Description

Technical Field

[0001] The present application relates to the field of chemical distillation, and in particular to a modular fast-assembly type oil refining tower. Background Art

[0002] In the oil refining industry, the refinery tower is one of the core equipment. Its main function is to carry out a series of complex process treatments such as distillation and cracking of crude oil to obtain petroleum products of different fractions such as gasoline, diesel, kerosene, and various chemical raw materials.

[0003] Packed oil refining tower is one of the main forms of oil refining tower, and the packing is the core part of the packed oil refining tower. Common types of packing include Raschig rings, ball rings, step rings, etc. Packed oil refining tower uses the full contact between gas and liquid phases on the surface of the packing to achieve mass transfer and heat transfer. When the raw material enters the tower from the middle or upper part of the tower, the liquid flows downward along the surface of the packing under the action of gravity. At the same time, the gas enters from the bottom of the tower and flows upward evenly through the gas distribution device. In the packing layer, the gas and liquid phases are fully in contact on the surface and gaps of the packing. Due to the different equilibrium concentrations of each component in the gas and liquid phases, the different components in the oil product are mass transferred between the gas and liquid.

[0004] However, when filling the traditional oil refinery tower, the inventor found the following problems: First, bulk fillers are cumbersome to load and difficult to maintain effective compaction; Secondly, under special process conditions such as high temperature and high pressure, how to ensure that the packing maintains a good compression state during long-term operation to avoid loosening or displacement due to temperature and pressure fluctuations. Summary of the invention

[0005] In order to solve the problem of packing of traditional oil refinery towers and ensure the stable performance of the oil refinery tower, the present application provides a modular fast-assembly oil refinery tower.

[0006] The present application provides a modular fast-assembly oil refining tower, which adopts the following technical solution: A modular fast-assembly type oil refining tower, comprising: Multiple tower sections, coaxially arranged vertically; Multiple telescopic packing cylinders are coaxially plugged into each tower cylinder to accommodate bulk packing; A lower limiting member is arranged at the lower side of the inner wall of the tower barrel and is used to limit the position of the bottom of the filling barrel in the tower barrel; A plurality of connecting rings are coaxially arranged between adjacent towers for connecting adjacent towers, wherein the inner diameter of the connecting ring is smaller than the inner diameter of the tower, and the connecting ring extends to the lower side of the inner part of the tower and uniformly forms a plurality of elastic pressing sheets whose outer sides can abut against the inner peripheral wall of the tower; A plurality of elastic plugs are evenly arranged on the upper side of the inner peripheral wall of the tower, wherein the elastic plugs are normally kept protruding from the inner peripheral wall of the tower and can be retracted into the inner peripheral wall of the tower after being compressed; By rotating the tower barrel and the connecting ring relative to each other, the elastic plug can be gradually inserted between the elastic pressing sheet and the connecting ring, so that the free end of the elastic pressing sheet is bent downward, thereby pressing the upper side of the filling barrel to compress the filling in the filling barrel.

[0007] By adopting the above scheme, the packing is first filled and placed in the packing tube. Then the packing tube is installed. During this process, first, the elastic plug column that squeezes the inner wall of the tower tube retracts to the inner wall of the tower tube, and second, the packing tube is inserted into the tower tube so that the bottom of the packing tube is received by the lower limiting member. Then install the connecting ring and place it on the upper side of the tower. Through the interference between multiple elastic pressing plates and the inner wall of the tower, the connecting ring and the tower can be coaxially positioned. Then rotate the connecting ring. At this time, the elastic plug column has protruded from the inner wall of the tower due to the elastic force. As the connecting ring rotates, the elastic plug column is gradually inserted between the elastic pressing plate and the connecting ring from one side. The movable end of the elastic pressing plate, that is, the end not connected to the connecting ring, will gradually bend downward and press on the upper side of the packing tube, thereby continuously squeezing the packing tube. Then fix the connecting ring and the tower, and then connect the upper tower to the upper side of the connecting ring. Repeat the above steps to complete the installation of the packing barrel of this section of the tower. In this way, the setting of the elastic pressing plate, on the one hand, the modular structure makes it easy to load the packing and keep it in a compressed state. On the other hand, it can be kept in operation. Under special process conditions such as high temperature and high pressure, the elastic pressing plate's own elastic pressure can keep the packing in a good compressed state during long-term operation to avoid loosening or displacement due to temperature and pressure fluctuations. In summary, the stable performance of the refinery tower is guaranteed.

