Background technology
With the increasingly raising of living standard, automobile becomes increasingly popular, the tail gas of the automobile also arch-criminal as environmental pollution
One of, in order to reduce harm of the vehicle exhaust for environment, people increased catalytic unit in tail gas, by spray urea with
Tail gas mixes, by catalysis silencing apparatus, reducing harm of the tail gas to environment, but the urea of injection be difficult it is complete with tail gas
Mixing, causes the conversion performance of catalytic muffler to decline, and urea crystals are serious, prevent tail gas from being converted well, You Haiqi
Body pollutes environment in being directly discharged into air.
Utility model content
In order to overcome existing injection urea to be difficult to mix with tail gas, catalytic muffler conversion performance is caused to decline, this reality
With new there is provided a kind of device that tail gas can be made fully to mix with urea.
Technical problem to be solved in the utility model is realized using following technical scheme：
One kind solves vehicle exhaust and the well-mixed device of urea liquid, including air inlet adpting flange, inlet flange, mixed
Attach together put, hybrid chamber, nozzle mounting seat, exhaust adpting flange, described air inlet adpting flange one end connection mixing arrangement, mixing
The other end of device is connected by adpting flange with hybrid chamber, and there is a nozzle mounting seat hybrid chamber upper end, hybrid chamber it is another
End connection exhaust adpting flange；
The mixing arrangement is made up of shell, positive impeller blade, anti-impeller blade and plug, and the shell is cylindrical tube,
The positive impeller blade, anti-impeller blade and plug are arranged in shell, and the positive impeller blade, anti-impeller blade are separately mounted to plug
Two ends, the positive impeller blade, anti-impeller blade and plug are coaxial with shell；
The hybrid chamber is cylindrical tube, and hybrid chamber is coaxial docking with the shell；
The nozzle mounting seat has the injection channel connected with hybrid chamber, the axial direction of injection channel and the axial direction of hybrid chamber
With 30-45 ° of angle.
Preferably, the radial dimension of anti-impeller blade is more than the radial dimension of positive impeller blade, anti-leaf in the mixing arrangement
The radial dimension of piece and the minor diameter fit of shell are taken turns, positive impeller blade is coaxially connected by plug with anti-impeller blade, with identical
Rotating speed, different air draft speed, make gas reach the purpose of vortex mixing.
Preferably, the axial direction of the injection channel has 45 ° of angle with the axial direction of hybrid chamber.
Preferably, being provided with flange or installing plate for installing urea injection apparatus in the nozzle mounting seat.
