Description

Technical Field

[0001] The utility model relates to the field of distillation columns, and more specifically, to a multi-stage separation distillation column. Background Art

[0002] There are two main types of distillation columns: plate columns and packed columns. The distillation column utilizes the property that each component in the mixture has different volatilities, that is, the vapor pressures of each component are different at the same temperature, so that the light components (low boilers) in the liquid phase are transferred to the gas phase, while the heavy components (high boilers) in the gas phase are transferred to the liquid phase, thereby achieving the purpose of separation. The distillation column is also a mass transfer and heat transfer device widely used in petrochemical production.

[0003] When multiple multi-stage tower bodies are installed and used in a stacked manner, a number of fixing bolts need to be provided outside the connecting ring of adjacent multi-stage tower bodies to connect them. During the connection, the connection part of the multi-stage tower bodies can be sealed and protected. However, after the sealing part is used for a period of time, there may be a risk of poor sealing or even leakage. If the connectivity of the connecting ring deteriorates and is not discovered in time, it will affect the processing quality of the gas and liquid in the multi-stage tower body. Therefore, it is necessary to design a multi-stage separation distillation column with a connection point detection function to solve the above problems. Summary of the Utility Model

[0004] 1. Technical Problems to be Solved

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a multi-stage separation distillation column. In this solution, the U-shaped detection block moves circumferentially on the outer ring of the connecting ring. During the movement, the detection sensor in the U-shaped detection block can sense the gas transmitted between the two connecting rings, and timely remind the staff to come for maintenance of the connection point, thereby ensuring the processing quality of the gas and liquid in the multi-stage tower body.

[0006] 2. Technical Solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A multi-stage separation distillation column includes a reaction kettle, and a plurality of multi-stage tower bodies are installed at the upper end of the reaction kettle. The plurality of multi-stage tower bodies are arranged equidistantly from top to bottom. One end of each adjacent multi-stage tower body is fixedly connected with a connecting ring. An outer ring is fixedly connected to the outer end of the multi-stage tower body. The outer ring is located directly below the connecting ring. An annular electric guide rail is fixedly connected to the upper end of the outer ring. The output end of the annular electric guide rail is fixedly connected with a vertical rotating rod. The upper end of the vertical rotating rod is fixedly connected with a U-shaped detection block, and a detection sensor is fixedly connected to the inner side wall of the U-shaped detection block.

[0009] Further, a plurality of fixing bolts are installed on the outer sides between the corresponding two connecting ring loops, and the plurality of fixing bolts are arranged at equal intervals in a ring shape.

[0010] Further, the U-shaped detection block is located outside the corresponding two connecting ring loops.

[0011] Further, a protective mesh cover is arranged at the outer end of the detection inductor, and the position between the protective mesh cover and the two connecting ring loops is matched with each other.

[0012] Further, an internal vertical shaft is installed between the upper and lower inner walls of the U-shaped detection block, and the internal vertical shaft is located on the side of the protective mesh cover.

[0014] Further, a thickened base is fixedly connected to the lower end of the reaction kettle, and a visual panel is fixedly connected to the upper end of the reaction kettle.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present utility model are as follows:

[0017] (1) In this solution, a U-shaped detection block is arranged outside the corresponding two connecting ring loops. The U-shaped detection block is connected to the annular electric guide rail on the outer ring through a vertical rotating rod. The U-shaped detection block moves circumferentially on the outer ring of the connecting ring loop. During the displacement process, the detection inductor in the U-shaped detection block can sense the gas transmitted between the two connecting ring loops, timely reminding the staff to come for maintenance of the connection point, thereby ensuring the processing quality of gas-liquid in the multi-stage tower body. Moreover, the protective mesh cover outside the detection inductor can protect the detection inductor, which is beneficial to ensuring the service life of the detection inductor.

[0018] (2) At the same time, an internal vertical shaft can be arranged in cooperation between the detection inductor and the connecting ring loop. The contact rotation shaft rotatably connected to the outside of the internal vertical shaft can be in contact with the outer side wall of the connecting ring loop when the U-shaped detection block moves circumferentially, so that a more comprehensive contact position can be generated between the U-shaped detection block and the connecting ring loop, making the circumferential movement process of the U-shaped detection block more stable and the monitoring position of the detection inductor more stable.

