Description
Technical field
The present invention relates to a kind of axial-flow type rotating vane mixing arrangements for vent gas treatment, and in particular to one kind is used for vapour
The axial-flow type rotating vane mixing arrangement of tailstock gas disposal, belongs to tail gas clean-up technical field.
Background technology
Implementing in full for the state four standard discharged with China about restricting vehicle exhaust pollutant, utilizes exhaust aftertreatment
System reduces engine exhaust nuisance, it has also become the inevitable choices of engine works.The design of inlet chamber is post-processed to carrier
Catalytic conversion efficiency have a major impact.It is limited by plan boundary, the design space of inlet chamber often very little is left for, it is difficult to protect
Card air-flow is sufficiently mixed in inlet chamber, this results in air-flow to be unevenly distributed in carrier front end face, in turn results in regional area gas
Flow velocity degree and temperature are higher, make the region quick aging, and other regions are not fully utilized, and have both reduced turning for carrier
Change efficiency reduces the service life of catalyst converter again.
Invention content
The purpose of the present invention is overcoming the deficiencies in the prior art, a kind of axial-flow type for exhaust aftertreatment is provided
Rotating vane mixing arrangement, the mixing arrangement can make gas mixing more abundant, reduce mixing distance, and it is empty to save mixing
Between.
Technical scheme of the present invention, for the axial-flow type rotating vane mixing arrangement of vent gas treatment, including admission line, into
Gas end cap, catalyst housing, rear end cap and outlet pipe；The admission line is connect with air inlet end cap, air inlet end cap and catalysis
Agent housing connects, and catalyst housing is connect with rear end cap, and rear end cap is connect with outlet pipe.
Further include liner and catalyst carrier；The catalyst housing is internally provided with catalyst carrier, catalyst housing and
Liner is equipped between catalyst carrier.
Mixing arrangement is further included, the admission line Inner Front End is fixedly connected with mixing arrangement.
The blade of mixing arrangement four torsions evenly distributed in the circumferential direction, the windup-degree of blade is 45-55 °,
The width of blade is 1-2mm, and the height of blade is 15-30mm.
The windup-degree of blade is 47.8 ° in the mixing arrangement, and the width of blade is 1.8mm, and the height of blade is
21mm。
Beneficial effects of the present invention：The present invention is compact-sized, and engine exhaust is made to enter under the action of mixing arrangement
It is sufficiently mixed before air inlet end cap, improves flow uniformity, catalytic conversion efficiency and the service life of carrier, while it is empty to save design
Between, it can reach state five and above discharge standard.

Specific embodiment
As shown in Figs. 1-3, for the axial-flow type rotating vane mixing arrangement of vent gas treatment, including admission line 2, inlet end
Lid 3, catalyst housing 4, rear end cap 7 and outlet pipe 8；The admission line 2 is connect with air inlet end cap 3, and air inlet end cap 3 is with urging
Agent housing 4 connects, and catalyst housing 4 is connect with rear end cap 7, and rear end cap 7 is connect with outlet pipe 8.
Further include liner 5 and catalyst carrier 6；The catalyst housing 4 is internally provided with catalyst carrier 6, catalyst shell
Liner 5 is equipped between body 4 and catalyst carrier 6.
Mixing arrangement 1 is further included, 2 Inner Front End of admission line is fixedly connected with mixing arrangement 1.
The blade of 1 evenly distributed in the circumferential direction four torsion of mixing arrangement, the windup-degree of blade is 45-55 °,
