Description

Technical Field

[0001] The invention relates to the technical field of tubular condensers, in particular to a tubular condenser used in a methanedisulfonic acid extraction process. Background Art

[0002] Methanedisulfonic acid, as an important organic synthesis intermediate and highly efficient catalyst, is widely used in the modern chemical industry. The industry typically employs a sulfonation process involving fuming sulfuric acid and dichloromethane, followed by multi-stage purification and concentration steps to obtain a high-purity product. However, during the sulfonation process, dichloromethane is often used in excess to ensure complete reaction. In this case, the post-reaction mixture is transferred to a still, where the residual dichloromethane is vaporized by heating. The vapor is then directed to a tubular condenser, where heat exchange liquefies the gaseous dichloromethane, thereby reducing raw material waste.

[0003] Tubular condensers commonly used in the industrial sector often adopt a fixed tubesheet design. Their core structure comprises a pressure shell, heat transfer tube bundle, fixed tubesheet, and header. The tube bundle consists of multiple parallel metal condenser tubes (mostly made of stainless steel, though titanium alloy is used for corrosive environments). Both ends are rigidly secured to the fixed tubesheet via welding or expansion joints. During normal operation, a tubular condenser requires a water pump to transport condensate into the tubes, thereby exchanging heat with the hot air within the shell. The condensate can also be directed to other locations after heat exchange, recycling its waste heat to achieve energy conservation and emission reduction.

[0004] During normal use, the condenser tube will be blocked due to the influence of internal scale. When the condenser tube is blocked, it will significantly increase the energy consumption of the water pump and even cause the water pump to malfunction. Therefore, the inside of the condenser tube needs to be cleaned regularly. When the condenser tube is seriously blocked, in order to reduce the impact on the energy consumption of the water pump and ensure the condensation efficiency, the severely blocked condenser tube needs to be replaced. When a single condenser tube needs to be replaced, it is necessary to use a tool to cut the condenser tube. After the condenser tube is pulled out, the residue in the fixed tube plate hole needs to be cleaned. Only then can the new condenser tube be inserted into the fixed tube plate and re-fixed to the fixed tube plate by welding or expansion. When all heat transfer tubes need to be replaced, the above-mentioned single replacement operation must be repeated for disassembly and installation, resulting in a long overall process. Therefore, a long period of downtime is required, resulting in a reduced dichloromethane recovery rate. Summary of the Invention

[0022] Example 1

[0023] A tubular condenser for use in the extraction process of methanedisulfonic acid, such as Figure 1-Figure 5The condensing shell 1 is shown as follows, comprising a condensing shell 1, which is composed of an upper and lower part, and the upper and lower parts of the condensing shell 1 are connected by multiple bolts, and an air inlet and a liquid outlet are respectively provided on the upper and lower sides of the condensing shell 1, and a diverter shell 2 is detachably connected to one side of the condensing shell 1, and two cavities symmetrically distributed up and down are provided in the diverter shell 2, and the diverter shell 2 is provided with an upper and lower ports, which are respectively communicated with adjacent cavities in the diverter shell 2, and condensed water flows in from the upper port of the diverter shell 2 and flows out from its lower port, and a fixed shell 3 is detachably connected to the other side of the condensing shell 1, and the fixed shell 3 is used to guide the condensed water, and two fixed plates 4 symmetrically distributed on the left and right are detachably connected in the condensing shell 1, and the air inlet and the liquid outlet on the condensing shell 1 are both located between the two fixed plates 4, and a rubber pad that increases the sealing between the condensing shell 1 and the adjacent fixed plates 4 is provided, and a connecting shell 5 is detachably connected to the condensing shell 1, and a connecting shell 5 is detachably connected to the condensing shell 1. There is a gap between the upper and lower sides of the shell 5 and the inner wall of the condensation shell 1 for the circulation of hot air. The connecting shell 5 is provided with two storage cavities symmetrically distributed in the upper and lower parts. Several condensing tubes 6 are provided between the connecting shell 5 and the symmetrically distributed fixed plate 4. The specific number of condensing tubes 6 can be selected by the staff, but it is necessary to control the number of condensing tubes 6 between each fixed plate 4 and the connecting shell 5 to be equal. The fixed plate 4 is detachably connected to two first movable plates 7 symmetrically distributed in the upper and lower parts. The first movable plate 7 and the adjacent fixed plate 4 can be fixed by bolts. Two second movable plates 8 symmetrically distributed in the left and right parts are detachably connected in the storage cavity of the connecting shell 5. The second movable plate 8 and the connecting shell 5 can be fixed by bolts. Several reaming parts 9 are slidably connected to the first movable plate 7 and the second movable plate 8. The number of reaming parts 9 is twice the number of condensing tubes 6. The reaming parts 9 are used to expand the ports of adjacent condensing tubes 6.

