Abstract
Description
Technical Field
[0001] This utility model belongs to the field of reboiler technology, and in particular relates to a heat pipe reboiler device. Background Technology
[0002] A heat pipe reboiler is an energy-saving heat exchange device that utilizes the efficient heat transfer characteristics of heat pipes to quickly transfer the heat provided by the external heating medium to the liquid at the bottom of the column, causing it to partially vaporize and flow back into the column to maintain the stable operation of the separation process. Traditional reboilers rely solely on reboiling heating to evaporate the solution or solvent during actual use, often without an efficient condensation structure. This results in the steam not being fully recovered and being directly emitted, which not only wastes energy but may also cause safety hazards such as excessive solvent evaporation in the experimental environment and operators inhaling harmful gases. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model provides a heat pipe reboiling device.
[0004] This invention is implemented as follows: a heat pipe reboiling device includes a reboiling tube and a steam transmission tube, the steam transmission tube being fixed to the upper part of the reboiling tube; a condenser tube, the condenser tube being disposed on one side of the reboiling tube and communicating with the reboiling tube through the steam transmission tube; and a cooling assembly, the cooling assembly including a transmission plate fixed to the upper part of the condenser tube, the transmission plate being located above the steam transmission tube and having a gap in the middle for condensing steam.
[0005] In a preferred embodiment of this invention, the condenser tube includes an outer tube and an inner tube, the transmission plate is fixed to the upper part of the inner tube, and a guide plate is fixedly connected to the output end of the transmission tube.
[0006] As a preferred embodiment of this utility model, the lower part of the diversion plate is inserted into a temporary storage box fixed on the inner wall of the inner tube, and a cooling plate is fixedly connected to the output end of the temporary storage box. The cooling plate is used to transport liquid and contact the gas transported by the steam transmission pipe for condensation.
[0007] As a preferred embodiment of this invention, a liquid transfer pipe is fixedly connected to the upper part of the condenser tube for connecting an external liquid source and transferring it to the transfer plate.
[0008] As a preferred embodiment of this utility model, a partition plate is fixedly connected inside the inner tube, and the partition plate separates the inner tube into a coolant transmission cavity and a condensate transmission cavity; the lower part of the coolant transmission cavity of the inner tube is connected to the reboiler tube through a coolant transmission pipe and a return pipe, and a condensate transmission pipe is fixedly connected to the lower part of the condensate tube of the inner tube, and the condensate transmission pipe extends through the outer tube to the outside.
[0009] As a preferred embodiment of this invention, a heat pipe frame is fixedly installed inside the reboiling tube. The heat pipe frame divides the internal space of the reboiling tube into a heating cavity. An input pipe and an output pipe are fixedly connected to the upper and lower parts of the heating cavity of the reboiling tube, respectively. The liquid is heated by the heat pipes of the heat pipe frame and steam is generated at the upper part of the reboiling tube.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention generates steam by heating the solution inside a reboiling tube. The steam is then transported upwards through a steam transmission pipe located at the top of the reboiling tube and guided to a condenser located on one side of the reboiling tube for condensation.

This not only improves reboiling efficiency but also avoids the energy waste and environmental pollution caused by direct steam discharge in traditional reboilers. At the same time, it enhances the safety and energy efficiency of the device, ensuring the green, environmentally friendly, and sustainable operation of the experimental process.

[0013] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0014] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0015] like Figures 1 to 4 As shown in the figure, the present invention provides a heat pipe reboiling device, including a reboiling tube 2 and a steam transmission tube 5, which is fixed to the upper part of the reboiling tube 2; a condenser tube 1, which is disposed on one side of the reboiling tube 2 and communicates with the reboiling tube 2 through the steam transmission tube 5; and a cooling assembly 8, which includes a transmission plate 801 fixed to the upper part of the condenser tube 1. The transmission plate 801 is located above the steam transmission tube 5 and has a gap in the middle for condensing steam.
[0016] The above-mentioned heat pipe reboiling device heats the solution in the reboiling tube 2 to generate steam. The steam is transported upward along the steam transmission pipe 5 located at the top of the reboiling tube 2 and guided to the condenser tube 1 located on one side of the reboiling tube 2 for condensation. The cooling component 8 inside the condenser tube 1 performs multi-stage diversion and cooling of the high-temperature steam entering the condenser tube 1 through the transmission plate 801 located at the top of the steam transmission pipe 5. The gap reserved in the middle of the transmission plate 801 is used to allow the steam to be evenly distributed and fully contact the cooling surface when passing through, so as to achieve efficient condensation and reflux of the steam. The condensed liquid flows back into the reboiling tube 2 to participate in reheating and evaporation, forming a continuous evaporation-condensation-reflux cycle.
