Description

Technical Field

[0001] This utility model belongs to the technical field of dehydrogenation separation towers, specifically relating to a novel propane dehydrogenation separation tower. Background Technology

[0002] The ADHO alkane dehydrogenation technology primarily consists of a fluidized bed reaction regeneration system and a cryogenic separation system. The reaction regeneration section includes a reaction regeneration system, main air and flue gas energy recovery, a feedstock preheater, a steam generation system, and a fuel supply system. The separation system includes a water washing tower, a gas compressor system, a cold box system, an ethane removal tower, a propane / propylene separation tower, and a feedstock purification system. Both the fluidized bed reaction regeneration system and the cryogenic separation system are mature technologies.

[0003] Currently, existing propane dehydrogenation separation towers typically have auxiliary climbing ladders added to their outer walls to facilitate routine maintenance. These auxiliary climbing ladders are constructed by combining spiral steps with maintenance platforms. However, their coverage area is limited, making it difficult to completely cover the outer wall of the tower. Furthermore, these auxiliary climbing ladders are essentially idle when not being maintained, resulting in very low usage frequency. Therefore, we propose a novel propane dehydrogenation separation tower. Utility Model Content

[0004] The purpose of this invention is to provide a novel propane dehydrogenation separation tower to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel propane dehydrogenation separation tower, comprising a tower body, a lifting ring, and a moving platform. A top plate is fixedly installed on the top of the tower body, and lifting devices are provided at both ends of the top of the top plate. A lifting ring is sleeved on the outside of the tower body, and extension blocks are fixedly installed on the inner walls of both sides of the lifting ring. The lifting devices are fixedly connected to the extension blocks by provided slings. A gear groove is opened on the top surface of the lifting ring, and guide grooves are opened on both sides of the outer side of the gear groove. A moving platform is provided on the top of the lifting ring, and a drive gear is fixedly installed at the center of the bottom of the moving platform. The bottom end of the drive gear extends into the inside of the gear groove and meshes with it. Guide wheels are provided around the bottom of the moving platform, and the guide wheels extend into the inside of the guide groove.

[0006] Preferably, the inner walls on both sides of the guide groove are provided with limiting grooves, and the outer sides of the guide wheel are fixedly provided with limiting posts, which extend into the interior of the limiting groove and are slidably connected to its inner wall.

[0007] Preferably, a drive motor is mounted on the outer side of the drive gear via a mounting base, and the output shaft end of the drive motor is fixedly connected to the drive gear.

[0008] Preferably, guide rods are provided on both sides of the bottom end of the top plate, and the guide rods pass through the extension block and are slidably connected to it.

[0009] Preferably, the bottom of the tower body is provided with a base, and the bottom of the guide rod extends to the top of the base and is fixedly connected thereto.

[0010] Preferably, an electrical control box is provided on one side of the interior of the mobile platform, and a control panel is installed on the top of the electrical control box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By installing a liftable lifting ring on the outside of the tower body and using guide rods for limiting, and then cooperating with a moving platform powered by the meshing of drive gears and gear slots, the platform can move around the lifting ring. This allows the moving platform to reach any position on the outer wall of the tower body during maintenance and repair, greatly increasing the coverage area for maintenance and repair.

[0013] 2. By setting a guide groove at the top of the lifting ring, in conjunction with the guide wheel, a guiding function is provided to prevent the drive gear from derailing. The limit groove and limit post are used to limit the guide wheel, thereby improving the stability of the contact between the guide wheel and the guide groove and preventing the guide wheel from derailing, thus avoiding safety accidents.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a novel propane dehydrogenation separation tower technical solution: including a tower body 1, a lifting ring 6, and a moving platform 11. A top plate 3 is fixedly installed on the top of the tower body 1, and lifting devices 4 are provided at both ends of the top of the top plate 3. The lifting ring 6 is sleeved on the outside of the tower body 1. Extension blocks 10 are fixedly installed on the inner walls of both sides of the lifting ring 6. The lifting devices 4 are fixedly connected to the extension blocks 10 through a sling 5. A gear groove 7 is opened on the top surface of the lifting ring 6, and guide grooves 8 are opened on both sides of the outer side of the gear groove 7. A moving platform 11 is provided on the top of the lifting ring 6. A drive gear 15 is fixedly installed at the center of the bottom of the moving platform 11. The bottom end of the drive gear 15 extends into the inside of the gear groove 7 and meshes with it. Guide wheels 13 are provided around the bottom of the moving platform 11, and the guide wheels 13 extend into the inside of the guide grooves 8.

[0020] Specifically, limit grooves 9 are provided on both inner walls of the guide groove 8, and limit posts 14 are fixedly provided on both outer sides of the guide wheel 13. The limit posts 14 extend into the interior of the limit groove 9 and are slidably connected to its inner wall.

[0021] Specifically, a drive motor 16 is mounted on the outer side of the drive gear 15 via a mounting base, and the output shaft end of the drive motor 16 is fixedly connected to the drive gear 15.

[0022] Specifically, guide rods 17 are provided on both sides of the bottom end of the top plate 3. The guide rods 17 pass through the extension block 10 and are slidably connected to it.

[0023] Specifically, a base 2 is provided at the bottom of the tower body 1, and the bottom of the guide rod 17 extends to the top of the base 2 and is fixedly connected thereto.

[0024] Specifically, an electrical control box 12 is installed on one side of the interior of the mobile platform 11, and a control panel is installed on the top of the electrical control box 12.

[0025] In this implementation scheme, when maintenance and repair of the tower body 1 are required, the staff are placed inside the mobile platform 11 and operate the control panel on the electrical control box 12 to start the lifting device 4 and pull the sling 5, which in turn drives the lifting ring 6 to rise and fall. The guide rod 17 of the device limits the lifting ring 6 to prevent swaying during the ascent. When the lifting ring 6 reaches the appropriate height, the drive motor 16 drives the drive gear 15 to rotate. The meshing connection between the drive gear 15 and the tooth groove in the gear slot 7 drives the mobile platform 11. The mobile platform 11 is moved around the lifting ring 6 to move to a suitable position for specific maintenance and repair of the tower body 1. During this process, the guide wheel 13 moves along the trajectory of the guide groove 8 and is limited by the limit post 14 and the limit groove 9 to prevent the guide wheel 13 from leaving the guide groove 8, causing the mobile platform 11 to derail and thus causing a safety accident. This design allows the mobile platform 11 to reach any position on the outer wall of the tower body 1 during maintenance and repair, greatly improving the coverage area of ​​maintenance and repair.
