Abstract
Description
Technical Field
[0001] This utility model relates to the field of packed tower technology, and in particular to a graphite packed tower. Background Technology
[0002] In many industrial fields such as chemical engineering and environmental protection, gas-liquid mass transfer processes are crucial operations, such as gas purification and liquid absorption, and packed towers are important equipment for realizing these processes. Traditional packed towers have some limitations in structure and design.
[0003] Some traditional packed towers have inadequate gas inlet methods, resulting in uneven gas distribution within the tower and insufficient gas-liquid contact. This reduces mass transfer efficiency and leads to poor gas purification or liquid absorption, requiring additional equipment or extended reaction times to achieve the desired treatment effect, thus increasing production costs and energy consumption. Regarding spraying, some packed towers have simple spray component designs, resulting in uneven liquid spraying and an inability to form fine, widely distributed droplets. This further affects the gas-liquid contact area, limiting the improvement of mass transfer efficiency. Furthermore, traditional packed towers often rely on complex electrical control systems or frequent manual operation for liquid level control, which not only increases equipment costs and maintenance difficulty but also makes inaccurate control possible, affecting the stability and reliability of the entire production process.
[0004] Therefore, it is necessary to provide a new graphite packed tower to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a graphite packed tower.
[0006] This utility model provides a graphite packed tower, characterized in that it includes a packed tower, an air inlet assembly, a spray assembly, a drain pipe, an exhaust pipe, a first packed grid, a second packed grid, a enclosure, and an opening and closing assembly. The bottom of the packed tower is connected to the drain pipe, and the opening and closing assembly is installed inside the drain pipe. The air inlet assembly is installed at the bottom of the inner side of the packed tower, and the spray assembly is installed at the top of the inner side of the packed tower. The first packed grid is fixedly installed inside the packed tower, the second packed grid is installed above the first packed grid, and the enclosure is installed at the bottom of the second packed grid.
[0007] Preferably, the enclosure is funnel-shaped.

[0013] Compared with related technologies, the graphite packed tower provided by this utility model has the following beneficial effects:
[0014] This utility model provides a graphite packed tower. Through an inlet assembly, gas is uniformly introduced into the bottom of the tower via an annular gas pipe and multiple downward-facing jet pipes arranged in a circular array, providing excellent conditions for sufficient gas-liquid contact and mass transfer, effectively improving mass transfer efficiency. The spray assembly uses a spiral spray pipe, where liquid is uniformly sprayed downwards through multiple nozzles to form fine droplets, greatly increasing the gas-liquid contact area and further enhancing the mass transfer effect. The opening and closing assembly utilizes the buoyancy of a float ball during liquid level changes and the tension of a spring to achieve automatic on / off control of the drain pipe. This eliminates the need for complex electrical systems or frequent manual operation, reducing equipment costs and maintenance difficulty, and ensuring stable and reliable production processes. Furthermore, this graphite packed tower has a simple overall structure and is easy to operate. By rationally setting the structure and positional relationships of each component, the overall gas-liquid mass transfer efficiency is comprehensively improved. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please refer to the following: Figures 1-4 ,in, Figure 1 A three-dimensional structural diagram of the graphite packed tower provided by this utility model; Figure 2 This is a cross-sectional structural diagram of the graphite packed tower provided by this utility model; Figure 3 A schematic diagram of the spraying mechanism provided by this utility model; Figure 4 Provided by this utility model Figure 2 Enlarged structural diagram at point A in the middle.
[0022] In the specific implementation process, such as Figures 1-4 As shown, a graphite packed tower includes a packed tower 1, an air inlet assembly, a spray assembly, a drain pipe 2, an exhaust pipe 3, a first packed grid 4, a second packed grid 5, a enclosure 6, and an opening and closing assembly. The bottom of the packed tower 1 is connected to the drain pipe 2, and the opening and closing assembly is installed inside the drain pipe 2. The air inlet assembly is installed at the bottom inside the packed tower 1, and the spray assembly is installed at the top inside the packed tower 1. The first packed grid 4 is fixedly installed inside the packed tower 1, and the second packed grid 5 is installed above the first packed grid 4. The enclosure 6 is installed at the bottom of the second packed grid 5.
