Description

Technical Field

[0001] The utility model relates to the technical field of hydrogenation reaction tubes, in particular to a low-quality raw material hydrogenation reaction tube capable of inhibiting coking. Background Art

[0002] The hydrogenation reactor is a key equipment for hydrogenation reaction in the petrochemical industry. It achieves the modification and conversion of raw materials by chemically reacting the raw materials with hydrogen under high temperature, high pressure and catalyst. Low-quality raw materials usually contain a lot of impurities such as heavy metals, colloids, asphaltene, etc. Hydrogenation of these raw materials can improve the quality of raw materials and increase resource utilization. Hydrogenation of low-quality raw materials and improvement of the coking problem of the hydrogenation reactor can help improve the performance of raw materials and improve product quality.

[0003] However, existing hydrogenation reaction tubes face a serious coking problem when processing inferior raw materials. Due to the complex composition of inferior raw materials, the heavy components and impurities therein are very easy to adhere to and aggregate on the inner wall of the reaction tube under the high temperature and high pressure reaction environment, forming a coking layer. Coking not only reduces the heat transfer efficiency of the reaction tube and increases energy consumption, but also causes the flow channel inside the reaction tube to narrow, affecting the normal flow of materials, and even blocking the reaction tube, reducing the reaction rate. Due to the small space inside the reaction tube, it is impossible to store the driving equipment and cleaning equipment well to clean and remove the coked part. When the coking layer reaches a certain thickness, it may also cause local overheating, accelerate the damage of the reaction tube, shorten its service life, increase equipment maintenance costs and safety risks, and the anti-coking and anti-blocking capabilities are relatively insufficient. To this end, we propose a low-quality raw material hydrogenation reaction tube that can inhibit coking to solve the above problems. Utility Model Content

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] See also Figures 1-6 A hydrogenation reaction tube for low-quality raw materials capable of inhibiting coking comprises a hydrogenation reaction tube body 1, and a limited driving component 2 is correspondingly installed on the outside of the hydrogenation reaction tube body 1;

[0029] The beneficial effects to be expressed by this scheme are as follows: by providing a corresponding limit drive component 2 on the outside of the hydrogenation reaction tube body 1, the limit drive component 2 can stably rotate and operate on the outside of the hydrogenation reaction tube body 1, and a driving rotation component 3 is installed at the bottom of the side of the hydrogenation reaction tube body 1. The driving rotation component 3 can stably drive the limit drive component 2 to rotate on the outside of the hydrogenation reaction tube body 1. The limit drive component 2 always remains stable during the rotation process. The cleaning bracket 4 is rotatably connected to the inside of the hydrogenation reaction tube body 1, and a magnetic drive part 5 is provided on one side of the cleaning bracket 4, and the limit drive component 2 A magnetic follower plate 7 is correspondingly provided on the upper portion. When the limit drive assembly 2 rotates, it drives the magnetic drive member 5, so that the magnetic drive member 5 can magnetically attract the magnetic follower plate 7 to move, thereby driving the overall cleaning bracket 4 to rotate as a whole, so that the cleaning bracket 4 can clean the inner wall of the hydrogenation reaction tube body 1 to prevent adhesion and coking. Moreover, since the driving component is outside the tube body, the occupancy of the interior of the hydrogenation reaction tube body 1 is greatly reduced, which is convenient to use, making the device excellent in decoking and cleaning capabilities, preventing coking and adhesion blockage, and occupying a small internal space, which is convenient to operate and use, thereby improving the durability and service life of the tube body.

[0030] The limit driving component 2 is fixedly installed on the outside of the hydrogenation reaction tube main body 1. The limit driving component 2 is driven by the driving rotation component 3 and rotates on the surface of the hydrogenation reaction tube main body 1. The internal limit of the hydrogenation reaction tube main body 1 is installed with a cleaning bracket 4. When the limit driving component 2 rotates, the magnetic driving part 5 installed on the limit driving component 2 magnetically drives the magnetic follower plate 7. Since the magnetic follower plate 7 is installed on the side of the cleaning bracket 4, it can drive the cleaning bracket 4 at the same time, which makes it convenient for the device to drive the internal components by the external components, and facilitates the cleaning bracket 4 to clean the inside of the hydrogenation reaction tube main body 1, and the operation is stable.

[0031] Furthermore, the position-limiting driving assembly 2 includes a position-limiting carrying ring 21 and a rotating mounting frame 22.

[0038] The outer cleaning brush 43 is mounted on the outer side of the support body 41, and the outer cleaning brush 43 is adapted to rotate on the outer side of the limiting ring 42. The outer cleaning brush 43 is a combination of several sections, and the multi-section limiting position abuts against the upper and lower sides of the limiting ring 42. When the support body 41 rotates, the outer cleaning brush 43 can be driven to clean and scrape off the dirt and coke remaining on the inner wall of the hydrogenation reaction tube body 1, and the dirt remaining on the limiting ring 42 can be scraped off at the same time. At the same time, since the auxiliary cleaning frame 6 remains stationary, the dirt on the surface of the support body 41 can be cleaned in the reverse direction.
