Description

Technical Field

[0001] The present invention relates to the technical field of distillation towers, and in particular to a baffle-type distillation tower. Background Art

[0002] Distillation towers are widely used as core equipment for separating and purifying mixtures. Currently, these towers typically utilize a monolithic design, which ensures tightness and stability during manufacturing and installation. However, when internal faults occur, such as damaged trays, clogged packing, or loose internal components, repairs present numerous challenges.

[0003] For large distillation towers, maintenance personnel can enter the tower to work, but due to the small internal space and complex environment of the distillation tower, not only is the operation extremely inconvenient, but they may also face safety risks such as harmful gas residue, hypoxia, and falling from heights, posing a serious threat to the personal safety of maintenance personnel.

[0004] However, for small and medium-sized distillation towers, maintenance personnel cannot enter the tower to perform operations. They can only use related tools to repair the internal parts of the distillation tower. This is not only difficult to repair, but also inefficient and has a long maintenance cycle, which in turn affects production progress and increases enterprise operating costs. Therefore, the above problems need to be solved urgently. Summary of the Invention

The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0077] In this embodiment, the tower body 100 includes heads at both ends and a tower body in the middle; the tower body is formed by connecting multiple tower sections using flanges at both ends; the tower sections are divided into a first tower section 200 and a second tower section 300 according to different internal structures; at the same time, the first tower section 200 also includes a special tower section with a feed port 110 on one side; the second tower section 300 also includes a special tower section with a connecting port for connecting to the heat exchanger 120 and the reboiler 130.

[0078] In this embodiment, the interior of the first tower section 200 is provided with a partition 210 extending in the axial direction, which is used to separate the interior of the first tower section 200 into an independent pre-separation area and a main separation area; when the tower body is spliced, multiple first tower sections 200 are continuously installed in the middle to form a partition-type distillation tower; on the contrary, if the entire tower body is spliced ​​by the second tower sections 300, a conventional distillation tower will be formed.

[0079] In this embodiment, the pre-separation zone and the main separation zone have the same cross-sectional structure and size, so a first tower plate 220 with the same structure is installed; the first tower plate 220 is respectively provided with a first inlet weir 221 and a first outlet weir 222 at both ends along the straight side direction; at the same time, the first tower plate 220 is located on the side of the first outlet weir 222 away from the first inlet weir 221 and is also provided with a corresponding through hole and a first downcomer 223 extending downward.

[0080] In this embodiment, a circular second tower plate 310 is provided inside the second tower section 300; a second inlet weir 311 and a second outlet weir 312 are respectively provided at both ends of the second tower plate 310 in the radial direction; at the same time, the second tower plate 310 is located on the side of the second outlet weir 312 away from the second inlet weir 311 and is also provided with a corresponding through hole and a second downcomer 313 extending downward.

[0081] In this embodiment, the driving mechanism is located outside the tower section, and includes a screw rod 400 extending along the axis of the tower section and a slider 410 threadedly connected to the screw rod 400; the two ends of the screw rod 400 are rotatably mounted on the outer wall of the tower section through bearings; the slider 410 is connected to the internal docking plate 420 through a strip hole on the side wall of the tower section; the width of the strip hole matches the width of the slider 410, thereby effectively limiting the slider 410 from rotating with the screw rod 400; at the same time, the length of the strip hole is much larger than the length of the slider 410, so that the slider 410 can slide arbitrarily within a range.

[0082] In this embodiment, the docking plate 420 is integrally formed with the first tower plate 220 , and is located between the first inlet weir 221 and the first outlet weir 222 and at one end away from the partition plate 210 .

[0083] In this embodiment, the docking plate 420 is integrally formed with the second tower plate 310 and is located at the edge between the second inlet weir 311 and the second outlet weir 312 .

[0084] In this embodiment, the docking plate 420 is respectively located on the upper and lower sides of the first tower plate 220 / the second tower plate 310, and the outer edge is in contact with the inner wall of the first tower section 200 / the second tower section 300, and its length is relatively larger than the length of the strip hole, so that it can be connected to the slider 410 through the strip hole and the strip hole can be sealed.

[0085] In a preferred embodiment, the two ends of the screw rod 400 are respectively provided with a forward thread and a reverse thread with opposite rotation directions, which are used to drive the corresponding slider 410 to move in the opposite direction; the forward thread and the reverse thread are respectively multi-section structures with different pitches, which are used to drive the sliders 410 to form a stroke difference; the pitch of the end where the multi-section forward thread and the reverse thread are close to each other is relatively small.

