The diameter of one end of concentric tube 11 is greater than the diameter of the other end.One end of concentric tube 11 is to connect with exhausting component One end, as 11 gas outlet of concentric tube, the other end of concentric tube 11 are the air inlet of concentric tube 11, can according to Venturi effect Know, the bigger flow velocity of the area that fluid flows through is smaller, i.e. the other end of the speed of one end of gas concentric pipe 11 greater than concentric tube 11 Speed.According to Bernoulli's theorem, it is found that the speed of gas is got over, high pressure is smaller again, therefore concentric tube 11 is connect with exhausting component One end pressure is big, and the pressure of the air inlet of concentric tube 11 is small, to increase the air inlet of concentric tube 11 and the pressure of external environment Power is poor, from promoting soot gas to enter, improves oil absorbing effect.
Smoke machine main body is provided with shell 2, exhausting component and oil collector sump tank 3, and shell 2 is assemblied in the outer surface of smoke machine main body, Oil fume separator 1 is driven the inside for being installed on shell 2, and exhausting component fixing assembling is in 2 inside of shell and is located at oil fume separator 1 Top, oil collector sump tank 3 is assemblied in the bottom of shell 2.
Shell 2 be provided with multiple housing inlets 21 and with the matched annular lamina 22 of multiple housing inlets 21, annular lamina The corresponding inner surface of 22 integrally connected shell 2 and with the edge that is located at housing inlet 21, annular lamina 22 and housing inlet 21 Correspond, the annular lamina 22 of the utility model can also be fixedly installed in shell, specific embodiment with performance and It is fixed.
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 housing inlet 21 of shell 2 when oil fume separator 1.
Oil fume separator 1 is provided with rotary shaft 12, and rotary shaft 12 connects with the fixed of one end of a plurality of concentric tube 11 respectively It connects, the motor 4 of rotary shaft 12 and smoke machine main body is sequentially connected.
Exhausting component 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 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, and the wind wheel of exhausting component is same When rotate, soot particles are by seven layers of separation inside kitchen ventilator, and most almost clean gas is discharged through gas outlet again finally.This Seven layers of 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, the wind wheel of rotation form centrifugal force and remaining a small amount of soot particles are thrown to blower On inner wall, last almost clean gas is discharged external through gas outlet.
The eaves portion structure 13 that the internal gas flow is uniformly distributed formula kitchen ventilator can be by the air-flow of aggregation even into concentric tube 11 Inside oil removing, to propose whole oil removing ability.More internal gas flows are uniformly distributed 1 energy of oil fume separator of formula kitchen ventilator simultaneously Additional centrifugal force is generated, soot particles can be effectively removed, avoids soot particles from entering exhausting component, is avoided that containing soot particles Air contacted with wind wheel, greatly improve the separating effect of soot particles.
