The other end of the duct 130 is disposed in the air outlet 114 of the first wall 102 to close the air outlet 114. The duct outlet 131 opens onto the wall of the duct 130. The gas flow channel 115 is formed circumferentially around the duct 130 so that gas entering from the first region 1121 to the second region 1122 must pass through the gas flow channel 115 and then be discharged from the duct outlet 131.

By connecting one end of the duct 130 to the second wall 103 and disposing the other end of the duct in the air outlet 114 of the first wall 102, one end of the duct 130 is blocked by the second wall 103, and the air in the second cavity 112 can only be discharged from the predetermined duct outlet 131. The outlet 131 of the duct may be selectively disposed in the second region 1122 according to a predetermined gas moving path, so as to prolong the mixing time of the gas in the second chamber 112, thereby improving the reaction efficiency of the subsequent reaction.

Further, in the illustrated embodiment, the duct outlet 131 is disposed on a wall of the duct 130, and one side of the duct outlet is connected to the air outlet 114, and the other side of the duct outlet is connected to the second wall 103.

Further optionally, a plurality of apertures 125 are provided in the first wall 102. Further optionally, the plurality of apertures 125 are evenly distributed within the airflow channel 115.

The structure of the airflow channel 115 makes it easy to form a large vortex inside the airflow, thereby enhancing the mixing effect of the ammonia gas and the tail gas. However, large vortices also cause non-uniformity in the flow and areas of lower flow velocity occur. By arranging the small holes 125, the vortex degree of the air flow can be reduced, and the uniformity of the air flow is improved, so that the uniformity of the air flow is ensured when the air flow subsequently enters the air inlet end surface of the SCR catalyst. Further, one side of the drainage plate 140 is connected to the first wall 102, the other side is connected to the second wall 103, and one end of the drainage plate 140 is connected to the pipe wall of the pipe 130 and is close to the pipe outlet 131.

By connecting one side of the flow guide plate 140 to the first wall 102 and the other side to the second wall 103, the second cavity 112 can be divided into a first region 1121 and a second region 1122, so that the gas is ensured to pass through the first region 1121, then pass through the second region 1122 and finally be discharged from the pipe outlet 131 of the second region 1122 after entering the second cavity 112.

In the illustrated embodiment, the flow guide plate 140 has one end in communication with the inner wall of the duct outlet 131 and the other end facing the first end 123 of the partition 120, thereby dividing the second chamber 112 into a first broader region 1121 and a second narrower region 1122. The tail gas and ammonia gas enter the narrow second region 1122 from the wide first region 1121, so that a large vortex can be generated, the mixing effect is greatly improved, and the gas is fully mixed.

In other alternative embodiments of the present application, one end of the drainage plate 140 is in communication with the inner wall of the tube outlet 131, and the other end is also connected to the first end 123 of the partition 120, or to the inner wall of the second chamber 112 on the corresponding side.

Further, in some embodiments of the present application, a flow guide tube 150 is disposed within the first cavity 111.

Specifically, the flow guide pipe 150 is used in combination with the partition plate 120 to guide the urea injection, so as to prevent the urea from directly impacting the inner wall surface of the first cavity 111 when the exhaust gas flow enters the first cavity 111, thereby reducing the possibility that the urea is easily crystallized. Further, through setting up honeycomb duct 150 for the air current that gets into honeycomb duct 150 becomes high-speed air current, and high-speed air current can carry out once breakage to urea, thereby improves urea evaporation effect.

Further, the outlet end of the draft tube 150 is connected to the partition 120, and the inlet end of the draft tube 150 extends to the inlet hole 101.

By connecting the outlet end of the flow guide pipe 150 to the partition plate 120, the inlet end extends to the inlet hole 101, so that urea entering the first cavity 111 from the inlet hole 101 can directly reach the partition plate 120 along the flow guide pipe 150, and is prevented from being sprayed onto the inner wall of the first cavity 111 when being sprayed, and crystallization is prevented from being formed.

