Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary installation equipment, in particular to a rotating device for assisting in the high-altitude installation of a reactor. Background Art

[0002] The propane dehydrogenation reactor is the core equipment in the propane dehydrogenation unit PDH. Due to the special structure, large size and heavy weight of the reactor equipment, and it has large nozzles in the shape of a "cactus", normal installation after rotation cannot be completed on the ground. Traditional installation usually involves rotation in the air after hoisting, and alignment, welding, non-destructive testing, pressure testing and paint repair are carried out in the high-altitude environment. However, during the hoisting process of the propane dehydrogenation reactor, the problem of sling displacement is extremely likely to occur, resulting in great construction difficulty and high risk of high-altitude operation.

[0003] In order to solve the problem that the sling is extremely likely to shift during the hoisting of the propane dehydrogenation reactor, the Chinese utility model patent with the patent number CN216458663U discloses a high-efficiency dehydrogenation reactor for a propane dehydrogenation unit, including a reaction tank. Four reinforcing rings are symmetrically installed on the outer wall of the reaction tank, and a reinforcing rib is fixedly connected to the center of the bottom of the reaction tank. Bottom plates are respectively installed on both sides of the bottom of the reaction tank, and a hydrocarbon outlet pipe and an air outlet pipe are respectively fixedly connected to the bottoms of the bottom plates. A vacuum extraction pipe is fixedly connected to one side of the air outlet pipe. Both the hydrocarbon outlet pipe and the air outlet pipe are communicated with the inside of the reaction tank. Hoisting mechanisms are symmetrically installed on both sides of the center of the bottom of the reaction tank.

[0004] There are at least the following problems in the prior art: The reactor still rotates in the air, and all manufacturing processes cannot be completed on the ground at one time. Large nozzles such as "cactus" still need to be aligned, welded, non-destructively tested, pressure tested and painted in the high-altitude environment. The construction difficulty and the risk of high-altitude operation have not been effectively improved, and the economy in terms of human resources, equipment investment, construction period, etc. is quite considerable.

[0036] As Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7 shown, a number of groups of mounting holes are provided on the top of the base 2. The base 2 includes a bottom plate 21, a top plate 22, a web 23 and a rib plate 24. The bottom plate 21 is arranged on the steel beam 18 of the top beam 11. The top plate 22 is arranged on the bottom plate 21 through two webs 23. The rib plate 24 is arranged between the two webs 23. The mounting holes are arranged at the edge of the top plate 22 outside the two webs 23. By providing the mounting holes, it is convenient to adjust the position of the support 3 according to the diameter of the propane dehydrogenation reactor 7, so that the support 3 and the roller support 4 can stably support the propane dehydrogenation reactor 7 for rotation; by providing the bottom plate 21, the top plate 22, the web 23 and the rib plate 24, a box-shaped structure can be prefabricated, and the support capacity is strong.

[0037] As Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, the bottom of the support 3 is connected to the mounting holes on the base 2 through fixing bolts, which facilitates disassembly, position adjustment, and installation and fixing; the support 3 includes a bottom connecting plate 31, a top support plate 32, vertical plates 33, vertical rib plates 34, and a cover plate 35. The bottom connecting plate 31 is connected to the top plate 22 of the base 2. The top support plate 32 is arranged on the bottom connecting plate 31 through two groups of vertical plates 33.

A support pad 5 is provided on the top of the support 3. By providing the support pad 5, the roller support 4 can be supported.

[0038] As Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 shown, the roller support 4 includes rollers 41, a support 42, a speed reducer 43, and a motor 44. The rollers 41 are arranged between two groups of supports 42 through roller shafts and bearings. The support 42 and the motor 44 are both arranged on the support pad 5. The speed reducer 43 is arranged on the top support plate 32. The output end of the motor 44 is connected to the input end of the speed reducer 43 through a coupling. The output end of the speed reducer 43 is connected to the roller shaft through a coupling. By providing the rollers 41, the propylene dehydrogenation reactor 7 can be supported and driven to rotate; by providing the support 42, the rotation of the rollers can be supported; by providing the speed reducer 43 and the motor 44, the rollers 41 can be actively driven to rotate, thereby driving the propylene dehydrogenation reactor 7 to rotate.

[0039] Before use, after the ground load test on the foundation is qualified by the staff, the roadbed plate 6 is placed on the foundation to ensure that the flatness of the upper surface of the roadbed plate 6 does not exceed 2 mm; then the columns 15, the second cross beam 16, and the second diagonal brace 17 are assembled, spot-welded, and reinforced to form three groups of support frames 12. The three groups of support frames 12 are taken to the platform for lofting, and then the three groups of support frames 12 are vertically assembled, spot-welded, and reinforced with the first cross beam 13 and the first diagonal brace 14 according to the lofting dimensions; before the steel beam 18 and the connecting beam 19 are assembled, spot-welded, and reinforced to form the top beam 11, leveling is required, and the flatness of the upper surface is controlled within 0.5 mm. After the top beam 11 is made, the upper surface is machined and leveled, and then placed on the three groups of support frames 12 for overall welding; all components are assembled without gaps to avoid welding deformation during the welding process;

[0040] Then the staff assembles and welds the bottom plate 21, the top plate 22, the web plate 23, and the rib plate 24 on the top beam 11 to form the base 2, and assembles and welds the bottom connecting plate 31, the top support plate 32, the vertical plates 33, the vertical rib plates 34, and the cover plate 35 on the top beam 11 to form the support 3. The upper and lower surfaces of the base 2 and the support 3 are machined, and the height and parallelism are required to be controlled within the range of 0.05 mm, and drilling is carried out, and then they are assembled and fastened with bolts;

[0041] Then, the staff assembles the roller 41, the bracket 42, the speed reducer 43 and the motor 44 into the roller bracket 4. The roller 41 is integrally machined from round steel, assembled with an interference fit with the roller shaft and welded. Both ends of the roller shaft are connected to the bracket 42 through bearings. During the entire assembly process, all components are in a free state to eliminate transmission clearance, and all fasteners are tightened.

[0042] Finally, the power distribution cabinet 8 is connected to the motor 44 through a cable. Electrical components such as inverters, relays, circuit boards, and infrared receivers are installed inside the power distribution cabinet 8. After installation, it is debugged using a remote control. After the debugging is completed, it is then subjected to test runs. After passing the tests, it is put into use.

[0043] As Figure 8 shown, when the propane dehydrogenation reactor 7 is transported to near the roadbed plate 6 by an axis vehicle, a 650-ton crawler crane is used to lift and place the product onto the roller bracket 4 through a lifting lug. After removing the lower lifting rope, by operating the remote control, the motor 44 drives the roller 41 to rotate the propane dehydrogenation reactor 7. As Figure 9 shown, when the large nozzle "cactus" rotates to the top, it stops; then the originally removed lifting rope is installed on the lifting lug on the other side. After the installation is completed, a trial lift is carried out. After the trial lift is correct, it is officially lifted to the designated foundation position to complete the single-unit operation; repeat the above operation until the installation of 8 reactors is completed. By optimizing the lifting method, one set of the lifting lugs in the primary lift is cleverly shared in the secondary lift, and one set of welding of the lifting lugs can be reduced for each device; the utility model realizes the unobstructed high-altitude rotation of the reactor, meets the construction needs of this project. At the same time, large nozzles such as "cactus" are manufactured as a whole on the ground, greatly reducing the construction cost and the input of human resources, reducing the work intensity and the risk of unsafe factors. The utility model occupies a relatively small area, is simple to operate, convenient to disassemble and assemble, and easy to transport.
