Abstract
Description
Technical Field
[0001] This utility model relates to the field of distillation column technology, specifically to a gas-liquid distributor device for a distillation column. Background Technology
[0002] The gas-liquid distributor is one of the most crucial components inside a distillation column, and its performance directly impacts the column's separation efficiency. A high-performance gas-liquid distributor can reduce packing end effects, scale-up effects, and poor distribution, improving the gas-liquid distribution within the distillation column and enhancing its mass and heat transfer efficiency. Generally, the separation effect of a gas-liquid distributor is mainly reflected in the uniformity of liquid and gas distribution and the gas flow rate. Under certain flow rate conditions, the uniformity of gas-liquid distribution is the key to the distributor's performance.
[0003] In application number CN202121389519.5, a gas-liquid distributor device for a distillation column is disclosed. By driving the ring gear to rotate, the liquid phase dispersion tube can be rotated. When the liquid phase dispersion tube rotates, the nozzle on it will also rotate. The liquid sprayed from the nozzle will also diffuse in all directions under the action of centrifugal force, so that the liquid can fully contact the gas and improve the uniformity of liquid-gas mixing.
[0004] However, the gears used in this device drive the liquid phase dispersion tube to rotate. The gear transmission relies on the meshing of the tooth surfaces to transmit power. During long-term operation, the tooth surfaces will wear due to friction, resulting in a decrease in transmission accuracy, an increase in noise, and even faults such as tooth jamming or tooth breakage. This affects the stability and uniformity of the rotation of the liquid phase dispersion tube, thereby reducing the gas-liquid distribution effect. Furthermore, the liquid phase dispersion tube of this device is not easy to disassemble, making subsequent maintenance more troublesome. Therefore, a gas-liquid distributor device for a distillation column is proposed. Utility Model Content
[0005] The main objective of this invention is to provide a gas-liquid distributor device for a distillation column, which can effectively solve the problems in the background art.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A gas-liquid distributor device for a distillation column includes a base and a top plate. A bearing is rotatably mounted on the inner side of the base, and a connecting pipe is installed on the inner side of the bearing. A sleeve is fixedly sleeved on the outer side of the connecting pipe, and a liquid phase distribution pipe is fixedly connected to the outer side of the sleeve. The liquid phase distribution pipe communicates with the interior of the connecting pipe, and a threaded pipe is fixedly connected to the top end of the sleeve located at the center of the base.
[0008] The top of the top plate is rotatably mounted with a first pulley and a second pulley, which are connected by a belt drive. The second pulley is located at the center of the top plate.
[0009] By adopting the above technical solution, the device uses belt drive instead of traditional gear drive, avoiding wear and other faults caused by tooth surface friction, and ensuring the stability and accuracy of power transmission. The motor drives the first pulley, which drives the second pulley via the belt, and then the power is accurately transmitted to the liquid phase distribution pipe through the threaded connection, so that the liquid can be fully diffused under the action of centrifugal force.
[0010] Specifically, a connector is fixedly installed at the top of the second pulley, and the threaded tube has internal threads that are compatible with the bottom thread of the connecting tube. The top of the connecting tube passes through the top plate and is fixedly connected to the center of the second pulley and the bottom of the connector, and is internally connected.
[0011] By adopting the above technical solution, during the rotation of the second pulley, the joint fixed at its top rotates accordingly. The joint is fixedly connected to the connecting pipe, thereby driving the connecting pipe to rotate synchronously. The bottom end of the connecting pipe is threadedly connected to the threaded pipe. When the connecting pipe rotates, the rotational power is transmitted to the threaded pipe through the threaded connection, which in turn drives the sleeve and liquid phase distribution pipe connected to the threaded pipe to rotate, realizing the diffusion distribution of liquid under the action of centrifugal force. At the same time, the connecting pipe passes through the top plate and is connected to the center of the second pulley, ensuring the stability and accuracy of power transmission during the rotation process. Furthermore, its internal interconnection structure also ensures that the liquid can be smoothly transported from above to the liquid phase distribution pipe.
[0012] Specifically, a mounting base is fixedly installed on the top plate above the first pulley, and a motor is installed on the top of the mounting base. The output end of the motor passes through the mounting base and is fixedly connected to the center of the top of the first pulley.