[0008] Optionally, the packing tube comprises: Two grille plates are coaxially arranged, and the lower side of the lower grille plate abuts against the lower limiting member; The two ends of the telescopic net cylinder are respectively fixed on two grille plates.

[0009] By adopting the above technical solution, the bulk filler can be filled between the two grid plates and the telescopic mesh cylinder to realize the load-bearing of the bulk filler, and then the bulk filler can be conveniently put into the tower as a whole.

[0010] Optionally, also include: A top rod is vertically slidable in the wall of the tower, and the lower end of the top rod can extend out of the lower end of the tower; A swinging pressure plate, one end of which is hinged to the top rod; The inner peripheral wall of the filling cylinder is formed with a first groove body for accommodating the swing pressure plate; When the lower end of the tower barrel contacts the connecting ring, the upward movement of the top rod will push the swinging pressure plate to contact the upper side of the first trough body and swing toward the inner side of the tower barrel until the swinging pressure plate is pressed against the upper side of the lower grille plate.

[0011] By adopting the above technical solution, after the packing tube is installed in the tower, the lower side of the lower grid plate of the telescopic mesh tube abuts against the lower limiting piece, and then when the tower is installed on the upper side of the connecting ring, the connecting ring pushes the top rod upward in the opposite direction, and the top rod moves upward to push the upper side of the swinging pressure plate to abut against the upper side of the first trough body, and makes the swinging pressure plate swing toward the inside of the tower until the swinging pressure plate is pressed against the upper side of the lower grid plate, thereby realizing the firm positioning of the lower side of the packing tube in the packing tube to ensure the stable performance of the refinery tower.

[0012] Optionally, L-shaped plug plates are formed on both sides of the connecting ring; Both ends of the tower are formed with L-shaped slots; The connection ring can be rotated to enable the L-shaped plug plate to be inserted into the L-shaped slot to limit the tower from vertically separating from the connection ring.

[0013] By adopting the above technical solution, when installing the connecting ring, the two L-shaped plug plates of the connecting ring are respectively inserted into the L-shaped slots of the upper and lower towers, and then the connecting ring is rotated to fully insert the L-shaped plug plates into the L-shaped slots, thereby limiting the tower from detaching from the connecting ring in the vertical direction.

[0014] Optionally, also include: An upper limiting member is fixed to the lower side of the tower; The distributor is coaxially plugged into the tower and can abut against the upper limit piece; A swinging top plate, hinged to the top rod; When the lower end of the tower barrel contacts the connecting ring, the upward movement of the top rod will push the swing top plate toward the inside of the tower barrel to swing tightly against the lower side of the distributor.

[0015] By adopting the above technical solution, when installing the distributor, after the distributor is inserted into the tower, the tower is installed on the upper side of the connecting ring, and the top rod moves vertically upward, the swing top plate can be pushed to swing outward and press against the distributor, so that the distributor is stably fixed between the upper limiting member and the swing top plate, thereby achieving the fixation of the distributor.

[0016] Optionally, a first elastic member is provided between the swing pressure plate and the push rod; The first elastic force pushes the free end of the swinging pressure plate to retract into the first slot body.

[0017] By adopting the above technical solution, the first elastic member pushes the swinging pressure plate to retract into the first groove body to ensure that when the packing tube is inserted into the tower tube, the swinging pressure plate does not interfere with the installation of the packing tube. After the installation of the packing tube is completed, the top rod moves upward and can push the swinging pressure plate to press on the upper side of the grid plate of the packing tube to limit the lower side position of the packing tube.

[0018] Optionally, a second elastic member is provided between the swing top plate and the top rod; The second elastic member keeps pushing the outer end portion of the swing top plate to protrude from the inner wall of the tower.

[0019] By adopting the above technical solution, under normal conditions, the outer end of the swing top plate protrudes from the inner wall of the tower. When the distributor is pushed from bottom to top to be installed inside the tower, the peripheral wall of the distributor can automatically push the swing top plate back into the inner wall of the tower as the distributor is pushed. When the distributor moves to the upper side of the swing top plate, the outer end of the swing top plate is pushed by the second elastic member to protrude from the inner wall of the tower again. Then, when the distributor falls, it will contact the upper side of the swing top plate to prevent the distributor from falling from the lower end of the tower. After the distributor is installed, when the tower is placed on the connecting ring, the top rod moves vertically upward, which pushes the swing top plate to swing outward again and press against the distributor, so that the distributor is stably fixed between the upper limiting member and the swing top plate to achieve the fixation of the distributor.

