Title (EN) SCR MIXER AND SCR DEVICE COMPRISING SAME
(FR) MÉLANGEUR SCR ET DISPOSITIF SCR LE COMPRENANT
(KO) SCR 믹서 및 이를 포함하는 SCR 장치
Abstract: front page image
(EN)The present invention relates to an SCR mixer for mixing exhaust gas, and an SCR device comprising the same and, more specifically, to a mixing device for an exhaust gas post-treatment system of a diesel engine, the mixing device being for removing, by means of a catalyst and a filter, nitrogen oxide and diesel particulate matter contained in the exhaust gas to be discharged from an engine. According to the present invention, since a reducing agent is sprayed at an inner shell heated by exhaust gas, thereby increasing atomization and evaporation of reducing agent droplets, the SCR mixer has an effect of minimizing a phenomenon, occurring in a conventional mixer, in which a reducing agent is precipitated and sticks to the inner surface of an inner shell.
(FR)La présente invention concerne un mélangeur SCR pour mélanger des gaz d'échappement, et un dispositif SCR le comprenant. Plus spécifiquement, l'invention porte sur un dispositif de mélange pour un système de post-traitement des gaz d'échappement d'un moteur diesel. Le dispositif de mélange est destiné à éliminer, au moyen d'un catalyseur et d'un filtre, l'oxyde d'azote et la matière particulaire diesel contenue dans le gaz d'échappement devant être évacué d'un moteur. Selon la présente invention, le fait qu'un agent réducteur soit pulvérisé sur une enveloppe interne chauffée par les gaz d'échappement permet d'augmenter l'atomisation et l'évaporation des gouttelettes d'agent réducteur. Ainsi le mélangeur SCR a pour effet de minimiser le phénomène se produisant dans un mélangeur classique, et selon lequel l'agent réducteur est précipité et colle à la surface interne de la coque interne.
(KO)본 발명은 배기가스를 믹싱하는 SCR 믹서 및 이를 포함하는 SCR 장치에 관한 것으로, 더욱 상세하게는 엔진으로부터 배출되는 배기가스에 촉매와 필터를 이용하여 배기가스에 포함된 질소산화물과 디젤 입자상 물질이 제거되도록 하는 디젤 엔진의 배기가스 후처리 시스템용 믹싱 장치에 관한 것이다. 본 발명에 따른 SCR 믹서는 배기가스에 의해 가열된 이너쉘에 환원제가 분사되어 환원제 액적의 미립화 및 증발을 증가시켜 기존 믹서에서 발생되던 환원제가 이너쉘 내면에 석출되어 달라붙는 현상을 최소화하는 효과가 있다.
