Description
Technical field
The present invention devises a kind of diesel vehicle carbamide Double helix binary vortices SCR blender, and it can be applied and locate after aerofluxus
In reason device urea SCR.
Background technology
At present, along with the country's increasingly attention to environmental law, emission of diesel engine regulation state four, the progressively enforcement of state five,
Trap-oxidizer uses carbamide to reduce NOXIncreasingly come into one's own, and hydrolysis of urea becomes ability and NO after ammoniaXReact,
The hydrolysis of carbamide is presently mainly and is realized by blender, but the blender used at present easily produces greater back-pressure, impact
Engine power；And it is insufficient to hydrolysis of urea；Can not effectively reduce NOX, and easily just give birth to crystalline polamer.
Summary of the invention
For problems of the prior art, it is an object of the invention to overcome above-mentioned blender operation not enough,
Solving back pressure big, joint gathers compact lower layout, hydrolyzes the defects such as insufficient.The present invention provides a kind of for emission aftertreatment carbamide
The blender of atomization, a kind of diesel vehicle carbamide Double helix binary vortices SCR blender makes hydrolysis of urea complete, it is not easy to crystallization, quilt
Forcing down, joint gathers compact；It can be widely applied to preprocessor and uses carbamide to reduce tail gas NOX。
In order to reach foregoing invention purpose, the technical solution used in the present invention is: the double whirlpool of a kind of diesel vehicle carbamide Double helix
Rotation SCR blender；Main by two groups of integral type blades, form several groups of passages so that air-flow forms two groups of double whirlpools in passage
Rotation so that carbamide atomization is uniformly；Using advanced binary vortices structure, last binary vortices sprays in different angles, impinges upon together,
Make carbamide atomization uniformly；It is characterized in that: it includes cylinder 1, lead 11, end cap 2, front helical blade 6, rear screw blade
10, front apron 5, urea nozzle 8, distributing damper 16；Described front helical blade 6, rear screw blade 10 install described lead 11
On；Described cylinder 1, front apron 5, front helical blade 6, end cap 2 form unidirectional main channel；Described distributing damper 16 is installed on described
Between front helical blade 6, rear screw blade 10；Described urea nozzle 8 is arranged on unidirectional main channel.
The present invention uses front helical blade 6, rear screw blade 10 to be the spiral-shaped blade constructions of integral type, and helical blade belongs to
In cold extrusion shaped or punch forming；The helical blade number of turns is in 0.5-3 encloses；And punching or punching are different in nature on helical blade
Groove structure；Front helical blade 6, rear screw blade 10 are welded on lead 11 by certain angle, and spacing is the 1/2 of pitch.
According to the present invention, front helical blade, rear screw blade, when enclosing with 0.5-1, can use punching type spline structure；Adopt
By turnup structure, internal punching or opposite sex groove structure.
According to the present invention, current helical blade, rear screw blade are when enclosing with 0.5-1, and flanging welded is above cylinder.
According to the present invention, the two ends of described front apron 5 are installed between described front helical blade 6, end cap 2, have peace
It is loaded on described lead 11.
According to the present invention, front apron welds with helical blade, drive end bearing bracket, lead；Nozzle base is on cylinder, before being positioned at
Between helical blade and end cap；Nozzle impinges upon on front helical blade with ejection carbamide.
According to the present invention, distributing damper is installed between front helical blade, rear screw blade；Aperture or abnormal shape are opened in centre
Hole.
According to the present invention, being additionally provided with dividing plate blender 12 and little blanking cover 15, described dividing plate blender 12 is installed on cylinder 1
In, described little blanking cover 15 is installed on described lead 11 end.
Beneficial effect: in due to the fact that helical blade and the same cylinder of carrier, air-flow is big by sectional area, and back pressure is relatively
Low；Being threadingly advanced owing to air-flow uses, constantly clash into helical blade along journey carbamide, carbamide is easier to hydrolysis, and last air-flow passes through
Being divided into two strands of flow spirals to advance, last two strands of spiral air flows impinge upon together, and carbamide is easier to atomization, and ammonia mixes with waste gas
Evenly；Two strands of spiral air flows hit after clashing into on cylinder, reflecting helix air-flow, advance through dividing plate blender uniformly, then
Secondary hydrolysis atomization.

Detailed description of the invention
The detailed description preferred forms of the present invention made below in conjunction with specific embodiments and the drawings: such as: air-flow
Cross the flow direction of each passage, and injection carbamide how inside blender the operation principle such as atomization elaborate.
The diesel vehicle carbamide Double helix binary vortices SCR blender of the embodiment of the present invention, by 2 groups of helical blades, air-flow elder generation warp
Crossing principal screw passage, then air-flow is divided into two groups, mixes and pass through in two groups of helical blades, forms two groups of binary vortices air-flows；Two
Together, carbamide crushes stock airflow strikes further, and hydrolysis hydrolyzes finally by impinging upon cylinder, atomization, shape further above
Become ammonia so that waste gas is homogenously mixed together with ammonia；Owing to Double helix binary vortices SCR blender is placed inside cylinder, the back of the body
Pressing the least, spaces compact, carbamide atomization is uniformly；Solve by the contradiction of pressure with carbamide atomization；Solve the structure of tight space
Carbamide fogging problem.As shown in Figure 1, 2: its architectural feature is, it includes cylinder 1, lead 11, end cap 2, front helical blade 6
The composition unidirectional main channel of prime 100, there is urea nozzle 8 unidirectional main channel 100, and urea liquid injects directly on unidirectional main channel
In 100；Front helical blade 6, lead 11, rear screw blade 10, front apron 5, distributing damper 16 form two strands of gas channels；Before
Helical blade 6 and rear screw blade 10 are divided into two runners.Carbamide Double helix binary vortices SCR blender: urea nozzle 8 is installed on
Injection base 9, injection pedestal 7 and nozzle base 9 are positioned at upper end, unidirectional main channel 100, after injection carbamide, in unidirectional main channel
In 100, waste gas drives carbamide to be threadingly advanced；Major part carbamide clashes into front helical blade 6, owing to having aperture on front helical blade 6,
Part mixed airflow is directly entered the 3rd gas channel 300；Major part air-flow is threadingly advanced along main channel, is then divided into two
Point, it being partly into the second gas channel 200, air-flow forms eddy current in passage；It is partly into the 3rd gas channel 300,
Air-flow forms eddy current in passage, with the collision that early stage direct part mixed airflow is directly entered the 3rd gas channel 300, merges
For one, last two strands of spiral air flows mutually clash into, and then clash into on cylinder 1, pass through dividing plate blender 12 the most uniformly.
The diesel vehicle carbamide Double helix binary vortices SCR blender of the present embodiment, air inlet pipe 3 is connected with inlet flange 4；Carrier
13 and liner 14 be located in cylinder 1, little blanking cover 15 is installed on lead 11 end；16 is distributing damper.
Fig. 3-8 is the front helical blade of the embodiment of the present invention, rear screw blade construction figure and constitutional diagram.
Use technical scheme: make carbamide atomization more thorough, mix with tail gas more uniform；Use advanced person
Twin scroll technology, last binary vortices sprays in different angles, impinges upon together so that carbamide atomization is uniformly；Can significantly carry
Rise SCR conversion efficiency；Substantially urea crystals phenomenon is stopped；Structure is extremely compact, and back pressure is low, after can be widely applied to diesel vehicle
Processing system.
Above example is described only for the partial function of the present invention, but embodiment and accompanying drawing are not for limiting
Determine the present invention's.Any equivalence change done in the spirit and scope without departing from present invention application or retouching, also belong to
