Be the line segment that is made of the multistage broken line concentric tube 11 formed by the axis one week, 11 inner wall of concentric tube of concentric tube 11
Adjacent two lines section intersection position be vortex occur position 15, such as Fig. 6.The effect of 11 shape of concentric tube of the present invention is can
So that soot gas generates vortex in 11 inner wall of concentric tube, the efficiency of removing oil smoke is improved.
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 to be connect with exhausting component 5
One end, as 11 gas outlet of concentric tube, the other end of concentric tube 11 is 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.Again according to Bernoulli's theorem it is found that the speed of gas to get over high pressure smaller, therefore concentric tube 11 is connect with exhausting component 5
An end pressure it is big, and the pressure of the air inlet of concentric tube 11 is small, to increase the air inlet and external environment of concentric tube 11
Pressure difference improves oil absorbing effect from promoting soot gas to enter.

22 integrally connected shell, 2 corresponding inner surface and with positioned at the edge of housing inlet 21, annular lamina 22 and housing inlet 21
It corresponds, annular lamina 22 of the invention can also be fixedly installed in shell, depending on specific embodiment is with performance.Outside
Shell 2 is spherical housing 2.
The effect of annular lamina 22 is vortex to be generated when soot gas being made to enter shell 2, while preventing soot particles from throwing away again
When oil fume separator 1 exterior space is thrown away from the housing inlet 21 of shell 2.
The operation principle of the kitchen ventilator is：Kitchen ventilator is opened, motor 4 drives oil fume separator 1, the wind wheel of exhausting component 5
It rotating simultaneously, soot particles pass through seven layer separations inside kitchen ventilator, and most almost the gas of cleaning is discharged through gas outlet again finally,
As shown in Figure 5.This seven layer separation is specific as follows：
First layer separation, inertial separation：Oil smoke enters via the housing inlet 21 of shell 2 inside smoke machine, and oil smoke enters
Enter annular lamina 22 after housing inlet 21, because of 21 area of pressure difference and housing inlet of shell 2 inside and external environment
Cataclysm, air velocity can accelerate, and moment of inertia also relative increases.And oil smoke can form very thin around annular lamina 22
Boundary layer, and because the housing inlet 21 and annular lamina 22 of shell 2 are in angle, oil smoke is forced to flow downward along annular lamina 22
Just up flow into oil fume separator 1 afterwards, thus heavier oil opened with crude oil plume field point in downward inertia motion it is past
The oil collector sump tank 3 in 2 bottom of shell is collected in lower movement, 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 of wheel interacts.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 takes away or stops into 11 inside of concentric tube and move outward, then is 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 by centrifugal force and attract force effect, but opposite attraction be 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 centrifuging force effect, 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, and the cyclone centrifugal force of concentric tube 11 and secondary vortex generate：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, which is blocked, to be flowed up.It is vortexed, does not stop in addition, remaining oil smoke can be formed in vortex generator
Spinning captures oil smoke and does not allow oil smoke 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 is stopped not because of the unstability in flow field 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 difference and the wind wheel for sucking exhausting component 5, the wind wheel of rotation form centrifugal force and remaining a small amount of soot particles are thrown to wind turbine
Inner wall on, last almost clean gas is discharged external through gas outlet.
The kitchen ventilator with lightweight, oil resistant, heat safe oil fume separator, oil fume separator 1 rotation generate it is additional from
Mental and physical efforts can effectively remove the removal effect that soot particles improve oil smoke, and soot particles is avoided to enter exhausting component 5 to reduce
The noise that the oil stain accumulation opposite of wind wheel generates.Oil fume separator 1 has the advantages that light weight, oil resistant and heat safe simultaneously.
