Description

Technical Field

[0001] This utility model relates to the field of distillation equipment technology, specifically a distillation column. Background Technology

[0002] A distillation column is a tower-type vapor-liquid contact device for distillation. It utilizes the property that the components in a mixture have different volatility, i.e., different vapor pressures at the same temperature, to transfer lighter components from the liquid phase to the gas phase, while heavier components from the gas phase transfer to the liquid phase, thereby achieving separation.

[0003] Existing distillation columns have low tray efficiency during actual operation and cannot be flexibly adjusted according to different compositions and flow rates of raw materials, resulting in unsatisfactory gas-liquid mass transfer and poor distillation separation. Utility Model Content

A sealing mechanism 2 is provided above the column body 1. A mass transfer mechanism 3 is provided inside the column body 1. The mass transfer mechanism 3 includes two first chutes 301, which are respectively opened on the left and right sides of the inner wall of the column body 1. A number of sliders 302 are arranged inside the first chutes 301. A column plate 303 is fixedly connected to one side of the slider 302. A number of air holes 304 are opened on the upper surface of the column plate 303. Overflow weirs 305 are fixedly connected to both sides of the upper surface of the column plate 303. A discharge port 306 is opened in the middle of one side of the upper surface of the column plate 303. A discharge pipe 307 is fixedly connected to the middle of one side of the lower surface of the column plate 303. Material and steam enter the interior of tower body 1 through feed pipe 101 and air inlet pipe 102, respectively. Two first sluices 301 are respectively fitted into the middle of the left and right sides of the inner wall of tower body 1. Slider 302 can slide up and down inside the first sluices 301. Tower plate 303 can move up and down inside tower body 1 through slider 302. Air hole 304 penetrates the interior of tower plate 303. The bottom of two overflow weirs 305 above a single tower plate 303 is vertically connected to the left and right sides of the upper surface of tower plate 303, respectively. Feed port 306 penetrates the middle of one side of tower plate 303 and communicates with feed pipe 307. Gas rises from the lower tower plate 303 to the upper tower plate 303 through air hole 304 and disperses in the liquid on tower plate 303 to achieve gas-liquid contact mass transfer. Overflow weir 305 and feed pipe 307 are used to guide the orderly flow of liquid between tower plates 303.

[0025] Specifically, such as Figure 3As shown, a second sliding groove 308 is provided in the middle of the back side of the inner wall of the tower body 1, and a threaded shaft 309 is fixedly connected to the middle of the back side of the tower plate 303. A nut 310 is provided on the outer surface of the threaded shaft 309.

[0026] Through the above technical solution, the second slide groove 308 is fitted into the middle of the back side of the inner wall of the tower body 1, and one end of the threaded shaft 309 is vertically connected to the middle of the back side of the tower plate 303. It can slide up and down inside the second slide groove 308, and the nut 310 and the threaded shaft 309 can rotate in a threaded manner, which is responsible for fixing the position of the threaded shaft 309 and the tower plate 303.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, the sealing mechanism 2 includes an external thread 201, which is located above the outer surface of the tower body 1. A threaded cap 202 is located above the upper surface of the tower body 1. An air outlet pipe 203 is fixedly connected to the middle of the upper surface of the threaded cap 202, and a material outlet pipe 204 is fixedly connected to the middle of the lower surface of the tower body 1.

The steam and materials inside the tower body 1 are discharged through the gas outlet pipe 203 and the material outlet pipe 204, respectively.

[0029] During use, the operator can flexibly adjust the spacing between the trays 303 according to the different compositions and flow rates of the raw materials. After adjustment, the nut 310 is turned to fix its position. After adjustment, the threaded cap 202 is screwed on the top of the tower body 1 to seal its interior. The material enters the tower body 1 through the feed pipe 101 and the air inlet pipe 102 for heat transfer. The reacted material is discharged outward through the discharge pipe 204 at the bottom, and the steam is discharged through the air outlet pipe 203 at the top.
