In the top of oil fume separator 1, oil collector sump tank 3 is assemblied in the bottom of shell 2.
Shell 2, which is provided with, is integrally connected to the corresponding interior table of shell 2 with the matched annular lamina 22 of air inlet 21, annular lamina 22
Face and be located at air inlet 21 edge.The annular lamina 22 of the utility model can also be fixedly installed in shell 2, specific to implement
Depending on mode is with performance.
The effect of annular lamina 22 is vortex to be generated when soot gas being made to enter shell 2, while preventing soot particles from throwing away again
Exterior space is thrown away from the air inlet 21 of shell 2 when oil fume separator 1.
Exhausting component 5 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 shell of the utility model is axially symmetric structure.
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 rotates 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.
This seven layers separation are specific as follows:
First layer separation, inertial separation: oil smoke enters inside smoke machine via the air inlet 21 of shell 2, 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 and annular lamina 22 are in angle, 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: 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 pumping
The attraction of wind component 5 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 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.
Guide surface of the outer surface of the kitchen ventilator as oil smoke moving direction, and non-formation area is provide with for gather oil smoke
Domain can have separation soot particles in inside.The oil fume separator of the kitchen ventilator and the kitchen ventilator than the prior art generates 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
Touching, greatly improves the separating effect of soot particles.