[0017] In this embodiment, the condenser tube 1 includes an outer tube 101 and an inner tube 102. A transmission plate 801 is fixed on the upper part of the inner tube 102, and a guide plate 802 is fixedly connected to the output end of the transmission tube. A temporary storage box 803 is inserted into the lower part of the guide plate 802 and fixed on the inner wall of the inner tube 102. A cooling plate 804 is fixedly connected to the output end of the temporary storage box 803. The cooling plate 804 is used to transmit liquid and contact the gas transmitted by the steam transmission tube 5 for condensation. A liquid transmission tube 7 is fixedly connected to the upper part of the condenser tube 1 for connecting an external liquid source to the transmission plate 801. The condenser tube 1 consists of an outer tube 101 and an inner tube 102. After the steam is output through the steam transmission pipe 5, it first undergoes preliminary diversion and cooling through the transmission plate 801 fixed on the upper part of the inner tube 102. Subsequently, the steam comes into contact with the external coolant input from the liquid transfer pipe 7 at the upper part of the transfer plate 801 for heat exchange. After further cooling, it flows downward and is guided by the guide plate 802 at the output end of the transfer pipe, flowing into the temporary storage box 803 inserted into the inner wall of the inner tube 102. The temporary storage box 803 is used to collect and stabilize the coolant during the steam condensation process. At the same time, the cooling plate 804 fixedly connected to its output end redistributes the coolant, allowing it to be transported along the cooling plate 804 and fully contact the steam entering the condenser tube 1 for efficient condensation. The condensed liquid flows back along the wall of the inner tube 102 to the reboiler tube 2, realizing the recycling of steam and efficient heat exchange of the coolant, avoiding energy waste and improving condensation efficiency, while ensuring the continuous, stable and safe operation of the entire device, meeting the process requirements of efficient reflux and energy saving and environmental protection.
[0018] In this embodiment, a partition plate 105 is fixedly connected inside the inner tube 102. The partition plate 105 separates the inner tube 102 into a coolant transmission chamber and a condensate transmission chamber. The lower part of the coolant transmission chamber of the inner tube 102 is connected to the reboiler tube 2 through a coolant transmission pipe 103 and a return pipe 6. The lower part of the condensate in the inner tube 102 is fixedly connected to a condensate transmission pipe 104. The condensate transmission pipe 104 extends through the outer tube 101 to the outside. A heat pipe frame 9 is fixedly installed inside the reboiler tube 2. The heat pipe frame 9 separates the internal space of the reboiler tube 2 into a heating chamber. The upper and lower parts of the heating chamber of the reboiler tube 2 are respectively fixedly connected to an input pipe 3 and an output pipe 4. The liquid is heated by the heat pipes of the heat pipe frame 9 and steam is generated at the upper part of the reboiler tube 2.
[0019] The structure adopts an outer tube 101 and an inner tube 102 coaxially. After the external steam is input through the steam transmission pipe 5, it first enters the area of the transmission plate 801 fixedly installed on the upper part of the inner tube 102. The transmission plate 801 serves as the first distribution and cooling unit for condensate. The external coolant is uniformly introduced to the surface of the transmission plate 801 through the liquid transmission pipe 7 fixedly connected to the upper part of the condenser tube 1. The transmission plate 801 is used to perform preliminary cooling and guidance on the high-temperature steam entering the condenser tube 1. After cooling, the steam continues to flow along the output end of the transmission pipe, and the guide plate 802 fixedly connected to it guides some of the condensate and the incompletely condensed steam downwards. The condensate enters the temporary storage box 803, which is fixed to the inner wall of the inner tube 102. The temporary storage box 803 serves to temporarily collect and stabilize the flow rate of the condensate and the distribution of steam, ensuring good heat exchange contact between the condensate and the steam. The output end of the temporary storage box 803 is fixedly connected to a cooling plate 804. When the coolant flows over its surface, the cooling plate 804 forms a uniformly distributed liquid film or droplets, allowing the steam to continuously exchange heat with the coolant as it flows over the cooling plate 804, thereby achieving efficient condensation of the steam. Finally, the condensed liquid flows back to the reboiling tube 2 along the inner tube 102 for reuse. The uncondensed steam continues to be cooled in a controlled manner. The entire process forms a continuous and efficient evaporation-condensation-reflux closed loop, effectively improving heat exchange efficiency, reducing energy consumption and the risk of steam leakage, ensuring the safety, environmental protection and economy of the equipment operation, and meeting the strict requirements of precision processes for condensation reflux.
[0020] The working principle of this utility model: In use, the solution is heated in the reboiler tube 2 to generate steam. The steam is transported upward along the steam transmission pipe 5 located at the top of the reboiler tube 2 and guided to the condenser tube 1 located on one side of the reboiler tube 2 for condensation. The cooling component 8 inside the condenser tube 1 performs multi-stage diversion and cooling of the high-temperature steam entering the condenser tube 1 through the transmission plate 801 located at the top of the steam transmission pipe 5. The gap reserved in the middle of the transmission plate 801 is used to allow the steam to be evenly distributed and fully contact the cooling surface when passing through, so as to achieve efficient condensation and reflux of the steam. The condensed liquid flows back into the reboiler tube 2 to participate in reheating and evaporation, forming a continuous evaporation-condensation-reflux cycle.
