[0006] The condensation and distillation system according to the embodiment of the present invention has at least the following beneficial effects: when various solvents react in the kettle, volatile gases will be generated. The volatile gases will enter the first condensation tower through the first connection part and contact the inner wall of the first condensation tower to condense. The condensed liquid solvent will flow to the second connection part below under the action of its own weight and flow back into the kettle through the second connection part. Among them, the second condensation tower will be able to receive part of the volatile gas that has not come into contact with the inner wall of the first condensation tower, and condense the gas through the inner wall of the second condensation tower. The condensed liquid container will flow from the second condensation tower back to the first condensation tower. Therefore, the first condensation tower will cooperate with the second condensation tower to perform the condensation operation synchronously, thereby effectively increasing the operating efficiency of the condensation operation.

[0007] Since the first condensation tower extends in the height direction of the kettle body and overlaps with the kettle body, and the second condensation tower surrounds the kettle body, the first condensation tower and the second condensation tower will be close to the kettle body in spatial position and overlap with the kettle body in multiple directions, thereby effectively reducing the outward extension of the first condensation tower and the second condensation tower relative to the kettle body, thereby reducing the overall extension area and correspondingly achieving the purpose of reducing space requirements.

[0008] According to some embodiments of the present invention, the second condensation tower gradually bends and extends upward in a direction away from the first condensation tower.

[0016] The reactor according to the second embodiment of the present invention includes the condensation and distillation system according to the first embodiment of the present invention.

[0017] The reactor according to the embodiment of the present invention has at least the following beneficial effects: when various solvents react in the reactor body, volatile gases will be generated. The volatile gases will enter the first condensation tower through the first connection part and contact the inner wall of the first condensation tower to condense. The condensed liquid solvent will flow to the second connection part below under the action of its own weight and flow back into the reactor body through the second connection part. Among them, the second condensation tower will be able to receive some of the volatile gases that have not come into contact with the inner wall of the first condensation tower, and condense the gas through the inner wall of the second condensation tower. The condensed liquid container will flow from the second condensation tower back to the first condensation tower. Therefore, the first condensation tower will cooperate with the second condensation tower to perform the condensation operation synchronously, thereby effectively increasing the operating efficiency of the condensation operation.

[0018] Since the first condensation tower extends in the height direction of the kettle body and overlaps with the kettle body, and the second condensation tower surrounds the kettle body, the first condensation tower and the second condensation tower will be close to the kettle body in spatial position and overlap with the kettle body in multiple directions, thereby effectively reducing the outward extension of the first condensation tower and the second condensation tower relative to the kettle body, thereby reducing the overall extension area and correspondingly achieving the purpose of reducing space requirements.

[0029] Reference Figure 1A condensation distillation system includes: a kettle 100, a first condensation tower 510, and a second condensation tower 520. The kettle 100 is provided with a stirring device 800. The first condensation tower 510 is mounted on the side of the kettle 100 and connected to the kettle 100. The first condensation tower 510 has a first connection portion 519 and a second connection portion 518, which are located at different heights and both communicate with the kettle 100. The first condensation tower 510 extends along the height direction of the kettle 100 and overlaps with the kettle 100. The second condensation tower 520 is connected to the first condensation tower 510 and communicates with its upper portion. The second condensation tower 520 is an arc-shaped curved pipe and is arranged around the kettle 100. The end of the second condensation tower 520 away from the first condensation tower 510 is connected to an exhaust gas exhaust pipe 525. When various solvents react in the kettle 100, volatile gases will be generated. The volatile gas will enter the first condensation tower 510 through the first connection portion 519 and contact the inner wall of the first condensation tower 510, thereby condensing. The condensed liquid solvent will flow to the second connection portion 518 below under the action of its own weight, and then flow back into the kettle body 100 from the second connection portion 518. Among them, the second condensation tower 520 will receive some of the volatile gas that has not contacted the inner wall of the first condensation tower 510 and condense this gas through the inner wall of the second condensation tower 520. The condensed liquid solvent will flow from the second condensation tower 520 back into the first condensation tower 510. Therefore, the first condensation tower 510 and the second condensation tower 520 will cooperate together to perform the condensation operation synchronously, thereby effectively increasing the efficiency of the condensation operation. Since the first condensation tower 510 extends in the height direction of the kettle body 100 and overlaps with the kettle body 100, and the second condensation tower 520 surrounds the kettle body 100, the first condensation tower 510 and the second condensation tower 520 will be close to the kettle body 100 in terms of spatial position and overlap with the kettle body 100 in multiple directions, thereby effectively reducing the outward extension of the first condensation tower 510 and the second condensation tower 520 relative to the kettle body 100, thereby achieving the reduction of the overall extension area and correspondingly achieving the purpose of reducing space requirements.