Furthermore, a gap 151 is opened on the wall of the draft tube 150.

The gap 151 is formed in the wall body of the draft tube 150, so that heat of tail gas entering the first cavity 111 from the air inlet 113 of the first cavity 111 can enter the draft tube 150, and urea inside the draft tube 150 is subjected to thermal decomposition.

In the illustrated embodiment, two notches 151 are formed on the wall of the duct 150, and are respectively disposed on a side facing the air inlet 113 of the first chamber 111.

The shape of the first through-hole 121 is different from the shape of the second through-hole 122. Illustratively, the first through-holes 121 include a plurality of rectangular holes spaced apart from each other, and the plurality of rectangular holes are sequentially disposed at both ends of the partition plate 120 in a length direction of the partition plate 120. The second through hole 122 includes a plurality of square holes connected together to form a mesh shape. And a plurality of second through holes 122 are provided at the middle position of the partition plate 120 (the position between the first through holes 121 at both ends).

Further optionally, the hybrid spoiler 100 further includes baffles 116, one baffle 116 is connected to an inner wall of each first through hole 121, and a free end of each baffle 116 faces the second through hole 122.

The baffle 116 is connected to the inner wall of each first through hole 121, and the free end of the baffle 116 faces the second through hole 122, so that the tail gas entering the second cavity 112 is discharged from each first through hole 121 and can move towards the second through hole 122, and the tail gas is mixed with the ammonia gas discharged from the second through hole 122, thereby further improving the mixing uniformity.

In the illustrated embodiment, the free ends of the baffle plates 116 in the first through holes 121 at both ends of the partition plate 120 are oriented in the direction of the second through holes 122 at the middle of the partition plate 120. Further optionally, the baffle 116 is also connected to the inner wall of each second through hole 122, and the free ends of the baffles 116 at this position are not oriented exactly the same, that is, a part of the baffles in the second through holes 122 are oriented in one direction, and another part of the baffles in the second through holes 122 are oriented in another direction, so that the flow direction of the ammonia gas discharged from the second through holes 122 is disturbed, and the ammonia gas is further mixed with the exhaust gas better, and the uniformity of mixing is improved.

Further, the partition 120 is provided with an evaporator 160, and the evaporator 160 is disposed in the outlet end of the draft tube 150.

By providing the evaporator 160 in the outlet end of the draft tube 150, the urea entering the draft tube 150 can be broken and evaporated strongly, which is beneficial to the decomposition of the urea. Specifically, after urea is sprayed into the flow guide pipe 150, urea droplets contact with the evaporator 160, and the dual structure of the flow guide pipe 150 and the evaporator 160 strongly breaks and evaporates the urea droplets, so that the urea droplets are finer, and the subsequent urea decomposition reaction is facilitated.

Further, the evaporator 160 has a plurality of through holes connected in a grid, and the through holes are in one-to-one correspondence with the plurality of second through holes 122.

The through holes of the evaporator 160 are in one-to-one correspondence with the plurality of second through holes 122, so that the ammonia gas decomposed in the draft tube 150 can enter the second chamber 112.

And the device can mutually support with the baffle through setting up the honeycomb duct, plays the effect of water conservancy diversion to the urea of spouting, prevents that the air current from directly impacting the inner wall of first cavity with urea when through, is difficult to form the crystallization. Further, under the dual function of honeycomb duct rather than inside evaporimeter, can carry out powerful broken evaporation to the urea liquid drop for the urea liquid drop is more tiny, is favorable to the decomposition reaction of follow-up urea, makes the decomposition of urea more fully. Further, the flow guide plate is combined with the pipeline to form an airflow channel in the second chamber, so that the path for mixing ammonia gas and tail gas is increased, the mixing time is prolonged, airflow vortexes can be formed, and the mixing effect is greatly improved. So that the subsequent reaction efficiency of the mixed gas and the SCR catalyst is higher. The tail gas treated by the mixing and disturbing device 100 can meet the national six standards.
