Description

Technical Field

[0001] The invention relates to the technical field of rapid cooling heat exchangers, in particular to a connector structure for an inlet of a linear rapid cooling heat exchanger. Background Art

[0002] The cracking furnace is a key unit of the ethylene plant. After the cracking raw materials undergo high-temperature cracking in the cracking furnace tube, they enter the quench heat exchanger for rapid cooling to prevent the occurrence of secondary reactions, reduce olefin losses, and recover heat energy to generate steam. With the development of ethylene cracking furnace quenching technology, in order to further shorten the residence time of the adiabatic section of the quench heat exchanger and avoid the problem of uneven distribution of cracked gas, most of the quench heat exchangers for newly built and renovated cracking furnaces use linear quench heat exchangers. The layout of the linear quench heat exchanger heat exchange unit is directly related to the configuration of the radiation furnace tube. Usually, the furnace tube outlet is connected to the quench heat exchanger inlet connector one by one.

[0003] As is known to all, the linear quench heat exchanger is composed of an inlet connection cone, a double-tube heat exchange element, a cooling medium connector, a water vapor header, a high-temperature medium header, a hydraulic coke removal hole, etc. Based on this, the structure of the linear quench heat exchanger is as follows: each double-tube heat exchange element is composed of two concentric tubes, wherein the inner tube carries the high-temperature medium - the cracked gas at about 800°C, and the annular gap between the outer tube and the inner tube carries the cooling medium - a water vapor mixture at about 350°C. Each double-tube heat exchange element is connected to a cracking furnace outlet furnace tube through an inlet connection cone, and multiple double-tube heat exchange elements are arranged in parallel in a single row or double row, and are connected together through a water vapor header and a high-temperature medium header to form a linear quench heat exchanger.

[0029] The connecting mechanism 24 includes a positioning sleeve 26, an upper connecting block 29 and a lower connecting block 28.

By setting a connecting mechanism 24, the plug 37 is driven by the plug rod 31 through the deflection rod 35 to insert into the upper connecting block 29, so that the two connecting blocks complete the plugging of the inner pipe 2 and the access pipe 25. Compared with the existing flange connection, the active plug-in method adopted in this scheme is more convenient in terms of disassembly and assembly, thereby improving the disassembly and assembly efficiency, and further improving the installation and daily maintenance efficiency of the staff.

[0030] Among them, a pulley 6 is fixedly installed on the outer side of the movable ring 4, and a slide rail 5 is fixedly installed on the inner wall of the outer sleeve 1. The other end of the pulley 6 extends to the inside of the slide rail 5 and is slidably connected with the inside of the slide rail 5. The pulley 6 follows the movable ring 4 to slide along the direction of the slide rail 5, thereby improving the movement stability of the movable ring 4.

[0031] Among them, a guide plate 10 is fixedly installed on the inner wall of the outer sleeve 1, a through hole 11 is opened inside the movable ring 4, and the other end of the guide plate 10 extends to the inner side of the movable ring 4 through the through hole 11, and a guide wheel 9 is fixedly installed on the outer side of the clamping plate 8, and the other end of the guide wheel 9 extends to the inside of the guide plate 10 and is slidably connected to the inner wall of the guide plate 10. The guide wheel 9 follows the clamping plate 8 to slide along the direction of the guide plate 10, so that the clamping plate 8 performs a linear motion, and the movement stability of the clamping plate 8 is improved.

[0032] The inner wall of the driving box 13 is rotatably connected with a gear 14, the front of the gear 14 is fixedly connected with a follower rod 15, the inside of the follower rod 15 is slidably connected with a follower wheel 17, the inner wall of the driving box 13 is provided with a slide groove 16, the back side of the follower wheel 17 extends to the inside of the slide groove 16 and is slidably connected with the inner wall of the slide groove 16, the front side of the follower wheel 17 is fixedly connected with the back of the pull rod 12 and extends to one end of the inside of the driving box 13, the inner wall of the driving box 13 is rotatably connected with a toothed plate 19 through a torsion spring 18, the toothed plate 19 is meshed with the gear 14, and the inside of the toothed plate 19 is provided with a The positioning port 20, the inner wall of the driving box 13 is fixedly installed with a positioning rod 21, and the positioning rod 21 is located inside the positioning port 20. The top end of the tooth plate 19 is hinged with a connecting rod 23, and the top end of the connecting rod 23 extends to the outside of the driving box 13 through the connecting seat 22. Because the torsion spring 18 has a certain resilience, the gear 14 in the initial state cannot rotate clockwise. Only by pulling the connecting rod 23 upward can the connecting rod 23 drive the tooth plate 19 to rotate, prompting the gear 14 to move away from the gear 14. At this time, the gear 14 can rotate in the clockwise direction, thereby avoiding the self-rotation of the gear 14.