[0030] Specifically, the stirring device 800 includes a motor and a connected stirring paddle. The motor is located outside the kettle body 100, and the stirring paddle extends into the kettle body 100 and rotates and stirs the kettle body 100. Of course, the stirring device 800 can also be composed of other components, such as a screw, whose threaded blades provide stirring. The specific implementation method can be adjusted accordingly according to actual needs and is not limited here.

[0031] In certain embodiments, reference Figure 2The second condensation tower 520 gradually bends and extends upward in a direction away from the first condensation tower 510. Since the second condensation tower 520 extends upward, the volatile gas condenses into a liquid solvent after contacting the inner wall of the second condensation tower 520, and the liquid solvent flows back to the bottom of the second condensation tower 520 under the action of its own weight. Therefore, the liquid solvent can be automatically refluxed, thereby smoothly achieving the purpose of solvent recovery.

[0032] It is conceivable that the second condensation tower 520 can also be arranged horizontally around the kettle body 100, and achieve the reflux effect of the solvent through negative pressure adsorption and other methods. The specific implementation method can be adjusted accordingly according to actual needs and is not limited here.

[0033] In certain embodiments, reference Figure 2 The second condensation tower 520 spirally extends toward the top of the kettle body 100, with the exhaust gas exhaust pipe 525 connected to the top of the second condensation tower 520. This spiral extension maximizes the length of the second condensation pipe, thereby increasing the flow path of the volatile gases and thereby increasing the amount of volatile gas condensed. The extension direction of the second condensation tower 520 allows the exhaust gas exhaust pipe 525 to be elevated as much as possible relative to the first condensation tower 510, thereby effectively ensuring that the volatile gases are condensed as much as possible within the second condensation tower 520 and increasing the amount of volatile gas recovered.

[0034] In certain embodiments, reference Figure 2 The exhaust gas discharge pipe 525 is tilted in a direction away from the kettle body 100. The tilt of the exhaust gas discharge pipe 525 allows the gas to be ejected from the exhaust gas discharge pipe 525 in a direction away from the kettle body 100, thereby minimizing the impact of the exhaust gas on the kettle body 100 when the connection between the exhaust gas discharge pipe 525 and other pipelines is damaged.

[0035] In certain embodiments, reference Figure 2 The exhaust gas exhaust pipe 525 extends upward from the end of the second condensation tower 520, with the outlet of the exhaust gas exhaust pipe 525 facing upward. The upward-facing exhaust gas exhaust pipe can guide the volatile gas to be ejected above the second condensation tower 520, thereby effectively increasing the height difference between the volatile gas and the second condensation tower 520, thereby smoothly separating the condensed liquid solvent and the volatile gas by the solvent's own weight.

