Description

Technical Field

[0001] The utility model relates to the technical field of distillation towers, in particular to a combined distillation tower. Background Art

[0002] The combined distillation tower mainly relies on its internal plate structure to achieve the balance of liquid flow. There are multiple holes on the plate structure. The liquid enters the tower plate from the bottom of the tower through these holes, and then flows to the upper tower plate through the holes on the tower plate. This process separates the flow of liquid between the tower plates, and the liquid flow on each tower plate is kept balanced. The effect of this balanced flow can maximize the efficiency of the tower plate and ensure the effective implementation of the separation process. At the same time, during the distillation process, the liquid forms a thin liquid film on the tower plate. By contacting with the steam from above, the liquid evaporates to produce steam, thereby realizing the separation of liquid components. The tower plate holes and structure on the distillation tower plate can effectively promote the contact between steam and liquid and improve the separation effect. In order to adapt to different production requirements and operating conditions, different numbers of plate components need to be installed.

[0003] However, most of the existing plate-type distillation towers are plugged into the inside of the tower body. When a plate-type structure is needed, the original tower body needs to be cut, and then the new tower plate is installed, and then the plate-type structure is installed on the tower plate. Due to the large volume of the tower body, it is extremely inconvenient to cut the tower body, and the required processing cycle is long. The overall operation difficulty is also high. Therefore, there is a need for a distillation tower that no longer relies on cutting the tower body to add a plate group. Based on the above viewpoint, a technician in this field provides a combined distillation tower. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a combined distillation tower is proposed. The combined distillation tower can directly increase the plate components inside the distillation tower through a retractable plate structure. When the contact surface area of ​​the gas-liquid two phases needs to be increased, the driving motor directly controls the rotation of the driving worm, and then drives the driving shaft to rotate through the driving worm gear, so that the winding plate rolled up on the driving shaft is unfolded, thereby improving the separation efficiency, so that the distillation tower can adapt to different production requirements and operating conditions, and increase the operational flexibility and convenience.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A combined distillation tower, comprising a distillation tower body, a condensation reflux port, a raw material feed port, a steam feed port, a gas phase discharge port, a liquid phase discharge port, a packing pressing device and a plurality of fixed plate structures, wherein the plurality of fixed plate structures are clamped on the inner side wall of the distillation tower body and are staggeredly distributed, the rear side wall of the distillation tower body is fixedly connected with a rear driving tower, the rear driving tower comprises a driving tower body, two driving motors and two driving worms, the two driving motors are mounted on the upper side wall of the driving tower body and are mirror-symmetrically distributed, the two driving worms are respectively connected to the active ends of the two driving motors through couplings, the threads of the two driving worms turn in opposite directions, and the threads of the two driving worms are meshed with a retractable plate structure, the retractable plate structure comprises a plate frame driving worm wheel, a driving shaft and a rewinding plate, the driving shaft is fixedly connected to the center of the front side wall of the plate frame driving worm wheel and is connected to the front and rear side walls of the distillation tower body through bearings, and the rewinding plate is wound on the driving shaft;

[0007] Through the above technical solution, it is no longer necessary to install plate components by cutting and welding. When the contact surface area of ​​the gas-liquid two phases needs to be increased, the drive motor directly controls the rotation of the drive worm, and then drives the drive shaft to rotate through the drive worm gear, thereby unfolding the winding plate wound on the drive shaft, thereby improving the separation efficiency, allowing the distillation tower to adapt to different production requirements and operating conditions, increasing operational flexibility and convenience.

[0008] Furthermore, the plurality of winding plates are staggered and every two adjacent winding plates are arranged between two adjacent fixed plate structures;

[0009] Through the above technical solution, the plate structure in the distillation tower can form a staggered distribution before and after the winding plate is wound, so that the rollable plate structure will not affect the gas-liquid two-phase contact effect of the distillation tower before and after winding.

[0010] Furthermore, a plurality of positioning clips are fixedly connected to the inner walls on both sides of the distillation tower body, and every two positioning clips located on the same transverse axis are arranged at the front and rear ends of the winding plate at the same height therewith;

[0011] Through the above technical solution, the positioning clamp can prevent the winding plate from curling up as a whole after unwinding due to long-term winding, and the positioning clamp can ensure the flatness of the surface of the winding plate after unwinding.

[0014] Furthermore, a packing pressing device is tightly pressed above the packing layer at the bottom of the distillation tower body;

[0015] Through the above technical solution, the packing pressing device can prevent the packing bed layer from loosening or jumping under the action of the rising airflow, and the packing layer is pressed by the packing pressing device's own deadweight.

