Description

Technical Field

[0001] This utility model relates to the field of distillation column technology, and in particular to a tubular distillation column device. Background Technology

[0002] A well-known distillation column is a column-type gas-liquid contact device used for distillation. It utilizes the different volatility of the components in a mixture—that is, the different vapor pressures of the components at the same temperature—to transfer lighter components (low-boiling substances) from the liquid phase to the gas phase, while heavier components (high-boiling substances) from the gas phase transfer to the liquid phase, thus achieving separation. With the changing needs of people and the increasing specialization of industrial production, kilogram-scale distillation systems and experimental distillation systems have emerged.

[0003] Existing experimental distillation columns are generally fixed, integrated structures. In actual use, the number of stages in the distillation column cannot be flexibly adjusted according to experimental needs, thus reducing the flexibility of the equipment.

[0004] Therefore, it is necessary to provide a new tubular distillation column device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a tubular distillation column device.

[0006] The tubular distillation column device provided by this utility model includes: a base plate, on which the distillation column body is provided;

[0007] The distillation column body includes a demister section, a stripping section, and a tube heat exchange distillation section. Multiple sets of tube heat exchange distillation sections are provided. Adjacent demister sections, stripping sections, and tube heat exchange distillation sections are fixedly connected by bolts, and fixed brackets are provided on both sides of the outer wall of the stripping section.

[0008] The exterior of the distillation column body is provided with multiple sets of positioning components for supporting the installation of the tube heat exchange distillation section. The positioning components include docking half-rings, and two docking half-rings are provided and fixedly installed on the outer wall of the corresponding tube heat exchange distillation section and demister section by bolts.

[0009] Preferably, the top of the base plate is fixedly installed with symmetrically distributed support columns, the inside of the support columns is provided with through grooves, the top ends of the two support columns are installed with the same fixedly connected top ring, the opposite faces of the two support columns are respectively fixedly connected to the ends of the corresponding fixed frames, and the top ring is provided with a protective component to protect the distillation column plate.

[0010] Preferably, the protective component includes a mounting ring, which is fixedly connected to the top ring. The mounting ring is provided with a rubber ring on its outside, and the diameter of the rubber ring is greater than the diameter of the distillation column body.

[0011] Preferably, a plurality of evenly distributed springs are fixedly mounted between the rubber ring and the mounting ring, and an annular airbag is fixedly connected to the outer wall of the rubber ring.

[0012] Preferably, one of the outer walls of the docking semi-ring is provided with a fixedly connected support frame on both sides, and a fixedly connected magnetic block is provided inside the support frame. The outer wall of the magnetic block abuts against and attracts the inner wall of the through groove, and a fixedly connected protrusion is provided on the outer wall of the magnetic block.

[0013] Preferably, the end of the protruding rod away from the magnet extends to the outside of the support column, and a threaded limiting sleeve is fitted on the outer wall of the protruding rod, with the end of the limiting sleeve abutting against the outer wall of the support column.

[0014] Compared with related technologies, the tubular distillation column device provided by this utility model has the following advantages:

[0015] 1. This utility model adopts a modular structure for assembling the main body of the distillation column. During use, the operator can flexibly select the corresponding number of tube heat exchange distillation sections for assembly as needed, thereby changing the number of distillation stages in the later stage of the distillation column, thus improving the flexibility and scope of use of this device.

[0016] 2. Through the design of the protective components, the protruding rubber ring and annular airbag in the protective components can shield the top of the distillation column body during use. Thus, if the device is accidentally bumped or touched by the operator, causing it to tip over, the protruding rubber ring and annular airbag will be the first to contact the ground, thereby buffering the impact force generated when the device tipps over. This reduces the probability of damage to the device from the impact force, thus achieving device protection. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 5 The present invention provides a tubular distillation column device, which includes a bottom plate 1.

[0026] In the embodiments of this utility model, please refer to Figures 1 to 5 The base plate 1 is provided with a distillation column body 2; the distillation column body 2 includes a demister section 21, a stripping section 22 and a tube heat exchange distillation section 23. The tube heat exchange distillation section 23 is provided in multiple sets. The adjacent demister section 21, stripping section 22 and tube heat exchange distillation section 23 are fixedly connected by bolts, and the outer walls of the stripping section 22 are provided with fixed brackets 221 on both sides; the outside of the distillation column body 2 is provided with multiple sets of positioning components 3 for mounting and supporting the tube heat exchange distillation section 23. The positioning components 3 include docking half rings 31. There are two docking half rings 31, which are fixedly installed on the outer walls of the corresponding tube heat exchange distillation section 23 and demister section 21 by bolts.

