Description

Technical Field

[0001] This utility model belongs to the field of bio-kerosene preparation technology, specifically relating to a hydrogenation device for bio-aviation kerosene preparation. Background Technology

[0002] Bio-aviation kerosene is produced using a variety of animal and vegetable oils as raw materials, employing independently developed hydrogenation technology, catalyst systems, and process technologies. The preparation of bio-aviation kerosene requires hydrogenation treatment, which involves mixing and reacting the bio-oil with hydrogen to remove oxygen from the bio-oil. Simultaneously, it converts large hydrocarbon molecules in the bio-oil into smaller hydrocarbon molecules, adjusting the carbon chain length of the bio-kerosene to meet aviation kerosene standards and improve product quality.

[0003] According to the authorization announcement number CN216337450U, a hydrotreating device for base oil production has the advantages of sharing a heating device for hydrogen and base oil, which can reduce equipment failure rate and investment cost; the base oil and hydrogen can undergo a pressurized reaction in the inner cylinder, and the device can also stir the hydrogen and base oil undergoing the pressurized reaction in the inner cylinder, which can ensure that the base oil and hydrogen are fully mixed and react, thus improving production efficiency. However, this device has the following defects in actual application: when hydrogen enters the inner cylinder through the aeration plate, the gas in the inner cylinder... As the pressure gradually increases, the bio-oil will automatically discharge after reaching a certain pressure. There is no sufficient reaction time allowed between the bio-oil and hydrogen. Furthermore, the pressure inside the inner cylinder gradually decreases during discharge, and the pressure outside and inside the inner cylinder tends to balance, preventing the bio-oil from continuing to discharge. If sufficient reaction time is allowed and hydrogen is continuously supplied to the inner cylinder during discharge to maintain the pressure difference between the inside and outside of the inner cylinder, it will lead to a waste of hydrogen resources. Secondly, when heating the bio-oil, relying solely on the heating pipe at the bottom is too slow. Therefore, we propose a hydrogenation device for the preparation of bio-aviation kerosene.

The jet pipe 11 is fixedly connected to the jet valve 24, and one of the hydrogen supply pipes 13 is fixedly connected to the hydrogen supply valve 4. The bio-oil is transported from the feed pipe to the heating chamber 2 and heated by the heating rod 9. The jet valve 24 is opened and the hydrogen supply valve 4 is closed. Hydrogen is transported to the jet plate 10 through the hydrogen supply pipe 13 and then sprayed out, which can tumble the bio-oil. The sprayed hydrogen can enter the reaction chamber 5 from the first return pipe 15 to avoid the waste of hydrogen, thereby achieving the purpose of accelerating the heating of bio-oil.

[0023] Please see Figures 1-5To improve the mixing of hydrogen and bio-oil and accelerate the reaction rate, annular frames 3 are fixedly connected to both sides inside the tank 1. A reaction chamber 5 is rotatably connected to the inner side of the annular frames 3. An annular nozzle 6 is fixedly connected to the top of the inner side of the reaction chamber 5. An oil supply pipe 7 is fixedly installed on one side of the annular nozzle 6. One end of the oil supply pipe 7 is fixedly connected to the bottom of one side of the heating chamber 2, and an air pump 8 is fixedly installed on the oil supply pipe 7. One side of the air pump 8 is fixedly installed on one side of the tank 1. A second reflux pipe 17 is fixedly connected to one side of the four-way pipe 14. One end of the second reflux pipe 17 is fixedly connected to one side of the top of the reaction chamber 5. A reflux pump 18 is fixedly installed on the second reflux pipe 17, and the bottom of the reflux pump 18 is fixedly installed on the top of the reaction chamber 5. A discharge pipe is fixedly connected to the bottom of one side of the reaction chamber 5, and a discharge valve is fixedly installed on the discharge pipe. Convection plates 26 are fixedly installed on both sides inside the reaction chamber 5. A first-order check valve is fixedly connected to the first return pipe 15, and an intake check valve is fixedly installed on the intake pipe 16.

