Description

Technical Field

[0001] This application relates to the field of chemical rectification, and particularly to a modular and quickly assembled oil refining tower. Background Art

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

[0003] The packed oil refining tower is one of the main forms of oil refining towers, and the packing is the core part of the packed oil refining tower. Common types of packing include Raschig rings, Pall rings, cascade rings, etc. The packed oil refining tower utilizes the full contact of gas-liquid two phases on the surface of the packing to achieve the mass transfer and heat transfer processes. 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 uniformly flows upward through the gas distribution device. In the packing layer, the gas-liquid two phases are in full contact on the surface and voids of the packing. Due to the different equilibrium concentrations of each component in the gas-liquid two phases, different components in the oil product perform mass transfer between the gas and liquid.

[0004] However, when filling the packing of the traditional oil refining tower, the inventor found the following problems:

[0005] Firstly, the bulk packing is troublesome to fill and it is difficult to maintain effective compaction.

[0006] Secondly, under special process conditions such as high temperature and high pressure, how to ensure that the packing maintains a good compaction state during long-term operation and avoid loosening or displacement due to temperature and pressure fluctuations. Summary of the Invention

[0007] In order to solve the problem of packing filling in the traditional oil refining tower and ensure the stable performance of the oil refining tower, this application provides a modular and quickly assembled oil refining tower.

[0008] A modular and quickly assembled oil refining tower provided by this application adopts the following technical solutions:

[0009] A modular and quickly assembled oil refining tower includes:

[0010] Multiple tower barrels arranged coaxially and vertically;

[0011] Multiple telescopic packing barrels coaxially inserted into each tower barrel for accommodating bulk packing;

[0012] A lower limiting member arranged on the lower side of the inner wall of the tower barrel for limiting the position of the bottom of the packing barrel in the tower barrel;

[0013] A plurality of connecting rings are coaxially arranged between adjacent tower barrels and are used to connect adjacent tower barrels. The inner diameter of the connecting ring is smaller than the inner diameter of the tower barrel, and a plurality of elastic pressing pieces whose outer sides can abut against the inner peripheral wall of the tower barrel are uniformly formed on the lower side of the part where the connecting ring extends into the tower barrel;

[0014] A plurality of elastic insertion posts are uniformly arranged on the upper side of the inner peripheral wall of the tower barrel. The elastic insertion posts normally protrude from the inner peripheral wall of the tower barrel and can retract into the inner peripheral wall of the tower barrel after being pressed;

[0015] Rotating the tower barrel and the connecting ring relative to each other can gradually insert the elastic insertion posts between the elastic pressing pieces and the connecting ring, so that the free ends of the elastic pressing pieces are bent downward, and then the upper side of the packing cylinder is pressed to compact the packing in the packing cylinder.

[0016] By adopting the above scheme, first, the packing is filled and placed in the packing cylinder. Then the packing cylinder is installed. In this process, first, the elastic insertion posts on the inner wall of the tower barrel are retracted into the inner wall of the tower barrel under extrusion. Second, the packing cylinder is inserted into the tower barrel, and the bottom of the packing cylinder is received by the lower limiting member. Then the connecting ring is installed and placed on the upper side of the tower barrel. By the abutment of the plurality of elastic pressing pieces against the inner wall of the tower barrel, the coaxial positioning of the connecting ring and the tower barrel can be ensured. Then the connecting ring is rotated. At this time, the elastic insertion posts protrude from the inner peripheral wall of the tower barrel due to the elastic force; with the rotation of the connecting ring, the elastic insertion posts gradually insert between the elastic pressing pieces and the connecting ring from one side, and the movable end of the elastic pressing piece, that is, the end not connected to the connecting ring, will gradually bend downward and press on the upper side of the packing cylinder, so as to continuously extrude the packing cylinder. Then the connecting ring and the tower barrel are fixed. Then the upper layer of the tower barrel is connected to the upper side of the connecting ring, and the above steps are repeated to complete the installation of the packing barrel of this section of the tower barrel. In this way, the setting of the elastic pressing piece, on the one hand, the modular structure makes the packing convenient to load and can maintain the compacted state. On the other hand, during the operation, under special process conditions such as high temperature and high pressure, the self-elastic pressing of the elastic pressing piece can keep the packing in a good compacted state during long-term operation, avoiding loosening or displacement due to temperature and pressure fluctuations. In summary, the performance of the refining tower is guaranteed to be stable.

