Abstract

The invention discloses a tail gas aftertreatment package. The tail gas aftertreatment package includes a first shell, a first carrier, a second shell, a second carrier, and a mixing assembly, and the tail gas aftertreatment package further comprises a third carrier assembly detachably installed in the first shell in the axis direction of the first shell; the third carrier assembly includes a third shell, a third carrier, and a first mixer located at the downstream of the third carrier; the first mixer is provided with a first spiral sheet; and the mixing assembly is provided with a second mixer, and the second mixer is provided with a second spiral sheet. Compared with the prior art, by arranging the first mixer and the second mixer, the mixing uniformity of tail gas and urea liquid drops is improved; and in addition, by arranging the third carrier assembly detachably installed in the first shell in the axis direction of the first shell, the disassembly convenience of the third carrier assembly is improved.

Description

Technical field[0001]The present invention relates to an exhaust gas treatment package, which belongs to the field of engine exhaust gas treatment technology.Background technique[0002]The existing exhaust rear treatment packages typically include diesel oxidation catalysts, diesel particulate trays, and selective catalytic reductants, and the like. With the continuous upgrade of emission regulations, diesel particles capture need to clean up after a certain time, otherwise it is easy to cause system back pressure to increase, increase fuel consumption.Inventive content[0003]It is an object of the present invention to provide a mixture of a mixed effect and an exhaust gas rear treatment package for easy disassembly.[0004]In order to achieve the above object, the present invention adopts the following technical scheme: an exhaust gas post-processing package comprising a first housing, a first carrier in the first housing, a first housing parallel arrangement The second housing is pack...
