When oil fume separator 1 exterior space is thrown away from the air inlet 21 of shell 2.
Exhausting component 5 is provided with wind turbine, wind wheel and spiral case, and wind turbine is assemblied in inside spiral case, and wind wheel is sequentially connected with wind turbine,
The air inlet that spiral case is fixedly installed in smoke machine body interior spiral case is communicated with the gas outlet of 11 top of concentric tube, the gas outlet of spiral case
It is communicated with the gas outlet of smoke machine main body.The shell of the present invention is axially symmetric structure.
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 rotates 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.
This seven layer separation is specific as follows：
First layer separation, inertial separation：Oil smoke enters via the air inlet 21 of shell 2 inside smoke machine, and oil smoke enters air inlet
Enter annular lamina 22 after mouth 21, because of the cataclysm of shell 2 inside and 21 area of pressure difference and air inlet of external environment, gas velocity
Degree can be accelerated, and moment of inertia also relative increases.And oil smoke can form very thin boundary layer around annular lamina 22, and because
The air inlet 21 of shell 2 is in angle with annular lamina 22, force oil smoke along annular lamina 22 to flow downward after just up flow into
Oil fume separator 1, therefore heavier oil separates movement down with crude oil plume field in downward inertia motion and collects in shell 2
The oil collector sump tank 3 of bottom 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 pumping
The attraction of wind component 5 interacts.After second detaches, the lighter oil smoke of remaining part is first when entering concentric tube 11
The outermost end for touching eaves portion structure 13 enters back into concentric tube 11, the centrifugal force of 13 outermost end of eaves portion structure can segment fluid flow or
Person's soot particles take away or stop into 11 inside of concentric tube and move outward, then are thrown away with higher tangential velocity, are thrown out of
Particle can be fallen in annular lamina 22, and 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.
Guide surface of the outer surface of the kitchen ventilator as oil smoke moving direction, and non-formation it is provide with area for gather oil smoke
Domain can have separation soot particles in inside.The kitchen ventilator with than the oil fume separator of the kitchen ventilator of the prior art generate it is additional
Centrifugal force can effectively remove soot particles, avoid soot particles from entering exhausting component, be avoided that and connect containing soot particles and wind wheel
It touches, greatly improves the separating effect of soot particles.
