Description

Technical Field

[0001] The utility model relates to the field of chemical equipment, in particular to a distillation device. Background Art

[0002] Distillation is a common separation process that exploits the different boiling points of components in a liquid or solid-liquid mixture to separate the lower-boiling-point component by evaporating and then condensing it. In the pharmaceutical and chemical industries, distillation is often required to separate the final product or intermediates during the preparation of certain substances.

[0003] In the existing distillation device, when condensing, the condenser tube is prone to reflux when it crosses the vaporization device and the collection device. To solve the reflux problem, the condenser tube needs to be set at an angle, which requires a large height difference or a long horizontal distance between the two devices, resulting in a larger space occupied by the distillation device. Utility Model Content

[0004] The utility model provides a distillation device, aiming to propose a new condensation structure to solve the problems of liquid reflux in the condenser tube and large space occupied by the distillation device in the background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following scheme:

[0006] The utility model provides a condensation device, which includes a heating vaporization device, a condensation part and a collection device connected in sequence; the condensation part includes a condensation tube and a condensation area, the condensation tube is divided into a first condensation tube, a second condensation tube, a third condensation tube and a fourth condensation tube, and the condensation area is wrapped in the first condensation tube; the second condensation tube is a U-shaped tube, the second condensation tube includes a vertical first tube segment, a second tube segment, and a third tube segment connecting the first tube segment and the second tube segment; the height of the second tube segment is lower than the height of the first tube segment.

[0007] Furthermore, the third pipe segment is arc-shaped.

[0008] Furthermore, a branch pipe is extended transversely from the first pipe section, and the position of the branch pipe is located above the second pipe section; the branch pipe is arranged transversely, and an air bag is provided at the end of the branch pipe.

[0009] Furthermore, the third condenser is arranged horizontally; the first condenser and the fourth condenser are arranged obliquely, and the inclination direction is gradually decreasing from left to right.

[0010] Optionally, the condensation zone is water-cooled, and the water flows from the lower right to the upper left.

[0011] Furthermore, a first valve is provided on the first condenser pipe, and the first valve is located between the heating vaporization device and the condensation area.

[0012] Furthermore, the heating vaporization device includes a tank body, and the top and bottom of the tank body are respectively provided with a top cover and a drain port; the top cover is provided with a pressure gauge, a liquid inlet interface and a steam exhaust interface; the side of the tank body is provided with a temperature gauge and a liquid level gauge.

[0013] Optionally, a flange is provided on the top of the exhaust interface.

[0014] Furthermore, the collecting device includes a box body, a condensation interface is provided on the top of the box body, and a fifth condensation tube is provided inside the box body; the fifth condensation tube is connected to the condensation part through the condensation interface.

[0015] Optionally, a flange is provided on the top of the condensation interface; and the fifth condensation tube is spiral-shaped.

[0016] Compared with the existing technology, the utility model has the following advantages:

[0017] 1. By providing a U-shaped second condenser tube in the condensation section, the condensed liquid is temporarily retained in the second condenser tube. After the accumulated liquid exceeds the height of the second tube section on the right side of the second condenser tube, it continues to flow toward the subsequent collection device to complete the collection of the condensed liquid. During this process, if there is reflux in the condenser tube, the refluxed liquid will accumulate in the second condenser tube and will not flow back into the first condenser tube and the vaporization device.

[0018] 2. A condensation zone is provided on the first condenser tube, which can accelerate the condensation of the vaporized material, thereby avoiding the problem of the condenser tube being too long caused by the air cooling process and reducing the space occupied by the entire distillation device;

[0019] 3. The condenser after the U-tube can be inclined or horizontal, which has less restrictions on the distillation device and the collection device. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] Example

[0031] Refer to the accompanying drawings, such as Figure 1-Figure 4 As shown, a distillation device comprises a heating vaporization device 1, a condensation part 2 and a collection device 3 which are connected in sequence;

[0032] Among them, Figure 2 As shown, the condensation portion 2 includes a condensation area 211 and condensation tubes, and the condensation tubes include a first condensation tube 21, a second condensation tube 22, a third condensation tube 25 and a fourth condensation tube 26 connected in sequence.

[0033] The first condenser tube 21 is tilted, with the height of the first condenser tube 21 gradually decreasing from left to right. A condensation zone 211 surrounds the first condenser tube 21. This condensation zone 211 can be water-cooled. When cold water is poured into the condensation zone 211, the water flows from the lower right to the upper left, resulting in a better condensation effect. A first valve 212 is provided on the first condenser tube 21, located between the condensation zone 211 and the heating and vaporization device 1. This valve 212 controls the timing of the vaporized liquid entering the condensation process.

[0034] The second condenser 22 is a U-shaped tube, comprising a first section 221 on the left, a second section 222 on the right, and a third section 223 in the middle. The first and second sections 221 and 222 are vertical, straight tubes, while the third section 223 is an arc-shaped tube, or it can be a horizontal, straight tube. The height of the second section 222 is less than that of the first section 221 to prevent backflow of liquid caused by excessive liquid height within the first section 221. If the liquid within the second condenser 22 exceeds the height of the second section 222, it flows through the second section 222 into the subsequent process. Existing condensers are typically straight tubes arranged at an angle, requiring a long distance during the condensation process. Furthermore, to reduce backflow, they are tilted. This requires a certain height difference between the distillation apparatus and the device that collects the condensed liquid, thus limiting the size and installation of the apparatus itself. However, with the U-shaped tube, the condenser can be tilted or horizontal, thus placing fewer restrictions on the distillation apparatus and the collection device.

[0035] A branch pipe 23 extends transversely from the first pipe section 221 and connects to the first pipe section 221. Branch pipe 23 is taller than the second pipe section 222. A balloon 24 is located at the end of branch pipe 221 and can be filled with helium. A second valve 231 is provided on branch pipe 23. After the condensation process is complete, condensed liquid remains in the second condensation pipe 22. By opening the second valve 231 and squeezing the balloon 24, the remaining condensed liquid can be pushed into the subsequent process.

[0036] The third condenser tube 25 is horizontally arranged to reduce the height of the third condenser tube 25 so as to allow the condensed liquid in the second condenser tube 22 to pass smoothly. The fourth condenser tube 26 is tilted, and the tilt direction is such that the height gradually decreases from left to right.

[0037] like Figure 3 As shown, the heating vaporization device 1 is an existing device. The heating vaporization device 1 includes a tank body 11, with a top cover 12 and a drain port 13 provided at the top and bottom of the tank body 11, respectively. The top cover 12 is provided with a pressure gauge 16, a liquid inlet port 17, and a steam exhaust port 18. A thermometer 14 and a liquid level gauge 15 are provided on the side of the tank body 11. A flange is provided at the top of the steam exhaust port 18. After the first condenser pipe 21 is inserted into the steam exhaust port 18, the two can be further secured by bolts passing through the flange.

[0038] like Figure 4 As shown, the collection device is a conventional structure. The collection device 3 includes a housing 31, with a condensation interface 32 disposed on the top of the housing 31. A fifth condensation pipe 33 is disposed within the housing 31. The fifth condensation pipe 33 is connected to the fourth condensation pipe 26 in the condensation section 2 via the condensation interface 32. A flange is disposed on the top of the condensation interface 32. The fifth condensation pipe 33 is spirally shaped, resulting in a longer length at the same height.

[0039] The above description is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
