Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a high-efficiency condensation device for vacuum distillation. Background Technology

[0002] L-carnitine, commonly known as "carnitine," is a naturally occurring amino acid derivative in the human body. Medically, it's used to treat related deficiencies. In sports nutrition, it's used as a nutritional supplement to promote fat metabolism and relieve fatigue. In the production of L-carnitine, the electrodialysis solution is an aqueous solution, and water is removed by vacuum distillation until the solid precipitates. In traditional processing, the solvent condensation cycle is long, leading to a prolonged distillation process. This causes the crude L-carnitine to turn yellow, increasing the time required for subsequent purification and decolorization, resulting in low production efficiency and risks to product quality. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency condensation device for vacuum distillation, comprising a condenser tank, a tube sheet at the upper end of the condenser tank, a condenser tube penetrating through the lower end of the tube sheet, the condenser tube being arranged in a U-shape inside the condenser tank, an end plate at the upper end of the tube sheet, a coolant distribution shroud at one end of the condenser tube on one side of the upper surface of the end plate, a coolant collection shroud at the other end of the condenser tube on the other side of the upper surface of the end plate, a solvent input pipe at the middle of the end plate, the lower end of the solvent input pipe penetrating through the tube sheet and extending into the upper part of the condenser tank, a condenser cover covering the outer surface of the condenser tank, and a solvent output pipe penetrating through the condenser cover at the lower end of the condenser tank.

[0005] Preferably, the upper end of the coolant distribution cover is connected to a first coolant inlet pipe, the upper end of the coolant collection cover is connected to a first coolant outlet pipe, and the two ends of the condenser cover are respectively connected to a second coolant inlet pipe and a second coolant outlet pipe.

[0006] Preferably, the second coolant inlet pipe is located on the same side as the first coolant inlet pipe, and the second coolant outlet pipe is located on the same side as the first coolant outlet pipe.

[0007] Preferably, a sealing flange is provided at the upper outer edge of the condenser body, and the end plate and the tube plate are sealed to the sealing flange by bolts.

[0008] Preferably, an installation space is provided between the coolant distribution cover and the coolant collection cover, and the solvent input pipe is disposed inside the installation space.

[0009] Compared with the prior art, the beneficial effects of this utility model are: in the traditional processing, it replaces the traditional condensation equipment, shortens the solvent condensation cycle, thereby shortening the distillation process time, avoiding the yellowing of crude L-carnitine, shortening the subsequent refining and decolorization time, improving production efficiency, and thus ensuring product quality.

The upper end of the condenser tank 1 is provided with a tube sheet 2, and the lower end of the tube sheet 2 is provided with a condenser tube 3. The condenser tube 3 is arranged in a U-shape inside the condenser tank 1. The upper end of the tube sheet 2 is provided with an end plate 4. A coolant distribution cover 5 is provided on one side of the upper surface of the end plate 4 corresponding to one end of the condenser tube 3. A coolant collection cover 6 is provided on the other side of the upper surface of the end plate 4 corresponding to the other end of the condenser tube 3.

The outer surface of the condenser tank 1 is covered with a condenser cover 8. A solvent output pipe 9 is provided through the condenser cover 8 at the lower end of the condenser tank 1.

[0014] In use, a condenser tube 3 is sealed at the upper end of the condenser tank 1 via a tube sheet 2. A coolant distribution hood 5 and a coolant collection hood 6 are then sealed on the tube sheet 2 via end plates 4. The coolant is distributed to one end of the condenser tube 3 through the coolant distribution hood 5, and then collected and output through the coolant collection hood 6. The condenser tube 3 reduces the internal temperature of the condenser tank 1 through heat exchange. A condenser hood 8 is installed on the outer surface of the condenser tank 1 to reduce the internal temperature of the side wall of the condenser tank 1. The solvent to be condensed is introduced into the condenser tank 1 through a solvent inlet pipe 7. The solvent condenses on the condenser tube 3 and the inner wall of the condenser tank 1 upon encountering the cold. The condensed solvent is output through a solvent outlet pipe 9. The output end of the solvent inlet pipe 7 is positioned between the condenser tubes 3, so that the solvent introduced through the solvent inlet pipe 7 comes into contact with the condenser tube 3 immediately. The condenser hood 8 is installed on the outer side of the condenser tank 1 to further reduce the internal temperature of the condenser tank 1, thereby improving the condensation efficiency of the solvent.

[0015] The upper end of the coolant distribution cover 5 is connected to a first coolant inlet pipe 10, and the upper end of the coolant collection cover 6 is connected to a first coolant outlet pipe 11. The two ends of the condenser cover 8 are respectively connected to a second coolant inlet pipe 12 and a second coolant outlet pipe 13. Coolant is input into the interior of the coolant distribution cover 5 through the first coolant inlet pipe 10, and the coolant inside the coolant collection cover 6 is output to the outside through the first coolant outlet pipe 11. Coolant is input into the interior of the condenser cover 8 through the second coolant inlet pipe 12, and the coolant inside the condenser cover 8 is output to the outside through the second coolant outlet pipe 13.

[0016] The second coolant inlet pipe 12 is located on the same side as the first coolant inlet pipe 10, which facilitates the connection between the external coolant source and the first coolant inlet pipe 10 and the second coolant inlet pipe 12. The second coolant outlet pipe 13 is located on the same side as the first coolant outlet pipe 11, which facilitates the circulation of coolant after it is output from the first coolant outlet pipe 11 and the second coolant outlet pipe 13.

[0017] A sealing flange 14 is provided at the upper outer edge of the condenser tank 1. The end plate 4 and the tube plate 2 are connected to the sealing flange 14 by bolts to ensure the airtightness of the overall structure.