[0020] Optionally, both ends of the tower are formed with flange rings whose outer diameter is larger than the outer diameter of the tower; Positioning rings with the same thickness as the flange ring are formed on both sides of the connecting ring, and the outer diameter of the flange ring is the same as the inner diameter of the positioning ring.

[0021] By adopting the above technical solution, the flange ring and the positioning ring are used in cooperation, so that a close cooperation between the tower and the connecting ring can be achieved.

[0022] Optionally, the circumferential wall of the positioning ring is radially penetrated with connecting bolts; The flange circumferential wall is formed with screw holes; The end of the connecting bolt can be screwed into any screw hole.

[0023] By adopting the above technical solution, the flange ring can be connected to any screw hole of the flange ring by connecting the connecting bolts, so as to achieve the connection between the flange ring and the positioning ring, thereby achieving the firm fixation of the adjacent towers and the connecting ring.

[0024] Optionally, a positioning convex point is formed on the lower limiting member, and a positioning groove is formed on the lower side of the lower grid plate of the filling cylinder; The positioning protrusion cooperates with the positioning groove to limit the rotation of the filling cylinder relative to the tower cylinder.

[0025] By adopting the above technical solution, the positioning protrusion cooperates with the positioning groove to limit the rotation of the packing tube relative to the tower tube, which can further improve the stability of the packing tube during operation.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. First, fill the packing and place it in the packing tube. Then install the packing tube. During this process, first, the elastic plug column that squeezes the inner wall of the tower tube retracts to the inner wall of the tower tube, and second, the packing tube is inserted into the tower tube so that the bottom of the packing tube is supported by the lower limiter. Then install the connecting ring and place it on the upper side of the tower. Through the interference between multiple elastic pressing plates and the inner wall of the tower, the connecting ring and the tower can be coaxially positioned. Then rotate the connecting ring. At this time, the elastic plug column has protruded from the inner wall of the tower due to the elastic force. As the connecting ring rotates, the elastic plug column is gradually inserted between the elastic pressing plate and the connecting ring from one side. The movable end of the elastic pressing plate, that is, the end not connected to the connecting ring, will gradually bend downward and press on the upper side of the packing tube, thereby continuously squeezing the packing tube. Then fix the connecting ring and the tower, and then connect the upper tower to the upper side of the connecting ring. Repeat the above steps to complete the installation of the packing barrel of this section of the tower. In this way, the setting of the elastic pressing plate, on the one hand, the modular structure makes it easy to load the packing and keep it in a compressed state. On the other hand, it can be kept in operation. Under special process conditions such as high temperature and high pressure, the elastic pressing plate's own elastic pressure can keep the packing in a good compressed state during long-term operation to avoid loosening or displacement due to temperature and pressure fluctuations. In summary, the stable performance of the refinery tower is guaranteed.

[0027] 2. After the packing tube is installed into the tower, the lower side of the lower grid plate of the telescopic mesh tube contacts the lower limit piece. Then, when the tower is installed on the upper side of the connecting ring, the connecting ring pushes the top rod upward in the opposite direction. The top rod moves upward to push the upper side of the swing pressure plate to contact the upper side of the first trough body, and makes the swing pressure plate swing toward the inside of the tower until the swing pressure plate is pressed on the upper side of the lower grid plate, so as to achieve the firm positioning of the lower side of the packing tube in the packing tube to ensure the stable performance of the refinery tower.

[0028] 3. When installing the distributor, after inserting the distributor into the tower and installing the tower on the upper side of the connecting ring, the top rod moves vertically upward, which can push the swing top plate to swing outward and press against the distributor, so that the distributor is stably fixed between the upper limit piece and the swing top plate to achieve the fixation of the distributor.

DETAILED DESCRIPTION

[0031] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0032] The inventors of the present application have discovered that the following problems exist when filling conventional refinery tower packing: first, bulk packing is troublesome to fill and difficult to maintain effective compression; second, under special process conditions such as high temperature and high pressure, how to ensure that the packing maintains a good compression state during long-term operation to avoid loosening or displacement due to temperature and pressure fluctuations.

