Background
Studies have shown that the degree of uniformity of ammonia distribution in the lines of an exhaust aftertreatment system (e.g., a selective catalytic reduction system, SCR system) has a significant impact on the overall performance and durability of the system. If ammonia (NH)3) Uneven distribution can result in inefficient nitrogen oxide (NOx) conversion and can be prone to ammonia slip contamination if urea injection is increased to meet emissions performance. Meanwhile, urea liquid drops are easy to deposit when contacting with a wall surface with lower temperature, and the formed crystals can block an exhaust pipe when serious, so that the power performance of the engine is reduced. The urea utilization rate can be effectively improved by improving the mixing uniformity of ammonia molecules, and the urea injection amount is reduced, so that the risk of urea crystallization is reduced.
Therefore, it is necessary to provide a mixing assembly capable of improving the uniformity of ammonia molecule mixing to solve the above technical problems.

Detailed Description
Referring to fig. 1-10, a hybrid assembly 100 for use in an engine exhaust aftertreatment device for treating an exhaust gas of an engine is disclosed. The exhaust aftertreatment device may include a first aftertreatment component (not shown) located upstream of the mixing assembly 100 and/or a second aftertreatment component (not shown) located downstream of the mixing assembly 100. Wherein the first aftertreatment component may be an oxidation catalyst (DOC) or a combination of a DOC and a diesel particulate trap (DPF) and the second aftertreatment component may be a Selective Catalytic Reduction (SCR). In addition, as can be understood by those skilled in the art, the DOC, the DPF, the SCR, and the like may be designed as other types of catalysts or combinations according to actual needs, and details are not described herein.
The mixing assembly 100 includes a housing 3, a first baffle 1 positioned within the housing 3, a second baffle 2 positioned within the housing 3, and a mixing element 4 at least partially bridging the first baffle 1. In the illustrated embodiment of the present invention, the housing 3 is cylindrical and is provided with an end cap 30, and the end cap 30 is provided with an arc-shaped inner surface 301. In addition, the housing 3 includes a first cavity 31 located at one side of the first diaphragm 1, a second cavity 32 located at the other side of the first diaphragm 1, and a third cavity 33 located downstream of the second cavity 32. In the illustrated embodiment of the invention, the first bulkhead 1 and the second bulkhead 2 are arranged at a distance, and the mixing element 4 is mounted on the first bulkhead 1 and the second bulkhead 2. The first cavity 31 is located between the first partition board 1 and the end cap 30, and the second cavity 32 is located between the first partition board 1 and the second partition board 2.
The first partition board 1 is provided with a plurality of first through holes 11 communicating the first cavity 31 and the second cavity 32. The first baffle plate 1 is also provided with a first cardioid groove 12 supporting the mixing element 4.
The second partition board 2 is provided with a plurality of second through holes 21 communicating the second cavity 32 and the third cavity 33. The second baffle plate is further provided with a second heart-shaped groove 22 supporting the mixing element 4, the first heart-shaped groove 12 being larger in size than the second heart-shaped groove 22.
The mixing element 4 is sealed at one end and open at the other. In the illustrated embodiment of the invention, the side of the mixing element 4 adjacent to the second partition 2 is sealed and the side of the mixing element 4 adjacent to the first partition 1 is open. The mixing element 4 is provided with an internal cavity 40 communicating with the first cavity 31. The mixing element 4 is provided with a protrusion 5 protruding into the inner cavity 40, and the cross-sectional area of the inner cavity 40 is tapered along the extension direction of the mixing element 4. In the illustrated embodiment of the invention, the mixing element 4 has a circular-arc-shaped top surface 41 and an inclined bottom surface 42. The protrusion 5 protrudes upward from the bottom surface 42, and the protrusion 5 extends integrally from one side of the mixing element 4 to the other side of the mixing element 4. In particular, the mixing element 4 is provided with a sealing end cap 43 manufactured separately from the mixing element 4 and fixed on one side of the mixing element 4.
The mixing assembly 100 is further provided with an inlet pipe 6 communicated with the internal cavity 40, the inlet pipe 6 is provided with a nozzle mounting portion 61 for mounting a urea nozzle (not shown) for spraying urea droplets into the internal cavity 40. In the illustrated embodiment of the invention, the inlet duct 6 is arranged vertically and substantially perpendicular to the top surface 41 of the mixing element 4. Referring to fig. 5 to 7, in the illustrated embodiment of the present invention, the inlet pipe 6 and the mixing element 4 are eccentrically disposed, that is, the axial center of the inlet pipe 6 is offset from the center of the mixing element 4. So arranged, the gas flow can be made to swirl better when entering the mixing element 4.
Referring to figure 10, shown by the solid arrows, in use, exhaust gas from the engine enters through the inlet pipe 6; when the injection condition is reached, the urea nozzle is used for injecting urea liquid drops into the internal cavity 40 so as to mix the urea liquid drops with the exhaust gas of the engine; the mixed air flow forms a double-swirl air flow mixing effect on both sides of the boss 5 (see hollow arrows in fig. 9); in addition, the inclined bottom surface 42 and the gradually changed sectional area of the inner cavity 40 guide the mixed gas flow, and the mixing effect is improved; as one side of the mixing element 4 is sealed by the end cap 43, the mixed gas flow moves towards the open end of the mixing element 4 and into the first cavity 31; the arc-shaped inner surface 301 of the end cover 30 can play a good role in reflecting the mixed air flow so as to promote the mixed air flow to enter the second cavity 32 through the first through hole 11; the mixed gas then passes through the second perforations 21 into the third chamber 33 and through a downstream second aftertreatment component to effect the cleaning of the exhaust gases of harmful species.
