Description

Technical Field

[0001] This utility model relates to the field of chemical machinery and equipment technology, specifically a distillation column with an adjustable stripping section. Background Technology

[0002] The dilute hydrochloric acid containing alcohols and ethers in the acid tank is heated by the condensing acid transfer pump through a double-effect heat exchanger and then fed into the lower part of the methanol recovery tower. Most distillation towers repeatedly heat, condense, and heat the methanol in the dilute hydrochloric acid, which consumes a lot of energy and is not conducive to energy saving and consumption reduction. Moreover, because the feed inlet of the distillation tower is at the bottom, the methanol distillation effect in the hydrochloric acid is poor. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a distillation column with an adjustable stripping section, which solves the problem of poor methanol distillation efficiency in hydrochloric acid.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a distillation column with an adjustable stripping section height, comprising a distillation column assembly, an outer cylinder disposed inside the distillation column assembly, a discharge port extending through the outer wall above the outer cylinder, a discharge port extending through the inner wall below the outer cylinder, and a support leg fixedly connected to the lower part of the outer wall of the outer cylinder. The column also includes an adjustment assembly, rotatably connected to the distillation column assembly and meshing with a stripping section assembly, with an anti-backflow assembly fixedly connected above the stripping section assembly. The adjustment assembly includes a rotating rod, a gear fixedly connected to the outer wall of the rotating rod, rotatably connected to the outer cylinder, a handle fixedly connected to one end of the rotating rod located on the outer wall of the outer cylinder, and a rack meshing with the outer wall of the gear. The rack is slidably connected to a guide rod on its outer wall away from the gear, and a pin is slidably connected to the handle on its inner wall away from the outer cylinder. A thrust spring is sleeved on the outside of the pin. The end of the pin away from the handle is inserted into a limiting hole on the outer wall of the outer cylinder. A fixing plate with a limiting rotating rod is fixedly connected to the outer wall of the outer cylinder. By rotating the handle, the rotating rod and gear are driven to rotate, which in turn drives the rack to move, thus realizing the driving of the stripping section component. The operation is simple and convenient. The guide rod ensures the stability and accuracy of the rack movement. The cooperation between the pin and the limiting hole can fix its position after the height of the stripping section is adjusted, preventing the height of the stripping section from changing due to external forces during operation, thus ensuring the stability of the distillation process. The fixing plate limits the rotating rod, avoiding axial displacement of the rotating rod from affecting the transmission effect.

[0005] Preferably, the outer wall below the guide rod is fixedly connected to the inner wall below the outer cylinder. A protective sleeve is fitted over the thrust spring. One end of the thrust spring is fixedly connected to the handle, and the other end is fixedly connected to the pin. The fixed installation of the guide rod ensures the stability of its guiding effect on the rack and further improves the accuracy of the rack's movement. The protective sleeve extends the service life of the thrust spring and reduces the impact of the external environment. The fixed connection at both ends of the thrust spring ensures that it can continuously provide a stable thrust to the pin, ensuring reliable insertion of the pin into the limiting hole.

[0006] Preferably, the anti-backflow assembly includes a second hose, with a fixed rod fixedly connected inside the second hose. A sleeve is fixedly connected to the outer wall of the fixed rod, and a tension spring is fixedly connected to the inner wall of the sleeve. A movable rod is fixedly connected to the inner wall of the tension spring away from the sleeve. A movable plate is fixedly connected to the outer wall of the movable rod away from the tension spring. A blocking ring is fitted onto the outer wall of the movable plate near the movable rod. The flexibility of the second hose allows it to adapt to changes in the height of the distillation section assembly, ensuring that the anti-backflow assembly always functions normally. When the material shows a backflow tendency, the movable plate is tightly fitted with the blocking ring under the action of the tension spring, thereby preventing the material from flowing back and effectively ensuring the normal operation of the distillation process, improving the distillation effect and quality.

[0007] Preferably, the movable rod is slidably connected to the sleeve, the movable rod is located inside the sleeve, the outer wall of the blocking ring is fixedly connected to the inner wall of the second hose, and the outer wall of the second hose penetrates the inner wall of the feed inlet. The slidable connection between the movable rod and the sleeve ensures that the movable plate can move flexibly, thereby better playing the role of preventing backflow. The fixed installation of the blocking ring enables it to stably block the movable plate, improving the reliability of preventing backflow. The cooperation between the second hose and the feed inlet facilitates the smooth entry of materials into the distillation column, ensuring the continuous operation of the distillation process.