[0024] like Figure 6 As shown, an inclined annular surface is provided on the side of the reaming member 9 close to the adjacent condenser tube 6, and the minimum diameter of the inclined annular surface on the reaming member 9 projected on the first movable plate 7 is smaller than the inner diameter of the condenser tube 6, and the maximum diameter is larger than the outer diameter of the condenser tube 6, so that the reaming member 9 expands one end of the adjacent condenser tube 6 during the movement, so that the diameter of the end of the condenser tube 6 after expansion is larger than its original diameter.

[0025] like Figure 6 As shown, the minimum distance between adjacent expansion members 9 is smaller than the length of the condenser tube 6 , ensuring that the two ends of the condenser tube 6 can be respectively squeezed and expanded by the adjacent expansion members 9 .

[0026] like Figure 4-Figure 6As shown, the first movable plate 7 and the second movable plate 8 are both fixed with a number of fixing parts 10, and the number of the fixing parts 10 is the same as the number of the reaming parts 9. The reaming parts 9 slide in the adjacent fixing parts 10. The reaming parts 9 are provided with rubber pads for increasing the sealing between them and the adjacent fixing parts 10. The fixing parts 10 are provided with internal threads. The internal threads of the fixing parts 10 are connected to the pressure caps 11. The pressure caps 11 are provided with through holes connected to the adjacent reaming parts 9. The pressure caps 11 are used to squeeze the adjacent reaming parts 9 and maintain the stability of the positions of the adjacent reaming parts 9.

[0027] like Figure 5 and Figure 6 As shown, it also includes a plurality of first movable rings 12. The number of the first movable rings 12 is the same as the number of the reaming members 9. The reaming members 9 are slidingly connected with circumferentially distributed connecting rods. The first movable rings 12 are fixed to the connecting rods of the adjacent reaming members 9. The first movable rings 12 are slidingly connected with the adjacent condenser tubes 6. A rubber ring is provided on the side of the first movable ring 12 away from the adjacent reaming member 9, which is used to increase the sealing between the condenser tube 6 and the first movable ring 12, and at the same time increase the sealing between the first movable ring 12 and the adjacent fixed plate 4 or the connecting shell 5.

[0028] like Figure 6 As shown, the inner diameter of the first movable ring 12 is equal to the outer diameter of the condenser tube 6, so that the first movable ring 12 can squeeze the expansion portion of the adjacent condenser tube 6 during the movement, causing the expansion portion of the condenser tube 6 to shrink.

[0029] The workflow of the above solution is as follows: When it is necessary to use this device to condense the product (gaseous product) in the methane disulfonic acid extraction process, the staff connects the external condensate pipe to the upper port of the diversion shell 2, and connects the drain pipe to the lower port of the diversion shell 2, and uses the existing pumping device to transport the condensate into the cavity at the upper part of the diversion shell 2, and then flows to the right along the upper left condensate pipe 6 to the storage cavity at the upper part of the connecting shell 5, while the condensate flowing into the storage cavity at the upper part of the connecting shell 5 continues to flow to the right along the upper right condensate pipe 6 to the fixed shell 3. The condensate flowing into the fixed shell 3 flows through the lower right condensate pipe 6, the storage cavity at the bottom of the connecting shell 5 and the lower left condensate pipe 6 in turn to flow into the cavity at the lower part of the diversion shell 2, and is discharged outward along the lower port of the diversion shell 2. During this process, the staff can use the pipeline to transport the condensate flowing out of the lower port of the diversion shell 2 to other locations that need to be heated, thereby recycling the waste heat of the condensate.

[0030] While conveying condensed water into the diversion shell 2, the staff connects the air inlet on the upper part of the condensing shell 1 with the gas conveying pipeline, guides the product to be condensed (hereinafter described as hot gas as an example) into the condensing shell 1, and flows to the right along the condensing shell 1. During the flow of hot gas, heat exchange occurs with the condensing tube 6, causing the hot gas to condense into liquid, which flows out from the drain port at the bottom of the condensing shell 1 and is collected by the staff. After the device has been used for a specified time (the time can be selected by the staff), the staff stops conveying hot air into the condensing shell 1, releases the condensed liquid and residual hot air in the condensing shell 1, and stops conveying condensed water into the diversion shell 2 at the same time. After releasing the residual condensed water in the storage cavity of the diversion shell 2, the fixed shell 3, the connecting shell 5 and all the condensing tubes 6, the device is cleaned and maintained for subsequent use.

