Description

Technical Field

[0001] This utility model belongs to the field of coal chemical technology, specifically relating to a hydrogenation reaction device in coal chemical industry. Background Technology

[0002] In the coal conversion process, pyrolysis is a key step, and the outcome of the pyrolysis process has a significant impact on the coal conversion process. Coal pyrolysis mainly includes the drying and desorption stage, the decomposition stage of active substances, and the degassing stage. After these stages, coal is converted into coke, tar, and gas to meet different needs. During coal conversion, the coal needs to be pulverized into powder and then fed into the reactor along with hydrogen for the pyrolysis reaction.

[0003] Currently, relatively mature hydrogenation reactor devices exist on the market. For example, a hydrogenation reactor device for coal chemical industry proposed in patent number CN117720939A is described. The powder outlet of the pulverizer is connected to the powder inlet of the filter, and the outlet of the filter is connected to the inlet of the hydrogenation reactor through a mixing pipe. The powder inlet is provided on the side of the filter shell A. A filter element is fixed on the inner side of the shell A. The filter element includes an arc-shaped filter screen A and an arc-shaped filter screen B, with the arc directions of filter screen A and filter screen B being opposite, and filter screen A being located above filter screen B. The powder inlet of the filter is located in the area corresponding to filter screen A, and the concave surface of filter screen A corresponds to the powder inlet. The mixing pipe includes a shell B, on which a coil is installed, and through holes are opened on the coil.

[0004] In the existing coal hydrogenation reactors described above, coal powder tends to adhere to the inner wall of the feed inlet during feeding. During pyrolysis, the residual coal powder easily produces tar, which in turn attracts more coal powder, creating a vicious cycle that can lead to feed inlet blockage and affect processing efficiency, thus presenting certain limitations.

This device, by setting a sliding piston block at the feed port, can remotely and electrically clean the inner wall, effectively preventing tar and other substances from adhering to the inner wall and thus affecting the falling of coal powder. It eliminates the need for manual unblocking, improves processing efficiency, and has significant advantages over traditional hydrogenation reactors.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a hydrogenation reaction device in coal chemical industry, including a reactor 1, a feeding channel 2 fixedly connected to one side of the upper end of the reactor 1, a feeding port 3 fixedly provided on one side of the feeding channel 2, a gas inlet 4 provided at the lower end of the reactor 1, a first power supply 5 fixedly connected to one side of the upper end of the inside of the feeding channel 2, a first drive motor 6 fixedly connected to the other side of the upper end of the inside of the feeding channel 2, a lifting column device 7 fixedly connected to the first drive motor 6, a cleaning piston block 8 fixedly connected to the lower end of the lifting column device 7, and the cleaning piston block 8 slidably disposed inside the feeding channel 2.

[0019] In this embodiment, pulverized coal can be added to the feed channel 2 through the feed port 3. The pulverized coal is fed into the reactor 1 through the feed channel 2, and pyrolyzed using existing technology in conjunction with hydrogen introduced from the gas inlet 4. During the feeding process, when the pulverized coal cokes and adheres to the inner wall of the feed channel 2, the feeding is stopped. Power can be supplied to the first drive motor 6 through the first power supply 5. The start and stop of the first drive motor 6 can be controlled by commonly used remote control. Here, the first drive motor 6 is an intermittently used electronic component with a short operating time, so no diffuser is provided. The heating device, with the first drive motor 6 driving the lifting column device 7 to rise and fall, thereby driving the cleaning piston 8 to rise and fall, can effectively clean the inner wall of the feeding channel 2, effectively preventing tar from adhering to the inner wall and requiring manual cleaning. When cleaning manually, the machine needs to be stopped to ensure safety. After cleaning is completed, the cleaning piston 8 is controlled to rise above the feeding port 3 to continue feeding. This design uses electric control for cleaning, which can remotely control the cleaning and unblocking of the inner wall of the feeding channel 2, effectively avoiding blockages, eliminating the need to stop the machine, and providing good cleaning results, thus improving processing efficiency.