[0013] By adopting the above technical solution, the mounting base is fixedly installed on the top plate, providing a stable mounting position for the motor. After the motor starts, its output end generates rotational power. Since the motor output end is fixedly connected to the center of the top of the first pulley, the rotational power of the motor can be directly transmitted to the first pulley, causing the first pulley to start rotating. After the first pulley rotates, the power is transmitted to the second pulley through the belt, thereby providing the initial power source for the rotation of the entire gas-liquid distributor device, ensuring that the liquid phase distribution tube can rotate normally to achieve the function of uniform gas-liquid distribution.
[0014] Specifically, both ends of the connecting pipe are fixedly connected to mounting heads, and movable blocks are movably inserted into the ends of the two mounting heads that are far apart from each other.
[0015] Specifically, the bearing has two slots on its inner side, which are used for inserting one end of the movable block.
[0016] By adopting the above technical solution, the mounting head is fixed at both ends of the connecting pipe, providing an installation position for the movable block. The movable block is movably inserted into the mounting head. During normal operation of the device, the movable block is inserted into the slot on the inner side of the bearing, which plays the role of positioning and supporting the connecting pipe, ensuring that the connecting pipe remains stable during rotation and will not shift or shake. This ensures that the liquid phase distribution pipe can rotate smoothly and achieve a uniform gas-liquid distribution effect. At the same time, the movable insertion design of the movable block also provides convenience for the disassembly and maintenance of the device.
[0017] Specifically, the base and the top plate are fixedly connected by connecting rods, and multiple connecting rods are provided.
[0018] By adopting the above technical solution
[0019] The beneficial effects of this utility model are:
[0020] The present invention discloses a gas-liquid distributor device for a distillation column. This device uses belt drive instead of traditional gear drive, avoiding wear and other failures caused by tooth surface friction, and ensuring the stability and accuracy of power transmission. The motor drives the first pulley, which drives the second pulley via the belt, and then the power is accurately transmitted to the liquid phase distribution pipe through a threaded connection, so that the liquid can be fully diffused under the action of centrifugal force.
[0021] The gas-liquid distributor device for a distillation column described in this utility model greatly simplifies the disassembly process through the design of the movable block cooperating with the slot and the threaded connection of the connecting pipe and the threaded pipe. During maintenance, it is only necessary to pull out the movable block and unscrew the connecting pipe to disassemble the liquid phase distribution pipe, the sleeve and the connecting pipe as a whole. Compared with traditional devices, it greatly reduces the maintenance difficulty and time cost, and effectively improves the equipment maintenance efficiency and service life.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0028] As one embodiment of this utility model, such as Figures 1-3 As shown, the gas-liquid distributor device for a distillation column according to the present invention includes a base 5 and a top plate 13. A bearing 4 is rotatably installed on the inner side of the base 5. A connecting pipe 3 is installed on the inner side of the bearing 4. A sleeve 2 is fixedly sleeved on the outer side of the connecting pipe 3. A liquid phase distribution pipe 1 is fixedly connected to the outer side of the sleeve 2. The liquid phase distribution pipe 1 communicates with the interior of the connecting pipe 3. A threaded pipe 17 is fixedly connected to the top end of the sleeve 2 located at the center of the base 5.
[0029] The top of the top plate 13 is rotatably mounted with a first pulley 7 and a second pulley 12. The first pulley 7 and the second pulley 12 are connected by a belt 10. The second pulley 12 is located at the center of the top plate 13.
[0030] In use, the bearing 4 is installed inside the base 5. Its main function is to support the connecting pipe 3 so that the connecting pipe 3 can rotate flexibly. The sleeve 2 fixedly connected to the outside of the connecting pipe 3 is connected to the liquid distribution pipe 1. When the connecting pipe 3 rotates, it can drive the sleeve 2 and the liquid distribution pipe 1 to rotate synchronously, so as to realize the function of liquid dispersion. The threaded pipe 17 is used to connect with the connecting pipe 14 to transmit the rotational power from the top plate 13. The first pulley 7 and the second pulley 12 rotatably installed on the top plate 13 are driven by the belt 10 to provide a power transmission path for the rotation of the device. The second pulley 12 is located in the center of the top plate 13, which facilitates the accurate transmission of power to the lower components.
[0031] The present invention also includes a connector 11 fixedly installed at the top of the second pulley 12, the threaded tube 17 having internal threads that are adapted to the bottom thread of the connecting tube 14, the top of the connecting tube 14 passing through the top plate 13 and being fixedly connected to the center of the second pulley 12 and the bottom of the connector 11 and communicating internally.
