[0002] The main structure of the supergravity distillation device includes a rotor, a liquid distributor and a shell, wherein the function of the rotor is to fix and drive the packing to rotate. The gas phase is introduced into the outer cavity of the supergravity machine through the gas inlet pipe, and enters the packing bed from the outer edge of the rotor under the action of gas pressure, and enters from the outside of the packing bed to the inside. The packing bed rotates under the drive of rotation, and the liquid is introduced into the distributor from the liquid inlet pipe and falls into the packing bed. Under the action of centrifugal force, the liquid is thrown to the outer edge of the rotor. In this process, the liquid is dispersed and broken by the packing to form a huge, constantly updated microelement, and the tortuous flow channel further aggravates the update of the interface. The liquid contacts the gas in reverse at a great relative speed under the conditions of high dispersion, high turbulence, strong mixing and rapid interface update, which greatly enhances the mass transfer process. Finally, the liquid is thrown to the shell by the rotor and collected, and then leaves the supergravity machine through the liquid outlet pipe. The gas leaves the rotor from the center of the rotor and is led out by the gas outlet pipe to complete the entire mass transfer and / or reaction process. However, the distributor and the packing bed of the prior art are often an integrated fixed design, which is very troublesome when the distributor and the packing bed need to be maintained, and it is impossible to disassemble them for maintenance.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Example

[0022] like Figure 1-5 As shown:

[0023] A supergravity distillation device comprises a shell 1, a steam exhaust pipe 2 is arranged on one side of the shell 1, a liquid inlet pipe 3 is arranged inside the shell 1, a rotating shaft 4 is arranged at the center of the shell 1, a packing bed 5 is arranged on the rotating shaft 4, a distributor 6 is arranged on the upper side of the packing bed 5, a center hole 7 is arranged on the distributor 6, the rotating shaft 4 is arranged inside the center hole 7, an air inlet pipe 8 is arranged on one side of the shell 1, a fixing frame 9 is arranged at the bottom of the shell 1, a reducer 10 connected to the rotating shaft 4 is embedded in the fixing frame 9, and a reducer 10 is arranged on the reducer 10 There is a motor 11, and a drain pipe 26 is provided at the bottom of the shell 1. It is characterized in that a bearing seat assembly is provided on the upper part of the shell 1, the bearing seat assembly is connected to the rotating shaft 4, the packing bed 5 is sleeved on the rotating shaft 4 through a sleeve 12, the rotating shaft 4 and the sleeve 12 are fixed by penetrating bolts and nuts, the liquid inlet pipe 3 and the distributor 6 are connected by a flange 13, a fixing plate 14 is provided at the bottom of the distributor 6, and a connecting plate 15 is provided on the inner wall of the shell 1, and the fixing plate 14 and the connecting plate 15 are fixed by bolts and nuts.

[0024] In the packed bed 5, the liquid is subjected to the dual effects of supergravity and friction, so that the liquid forms liquid films, liquid filaments and liquid droplets in the micrometer to nanometer scale, and produces a huge and rapidly updated phase interface, so that the flow rate of the gas-liquid phase and the effective specific surface area of ​​the packed bed 5 are greatly improved. The liquid contacts the gas in the curved flow channel at a very large relative speed in countercurrent under the conditions of high dispersion, high mixing, strong turbulence and rapid interface renewal, so that the gas-liquid phase can carry out efficient mass and heat transfer when passing through each layer of the packed bed 5, and is partially condensed and vaporized for multiple times, quickly reaching phase equilibrium, so that the mixture can be separated and purified in a very short time.

[0025] The principle of ultra-gravity distillation is the same as the ordinary principle. Both are based on the difference in relative volatility of each component in the solution. After multiple partial condensation and vaporization, the components can be separated. The difference is that the former completes this multiple partial condensation and vaporization process in the ultra-gravity field, and the separation effect is much greater than the ordinary distillation process. In essence, the most basic gas-liquid mass transfer unit in the traditional distillation process is the bubble, while in the ultra-gravity distillation process, there are only liquid films, liquid droplets and liquid filaments in the packed bed and the gas phase filling the packed bed space, without bubbles. The basic gas-liquid mass transfer is liquid film, liquid droplets and liquid filaments.

[0026] The core component of the supergravity rotating packed bed 5 forming the supergravity field is formed by the rotating shaft 4. Such a structure ensures efficient mass transfer between gas and liquid in the supergravity field. The gas and liquid flow regularly along the specified channels in the core component without short circuits. The liquid is continuously dispersed and gathered, and the surface renewal rate is fast. There is a series of efficient "end effects" in the entire component. The dynamic baffle 23 and the static baffle 22 can play the role of liquid distribution and redistribution, and there are a series of dynamic and static baffles in the component, so the liquid is evenly distributed in the entire component, and the amplification effect is small.

