Description

Technical Field

[0001] The utility model relates to the technical field of reflux ratio regulation, in particular to a reflux ratio controller. Background Art

[0002] A distillation tower is a tower-type gas-liquid contact device for distillation. It utilizes the different volatilities of the components in the mixture, that is, the different vapor pressures of the components at the same temperature, to transfer the light components (low boiling substances) in the liquid phase to the gas phase, and the heavy components (high boiling substances) in the gas phase to the liquid phase, thereby achieving the purpose of separation.

[0003] The steam at the top of the distillation tower needs to be condensed into liquid through a condenser. In order to improve the purity of the separated product, the condensed liquid needs to be refluxed to the distillation tower. In this process, adjusting the reflux ratio can affect the component concentration and separation effect of each plate section in the distillation tower, thus playing a vital role in the separation efficiency and the purity of the final product. Based on this, it is urgent to develop a device that can adjust the reflux ratio. Utility Model Content

[0024] The utility model provides a reflux ratio controller suitable for a distillation tower. The distillation tower is used for distilling corrosive chemicals. The distillation tower is connected to a condenser. Steam at the top of the distillation tower is condensed into liquid through the condenser to form condensate.

[0025] like Figure 1-Figure 2 As shown, the reflux ratio controller includes: an outer cylinder 1, the outer cylinder 1 is provided with a leveling device (not shown in the figure), which is convenient for adjusting the equipment to a horizontal level before use, the thickness of the upper cover plate and the lower base plate of the outer cylinder 1 is set according to the negative pressure conditions in the actual use environment to meet the strength requirements for use under negative pressure conditions, a liquid receiving cup 8 is arranged in the outer cylinder 1, and an annular gap is arranged between the inner wall of the outer cylinder 1 and the outer wall of the liquid receiving cup 8, so that the vacuum can penetrate smoothly under reduced pressure conditions, and a longitudinal partition plate 6 is also arranged below the liquid receiving cup 8.

[0026] Specifically, Figure 2-Figure 4 As shown, the outer cylinder 1 is provided with a liquid inlet pipe 2, and the liquid inlet pipe 2 is located in the axial area above the liquid receiving cup 8, so that the condensed liquid introduced by the liquid inlet pipe 2 can all enter the liquid receiving cup 8 to avoid falling into the annular gap between the outer cylinder 1 and the liquid receiving cup 8. A reflux port 3 and a production port 4 are provided at the bottom of the outer cylinder 1, and the reflux area where the reflux port 3 is located and the production area where the production port 4 is located are separated by a longitudinal partition plate 6. The reflux port 3 is connected to the distillation tower through a pipeline, and a part of the condensed liquid refluxes into the distillation tower through the reflux port 3, and the other part of the condensed liquid is produced through the pipeline connected to the production port 4.

[0027] Further, such as Figure 5 As shown, a fan-shaped hole distribution area is set at the bottom of the liquid receiving cup 8, and a number of evenly distributed through holes 81 are opened in the hole distribution area, so that a sieve plate structure is formed at the bottom of the liquid receiving cup 8. The through holes 81 are radially distributed along the radial direction of the liquid receiving cup 8, and the angle between two adjacent rows of through holes 81 is 18°.

[0028] like Figure 1-Figure 3 As shown, a stator 5 is fixedly installed in the outer cylinder 1, a longitudinal partition 6 is connected to the stator 5, the stator 5 is connected to the rotor 7, a flat fitting surface is set between the stator 5 and the rotor 7 to achieve smooth rotation, the rotor 7 is connected to the liquid holding cup 8, the liquid holding cup 8 is fixedly installed with a rotating shaft 9, the rotating shaft 9 passes through the upper cover plate of the outer cylinder 1, a sealing ring is set between the rotating shaft 9 and the upper cover plate of the outer cylinder 1, a handle 10 is fixedly installed at one end of the rotating shaft 9, a dial 11 is set on the upper cover plate of the outer cylinder 1, a pointer is fixedly installed on the rotating shaft 9, the pointer rotates with the rotating shaft 9, the operator can adjust the reflux ratio by the pointer pointing to the indication of the dial 11, when the liquid holding cup 8 is rotated to make the condensate in a full reflux state, the pointer points to the starting line of the dial 11, at this time, the angle between a row of through holes 81 close to the starting line of the dial 11 (this row of through holes 81 is the edge row of through holes 81 of the liquid holding cup 8) and the starting line of the dial 11 is 9°.

[0029] In this embodiment, the handle 10 is rotated to the required reflux ratio based on the indication of the dial 11. The handle 10 drives the rotating shaft 9 to rotate during the rotation process, and the rotating shaft 9 drives the liquid receiving cup 8 to rotate. Rotating the liquid receiving cup 8 can adjust the relative position of the hole distribution area in the liquid receiving cup 8 and the longitudinal partition 6, and then adjust the ratio of liquid flowing from the hole distribution area on both sides of the longitudinal partition 6, so that the liquid flow from the hole distribution area to both sides of the longitudinal partition 6 is quantitatively distributed in a geometric segmentation manner to achieve the adjustment of the reflux ratio. After the adjustment is completed, the condensed liquid is passed into the outer cylinder 1 through the liquid inlet pipe 2, the condensed liquid falls into the liquid receiving cup 8 and is distributed in the reflux area and the production area below it through the through holes 81 in the hole distribution area. The condensed liquid in the reflux area is refluxed to the distillation tower through the reflux port 3, and the condensed liquid in the production area is produced through the pipeline connected to the production port 4.

[0030] Working principle: Turn the handle 10 to the required reflux ratio.

Rotating the liquid receiving cup 8 can adjust the relative position of the hole distribution area in the liquid receiving cup 8 and the longitudinal partition 6, and then adjust the ratio of the liquid flowing from the hole distribution area to the two sides of the longitudinal partition 6, so that the liquid flow from the hole distribution area to the two sides of the longitudinal partition 6 is quantitatively distributed in a geometrically divided manner.
