Abstract
The present application discloses an exhaust gas after-treatment mixing device including a first plate, a second plate and a mixer. The mixer includes a first space, a second space and a third space located between the first space and the second space. Top portions of the first space and the second space are in communication with the third space. The mixer includes a first raised portion protruding into the third space and a second raised portion located below the first raised portion. A fourth space is formed between the first raised portion and the second raised portion. As a result, the distance and time of urea evaporation is increased and the mixing uniformity is improved. Besides, a package with the exhaust gas after-treatment mixing device is also provided.
