Description

Technical Field

[0001] The present invention relates to the technical field of reaction distillation equipment, in particular to a reaction distillation tower and maintenance equipment thereof. Background Art

[0002] Reactive distillation towers, core equipment in chemical production, integrate chemical reactions and product separation, and are widely used in processes such as esterification, etherification, and alkylation. Their inner walls are exposed to high temperatures, high pressures, and highly corrosive reaction media for extended periods, making them susceptible to both chemical corrosion and physical erosion. To ensure safe and stable operation, these towers are typically coated with a corrosion-resistant protective coating.

[0003] However, during the reactive distillation process, the continuous impact of high-speed liquid flow (especially from the distributor) on the tower walls, as well as the abrasive substances produced by the reaction itself, significantly accelerate the wear and failure of the protective coating. Once the coating is damaged, the corrosive medium will directly attack the tower base material, greatly increasing the risk of equipment perforation and leakage.

[0004] Currently, the cleaning and coating repair and maintenance of the interior walls of reaction distillation towers in the industry generally relies heavily on manual labor. Maintenance personnel typically need to wear heavy protective gear and enter confined spaces through manholes in the tower, or use external platforms to carry out operations with handheld sandblasting, grinding, or spraying equipment. This traditional method is labor-intensive and inefficient. Furthermore, the height (and depth) of reaction distillation towers in modern large-scale chemical plants often reach 8-10 meters or even deeper. When cleaning or repairing deep interior walls near the tower bottom, even with the aid of an extension pole, the reach between the operator's arm and the tool often exceeds 2 meters. In this situation, operators struggle to accurately sense and control the contact force and angle between the tool tip and the tower wall. The excessive lever arm makes the tool tip prone to vibration and deviation, making it difficult to maintain a stable and uniform contact with the complex tower wall curve. This directly leads to incomplete cleaning and uneven and substandard coating application. Summary of the Invention

At the same time, by arranging a middle positioning component 302 in the middle of the connecting column 301, the connecting column 301 is limited during the cleaning and maintenance process, so that the repair component 303 can be in stable fit contact with the tower body 101, ensuring the stable progress of the cleaning and repair operation.

[0038] See also Figure 8 The repair component 303 includes a shell 3031, and an electric push rod 3035 is fixedly installed on the bottom of the inner wall of the shell 3031.

The cleaning roller 3034 is rotatably installed on the inner wall of the roller frame 3033, and the electric push rod 3035 drives the roller frame 3033 to be pushed out, so that the cleaning roller 3034 can be in stable contact with the inner wall of the tower body 101. By changing the pushing pressure of the electric push rod 3035, the contact pressure between the cleaning roller 3034 and the inner wall of the tower body 101 is adjusted, thereby changing the contact effect; a spraying device 3032 is fixedly installed on the bottom of the inner wall of the shell 3031.

The output end of the driving motor 3045 is fixedly connected to the driving roller 3044, and the driving roller 3044 is driven to rotate by the driving motor 3045, thereby driving the cover plate 304 1 and the driving assembly 304 move as a whole along the top edge of the tower body 101, driving the connecting column and the components thereon to move, thereby realizing automated cleaning and maintenance operations of the distillation tower and saving manpower; a lifting motor is fixedly installed on one side of the inner wall of the cover plate 3041, and the output end of the lifting motor is fixedly connected to a lifting guide wheel 3049. A through opening for the connecting column 301 to pass through is opened on the top of the cover plate 3041. After the connecting column 301 passes through the through opening, one side of the lifting guide wheel 3049 is in close contact with the connecting column 301, and the lifting guide wheel 3049 is driven to rotate by the lifting motor, thereby pushing and driving the connecting column 301 to move up and down, thereby realizing the height adjustment of the repair assembly 303, so as to facilitate the cleaning needs of different height positions of the inner wall of the tower body 101.

[0040] In order to improve the stability of the drive assembly 304 during movement, an extension frame 3047 is fixedly connected to the bottom side of the cover plate 3041. The extension frame 3047 is set to an arc shape and its curvature is consistent with the curvature of the outer wall of the tower body 101; the bottom of the extension frame 3047 is fixedly connected to the guide seat plate 3048, and the top of the lower mounting ring 107 is provided with a guide groove 108. The bottom of the guide seat plate 3048 is slidably connected to the inner wall of the guide groove 108 through a slider, and the cooperation between the guide groove 108 and the guide seat plate 3048 is used to limit the bottom of the extension frame 3047, thereby assisting in limiting the entire drive assembly 304.