[0016] Furthermore, the bottoms of the two driving worms are meshed with an adjustable clamping assembly, and the adjustable clamping assembly includes a clamping end worm wheel, a clamping end shaft rod and an elastic member, the clamping end shaft rod is fixedly connected to the center of the clamping end worm wheel, and the elastic member is sleeved at the middle position of the clamping end shaft rod;

[0017] Through the above technical solution, when the retractable plate structure is unfolded, the contact area between the gas in the tower and the plate structure increases, and the vibration of the packing layer caused by the vibration of the tower body increases, resulting in the loosening of the packing layer. Therefore, while driving the retractable plate structure to unfold, the elastic part is driven to rotate through the clamping end shaft rod, and then the deformation of the elastic part provides a greater downward pressure on the packing clamping device, thereby avoiding the loosening of the packing bed layer caused by the increase in the contact area between the gas phase and the plate structure.

[0018] Further, the elastic member is tightly pressed on the packing pressing device, and one side of the elastic member is raised;

The rear side wall of the distillation tower body 1 is fixedly connected with the rear driving tower 700. The rear driving tower 700 includes a driving tower body 701, two driving motors 702 and two driving worms 703. The two driving motors 702 are installed on the upper side wall of the driving tower body 701 and are distributed in a mirror-symmetrical manner. The two driving worms 703 are respectively connected to the movable ends of the two driving motors 702 through couplings. The threads of the two driving worms 703 turn in opposite directions. The threads of the two driving worms 703 are meshed with a retractable plate structure 800. The retractable plate structure 800 includes a plate frame driving worm gear 801, a driving shaft 802 and a winding plate 803. The driving shaft 802 is fixedly connected to the center of the front side wall of the plate frame driving worm gear 801 and is connected to the front and rear side walls of the distillation tower body 1 through bearings. The winding plate 803 is wound on the driving shaft 802.

[0035] A plurality of winding plates 803 are staggered and every two adjacent winding plates 803 are arranged between two adjacent fixed plate structures 11. A plurality of positioning clips 12 are fixedly connected to the inner walls of the front and rear sides of the distillation tower body 1. Every two positioning clips 12 located on the same transverse axis plane are arranged at the front and rear ends of the winding plate 803 at the same height therewith. The positioning clips 12 can prevent the winding plate 803 from being warped as a whole after unwinding due to long-term winding. The positioning clips 12 can ensure that the surface of the winding plate 803 is flat after unwinding, so that the plate structure in the distillation tower can be staggered before and after the winding plate 803 is wound, so that the winding plate 803 can be wound. The rolled plate structure 800 will not affect the gas-liquid two-phase contact effect of the refiner before and after winding. The combined distillation tower can directly increase the plate components inside the distillation tower through the rollable plate structure 800, and there is no need to install the plate components by cutting and welding. When the contact surface area of ​​the gas-liquid two-phase needs to be increased, the driving motor 702 directly controls the driving worm 703 to rotate, and then drives the driving shaft 802 to rotate through the driving worm gear, so as to unfold the winding plate 803 rolled up on the driving shaft 802, thereby improving the separation efficiency, so that the distillation tower can adapt to different production requirements and operating conditions, and increase the operational flexibility and convenience.

Therefore, while driving the retractable plate structure 800 to unfold, the elastic member 1003 is driven to rotate through the compression end shaft 1002, and then the deformation of the elastic member 1003 provides a greater downward pressure on the packing clamping device 9, thereby avoiding the loosening of the packing bed layer caused by the increase in the contact surface between the gas phase and the plate structure. The elastic member 1003 is tightly pressed on the packing clamping device 9, and one side of the elastic member 1003 is raised, and the raised end of the elastic member 1003 provides a greater downward pressure for the packing clamping device 9.

[0037] Working principle: The combined distillation tower can directly increase the plate components inside the distillation tower through the retractable plate structure 800, and there is no need to install the plate components by cutting and welding. When the contact surface area of ​​the gas-liquid two phases needs to be increased, the driving motor 702 directly controls the driving worm 703 to rotate, and then drives the driving shaft 802 to rotate through the driving worm gear, so that the winding plate 803 wound on the driving shaft 802 is unfolded, and several winding plates 803 are staggered and every two adjacent winding plates 803 are arranged between two adjacent fixed plate structures 11, so that the plate structure in the distillation tower can form a staggered distribution before and after the winding plate 803 is rolled up, so that the retractable plate structure 800 can be staggered. The gas-liquid two-phase contact effect of the refinery tower will not be affected before and after winding, thereby improving the separation efficiency, allowing the distillation tower to adapt to different production requirements and operating conditions, increasing operational flexibility and convenience. When the retractable plate structure 800 is unfolded, the contact area between the gas in the tower and the plate structure increases, and the vibration of the packing layer caused by the vibration of the tower body increases, resulting in loosening of the packing layer. Therefore, while driving the retractable plate structure 800 to unfold, the elastic part 1003 is driven to rotate through the clamping end shaft 1002, and then the deformation of the elastic part 1003 provides a greater downward pressure on the packing clamping device 9, thereby avoiding the loosening of the packing bed due to the increase in the contact area between the gas phase and the plate structure.