[0008] Preferably, the stripping section assembly includes an inner cylinder, the inner cylinder having a filling material fixedly connected inside, a slider fixedly connected to the lower part of the outer wall of the inner cylinder, a first flexible tube connected through the lower part of the outer wall of the inner cylinder, a guide ring fixedly connected to the upper part of the outer wall of the inner cylinder, and a connecting rod fixedly connected to the upper part of the outer wall of the guide ring. The filling material inside the inner cylinder increases the contact area of ​​the material, improving the stripping efficiency and effect. The slider makes the inner cylinder move more smoothly and steadily, reducing friction and resistance. The first flexible tube facilitates material circulation, ensuring the continuity of the stripping process. The guide ring provides good guidance for the material, allowing it to be evenly distributed, further improving the stripping effect. The connecting rod firmly connects the inner cylinder to the anti-backflow assembly, ensuring their coordinated operation.

[0009] Preferably, the outer wall above the connecting rod is fixedly connected to the anti-backflow assembly, the outer wall of the slider is slidably connected to the inner wall of the outer cylinder, the outer wall of the first hose is fixedly connected to the inner wall of the discharge port, one side of the lower outer wall of the inner cylinder is fixedly connected to the outer wall above the rack, the inner cylinder is located inside the outer cylinder, and the inner and outer cylinders are slidably connected. The fixed connection of the connecting rod ensures the coordinated movement of the stripping section assembly and the anti-backflow assembly, improving the overall integrity and stability of the entire device. The slidable connection between the slider and the inner wall of the outer cylinder makes the movement of the inner cylinder smoother and reduces wear during movement. The connection between the first hose and the discharge port ensures normal material circulation, which is beneficial to improving distillation efficiency. The connection between the inner cylinder and the rack allows the height of the inner cylinder, i.e., the height of the stripping section, to be easily adjusted by the adjustment assembly, increasing the flexibility and applicability of the distillation column. The slidable connection between the inner cylinder and the outer cylinder provides the possibility for adjusting the height of the stripping section, meeting the needs of different distillation processes.

[0010] This invention provides a distillation column with an adjustable stripping section. It offers the following advantages: (i) The distillation column with adjustable stripping section height can be adjusted by adjusting the stripping section height to meet the different requirements of different materials for stripping section height during the distillation process, enhance the adaptability of the equipment to various production scenarios, eliminate the need to replace equipment due to material changes, and reduce production costs.

[0011] (ii) This distillation column with adjustable stripping section increases the material contact area through the packing material inside the inner cylinder, which helps the material to fully carry out the stripping reaction; the guide ring can make the material evenly distributed inside the inner cylinder, improving the stripping efficiency; the anti-reflux component can effectively prevent the material from flowing back, ensuring the stability of the distillation process, reducing material waste and poor distillation effect caused by reflux, thereby improving the quality of the final fraction.

A handle 23 is fixedly connected to one end of the rotating rod 21 located on the outer wall of the outer cylinder 11. A rack 27 is meshed with the outer wall of the gear 22. A guide rod 26 is slidably connected to the outer wall of the rack 27 away from the gear 22. A pin 25 is slidably connected to the inner wall of the handle 23 away from the outer cylinder 11. A thrust spring 24 is sleeved on the outside of the pin 25. The end of the pin 25 away from the handle 23 is inserted into a limiting hole opened on the outer wall of the outer cylinder 11. A fixing plate with a limiting rotating rod 21 is fixedly connected to the outer wall of the outer cylinder 11.

[0016] The outer wall below the guide rod 26 is fixedly connected to the inner wall below the outer cylinder 11. The thrust spring 24 is covered with a protective sleeve. One end of the thrust spring 24 is fixedly connected to the handle 23, and the other end of the thrust spring 24 is fixedly connected to the pin 25.

[0017] The anti-backflow assembly 4 includes a second hose 41, a fixed rod 47 is fixedly connected inside the second hose 41, a sleeve 45 is fixedly connected to the outer wall of the fixed rod 47, a tension spring 46 is fixedly connected to the inner wall of the sleeve 45, a movable rod 44 is fixedly connected to the inner wall of the tension spring 46 away from the sleeve 45, a movable plate 43 is fixedly connected to the outer wall of the movable rod 44 away from the tension spring 46, and a blocking ring 42 is attached to the outer wall of the movable plate 43 near the movable rod 44.