[0031] During normal use of an existing tubular condenser, if a heat exchange tube inside the condenser is damaged, the entire tube needs to be removed and replaced, resulting in the originally intact tube section being forced to be scrapped, causing unnecessary economic losses.

[0032] To solve the above problems, the present device adopts a segmented condenser tube 6 design. When one of the condenser tubes 6 needs to be replaced (the frontmost one among the multiple condenser tubes 6 in the upper left part is taken as an example), the staff continues to transport hot air into the condensing shell 1 according to the above operation, and after the residual hot air, condensed liquid and residual condensed water are released according to the above operation, the condensing shell 1 is opened, and the staff rotates the two pressure covers 11 corresponding to the condenser tube 6, separates the two pressure covers 11 from the adjacent fixing parts 10, and then moves the corresponding two reaming parts 9 to make the two reaming parts 9 move away from each other, and simultaneously separate the two reaming parts 9 from the left and right ends of the condenser tube 6.

[0033] During the movement of the reamer 9, the first movable ring 12 is intercepted by the expansion part of the adjacent condenser tube 6 and cannot move, causing the reamer 9 and the connecting rod thereon to move relative to each other until the distance between the reamer 9 and the adjacent first movable ring 12 reaches the maximum (at this time the reamer 9 and the adjacent condenser tube 6 are completely separated), and the connecting rod on the reamer 9 moves to the extreme position relative to the reamer 9, so that the reamer 9 and the adjacent first movable ring 12 can no longer move relative to each other, and then the reamer 9 drives the adjacent first movable ring 12 to move synchronously through the adjacent connecting rod during the movement, and the first movable ring 12 squeezes the expansion part of the adjacent condenser tube 6 during the movement, causing the expansion part of the condenser tube 6 to shrink in the direction close to its central axis, until the first movable ring 12 is completely separated from the adjacent condenser tube 6, and the staff can take out the condenser tube 6.

[0034] After taking out the condenser tube 6 that needs to be replaced, the staff puts the new condenser tube 6 to the corresponding position, and then puts the rightmost side of the inclined ring surface of the left reaming piece 9 into the corresponding fixing piece 10. In this process, the first movable ring 12 on the left is sleeved on the left end of the condenser tube 6, and then the left pressure cover 11 is fixed to the corresponding fixing piece 10. In the process of installing the left pressure cover 11, the pressure cover 11 squeezes the reaming piece 9 to move the reaming piece 9 to the right. The installation process of the right pressure cover 11 and the movement process of the right reaming piece 9 can refer to the above, and the two reaming pieces 9 squeeze the left and right ends of the new condenser tube 6 respectively through the inclined ring surfaces thereon during the movement, so that The left and right ends of the new condenser 6 are squeezed and expanded (forming an expansion portion). At the same time, during the expansion process of the two ends of the new condenser 6, the expansion member 9 on the left squeezes the first movable ring 12 on the left through the connecting rod thereon. The first movable ring 12 on the left drives the rubber ring on it to move synchronously to the right, so that the rubber ring on the first movable ring 12 on the left is deformed by the joint extrusion force of the adjacent fixed plate 4 and the expansion member 9, thereby increasing the sealing between the first movable ring 12 on the left and the adjacent fixed plate 4, and at the same time increasing the sealing between the first movable ring 12 on the left and the adjacent condenser 6 (the rest of the movement process of the first movable ring 12 can refer to the above and will not be described in detail).

[0035] When comprehensive corrosion or serious blockage occurs, all condenser tubes 6 need to be replaced. The staff will remove the four first movable plates 7 from the adjacent fixed plates 4 respectively, and the first movable plates 7 will drive all the reaming parts 9 thereon to move, so that the part of the reaming parts 9 is separated from one end of the adjacent condenser tube 6 respectively. In the process of disassembling the four first movable plates 7, the staff will move the four second movable plates 8 at the same time, so that the two second movable plates 8 located in the same storage cavity on the connecting shell 5 are close to each other, and the second movable plates 8 will drive all the reaming parts 9 thereon to move, so that the part of the reaming parts 9 is separated from the other end of the adjacent condenser tube 6 respectively. Then the staff can remove all the condenser tubes 6 in turn, and install the new condenser tubes 6 in the designated positions in turn.