[0028] Embodiment:

[0029] Please refer to Figures 1-4, a multi-stage separation rectification tower, including a reaction kettle 1. A plurality of multi-stage tower bodies 3 are installed at the upper end of the reaction kettle 1. The plurality of multi-stage tower bodies 3 are arranged at equal distances from top to bottom. One end of each adjacent multi-stage tower body 3 is fixedly connected with a connecting ring 4. An outer ring 5 is fixedly connected to the outer end of the multi-stage tower body 3. The outer ring 5 is directly below the connecting ring 4. An annular electric guide rail 6 is fixedly connected to the upper end of the outer ring 5. The output end of the annular electric guide rail 6 is fixedly connected with a vertical rotating rod 7. The upper end of the vertical rotating rod 7 is fixedly connected with a U-shaped detection block 8. A detection sensor 9 is fixedly connected to the inner side wall of the U-shaped detection block 8.

[0030] Please refer to Figures 1-4 , a plurality of fixing bolts 13 are installed on the outer side between two corresponding connecting rings 4. The plurality of fixing bolts 13 are arranged at equal distances in a ring shape. The U-shaped detection block 8 is located on the outer side of two corresponding connecting rings 4. A protective mesh cover 10 is arranged at the outer end of the detection sensor 9. The position of the protective mesh cover 10 is matched with the position between the two connecting rings 4. An internal vertical shaft 11 is installed between the upper and lower inner walls of the U-shaped detection block 8. The internal vertical shaft 11 is located on the side of the protective mesh cover 10. The outer end of the internal vertical shaft 11 is rotatably connected with an abutting rotating shaft 12. The abutting rotating shaft 12 is in contact with the outer side wall of the connecting ring 4. A thickened base 14 is fixedly connected to the lower end of the reaction kettle 1. A visual panel 2 is fixedly connected to the upper end of the reaction kettle 1.

[0031] Please refer to Figures 1-4, in this solution, when multiple multi-stage towers 3 are stacked and installed for use, a number of fixing bolts 13 need to be set outside the connecting ring 4 of adjacent multi-stage towers 3 to connect them. During the connection, the connection part of the multi-stage tower 3 can be sealed and protected. However, after the sealing element in the protection process has been used for a period of time, there may be a risk of poor sealing or even leakage. If the connectivity of the connecting ring 4 deteriorates and is not discovered in time, it will affect the processing quality of the gas and liquid in the multi-stage tower 3. Therefore, U-shaped detection blocks 8 are set outside the corresponding two connecting rings 4. The U-shaped detection blocks 8 are connected to the annular electric guide rail 6 on the outer ring 5 through the vertical rotating rod 7. The U-shaped detection blocks 8 move circumferentially outside the connecting ring 4. During the displacement process, the detection sensor 9 in the U-shaped detection block 8 can sense the gas transmitted between the two connecting rings 4. If the sealing between the two connecting rings 4 is in a normal state, the detection sensor 9 will not give an alarm. If there is a problem with the sealing between the two connecting rings 4, the detection sensor 9 will send an alarm signal to the staff through the external control terminal, reminding the staff to come and repair the connection point, thereby ensuring the processing quality of the gas and liquid in the multi-stage tower 3. Moreover, the protective mesh cover 10 outside the detection sensor 9 can protect the detection sensor 9, which is beneficial to ensuring the service life of the detection sensor 9. At the same time, an internal vertical shaft 11 can be cooperatively arranged between the detection sensor 9 and the connecting ring 4. The abutting rotating shaft 12 rotatably connected to the outside of the internal vertical shaft 11 can contact the outer side wall of the connecting ring 4 when the U-shaped detection block 8 moves circumferentially, so that a more comprehensive contact position can be generated between the U-shaped detection block 8 and the connecting ring 4, making the circumferential movement process of the U-shaped detection block 8 more stable and the monitoring position of the detection sensor 9 more stable.

[0032] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