[0017] Optionally, the packing cylinder includes:

[0018] Two grid plates are coaxially arranged, and the lower side of the lower grid plate abuts against the lower limiting member;

[0019] A telescopic mesh cylinder, the two ends of which are respectively fixed to the two grid plates.

[0020] By adopting the above technical scheme, the bulk packing can be filled between the two grid plates and the telescopic mesh cylinder to realize the loading of the bulk packing, and then the bulk packing can be conveniently put into the tower barrel as a whole.

[0021] Optionally, it further includes:

[0022] The ejector rod slides vertically within the tower barrel wall and its lower end can extend out of the lower end of the tower barrel.

[0023] The swing pressing plate has one end hinged to the ejector rod.

[0024] A first groove is formed on the inner peripheral wall of the packing cylinder for accommodating the swing pressing plate.

[0025] When the lower end of the tower barrel abuts against the connecting ring, the upward movement of the ejector rod will push the swing pressing plate to abut against the upper side of the first groove and swing towards the inner side of the tower barrel until the swing pressing plate presses against the upper side of the lower grid plate.

[0026] By adopting the above technical solution, after the packing cylinder is installed in the tower barrel, the lower side of the lower grid plate of the telescopic mesh cylinder abuts against the lower limiting member. Then, when the tower barrel is installed on the upper side of the connecting ring, the connecting ring reversely pushes the ejector rod to move upward. The upward movement of the ejector rod pushes the upper side of the swing pressing plate to abut against the upper side of the first groove and makes the swing pressing plate swing towards the inner side of the tower barrel until the swing pressing plate presses against the upper side of the lower grid plate, realizing the firm positioning of the lower side of the packing cylinder inside the packing cylinder to ensure the stable performance of the refining tower.

[0027] Optionally, L-shaped insertion plates are formed on both sides of the connecting ring.

[0028] L-shaped slots are formed at both ends of the tower barrel.

[0029] The rotation of the connecting ring can make the L-shaped insertion plates be inserted into the L-shaped slots to limit the vertical detachment of the tower barrel from the connecting ring.

[0030] By adopting the above technical solution, when installing the connecting ring, the two L-shaped insertion plates of the connecting ring are respectively inserted into the L-shaped slots of the upper and lower tower barrels, and then the connecting ring is rotated to completely insert the L-shaped insertion plates into the L-shaped slots, thereby restricting the tower barrel from detaching from the connecting ring in the vertical direction.

[0031] Optionally, it further includes:

[0032] The upper limiting member is fixed to the lower side inside the tower barrel.

[0033] The distributor is coaxially inserted into the tower barrel and can abut against the upper limiting member.

[0034] The swing top plate is hinged to the ejector rod.

[0035] When the lower end of the tower barrel abuts against the connecting ring, the upward movement of the ejector rod will push the swing top plate to swing towards the inside of the tower barrel to tightly press against the lower side of the distributor.

[0036] By adopting the above technical solution, when installing the distributor, after inserting the distributor into the tower barrel and then installing the tower barrel above the connecting ring, the ejector rod moves vertically upward, which can push the swing top plate to swing outward and press tightly 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.

[0037] Optionally, a first elastic member is provided between the swing pressing plate and the ejector rod;

[0038] The first elastic member pushes the free end of the swing pressing plate to retract into the first groove body.

[0039] By adopting the above technical solution, the first elastic member pushes the swing pressing plate to retract into the first groove body to ensure that when the packing cylinder is inserted into the tower barrel, the swing pressing plate is prevented from interfering with the installation of the packing cylinder. After the installation of the packing cylinder is completed, the ejector rod moves upward, which can also push the swing pressing plate to press on the upper side of the grille plate of the packing cylinder to limit the position of the lower side of the packing cylinder.

[0040] Optionally, a second elastic member is provided between the swing top plate and the ejector rod;

[0041] The second elastic member keeps pushing the outer end part of the swing top plate to protrude from the inner wall of the tower barrel.

[0042] 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 barrel. When the distributor is pushed from bottom to top and installed inside the tower barrel, with the push of the distributor, the peripheral wall of the distributor can automatically push the swing top plate to retract into the inner wall of the tower barrel. 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 barrel again. Furthermore, 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 barrel. After the installation of the distributor is completed, when the tower barrel is placed on the connecting ring, the ejector rod moves vertically upward, which then pushes the swing top plate to swing outward and press tightly 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.

[0043] Optionally, flange rings with an outer diameter larger than the outer diameter of the tower barrel are formed at both ends of the tower barrel;

[0044] Positioning rings with the same thickness as the flange rings 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.

