Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and specifically discloses a gas distribution mechanism for a reaction vessel. Background Technology

[0002] In gas-liquid or gas-solid phase reaction processes in fields such as chemical engineering, environmental protection, and bio-fermentation, it is usually necessary to introduce gas into the reactor to participate in the reaction. The uniformity of gas distribution is one of the key factors determining reaction efficiency, product quality, and energy consumption. Therefore, a gas distribution mechanism is typically installed inside the reactor.

[0003] Existing gas distribution mechanisms are mostly static or simple dynamic in form. Static gas distributors, such as porous coils and ring distributors, have simple structures but fixed gas distribution ranges, which can easily create dead zones in the gas distribution within the reactor, leading to problems such as uneven reaction, local overheating, or increased byproducts. Furthermore, static gas distribution mechanisms can easily cause material to adhere to the pores, posing a risk of pore blockage. Therefore, a new gas distribution mechanism for reactors is needed to solve this problem. Utility Model Content

[0004] This invention proposes a gas distribution mechanism for a reaction vessel. By making the gas nozzles perform three-dimensional compound motion, the uniformity of gas distribution and reaction efficiency are significantly improved. At the same time, its dynamic operation mode can effectively prevent gas nozzle blockage and enhance the stability and applicability of the system.

[0005] This utility model is implemented as follows: a gas distribution mechanism for a reaction vessel includes a reaction vessel body. A gas distribution mechanism is provided inside the reaction vessel body. The gas distribution mechanism includes a main pipe that penetrates and is rotatably connected inside the reaction vessel body. The upper end of the main pipe extends to the outside of the reaction vessel body and is rotatably connected to an inlet pipe via a rotating joint. A shell is fixedly connected to the outer wall of the main pipe. A horizontal pipe located inside the shell is connected to the lower end of the main pipe. Both ends of the horizontal pipe are rotatably connected to branch pipes rotatably connected to the shell via rotating joints. Multiple gas distribution pipes are connected to the outer walls of both branch pipes. Several evenly distributed gas nozzles are provided on the outer walls of the multiple gas distribution pipes. A connecting shaft extending into the shell and rotatably connected to the lower end face inside the reaction vessel body is fixedly connected. A first bevel gear located inside the shell is fixedly connected to the outer wall of the connecting shaft. Second bevel gears meshing with the first bevel gear are fixedly connected to the outer walls of both branch pipes.

[0006] As a preferred embodiment of the gas distribution mechanism for the reactor of this utility model, a drive motor is installed on the upper end face of the reactor body, a first synchronous pulley is fixedly connected to the output end of the drive motor, a second synchronous pulley is fixedly connected to the outer wall of the main pipe, and the first synchronous pulley and the second synchronous pulley are connected by a synchronous belt drive.

[0007] As a preferred embodiment of the gas distribution mechanism for a reaction vessel according to this utility model, a first mechanical seal is provided between the main pipeline and the reaction vessel body.

[0008] As a preferred embodiment of the gas distribution mechanism for the reactor of this utility model, a second mechanical seal is provided between each of the two branch pipes and the shell.

[0009] As a preferred embodiment of the gas distribution mechanism for a reaction vessel according to this utility model, a third mechanical seal is provided between the connecting shaft and the shell.

[0010] As a preferred embodiment of the gas distribution mechanism for a reaction vessel according to this utility model, a controller is provided on the outer wall of the reaction vessel body, and the drive motor is electrically connected to the controller.

[0011] The beneficial effects of this utility model are: 1. Through a bevel gear transmission mechanism, the gas distribution pipe rotates horizontally and vertically simultaneously, driving the gas nozzle to perform a three-dimensional composite motion. This greatly expands the gas injection coverage area, effectively eliminates dead zones in gas distribution within the reactor, and thus significantly improves the uniformity and efficiency of gas-liquid or gas-solid two-phase reactions.

[0012] 2. The complex three-dimensional movement of the gas distribution pipe and the gas nozzle continuously disturbs the fluid inside the reactor. This dynamic environment makes it difficult for solid particles or crystals to adhere and deposit on the surface of the gas nozzle. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0020] Please see Figure 1-4 A gas distribution mechanism for a reaction vessel includes a reaction vessel body 1. A gas distribution mechanism is installed inside the reaction vessel body 1. The gas distribution mechanism includes a main pipe 2 that penetrates and is rotatably connected inside the reaction vessel body 1. The upper end of the main pipe 2 extends to the outside of the reaction vessel body 1 and is rotatably connected to an inlet pipe 3 via a rotary joint. A housing 7 is fixedly connected to the outer wall of the main pipe 2. A horizontal pipe 8 located inside the housing 7 is connected to the lower end of the main pipe 2. Both ends of the horizontal pipe 8 are rotatably connected to branch pipes 9 rotatably connected to the housing 7 via rotary joints. Multiple gas distribution pipes 10 are connected to the outer walls of both branch pipes 9. Several evenly distributed gas nozzles 11 are provided on the outer walls of the multiple gas distribution pipes 10. A connecting shaft 12 extending into and rotatably connected to the housing 7 is fixedly connected to the lower end face inside the reaction vessel body 1. A first bevel gear 13 located inside the housing 7 is fixedly connected to the outer wall of the connecting shaft 12. Second bevel gears 14 meshing with the first bevel gear 13 are fixedly connected to the outer walls of both branch pipes 9.

