Description

Technical Field

[0001] This utility model relates to the field of fixed-bed catalysis technology, and in particular to a fixed-bed catalytic reaction experimental apparatus. Background Technology

[0002] A fixed bed, also known as a packed bed, is a reactor in which reactants are filled or immobilized to achieve the desired reaction. The immobilized material is usually in a honeycomb shape, stacked to a certain height (or thickness) to form a bed layer that remains stationary, through which the catalytic reaction takes place.

[0003] Announcement No. CN217725502U proposes a fixed-bed catalytic reactor. When the motor is started, it drives the rotating shaft to rotate, which in turn drives the stirring rod to rotate. When the stirring rod rotates, it agitates the activated carbon balls in the fixed ring, causing the activated carbon balls to move within the fixed ring. When the waste gas flows upward through the fixed ring, the activated carbon balls come into full contact with the waste gas, thereby improving the denitrification efficiency of the waste gas.

[0004] However, during the implementation of this device, the motor drives the rotating shaft to rotate, which in turn drives the stirring rod to rotate. When the stirring rod rotates, it agitates the activated carbon balls in the fixed ring. Furthermore, the rotating shaft is fixed to the stirring rod. When the activated carbon balls need to be replaced after the reaction is complete, or when the activated carbon balls need to be removed, the rotating shaft needs to be disassembled at the same time to remove them. This makes it inconvenient to remove the mesh frame containing the activated carbon balls. Therefore, a fixed-bed catalytic reaction experimental device is proposed to solve the above problems.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a fixed-bed catalytic reaction experimental device includes a fixed-bed catalytic reaction equipment shell 1, an inlet pipe 2 and an outlet pipe 3 fixedly connected to the surface of the fixed-bed catalytic reaction equipment shell 1, gas entering through the inlet pipe 2 and exiting through the outlet pipe 3, a cover plate 4 provided at the upper end of the fixed-bed catalytic reaction equipment shell 1, a placement frame 6 slidably connected inside the fixed-bed catalytic reaction equipment shell 1, and a first limiting groove 9 opened inside the fixed-bed catalytic reaction equipment shell 1, the inner wall of the first limiting groove 9 being slidably connected to the surface of the placement frame 6, and the first limiting groove 9 being slidably connected to the surface of the placement frame 6. The setting of the tank 9 limits the placement frame 6 and prevents the placement frame 6 from rotating inside the shell 1 of the fixed bed catalytic reaction equipment. The placement frame 6 is rotatably connected to a rotating tube 8, and the interior of the rotating tube 8 is set in a regular hexagon. A stirring rod is set on the surface of the rotating tube 8. The fixed bed catalytic reaction equipment shell 1 is rotatably connected to a rotating shaft 5, and a driving rod 7 is fixedly connected to the surface of the rotating shaft 5. The surface of the driving rod 7 is also set in a regular hexagon. Through the regular hexagonal setting of the driving rod 7 and the rotating tube 8, the driving rod 7 is inserted into the interior of the rotating tube 8, so that when the rotating shaft 5 rotates, it can drive the driving rod 7 and the rotating tube 8 to rotate.

[0026] The rotating tube 8 drives the stirring rod to rotate, which in turn moves the activated carbon balls, allowing for more comprehensive adsorption of the gas. This has been described in the comparative case, so it will not be explained again.

[0027] A motor 14 is fixedly connected to the bottom of the housing 1 of the fixed bed catalytic reaction equipment. The output end of the motor 14 is rotatably connected to the inside of the housing 1 of the fixed bed catalytic reaction equipment, and the output end of the motor 14 is fixedly connected to the rotating shaft 5.

[0028] A filter plate 11 is slidably connected inside the housing 1 of the fixed bed catalytic reaction equipment. The inside of the filter plate 11 is in contact with the surface of the rotating shaft 5. A second limiting groove 10 is provided inside the housing 1 of the fixed bed catalytic reaction equipment. The inner wall of the second limiting groove 10 is slidably connected to the surface of the filter plate 11. The movement of the filter plate 11 is limited by the setting of the second limiting groove 10.

[0029] A rotating frame 12 is fixedly connected to the surface of the rotating shaft 5. A brush 16 is fixedly connected inside the rotating frame 12. The surface of the brush 16 is in contact with the surface of the filter plate 11. A fixed tube 13 is fixedly connected to the bottom of the rotating frame 12. A connecting rod 17 is slidably connected inside the fixed tube 13. A stop block 18 is fixedly connected to one end of the connecting rod 17. A discharge pipe 15 is threadedly connected to the bottom of the shell 1 of the fixed bed catalytic reaction equipment. A push rod 19 is fixedly connected inside the discharge pipe 15. A return spring 20 is movably sleeved on the surface of the connecting rod 17. The two ends of the return spring 20 are fixedly connected to the fixed tube 13 and the connecting rod 17, respectively.

[0030] Working principle: When the placement frame 6 needs to be installed, the operator opens the cover plate 4, then aligns the protrusion on the placement frame 6 with the first limiting groove 9, and at the same time aligns the rotating tube 8 with the drive rod 7. As the placement frame 6 moves down, the drive rod 7 is inserted into the rotating tube 8, thus completing the installation of the placement frame 6. Then the cover plate 4 is closed, and the gas is discharged into the equipment through the inlet pipe 2. At the same time, the motor 14 is started. The output end of the motor 14 drives the rotating shaft 5 to rotate, which in turn drives the drive rod 7 to rotate. The drive rod 7 drives the rotating tube 8 to rotate, causing the stirring rod to move the activated carbon balls.

[0031] At the same time, when the rotating shaft 5 rotates, the rotating shaft 5 drives the rotating frame 12 to rotate, and the rotating frame 12 drives the brush 16 to rotate, so that the rotating frame 12 covers the swept area, preventing the swept impurities from being blown and adsorbed onto the filter plate 11 again by the flowing gas, so that the dust falls into the interior of the fixed tube 13, collects the impurities, and avoids clogging the filter plate 11.

[0032] When it is necessary to collect impurities inside the fixed tube 13, the fixed tube 13 is adjusted to correspond with the discharge tube 15, and then the discharge tube 15 is rotated. The discharge tube 15 moves into the housing 1 of the fixed bed catalytic reaction equipment. The movement of the discharge tube 15 causes the push rod 19 to push the stop block 18, and then the stop block 18 pushes the connecting rod 17 to move, no longer sealing the fixed tube 13, so that the impurities fall into the discharge tube 15 and are discharged.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