[0045] By adopting the above technical solution, the cooperation of the flange ring and the positioning ring can achieve the tight fit between the tower barrel and the connecting ring.

[0046] Optionally, connecting bolts are radially inserted through the peripheral wall of the positioning ring;

[0047] Screw holes are formed on the peripheral wall of the flange ring;

[0048] The end of the connecting bolt can be screwed into any one of the screw holes.

[0049] By adopting the above technical solution, connecting the connecting bolt to any screw hole of the flange ring can realize the connection between the flange ring and the positioning ring, thereby realizing the firm fixation of the adjacent tower barrels and the connecting ring.

[0050] Optionally, positioning bumps are formed on the lower limiting member, and positioning grooves are formed on the lower side of the lower grid plate of the packing cylinder;

[0051] The cooperation between the positioning bumps and the positioning grooves can limit the rotation of the packing cylinder relative to the tower barrel.

[0052] By adopting the above technical solution, the cooperation between the positioning bumps and the positioning grooves to limit the rotation of the packing cylinder relative to the tower barrel can further improve the stability of the packing cylinder during operation.

[0053] In summary, the present application includes at least one of the following beneficial technical effects:

[0054] 1. First, fill the packing and place the packing in the packing cylinder. Then install the packing cylinder. During this process, first, the elastic insertion posts on the inner wall of the tower barrel retract into the inner wall of the tower barrel, and second, insert the packing cylinder into the tower barrel so that the bottom of the packing cylinder is received by the lower limiting member. Then install the connecting ring, place the connecting ring on the upper side of the tower barrel, and the contact between the plurality of elastic pressing pieces and the inner wall of the tower barrel can ensure the coaxial positioning of the connecting ring and the tower barrel. Then rotate the connecting ring. At this time, the elastic insertion posts protrude from the inner peripheral wall of the tower barrel due to the elastic force; as the connecting ring rotates, the elastic insertion posts gradually insert between the elastic pressing pieces and the connecting ring from one side. The movable end of the elastic pressing piece, that is, the end not connected to the connecting ring, will gradually bend downward and press on the upper side of the packing cylinder, thereby continuously squeezing the packing cylinder. Then fix the connecting ring and the tower barrel. Then connect the upper layer of the tower barrel to the upper side of the connecting ring, and repeat the above steps to complete the installation of the packing barrel of this section of the tower barrel. In this way, the setting of the elastic pressing piece, on the one hand, the modular structure makes the filling of the packing convenient and can maintain the pressing state. On the other hand, during operation, under special process conditions such as high temperature and high pressure, the self-elastic pressing of the elastic pressing piece can keep the packing in a good pressing state during long-term operation, avoiding loosening or displacement due to temperature and pressure fluctuations. In summary, the performance of the refining tower is guaranteed to be stable.

[0055] 2. After the packing cylinder is installed into the tower barrel, the lower side of the lower grid plate of the telescopic mesh cylinder abuts against the lower limiting member. Then, when the tower barrel is installed on the upper side of the connecting ring, the connecting ring pushes the ejector rod upward in the reverse direction. The ejector rod moves upward to push the upper side of the swing pressing plate to abut against the upper side of the first groove body, and makes the swing pressing plate swing towards the inner side of the tower barrel until the swing pressing plate presses against the upper side of the lower grid plate, realizing the firm fixation of the lower side of the packing cylinder inside the packing cylinder to ensure the stable performance of the oil refining tower.

[0056] 3. When installing the distributor, after the distributor is inserted into the tower barrel and the tower barrel is installed on the upper side of the connecting ring, the ejector rod moves vertically upward, then it can push the swing top plate to swing outward and press tightly against the distributor, so that the distributor is stably fixed between the upper limiting member and the swing top plate to realize the fixation of the distributor.

Detailed Embodiments

[0063] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings. 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 labor, and these embodiments are also within the protection scope of the present invention.

[0064] The inventors of the present application have found that the following problems exist during the packing of traditional refinery tower packings: On the one hand, the bulk packing is troublesome to pack and it is difficult to maintain effective compaction; on the other hand, under special process conditions such as high temperature and high pressure, how to ensure that the packing maintains a good compaction state during long-term operation and avoid loosening or displacement due to temperature and pressure fluctuations.

[0065] Therefore, the present application mainly adopts a modular and quickly assembled refinery tower, achieving a modular structure, making the packing convenient to pack and capable of maintaining a compacted state. Especially under special process conditions such as high temperature and high pressure, the self-elastic pressing of the elastic pressing piece can keep the packing 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 refinery tower. The following is a detailed description of the present application.

