Description

Technical fields:

[0001] This utility model relates to a rotary extraction tower with louvers. Background technology:

[0002] Mechanically powered extraction columns can promote mass transfer between liquid and liquid phases through mechanical force. Rotary disc extraction columns are a crucial type of mechanically enhanced extraction equipment. However, while mechanical force enhances liquid-liquid mass transfer, it also reduces the throughput of the extraction column. Furthermore, the addition of structures such as baffles and rotating discs causes localized retention of the dispersed phase, resulting in insufficient surface renewal and thus reducing mass transfer efficiency. Utility model content:

[0003] This invention addresses the problems existing in the prior art by providing a louvered rotary extraction tower with a reasonable design that increases liquid-liquid throughput, promotes droplet dispersion, and improves mass transfer efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a louvered rotary extraction tower, comprising an extraction tower body with a vertically mounted rotating shaft inside, wherein multiple conical annular baffles are evenly distributed vertically inside the extraction tower body, and a number of louvered rotary discs are evenly distributed along the axial direction of the rotating shaft between two adjacent conical annular baffles, wherein the louvered rotary discs are mounted on the rotating shaft, and the surface of the fan blades of the louvered rotary discs is provided with vertically penetrating sieve holes.

[0005] Furthermore, the louvered turntable includes a fan blade fixing ring, on the inner circumference of which multiple fan blades are evenly distributed. Multiple screen holes are opened on the surface of the fan blades. The multiple fan blades are radially distributed around the axis of the fan blade fixing ring, and the adjacent ends of the multiple fan blades form a mounting hole for cooperating with the rotating shaft.

[0006] Furthermore, the diameter of the louvered disc is 0.7-0.9 times the inner diameter of the extraction column.

[0007] Furthermore, one to three louvered turntables are provided between two adjacent conical annular baffles.

[0008] Furthermore, the fan blade has an inclination angle of 10° to 45°, a width of 20mm to 50mm, an opening rate of 20% to 50% on the fan blade surface, and a sieve hole diameter of 5mm to 8mm, with the sieve holes arranged in a triangular pattern.

[0009] Furthermore, the cone angle of the conical annular baffle is 160° to 170°, and the inner ring diameter of the conical annular baffle is 1 / 4 to 1 / 2 of the inner diameter of the extraction column.

[0010] Furthermore, the conical annular baffle is coaxially arranged with the rotating shaft, and the conical annular baffle is fixed to the inner wall of the extraction column body.

[0011] Furthermore, the small-diameter port of the conical annular baffle is a conical opening. When the heavy phase is the dispersed phase, the conical opening faces downwards, and when the light phase is the dispersed phase, the conical opening faces upwards.

[0012] Furthermore, after the louvered turntable rotates, the axial flow direction is consistent with the continuous phase flow direction, and the rotational speed of the louvered turntable is 10rpm-120rpm.

[0013] Furthermore, the rotating shaft is driven to rotate by a motor installed at the top of the extraction tower.

[0014] Compared with the prior art, the present invention has the following effects: The present invention has a reasonable structural design. By adopting a perforated louvered turntable and a conical annular baffle, the liquid-liquid flux is increased, the dispersion of liquid droplets is promoted, the mass transfer area between the two phases is increased, and the liquid-liquid extraction process is strengthened.

[0024] like Figures 1-5 As shown, this utility model discloses a rotary disc extraction tower, comprising an extraction tower body 1 with a vertically mounted rotating shaft 12 inside. Multiple conical annular baffles 4 are evenly distributed vertically within the extraction tower body 1, coaxially arranged with the rotating shaft 12 and fixed to the inner wall of the extraction tower body 1. The surface of the conical annular baffles 4 is not perforated. Between adjacent conical annular baffles 4, several rotary discs 3 are evenly distributed along the axial direction of the rotating shaft 12. The rotary discs 3 are mounted on the rotating shaft 12, and as the rotating shaft 12 rotates, the blades 11 of the rotary discs 3 have vertically penetrating sieve holes 14 on their surfaces. The perforations (sieve holes) on the blades of the rotary discs, combined with the conical annular baffles, effectively increase the liquid-liquid flux, promote the breakup of dispersed phase droplets, increase the mass transfer area between the two phases, and enhance the liquid-liquid extraction process.

[0025] In this embodiment, the louvered turntable 3 includes a fan blade fixing ring 13 coaxially arranged with the rotating shaft. Multiple fan blades 11 are evenly distributed on the inner circumference of the fan blade fixing ring 13. Multiple screen holes 14 are opened on the surface of each fan blade 11. The multiple fan blades 11 are radially distributed around the axis of the fan blade fixing ring 13. The adjacent ends of the multiple fan blades 11 form a mounting hole 15 for cooperating with the rotating shaft 12. The rotating shaft is fixedly inserted through the mounting hole.

[0026] In this embodiment, the diameter of the louvered turntable 3 (i.e., the outer diameter of the fan blade fixing ring) is 0.7-0.9 times the inner diameter of the extraction tower body 1.

