The shell 2 of the utility model is spherical housing 2.
The working principle of the kitchen ventilator is: opening kitchen ventilator, motor 4 drives oil fume separator 1, the wind wheel of exhausting component 5
It rotating simultaneously, soot particles are by seven layers of separation inside kitchen ventilator, and most almost the gas of cleaning is discharged through gas outlet again finally,
As shown in Figure 9.This seven layers separation are specific as follows:
First layer separation, inertial separation: oil smoke enters inside smoke machine via the housing inlet 21 of shell 2, 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 shell 2 housing inlet 21 and annular lamina 22 be in angle, force oil smoke along annular lamina 22 will to flow down
Oil fume separator 1 is just up flowed into after dynamic, 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: the soot particles by first layer separation are in the direction of annular lamina 22 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 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 separating for the second time, 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, the centrifugal force of 13 outermost end of eaves portion structure can segment fluid flow or
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 grain
Son can fall in annular lamina 22, flow to oil collector sump tank 3 finally along annular lamina 22.
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 22
Move oil collector sump tank 3.
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 3 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 5, 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.
The oil smoke is repeatedly centrifugated the work that can increase soot particles and the generation centrifugal force of oil fume separator 1 of formula kitchen ventilator
With area, under identical rotation speed and under identical 11 diameter of concentric tube, angle can improve the tangent line speed that soot particles are thrown away
It spends, under oil fume separator 1, is detached from soot particles inside oil fume separator 1, improves the separating effect of oil smoke.The oil smoke is multiple
The oil fume separator 1 of centrifuge separation formula kitchen ventilator generates additional centrifugal force, can effectively remove soot particles, greatly improve oil smoke
The separating effect of particle.The oil smoke, which is repeatedly centrifugated formula kitchen ventilator and is avoided that, simultaneously connects containing a large amount of soot particles gases with wind wheel
Touching, can effectively remove soot particles inside kitchen ventilator.
