Description
рующнй клапан 9, измен ющий расход воды, гюступающсн в смеситель 13, где она, соедин сь со свободным серным ангидридом, превращаетс в кнслоту и уменьщает или увеличивает пронентное содержание серного ангидрида в олеуме.The pilot valve 9, which changes the flow rate of water, is pushed into the mixer 13, where it, when combined with free sulfuric anhydride, is converted into a slot and reduces or increases the permeable content of sulfuric anhydride in oleum.
