Document Type and Number:
WIPO Patent Application WO/2016/134647
Kind Code:
A1
Abstract:
Disclosed is a mixing pipe (24) for use in an exhaust treatment device (100) of an engine, which comprises a first semicircular pipe (241) and a second semicircular pipe (242) matching each other, wherein the first semicircular pipe and the second semicircular pipe are offset from each other in a radial direction to circumferentially form a first outlet (243) and a second outlet (244), and the opening direction of the first outlet is opposite to that of the second outlet so as to form a rotational flow. The mixing pipe has a simple structure, and the rotational flow can also rotate after entering into a mixing space, which increases the stroke of a gas flow in a limited space so as to increase the distance of the evaporation of urea liquid drops, and increases the evaporation rate and the homogeneity of the mixing. Further disclosed is an exhaust treatment device with the mixing pipe.
