Embodiment Construction
[0028] Such as Figure 1-4 As shown, the present invention includes an air inlet chamber 1 and an air outlet chamber 2 that is rotatably connected and communicated with the air inlet chamber 1. The position between the air inlet chamber 1 and the air outlet chamber 2 can be set arbitrarily. 2 can be arranged horizontally, vertically or obliquely. In this embodiment, the air inlet cavity 1 and the air outlet cavity 2 are distributed up and down.
[0029] The air intake chamber 1 and the air outlet chamber 2 are respectively provided with an air inlet deflector 4 and an air outlet deflector 5; The deflector 4 , the space between the intake chamber body and the intake deflector 4 forms a cavity structure for the exhaust gas and urea to fully mix. The air outlet chamber 2 includes an air outlet chamber body and an air outlet deflector 5 covered on the air outlet chamber body, and the space between the air outlet chamber body and the air outlet deflector 5 forms a cavity structur...
