Description
Technical Field
[0001] This utility model relates to the field of distillation column technology, specifically a split-type energy-saving distillation column. Background Technology
[0002] Distillation is a unit operation process that separates components in a mixture by utilizing their different volatility. In a distillation column, the mixture is heated to partial vaporization, and the resulting vapor rises and undergoes mass and heat transfer with the liquid refluxed from the top of the column on the trays or packing. This process enriches the more volatile components in the vapor and the less volatile components in the liquid. Through multiple partial vaporizations and partial condensations, the mixture is finally separated with high purity.
[0003] A distillation column is a tower-type gas-liquid contact device used for distillation. The components in a mixture have different volatility and different vapor pressures at the same temperature. Based on this characteristic, the lighter components in the liquid phase can enter the gas phase, and the heavier components in the gas phase can enter the liquid phase, thus separating the mixture. Packed distillation columns need to be inspected and the packing replaced regularly during use.
[0004] Existing distillation columns are cumbersome and time-consuming to disassemble, clean, replace packing materials, or inspect and replace. Therefore, a split-type energy-saving distillation column is proposed to address these issues. Utility Model Content

[0010] Preferably, the second pipe sidewall is fixed with an insulation layer; the insulation layer is correspondingly arranged with the second pipe; the insulation layer can effectively prevent heat from dissipating to the surroundings through the inner wall of the first pipe, so that the heat in the first pipe can be retained, reducing heat loss and improving the energy utilization efficiency of the heat flow into the first sleeve.
[0011] Preferably, multiple sets of cleaning rings are fixed to the top of the fixing plate; the cleaning rings are located in the middle of the fixing plate; the cleaning rings are arranged correspondingly to the screws; when the contaminants on the surface of the screws are cleaned by the cleaning rings, the contaminants on the surface of the screws can be reduced from entering the interior of the fixing plate, which would cause abnormal noises and jamming during screw disassembly, and keep the surface of the screws clean.

[0023] Specific implementation examples are given below.
[0024] like Figures 1 to 5As shown in the embodiment of this utility model, a split-type energy-saving distillation column includes a workbench 1; a first sleeve 11 is fixedly connected to the top of the workbench 1; a second sleeve 12 is fixedly connected to the top of the first sleeve 11; a third sleeve 13 is fixedly connected to the top of the second sleeve 12; a pair of fixing plates 17 are fixedly connected to the middle of the first sleeve 11 and the second sleeve 12; a pair of fixing plates 17 are fixedly connected to the middle of the second sleeve 12 and the third sleeve 13; a screw 18 is threadedly connected to the top of the fixing plate 17; a first pipe 14 is fixedly connected to the side wall of the third sleeve 13; a second pipe 15 is fixedly connected to the side wall of the second sleeve 12; a first pipe 14 is fixedly connected to the side wall of the first sleeve 11; a second pipe 15 is fixedly connected to the side wall of the first sleeve 11; a third pipe 15 is fixedly connected to the side wall of the second sleeve 12; a fourth pipe 15 is fixedly connected to the side wall of the third sleeve 13; a fifth pipe 15 is fixedly connected to the side wall of the second sleeve 12; a sixth pipe 15 is fixedly connected to the side wall of the first sleeve 11; a seventh pipe 15 is fixedly connected to the side wall of the second sleeve 12; a fifth pipe 15 is fixedly connected to the side wall of the third sleeve 13; a seventh pipe 15 is fixedly connected to the side wall of the second sleeve 12; a fifth pipe 15 is fixedly connected to the side wall of the third sleeve 13; a sixth pipe 15 is fixedly connected to the side wall of the second sleeve 12; a seventh pipe 15 is fixedly connected to the side wall of the second sleeve 12; a seventh pipe 15 is fixedly connected to the side wall of the second sleeve 12; a seventh pipe 15 is fixed There is a third pipe 16; the first pipe 14 and the second pipe 15 are correspondingly arranged; the second pipe 15 and the third pipe 16 are correspondingly arranged; during operation, the high temperature of the distillation inside the third sleeve 13 can flow into the first pipe 14, flow into the second pipe 15 and the third pipe 16, and return to the first sleeve 11. The screws 18 at the bottom of the third sleeve 13 are rotated and threaded onto the fixing plate 17. Removing these screws allows the third sleeve 13 to be removed. Similarly, rotating the screws 18 at the bottom of the second sleeve 12 removes the screws 18, allowing the second sleeve 12 to be removed. 