[0066] An embodiment of the present application discloses a modular and quickly assembled refinery tower.

[0067] Referring to Figure 1 , a modular and quickly assembled refinery tower includes a tower top 1, a tower body, and a tower bottom 2 that are connected to each other. A water distributor 11 is fixed inside the tower top 1 for sending liquid into the refinery tower and evenly dispersing it inside the tower body.

[0068] Referring to Figure 1 and Figure 2 , the tower body includes multiple tower sections 3, and the structures of the multiple tower sections 3 are the same. Each tower section 3 is filled with a packing cylinder 4. The packing cylinder 4 includes two grid plates 41 and a telescopic mesh cylinder 42 coaxially fixed between the two grid plates 41. The outer diameters of the two grid plates 41 are the same as the inner diameter of the tower section 3. A mesh cover 411 is detachably arranged in the middle of the upper grid plate 41. The mesh cover 411 can be connected to the grid plate 41 by bolt connection or in a threaded connection direction to enable the upper grid plate 41 of the packing cylinder 4 to be opened to facilitate the filling of the packing. The outer diameter of the telescopic mesh cylinder 42 is slightly smaller than the outer diameter of the grid plate 41. The telescopic mesh cylinder 42 includes three hard mesh cylinders. The upper and lower mesh cylinders are respectively fixed to the adjacent sides of the two grid plates 41. The middle mesh cylinder is sleeved on the adjacent ends of the upper and lower mesh cylinders, and clamping blocks are convexly formed at the adjacent ends of the upper and lower mesh cylinders. The clamping blocks vertically slide in the middle mesh cylinder, thereby realizing the telescopic property of the telescopic mesh cylinder 42.

[0069] Referring to Figure 3 , a lower limiting member 31 is formed in the middle and lower part of the tower section 3. In this embodiment, the lower limiting member 31 is an annular member convexly formed on the inner wall of the tower section 3. After the packing is filled in the packing cylinder 4 and the packing cylinder 4 is vertically inserted into the tower section 3, the lower end of the packing cylinder 4 can abut against the lower limiting member 31 to realize the bearing of the packing cylinder 4.

[0070] Further, positioning bumps are formed on the lower limiting member 31, and positioning grooves are formed on the lower side of the lower grid plate 41 of the filler cylinder 4. The cooperation between the positioning bumps and the positioning grooves can limit the rotation of the filler cylinder 4 relative to the tower barrel 3.

[0071] Referring to Figure 3 and Figure 4 , connecting rings 5 are coaxially arranged between adjacent tower barrels 3. L-shaped insertion plates 51 are formed on both the upper and lower sides of the connecting ring 5, and L-shaped slots 32 are also formed at the ends of the tower barrels 3. When the connecting ring 5 is placed between two adjacent tower barrels 3, first, the two L-shaped insertion plates 51 are vertically inserted into the L-shaped slots 32, and then the connecting ring 5 is rotated, so that the L-shaped insertion plates 51 can be completely inserted into the L-shaped slots 32, thereby restricting the tower barrel 3 from detaching from the connecting ring 5 in the vertical direction.

[0072] A plurality of jacks are evenly formed at the upper end of the inner peripheral wall of the tower barrel 3, and elastic plug posts 33 are installed in the jacks. The elastic plug posts 33 are arranged along the radial direction of the tower barrel 3. Under normal conditions, the elastic plug posts 33 can protrude from the inner peripheral wall of the tower barrel 3, and the elastic plug posts 33 can retract into the jacks on the inner peripheral wall of the tower barrel 3 after being pressed. The inner diameter of the connecting ring 5 is smaller than the inner diameter of the tower barrel 3, and a plurality of elastic pressing pieces 52 are formed on the lower side of the part of the connecting ring 5 located inside the tower barrel 3. The plurality of elastic pressing pieces 52 are all arc-shaped and can abut against the inner wall of the tower barrel 3. One end of each elastic pressing piece 52 is fixed to the connecting ring 5, and the other end is a free end.

[0073] When connecting the connecting ring 5 and the tower barrel 3, relatively rotating the tower barrel 3 and the connecting ring 5 can gradually insert one side of the elastic plug post 33 between the elastic pressing piece 52 and the connecting ring 5, thereby separating the elastic pressing piece 52 from the connecting ring 5, causing the free end of the elastic pressing piece 52 to bend downward, and further pressing the upper side of the filler cylinder 4, thereby squeezing the filler cylinder 4 to compress the filler in the filler cylinder 4.

