[0002] A rectification column is a tower-type vapor-liquid contact device for rectification. By utilizing the property that each component in a mixture has different volatilities, that is, the vapor pressures of each component are different at the same temperature, the light components (low-boiling substances) in the liquid phase are transferred to the gas phase, while the heavy components (high-boiling substances) in the gas phase are transferred to the liquid phase, so as to achieve the purpose of separation. The rectification column is also a mass transfer and heat transfer device widely used in petrochemical production.

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a rectification device for the production of electrolyte additives, including a rectification tower 1 and a cleaning device for the top wall of the rectification tower. A feed pipe 2 is fixedly connected to the upper end of the rectification tower 1, a discharge port 3 is arranged on the lower side of the rectification tower 1, a heater 4 is installed at the bottom of the rectification tower 1, a conical top cover 5 is fixedly connected to the top of the rectification tower 1, a gas discharge pipe 6 is fixedly connected to the top of the conical top cover 5, a condenser 7 is fixedly installed at the top of the rectification tower 1, the right end of the gas discharge pipe 6 is fixedly installed at the input end of the condenser 7, a liquid discharge pipe 8 is fixedly installed on the right side of the condenser 7, a liquid storage tank 9 is fixedly connected to the surface of the rectification tower 1, and the lower end of the liquid discharge pipe 8 is fixedly connected to the top of the liquid storage tank 9.

[0025] The staff adds the electrolyte additive into the rectification tower 1 through the feed pipe 2. Then, the electrolyte additive inside the rectification tower 1 can be distilled by the heater 4. The vaporized liquid gradually moves upward and is discharged into the condenser 7 through the gas discharge pipe 6. The gas can be condensed by the condenser 7.

The circular ring frame 10 is fixedly connected to the inner wall of the rectification tower 1. An annular flow channel 11 is provided on the surface of the circular ring frame 10. The mounting frame 12 is fixedly connected to the inner surface of the circular ring frame 10. The rotating rod 13 is rotatably connected inside the mounting frame 12. Both cleaning plates 14 are fixedly connected to the top of the rotating rod 13. Both cleaning plates 14 are in contact with the bottom of the conical top cover 5.

The rotation of the rotating rod 13 can drive the two cleaning plates 14 at the top to rotate and clean the liquid adhering to the bottom of the conical top cover 5. Since the bottom of the conical top cover 5 is a slope structure, the liquid cleaned by the cleaning plates 14 can gradually flow downward and flow along the surface of the cleaning plates 14 into the internal of the annular flow channel 11. The liquid flows in the internal of the annular flow channel 11 and is discharged into the internal of the liquid storage tank 9 through the connecting elbow 19.

[0029] Working principle: For the rectification equipment for producing electrolyte additives, the staff adds the electrolyte additives into the rectification tower 1 through the feed pipe 2. Then, the electrolyte additives inside the rectification tower 1 can be distilled by the heater 4. The vaporized liquid gradually moves upward and is discharged into the internal of the condenser 7 through the gas discharge pipe 6. The gas can be condensed by the condenser 7. The condensed gas becomes a liquid state and flows into the internal of the liquid storage tank 9 through the liquid discharge pipe 8. The staff starts the driving motor 18. The output end of the driving motor 18 rotates to drive the rotating shaft 16 and the second bevel gear 17 to rotate. The rotation of the second bevel gear 17 can drive the first bevel gear 15 and the rotating rod 13 to rotate simultaneously. The rotation of the rotating rod 13 can drive the two cleaning plates 14 at the top to rotate and clean the liquid adhering to the bottom of the conical top cover 5. Since the bottom of the conical top cover 5 is a slope structure, the liquid cleaned by the cleaning plates 14 can gradually flow downward and flow along the surface of the cleaning plates 14 into the internal of the annular flow channel 11, and is discharged into the internal of the liquid storage tank 9 through the connecting elbow 19, avoiding waste of raw materials.
