Description

Technical Field

[0001] This utility model relates to the field of gas separation and adsorption devices, and in particular to an aluminum alloy modular gas separation adsorption tower. Background Technology

[0002] Air separation technology primarily relies on the differences in molecular activity and size among components in the air, such as nitrogen, oxygen, argon, and helium. It achieves gas separation and purification through pressure swing adsorption (PSA) or cryogenic processes, thereby providing high-purity protective or reactive gases for industrial applications. Among these, PSA is widely used due to its flexible operation and low energy consumption.

[0003] Currently, the adsorption towers commonly used in this field are typically made of carbon steel, assembled through processes such as bending, welding, and cutting. These devices often have a small diameter-to-height ratio and a large internal volume. While this results in lower manufacturing costs, the welded structure limits the overall structural uniformity and airflow distribution, leading to poor gas flow paths within the tower and insufficient utilization of the adsorbent. The consequences are often high energy consumption, low gas separation efficiency, and complex subsequent processing, indicating significant room for improvement in overall economic efficiency and energy effectiveness.

[0004] To address the aforementioned problems, this invention proposes a modular adsorption tower made of aerospace-grade aluminum alloy and manufactured using high-temperature extrusion injection molding technology. This structure has a large diameter-to-height ratio, which significantly improves airflow distribution and increases the contact efficiency between the gas and the adsorbent (such as carbon molecular sieves or zeolite molecular sieves). This allows for higher oxygen or nitrogen production under the same volume conditions, while simultaneously reducing energy consumption and operating costs, extending the adsorbent's lifespan and gas conversion efficiency, aligning with the industry trend of energy conservation and environmental protection. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the main purpose of this utility model is to provide an aluminum alloy modular gas separation equipment adsorption tower that is flexible in configuration, highly efficient and reliable, and can reduce energy consumption.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy modular gas separation equipment adsorption tower, comprising one or more aluminum alloy adsorption cylinders and cover plates disposed at the top and bottom of the aluminum alloy adsorption cylinders; the aluminum alloy adsorption cylinders are filled with carbon molecular sieves or zeolite molecular sieves, and the upper and lower outlets of the aluminum alloy adsorption cylinders are provided with nylon perforated plates that can compact the carbon molecular sieves or zeolite molecular sieves; the cover plates include mounting holes corresponding to the aluminum alloy adsorption cylinders and gas flow channels located below the mounting holes, and one end of the gas flow channels is sealed by a rear cap.

[0007] Preferably, the aluminum alloy adsorption cylinder is integrally formed.

[0008] Preferably, each cover plate can be connected to one or more aluminum alloy adsorption cylinders at the same time.

[0009] Preferably, the cover plate is provided with an assembly groove corresponding to the aluminum alloy adsorption cylinder, and a sealing ring is provided in the assembly groove.

[0010] Preferably, it also includes a base, and a cover plate located below all the aluminum alloy adsorption cylinders is fixedly connected to the base.

[0011] This invention offers the following advantages over existing technologies: It utilizes aerospace-grade aluminum alloy material and employs a high-temperature extrusion injection molding process to create a modular adsorption cylinder structure with an optimized diameter-to-height ratio. Gas flow channels are integrated through upper and lower cover plates, forming a highly efficient and reliable gas separation adsorption tower. This structure has a large diameter-to-height ratio, which significantly improves airflow distribution and enhances the contact efficiency between the gas and the adsorbent (such as carbon molecular sieves or zeolite molecular sieves). This allows for higher oxygen or nitrogen production under the same volume conditions, while simultaneously reducing energy consumption and operating costs, extending the adsorbent's lifespan, and increasing gas conversion efficiency, aligning with the industry trend of energy conservation and environmental protection.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1As shown, an aluminum alloy modular gas separation adsorption tower includes one or more aluminum alloy adsorption cylinders 1 and cover plates 2 disposed at the top and bottom of the aluminum alloy adsorption cylinders 1. The aluminum alloy adsorption cylinders 1 are filled with carbon molecular sieves or zeolite molecular sieves. The upper and lower outlets of the aluminum alloy adsorption cylinders 1 are provided with nylon perforated plates 3 that can compact the carbon molecular sieves or zeolite molecular sieves. The cover plate 2 includes mounting holes corresponding to the aluminum alloy adsorption cylinders 1 and a gas flow channel 21 located below the mounting holes. One end of the gas flow channel 21 is sealed by a rear cap 4. The aluminum alloy adsorption cylinders 1 are integrally formed. Each cover plate 2 can connect one or more aluminum alloy adsorption cylinders 1 simultaneously. The cover plate 2 is provided with an assembly groove 22 corresponding to the aluminum alloy adsorption cylinders 1. A sealing ring is provided in the assembly groove 22. The assembly groove 22 ensures installation accuracy, and the sealing groove ensures sealing performance. The aluminum alloy adsorption cylinders 1 are fixedly connected to the cover plate 2 by screws. It also includes a base 5, and a cover plate 2 located below all aluminum alloy adsorption cylinders 1 is fixedly connected to the base 5.

[0016] The core principle of this patented technology is to use aerospace aluminum alloy material to manufacture a modular adsorption cylinder structure with an optimized diameter-to-height ratio through a high-temperature extrusion injection molding process, and to integrate gas flow channels 21 through upper and lower cover plates 2 to form a highly efficient and reliable gas separation adsorption tower.

[0017] Its technological advantages are mainly reflected in the following aspects: First, the one-piece molded aluminum alloy adsorption cylinder 1 avoids the problems of potential weld leakage and uneven internal airflow distribution that exist in traditional carbon steel welding towers, which greatly improves the structural integrity and sealing of the equipment. In addition, the aluminum alloy material is lightweight and corrosion resistant, which extends the service life of the equipment.

[0018] Secondly, the unique modular design allows multiple adsorption cylinders to be connected in parallel on a single cover plate, making the system configuration flexible and easy to expand or adjust according to gas volume requirements, effectively improving equipment adaptability and space utilization.

[0019] Third, the molecular sieve inside the adsorption cylinder is compacted by nylon perforated plates 3, and combined with the optimized diameter-to-height ratio design, the airflow distribution is more uniform, and the gas and adsorbent are in more sufficient contact, thereby significantly improving the separation efficiency and purity of oxygen or nitrogen, reducing adsorbent pulverization loss and system pressure drop, and saving energy consumption and operating costs.

[0020] Finally, the overall structure is compact and easy to install and maintain. The gas flow channel 21 integrated by the cover plate 2 realizes efficient gas collection and distribution, reduces external pipeline connections, not only reduces the risk of leakage, but also further improves the reliability and economy of the equipment.

[0021] This device achieves a balance between high performance, energy saving, long lifespan, and low operating cost, making it particularly suitable for industrial applications involving pressure swing adsorption (PSA) to produce high-purity nitrogen and oxygen.