[0027] During the rotation of the packed bed 5, the liquid undergoes multiple dispersion-aggregation processes, and the gas undergoes a tortuous flow process. The hot gas enters the housing 1 through the liquid inlet pipe 3, the motor 11 drives the reducer 10 to rotate, the reducer 10 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the sleeve 12 and the packed bed 5 to rotate, the gas enters from the outside of the packed bed 5 to the inside of the packed bed 5, the liquid enters through the liquid inlet pipe 3, then enters the distributor 6, and then falls on the packed bed 5. Under the centrifugal force of the rotating packed bed 5, it is thrown out to the outer circle, and is atomized and divided by the packing on the packed bed 5, and is fully refined and contacted with the hot air flow coming from the opposite direction, realizing the transfer of the medium, the liquid is heated and distilled, and the components with lower evaporation temperature in the liquid evaporate and are discharged through the exhaust pipe 2, while the unevaporated liquid is discharged from the bottom of the housing 1 through the liquid discharge pipe 26.

[0028] The bearing seat assembly includes an upper bearing seat 16 and a lower bearing seat 17. The upper bearing seat 16 and the lower bearing seat 17 are fixed by bolts and nuts, and the lower bearing seat 17 and the housing 1 are fixed by bolts and nuts. Bearings 25 are arranged in the upper bearing seat 16 and the lower bearing seat 17, and a rotating shaft 4 is arranged in the bearing 25.

[0029] The upper bearing seat 16 and the lower bearing seat 17 are separated by removing the bolts and nuts between them, and the lower bearing seat 17 and the housing 1 are separated by removing the bolts and nuts between them. The upper bearing seat 16 and the lower bearing seat 17 are removed, and the bearing 25 is removed from the rotating shaft 4.

[0030] The housing 1 includes an upper housing 18 and a lower housing 19 , which are connected by bolts and nuts. The upper housing 18 and the lower housing 19 can be separated from each other by unscrewing the bolts and nuts between the upper housing 18 and the lower housing 19 .

[0031] An L-shaped liquid inlet pipe 20 is disposed in the upper shell 18 to facilitate the input of the liquid source on the upper side into the outer shell 1 .

[0032] The upper shell 18 is provided with a filter cotton 21 to intercept heavy impurities in the separated volatilized gas before it is discharged through the exhaust pipe 2 .

[0033] The distributor 6 is provided with a static baffle 22 at the bottom, and a dynamic baffle 23 is provided on the packed bed 5. The static baffle 22 is located between the dynamic baffles 23. The liquid in the distributor 6 passes through the static baffles 22 and falls into the dynamic baffles 23. Under the action of centrifugal force, it flows to the next dynamic baffle 23 and is then dispersed into fine droplets again. This process is repeated until it reaches the outer edge of the packed bed 5.

[0034] The housing 1 is provided with a sealing tube 24 , and a liquid inlet pipe 3 is provided inside the sealing tube 24 . The liquid inlet pipe 3 is inserted into the sealing tube 24 and then connected to the distributor 6 , thereby ensuring the sealing between the liquid inlet pipe 3 and the housing 1 .

[0035] The packing of the packing bed 5 is a wave baffle, which makes the gas and liquid cut and differentiated more delicately and the gas and liquid contact more fully.

[0036] The method of using the utility model is as follows:

[0037] First, remove the bolts and nuts between the upper bearing seat 16 and the lower bearing seat 17 to separate the upper bearing seat 16 and the lower bearing seat 17, remove the bolts and nuts between the lower bearing seat 17 and the outer shell 1 to separate the lower bearing seat 17 and the outer shell 1, remove the upper bearing seat 16 and the lower bearing seat 17, remove the bearing 25 from the rotating shaft 4, remove the bolts and nuts between the upper shell 18 and the lower shell 19, then remove the upper shell 18 from the lower shell 19, remove the flange 13 between the liquid inlet pipe 3 and the distributor 6 to separate the liquid inlet pipe 3 from the distributor 6, then unscrew the bolts and nuts on the fixing plate 14 and the connecting plate 15 to separate the distributor 6 from the connecting plate 15, and then unscrew the bolts and nuts on the rotating shaft 4 and the sleeve 12 to separate the packing bed 5 from the rotating shaft 4, and then take the distributor 6 and the packing bed 5 out of the outer shell 1 from bottom to top along the rotating shaft 4, thereby realizing the separate disassembly of the distributor 6 and the packing bed 6.
