Now by vent gas treatment to the discharge standard for meeting Europe six.
Therefore, how to reduce the low temperature crystallization of urea and ammonia is uniformly taken to SCR carriers end face to as in SCR technology
Key link, and at present existing structure exist urea be easy crystallization and ammonia mixing it is uneven the problems such as.
Invention content
The purpose of this utility model be for existing SCR technology there are the problem of, a kind of swirl vane and clam shell collection are provided
At mixing arrangement, which, by using swirl vane structure, is that cyclone pipe internal gas flow is fully rotatable, rear end passes through freshwater mussel
Shell structure plays guiding air-flow, and urea granules is made more to be evenly distributed on the end faces SCR, solves existing SCR technology and deposits
The problem of.
For the above technical purpose of realization, the technical solution adopted in the utility model is：A kind of swirl vane is integrated with clam shell
Mixing arrangement, including urea nozzle, injection pedestal, cyclone pipe, cylinder, partition board and clam shell, which is characterized in that the cylinder lateral wall
Injection pedestal is connected on the boss of top, the urea nozzle is mounted on injection pedestal, below the inner barrel boss
Equipped with cyclone pipe, there is the nozzle of beveling in the upper end of the cyclone pipe, and the nozzle is parallel with the table top of boss, under the cyclone pipe
End is connected with clam shell, is separated by partition among the cylinder, the clam shell break-through partition board.
Further, the cyclone pipe includes the swirl vane of multi-disc extrapolation, and the nozzle and cylinder boss of upper end beveling
Table top is at a distance of 4mm ~ 6mm.
Further, the cyclone pipe be rolled by stainless steel plate bar stock cutting by punching and connected it is molding.
Further, the clam shell is connected by upper clam shell with lower clam shell molding, and the shell wall of lower clam shell is equipped with multiple
Aperture.
Further, the partition board is equipped with aperture, and the aperture is located at below clam shell.
Further, the center line of the urea nozzle is overlapped with the center line of cyclone pipe.
From the above, it can be seen that the utility model has technical effect that：
1）The utility model uses swirl vane structure, so that cyclone pipe internal gas flow is fully rotatable, urea liquid flows into
Inside cyclone pipe, the eddy flow effect that blade is formed makes urea liquid be sufficiently mixed, good mixing effect；
2）The stream blade rear end of the device cyclone pipe uses clam shell design, on the one hand can increase mixing distance, another party
Face can utilize the guide profile air-flow of clam shell, and urea granules is enable more to be evenly distributed on the end faces SCR；
3）The direction of the urea nozzle setting of the device is leaned forward, and making the urea liquid ejected, there are one past
The speed that SCR is walked end face makes urea liquid be easier to be entrained by the flow of air, and reduces the risk of urea crystals.

Specific implementation mode
With reference to specific drawings and examples, the utility model is described in further detail.
With reference to the accompanying drawings shown in 1 ~ 3, a kind of swirl vane integrates mixing arrangement, including urea nozzle 1, injection pedestal with clam shell
2, cyclone pipe 3, cylinder 4, partition board 5 and clam shell 6, which is characterized in that injection bottom is connected on the boss above 4 side wall of the cylinder
Seat 2, the urea nozzle 1 are screwed on injection pedestal 2, and cyclone pipe 3 is equipped with below 4 internal boss of the cylinder,
There is the nozzle of beveling in the upper end of the cyclone pipe 3, and the nozzle is parallel with the table top of boss, and 3 lower end of the cyclone pipe is connected with
Clam shell 6 is separated among the cylinder 4,6 break-through partition board 5 of the clam shell by partition board 5.
The cyclone pipe 3 includes the swirl vane 31 of multi-disc extrapolation, and the nozzle and 4 boss surface phase of cylinder of upper end beveling
Away from about 5mm, the cyclone pipe 3 be rolled by stainless steel plate bar stock cutting by punching and connected it is molding, the clam shell 6 by upper clam shell and under
