Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a mixing device capable of atomizing a reducing agent sprayed from an addition valve and of introducing to an exhaust gas downstream side.

SOLUTION: A blade 31 constituting a mixing device is provided with a trapping part 40 for trapping an urea water in an exhaust flowing toward the exhaust downstream side from an exhaust upstream side along the surface 34 of the blade 31. The urea water trapped by the trapping part 40 is atomized through a slit 43 allowing a trapping space 41 and a space in the exhaust downstream side from the trapping part 40 to communicate with each other and is passed through the exhaust downstream side.

【課題】添加弁から噴霧された還元剤を微粒化して排気下流側に導くことができる混合装置を提供する。
【解決手段】混合装置を構成する羽根31には、該羽根31の表面34に沿って排気上流側から排気下流側に向けて流動する排気中の尿素水を捕捉する捕捉部40が設けられている。この捕捉部40に捕捉された尿素水は、捕捉空間41と捕捉部40よりも排気下流側の空間とを連通するスリット43を介して微粒化して排気下流側に通過する。
