Description

Technical Field

[0001] This utility model relates to the field of fractionation technology, specifically to a high-efficiency fractionation device. Background Technology

[0002] Fractional distillation is a method for separating mixtures with different boiling points. It involves heating a mixture and then cooling and separating the components into relatively pure single substances based on their different boiling points. Fractional distillation is essentially multiple distillations, and it is more suitable for separating and purifying liquid organic mixtures with similar boiling points. Fractional distillation is an important method for separating and purifying components of liquid organic mixtures with small differences in boiling points.

[0003] The following problems exist:

[0004] 1. Common fractionation devices are inefficient at separating multi-component mixtures and require the replacement of different storage tanks for the recovery of cooling liquid.

[0005] 2. In common fractionation devices, the sealing valve of the liquid storage tank can easily form a closed chamber with the liquid passage after it is closed, resulting in liquid residue in the pipeline, which affects the purity of different substances in subsequent distillation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please see Figure 1-3In this embodiment: a high-efficiency fractionation device includes a distillation tank 1, a temperature display screen 2 at the front end of the distillation tank 1, a boiler door 3 located at the lower end of the front end of the distillation tank 1 near the temperature display screen 2, a door handle 4 located at the front end of the boiler door 3, a sealing cover 5 connected to the upper end of the distillation tank 1, a liquid inlet pipe 6 extending through the upper end of the sealing cover 5, a heating chamber 7 located inside the distillation tank 1, a metal heat-conducting plate 8 connected to the upper end of the heating chamber 7, a distillation chamber 9 connected to the upper end of the metal heat-conducting plate 8, a liquid guide pipe 10 connected to one end of the distillation chamber 9, a cooling chamber 11 surrounding the outer surface of the liquid guide pipe 10, a first liquid storage tank 12 connected to the lower end of the liquid guide pipe 10, a second liquid storage tank 13 connected to the side of the lower end of the liquid guide pipe 10 near the first liquid storage tank 12, and a liquid guide pipe 10 near the side of the lower end of the liquid guide pipe 10 near the first liquid storage tank 12. A third liquid storage tank 14 is connected to one side of the 2. A first ball valve 15 is installed inside the liquid inlet pipe 6. A second ball valve 16 is installed inside the first liquid storage tank 12, the second liquid storage tank 13, and the third liquid storage tank 14 near the liquid guide pipe 10. A bracket 17 is connected to the lower end of the cooling chamber 11. The cooling chamber 11, the first liquid storage tank 12, the second liquid storage tank 13, the third liquid storage tank 14, and the second ball valve 16 are set up. By controlling the opening and closing of the second ball valve 16, the corresponding liquid storage tank is individually connected to the liquid guide pipe 10, so that the separated liquid is stored independently. By setting the second ball valve 16, the shape of the ball valve is changed to a slanted column, so that when the second ball valve 16 is closed, the upper end face of the end with the smaller height dimension is at the same level as the lower end face of the liquid guide pipe 10, so that the liquid will not remain in the liquid guide pipe 10.

[0026] In this embodiment, the boiler door 3 is movably connected to the distillation tank 1 via a hinge. A temperature sensor is installed inside the distillation chamber 9, and the temperature display screen 2 is electrically connected to the temperature sensor, making the temperature in the distillation chamber 9 controllable and thus achieving precise fractionation. A communicating vessel is installed at one end of the distillation tank 1, and a sealing ring is installed at the lower end of the sealing cover 5. This facilitates cleaning of the inside of the distillation tank 1 and ensures good airtightness during distillation when the distillation tank 1 is sealed, preventing gas leakage. The size of the first storage tank 12 is larger than that of the second storage tank 13; the size of the second storage tank 13 is larger than that of the third storage tank 14; the shape of the liquid guide pipe 10 is an inclined cylinder, and the upper dimensions of the first, second, and third storage tanks 12 and 13 are adapted to the inclination of the liquid guide pipe 10, making the connection between the storage tanks and the liquid guide pipe 10 more reasonable and stable. The ball valve 16 of the second ball valve is an inclined cylindrical shape, and the number of second ball valves 16... The system consists of three sets of storage tanks: the first storage tank 12, the second storage tank 13, and the third storage tank 14, which are movably connected to three sets of second ball valves 16 via bearings. The flow direction of the cooling liquid is controlled by controlling the closing of the second ball valves 16. The cooling chamber 11 is electrically connected to the support 17. The cooling chamber 11 has holes inside, and the inner diameter of the holes inside the cooling chamber 11 is adapted to the outer diameter of the liquid guide pipe 10. The cooling chamber 11 lowers the temperature in the liquid guide pipe 10, thereby causing the distilled gas to condense into liquid. One end of the distillation tank 1 is fixedly connected to the cooling chamber 11 by bolts. The outer surfaces of the first storage tank 12, the second storage tank 13, and the third storage tank 14 are equipped with drain valves. When the second ball valve 16 is closed, the upper end face of the end with the smaller height dimension is at the same level as the lower end face of the liquid guide pipe 10. After the second ball valve 16 is closed, the liquid will continue to flow downward under the influence of gravity, so that the liquid will not remain in the liquid guide pipe 10.

[0027] The working principle and usage process of this utility model are as follows: The user opens the first ball valve 15 and injects the liquid to be distilled into the distillation chamber 9 through the inlet pipe 6. At the same time, the user observes the liquid level in the communicating vessel at one end of the distillation tank 1, ensuring that the liquid level is lower than the height at which the liquid guide pipe 10 connects to the distillation chamber 9. Then, the user closes the second ball valve 16 on the first storage tank 12 and the second storage tank 13. Because of the inclined column design of the second ball valve 16, and the fact that one end is horizontal with the lower end face of the liquid guide pipe 10, the distilled liquid will not remain in the chamber formed by the second ball valve 16 and the liquid guide pipe 10. At this time, a temperature is set to heat the distillation chamber 9, causing one liquid in the mixture to separate and enter the third storage tank 14. After the component is safely separated, the user closes the second ball valve 16 on the third storage tank 14 and opens the second ball valve 16 on the second storage tank 13 to increase the distillation temperature, causing the second component in the mixture to separate. This process is repeated to completely separate the multi-component mixture. The cooling chamber 11 is used to cool the liquid guide pipe 10 and accelerate gas condensation.

[0028] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
