Description

Technical Field

[0001] This utility model relates to distillation apparatus, and more particularly to a reactive distillation apparatus, belonging to the field of reactive distillation technology. Background Technology

[0002] A reactive distillation unit is a chemical apparatus that couples a chemical reaction with a distillation separation process within the same device. It utilizes the differences in volatility of the components during distillation to allow reaction products to be separated from the reaction zone in a timely manner, thereby breaking the equilibrium constraint of the chemical reaction.

[0003] CN220404872U discloses a reaction liquid distillation apparatus, including a distillation column with a packing layer inside. An inlet pipe and an outlet pipe are located above the packing layer, while an inlet pipe and an vent pipe are located below the packing layer. A reboiler is located at the bottom of the distillation column. The inlet pipe is rotatable, with its feed end located outside the distillation column and connected to a guide pipe via a rotary joint. A drive assembly is connected to the inlet pipe outside the distillation column, and a distribution plate is connected to the discharge end of the inlet pipe inside the distillation column. A vertical rotating shaft is fixedly connected to the center of the distribution plate, penetrating the packing layer and connected to a stirring paddle. This invention features a simple and reasonable structure, easy operation, and the stirring paddle effectively agitates the reaction liquid, improving the uniformity of heating the reaction liquid by the reboiler, resulting in high distillation efficiency and good distillation effect.

[0004] However, in actual operation, this type of distillation device requires heating the reaction liquid from the bottom through a reboiler. However, the reboiler has a relatively complex structure and high maintenance costs. This method, along with heating with an external spiral heating tube, has a common drawback: it may cause uneven heating of the feed liquid in local areas, which can easily lead to local overheating, affecting the distillation reaction and the service life of the reboiler. Therefore, improvements are needed.

[0005] Therefore, a reactive distillation apparatus is proposed. Utility Model Content

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1-6 As shown, this embodiment of the present invention provides a reactive distillation apparatus, including...

[0032] The main structure includes a support frame 1, a reaction vessel 2, a top cover 3, a coupling 4, a motor A5, a main shaft 6, a stirring plate 7, a steam pipe 8, a cooling chamber 9, and a spiral condenser tube 10.

[0033] The heat equalization mechanism includes a convex plate 11, a plane bearing 12, a ceramic shell 13, a heat-conducting plate 14, a heating tube 15, a conductive slip ring 16, a carbon brush 17, a motor B18, a worm gear 19, and a worm wheel 20.

[0034] The liquid guiding mechanism includes pulley A21, pulley B22, belt 23, gear A24, rotating bearing 25, connecting plate 26, toothed ring 27, and spiral guide plate 28.

[0035] In one embodiment, the reactor 2 is fixedly installed inside the support 1, the top cover 3 is fixed to the top of the reactor 2 via a flange, the coupling 4 is fixedly installed on the top of the top cover 3, the main shaft 6 is fixedly installed on one end of the coupling 4, the motor A5 is fixedly installed on the top of the coupling 4, the main shaft 6 is connected to the output end of the motor A5 via the coupling 4, the stirring plate 7 is fixedly installed circumferentially on the surface of the main shaft 6, the steam pipe 8 is connected to the top of the top cover 3, the spiral condenser 10 is fixedly installed inside the cooling chamber 9, one end of the steam pipe 8 is connected to the spiral condenser 10, and the convex plate 11 is fixed to the reactor 2. On the surface of reactor 2, a plane bearing 12 is mounted on the surface of the convex plate 11. A ceramic shell 13 rotates on the surface of reactor 2 via the plane bearing 12. A heat-conducting plate 14 is fixedly installed inside the ceramic shell 13. A heating tube 15 is positioned between the heat-conducting plate 14 and the ceramic shell 13. A conductive slip ring 16 is fixedly installed on the surface of the ceramic shell 13. A carbon brush 17 is fixedly installed inside the support 1. A motor B18 is fixedly installed on the side of the support 1. A worm gear 19 is fixedly installed at the output end of the motor B18. A worm wheel 20 is fixedly installed on the surface of the ceramic shell 13, and the worm gear 19 meshes with the worm wheel 20. Steam enters the interior of the spiral condenser 10 through the steam pipe 8 and cools the outer wall of the spiral condenser 10 through the cooling chamber 9, thereby achieving a condensation effect.

