Description

Technical Field

[0001] The utility model relates to a distillation device, specifically to a supergravity split alcohol distiller. Background Art

[0002] The Chinese invention specification with the publication number of CN 216536946 U discloses a double-overflow high-efficiency alcohol recovery tower with a new structure, which includes: 1. A distillation kettle; 2. A transparent window; 3. A connecting pipe A; 4. A connecting pipe B; 5. A reboiler; 6. A steam inlet; 7. A pressure gauge; 8. A thermometer; 9. A steam pipe; 10. A distillation tower; 11. A liquid inlet pipe; 12. A distillation pipe; 13. A condenser; 14. A condensing pipe; 15. A voltage stabilizer; 16. A reflux pipe; 17. A dilute alcohol pipe; 18. A control valve A; 19. A control valve B; 20. A control valve C; 21. A concentrated alcohol pipe; 22. A cooler; 23. A recovery pipe; 24. A collection tank. The disadvantages of this double-overflow high-efficiency alcohol recovery tower with a new structure are as follows: 1. Due to the relatively traditional structure of the distillation tower 10, the alcohol distillation process is relatively slow, reducing the working efficiency. 2. The distillation tower 10 is huge in volume, generally more than ten meters high, resulting in a large occupied space. 3. During the production process, impurities are likely to accumulate inside the distillation kettle 1, so it is often necessary to open the equipment to clean its interior, resulting in inconvenient cleaning. Summary of the Invention

[0003] The utility model aims at the above deficiencies and provides a supergravity split alcohol distiller with high working efficiency, small occupied space and convenient cleaning.

[0004] The present utility model is realized as follows: A supergravity split alcohol distiller, which includes a dilute alcohol storage tank, a horizontal tube heater, a vertical evaporator tank body, and an alcohol storage tank. A first liquid outlet pipe with a control valve is connected to the dilute alcohol outlet at the bottom of the dilute alcohol storage tank. The right end of the first liquid outlet pipe is connected to a liquid pump. The outlet of the liquid pump is connected to a second liquid outlet pipe with a first branch pipe. The other end of the second liquid outlet pipe is connected to the dilute alcohol inlet at the top of the vertical evaporator tank body located on its right. An outlet is provided at the bottom of the vertical evaporator tank body, and the outlet is connected to the dilute alcohol inlet at the right end of the horizontal tube heater located at the lower left through a bent pipe. A steam alcohol outlet is provided at the top of the horizontal tube heater, and the steam alcohol outlet is connected to the inlet in the middle of the vertical evaporator tank body through a pipeline. The alcohol storage tank is located on the right of the vertical evaporator tank body. A condenser and a cooler are provided above the alcohol storage tank from left to right. The condenser is connected to the cooler on the right through a fourth pipeline. The cooler is connected to the third inlet of the alcohol storage tank through a fifth pipeline. A second return pipe is connected to the second lower outlet of the condenser. A second branch pipe and a third branch pipe are provided at the lower end of the second return pipe. The right lower end of the third branch pipe is connected to the second finished product inlet at the top of the alcohol storage tank. A steam outlet and a cleaning port are provided at the top of the vertical evaporator tank body. A retractable cleaning ball extending downward into the inner cavity of the vertical evaporator tank body is provided on the cleaning port. A supergravity centrifuge is provided between the vertical evaporator tank body and the condenser. A steam alcohol inlet and an inlet are respectively provided at the lower part and the middle part on the left side of the supergravity centrifuge. A second return port is provided at the upper part on the right side of the supergravity centrifuge. A second steam alcohol outlet and a first lower outlet are respectively provided at the top and the bottom of the supergravity centrifuge. The steam outlet of the vertical evaporator tank body is connected to the steam alcohol inlet of the supergravity centrifuge through a second pipeline. The first branch pipe of the second liquid outlet pipe is connected to the inlet of the supergravity centrifuge. The second steam alcohol outlet at the top of the supergravity centrifuge is connected to the steam alcohol inlet of the condenser located above and to the right of it through a third pipeline. The first lower outlet at the bottom of the supergravity centrifuge is connected to the return port at the top of the vertical evaporator tank body through a first return pipe. The left end of the second branch pipe is connected to the second return port at the upper part of the supergravity centrifuge.

[0005] With the above structure, the steam alcohol coming out of the vertical evaporator tank body enters the supergravity centrifuge through the second pipeline for gas-liquid separation. Since the supergravity centrifuge uses a rotating centrifugal force field to replace the gravity field of a conventional distillation tower, the relative separation speed of the gas-liquid two phases is greatly increased, and the production volume doubles, thereby improving the working efficiency. Second, since the volume of the supergravity centrifuge is only about 15% of the volume of a conventional distillation tower, it occupies less space. Third, a retractable cleaning ball is provided in the vertical evaporator tank body of the equipment, so that the cleaning is convenient. Description of the Drawings

[0009] Working principle: First, external steam enters the horizontal tube heater 2 through the steam inlet 2a for preheating. Then, the dilute alcohol in the dilute alcohol storage tank 1 flows out from the dilute alcohol outlet 1a and enters the vertical evaporator tank 3 through the first liquid outlet pipe 11, the liquid pump 12, and the second liquid outlet pipe 13. The dilute alcohol liquid that enters the vertical evaporator tank 3 falls to its bottom and then enters the horizontal tube heater 2 through the liquid outlet 3e and the elbow 24 for heating. After the dilute alcohol is heated to boiling (the vaporization point of alcohol is 78.3 °C), the vaporized alcohol rises and enters the vertical evaporator tank 3 through the vapor alcohol outlet 2d and the pipe 14 for re-heating and evaporation. During evaporation, the vapor alcohol passes through its steam outlet 3b and the second pipe 15 and enters the rotating packed bed 4 for gas-liquid separation. The separated vapor alcohol enters the condenser 5 through the second vapor alcohol outlet 4b and the third pipe 16 for condensation. During the condensation process, the unliquefied vapor alcohol enters the cooler 6 through the fourth pipe 17 for further cooling. The cooled finished alcohol enters the alcohol storage tank 7 through the alcohol outlet 6b of the cooler, the fifth pipe 18, and the first finished product inlet 7a. At the same time, the liquefied liquid alcohol in the condenser 5 flows out through the second return pipe 19. First, open the fourth control valve 193 to release a little alcohol for sampling and concentration testing. When the alcohol concentration meets the standard, open the third control valve 192, and the qualified alcohol enters the alcohol storage tank 7 through the third branch pipe 19b and the second finished product inlet 7b. When the alcohol concentration does not meet the standard, open the second control valve 191, and the low-concentration alcohol flows back to the rotating packed bed 4 through the second branch pipe 19a. The low-concentration alcohol that flows back into the rotating packed bed enters the horizontal tube heater 2 again through the first lower outlet 4d, the first return pipe 20, the vertical evaporator tank 3, and the elbow 24 for re-heating and evaporation to improve the recovery purity of the alcohol. And so on in a cycle. During the cyclic heating and flowing process, the waste liquid is discharged from the waste liquid outlet 2e of the horizontal tube heater. The utility model has a fast separation speed for dilute alcohol vapor, improves the evaporation capacity, and can be continuously produced.