[0018] The movable rod 44 is slidably connected to the sleeve 45, the movable rod 44 is located inside the sleeve 45, the outer wall of the blocking ring 42 is fixedly connected to the inner wall of the second hose 41, and the outer wall of the second hose 41 penetrates the inner wall of the feed port 14.

[0019] The stripping section assembly 3 includes an inner cylinder 31, with a packing material 32 fixedly connected inside the inner cylinder 31. A slider 36 is fixedly connected to the lower part of the outer wall of the inner cylinder 31. A first flexible tube 37 is connected through the lower part of the outer wall of the inner cylinder 31. A flow guide ring 33 is fixedly connected to the upper part of the outer wall of the inner cylinder 31. A connecting rod 34 is fixedly connected to the upper part of the outer wall of the flow guide ring 33.

[0020] The outer wall above the connecting rod 34 is fixedly connected to the anti-backflow component 4, the outer wall of the slider 36 is slidably connected to the inner wall of the outer cylinder 11, the outer wall of the first hose 37 is fixedly connected to the inner wall of the discharge port 13, one side of the lower outer wall of the inner cylinder 31 is fixedly connected to the outer wall above the rack 27, the inner cylinder 31 is located inside the outer cylinder 11, and the inner cylinder 31 and the outer cylinder 11 are slidably connected.

[0021] In use, the device is placed in the workshop, and the inlet 14 and outlet 15 are connected to the external equipment. The material to be distilled enters the second hose 41 of the anti-backflow component 4 through the inlet 14, and then enters the inner cylinder 31 of the stripping section component 3. The filling material 32 inside the inner cylinder 31 increases the contact area of ​​the material, which helps the material to carry out the stripping reaction better. Some of the material generated during the stripping process will be discharged through the first hose 37 connected to the lower outer wall of the inner cylinder 31 and discharged through the outlet 13. The final fraction will be discharged through the outlet 15 on the upper outer wall of the outer cylinder 11.

[0022] When the height of the stripping section needs to be adjusted, this is achieved using the adjusting assembly 2. During operation, pull the pin 25 to overcome the force of the thrust spring 24 and pull it out of the limiting hole on the outer wall of the outer cylinder 11. At this time, the handle 23 can rotate freely. Rotating the handle 23 drives the rotating rod 21 to rotate, and the gear 22 on the outer wall of the rotating rod 21 rotates accordingly. Since the gear 22 is meshed with the rack 27, the rotation of the gear 22 will drive the rack 27 to move linearly along the guide rod 26. The rack 27 is fixedly connected to one side of the lower outer wall of the inner cylinder 31, therefore the gear... The movement of bar 27 causes the inner cylinder 31 to slide inside the outer cylinder 11. The slider 36 below the outer wall of the inner cylinder 31 slides on the inner wall of the outer cylinder 11, assisting the inner cylinder 31 to maintain stable movement, thereby realizing the adjustment of the height of the stripping section. After adjusting to the appropriate height, the pin 25 is released. Under the action of the thrust spring 24, the pin 25 is re-inserted into the limiting hole on the outer wall of the outer cylinder 11, fixing the position of the handle 23, thereby fixing the height of the stripping section. At the same time, the fixing plate on the outer wall of the outer cylinder 11 plays a limiting role on the rotating rod 21, ensuring the stable operation of the rotating rod 21.

[0023] The anti-backflow component 4 effectively prevents material backflow during operation. When material enters normally, the pressure of the material pushes the movable plate 43, which in turn drives the movable rod 44 to slide within the sleeve 45. The tension spring 46 is stretched, and the movable plate 43 separates from the blocking ring 42, allowing the material to pass smoothly. When a backflow tendency occurs, the pressure of the material on the movable plate 43 decreases, the tension spring 46 returns to its original state, and the movable rod 44 and the movable plate 43 are pulled back to their original positions. The movable plate 43 then fits against the blocking ring 42, thereby preventing material backflow. In addition, the guide ring 33 on the outer wall above the inner cylinder 31 can guide the material, allowing it to enter the relevant components more evenly. The connecting rod 34 fixes the inner cylinder 31 and the anti-backflow component 4 together, ensuring coordinated movement. The flexibility of the second hose 41 can also adapt to positional changes during the height adjustment of the distillation section.