[0020] Specifically, the lifting column device 7 includes a sleeve 9, a sliding column 10, a limiting block 11, and a lead screw 12. The sleeve 9 is fixed inside one side of the feeding channel 2. The sliding column 10 is slidably sleeved in the center of the sleeve 9. The limiting blocks 11 are fixedly connected to both sides of the sliding column 10. Corresponding sliding grooves are provided on the inner wall of the sleeve 9.

[0021] In this embodiment, the sleeve 9 and the sliding post 10 are connected by a limiting sleeve, which limits the sleeve 9 and the sliding post 10 to sliding but not rotating.

[0022] Specifically, one end of the lead screw 12 is fixedly connected to the first drive motor 6, and the other end of the lead screw 12 is threadedly connected to the sliding column 10.

[0023] In this embodiment, after the first drive motor 6 drives the lead screw 12 to rotate, the lead screw 12 can rotate with the sliding column 10. The sliding column 10 is limited to slide only inside the sleeve 9, so that the lead screw 12 can drive the sliding column 10 to rise and fall, thereby driving the cleaning piston 8 to unclog.

[0024] Specifically, a fixing ring 16 is fixedly connected to one side of the surface of the reactor 1, and a support leg 23 is fixedly connected to the lower end of the fixing ring 16.

[0025] In this embodiment, the supporting leg 23 is provided to facilitate the support of the whole.

[0026] Specifically, a drive device 13 is fixedly connected to the upper center of the reactor 1. The drive device 13 is fixedly connected to a rotating shaft 14 via a shaft. One end of the rotating shaft 14 is rotatably set to the opposite side of the reactor 1. A rotating sealing ring 15 is fixedly connected to the lower end of the rotating shaft 14. A gas inlet 4 is fixedly connected to the inner wall of the rotating sealing ring 15.

[0027] In this embodiment, the drive device 13 can drive the rotating shaft 14 to rotate, and the rotating shaft 14 and the gas inlet 4 are connected by a rotating sealing ring 15, so that the rotating shaft 14 can rotate relative to the gas inlet 4.

[0028] Specifically, an air vent 18 is fixedly opened on the surface of the rotating shaft 14, and stirring blades 17 are fixedly connected to both sides of the surface of the rotating shaft 14.

[0029] In this embodiment, after the drive device 13 drives the rotating shaft 14 to rotate, the added raw materials can be stirred by the stirring blade 17. During the stirring process, the introduced hydrogen gas can be quickly and fully mixed with the material by the rotation of the rotating shaft 14, which improves the pyrolysis effect. This design method can improve the efficiency of pyrolysis by introducing gas while stirring the raw materials and making the gas fully mixed with the stirred and dispersed raw materials.

[0030] Specifically, the drive device 13 includes a motor housing 19, a second drive motor 20, and a second power supply 21. Heat dissipation windows 22 are provided on both sides of the motor housing 19. The second drive motor 20 is fixedly connected to one side of the inside of the motor housing 19, and the second power supply 21 is fixedly connected to one side of the inside of the motor housing 19.

[0031] In this embodiment, a second power supply 21 provides power to the second drive motor 20, enabling the second drive motor 20 to rotate. During use, the second drive motor 20 rotates, driving the rotating shaft 14 to rotate. The stirring blades 17 on both sides can stir and disperse the coal powder. During the stirring and dispersing process, gas is introduced through the gas inlet 4, which can fully mix with the dispersed material. To prevent the backflow of coal powder, a slit rubber plug can be used at the gas outlet 18. When gas is introduced, the slit can be opened under pressure, and when the gas is stopped, the slit closes to prevent the backflow of coal powder. The rubber ring is a constant... Due to the limited information available, a detailed description is not provided here. During feeding, when pulverized coal coke adheres to the inner wall of the feeding channel 2, feeding is stopped. Power can be supplied to the first drive motor 6 via the first power source 5. The start and stop of the first drive motor 6 can be controlled via a commonly used remote control system, allowing the first drive motor 6 to drive the lifting column device 7 to rise and fall, thereby driving the cleaning piston 8 to rise and fall. This effectively cleans the inner wall of the feeding channel 2, preventing tar from adhering to the inner wall and requiring manual cleaning. During manual cleaning, the machine must be stopped to ensure safety. After cleaning is completed, the cleaning piston 8 is controlled to rise above the feeding port 3 to continue feeding.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