[0036] In certain embodiments, referring to the figures, a first connecting pipe 540 and a second connecting pipe 570 are disposed between the first condensation tower 510 and the second condensation tower 520. The first condensation tower 510 and the second condensation tower 520 are interconnected via the first connecting pipe 540. The second connecting pipe 570 is connected to the bottom end of the second condensation tower 520 and communicates with the exterior of the second condensation tower 520. Volatile gases within the first condensation tower 510 can enter the second condensation tower 520 through the first connecting pipe 540, thereby allowing the first condensation tower 510 and the second condensation tower 520 to condense the volatile gases simultaneously, thereby increasing the condensation efficiency of the volatile gases. After the volatile gases within the second condensation tower 520 are condensed into a liquid solvent, the liquid solvent will flow to the bottom of the second condensation tower 520 under the action of its own weight. Since the first connecting pipe 540 is located at the upper half of the end of the second condensation tower 520, and the second connecting pipe 570 is connected to the lower half of the end of the second condensation tower 520, the volatile gas entering the second condensation tower 520 and the liquid solvent leaving the second condensation tower 520 will be automatically distinguished, thereby avoiding mutual influence and turbulence problems between the two.

[0037] In certain embodiments, reference Figure 3 The first connecting pipe 540 has a bend section 545 in the middle, and both ends of the first connecting pipe 540 have turning points between the bend section 545 and the first connecting pipe 540. The bend section 545 not only effectively increases the flow path of the volatile gas between the first condensation tower 510 and the second condensation tower 520, but also creates collision points for the volatile gas through multiple turning points. The longer flow path and more collision points effectively increase the condensation effect of the volatile gas, thereby improving the condensation efficiency of the volatile gas.

[0038] Specifically, the middle portion of the first connecting tube 540 is bent three times, each time by 90 degrees. Of course, the first connecting tube 540 can also be bent more times. The specific implementation method can be adjusted accordingly according to actual needs and is not limited here.

[0039] In certain embodiments, reference Figure 3 The first connecting pipe 540 and the second connecting pipe 570 are both connected to the same end of the second condensing tower 520, wherein the first connecting pipe 540 is located above the second connecting pipe 570. The positional relationship between the first connecting pipe 540 and the second connecting pipe 570 allows the volatile gas at the first connecting pipe 540 and the liquid solvent at the second connecting pipe 570 to have a divided flow area due to different dead weights, thereby avoiding mutual interference and turbulence between the two, thereby ensuring the smooth progress of the overall condensation operation.

[0040] In certain embodiments, reference Figure 2The bottom of the first condensation tower 510 is provided with a temperature-isolating section 512, and the temperature-isolating section 512 is provided with a discharge port 514. When the contents of the first condensation tower 510 are condensed, in addition to producing fluid, solid powder may also be produced. The solid powder will fall to the bottom of the first condensation tower 510 under the action of its own weight and be discharged from the discharge port 514. The temperature-isolating section 512 can prevent the temperature inside the first condensation tower 510 from affecting its exterior, thereby effectively avoiding the problem of workers being injured due to high temperature when receiving materials at the discharge port 514.

[0041] A second aspect of the present invention provides an embodiment of a reactor, comprising the above-mentioned condensation and distillation system. When various solvents react within the reactor body 100, volatile gases are generated. The volatile gases enter the first condensation tower 510 through the first connection portion 519 and contact the inner wall of the first condensation tower 510, thereby condensing. The condensed liquid solvent will flow to the second connection portion 518 below under the action of its own weight and flow back into the reactor body 100 from the second connection portion 518. Among them, the second condensation tower 520 will receive some of the volatile gases that have not contacted the inner wall of the first condensation tower 510 and condense the gases through the inner wall of the second condensation tower 520. The condensed liquid container will flow from the second condensation tower 520 back into the first condensation tower 510. Therefore, the first condensation tower 510 will cooperate with the second condensation tower 520 to perform the condensation operation simultaneously, thereby effectively increasing the efficiency of the condensation operation. Since the first condensation tower 510 extends in the height direction of the kettle body 100 and overlaps with the kettle body 100, and the second condensation tower 520 surrounds the kettle body 100, the first condensation tower 510 and the second condensation tower 520 will be close to the kettle body 100 in terms of spatial position and overlap with the kettle body 100 in multiple directions, thereby effectively reducing the outward extension of the first condensation tower 510 and the second condensation tower 520 relative to the kettle body 100, thereby achieving the reduction of the overall extension area and correspondingly achieving the purpose of reducing space requirements.

[0042] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
