Smoke machine main body is provided with exhausting component 4,4 fixing assembling of exhausting component in non-planar shell 2 inside and be located at oil
The top of cigarette separator 1.
Non-planar shell 2 is additionally provided with non-planar housing main body 21 and oil collector sump tank 22, and non-planar housing main body 21 assembles
In the outer surface of smoke machine main body, oil collector sump tank 22 is assemblied in the bottom of non-planar housing main body 21, air inlet 211 and annular lamina
212 are distributed in non-planar housing main body 21.
Exhausting component 4 is provided with blower, wind wheel and spiral case, and blower is assemblied in inside spiral case, and wind wheel and blower are sequentially connected,
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 working principle of the non-planar kitchen ventilator is: opening non-planar kitchen ventilator, motor 3 drives oil fume separator 1, exhausting
The wind wheel of component 4 rotates simultaneously, soot particles inside non-planar kitchen ventilator by seven layers of separation, most almost clean gas finally
Body is discharged through gas outlet again.This seven layers separation are specific as follows:
First layer separation, inertial separation: oil smoke via non-planar shell 2 air inlet 211 enter smoke machine inside, oil smoke into
Enter annular lamina 212 after entering air inlet 211, because of 211 face of pressure difference and air inlet of non-planar shell 2 inside and external environment
Long-pending cataclysm, air velocity can be accelerated, and moment of inertia also relative increases.And oil smoke can be formed very around annular lamina 212
Thin boundary layer, and because the air inlet 211 and annular lamina 212 of non-planar shell 2 are in angle, force oil smoke along annular lamina 212
Just up flow into oil fume separator 1 after flowing downward, thus heavier oil in downward inertia motion with crude oil cigarette
Flow field separates movement collection down and realizes first time inertial separation in the oil collector sump tank 22 of non-planar 2 bottom of shell.
Second layer separation, cyclonic separation: the soot particles by first layer separation are in the direction of annular lamina 212 by lower turn
Flowing in further occurrence flow field separation, soot particles flow field separate 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 212, 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 212, 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 212
22。
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 4 interacts.After separating for the second time, 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 to enter 11 inside of concentric tube and move outward, then are thrown away with higher tangential velocity, are thrown out of
Particle can fall in annular lamina 212, flow to oil collector sump tank 22 finally along annular lamina 212.
4th layer of separation, inertial separation and centrifugal force separate: after third layer separates, the oil smoke of remaining lighter weight is same
When acted on by centrifugal force and attraction, but opposite attraction is greater 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, and because centrifugal force acts on, soot particles are simultaneously flowed with throwing away compared with high tangential velocity finally along annular lamina 212
Move oil collector sump tank 22.
Layer 5 separation, 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 mobile 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
It can be collected because gravity flows downward to oil collector sump tank 22 along inner tubal wall in the oil smoke that tube wall carries out high tangential motion.
Layer 6 separation, disturbing flow device 111 separate: the disturbing flow device 111 of 11 one end of concentric tube generates remaining oil smoke
Flow field separation occurs, is separated 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 separation, wind wheel centrifugal force separate: after the separation of the first six layer, be left a small amount of soot particles very light because
Pressure difference and the wind wheel for sucking exhausting component 4, the wind wheel of rotation form centrifugal force and remaining a small amount of soot particles are thrown to blower
Inner wall on, last almost clean gas is discharged external through gas outlet.
Guide surface of the outer surface of the non-planar kitchen ventilator as oil smoke moving direction, and it is non-formation for gathering oil smoke
It is provide with region, while the removal effect of oil smoke can be substantially increased.There are also generate to soot gas for the oil smoke separation assembly simultaneously
Additional centrifugal force can effectively remove soot particles, be avoided that and contact containing a large amount of soot particles gases with wind wheel, greatly improve oil
The noise that the separating effect of smoke particle and reduction are generated because wind wheel accumulates grease stain.
Embodiment 2.
A kind of non-planar kitchen ventilator, other features are same as Example 1, the difference is that: the n=4 of the present embodiment, i.e.,
The concentric tube 11 of the present embodiment is provided with 4.The present embodiment m=2, i.e. vortex generating means group 14 are set as 2, a setting
In the 4th concentric tube, another is set to the 3rd concentric tube.The concentric tube 11 of the present embodiment and eaves portion structure 13 correspond simultaneously.
The non-planar kitchen ventilator compared with Example 1, increases a concentric tube 11, that is, increase oil fume separator
11 spatial volume inside non-planar shell 22 improves gas and enters speed to reduce the area of 11 air inlet of concentric tube
Degree increases the pressure difference of 11 inside and exterior space of concentric tube, so as to improve the rate of departure of soot particles.
Embodiment 3.
A kind of non-planar kitchen ventilator, other features are same as Example 1, the difference is that: annular lamina 212 with it is corresponding into