[0027] In this embodiment, 1-3 louvered discs 3 are provided between two adjacent conical annular baffles 4 to realize multiple coalescence and dispersion of the dispersed phase, effectively renew the mass transfer interface, and at the same time promote the flow of the continuous phase and increase the fluid flux through the action of the louvered discs.

[0028] In this embodiment, the tilt angle of the fan blade 11 is 10° to 45°.

[0029] In this embodiment, the width of the fan blade 11 is 20mm to 50mm.

[0030] In this embodiment, the perforation rate of the fan blade 11 surface is 20% to 50%.

[0031] In this embodiment, the aperture of the sieve is 5mm to 8mm.

[0032] In this embodiment, the sieve holes 14 on the surface of the fan blade 11 are distributed in a triangular pattern.

[0033] In this embodiment, the cone angle of the conical annular baffle 4 is 160° to 170°.

[0034] In this embodiment, the inner ring diameter of the conical annular baffle 4 is 1 / 4 to 1 / 2 of the inner diameter of the extraction column body 1.

[0035] In this embodiment, the small-diameter port of the conical annular baffle 4 is a cone 10. When the heavy phase is the dispersed phase, the cone 10 faces downwards, and when the light phase is the dispersed phase, the cone 10 faces upwards.

[0036] In this embodiment, after the louvered turntable 3 rotates, the axial flow direction is consistent with the continuous phase flow direction, and the rotation speed of the louvered turntable is 10rpm-120rpm.

[0037] In this embodiment, the rotating shaft 12 is driven to rotate by a motor 9 installed at the top of the extraction tower body 1.

[0038] Example 1

[0039] The heavy phase is fed into the extraction column body 1 from the heavy phase inlet 2 at the top of the column and flows downward as a continuous phase. The light phase, as a dispersed phase, is fed into the extraction column body 1 from the light phase inlet 7 at the bottom of the column and flows upward. The two phases flow countercurrently within the extraction column. After liquid-liquid mass transfer separation, the heavy phase is discharged from the heavy phase outlet 6 at the bottom of the column, and the light phase leaves the extraction column from the light phase outlet 8 at the top of the column. Ten conical annular baffles are evenly distributed inside the column. The conical annular baffles 4 have a cone opening 10 facing downward, a cone angle of 160°, and an inner ring straight. The diameter is 1 / 4 of the inner diameter of the tower. Three louvered turntables 3 are evenly distributed along the axis of the rotating shaft 12 between adjacent conical annular baffles 4. The diameter of the louvered turntables 3 is 0.7 times the inner diameter of the tower. The fan blades 11 are tilted at an angle of 10° and have a width of 20 mm. The surface of the fan blades 11 has sieve holes 14 with a diameter of 5 mm. The sieve holes 14 are triangularly distributed with an opening rate of 20%. The louvered turntables 3 are driven by the motor 9 to rotate the rotating shaft 12 clockwise at a speed of 10 rpm.

[0040] Example 2

[0041] The light phase, as a continuous phase, is fed into the extraction column from the bottom (light phase inlet 7) and flows upwards. The heavy phase is fed into the extraction column from the top (heavy phase inlet 2) and flows downwards as a dispersed phase. The light and heavy phases flow countercurrently within the extraction column body 1. After liquid-liquid mass transfer separation, the heavy phase is discharged from the bottom (heavy phase outlet 6), and the light phase leaves the extraction column from the top (light phase outlet 8). Ten conical annular baffles 4 are evenly distributed inside the column, with the cone openings 10 facing upwards, a cone angle of 170°, and an inner ring diameter equal to the column's inner diameter. 1 / 2; Two louvered turntables 3 are evenly distributed along the axis of the rotating shaft 12 between adjacent conical annular baffles 4. The diameter of the louvered turntable 3 is 0.9 times the inner diameter of the tower. The fan blade 11 has an inclination angle of 45° and a width of 50 mm. The surface of the fan blade 11 is opened with sieve holes 14. The sieve holes 14 have a diameter of 8 mm and are distributed in a triangular pattern with an opening rate of 50%. The louvered turntable 3 is driven by the motor 9 to rotate the rotating shaft 12 clockwise at a speed of 120 rpm.

[0042] The advantages of this utility model are: (1) By opening holes in the fan blades of the louvered turntable and then combining them with a conical annular baffle, the liquid-liquid flux is effectively increased, the dispersion of the liquid droplets is promoted, the mass transfer area between the two phases is increased, and the liquid-liquid extraction process is strengthened; (2) A louvered turntable with 1-3 levels of openings is set between adjacent conical annular baffles to realize multiple aggregation and dispersion of the dispersion phase, effectively renewing the mass transfer interface, and at the same time promoting the flow of the continuous phase and increasing the fluid flux through the action of the louvered turntable; (3) The traditional annular baffle is improved into a conical annular baffle, which can effectively prevent the dispersion of the liquid droplets from being trapped by the baffle and effectively improve the mass transfer efficiency.
