Smoke machine main body is additionally provided with exhausting component and oil collector sump tank 3, and exhausting component is fixedly installed in the inside of shell 2 and position In the top of oil fume separator 1, exhausting component is also connect with gas outlet, and oil collector sump tank 3 is detachably assemblied in the bottom of shell 2.
Exhausting component 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, Spiral case is fixedly installed in smoke machine body interior, and the air inlet of spiral case is communicated with the gas outlet of 11 top of concentric tube, the outlet of spiral case Mouth is communicated with the gas outlet of smoke machine main body.The shell 2 of the present invention is spherical structure.
The operation principle of the kitchen ventilator is:Kitchen ventilator is opened, motor 4 drives oil fume separator 1, and the wind wheel of exhausting component is same When rotate, soot particles are by seven layer separations inside kitchen ventilator, and most almost clean gas is discharged again through gas outlet finally, such as Shown in Figure 11.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 Just up flow into oil fume separator 1 afterwards, thus heavier oil opened in downward inertia motion with crude oil plume field point 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 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 oil fume separator 1 of the kitchen ventilator of the fast eliminating soot particles can effectively remove soot particles, avoid oil smoke grain Son discharge gas outlet, while through-hole 131 can will pool the elaioleucite of bulky grain when oil fume separator 1 rotates, and be detached from oil Inside cigarette separator 1, the separating effect of soot particles is greatly improved.

Because EThrough-hole 131Crossing conference reduces the area of eaves portion structure 13, so as to reduce 13 surface of eaves portion structure to oil smoke The influence of particle.
When the gross area area of through-hole 131 is excessive, effect of the centrifugal force in eaves portion structure 13 can be weakened.In order to ensure eaves The centrifugal force of portion's structure 13 and the inertial separation of via through holes 131 reach maximum efficiency, and the gross area of through-hole 131 need to be less equal than The gross area 30% of place eaves portion structure 13.The gross area of through-hole 131 can then weaken the gas of entrance in oil machine very much greatly simultaneously The flow velocity in portion.
