Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bio-kerosene technology, specifically relating to a hydrocracking reactor for preparing bio-aviation kerosene. Background Technology
[0002] Bio-aviation kerosene is produced using various animal and vegetable oils as raw materials, employing independently developed hydrogenation technology, catalyst systems, and process technologies. Bio-aviation kerosene does not require modifications to aircraft or engines. If it can achieve large-scale commercialization and meet aviation airworthiness certification standards in the future, aviation biofuels will effectively solve environmental and energy problems in the civil aviation industry. In the production process of bio-aviation kerosene, hydrogenation mainly involves hydrorefining and hydrocracking. The main purpose of hydrocracking is to convert heavy oils into light oils, such as gasoline, kerosene, diesel, or feedstocks for catalytic cracking and pyrolysis to produce olefins. Through the hydrocracking reaction, the relative molecular mass and carbon-hydrogen ratio of the oil are changed. Various solid catalysts, such as Raney nickel, palladium, and nickel, are required during the hydrocracking process.
[0003] According to the patented technology of a petroleum hydrocracking device with authorization announcement number CN214457789U, although the device has advantages such as the use of a vibrating screen, a vibrating screen motor, and a vibrating screen mechanism to screen the catalyst during the catalyst addition process to prevent catalyst agglomeration and uneven addition affecting the effect, and the use of a sealed feeding mechanism, a threaded pipe, and a feeding pipe to ensure that the catalyst has minimal contact with the outside air during feeding, thus greatly reducing the impact of the external environment on the catalyst, this patented technology has the following defects in practical application: Since the catalyst is supported by the tension of a spring, and the agglomerated catalyst is removed by vibration, when a large amount of catalyst enters the device, the spring may break under the load of high-frequency vibration, causing damage to people or property and posing a safety risk. Furthermore, since the catalyst is solid, the vibrated catalyst is prone to blockage when discharging, affecting the normal addition of catalyst. Therefore, we propose a hydrocracking reactor for the preparation of bio-aviation kerosene. Utility Model Content

[0021] The present invention will be further described below with reference to the embodiments.
[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0023] Please see Figures 1-6This invention provides a hydrocracking reactor for producing bio-aviation kerosene, comprising a tank 1. To de-clump the catalyst, an inverted Y-shaped cover 2 is fixedly connected to the top of the inner side of the tank 1, penetrating the tank 1. Four electric actuators 3 are fixedly connected to the top of the tank 1, and crossbars 4 are fixedly connected to the bottom of the four electric actuators 3. Four support rods 5 are fixedly connected to the top of the crossbars 4, and a vibrating chamber 6 is slidably connected to the top of the four support rods 5. A de-clumping motor 7 is fixedly connected to the top of the crossbars 4, and a de-clumping gear 8 is fixedly connected to the output shaft of the de-clumping motor 7. A rotating gear 9 is meshed with one side of the de-clumping gear 8. A short sleeve 10 is fixedly connected to the inner side of the rotating gear 9, and the top of the short sleeve 10 is fixedly connected to the bottom of the vibrating chamber 6. A vibrating gear 11 is fixedly connected to the output shaft of the de-clumping motor 7, and a small gear 12 is meshed with one side of the vibrating gear 11. A long sleeve 13 is fixedly connected to the top of the small gear 12, and the top of the long sleeve 13 is fixedly connected to... An eccentric wheel 14 is slidably connected to a short rod on its outer side. An impact rod 15 is rotatably connected to one side of the short rod. A slider 16 is slidably connected to the outside of the impact rod 15. A connecting rod is rotatably connected to one side of the slider 16. A central rod 17 is fixedly connected to one side of the connecting rod. The bottom of the central rod 17 is fixedly connected to the top of the cross 4. When the de-caking motor 7 is started, the catalyst is added from the top of the inverted Y-shaped cover 2 into the interior of the inverted Y-shaped cover 2. The output shaft of the de-caking motor 7 drives the de-caking gear 8 to rotate, which in turn drives the rotating gear 9 to rotate, thereby driving the short sleeve 10 and the vibrating chamber 6 to rotate. The agglomerated catalyst is squeezed between the inverted Y-shaped cover 2 and the vibrating chamber 6. At the same time, the output shaft of the de-caking motor 7 drives the vibrating gear 11 to mesh with the pinion 12 to rotate, thereby driving the long sleeve 13 and the eccentric wheel 14 to rotate. The rotation of the eccentric wheel 14 will drive the short rod and the impact rod 15 to move continuously, so that the impact rod 15 impacts the inner wall of the vibrating chamber 6, producing a vibration effect, thereby achieving the purpose of de-caking the agglomerated catalyst.
