Скачать или смотреть Why is pre-treatment of compressed air necessary?

In the carbon monoxide catalytic purification system, pre-treatment of the compressed air is the core prerequisite for ensuring the efficient operation and prolonging the lifespan of the catalyst. The air without pre-treatment contains oils, water vapor, particles and other chemical pollutants, which pose a fatal threat to the delicate catalyst.
Oil contamination will cover the active sites of the catalyst, causing irreversible "poisoning"; water vapor will inhibit the reaction efficiency and damage the catalyst structure; particulate matter will clog the bed layer and increase the pressure drop. Therefore, the pretreatment unit (including precision filtration, deep drying and activated carbon adsorption) is like an indispensable "purification line of defense", responsible for removing all these harmful substances to ensure that the air entering the catalytic device is clean and dry. This is not only about improving efficiency, but also the cornerstone for maintaining the reliability of the entire breathing air safety system. Any negligence may directly lead to the failure of the catalyst and endanger the life of the user.
