Concentric tube 111 is the line segment that is made of multistage broken line around concentric tube 111, concentric tube 111 formed by axis one week
For vortex position 1112 occurs for the position that the adjacent two lines section of inner wall intersects.The effect of 111 shape of concentric tube of the present invention is
Soot gas can be made to generate vortex in 111 inner wall of concentric tube, improve the efficiency of removing oil smoke.
The diameter of one end of concentric tube 111 is more than the diameter of the other end.One end of concentric tube 111 is connects with exhausting component 4
The one end connect, as 111 gas outlet of concentric tube, the other end of concentric tube 111 is the air inlet of concentric tube 111, according to venturi
Effect is it is found that the bigger flow velocity of area that flows through of fluid is smaller, i.e., the speed of one end of gas concentric pipe 111 is more than concentric tube 111
Other end speed.Again according to Bernoulli's theorem it is found that the speed of gas to get over high pressure smaller, therefore concentric tube 111 and exhausting
The end pressure that component 4 connects is big, and the pressure of the air inlet of concentric tube 111 is small, so as to increase the air inlet of concentric tube 111 with
The pressure differential of external environment from soot gas is promoted to enter, improves oil absorbing effect.

The end at end.The effect of disturbing flow device 1111 is that soot gas is made to generate vortex, so as to improve the ability of de-oiling.
Eaves portion structure 113 is provided with multiple through-holes 1131.The effect of through-hole 1131 is can be rotated in oil smoke separation assembly 1
When, the elaioleucite of bulky grain will be pooled, is detached from inside oil smoke separation assembly 1, greatly improves the separating effect of soot particles.
The operation principle of the kitchen ventilator is：Kitchen ventilator is opened, motor drives oil smoke separation assembly 1, the wind wheel of exhausting component 4
41 rotate 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 21 of shell 2 inside smoke machine, and oil smoke enters
Enter annular lamina 22 after housing inlet 21, because of 2 inside of shell and 21 area of pressure differential and housing inlet of external environment
Cataclysm, air velocity can accelerate, and moment of inertia also relatively 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
Oil smoke separation assembly 1 is just up flowed into afterwards, therefore heavier oil separates in downward inertia motion with crude oil plume field
The oil collector sump tank 3 in 2 bottom of shell is collected in movement down, 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 113 follows the rotation of concentric tube 111 to form centrifugal force, centrifugal force with
The attraction interaction of exhausting component 4.After second detaches, the lighter oil smoke of remaining part is entering concentric tube 111
When first touch the outermost end of eaves portion structure 113 and enter back into concentric tube 111, the centrifugal force of 113 outermost end of eaves portion structure can be portion
Shunting body or soot particles are taken away or stop into 111 inside of concentric tube and move outward, then got rid of with higher tangential velocity
Go out, being thrown out of particle can fall 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 acted on by centrifugal force and attraction, but opposite attraction is more than centrifugal force.A portion of these oil smoke can be through
Through-hole 1131 is crossed to flow to adjacent eaves portion structure 113, because effect of inertia pool with other oil smoke or soot particles it is larger
Soot particles flow down, and because of centrifugal force effect, soot particles and to be thrown away compared with high tangential velocity finally along annular lamina 22
It flow to oil collector sump tank 3.
Layer 5 detaches, the cyclone centrifugal force of concentric tube 111 and the secondary generation that is vortexed：111 inner wall of concentric tube rotates to be formed
Cyclone, concentric tube 111 be low-pressure area under the action of the centrifugal force, fluids within pipes or particle etc. toward duct wall move, tube wall shape
Into high tangential velocity, part oil smoke is blocked flowing up.It is vortexed in addition, remaining oil smoke can be formed in vortex generator,
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 vortices of spinning are not stopped
The oil smoke for flowing and high tangential motion being 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 1111 detaches：The disturbing flow device 1111 of 111 one end of concentric tube produces remaining oil smoke
Hair tonic life flow field separation, detaches by flow field, part oil smoke because stopping during the unstability in flow field not toward flowing in length and certainly
The vortex of rotation captures oil smoke.
Layer 7 detaches, 41 centrifugal force separate of wind wheel：After the first six layer separation, it is left a small amount of very light soot particles
The wind wheel 41 of exhausting component 4 is sucked due to pressure differential, the wind wheel 41 of rotation forms centrifugal force and remaining a small amount of soot particles are got rid of
Onto the inner wall of wind turbine 42, last almost clean gas is discharged external through gas outlet.
The centrifugal force that 1 soot gas of oil smoke separation assembly of the kitchen ventilator generates is adjusted, vortex generating means group 12
Gas is made, which to generate vortex, to be increased the collision probability of soot particles and becomes big particle so as to greatly improve the deoiling effect of kitchen ventilator.
The kitchen ventilator is avoided that and is contacted containing a large amount of soot particles gases with wind wheel 41 simultaneously, greatly improve the separating effects of soot particles with
Reduce the noise generated due to wind wheel 41 accumulates oil stain.