2. Remove the first sleeve 11 from the top and fill or clean the inside of the first sleeve 11. After cleaning, place the second sleeve 12 on top of the first sleeve 11 and install the removed screws 18. Align the second pipe 15 on the side wall of the second sleeve 12 with the top of the third pipe 16 to install the second sleeve 12 on top of the first sleeve 11. After the second sleeve 12 is installed on top of the first sleeve 11, place the third sleeve 13 on top of the second sleeve 12 and fix it with multiple sets of screws 18 to fix the third sleeve 13 on top of the fixing plate 17. Connect the first sleeve 11 and the second sleeve 16 with multiple sets of screws 18 in the middle of the fixing plate 17. The second sleeve 12 is used for packing inside the distillation column. When it needs to be replaced due to blockage or cleaning, each layer of the distillation column can be disassembled separately by screws 18 and screws 18 connected to the fixing plate 17. This allows for more direct and convenient disassembly, enabling specific parts to be packed or cleaned, reducing large-scale disassembly of the column body and reducing maintenance time. The first pipe 14 transfers the high-temperature heat inside the third sleeve 13 to the inside of the first sleeve 11, increasing the recycling of heat, reducing the heating load of the first sleeve 11, reducing energy consumption, improving the thermal efficiency of the entire distillation system, reducing heat waste, and making full use of heat, which helps to improve the economy and environmental protection of the distillation process.
[0025] like Figures 1 to 2As shown, a container 2 is fixedly connected to the side wall of the second sleeve 12; multiple sets of heating rods 24 are fixedly connected to the middle of the second sleeve 12 and the container 2; a water pump 23 is fixedly connected to the side wall of the container 2; an inlet 21 is fixedly connected to the side wall of the third sleeve 13; an outlet 22 is fixedly connected to the side wall of the water pump 23; the inlet 21 and the outlet 22 are connected to the inside of the container 2; during operation, when distillation is carried out inside the second sleeve 12, liquid is injected into the container 2, and the heating rods 24 heat the liquid inside the container 2. After the liquid inside the container 2 is heated, the inlet 21 is activated to draw in the liquid inside the container 2 and discharge it from the middle of the outlet 22. The liquid discharged from the outlet 22 continues to flow into the container 2. Through the circulation of the liquid inside the container 2 along the side wall of the second sleeve 12 column, the heat is transferred more evenly in the column, providing a stable temperature environment for the distillation process. This is beneficial for the second sleeve 12 to carry out more sufficient heat transfer, thereby improving the separation effect of the distillation column and increasing the purity of the distillation.
[0026] like Figure 1 and Figure 3 As shown, a clamping plate 31 is fixedly connected to the bottom end of the first pipe 14; a groove 3 is fixedly connected to the top end of the second pipe 15; a clamping plate 31 is fixedly connected to the bottom end of the second pipe 15; a groove 3 is fixedly connected to the top end of the third pipe 16; the conveying groove 3 is correspondingly set with the clamping plate 31; during operation, when the first pipe 14 and the second pipe 15 are disassembled and assembled, the clamping plate 31 below the first pipe 14 can be embedded into the groove 3 at the top end of the second pipe 15, so that the third sleeve 13 and the second sleeve 12 are installed in the designated position during disassembly and assembly. Through the cooperation of the groove 3 and the clamping plate 31, the first pipe 14 and the second pipe 15 are combined to ensure good sealing at the connection between the first pipe 14 and the second pipe 15, and also facilitate the disassembly and connection of the first pipe 14 and the second pipe 15, and efficient installation by aligning the groove 3 and the clamping plate 31.