[0033] To this end, the present application mainly adopts a modular fast-assembly oil refining tower, which achieves a modular structure, making it easy to load the filler and able to maintain a compacted state. Especially under special process conditions such as high temperature and high pressure, the elastic pressure of the elastic pressing sheet can keep the filler in a good compacted state during long-term operation, avoiding loosening or displacement due to temperature and pressure fluctuations, thereby ensuring the stable performance of the oil refining tower. The present application is described in detail below.

[0034] The embodiment of the present application discloses a modular quick-assembly type oil refining tower.

[0035] Reference Figure 1 A modular fast-assembly oil refining tower comprises a tower top 1, a tower body and a tower bottom 2 which are connected to each other. A water distributor 11 is fixed in the tower top 1 for delivering liquid into the oil refining tower and evenly distributing it in the tower body.

[0036] Reference Figure 1 and Figure 2 The tower body includes multiple sections of tower tubes 3, and the structures of the multiple sections of tower tubes 3 are the same. Each section of the tower tube 3 is filled with a packing tube 4, and the packing tube 4 includes two grid plates 41 and a telescopic net tube 42 coaxially fixed between the two grid plates 41. The outer diameter of the two grid plates 41 is the same as the inner diameter of the tower tube 3, and the middle part of the upper grid plate 41 is provided with a net cover 411 in a detachable manner. The net cover 411 can be connected to the grid plate 41 in the direction of bolt connection or thread connection, so that the grid plate 41 at the top of the packing tube 4 can be opened to facilitate the filling of the packing. The outer diameter of the telescopic net tube 42 is slightly smaller than the outer diameter of the grid plate 41. The telescopic net tube 42 includes three sections of hard net tubes, and the upper and lower net tubes are respectively fixed to the adjacent sides of the two grid plates 41, and the middle net tube is sleeved on the adjacent ends of the upper and lower net tubes, and the adjacent ends of the upper and lower net tubes are protruding with a card block, and the card block slides vertically on the middle net tube, thereby realizing the telescopicity of the telescopic net tube 42.

[0037] Reference Figure 3 A lower limiting member 31 is formed in the middle and lower part of the tower 3. In this embodiment, the lower limiting member 31 is an annular member protruding from the inner wall of the tower 3. After the filler is loaded into the filling tube 4 and the filling tube 4 is vertically inserted into the tower 3, the lower end of the filling tube 4 can contact the lower limiting member 31 to realize the load-bearing of the filling tube 4.

[0038] Furthermore, a positioning protrusion is formed on the lower limiting member 31 , and a positioning groove is formed on the lower side of the lower grid plate 41 of the filling tube 4 . The positioning protrusion cooperates with the positioning groove to limit the rotation of the filling tube 4 relative to the tower tube 3 .

[0039] Reference Figure 3 and Figure 4 A connecting ring 5 is coaxially arranged between adjacent tower tubes 3, and L-shaped plug plates 51 are formed on the upper and lower sides of the connecting ring 5. L-shaped slots 32 are also formed at the ends of the tower tubes 3. When the connecting ring 5 is placed between two adjacent tower tubes 3, the two L-shaped plug plates 51 are first vertically inserted into the L-shaped slots 32, and then the connecting ring 5 is rotated to fully insert the L-shaped plug plates 51 into the L-shaped slots 32, thereby limiting the tower tubes 3 from being separated from the connecting ring 5 in the vertical direction.

[0040] The upper end of the inner wall of the tower 3 is uniformly formed with a plurality of insertion holes, and elastic plug posts 33 are installed in the insertion holes. The elastic plug posts 33 are arranged along the radial direction of the tower 3. The elastic plug posts 33 can remain protruding from the inner wall of the tower 3 under normal conditions, and the elastic plug posts 33 can retract into the insertion holes of the inner wall of the tower 3 after being compressed. The inner diameter of the connecting ring 5 is smaller than the inner diameter of the tower 3, and a plurality of elastic pressing sheets 52 are formed on the lower side of the connecting ring 5 located inside the tower 3. The plurality of elastic pressing sheets 52 are all arc-shaped and can contact the inner wall of the tower 3. One end of each elastic pressing sheet 52 is fixed to the connecting ring 5, and the other end thereof is a free end.

[0041] When connecting the connecting ring 5 to the tower 3, the tower 3 and the connecting ring 5 are rotated relative to each other, so that one side of the elastic plug 33 can be gradually inserted between the elastic pressing sheet 52 and the connecting ring 5, thereby separating the elastic pressing sheet 52 and the connecting ring 5, so that the free end of the elastic pressing sheet 52 is bent downward, and then presses the upper side of the filling tube 4, thereby squeezing the filling tube 4 to compress the filling inside the filling tube 4.