A drive gear 21 is fixedly connected to the output shaft of the motor 20, and a first-order sector gear 25 is fixedly connected to the output shaft of the motor 20. The first-order sector gear 25 is meshed with one side of the rotating gear 19. A driven gear 22 is meshed with one side of wheel 21. A rotating shaft is fixedly sleeved inside the driven gear 22. The rotating shaft is rotatably connected to the top of the baffle, and a second sector gear 23 is fixedly connected to the top of the rotating shaft. The jet valve 24 is closed, and the hydrogen supply valve 4 is opened, allowing hydrogen to enter the interior of the reaction chamber 5 through the hydrogen supply pipe 13 and the air inlet pipe 16. At the same time, the air pump 8 delivers the heated bio-oil through the oil supply pipe 7 to the annular nozzle 6 to spray out, forming an oil mist to increase the contact area with the hydrogen. The motor 20 is started, and the output shaft of the motor 20 rotates, driving the drive gear 21 and the first sector gear 25 to rotate. The drive gear 21 drives the driven gear 22 to rotate in the opposite direction, causing the second sector gear 23 to rotate in the opposite direction. Because the first sector gear 25 and the second sector gear 23 rotate in the opposite direction, the first sector gear 25 and the second sector gear 23 rotate in the opposite direction. The rotation of gear 23 in the opposite direction causes gear 19 to drive reaction chamber 5 to rotate in both directions. The bio-oil in reaction chamber 5 rotates accordingly, forming convection. Under the action of convection plate 26, the collision between bio-oils is further increased, so that the bio-oil comes into more uniform contact with hydrogen. Hydrogen accumulates at the top of the inner cavity of reaction chamber 5. It can be returned to reaction chamber 5 through return pump 18 via return pipe 17 and inlet pipe 16, so that hydrogen can be fully utilized. When the gas pressure in reaction chamber 5 reaches the reaction conditions, hydrogen supply valve 4 is closed. After the bio-oil and hydrogen have fully reacted, the reacted bio-oil is discharged from tank 1 through discharge pipe, thus achieving the purpose of better mixing of hydrogen and bio-oil and accelerating the reaction rate.

[0024] The working principle and usage process of this utility model are as follows: First, the bio-oil is transported from the feed pipe to the heating chamber 2 and heated by the heating rod 9. The jet valve 24 is opened and the hydrogen supply valve 4 is closed. Hydrogen is transported to the jet plate 10 through the hydrogen supply pipe 13 and then sprayed out, which can tumble the bio-oil. The sprayed hydrogen can enter the reaction chamber 5 through the first return pipe 15, avoiding the waste of hydrogen and thus accelerating the heating of the bio-oil. The jet valve 24 is closed and the hydrogen supply valve 4 is opened, allowing hydrogen to enter the interior of the reaction chamber 5 through the hydrogen supply pipe 13 and the air inlet pipe 16. At the same time, the air pump 8 transports the heated bio-oil through the oil supply pipe 7 to the annular nozzle 6 for spraying, forming an oil mist and increasing the contact area with hydrogen. The motor 20 is started, and the output shaft of the motor 20 rotates, driving the drive gear 21 and the first sector gear 25 to rotate. The drive gear 21 drives the... The rotating gear 22 rotates in the opposite direction, causing the second sector gear 23 to rotate in the opposite direction. Due to the opposite rotation of the first sector gear 25 and the second sector gear 23, the rotating gear 19 drives the reaction chamber 5 to rotate in both directions. The bio-oil in the reaction chamber 5 follows the rotation, forming convection. Under the action of the convection plate 26, the collision between the bio-oils is further increased, so that the bio-oil comes into more uniform contact with hydrogen. The hydrogen accumulates at the top of the inner cavity of the reaction chamber 5. The hydrogen at the top can be returned to the reaction chamber 5 through the second return pipe 17 into the air inlet pipe 16 via the return pump 18, so that the hydrogen can be fully utilized. When the gas pressure in the reaction chamber 5 reaches the reaction conditions, the hydrogen supply valve 4 is closed. After the bio-oil and hydrogen have fully reacted, the reacted bio-oil is discharged from the tank 1 through the discharge pipe, thereby achieving the purpose of better mixing of hydrogen and bio-oil and accelerating the reaction rate.