[0023] A support frame 12 is provided at the bottom of the packed tower 1, which provides stable support for the packed tower 1 and ensures that the packed tower 1 remains stable during operation without shaking or tilting. A packing loading and unloading port 13 is provided on the outer side of the packed tower 1, which is used to facilitate the loading and unloading of graphite packing 14 inside the packed tower 1, making it convenient for equipment maintenance and repair.
[0024] The gas inlet assembly is used to introduce gas into the packed tower 1. An inlet pipe 7 is connected to the bottom of the outer side of the packed tower 1, serving as the gas inlet channel. An annular gas pipe 8 is connected to the inlet pipe 7, surrounding the bottom of the packed tower 1. Several jet pipes 9 arranged in a circular array are connected to the bottom of the annular gas pipe 8, with the jet direction of the jet pipes 9 pointing downwards. When the gas enters from the inlet pipe 7, it first enters the annular gas pipe 8, and then is evenly sprayed out towards the bottom of the packed tower 1 through the multiple jet pipes 9, ensuring uniform gas distribution at the bottom of the packed tower 1 and providing favorable conditions for subsequent sufficient contact and mass transfer with the liquid.
[0025] The spray assembly is used to spray liquid into the packed tower 1, allowing it to contact the gas in a countercurrent flow to achieve mass transfer. An inlet pipe 10 is connected to the top of the outer side of the packed tower 1, serving as the liquid inlet channel. The inlet pipe 10 is connected to a spiral spray pipe 11, which spirally surrounds the top of the inner side of the packed tower 1. Several spray nozzles are located at the bottom of the spiral spray pipe 11. When the liquid enters the spiral spray pipe 11 from the inlet pipe 10, it is evenly sprayed downwards through these nozzles, forming fine droplets. This increases the contact area between the liquid and gas, improving mass transfer efficiency.
[0026] A first packing grid 4 is fixedly installed inside the packed tower 1. The first packing grid 4 is located in the lower middle part of the packed tower 1 and serves to support the graphite packing 14. A second packing grid 5 is installed above the first packing grid 4 and is arranged parallel to the first packing grid 4. A funnel-shaped baffle 6 is installed at the bottom of the second packing grid 5. Its function is to concentrate and guide the liquid below the second packing grid 5 to the bottom, preventing the liquid from accumulating locally.
[0027] Graphite packing 14 is provided above both the first packing grid 4 and the second packing grid 5. The graphite packing 14 has good chemical stability and mass transfer performance. When the gas and liquid pass through the graphite packing 14, they can have full contact and mass transfer on the packing surface, so as to achieve the purpose of gas purification and liquid absorption.
[0028] A drain pipe 2 is connected to the bottom of the packed tower 1, and is used to discharge the liquid after reaction inside the packed tower 1. An opening and closing assembly is installed inside the drain pipe 2 to control the opening and closing of the drain pipe 2. A support ring 15 is fixedly installed inside the drain pipe 2, providing fixed support for a spring 16. A spring 16 is fixedly connected to the support ring 15, and a float 17 is fixedly installed on the top of the spring 16. Under normal operating conditions, when the liquid level inside the packed tower 1 is low, the float 17 is in a low position under its own weight and the tension of the spring 16, and the top of the drain pipe 2 is unobstructed. However, due to the low liquid level, a large amount of liquid will not flow out. When the liquid level inside the packed tower 1 rises, the float 17 gradually rises under the buoyancy of the liquid. When the liquid level rises to a certain level, the float 17 blocks the top of the drain pipe 2, preventing further liquid outflow, thus automatically controlling the liquid level. When drainage is required, the liquid level in the packed tower 1 can be lowered manually or by other means. The float 17 descends under the tension of the spring 16, and the drain pipe 2 is unblocked again, allowing the liquid to be discharged.
[0029] The top of the packed tower 1 is connected to an exhaust pipe 3, which is used to discharge the treated gas, so that the purified gas can be smoothly discharged from the packed tower 1 and enter the subsequent treatment or emission stage.
[0030] The graphite packed tower of the present invention achieves efficient mass transfer of gas and liquid by rationally setting the structure and positional relationship of each component, and has the advantages of simple structure, convenient operation and high mass transfer efficiency.
[0031] 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.