[0042] When splicing the tower 3 and the connecting ring 5, first fill the filler and place the filler in the filling tube 4. Then install the filling tube 4. During this process, first, the elastic plug 33 that squeezes the inner wall of the tower 3 retracts to the inner wall of the tower 3. Second, insert the filling tube 4 into the tower 3 so that the bottom of the filling tube 4 is supported by the lower limiting member 31. Then install the connecting ring 5 and place the connecting ring 5 on the upper side of the tower 3. Through the interference of multiple elastic pressing sheets 52 with the inner wall of the tower 3, it can be ensured that the connecting ring 5 and the tower 3 are coaxially positioned. Then rotate the connecting ring 5. At this time, the elastic plug 33 has protruded from the inner wall of the tower 3 due to the elastic force. As the connecting ring 5 rotates, the elastic plug 33 is gradually inserted from one side between the elastic pressing sheet 52 and the connecting ring 5. The movable end of the elastic pressing sheet 52, that is, the end not connected to the connecting ring 5, will gradually bend downward and press on the upper side of the filling tube 4, thereby continuously squeezing the filling tube 4. Then fix the connecting ring 5 and the tower 3, and then connect the upper tower 3 to the upper side of the connecting ring 5, and repeat the above steps to complete the installation of the filling tube 4 of this section of the tower 3. In this way, the setting of the elastic pressing piece 52, on the one hand, the modular structure makes it convenient to load the filler and can keep it in a compacted state, and on the other hand, it can be maintained in operation. Under special process conditions such as high temperature and high pressure, the elastic pressing piece 52 itself can keep the filler in a good compacted state during long-term operation to avoid loosening or displacement due to temperature and pressure fluctuations. In summary, the stable performance of the refinery tower is guaranteed.

[0043] Both ends of the tower 3 are formed with flange rings 34 whose outer diameter is larger than that of the tower 3, and both sides of the connecting ring 5 are formed with positioning rings 53 whose thickness is the same as that of the flange ring 34, and the outer diameter of the flange ring 34 is the same as the inner diameter of the positioning ring 53. The flange ring 34 and the positioning ring 53 are used in cooperation, so that the tower 3 and the connecting ring 5 can be closely matched. The peripheral wall of the positioning ring 53 is evenly penetrated with a plurality of connecting bolts 54, and the plurality of connecting bolts 54 are arranged along the radial direction of the positioning ring 53. The peripheral wall of the flange ring 34 is also evenly formed with a plurality of screw holes 35, and the number of the screw holes 35 is greater than the number of the connecting bolts 54. The end of the connecting bolt 54 can be screwed to any screw hole 35, so that the connecting ring 5 can remain connected after rotating at different angles relative to the tower 3. In this way, after the tower 3 and the connecting ring 5 are connected, the connecting bolt 54 is connected to any screw hole 35 of the flange ring 34, so that the flange ring 34 and the positioning ring 53 can be connected, thereby realizing the firm fixation of the adjacent towers 3 and the connecting ring 5.

[0044] Reference Figure 5 There are multiple top rods 6 that slide vertically in the wall of the tower 3. The top rods 6 slide vertically, so that the lower ends of the top rods 6 can extend out of the lower end of the tower 3. The inner wall of the tower 3 is formed with a first groove body 36. The first groove body 36 contains a swinging pressure plate 61. One end of the swinging pressure plate 61 is hinged to the top rod 6. A first elastic member is arranged between the swinging pressure plate 61 and the top rod 6. The first elastic member can be a torsion spring. The first elastic member pushes the free end of the swinging pressure plate 61 to retract into the first groove body 36.

[0045] Under normal conditions, the first elastic member pushes the swinging pressure plate 61 to retract into the first slot body 36, which can ensure that when the packing tube 4 is inserted into the tower tube 3, the swinging pressure plate 61 does not interfere with the installation of the packing tube 4. After the connection of the tower tube 3 is completed, the lower side of the lower grid plate 41 of the telescopic mesh tube 42 abuts against the lower limiting member 31. Then, when the tower tube 3 is installed on the upper side of the connecting ring 5, the connecting ring 5 pushes the top rod 6 upward in the opposite direction. The top rod 6 moves upward to push the upper side of the swinging pressure plate 61 to abut against the upper side of the first slot body 36, and makes the swinging pressure plate 61 swing toward the inside of the tower tube 3 until the swinging pressure plate 61 is pressed against the upper side of the lower grid plate 41, so as to realize the firm positioning of the lower side of the packing tube 4 in the packing tube 4 to ensure the stable performance of the refining tower.

