Do not stop spinning, capture oil smoke and oil smoke is not allowed to flee from pipeline.After attraction and centrifugal force remove, the secondary of spinning is not stopped
The oil smoke for being vortexed and high tangential motion being carried out in tube wall can be collected because gravity flows downward to oil collector sump tank 22 along inner tubal wall.
Layer 6 detaches, and disturbing flow device 111 detaches：The disturbing flow device 111 of 11 one end of concentric tube generates remaining oil smoke
Flow field separation occurs, is detached by flow field, part oil smoke because stopping during the unstability in flow field not toward flowing in length and spin
The vortex turned captures oil smoke.
Layer 7 detaches, wind wheel centrifugal force separate：After the first six layer separation, it is left a small amount of very light soot particles
The wind wheel of exhausting component 4 is sucked due to pressure differential, the wind wheel of rotation forms centrifugal force and remaining a small amount of soot particles are thrown to wind
On the inner wall of machine, last almost clean gas is discharged external through gas outlet.