[0033] Among them, a protective shell 40 is hinged at the connection between the outer sleeve 1 and the drive box 13, and the protective shell 40 is an acrylic protective cover. The drive box 13 is located on the inner side of the protective shell 40. The protective shell 40 can be used to protect the connection between the drive box 13 and the pull rod 12 to avoid the disconnection between the drive box 13 and the pull rod 12 caused by collision with external objects.

[0034] Among them, a second telescopic sleeve 33 is fixedly installed between the cross plate 32 and the bottom of the inner wall of the connecting cavity 30, and springs are arranged on the outer sides of the first telescopic sleeve 7 and the second telescopic sleeve 33. The two sides of the cross plate 32 are slidably connected with the inner wall of the connecting cavity 30 through sliders 34. The second telescopic sleeve 33 can give the cross plate 32 a certain resilience, so that the plug 37 received in the connecting cavity 30 can automatically extend to the outside of the connecting cavity 30, and when the clamping plate 8 overlaps with the inner pipe 2, the first telescopic sleeve 7 is compressed, prompting the first telescopic sleeve 7 to give a certain reaction force to the clamping plate 8.

[0035] The working principle and use process of the present invention are as follows: when in use, the inner tube 2 is first placed inside the outer sleeve, and then the protective shell 40 is rotated to expose the drive box 13. The staff rotates the pull rod 12, so that the pull rod 12 drives the movable ring 4 and the follower wheel 17 to rotate, so that the movable ring 4 drives the clamping plate 8 to slide on the inner side of the guide plate 10 through the telescopic sleeve rod, so that the three clamping plates 8 gradually clamp the surface of the inner tube 2. At the same time, the follower wheel 17 slides inside the slide groove 16, so that the follower rod 15 follows the follower wheel 17 to deflect, so that the follower rod 15 drives the gear 14 to rotate, so that the gear 14 rotates counterclockwise and drives the tooth plate 19 to rotate, and the installation between the outer sleeve 1 and the inner tube 2 is completed;

[0036] When it is necessary to disassemble the outer tube 1 and the inner tube 2, first pull the connecting rod 23 upwards, so that the connecting rod 23 drives the toothed plate 19 to rotate, causing the gear 14 to move away from the gear 14. At this time, the gear 14 can rotate in the clockwise direction. The staff pulls the pull rod 12 again, so that the pull rod 12 drives the movable ring 4 and the follower wheel 17 to rotate clockwise, so that the three clamping plates 8 gradually move away from the inner tube 2, thereby completing the disassembly of the outer tube 1 and the inner tube 2;

[0037] When it is necessary to connect the inner pipe 2 and the access pipe 25, the access pipe 25 is inserted into the inner side of the positioning sleeve 26 so that the inner pipe 2 and the access pipe 25 are overlapped, and then the insertion rod 31 is pulled downward so that the insertion rod 31 drives the deflection rod 35 to deflect at an angle through the cross plate 32, prompting the plug 37 to be retracted into the interior of the connecting cavity 30, and then the positioning sleeve 26 is closed so that the upper connecting block 29 and the lower connecting block 28 are overlapped, and the insertion rod 31 is released. By utilizing the automatic resilience of the spring on the second telescopic sleeve 33, the cross plate 32 drives the plug 37 to extend to the interior of the slot 39, thereby completing the splicing of the inner pipe 2 and the access pipe 25.

[0038] In summary, the linear rapid cooling heat exchanger inlet connector structure, by setting up a disassembly mechanism 3, uses the pull rod 12 to drive the movable ring 4 to rotate, prompting the three clamping plates 8 on the inner side of the movable ring 4 to clamp the inner pipe 2 and cooperate with the gear 14 and the toothed plate 19 to limit the rotation direction of the pull rod 12, avoiding the pull rod 12 from rotating, and the entire installation process does not use bolt and nut connection, so as to achieve the effect of quick disassembly and assembly, thereby avoiding the inconvenience of bolt and nut installation, reducing the disassembly and assembly steps, making the installation of the connector more convenient, and providing many benefits to the installation and daily maintenance of the staff; by setting up a disassembly mechanism 3, using the outer sleeve 1, the inner pipe 2 and the movable ring 4, the outer sleeve 1 and the inner pipe 2 are A buffer cavity is formed between the pipes 2, and its structure can well absorb the expansion thermal stress formed between the outer sleeve 1 and the inner pipe 2 due to the difference in metal wall temperature, and can also effectively reduce the wall thickness of the inner pipe 2, so that the difference in wall thickness between the inner pipe 2 and the outer sleeve 1 is controlled within a certain range, so that the connector has no obvious stress concentration and is conducive to bearing loads; by setting a connecting mechanism 24, the plug 37 is driven by the plug rod 31 through the deflection rod 35 to insert into the upper connecting block 29, so that the two connecting blocks complete the plug-in connection between the inner pipe 2 and the access pipe 25. Compared with the existing flange connection, the active plug-in method adopted in this scheme is more convenient in terms of disassembly and assembly, thereby improving the disassembly and assembly efficiency, and further improving the installation and daily maintenance efficiency of the staff.
