Abstract
Description
Technical Field
[0001] This utility model relates to the field of distillation column packing technology, specifically to a packing structure for the interior of a distillation column. Background Technology
[0002] A distillation column is a key piece of equipment used to separate mixed liquids. It consists of a column body, trays, or packing. After the mixed liquid enters the column, it undergoes multiple partial vaporization and partial condensation processes. Lighter components rise continuously, while heavier components gradually sink, thus achieving the separation of substances with different boiling points. Distillation columns are widely used in many fields such as petroleum refining and chemical engineering to obtain high-purity products. Their efficient separation capabilities are of great significance for improving product quality and effectively utilizing resources in industrial production. Packing, as a major component of the distillation column, plays a crucial role in the distillation operation. Traditional bulk packing structures are usually Pall ring structures, which have insufficient contact area between the liquid and gas, resulting in distillation efficiency that does not meet design requirements. Utility Model Content
[0003] The purpose of this invention is to provide a packing structure for the internal structure of a distillation column, in order to solve the problem mentioned in the background art that the traditional bulk packing structure is usually a Pall ring structure, which has insufficient contact area between liquid and gas on the packing, resulting in the distillation efficiency not meeting the design requirements.

[0005] Preferably, the upper main protrusion and the lower main protrusion are integrally formed with the ring body through a shearing and bending process. The sidewall of the ring body has a main window at the position corresponding to the upper main protrusion and the lower main protrusion. Both sides of the upper main protrusion and the lower main protrusion are fixedly connected to the sidewall of the ring body.
[0006] Preferably, the upper sub-protrusion is integrally formed with the upper main protrusion through a shearing and bending process, and the two sides of the upper sub-protrusion are fixedly connected to the upper main protrusion.
[0007] Preferably, the lower sub-protrusion is integrally formed with the lower main protrusion through a shearing and bending process, and the two sides of the lower sub-protrusion are fixedly connected to the lower main protrusion.
[0008] Preferably, a secondary window is provided on the upper main protrusion at the position corresponding to the upper secondary protrusion and on the lower main protrusion at the position corresponding to the lower secondary protrusion.

[0016] 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.
[0017] Please see Figure 1-5This utility model provides an internal packing structure for a distillation column, including a ring body 1. The upper end of the side wall of the ring body 1 is recessed inward and has an upper main protrusion 2. The lower end of the side wall of the ring body 1 is recessed inward and has a lower main protrusion 3. There are four upper main protrusions 2 and four lower main protrusions 3. The upper main protrusions 2 and the lower main protrusions 3 are staggered at a 45° angle. The middle position of the upper main protrusion 2 is recessed outward and has an upper secondary protrusion 4. The middle position of the lower main protrusion 3 is recessed outward and has a lower secondary protrusion 5. The upper and lower outer edges of the ring body 1 are respectively provided with an upper edge 6 and a lower edge 7. Both the upper edge 6 and the lower edge 7 are provided with through grooves 8.
[0018] In use, by creating an upper main protrusion 2 and a lower main protrusion 3 on the ring body 1, and setting the upper main protrusion 2 and the lower main protrusion 3 at a 45° angle, the outer surface of the side wall of the ring body 1 in contact with the liquid is increased, thereby increasing the flow time of the liquid inside the packing. Upper secondary protrusions 4 and lower secondary protrusions 5 are also set on the upper main protrusion 2 and the lower main protrusion 3, respectively, to further increase the outer surface of the side wall of the ring body 1 in contact with the liquid, thereby increasing the flow time of the liquid inside the packing and improving the contact area and contact time between the liquid and the gas. Upper edges 6 and lower edges 7 are set at the upper and lower ends of the ring body 1, respectively, to increase the outer diameter of the upper and lower ends of the ring body 1 and avoid the occurrence of nesting between ring bodies 1 with similar dimensions. Through grooves 8 are set on the upper edges 6 and lower edges 7, which also increases the outer surface of the side wall of the ring body 1 in contact with the liquid and increases the flow time of the liquid inside the packing.
[0019] The upper main protrusion 2 and the lower main protrusion 3 are integrally formed with the ring body 1 through a shearing and bending process. The side wall of the ring body 1 is provided with main windows 9 at the positions corresponding to the upper main protrusion 2 and the lower main protrusion 3. Both sides of the upper main protrusion 2 and the lower main protrusion 3 are fixedly connected to the side wall of the ring body 1. The upper main protrusion 2 and the lower main protrusion 3, which are integrally formed, improve the overall strength of the packing structure. The main windows 9 are provided at the positions corresponding to the upper main protrusion 2 and the lower main protrusion 3 on the side wall of the ring body 1, so that the liquid can flow between the ring bodies 1 through the main windows 9.
[0020] The upper sub-protrusion 4 is integrally formed with the upper main protrusion 2 through a shearing and bending process. The two sides of the upper sub-protrusion 4 are fixedly connected to the upper main protrusion 2, thereby improving the connection strength between the upper sub-protrusion 4 and the upper main protrusion 2 and enhancing the overall strength of the filler structure.
[0021] The lower sub-protrusion 5 is integrally formed with the lower main protrusion 3 through a shearing and bending process. The two sides of the lower sub-protrusion 5 are fixedly connected to the lower main protrusion 3, thereby improving the connection strength between the lower sub-protrusion 5 and the lower main protrusion 3 and enhancing the overall strength of the filler structure.
[0022] Sub-windows 10 are provided on the upper main protrusion 2 at the position corresponding to the upper secondary protrusion 4 and on the lower main protrusion 3 at the position corresponding to the lower secondary protrusion 5. The sub-windows 10 on the upper main protrusion 2 and the lower main protrusion 3 improve the flow of liquid between the rings 1.