[0021] In this embodiment: rotating the main pipe 2 causes the shell 7 to rotate, which in turn causes the two branch pipes 9 to rotate in the horizontal direction. When the branch pipes 9 rotate in the horizontal direction, they further cause the second bevel gear 14 to roll along the first bevel gear 13, which in turn causes the branch pipes 9 to rotate in the vertical direction while revolving in the horizontal direction. The branch pipes 9 further cause multiple gas distribution pipes 10 to rotate in the vertical direction while revolving in the horizontal direction, which in turn causes several gas nozzles 11 to perform three-dimensional compound motion, so that the gas is evenly introduced into the reactor body 1.

[0022] It should be noted that the rotary joint is a component with a mechanical seal structure. Its fundamental function is to ensure that the required relative movement can occur between the fixed pipe and the rotating component and to achieve a reliable seal while gas is introduced. This is existing technology, and its structure will not be described in detail here.

[0023] As a technical optimization of this utility model, a drive motor 4 is installed on the upper end face of the reactor body 1, and a first synchronous pulley 5 is fixedly connected to the output end of the drive motor 4. A second synchronous pulley 6 is fixedly connected to the outer wall of the main pipe 2, and the first synchronous pulley 5 and the second synchronous pulley 6 are connected by synchronous belt transmission.

[0024] In this embodiment: the drive motor 4 is started, the drive motor 4 drives the first synchronous pulley 5 to rotate, and then drives the second synchronous pulley 6 to rotate through the synchronous belt, which in turn drives the main pipeline 2 to rotate, thereby driving the air distribution mechanism to rotate.

[0025] As a technical optimization of this utility model, a first mechanical seal is provided between the main pipeline 2 and the reactor body 1.

[0026] In this embodiment: by setting a first mechanical seal between the main pipe 2 and the reactor body 1, it is easy to maintain a good seal between the main pipe 2 and the reactor body 1.

[0027] As a technical optimization of this utility model, a second mechanical seal is provided between each of the two branch pipes 9 and the housing 7.

[0028] In this embodiment, by providing a second mechanical seal between both branch pipes 9 and the housing 7, it is easy to maintain a good seal between the branch pipes 9 and the housing 7.

[0029] As a technical optimization of this utility model, a third mechanical seal is provided between the connecting shaft 12 and the housing 7.

[0030] In this embodiment, by providing a third mechanical seal between the connecting shaft 12 and the housing 7, it is easy to maintain a good seal between the connecting shaft 12 and the housing 7.

[0031] As a technical optimization of this utility model, a controller is provided on the outer wall of the reactor body 1, and the drive motor 4 is electrically connected to the controller.

[0032] In this embodiment, the controller facilitates the normal operation of the drive motor 4.

[0033] The working principle and usage process of this utility model are as follows: In use, gas enters the main pipe 2 through the inlet pipe 3, and then enters the two branch pipes 9 through the horizontal pipe 8. It enters the reactor body 1 through the gas nozzles 11 on the outer wall of the multiple gas distribution pipes 10. The drive motor 4 is started, which drives the first synchronous pulley 5 to rotate, and then drives the second synchronous pulley 6 to rotate through the synchronous belt, which in turn drives the main pipe 2 to rotate. The main pipe 2 drives the shell 7 to rotate, which in turn drives the two branch pipes 9 to rotate in the horizontal direction. When the branch pipes 9 rotate in the horizontal direction, they further drive the second bevel gear 14 to roll along the first bevel gear 13, which in turn drives the branch pipes 9 to rotate in the vertical direction while revolving in the horizontal direction. The branch pipes 9 further drive the multiple gas distribution pipes 10 to rotate in the vertical direction while revolving in the horizontal direction, which causes the multiple gas nozzles 11 to perform three-dimensional compound motion, so that the gas is evenly introduced into the reactor body 1.

[0034] In the description of this utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