[0027] like Figure 5 As shown, a first sealing gasket 4 is fixedly connected to the bottom end of the fixed plate 17; the first sealing gasket 4 is disposed in the middle of the fixed plate 17; during operation, when a pair of fixed plates 17 are combined, the first sealing gasket 4 can further seal the middle of the fixed plate 17. Through the good sealing of the first sealing gasket 4, the sealing of the first sleeve 11 and the second sleeve 12 during distillation can be reduced, leakage during distillation can be reduced, and a stable gas-liquid balance can be maintained.
[0028] like Figure 3As shown, a heat insulation layer 5 is fixed to the side wall of the second pipe 15; the heat insulation layer 5 is correspondingly arranged with the second pipe 15; during operation, the higher temperature inside the third sleeve 13 flows into the first pipe 14, and the high temperature gas is cooled during the flow into the first pipe 14. The heat insulation layer 5 can protect the airflow inside the first pipe 14. The heat insulation layer 5 can effectively prevent heat from dissipating to the surroundings through the inner wall of the first pipe 14, so that the heat inside the first pipe 14 can be retained, reducing heat loss and improving the energy utilization efficiency of the heat flow inside the first pipe 14 flowing into the first sleeve 11.
[0029] like Figure 4 As shown, multiple sets of cleaning rings 6 are fixed to the top of the fixing plate 17; the cleaning rings 6 are located in the middle of the fixing plate 17; the cleaning rings 6 are correspondingly arranged with the screws 18; during operation, when the multiple sets of screws 18 are rotated, the sidewalls of the screws 18 contact the cleaning rings 6, cleaning the contaminants on the surface of the screws 18. When the contaminants on the surface of the screws 18 are cleaned by the cleaning rings 6, it can reduce the contaminants on the surface of the screws 18 from entering the interior of the fixing plate 17, which would cause the screws 18 to make abnormal noises when disassembling and cause rotation jamming problems, thus keeping the surface of the screws 18 clean.
[0030] Working principle: The high temperature of the distillation inside the third sleeve 13 flows into the first pipe 14, then into the second pipe 15 and the third pipe 16, and finally back into the first sleeve 11. The screws 18 at the bottom of the third sleeve 13 are threaded onto the fixing plate 17. Removing these screws allows the third sleeve 13 to be removed. Similarly, the screws 18 at the bottom of the second sleeve 12 are removed, allowing the second sleeve 12 to be removed. Remove the first sleeve 11 from the top and fill or clean the inside of the first sleeve 11. After cleaning, place the second sleeve 12 on top of the first sleeve 11 and install the removed screws 18. Align the second pipe 15 on the side wall of the second sleeve 12 with the top of the third pipe 16 to install the second sleeve 12 on top of the first sleeve 11. After the second sleeve 12 is installed on top of the first sleeve 11, place the third sleeve 13 on top of the second sleeve 12 and secure it with multiple sets of screws 18. The third sleeve 13 is fixed above the fixing plate 17. When the second sleeve 12 is distilling, liquid is injected into the container 2. The heating rod 24 heats the liquid inside the container 2. After the liquid inside the container 2 is heated, the inlet 21 is activated to draw in the liquid inside the container 2 and discharge it from the middle of the outlet 22. The liquid discharged from the outlet 22 continues to flow into the container 2. When the first pipe 14 and the second pipe 15 are disassembled and assembled, the clamping plate 31 below the first pipe 14 can be embedded into the groove 3 at the top of the second pipe 15, so that the third sleeve 13 and the second sleeve 12 are installed in the designated position during disassembly and assembly. When the pair of fixing plates 17 are combined, the first sealing gasket 4 can further seal the middle of the fixing plate 17. The high temperature inside the third sleeve 13 flows into the first pipe 14. The high temperature gas is cooled during the flow into the first pipe 14. The insulation layer 5 can protect the airflow inside the first pipe 14. When the multiple sets of screws 18 are rotated, the side wall of the screw 18 contacts the cleaning ring 6 to clean the contamination on the surface of the screw 18.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
