It is communicated with the gas outlet of smoke machine main body.Shell 2 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 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 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 the housing inlet 21 and annular lamina 22 of shell 2 are in angle, force oil smoke 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: 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 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.
The shell 2 of the kitchen ventilator, which can be dismantled, has the advantages that convenient for cleaning and maintenance.The shell of the shell 2 or oil resistant
2 be easily detachable after cleaning.While the shell 2 can make soot gas generate vortex to separation or filter soot particles,
Reduce production cost.The oil fume separator 1 of the kitchen ventilator generates additional centrifugal force, can effectively remove soot particles, significantly
Improve the separating effect of soot particles.