[0074] When splicing the tower barrel 3 and the connecting ring 5, first, fill the packing material and place it in the packing cylinder 4. Then install the packing cylinder 4. During this process, first, the elastic plug posts 33 on the inner wall of the tower barrel 3 retract into the inner wall of the tower barrel 3. Second, insert the packing cylinder 4 into the tower barrel 3 so that the bottom of the packing cylinder 4 is received 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 barrel 3. By the contact of the multiple elastic pressing pieces 52 with the inner wall of the tower barrel 3, the coaxial positioning of the connecting ring 5 and the tower barrel 3 can be ensured. Then rotate the connecting ring 5. At this time, the elastic plug posts 33 protrude from the inner peripheral wall of the tower barrel 3 due to the elastic force. As the connecting ring 5 rotates, the elastic plug posts 33 gradually insert between the elastic pressing pieces 52 and the connecting ring 5 from one side. The movable end of the elastic pressing piece 52, that is, the end not connected to the connecting ring 5, will gradually bend downward and press on the upper side of the packing cylinder 4, thereby continuously squeezing the packing cylinder 4. Then fix the connecting ring 5 and the tower barrel 3. Then connect the upper-layer tower barrel 3 to the upper side of the connecting ring 5 and repeat the above steps to complete the installation of the packing cylinder 4 of this section of the tower barrel 3. In this way, the setting of the elastic pressing piece 52, on the one hand, the modular structure makes the filling of the packing material convenient and can maintain the pressing state. On the other hand, during the operation, under special process conditions such as high temperature and high pressure, the self-elastic pressing of the elastic pressing piece 52 can keep the packing material in a good pressing state during long-term operation, avoiding loosening or displacement due to temperature and pressure fluctuations. Overall, it ensures the stable performance of the refining tower.

[0075] Flange rings 34 with an outer diameter larger than that of the tower barrel 3 are formed at both ends of the tower barrel 3. Positioning rings 53 with the same thickness as the flange rings 34 are formed on both sides of the connecting ring 5, and the outer diameter of the flange ring 34 is the same as the inner diameter of the positioning ring 53. The cooperation of the flange ring 34 and the positioning ring 53 can achieve the tight fit between the tower barrel 3 and the connecting ring 5. A plurality of connecting bolts 54 are evenly penetrated through the peripheral wall of the positioning ring 53, and the plurality of connecting bolts 54 are all arranged along the radial direction of the positioning ring 53. A plurality of screw holes 35 are also evenly formed on the peripheral wall of the flange ring 34, and the number of the screw holes 35 is more than the number of the connecting bolts 54. The end of the connecting bolt 54 can be screwed into any one of the screw holes 35 to enable the connecting ring 5 to remain connected after rotating at different angles relative to the tower barrel 3. In this way, after the connection between the tower barrel 3 and the connecting ring 5 is completed, connecting the connecting bolt 54 to any one of the screw holes 35 of the flange ring 34 can realize the connection between the flange ring 34 and the positioning ring 53, thereby realizing the firm fixation of the adjacent tower barrel 3 and the connecting ring 5.

[0076] Refer to Figure 5, there are multiple ejector rods 6 sliding vertically inside the barrel wall of the tower barrel 3. The ejector rods 6 slide vertically, enabling the lower ends of the ejector rods 6 to extend out of the lower end of the tower barrel 3. A first groove 36 is formed on the inner peripheral wall of the tower barrel 3. A swing pressing plate 61 is disposed in the first groove 36. One end of the swing pressing plate 61 is hinged to the ejector rod 6. A first elastic member is provided between the swing pressing plate 61 and the ejector rod 6. The first elastic member can be a torsion spring. The first elastic member pushes the free end of the swing pressing plate 61 to retract into the first groove 36.

[0077] Under normal conditions, the first elastic member pushes the swing pressing plate 61 to retract into the first groove 36, which can ensure that when the packing cylinder 4 is inserted into the tower barrel 3, the swing pressing plate 61 is prevented from interfering with the installation of the packing cylinder 4. After the connection of the tower barrel 3 is completed, the lower side of the lower grid plate 41 of the telescopic mesh cylinder 42 abuts against the lower limiting member 31. Then, when the tower barrel 3 is installed on the upper side of the connecting ring 5, the connecting ring 5 pushes the ejector rod 6 to move upward. The ejector rod 6 moves upward to push the upper side of the swing pressing plate 61 to abut against the upper side of the first groove 36, and makes the swing pressing plate 61 swing towards the inner side of the tower barrel 3 until the swing pressing plate 61 presses against the upper side of the lower grid plate 41, realizing the firm positioning of the lower side of the packing cylinder 4 inside the packing cylinder 4 to ensure the stable performance of the oil refining tower.