[0086] In this embodiment, forward threads and reverse threads are respectively provided at both ends of the screw rod 400. The forward threads and reverse threads respectively include multiple sections with different pitches, which are used to drive different sliders 410 to slide in different directions and distances, so that the multiple sliders 410 always maintain equal distances.

[0087] In this embodiment, five corresponding tower plates are usually installed in the tower section; among them, the tower plate in the middle is fixedly installed on the tower section or the corresponding slider and the screw rod 400 are installed in the middle of the screw rod 400 through bearings, and the tower plates on both sides slide to the corresponding sides respectively during the rotation of the screw rod 400.

[0088] In this embodiment, the ratio of the thread pitches of the two sections on the same side of the screw rod 400 is 1:3, and the thread pitch near the middle is relatively small.

[0089] In a preferred embodiment, a protective cover 430 is further provided on the tower section corresponding to the screw rod 400; the protective cover 430 is a closed structure, and a stepper motor 440 for driving the screw rod 400 is provided on the outside; a first worm 441 is installed at the output end of the stepper motor 440; the first worm 441 extends from one end of the stepper motor 440 to the inside of the protective cover 430, and the axial direction is perpendicular to the screw rod 400; the screw rod 400 and the first worm 441 are driven and connected by a matching first worm gear 401.

[0090] In this embodiment, the protective cover 430 includes a rectangular frame welded to the outer wall of the tower section and an end cover installed on the frame; the end cover and the frame are fastened together by bolts, thereby ensuring that the protective cover 430 can seal the strip hole and that the interior can be operated by removing the end cover.

[0091] In this embodiment, the screw rod 400 is a stepped shaft, the diameter of which is relatively large in the middle and relatively small at both ends, thereby effectively ensuring that the corresponding sliders 410 can be connected with the corresponding external threads.

[0092] In this embodiment, the screw rod 400 is driven by a stepper motor 440; the stepper motor 440 is fixedly mounted on the outside of the protective cover 430 and is driven and connected to the screw rod 400 through a first worm 441; a corresponding first worm wheel 401 is provided on the screw rod 400 corresponding to the first worm 441; the stepper motor 440 and the screw rod 400 are connected by a worm gear mechanism, which not only satisfies the transmission connection, but also realizes the self-locking of the screw rod 400, thereby preventing the spacing of the tower plates from changing.

[0093] In a preferred embodiment, the first tower section 200 is slidably connected to the partition 210, and a matching slide groove 201 is provided on the inner wall corresponding to the partition 210; the two ends of the partition 210 in the vertical direction are respectively provided with a docking male head 211 and a docking female head 212 for forming a sealed connection.

[0094] In this embodiment, the partition 210 is slidably installed on the first tower section 200, and at the same time, embedded sliding grooves 201 are respectively provided on the inner wall of the first tower section 200 corresponding to both sides of the partition 210; by adopting the embedded sliding grooves 201, not only the sliding direction of the partition 210 can be limited, but also the flatness of the inner wall of the first tower section 200 can be ensured, thereby reducing the impact on distillation.

[0095] In this embodiment, the docking female head 212 has a U-shaped groove structure, and the groove width is relatively smaller than the thickness of the partition 210, thereby ensuring the surface flatness of the partition after splicing; the docking male head 211 has a raised structure and matches the U-shaped groove. By plugging it into the docking female head 212, a complete partition can be formed between the two partitions 210.

[0096] In this embodiment, the length of the docking male head 211 matches the inner diameter of the first tower section 200 , and sealing portions with the same height as the first tower section 200 but the same thickness as the partition 210 are provided at both ends to form a sealed connection with the slide groove 201 .

[0097] In a preferred embodiment, a driving assembly is further provided inside the partition 210 for driving the partition 210 and the slide 201 to slide against each other; the driving assembly includes a second worm 213 extending in a vertical direction and a rotating shaft 214 perpendicular to the second worm 213; the middle of the rotating shaft 214 is driven and connected to the second worm 213 through a second worm gear 215, and both ends extend to the outside of the partition 210 and are respectively equipped with corresponding gears 216; a matching rack 202 is provided on the inner wall of the slide 201 corresponding to the gear 216, and is fixedly connected to the rack 202.

[0098] In this embodiment, the driving assembly is arranged inside the partition 210, including a second worm 213 and a rotating shaft 214 that are perpendicular to each other; the second worm 213 extends in a vertical direction so that it can be operated through the top of the partition 210; the rotating shaft 214 is driven and connected to the second worm 213 through the second worm wheel 215.