[0024] Please see Figure 1 and Figure 4To prevent material blockage during the feeding process, a baffle 23 is fixedly connected to the bottom of the inner side of the tank body 1. A funnel 18 is fixedly connected inside the tank body 1. A first feeding pipe 19 is fixedly connected to the bottom of the funnel 18. A discharge gear 20 is rotatably connected to the bottom of the first feeding pipe 19. A straight rod is fixedly connected to both sides inside the discharge gear 20. A first stirring rod 21 is fixedly connected to both sides of the top of the straight rod, and a second stirring rod is fixedly connected to the bottom of the straight rod. A second feeding pipe 22 is rotatably connected to the bottom of the discharge gear 20. The external fixed connection of 22 is to the inside of the baffle 23. A stirring motor 24 is fixedly connected to one side of the top of the baffle 23. A stirring gear 25 is fixedly connected to the output shaft of the stirring motor 24. The stirring gear 25 is meshed with one side of the discharge gear 20. The output shaft of the stirring motor 24 drives the stirring gear 25 to rotate, thereby driving the discharge gear 20 to rotate, which in turn drives the first rod, the first stirring rod 21 and the second stirring rod to rotate, so that the first stirring rod 21 and the second stirring rod can stir the catalyst to prevent material blockage during the feeding process.
[0025] Please see Figure 1 and Figure 5 To ensure quantitative catalyst discharge, a discharge hopper 26 is fixedly connected to the bottom of the baffle 23, and a discharge motor 27 is fixedly connected to the bottom of the inner side of the tank 1. The output shaft of the discharge motor 27 is fixedly connected to a discharge turntable 28. The bottom of the discharge hopper 26 penetrates the bottom of the tank 1, and the discharge turntable 28 is located inside the discharge hopper 26 and fits against the discharge hopper 26. Four discharge slots are opened inside the discharge turntable 28. The output shaft of the discharge motor 27 drives the discharge turntable 28 to rotate. When the discharge slot is at the bottom of the second discharge pipe 22, the catalyst falls into the discharge slot. The discharge turntable 28 continues to rotate, which can discharge the catalyst in the discharge slot through the bottom of the discharge hopper 26, thereby achieving the purpose of quantitative catalyst discharge.
[0026] The working principle and usage process of this utility model are as follows: First, the de-caking motor 7 is started, and the catalyst is added from the top of the inverted Y-shaped cover 2 into the interior of the inverted Y-shaped cover 2. The output shaft of the de-caking motor 7 drives the de-caking gear 8 to rotate, which in turn drives the rotating gear 9 to rotate, thereby driving the short sleeve 10 and the vibrating chamber 6 to rotate. The agglomerated catalyst is squeezed between the inverted Y-shaped cover 2 and the vibrating chamber 6. At the same time, the output shaft of the de-caking motor 7 drives the vibrating gear 11 to mesh with the small gear 12 to rotate, thereby driving the long sleeve 13 and the eccentric wheel 14 to rotate. The rotation of the eccentric wheel 14 will drive the short rod and the impact rod 15 to move continuously, so that the impact rod 15 impacts the inner wall of the vibrating chamber 6, producing a vibration effect. The catalyst agglomeration is thus removed. The output shaft of the stirring motor 24 drives the stirring gear 25 to rotate, which in turn drives the discharge gear 20 to rotate, thereby driving the first stirring rod, the first stirring rod 21, and the second stirring rod to rotate. This allows the first stirring rod 21 and the second stirring rod to stir the catalyst, preventing material blockage during the feeding process. The output shaft of the discharge motor 27 drives the discharge turntable 28 to rotate. When the discharge trough is at the bottom of the second discharge pipe 22, the catalyst falls into the discharge trough. The discharge turntable 28 continues to rotate, discharging the catalyst from the discharge trough through the bottom of the discharge bin 26, thus achieving the purpose of quantitative catalyst discharge.