[0036] In one embodiment, pulley A21 is fixedly mounted on the surface of the main shaft 6, pulley B22 rotates on the top of the top cover 3, belt 23 is sleeved on the surface of pulley B22, and pulley B22 is connected to pulley A21 through belt 23. Gear A24 is fixedly mounted on the bottom end of pulley B22, rotary bearing 25 is disposed on the surface of the main shaft 6, connecting plate 26 rotates on the surface of the main shaft 6 through rotary bearing 25, gear ring 27 is fixedly mounted on the top of connecting plate 26, gear ring 27 meshes with gear A24, and spiral guide plate 28 is fixedly mounted on the surface of connecting plate 26. During the rotation of stirring plate 7, under the cooperation of the transmission mechanism, connecting plate 26 and spiral guide plate 28 rotate slowly in the opposite direction along the inner wall of reactor 2. Starting motor B18 drives worm gear 19 to rotate. Under the cooperation between worm gear 19 and worm wheel 20, the ceramic shell 13, heating tube 15 and heat conduction plate 14 will rotate through plane bearing 12.

[0037] In one embodiment, the heating element 15 is spiral-shaped. The spiral shape of the heating element 15 increases resistance, thereby enabling rapid temperature increases.

[0038] In one embodiment, the heat-conducting plate 14 is made of copper. The copper heat-conducting plate 14 has excellent thermal conductivity, which allows for the efficient and rapid transfer of heat generated by the heating element 15, reducing heat loss.

[0039] In one embodiment, the conductive slip ring 16 is attached to the carbon brush 17. An external power source conducts electrical energy into the conductive slip ring 16 through the carbon brush 17, and supplies power to the heating tube 15 through the conductive slip ring 16, thereby preventing entanglement of the electrical connection between the rotating component and the stationary power source.

[0040] In one embodiment, the spiral guide plate 28 slides on the inner wall of the reactor 2. Under the combined force of the liquid and the spiral guide plate 28, some of the liquid flows upward along the spiral guide plate 28, reaching above the liquid surface and leaving some residual liquid on the inner wall of the reactor 2.

[0041] In operation, this invention works as follows: First, motor B18 is started, driving worm gear 19 to rotate. Under the cooperation of worm gear 19 and worm wheel 20, the ceramic shell 13, heating tube 15, and heat-conducting plate 14 rotate via plane bearing 12. During the rotation of the ceramic shell 13, the conductive slip ring 16 rotates. The conductive slip ring 16 remains in contact with carbon brush 17. External power is supplied to the conductive slip ring 16 through carbon brush 17, and the conductive slip ring 16 powers the heating tube 15. This prevents entanglement of the electrical connection between the rotating components and the fixed power supply. Furthermore, the heating tube 15 during rotation can evenly heat the reactor 2, reducing localized overheating problems caused by fixed heating. Next, motor A5 is started, driving the main shaft 6 to rotate via coupling 4. This causes the stirring plate 7 to rotate and stir the internal liquid. Simultaneously, the rotation of the main shaft 6 drives pulley A21 to rotate, and the belt 23... The action of the pulley B22 and the gear A24 below will drive them to rotate together. Then, under the meshing action between the gear A24 and the gear ring 27, the connecting plate 26 and the spiral guide plate 28 will rotate. At the same time, their rotation direction is opposite to the rotation direction of the main shaft 6, so that the flow direction of the internal liquid is opposite to that of the spiral guide plate 28. Under the action of the liquid and the spiral guide plate 28, some liquid will flow upward along the spiral guide plate 28, reaching the liquid surface and leaving some residual liquid on the inner wall of the reactor 2. At this time, under the action of the heating tube 15, the temperature of the inner wall of the reactor 2 will rise, which will first heat the residual liquid above the liquid surface in the reactor 2 and generate steam. This improves the distillation efficiency and does not require waiting for the liquid inside the reactor 2 to reach the boiling point before steam appears. The steam enters the interior of the spiral condenser 10 through the steam pipe 8 and cools the outer wall of the spiral condenser 10 through the cooling chamber 9, thereby achieving the condensation effect.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
