Description

Technical Field

[0001] This utility model relates to the field of packed tower technology, and in particular to a structured packing installation structure. Background Technology

[0002] Industrial packed towers are mass transfer devices widely used in chemical, petroleum, and environmental protection industries, primarily for separation processes such as distillation, absorption, desorption, and extraction. Their core structure includes the tower body, packing layer, liquid distributor and redistributor, gas inlet, and outlet. The packing, as a key component, provides a large specific surface area, promoting full contact between the gas and liquid phases, thereby improving mass transfer efficiency.

[0003] Currently, the packing material in existing industrial packed towers is stacked vertically and installed inside the tower body. This causes the liquid in the packed tower to flow easily along the tower wall (wall flow), resulting in insufficient wetting of the central area. It may also cause the liquid to form local channels (channel flow). Excessive stacking of packing material can also lead to excessively high total pressure drop inside the tower body, increasing energy consumption. In addition, the existing packing material is installed individually, which is inconvenient for subsequent disassembly, maintenance, or replacement, affecting work efficiency. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a structured packing installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a structured packing installation structure, comprising a tower body, a support ring fixed at the bottom of the inner wall of the tower body, a plurality of packing assemblies above the support ring, each packing assembly including an annular plate, and the annular plate of the lowest packing assembly fitting against the support ring, a plurality of packing plates fixed inside the annular plate, a support assembly between two adjacent packing assemblies, and the two adjacent packing assemblies being separated by the support assembly, an extrusion assembly inside the tower body and at the top of the uppermost packing assembly, a fixing assembly above the extrusion assembly, the fixing assembly being fixedly connected to the inner wall of the tower body, and an elastic assembly being fixedly connected between the fixing assembly and the extrusion assembly.

[0006] Furthermore, multiple hanging rings are fixed to the top of the inner sidewall of the annular plate.

[0007] Furthermore, the support assembly includes a bottom ring and a top ring. Multiple vertical tubes are fixed to the lower surface of the top ring. Vertical rods are slidably connected inside the vertical tubes. The bottom ends of the vertical rods are fixedly connected to the upper surface of the bottom ring. Locking bolts are threadedly connected to the side wall of the bottom end of the vertical tubes.

[0008] Furthermore, the bottom ring is fitted with the top of the annular plate of the lower packing assembly, and the top ring is fitted with the bottom of the annular plate of the upper packing assembly.

[0009] Furthermore, the fixing component includes a mounting frame, the sidewall of which is connected by a plurality of compression bolts through and via threads, the end of which is located outside the mounting frame and is fitted against the inner sidewall of the tower body.

[0010] Furthermore, a plurality of second crossbars are fixed to the inner sidewall of the mounting frame, and a second circular plate is fixed to the other end of the plurality of second crossbars. The extrusion assembly includes a pressure frame, and a plurality of first crossbars are fixed to the inner sidewall of the pressure frame. A first circular plate is fixedly connected to the other end of the plurality of first crossbars. The elastic assembly includes a slide rod fixed to the lower surface of the second circular plate. A circular tube is slidably connected to the surface of the slide rod. A spring is fixed to the bottom end of the slide rod and the inner bottom wall of the circular tube. The bottom end of the circular tube is fixedly connected to the first circular plate.

[0011] The beneficial effects of this utility model are:

[0012] 1. In use, this utility model provides a regular packing installation structure, which includes a tower body, a support ring, multiple packing assemblies, multiple support assemblies, a compression assembly, a fixing assembly, and an elastic assembly. The bottommost packing assembly is supported by the support ring. The multiple support assemblies provide support between adjacent packing assemblies. After the fixing assembly is fixed inside the tower body, the elastic assembly and the compression assembly compress the topmost packing assembly, allowing multiple packing assemblies to be installed inside the tower body. This eliminates the need for individual installation of each packing assembly, making the installation of the packing assemblies simple and convenient, and facilitating subsequent disassembly, replacement, or maintenance.

[0013] 2. In use, this utility model employs a structured packing installation with multiple supporting components to separate adjacent packing components, creating a buffer space between them. This reserved space allows the liquid to recombine between the two layers of packing components, resulting in a more even distribution to the lower packing component and increased mass transfer contact area. Furthermore, it interrupts the continuous gas phase pressure drop, preventing excessive total pressure drop due to excessive packing buildup, thus reducing energy consumption. The gas flow rate is adjusted as it passes through the space, reducing flow deviation and promoting uniform counter-current contact with the liquid. Additionally, the height of the supporting components is adjustable, allowing for reasonable adjustment of the space between adjacent packing components according to actual installation requirements.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown, a structured packing installation includes a tower body 1. A support ring 2 is fixed to the bottom of the inner wall of the tower body 1. Multiple packing assemblies 3 are provided above the support ring 2. Each packing assembly 3 includes an annular plate 31. The annular plate 31 of the lowermost packing assembly 3 is fitted with the support ring 2. Several packing plates 32 are fixed inside the annular plate 31. A support assembly 4 is provided between two adjacent packing assemblies 3, and the two adjacent packing assemblies 3 are separated by the support assembly 4. An extrusion assembly 5 is provided inside the tower body 1 and at the top of the uppermost packing assembly 3. A fixing assembly 6 is provided above the extrusion assembly 5. The fixing assembly 6 is fixedly connected to the inner wall of the tower body 1, and an elastic assembly 7 is fixedly connected between the fixing assembly 6 and the extrusion assembly 5.

