73, and some are distributed on the inner side of the second concentric ring 74. The mass transfer plates 8 in the first concentric ring 73 and the mass transfer plates 8 in the second concentric ring 74 are arranged alternately. Through the arrangement of the mass transfer plates 8, the liquid, under the action of centrifugal force, climbs from the center of the lower plate 72 to the innermost second concentric ring 74. It then accelerates and is thrown off as fine droplets from the through-holes 9 in the opening area of ​​the second concentric ring 74. Some of these high-speed droplets pass sequentially through the mass transfer plates 8 on the second concentric ring 74 and the first concentric ring 73, finally reaching the surface of the first concentric ring 73. The droplets collide, shear, and splash on both the mass transfer plates 8 and the first concentric ring 73, forming fine droplets and a constantly renewing liquid film. When the moving liquid reaches the mass transfer plate 8 of the second concentric ring 74, some of the liquid forms droplets and a liquid film, while some is accelerated and thrown off from the holes and edges of the mass transfer plate 8, moving to the mass transfer plate 8 of the first concentric ring 73, repeating the above process, and finally reaching the surface of the first concentric ring 73. Under the action of gravity and centrifugal force, the liquid is accelerated and thrown off from the bottom of the first concentric ring 73, moving to the adjacent second lower plate 72, entering the next cycle, until it leaves the rotor 7. The addition of the vertical radial mass transfer plate 8 continuously accelerates the liquid within the rotor 7, significantly reducing kinetic energy loss and fully utilizing the internal space of the rotor 7. This allows the liquid to undergo more dispersion and aggregation processes within the rotor 7. The vertical radial mass transfer plate 8 can be fixedly connected to the concentric rings or detachably connected, facilitating future replacement of the mass transfer plate 8. Specifically, for example... Figure 5 As shown, the concentric rings are provided with vertical slots 10, and the mass transfer plate 8 is provided with vertical retaining strips 11 corresponding to the vertical slots 10. The bottom of the vertical slots 10 is provided with threaded holes 101. The threaded holes 101 of the vertical slots 10 of the first concentric ring 73 are located at the bottom, and the threaded holes 101 of the vertical slots 10 of the second concentric ring 74 are located at the top. The vertical retaining strips 11 are provided with insertion holes 110 corresponding to the threaded holes 101. The threaded rod is threaded through the threaded hole 101, and the end of the rod is inserted into the insertion hole 110 to fix the position of the mass transfer plate 8 and prevent it from dislodging. Other limiting methods can also be used, as long as they achieve the effect of this application.

[0025] For reference Figure 8As shown, this application also provides a third embodiment, which is basically the same as the second and first embodiments, except that: the lower plate 72 is connected to the rotating rod 6, the upper plate 71 and the lower plate 72 have a vertical distance between them and the vertical distance is greater than the height of the concentric rings, the upper plate 71 is connected to the shell 1 by a screw, and the upper plate 71 has a hole in the middle, through which the air pipe 2 and the liquid inlet pipe 3 pass.

[0026] The upper plate 71 has its hole sidewall extending upward into the air intake pipe 16 and is provided with a sealing ring between it and the inner wall of the air intake pipe 16.

[0027] Specifically, such as Figure 8 As shown, in the third embodiment, the upper plate 71 is connected to the housing 1 by a screw. The upper plate 71 and the housing 1 are fixed together by the screw, and gas-liquid mass transfer is achieved only by the rotation of the lower plate 72. After the upper plate 71 is fixed, the side wall of the hole of the upper plate 71 extends upward into the air inlet pipe 16, and a sealing ring is installed between the upper plate 71 and the inner wall of the air inlet pipe 16 to ensure the sealing between the upper plate 71 and the air inlet pipe 16, and to ensure that the gas is smoothly discharged from the air outlet pipe 2.
