SCR SYSTEM USING REDUCTANT POWDER

摘要

The present invention relates to an SCR system using reductant powder which can increase space usage by being able to miniaturizing a device, and can increase exhaust gas treatment efficiency by being able to dissolve a reductant easily. The SCR system of the present invention includes: a storage tank (100) storing the reductant powder; an ejector (130) comprised to supply the reductant powder from the storage tank (100); and an eductor (150) which is comprised in a mixing unit (140) connected to a front of an SCR chamber (160) while an exhaust gas discharged from an engine passes through, so that the reductant powder supplied through the ejector (130) is dissolved and sprayed.