[0099] In this embodiment, both ends of the rotating shaft 214 extend to the outside of the partition 210 respectively, and are installed with gears 216; the gear 216 is located inside the slide groove 201, and is meshed with the rack 202 in the slide groove 201. By driving the second worm 213 to rotate, the partition 210 can be effectively driven to rise and fall relative to the slide groove 201; at the same time, the second worm 213 and the second worm gear 215 can also form a self-locking function. When the two adjacent partitions 210 are docked and pressed and sealed through the corresponding docking male head 211 and the docking female head 212, the self-locking function can also be used to prevent the docking male head 211 and the docking female head 212 from accidentally loosening, thereby affecting the sealing effect.

[0100] In this embodiment, the cross-section of the slide groove 201 is a horizontal convex shape, and the width of the side closer to the partition 210 is relatively small, which is used to form a sliding seal between the partition 210; the width of the side away from the partition 210 is relatively large, which is used to install the rack 202 and connect it with the gear 216.

[0101] In a preferred embodiment, the top of the partition 210 is provided with a connecting hole coaxial with the second worm 213 for driving the second worm 213; the top of the second worm 213 is provided with a hexagonal countersunk hole for docking with an external drive wrench.

[0102] In this embodiment, a docking female head 212 is usually provided on the top of the partition 210; a connecting hole coaxial with the second worm 213 is provided in the U-shaped groove of the docking female head 212, so that the second worm 213 can be directly rotated through the connecting hole.

[0103] In this embodiment, a countersunk hole in the form of a regular hexagon is provided at one end of the second worm 213 close to the communicating hole, so that the countersunk hole can be connected to a corresponding hexagonal wrench.

[0104] In a preferred embodiment, the outside of the tower section is further provided with a support ear 500; the number of the support ears 500 includes multiple, and they are arranged in an array; the multiple support ears 500 are connected by a connecting rod 510 to form a support frame; the adjacent support frames are connected by a lifting support mechanism to drive the relative lifting between the two tower sections.

[0105] In this embodiment, there are multiple supporting ears 500, which are arranged in a circumferential array on the outer wall of the tower section and have two layers along the axial direction; the supporting ears 500 are connected by connecting rods 510, and a support frame can be formed on the outside of the tower section, thereby facilitating the lifting and lowering operations of the tower section.

[0106] In this embodiment, when the number of tower sections needs to be increased, a lifting support mechanism is installed between two adjacent tower sections, so that the tower section located above can be supported and lifted up, so that a new tower section can be installed directly between the two tower sections; conversely, a lifting support mechanism is installed between two tower sections, so that the tower section located above can be lifted up a short distance first, and then the tower section in the middle can be taken out.

[0107] In a preferred embodiment, the lifting support mechanism includes a base plate 520 and a support plate 530 that are parallel to each other; the base plate 520 and the support plate 530 are connected by a hydraulic cylinder 540, and the two sides are respectively connected to the two support frames; the cylinder body of the hydraulic cylinder 540 is fixedly installed on the base plate 520 and is connected to the support plate 530 through a piston rod.

[0108] In this embodiment, the hydraulic cylinder 540 is installed between the base plate 520 and the support plate 530 so that the support plate 530 and the base plate 520 can be lifted and lowered relative to each other, thereby enabling the two tower sections connected thereto to be lifted and lowered relative to each other.

[0109] In a preferred embodiment, a protective component is further provided between the base plate 520 and the support plate 530; the protective component includes three threaded sleeves 521 evenly arranged around the hydraulic cylinder 540; the threaded sleeve 521 is rotatably mounted on the base plate 520, and the axial direction is parallel to the telescopic direction of the hydraulic cylinder 540; a matching threaded rod 531 is provided on the support plate 530 corresponding to the threaded sleeve 521; the threaded rod 531 is fixedly mounted on the support plate 530 and is threadedly connected to the threaded sleeve 521 for auxiliary support of the support plate 530.

[0110] In this embodiment, the protective assembly includes three threaded sleeves 521 evenly arranged around the hydraulic cylinder 540 and threaded rods 531 correspondingly connected to the threaded sleeves; the threaded sleeves 521 are rotatably mounted on the base plate 520, and the threaded rods 531 are fixedly mounted on the support plate 530. By rotating the threaded sleeves 521, the relative displacement between the support plate 530 and the base plate 520 can also be driven; when the hydraulic cylinder 540 is raised and lowered, the threaded sleeves 521 and the threaded rods 531 also perform telescopic movement, thereby preventing loss of control due to hydraulic cylinder failure.
