Description

TECHNICAL FIELD

[0001] The utility model relates to gas filter technical field especially, it is a kind of device suitable for hydrogen filtration, it is high-pressure gas filter device with quick installation and disassembly function, multilayer filter structure and high -efficient flow guide design. BACKGROUND

[0002] In modern industrial production, hydrogen as an important clean energy, has wide application in chemical industry, electronics, metallurgy and other fields. The purity and cleanliness of hydrogen are crucial to its application effect in various fields, therefore, efficient and reliable hydrogen filter device is particularly important. The main function of hydrogen filter device is to remove impurities in hydrogen, to ensure its efficiency and safety in various applications, especially in high-pressure environment, the flow characteristics of hydrogen and the removal efficiency of impurities will be more challenging, therefore, the design and performance requirements of high-pressure hydrogen filter device are more stringent.

[0003] However, traditional gas filter device has many problems in practical application. The multilayer filter structure in traditional gas filter device usually adopts fixed design, when the filter layer needs to be replaced, it must be stopped and rely on special tools for disassembly, the operation is cumbersome, and the maintenance efficiency is low. This not only increases the downtime of equipment, but also increases the maintenance cost, seriously affecting the continuity of production and economic benefits.

[0004] In terms of sealing performance, the sealing ring material of traditional gas filter device is poor, and it is easy to age in high-pressure environment, leading to gas leakage. This not only reduces the performance of the filter device, but also may cause safety accidents, threatening personnel and equipment.

[0005] The gas inlet design of traditional gas filter device is relatively simple, and it is easy to form "channeling" phenomenon. So-called "channeling" is the formation of local concentrated flow channel in the filter device, which leads to the insufficient use of some filter layers, reducing the filtration efficiency. This not only affects the filtration effect, but also may cause local overload of filter layer, shortening its service life.

[0006] Although some existing patents (such as CN202122139718.7, CN202410808164.0) propose some modular filter structure to improve the shortcomings of traditional filter device, these patents still do not solve the core problems of quick locking, sealing reinforcement and flow optimization. In practical application, the lack of quick locking device makes the installation and disassembly of filter device still not convenient enough, the improvement of sealing performance also fails to achieve the ideal state, and the design of flow guide structure still needs further optimization to realize more uniform airflow distribution.
