Description

Technical Field

[0001] This utility model relates to the field of chemical products, and in particular to a fluidized bed reactor with an adjustable gas distribution plate angle. Background Technology

[0002] A fluidized bed reactor is a chemical reaction device that uses a fluid (gas or liquid) to suspend solid particulate materials within the device and carry out gas-solid or liquid-solid phase reactions. It is suitable for reaction systems where the substrate is solid particulate material or involves immobilized biocatalysts.

[0003] Chinese Patent CN118022639B discloses a fluidized bed reactor. The gas supply device is connected to the shell, the heat exchanger is installed inside the shell, multiple guide plates are disposed inside the shell and can deflect relative to the shell, adjacent two guide plates are connected by a gear mechanism, the top of the cyclone dust collector is connected to the shell, the bottom of the cyclone dust collector is connected to the bottom of the shell through a return pipe, a filter plate is provided on the return pipe, and an elastically expandable storage box is provided on the outside of the shell. The top of the storage box is connected to the filter plate, and the storage box is connected to one of the guide plates through a transmission component. When fine dust particles filtered by the filter plate are deposited in the storage box, the storage box contracts and drives the guide plate to deflect through the transmission component.

[0004] The fluidized bed reactors described above, when used to process tar and naphthalene oil products, mainly rely on gas distribution plates to distribute gas and suppress polymerization fluidization instability. However, these gas distribution plates are fixedly installed inside the fluidized bed reactor and cannot be adjusted according to the actual reaction conditions. This can easily lead to uneven gas distribution on the distribution plate due to high inlet velocity and high kinetic energy in some raw materials during the reaction, resulting in excessive gas in some areas and insufficient gas in others. Consequently, this affects reaction efficiency and product quality. To address these issues, we propose a fluidized bed reactor with an adjustable gas distribution plate angle. Utility Model Content

[0027] Please see Figures 1 to 6 This utility model provides a technical solution: a fluidized bed reactor with an adjustable gas distribution plate angle, comprising a fluidized bed reactor body 1 and a gas distribution component 2 disposed inside the fluidized bed reactor body 1.

[0028] An assembly 3 is provided between the fluidized bed reactor body 1 and the gas distribution component 2. The assembly 3 is used to assemble the gas distribution component 2.

The half gear 402 and the rack 403 mesh with each other.

[0031] A shaft 401 is rotatably connected to the inner wall of assembly 3. A half gear 402 is fixedly connected to the outer peripheral wall of the shaft 401. A slide rail 404 is fixedly connected to the inner wall of assembly 3. A rack 403 is slidably connected to the bottom of the slide rail 404. The rack 403 is used to rotate the half gear 402. An electric telescopic rod 405 is fixedly connected to the end of the rack 403. The electric telescopic rod 405 is fixedly installed on the inner wall of assembly 3. The electric telescopic rod 405 can drive the rack 403 to move left and right. At the same time, the rack 403 can drive the half gear 402 to rotate. At this time, the half gear 402 can drive the shaft 401 and the gas distributor 2 to rotate, which facilitates the adjustment of the angle of the gas distributor 2 and improves the uniformity of airflow distribution in the bed.

[0032] The top of the assembly 3 is provided with a connecting component 5 for fixing it. The connecting component 5 includes a connecting rod 501, which is fixedly connected to the top of the fluidized bed reactor body 1. The top of the assembly 3 has multiple sets of connecting holes 302, and the connecting rod 501 is inserted into the inside of the connecting holes 302.

[0033] The connecting component 5 also includes an arc-shaped rod 502, which is well connected inside the assembly 3. The arc-shaped rod 502 passes through the side wall of the connecting rod 501. A pressing member 504 passes through the top of the assembly 3. A wedge member 503 is fixedly connected to the bottom of the pressing member 504. The wedge member 503 slides up and down inside the assembly 3. The wedge member 503 and the arc-shaped rod 502 are slidably connected. By pressing the pressing member 504 downward, the wedge member 503 can be moved downward, and the two sets of arc-shaped rods 502 can be moved towards each other.

When the pressing member 504 is released, the tension of the spring 505 can reset the pressing member 504 and the wedge member 503 upwards. At the same time, the wedge member 503 will squeeze the two sets of arc-shaped rods 502 and penetrate the connecting rod 501, thus installing the accessory 3 inside the fluidized bed reactor body 1. Next, the fluidized bed reactor body 1 is driven to work, and the rack 403 is driven to move left and right by the electric telescopic rod 405. At the same time, the rack 403 can drive the half gear 402 to rotate. At this time, the half gear 402 can drive the shaft 401 and the gas distributor 2 to rotate, which can adjust the angle of the gas distributor 2 and distribute the airflow evenly.