[0078] Furthermore, a distributor 7 is also provided inside the tower barrel 3 corresponding to the lower part of the packing cylinder 4. The distributor 7 is a trough-type distributor 7. The distributor 7 is coaxially inserted into the tower barrel 3. An upper limiting member 37 is formed on the inner wall of the tower barrel 3 corresponding to the upper side of the lower limiting member 31. In this embodiment, the upper limiting member 37 is also an annular member protruding from the inner wall of the tower barrel 3. When the distributor 7 is pushed upward, the upper side of the distributor 7 can abut against the upper limiting member 37.

[0079] Multiple second grooves 38 are formed on the inner peripheral wall of the tower barrel 3 corresponding to the lower part of the distributor 7. The second grooves 38 correspond to the positions of the ejector rods 6, and swing top plates 62 are provided in the second grooves 38. One end of each swing top plate 62 is also hinged to the ejector rod 6. The swing top plates 62 can swing relative to the ejector rods 6 within a certain range. A second elastic member is provided between the swing top plates 62 and the ejector rods 6. The second elastic member can also be a torsion spring. The second elastic member normally keeps pushing the outer end portions of the swing top plates 62 to protrude from the inner wall of the tower barrel 3.

[0080] Under normal conditions, the outer end of the swing top plate 62 protrudes from the inner wall of the tower barrel 3. When the distributor 7 is pushed upward and installed inside the tower barrel 3, as the distributor 7 is pushed, the peripheral wall of the distributor 7 can automatically push the swing top plate 62 to retract into the inner wall of the tower barrel 3. 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 barrel 3 again. Furthermore, when the distributor 7 falls, it will abut against the upper side of the swing top plate 62 to prevent the distributor 7 from falling from the lower end of the tower barrel 3. After the installation of the distributor 7 is completed, when the tower barrel 3 is placed on the connecting ring 5, the ejector rod 6 moves vertically upward, and the upper side of the swing top plate abuts against the upper side of the second groove body 38. Then, when the swing top plate 62 is pushed to swing outward to the limit position again, it will be pressed against the lower side of the distributor 7, so that the distributor 7 is stably fixed between the upper limiting member 37 and the swing top plate 62 to realize the fixation of the distributor 7.

[0081] The implementation principle of a modular and quickly assembled oil refining tower according to an embodiment of the present application is as follows:

[0082] When splicing the oil refining tower, first, fill the packing and place the packing in the packing cylinder 4. Then install the packing cylinder 4. In this process, first, the elastic insertion post 33 pressing against the inner wall of the tower barrel 3 retracts into the inner wall of the tower barrel 3. Second, insert the packing cylinder 4 into the tower barrel 3 so that the bottom of the packing cylinder 4 is received 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 barrel 3. By the abutment of a plurality of elastic pressing pieces 52 against the inner wall of the tower barrel 3, it can be ensured that the connecting ring 5 and the tower barrel 3 are coaxially positioned. Then rotate the connecting ring 5. At this time, the elastic insertion post 33 has protruded from the inner peripheral wall of the tower barrel 3 due to the elastic force; as the connecting ring 5 rotates, the elastic insertion post 33 gradually inserts into the space between the elastic pressing piece 52 and the connecting ring 5 from one side. The movable end of the elastic pressing piece 52, that is, the end not connected to the connecting ring 5, will gradually bend downward and press against the upper side of the packing cylinder 4, thereby continuously squeezing the packing cylinder 4. Then fix the connecting ring 5 and the tower barrel 3. Then connect the upper layer of the tower barrel 3 to the upper side of the connecting ring 5 and repeat the above steps to complete the installation of the packing cylinder 4 of this section of the tower barrel 3. In this way, the elastic pressing piece 52 is provided. On the one hand, the modular structure makes the packing easy to load and can maintain the pressed state. On the other hand, during the operation, under special process conditions such as high temperature and high pressure, the self-elastic pressing of the elastic pressing piece 52 can keep the packing in a good pressed state during long-term operation, avoiding loosening or displacement due to temperature and pressure fluctuations. In summary, the performance of the oil refining tower is guaranteed to be stable.

[0083] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
