Description

Technical Field

[0001] The invention relates to the technical field of extraction, in particular to a centrifugal high-efficiency extraction tower. Background Art

[0002] Extraction is a unit operation that separates a mixture by utilizing the different solubilities of components in a system in a solvent. Specifically, extraction is a method of transferring a solute from one solvent to another by utilizing the differences in solubility or distribution coefficients of a substance in two immiscible (or slightly soluble) solvents. After repeated extractions, most of the compounds can be extracted.

[0003] A Chinese invention patent with publication number CN215653931U discloses a vertical high-efficiency extraction tower for sodium hydroxide extraction and separation, comprising: an extraction tower body, a fixed partition welded in the extraction tower body, a motor installed on the top of the extraction tower body by bolts, a rotating rod arranged in the extraction tower body, the rotating rod is installed on the output shaft of the motor, a control disk is welded on the rotating rod, a through hole is arranged on the control disk, the rotating rod is arranged in the through hole, a mounting groove is arranged at the bottom of the fixed partition, the control disk is clamped in the mounting groove, a turntable is welded at the bottom of the control disk, a fixed frame is welded on one side of the extraction tower body, a circulating pump is installed on the fixed frame by bolts, the circulating pump is connected to the bottom and top of the extraction tower body respectively through pipelines, a wiring plug and a switch group are arranged on the extraction tower body, the wiring plug is connected to the switch group through wires, and the switch group is connected to the motor and the circulating pump respectively through wires. The utility model has the characteristics of thorough extraction and can prevent mixing.

[0004] In addition, since the invention feeds liquid through a feed port, the liquid tends to gather near the feed port after entering the extraction tower, resulting in excessively high liquid concentration in the local area, so that on the cross section of the extraction tower, the solute concentration in the part close to the feed port is much higher than that in other areas. This uneven distribution will cause the local contact and mass transfer conditions of the extraction phase and the residual phase to be different from those in other areas. In areas where the solute concentration is too high, the extraction phase may reach saturation in a short time and cannot continue to effectively extract the solute; while in areas where the solute concentration is low, the extraction phase may not be fully utilized, thereby reducing the overall extraction efficiency. In addition, when the surface tension and viscosity of the two liquids are small, because the lower surface tension is conducive to the dispersion of the liquid, and the higher viscosity will hinder the aggregation of droplets, and then easily form an emulsion, the vertical high-efficiency extraction tower for sodium hydroxide extraction and separation disclosed by Chinese invention patent CN215653931U cannot improve the extraction efficiency, nor can it avoid the emulsification phenomenon affecting the purity of the extraction.

[0040] Furthermore, the centrifugal mechanism 5 includes a diverter slot plate 51 which is fixedly connected to the top of the extraction box 41, and diverter holes 52 are cross-symmetrically opened on the outer wall of the diverter slot plate 51, and a discharge slot plate 53 is fixedly connected to the inner wall of the diverter hole 52, and a collecting slot 54 is opened at the bottom of the inner cavity of the diverter slot plate 51.

[0042] The centrifugal block 512 is driven to rotate by the centrifugal plate 511, so that the centrifugal block 512 rotates synchronously with the mixed extract, so that the extract on the top of the centrifugal plate 511 performs centrifugal motion, so that the two are separated according to their own density, and then the separated liquid in different parts is guided and separated by the second diverter plate 58.

[0043] The following is the working process and principle of the above embodiment:

[0044] The working steps are as follows:

[0045] First, the operator connects the feeding valve 42 to the pipelines for conveying the extraction phase and the raffinate phase, respectively, so that the extraction phase and the raffinate phase enter the feeding box 2 synchronously. At the same time, the operator controls the driving motor 56 and the heating device inside the water tank 410 through the external control device to be energized, so that the heating device inside the water tank 410 heats the water flow inside the water tank 410 to an appropriate temperature, so that the driving motor 56 drives the rotating end of the driving rod 57 to start rotating, so that the rotating end of the driving rod 57 drives the fixed rod 43 to rotate synchronously, so that the fixed rod 43 drives the stirrer 44 to rotate synchronously inside the feeding box 2, and then the stirrer 44 stirs the two solutions, so that the extraction phase is extracted. The extracted phase is fully mixed with the residual phase. After the solutions are mixed, they enter the inside of the cylinder 46 through the inside of the circular groove disk 1 45, then enter the inside of the circular groove disk 2 47 through the inside of the cylinder 46, and finally enter the inside of the extraction box 41 through the circular groove disk 2 47, so that the solutions move upward and enter the inside of the guide port 412 respectively. Different solutions are fed through the feeding valve 42 and then stirred by the agitator 44, thereby avoiding feeding through one feeding port, preventing different solubility of mixed solutions in different areas of the feeding box 2, and preventing the extraction phase from being underutilized, thereby improving the utilization rate of the extraction phase.

[0046] After the solutions enter the interior of the guide port 412 respectively, the solutions enter the interior of the groove 1 411, so that the temperature of the water flow in the water tank 410 is transferred to the interior of the solution by heat conduction, thereby uniformly heating the mixed solution, so that the heated solution flows out through the guide port 412 set on the top of the heating plate 49, and the solution enters the top of the centrifugal plate 511 through the groove 2 513, so that the centrifugal plate 511 drives the centrifugal block 512 and the solution on the top of the centrifugal plate 511 to rotate synchronously, so that the solution on the top of the centrifugal plate 511 performs centrifugal motion. When the mixed solution performs centrifugal motion, since the centrifugal forces on solutions of different densities are different, the deviation angles of the solutions are also different. The mixed solution is driven to perform centrifugal motion by the centrifugal block 512, so that the raffinate phase and the extraction phase are separated by centrifugal force, thereby improving the extraction efficiency of the device. Therefore, as the solution on the top of the centrifugal plate 511 gradually increases, the solution separated by the centrifugal motion is zoned under the guidance of the diverter trough plate 2 58. The extraction phases and the residual phases are separated, so that different extraction phases and the residual phase enter the interior of the second diverter trough plate 58 and the top of the extraction box 41 respectively, and then the solution in the second diverter trough plate 58 enters the interior of the chute 59, and the solution in the chute 59 enters the guide inclined plate 510, so that the solution enters the interior of the second collecting trough 55 through the guide inclined plate 510, and finally the interior of the second collecting trough 55 is discharged through the discharge trough plate 53 connected thereto, and at the same time, the solution entering the top of the second diverter trough plate 58 passes through the extraction box 41, enters the interior of the collecting trough 1 54, and then enters the interior of the discharge trough plate 53 connected thereto through the collecting trough 1 54 and then is discharged, and the mixed solution in the groove 1 411 is heated by the water heated in the water tank 410, so that the temperature of the mixed solution can reduce the viscosity and surface tension of the liquid, avoid the small droplets in the emulsion from being easily aggregated, and avoid changing the properties and solubility of the emulsifier, thereby reducing the stability of the emulsion, and thereby improving the purity of the mixed solution after extraction.