[0027] It should be noted that by assembling the main body 2 of the distillation column into a split structure, the operator can flexibly select the corresponding number of tube heat exchange distillation sections 23 for assembly as needed during use, thereby changing the number of distillation stages in the later stage of the distillation column, thus improving the flexibility and scope of use of this device.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 5Symmetrically distributed support columns 11 are fixedly installed on the top of the base plate 1. Through grooves 111 are opened inside the support columns 11. The top ends of the two support columns 11 are fixedly connected to the same top ring 12. The opposite faces of the two support columns 11 are fixedly connected to the ends of the corresponding fixing frames 221. The top ring 12 is provided with a protective component 4 to protect the distillation column plate. The protective component 4 includes a mounting ring 41, which is fixedly connected to the top ring 12. The outside of the mounting ring 41 is provided with a rubber ring 43, and the diameter of the rubber ring 43 is greater than the diameter of the distillation column body 2. The fixing frame 221 between the rubber ring 43 and the mounting ring 41 is provided with multiple evenly distributed springs 42. The outer wall of the rubber ring 43 is provided with a fixedly connected annular air bladder 44.

[0029] It should be noted that by setting up a relatively large rubber ring 43 and annular airbag 44, when the device is tilted during use, the outer annular airbag 44 will be the first to contact the ground, thereby buffering the impact force when the device is tilted and contacting the ground, thus reducing the probability of the device being damaged by the impact force.

[0030] By using the spring 42, when the device tipps over, if the point of impact is exactly at the connection point of the spring 42 between the rubber ring 43 and the mounting ring 41, the spring 42 can absorb and buffer the impact force a second time, thereby helping to improve the buffering effect against the tipping impact force.

[0031] In the embodiments of this utility model, please refer to Figures 1 to 5 One of the connecting semi-rings 31 has a fixed support frame 32 on both sides of its outer wall. The support frame 32 has a fixed magnetic block 321 inside. The outer wall of the magnetic block 321 abuts against the inner wall of the through groove 111 and they attract each other. The outer wall of the magnetic block 321 has a fixed protrusion 322. The end of the protrusion 322 away from the magnetic block 321 extends to the outside of the support column 11. The outer wall of the protrusion 322 is fitted with a threaded limiting sleeve 323, and the end of the limiting sleeve 323 abuts against the outer wall of the support column 11.

[0032] It should be noted that: through the setting of the limiting sleeve 323, during the installation process, when the support frame 32 is fitted onto the outer wall of the support column 11, the support frame 32 can achieve mutual adsorption with the support column 11 through the internal magnetic block 321, thereby achieving the initial positioning of the support frame 32 and its connecting parts, thus making the positioning of the distillation column body 2 in the assembly process more accurate and convenient.

[0033] After the internal components of the positioning semi-ring are connected and fixed, the limiting sleeve 323 can be screwed onto the outer wall of the protruding rod 322. When the end of the limiting sleeve 323 abuts against the outer wall of the support column 11, the friction between the two abuts will achieve secondary fixation of the device installation, thereby improving the stability of the device installation.

[0034] The working principle of the tubular distillation column device provided by this utility model is as follows:

[0035] When using this device, the operator can first remove the corresponding tube heat exchange distillation section 23 as needed and move it to the position corresponding to the bottom stripping section 22.

[0036] At this time, the support frame 32 located in the external positioning component 3 will attract each other through the internal magnetic block 321 and the through groove 111 in the support column 11, thereby achieving the initial fixation of the tube heat exchange distillation section 23. Then, the tube heat exchange distillation section 23 can be fixed to the stripping section 22 below by bolts. Then, the limiting sleeve 323 can be taken out and screwed onto the outer wall of the protrusion 322 through the thread structure until the end of the limiting sleeve 323 abuts against the outer wall of the support column 11. The friction force when abutting can achieve secondary fixation.

[0037] By repeating the above steps, multiple tube-and-shell heat exchange distillation sections 23 can be assembled as needed. Finally, the demister end can be removed and connected to the uppermost tube-and-shell heat exchange distillation section 23 to complete the assembly of the device. This allows the number of distillation stages to be controlled according to the distillation requirements, thus improving the flexibility and scope of use of the device.

[0038] Furthermore, during use, when the device tilts due to external forces, the rubber ring 43 and the annular airbag 44 in the protective component 4 at the top of the support column 11 will press against the ground, thereby buffering the impact force between the device and the ground caused by the tilt, thus reducing the probability of damage to the device caused by the impact force when it tilts, and thus improving the protective effect of the device in later use.

[0039] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
