Rotation, oil smoke enter multistage vortex oil-fume separating device 2 from air inlet, and soot particles pass through 4 layer separations inside kitchen ventilator, most
It is discharged again through gas outlet with almost clean gas eventually.This 4 layer separation is specific as follows：
1st layer separation, centrifugal force separate：Annular fan 21 rotates formation centrifugation with concentric tube 22 under the drive of rotary shaft 23
Power, the attraction that the rotation of exhausting component 3 generates.After second detaches, remaining part oil smoke, its own gravity and attraction
Quite, oil smoke first touches the outermost end of annular fan 21 when entering concentric tube 22, under the influence of centrifugal force, oil smoke fluid or
Person's soot particles are displaced outwardly along annular fan 21, are partly thrown away from the through-hole 211 on annular fan 21, partly with higher tangent line
Speed is directly thrown away.
2nd layer separation, inertial separation and centrifugal force separate：After the 1st layer separation, the oil smoke of remaining lighter weight is simultaneously
It is acted on by centrifugal force and attraction, but opposite attraction is more than centrifugal force.A portion of these oil smoke can pass through
211 upward single order annular fan 21 of through-hole flows, and because of effect of inertia, larger soot particles are difficult to flow up, and because of centrifugal force
Effect, soot particles compared with high tangential velocity to throw away.
3rd layer separation, the interior generation vortex of concentric tube 22：Concentric tube 22 rotates, and oil smoke fluid is in pressure differential and centrifugation masterpiece
Under, vortex is formed inside concentric tube 22, does not stop spinning, oil smoke is captured and heavier oil particles is not allowed to flee from pipeline, it is another
Part oil smoke is close to tube wall and is moved in high tangential velocity, is blocked flowing up.After attraction and centrifugal force remove, in pipeline
The soot particles that oil smoke fluid fell and be close to tube wall move under the effect of gravity along tube wall, realize cyclonic separation.
4th layer separation, 3 centrifugal force separate of wind wheel：After preceding 4 layer separation, be left a small amount of very light soot particles because
Pressure differential and suck wind wheel 3, the wind wheel 3 of rotation forms centrifugal force and remaining a small amount of soot particles is thrown on the inner wall of wind turbine,
Last almost clean gas is discharged external through gas outlet.