[0024] Multiple hanging rings 33 are fixed to the top of the inner side wall of the annular plate 31.

[0025] In this embodiment, there are two hanging rings 33 inside the annular plate 31, and the two hanging rings 33 are symmetrically arranged, which makes it easy to lift the annular plate 31 from inside the tower body 1 through the hanging rings 33.

[0026] The support assembly 4 includes a bottom ring 41 and a top ring 42. Multiple vertical tubes 43 are fixed on the lower surface of the top ring 42. Vertical rods 44 are slidably connected inside the vertical tubes 43. The bottom end of the vertical rods 44 is fixedly connected to the upper surface of the bottom ring 41. A locking bolt 45 is threaded through the side wall of the bottom end of the vertical tubes 43 and rotatedly connected by a thread.

[0027] In this embodiment, one end of the locking bolt 45 inside the vertical tube 43 is in contact with the surface of the vertical rod 44. When the locking bolt 45 is loosened and the vertical rod 44 is not pressed, the vertical rod 44 can be slid up and down along the vertical tube 43 to adjust the height of the support assembly 4. After the adjustment is completed, the locking bolt 45 is tightened to press and fix the vertical rod 44.

[0028] The bottom ring 41 is fitted to the top of the annular plate 31 of the lower packing assembly 3, and the top ring 42 is fitted to the bottom of the annular plate 31 of the upper packing assembly 3.

[0029] The support component 4 separates the two adjacent packing components 3, so that a buffer space is formed between the two adjacent packing components 3.

[0030] The fixing component 6 includes a mounting frame 61, with a plurality of clamping bolts 64 threaded through the side wall of the mounting frame 61 and rotatably connected by threads. The end of the clamping bolt 64 located outside the mounting frame 61 is attached to the inner side wall of the tower body 1.

[0031] In this embodiment, after the mounting frame 61 is placed inside the tower body 1, the clamping bolt 64 is tightened to press against the inner wall of the tower body 1, thereby fixing the mounting frame 61 and making the installation of the fixing component 6 quicker and more convenient.

[0032] Multiple second crossbars 62 are fixed to the inner sidewall of the mounting frame 61. The other ends of the multiple second crossbars 62 are jointly fixed to a second circular plate 63. The extrusion assembly 5 includes a pressure frame 51, and multiple first crossbars 52 are fixed to the inner sidewall of the pressure frame 51. The other ends of the multiple first crossbars 52 are jointly fixed to a first circular plate 53. The elastic assembly 7 includes a slide rod 71 fixed to the lower surface of the second circular plate 63. A circular tube 72 is slidably connected to the surface of the slide rod 71. A spring 73 is jointly fixed to the bottom end of the slide rod 71 and the inner bottom wall of the circular tube 72. The bottom end of the circular tube 72 is fixedly connected to the first circular plate 53.

[0033] After the mounting frame 61 is fixed inside the tower body 1, the extrusion assembly 5 is pressed downward by the spring 73 under the extrusion force of the spring 73, thereby using the extrusion assembly 5 to extrude the uppermost packing assembly 3, thus fixing multiple packing assemblies 3 inside the tower body 1.

[0034] Working Principle: During installation, first place a packing assembly 3 on the surface of the support ring 2, then place a support assembly 4 with adjusted height on top of the packing assembly 3, and then place another packing assembly 3 on top of the support assembly 4, and so on. After the uppermost packing assembly 3 is placed, put the extrusion assembly 5 and the fixing assembly 6 into the tower body 1, and push the second circular plate 63 downward to compress the spring 73. Then tighten the extrusion bolts 64 of the fixing assembly 6 to fix it to the mounting frame 61, thus achieving rapid installation of the packing assembly 3. During use, the buffer space formed between the two packing assemblies 3 allows the liquid to re-collect between the two layers of packing assemblies 3, thereby evenly distributing it to the lower packing assembly 3 and increasing the mass transfer contact area. Secondly, it can interrupt the continuous gas phase pressure drop, avoiding excessive total pressure drop caused by excessive packing accumulation, thereby reducing energy consumption. The flow rate of the gas is adjusted when passing through the space, reducing flow deviation and promoting uniform countercurrent contact with the liquid.