[0032] During use, as the second pulley 12 rotates, the connector 11 fixed at its top rotates accordingly. The connector 11 is fixedly connected to the connecting pipe 14, thereby driving the connecting pipe 14 to rotate synchronously. The bottom end of the connecting pipe 14 is threadedly connected to the threaded pipe 17. When the connecting pipe 14 rotates, the rotational power is transmitted to the threaded pipe 17 through the threaded connection, which in turn drives the sleeve 2 and the liquid distribution pipe 1 connected to the threaded pipe 17 to rotate, realizing the diffusion distribution of the liquid under the action of centrifugal force. At the same time, the connecting pipe 14 passes through the top plate 13 and is connected to the center of the second pulley 12, ensuring the stability and accuracy of power transmission during the rotation process. Furthermore, its internal interconnection structure also ensures that the liquid can be smoothly transported from above to the liquid distribution pipe 1.
[0033] The present invention also includes a mounting base 8 fixedly installed on the top plate 13 above the first pulley 7, a motor 9 installed on the top of the mounting base 8, and the output end of the motor 9 passing through the mounting base 8 and fixedly connected to the center of the top of the first pulley 7.
[0034] In use, the mounting base 8 is fixedly installed on the top plate 13, providing a stable mounting position for the motor 9. After the motor 9 is started, its output end generates rotational power. Since the output end of the motor 9 is fixedly connected to the center of the top of the first pulley 7, the rotational power of the motor 9 can be directly transmitted to the first pulley 7, causing the first pulley 7 to start rotating. After the first pulley 7 rotates, the power is transmitted to the second pulley 12 through the belt 10, thereby providing the initial power source for the rotation of the entire gas-liquid distributor device, ensuring that the liquid phase distribution pipe 1 can rotate normally to achieve the function of uniform gas-liquid distribution.
[0035] The present invention also includes that both ends of the connecting pipe 3 are fixedly connected to the mounting head 15, and the ends of the two mounting heads 15 that are far apart from each other are movably inserted with the movable block 16.
[0036] This utility model also includes a slot 18 provided on the inner side of the bearing 4. There are two slots 18, which are used for inserting one end of the movable block 16.
[0037] During use, the mounting head 15 is fixed at both ends of the connecting pipe 3 to provide an installation position for the movable block 16. The movable block 16 is movably inserted into the mounting head 15. When the device is running normally, the movable block 16 is inserted into the slot 18 inside the bearing 4, which plays the role of positioning and supporting the connecting pipe 3, ensuring that the connecting pipe 3 remains stable during rotation and will not shift or shake, ensuring that the liquid phase distribution pipe 1 can rotate smoothly and achieve a uniform gas-liquid distribution effect. At the same time, the movable insertion design of the movable block 16 also provides convenience for the disassembly and maintenance of the device.
[0038] It should be noted that the top of the movable block 16 has a groove to facilitate the removal of the movable block 16 from the slot 18, and the movable block 16 has a limiting mechanism inside the mounting head 15 to prevent the movable block 16 from detaching from the mounting head 15.
[0039] This utility model also includes a base 5 and a top plate 13 that are fixedly connected by a connecting rod 6, and the connecting rod 6 has multiple rods.
[0040] In use, after the motor 9 starts, its output end drives the first pulley 7 to rotate. Since the first pulley 7 and the second pulley 12 are connected by a belt 10, the second pulley 12 also rotates. When the second pulley 12 rotates, it drives the connecting pipe 14 to rotate through the connector 11. Because the connecting pipe 14 is threadedly connected to the threaded pipe 17, and the threaded pipe 17 is fixed on the sleeve 2, and the liquid phase distribution pipe 1 is fixedly connected to the outside of the sleeve 2, the liquid phase distribution pipe 1 will start to rotate under the drive of the connecting pipe 14. When the liquid phase distribution pipe 1 rotates, the liquid sprayed from its interior diffuses to the surroundings under the action of centrifugal force, thereby enabling the liquid to fully contact the gas, effectively improving the uniformity of liquid-gas mixing and contact, and improving the gas-liquid distribution effect.
[0041] The connecting pipe 14 and the threaded pipe 17 are connected by threads. When maintenance is required on components such as the liquid phase distribution pipe 1, the movable block 16 is first pulled out from the slot 18 inside the bearing 4, and then the connecting pipe 14 is unscrewed from the threaded pipe 17. This allows the liquid phase distribution pipe 1, the sleeve 2, and the connecting pipe 3 to be easily disassembled as a whole, greatly reducing the difficulty of later maintenance. Compared with the gear-driven and inconvenient disassembly device in the prior art, this design has obvious advantages in terms of maintenance.
[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