[0041] See also Figure 9 In order to increase the friction resistance between the connecting column 301 and each component and facilitate the installation and displacement operation of the connecting column 301, a plurality of limit grooves 3014 are opened on the outer wall of the connecting column 301, and a plurality of limit blocks 3024 are fixedly connected to the inner wall of the positioning ring 3023, and the plurality of limit blocks 3024 are respectively slidably connected to the inner walls of the plurality of limit grooves 3014.

[0042] See also Figure 10To meet the needs of cleaning and maintenance of different depths of the inner wall of the tower body 101, the connecting column 301 is divided into several connecting sections 3011, one end of the connecting section 3011 is fixedly connected with a threaded head 3012, and a threaded groove 3013 is provided at one end of the inner wall of the connecting section 3011 away from the threaded head 3012. Two adjacent connecting sections 3011 are threadedly connected to the threaded section through the threaded head 3012, so as to realize flexible adjustment of the overall length of the connecting column 301.

[0043] When the reactive distillation tower 1 of the present invention is in use, the reaction raw materials are introduced through the feed pipe 105. Part of the raw materials are sent to the diversion assembly 2 through the feed pipe 105 for diversion and delivery to participate in the reaction. The materials entering the diversion assembly 2 are sent to the diversion plate 206 through the diversion pipe 205 and then delivered by the side diversion nozzle 208 and the lower diversion nozzle 207. The liquid flow sprayed by the side diversion nozzle 208 and the liquid flow sprayed by the lower diversion nozzle 207 impact each other, so that the liquid flow does not directly impact the inner wall of the tower body 101, thereby slowing down the erosion of the tower body 101.

[0044] After the reaction distillation tower 1 has been in operation for a period of time, maintenance operations are required. Specifically, the locking bolts are manually removed, and the top cover assembly 102 is lifted and removed using an external lifting device. Then, the adjusting bolts are manually rotated to remove the mounting half ring 201 and the entire diverter assembly 2. At this time, the interior of the entire tower body 101 is empty, making maintenance and cleaning operations more convenient.

[0045] Then connect the drive assembly 304 to the tower body 101. Specifically, first connect the docking groove 3042 to the top edge of the tower body 101, and then slide the slider at the bottom of the guide seat plate 3048 to the guide groove 108 at the top of the lower mounting ring 107 to fix the drive assembly 304. Then, pass the connecting column 301 through the opening on the cover plate 3041, pass it through the middle positioning assembly 302, and then fix it to the repair assembly 303 to complete the installation of the maintenance device. For specific status, please refer to Figure 5 and Figure 6 , and then the driving motor 3045 drives the driving roller 3044 to rotate, driving the connecting column 301 and the repair component 303 to contact the inner wall of the tower body 101 as a whole. During this process, the thickness of the tower body 101 is detected by the ultrasonic thickness gauge. When the measured value is greater than the preset wall thickness of the tower body 101, it is determined that impurities are attached here. At this time, the electric push rod 3035 drives the roller frame 3033 to be pushed out, so that the cleaning roller 3034 contacts the inner wall of the tower body 101. The rotation of the cleaning roller 3034 is used to clean the impurities on the inner wall of the tower body 101 until the thickness of the tower body 101 at this location is normal; when the measured value is less than the preset wall thickness of the tower body 101, it is determined that the anti-corrosion coating is eroded here. At this time, the spraying device 3032 is started to re-spray the anti-corrosion coating;

[0046] While the driving component 304 drives the repair component 303 to rotate, the lifting motor drives the lifting guide wheel 3049 to rotate, so as to gradually lower the repair component 303 to meet the cleaning needs of the tower body 101 at different depths; when the middle positioning component 302 moves to the installation slot 109 position, the magnet 3022 and the magnetic ring 110 are attracted to each other, so that the positioning plate 3021 is stuck in the installation slot 109, and then the middle positioning component 302 no longer moves downward with the connecting column 301, but only slides along the installation slot 109, and uses the adsorption force of the magnet 3022 to limit the middle positioning component 302, thereby realizing auxiliary positioning of the connecting column 301; after completing the overall cleaning and maintenance of the interior of the tower body 101, the maintenance equipment 3 is manually removed.

[0047] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