[0036] After all the new condenser tubes 6 are placed, the staff first installs the first movable plate 7 on the upper left side with the adjacent fixed plate 4, so that all the reaming parts 9 on the first movable plate 7 on the upper left side are in contact with the left end of the adjacent condenser tube 6 respectively, and then moves the second movable plate 8 on the upper left side to the right. During the movement, the second movable plate 8 drives all the reaming parts 9 on it to move synchronously, and the reaming parts 9 on the second movable plate 8 squeeze the right end of the adjacent condenser tube 6 during the movement, so that the condenser tube 6 moves to the left. In this process, the left end of the condenser tube 6 is squeezed by the adjacent reaming parts 9, so that the two ends of the condenser tube 6 are expanded respectively under the action of the squeezing of the adjacent reaming parts 9, while increasing the sealing between the condenser tube 6 and the adjacent fixed plate 4 and the connecting shell 5 (the maximum diameter of the left and right ends of the condenser tube 6 after expansion is significantly larger than its original diameter, so that the left and right ends of the condenser tube 6 can be stuck between the connecting shell 5 and the adjacent fixed plate 4, thereby completing the fixation of the condenser tube 6), maintaining the stability of the position of the condenser tube 6 during normal use.

[0037] Example 2

[0038] like Figure 1 、 Figure 2 and Figure 7-10 As shown, there are also two exhaust pipes 13, both of which are fixed to the connecting shell 5, one of the exhaust pipes 13 is connected to the upper storage cavity of the connecting shell 5, and the other exhaust pipe 13 is connected to the lower storage cavity of the connecting shell 5, and is used to discharge the gas contained in the condensed water in the connecting shell 5. The position where the connecting shell 5 is connected to the two exhaust pipes 13 is provided with a conical surface, which gathers the gas contained in the condensed water in the connecting shell 5 through the conical surface and guides the gas into the corresponding exhaust pipe 13.

[0039] like Figure 7-10As shown, a suction component is also included, which is used to accelerate the precipitation speed of the gas in the condensed water of the connecting shell 5. The suction component is arranged on the condensing shell 1, and the suction component includes two positioning rings 14, two second movable rings 15, two sealing covers 16, an electric push rod 17 and two movable rods 18. The two positioning rings 14 are respectively fixed in the adjacent exhaust pipes 13, and the two second movable rings 15 are respectively slidably connected in the adjacent exhaust pipes 13. The positioning rings 14 are used to block the adjacent second movable rings 15. The projection of the second movable rings 15 on the vertical plane is "convex". The two sealing covers 16 are respectively rotatably connected to the adjacent second movable rings 15. In the normal state, the sealing covers 16 are not parallel to the horizontal plane. The position of the sealing cover 16 in the figure is shown as parallel to the horizontal plane, not its initial position. The sealing cover 16 is used to block the adjacent second movable rings 15. When the sealing cover 16 rotates to a horizontal state, the sealing cover 16 fits with the adjacent second movable ring 15 and blocks the second movable ring 15, so that the sealing cover 16 and the adjacent second movable ring 15 form a piston-like structure together. There is friction between the second movable ring 15 and the adjacent exhaust pipe 13, ensuring that when the moving rod 18 drives the adjacent second movable ring 15 to move downward through the adjacent sealing cover 16, the sealing cover 16 first rotates to a tilted state, and then the moving rod 18 drives the adjacent second movable ring 15 to move downward at the same time through the adjacent sealing cover 16. The electric push rod 17 is fixed to the condensation shell 1, and the telescopic end of the electric push rod 17 is fixed with a connecting plate. The two moving rods 18 are both rotatably connected to the connecting plate. The moving rod 18 slides and rotates with the adjacent sealing cover 16, and the telescopic end of the electric push rod 17 drives the two sealing covers 16 to move synchronously through the transmission of the connecting plate and the two moving rods 18.

[0040] The specific workflow of the above solution is as follows: In the process of transporting condensed water into the diversion shell 2, the staff controls the flow rate of the condensed water by controlling the power of the pumping device, so that the condensed water in the connecting shell 5 is always at a relatively stable volume, that is, the condensed water liquid level in the two storage chambers of the connecting shell 5 is maintained stable.

