Description

Technical Field

[0001] The utility model relates to the field of chemical processing, in particular to an exhaust system of a liquid phase hydrogenation reactor. Background Art

[0002] The liquid phase hydrogenation reactor is a device used in the chemical process to remove impurities such as unsaturated hydrocarbons and sulfur from petroleum products. During the hydrogenation process, hydrogen reacts with crude oil under the action of a catalyst to produce products such as saturated hydrocarbons and hydrogen sulfide. In order to improve the reaction efficiency, it is necessary to continuously discharge the gas containing by-products. The liquid phase hydrogenation reactor is generally placed in an open-air environment. When the weather is bad, the dust and other floating objects in the air will fall to the top of the liquid phase hydrogenation reactor, and it needs to be cleaned manually on a regular basis. Otherwise, once the dust and other garbage accumulate, the service life of the liquid phase hydrogenation reactor will be reduced, and the use of manual cleaning will lead to an increase in cleaning costs and manual work intensity. For this reason, we propose an exhaust system for a liquid phase hydrogenation reactor. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 , an exhaust system for a liquid phase hydrogenation reactor, comprising a liquid phase hydrogenation reactor 1, an outer wall of the liquid phase hydrogenation reactor 1 is provided with a surrounding protective sleeve 2 near the top, a driving motor 3 is fixedly provided at the top center of the liquid phase hydrogenation reactor 1, an output shaft of the driving motor 3 is rotatably connected to a rotating disc 14, and further comprising:

[0026] The top garbage removal assembly is installed at the bottom of the rotating disc 14 and is used to scrape the top garbage of the liquid phase hydrogenation reactor 1.

[0027] The side garbage scraping assembly is installed on the side of the rotating disc 14 and is used to scrape the side garbage of the liquid phase hydrogenation reactor 1.

[0028] The top of the liquid phase hydrogenation reactor 1 near the edge is sloped, and the dust and other garbage are thrown to the bottom inner wall surrounding the protective cover 2 for collection through the rapid rotation of the scraper bar 11. At the same time, the scraper 8 connected to the side plate 7 scrapes the garbage at the sloped position on the top of the liquid phase hydrogenation reactor 1.

[0029] Two sets of symmetrical drainage pipes 4 are fixedly provided at the bottom of the surrounding protective cover 2, and water storage tanks 5 are fixedly provided directly below the two sets of drainage pipes 4 on both sides of the liquid phase hydrogenation reactor 1. The garbage thrown into the inner wall of the bottom of the surrounding protective cover 2 flows into the water storage tank 5 through the two sets of drainage pipes 4 for collection.

[0030] A water spray pipe 12 for softening dust is fixedly arranged on the outer wall of the rotating disc 14, and a plurality of water spray heads 13 arranged equidistantly are fixedly arranged at the bottom of the water spray pipe 12. When the top of the liquid phase hydrogenation reactor 1 and the sloped position on the liquid phase hydrogenation reactor 1 need to be cleaned, water is injected into the water spray pipe 12 through the water spray head 13 to spray water downward.

[0031] The top garbage removal component includes a vertical plate 10 and a scraper 11. A vertical plate 10 is fixedly provided at the bottom of the rotating disc 14. The bottom end of the vertical plate 10 is fixedly provided with an integrated scraper 11 which is perpendicular to the vertical plate 10. The bottom of the scraper 11 is completely in contact with the top of the liquid phase hydrogenation reactor 1. After softening the dust on the top of the liquid phase hydrogenation reactor 1, the drive motor 3 is started, and the rotating disc 14 is driven to rotate by the output shaft of the drive motor 3. The scraper 11 on the vertical plate 10 performs a circular rotation motion on the top of the liquid phase hydrogenation reactor 1 when the rotating disc 14 rotates.

[0032] The side garbage scraping assembly includes a side plate 7, a scraper 8 and a stabilizing ring strip 9. A horizontal side plate 7 is fixedly provided on the side of the rotating disc 14 in the opposite direction of the vertical plate 10. An integrated scraper 8 extending downward is fixedly provided at the end of the side plate 7 away from the rotating disc 14.

A horizontal stabilizing ring strip 9 is fixedly provided at the middle position of the side of the scraper 8 away from the liquid phase hydrogenation reactor 1. The scraper strip 11 fits with the top of the liquid phase hydrogenation reactor 1 and scrapes away the dust and other garbage on the top of the liquid phase hydrogenation reactor 1.

[0033] One end of the stabilizing ring strip 9 facing away from the scraper 8 is slidably connected in the annular groove 6. The stabilizing ring strip 9 slides in the annular groove 6 following the sliding of the scraper 8, thereby ensuring the stability of the scraper 8 when sliding.

[0034] Working principle: When the top of the liquid phase hydrogenation reactor 1 and the sloped position on the liquid phase hydrogenation reactor 1 need to be cleaned, water is injected into the water spray pipe 12 through the water spray head 13 to spray water downwards, and the dust on the top of the liquid phase hydrogenation reactor 1 is softened. Then the drive motor 3 is started, and the output shaft on the drive motor 3 drives the rotating disc 14 to rotate. The scraper 11 on the vertical plate 10 rotates in a circle on the top of the liquid phase hydrogenation reactor 1 when the rotating disc 14 rotates. The scraper 11 is connected to the liquid phase hydrogenation reactor 1. The top of the reactor 1 is attached to and scrapes off the dust and other garbage on the top of the liquid phase hydrogenation reactor 1. The dust and other garbage are thrown to the bottom inner wall of the surrounding protective sleeve 2 for collection through the rapid rotation of the scraper bar 11. At the same time, the scraper 8 connected to the side plate 7 scrapes off the garbage at the sloped position on the top of the liquid phase hydrogenation reactor 1. The stabilizing ring bar 9 follows the sliding of the scraper 8 and slides in the ring groove 6 to ensure the stability of the scraper 8 when sliding. The garbage thrown into the bottom inner wall of the surrounding protective sleeve 2 flows into the water tank 5 through two sets of drainage pipes 4 for collection.
