The position intersected of adjacent two lines section position 15 occurs for vortex.The effect of 11 shape of concentric tube of the present invention is that oil can be made
Flue gas body generates vortex in 11 inner wall of concentric tube, improves the efficiency of removing oil smoke.
The diameter of one end of concentric tube 11 is more than the diameter of the other end.One end of concentric tube 11 is what is connect with exhausting component
One end, as 11 gas outlet of concentric tube, the other end of concentric tube 11 are the air inlet of concentric tube 11, can according to Venturi effect
Know, the bigger flow velocity of the area that fluid flows through is smaller, i.e., the speed of one end of gas concentric pipe 11 is more than the other end of concentric tube 11
Speed.According to Bernoulli's theorem, it is found that the speed of gas is got over, high pressure is smaller again, therefore concentric tube 11 is connect with exhausting component

Piece 22 can also be fixedly installed in shell, depending on specific embodiment is with performance.The shell 2 of the present invention is spherical housing
2
The effect of annular lamina 22 is that soot gas is made to generate vortex, while prevent soot particles from throwing away again when entering shell 2
During oil fume separator 1 exterior space is thrown away from the housing inlet 2 of shell 2.
The operation principle of the kitchen ventilator is：Kitchen ventilator is opened, electric rotating machine 4 drives oil fume separator 1, the wind of exhausting component
Wheel rotates simultaneously, and soot particles are by seven layer separations inside kitchen ventilator, and most almost the gas of cleaning is arranged again through gas outlet finally
Go out.This seven layer separation is specific as follows：
First layer separation, inertial separation：Oil smoke enters via the housing inlet 2 of shell 2 inside smoke machine, and oil smoke enters outer
Enter annular lamina 22 after shell air inlet 2, because rapid with 2 area of pressure differential and housing inlet of external environment inside shell 2
Become, air velocity can be accelerated, and moment of inertia also relatively increases.And oil smoke can form very thin boundary around annular lamina 22
Layer, but because the housing inlet 2 and annular lamina 22 of shell 2 are in angle, after oil smoke is forced to flow downward along annular lamina 22
Oil fume separator 1 is up flowed into, therefore heavier oil is separated with crude oil plume field in downward inertia motion and transported down
The dynamic oil collector sump tank 3 collected in 2 bottom of shell, realizes first time inertial separation.
Second layer separation, cyclonic separation：Soot particles by the first layer separation are in the direction of annular lamina 22 by lower turn
Flowing in further occur flow field separation, soot particles flow field detach under cause unsteady flow field, be further formed vortex.
Flow field or vortex can interact influence with neighbouring flow field or vortex, and the flow field for not stopping spinning is formed in annular lamina 22, this
When rotating vortex reach maximum vorticity.The lighter oil smoke of remaining part can not be parked in the rotating vortex accumulation of annular lamina 22, when
When running up to constant weight, flow field branch is unable to hold out the weight of oil droplet, will fall downwards or flow to oil collector sump tank along annular lamina 22
3。
Third layer separation, centrifugal force separate：Eaves portion structure 13 follows the rotation of concentric tube 11 to form centrifugal force, centrifugal force and wind
The attraction interaction of wheel.After second detaches, the lighter oil smoke of remaining part is first contacted when entering concentric tube 11
Outermost end to eaves portion structure 13 enters back into concentric tube 11, and the centrifugal force of 13 outermost end of eaves portion structure can be segment fluid flow or oil
Smoke particle is taken away or stops into 11 inside of concentric tube and move outward, then thrown away with higher tangential velocity, is thrown out of particle
It can fall in annular lamina 22, oil collector sump tank 3 is flow to finally along annular lamina 22.
4th layer separation, inertial separation and centrifugal force separate：After third layer separation, the oil smoke of remaining lighter weight is same
When acted on by centrifugal force and attraction, but opposite attraction is more than centrifugal force.A portion of these oil smoke can be through
It crosses through-hole 131 to flow to adjacent eaves portion structure 13, because effect of inertia and other oil smoke or soot particles pool larger oil
Smoke particle flow down, but because centrifugal force acts on, soot particles are simultaneously flowed with being thrown away compared with high tangential velocity finally along annular lamina 22
Move oil collector sump tank 3.
Layer 5 detaches, the cyclone centrifugal force of concentric tube 11 and the secondary generation that is vortexed：11 inner wall of concentric tube rotates to form gas
Rotation, concentric tube 11 be low-pressure area under the action of the centrifugal force, fluids within pipes or particle etc. are moved toward duct wall, and tube wall forms height
Tangential velocity, part oil smoke are blocked flowing up.It is vortexed, does not stop in addition, remaining oil smoke can be formed in vortex generator
Spinning captures oil smoke and oil smoke is not allowed to flee from pipeline.After attraction and centrifugal force remove, do not stop spinning secondary vortex flow and
The oil smoke that high tangential motion is carried out in tube wall can be collected because gravity flows downward to oil collector sump tank 3 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, be left a small amount of very light soot particles because
Pressure differential and the wind wheel for sucking exhausting component, the wind wheel of rotation form centrifugal force and remaining a small amount of soot particles are thrown to wind turbine
On inner wall, last almost clean gas is discharged external through gas outlet.
The kitchen ventilator with rotatable oil fume separator generates additional centrifugal force separate oil smoke, while electric rotating machine 4
In the surface of energy oil fume separator 1, stability when oil fume separator 1 rotates is improved.The maximum width of electric rotating machine 4 is small
It can ensure that soot gas smoothly enters exhausting component in the gas outlet maximum width of oil fume separator 1.This is with rotatable oil smoke