[0041] During the flow of condensed water, the gas in the condensed water gradually floats upward, and after the condensed water flows into the storage cavity of the connecting shell 5, it is guided by the conical surface on the connecting shell 5 to gather in the exhaust pipe 13 and discharged outward along the exhaust pipe 13, reducing the gas content in the condensed water, so that the cooling water can flow stably in the condenser pipe 6, while improving the heat transfer efficiency between the condensed water and the hot air, thereby improving the overall condensation efficiency.

[0042] During the process of condensing the hot air, the staff starts the electric push rod 17 to make the telescopic end of the electric push rod 17 move back and forth up and down. The telescopic end of the electric push rod 17 drives the two moving rods 18 to move upward synchronously through the connecting plate during the upward movement. The two moving rods 18 respectively drive the adjacent sealing covers 16 to move synchronously during the upward movement, so that the sealing cover 16 rotates along the connection between it and the adjacent second moving ring 15 until the sealing cover 16 rotates to a horizontal state. The sealing cover 16 blocks the adjacent second moving ring 15, and then the sealing cover 16 drives the adjacent second moving ring 15 to move upward synchronously, thereby extracting the gas in the two storage cavities of the connecting shell 5, thereby increasing the precipitation rate of the gas in the condensed water.

[0043] After the telescopic end of the electric push rod 17 moves upward to the limit position, the staff controls the telescopic end of the electric push rod 17 to drive the two moving rods 18 to move downward through the connecting plate, so that the two moving rods 18 squeeze the adjacent sealing covers 16 respectively during the movement, so that the two sealing covers 16 rotate along the connection between them and the adjacent second moving rings 15 (the sealing covers 16 rotate from a horizontal state to an inclined state), and the adjacent second moving rings 15 are released, so that the precipitated gas can flow upward along the second moving rings 15. Until the sealing cover 16 rotates to the limit position, the moving rod 18 drives the adjacent second moving ring 15 to move downward through the adjacent sealing cover 16, until the second moving ring 15 contacts the adjacent positioning ring 14 again, the staff controls the telescopic end of the electric push rod 17 to move upward again, and repeats the above steps until the device is used for the specified time, and the staff shuts down the electric push rod 17 for subsequent use.

[0044] Example 3

[0045] like Figures 8-10 As shown, the suction assembly also includes two limit rings 19 and two floats 20. The two limit rings 19 are fixed to the adjacent exhaust pipes 13 through brackets, and the two floats 20 are respectively located on the adjacent limit rings 19. The positioning ring 14 is located between the adjacent limit ring 19 and the adjacent second movable ring 15. When condensed water enters the exhaust pipe 13, the float 20 floats up due to the buoyancy of the condensed water. The float 20 is used to seal the adjacent positioning ring 14.

[0046] like Figure 10 As shown, the outer diameter of the limit ring 19 is smaller than the inner diameter of the exhaust pipe 13, and the diameter of the float 20 is smaller than the inner diameter of the exhaust pipe 13, but larger than the inner diameter of the positioning ring 14 and the inner diameter of the limit ring 19, and the float 20 is made of elastic deformable material to ensure that when the float 20 moves upward to contact the lower side of the adjacent positioning ring 14, the float 20 can block the adjacent positioning ring 14 to prevent condensed water from leaking upward through the exhaust pipe 13.

[0047] The specific workflow of the above solution is as follows: During the process of the gases in the two storage chambers of the connecting shell 5 being discharged outward along the adjacent exhaust pipes 13, when pressure fluctuations occur in the flow of condensed water, the liquid levels of the condensed water in the two storage chambers of the connecting shell 5 may rise briefly. At this time, the condensed water in the two storage chambers is guided by the two conical surfaces on the connecting shell 5 and flows into the two exhaust pipes 13 respectively, and pushes the floats 20 in the two exhaust pipes 13 to move the two floats 20 upward until the floats 20 move upward to contact the lower side surfaces of the adjacent positioning rings 14. The floats 20 then block the adjacent positioning rings 14, thereby blocking the exhaust pipes 13, preventing the condensed water from flowing upward along the exhaust pipes 13, maintaining the stability of the condensed water level in the connecting shell 5, and ensuring that the condensed water flows along the condensation pipe 6, thereby ensuring the condensation effect on the hot air.

[0048] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and application concept of the present invention within the technical scope described in the present invention, and they should be covered by the scope of protection of the present invention.