[0046] Furthermore, a distributor 7 is provided inside the tower 3 below the corresponding filling tube 4. The distributor 7 is a trough-type distributor 7, which is coaxially inserted into the tower 3. An upper limiting member 37 is formed on the upper side of the inner wall of the tower 3 corresponding to the lower limiting member 31. In this embodiment, the upper limiting member 37 is also a ring-shaped member protruding from the inner wall of the tower 3. When the distributor 7 is pushed upward, the upper side of the distributor 7 can contact the upper limiting member 37.

[0047] A plurality of second slots 38 are formed on the inner wall of the tower 3 corresponding to the lower part of the distributor 7. The second slots 38 correspond to the position of the mandrel 6, and a swinging top plate 62 is arranged in each of the second slots 38. One end of the swinging top plate 62 is also hinged to the mandrel 6, and the swinging top plate 62 can swing within a certain range relative to the mandrel 6. A second elastic member is arranged between the swinging top plate 62 and the mandrel 6. The second elastic member can also be a torsion spring. The second elastic member keeps pushing the outer end of the swinging top plate 62 to protrude from the inner wall of the tower 3 under normal conditions.

[0048] Under normal conditions, the outer end of the swing top plate 62 protrudes from the inner wall of the tower 3. When the distributor 7 is pushed from bottom to top to be installed inside the tower 3, the peripheral wall of the distributor 7 can automatically push the swing top plate 62 back into the inner wall of the tower 3 as the distributor 7 is pushed. When the distributor 7 moves to the upper side of the swing top plate 62, the outer end of the swing top plate 62 is pushed by the second elastic member to protrude from the inner wall of the tower 3 again. Then, when the distributor 7 falls, it will contact the upper side of the swing top plate 62 to prevent the distributor 7 from falling from the lower end of the tower 3. After the distributor 7 is installed, when the tower 3 is placed on the connecting ring 5, the top rod 6 moves vertically upward, and the upper side of the swing top plate contacts the upper side of the second slot body 38. When the swing top plate 62 is pushed to swing outward to the limit position again, it will press against the lower side of the distributor 7, so that the distributor 7 is stably fixed between the upper limit member 37 and the swing top plate 62 to achieve the fixation of the distributor 7.

[0049] The implementation principle of a modular fast-assembly oil refining tower in the embodiment of the present application is: When splicing the refinery tower, first fill the filler and place the filler in the filler tube 4. Then install the filler tube 4. During this process, first, the elastic plug 33 that squeezes the inner wall of the tower tube 3 retracts to the inner wall of the tower tube 3. Second, insert the filler tube 4 into the tower tube 3 so that the bottom of the filler tube 4 is supported by the lower limiter 31. Then install the connecting ring 5 and place the connecting ring 5 on the upper side of the tower tube 3. Through the interference of multiple elastic pressing plates 52 with the inner wall of the tower tube 3, it can be ensured that the connecting ring 5 and the tower tube 3 are coaxially positioned. Then rotate the connecting ring 5. At this time, the elastic plug 33 has protruded from the inner wall of the tower tube 3 due to the elastic force; and as the connecting ring 5 rotates, the elastic plug 33 is gradually inserted from one side between the elastic pressing plate 52 and the connecting ring 5. The movable end of the elastic pressing plate 52, that is, the end not connected to the connecting ring 5, will gradually bend downward and press on the upper side of the filler tube 4, thereby continuously squeezing the filler tube 4, and then fix the connecting ring. 5 and the tower 3, and then connect the upper tower 3 to the upper side of the connecting ring 5, and repeat the above steps to complete the installation of the filling tube 4 of this section of the tower 3. In this way, the setting of the elastic pressing piece 52, on the one hand, the modular structure makes it convenient to load the filler and can keep it in a compacted state, and on the other hand, it can be maintained in operation. Under special process conditions such as high temperature and high pressure, the elastic pressing piece 52 itself can keep the filler in a good compacted state during long-term operation to avoid loosening or displacement due to temperature and pressure fluctuations. In summary, the stable performance of the refinery tower is guaranteed.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
