A regulating assembly 4 is provided on the side of the second distillation column 23. First, the heating tube 28 is turned on to heat the water in the distillation flask 21 to form water vapor. Then, triacetin is added to the second distillation column 23 through the conduit 24. Since the second distillation column 23 is provided with trays, the liquid flows from top to bottom under the action of gravity, and the gas passes through the liquid layer on the trays from bottom to top under the pressure difference, and heat exchange is carried out on each tray. In this process, low-boiling-point components evaporate more easily and rise to the top of the distillation column with the vapor, while high-boiling-point components tend to remain in the liquid and move downward. The rising vapor then enters the condenser 26 through the exhaust pipe 25, so that the vapor releases heat and converts into liquid during the condensation process, achieving separation.

[0031] Furthermore, if Figure 1 As shown: A collecting assembly 3 is provided on the side of the first distillation column 22 near the connecting pipe 27. The collecting assembly 3 includes a rotating shaft 32, and a guide rail 33 is rotatably connected to the rotating shaft 32. A collecting box 31 is provided on the side of the heating box 1 near the guide rail 33. A support member 35 is provided on the top of the heating box 1 near the collecting box 31. The collecting box 31 is located on the top of the support member 35. A screw 34 is threadedly connected between the support member 35 and the heating box 1. By providing the collecting assembly 3, the separated pure water can be collected and processed;

[0032] The above schemes also have the problem that for substances with similar boiling points, a fixed height distillation column cannot meet the separation effect, such as Figure 1 and Figure 3As shown: adjusting assembly 4 includes slide rail 41, slide rail 41 is provided with limiting piece 42, limiting piece 42 is connected with sliding block 43, sliding block 43 is connected with connecting rod 44, limiting piece 42 is provided with limiting block 47 away from sliding block 43, limiting block 47 is connected with connecting plate 45, connecting plate 45 top is provided with electric telescopic rod 46, electric telescopic rod 46 output end and connecting rod 44 are connected, connecting rod 44 is provided with extension rod 48 near one side of second distillation column 23, extension rod 48 is connected with sleeve 6, open electric telescopic rod 46, drive connecting rod 44 and sliding block 43 in slide rail 41 sliding up, thereby drive second distillation column 23 in first distillation column 22 sliding up, lifting height;

[0033] The above scheme also exists between the first distillation column 22 and the distillation flask 21 is not fixed, in the process of experiment, it is easy to appear the swing, influence the experimental result, such as Figure 4 As shown: the connecting part 5 is arranged at the connecting part between the distillation flask 21 and the first distillation column 22, the connecting part 5 comprises a connecting ring 51, the connecting ring 51 is provided with a clamping seat 52, the clamping seat 52 is provided with a bolt 53, by arranging the connecting part 5, the first distillation column 22 and the distillation flask 21 can be fixedly connected, so as to prevent the swing in the process of experiment;

[0034] Further, as shown in Figure 1 And Figure 2 As shown: sleeve 6 is provided with connecting piece near condenser 26, condenser 26 is provided with limiting ring 7, limiting ring 7 and connecting piece are connected, the bottom of heating box 1 is provided with bracket 8 near distillation flask 21, through setting connecting piece, condenser 26 can be fixed on second distillation column 23, through setting bracket 8, distillation flask 21 can be kept fixed.

[0035] Working principle: as shown in Figure 1 - Figure 4As shown, during the separation experiment, the heating tube 28 is first turned on to heat the water in the distillation flask 21 to form water vapor. Then, triacetin is added to the second distillation column 23 through the conduit 24. Since the second distillation column 23 is provided with trays, the liquid flows from top to bottom under the action of gravity, and the gas passes through the liquid layer on the trays from bottom to top under the pressure difference, and the mass and heat exchange is carried out on each tray. In this process, the low-boiling point component evaporates more easily and rises to the top of the distillation column with the steam, while the high-boiling point component tends to remain in the liquid and move downward. The rising steam then enters the exhaust pipe 25. In the condenser 26, the steam releases heat and converts into liquid during the condensation process to achieve separation. The distilled water will then fall into the collection box 31 at the bottom through the guide rail 33 for collection. When the boiling point of the substance is high, the electric telescopic rod 46 is turned on to drive the connecting rod 44 and the slider 43 to slide up in the slide rail 41, thereby driving the second distillation column 23 to slide up in the first distillation column 22, increasing the height of the distillation column to ensure sufficient condensation area and time. By setting the connecting component 5, the first distillation column 22 can be fixedly connected to the distillation flask 21 to prevent shaking during the experiment.
