It is respectively arranged at the end of the interior air inlet 140 of the 2nd concentric tube 110 and the end of air inlet 140 in the 3rd concentric tube 110.
In the present embodiment, secondary vortex flow formation component 107 is set between arbitrary concentric tube 110 and annular fan blades 105,
It should be understood that secondary vortex flow formation component 107 is not only confined to be set to arbitrary concentric tube 110 and annular fan
Between piece 105, it can also need to be set in concentric tube 110 according to practical user.
Secondary vortex flow formation component 107 is set as 2 in the present embodiment, and 2 secondary vortex flow formation components 107 are set respectively
In the end of the interior air inlet 140 of the 2nd concentric tube 110 and the end of air inlet 140 in the 3rd concentric tube 110.It is secondary by setting
The vortex flow field that vortex formation component 107 is generated by the high speed rotation of itself of secondary vortex flow formation component 107 can be cleared up
The greasy dirt being attached to afterwards on the tube wall of concentric tube 110 imports the water conservancy diversion region of annular fan blades 105 again, by greasy dirt from concentric tube
It clears up away on 110 tube wall, oil smoke will be then unlikely on the tube wall for being attached to concentric tube 110, while is also further
Ensure that the clean technologies can reach perfect cleaning performance during self-cleaning smoke machine.
This using positive/negative-pressure carry out oil smoke cleaning smoke machine in smoke machine to oil smoke aspirate oil smoke when can to oil smoke into
It passed through seven layer separations, most almost clean gas is discharged again through gas outlet finally.This seven layer separation is specific as follows：
This seven layer separation is specific as follows：
First layer separation, inertial separation：Oil smoke enters via the first air inlet 2011 of shell 201 inside shell 201, oil
Cigarette enters the first arc-like sheet 2012 after entering 201 first air inlet 2011 of shell, because of 201 inside of shell and the pressure of external environment
The cataclysm of 2011 area of force difference and the first air inlet, air velocity can be accelerated, and moment of inertia also relatively increases.And oil smoke meeting
Very thin boundary layer is formed around arc-like sheet, and because the first air inlet 2011 of shell 201 is in the first arc-like sheet 2012
Angle just up flows into oil fume separator 100, therefore heavier after oil smoke is forced to flow downward along the first arc-like sheet 2012
Oil separate with crude oil plume field movement collection down in downward inertia motion in the second oil collector sump tank of 201 bottom of shell
202, realize first time inertial separation.
Second layer separation, cyclonic separation：Soot particles by the first layer separation the direction of the first arc-like sheet 2012 by
Flow field separation further occurs in flowing on lower turn, soot particles cause unsteady flow field, further shape under being detached in flow field
Into vortex.Flow field or vortex can interact influence with neighbouring flow field or vortex, formed and do not stopped certainly in the first arc-like sheet 2012
The flow field of rotation, rotating vortex at this moment reach maximum vorticity.The lighter oil smoke of remaining part can not be parked in the first arc-like sheet
2012 rotating vortex accumulation, when running up to constant weight, flow field branch is unable to hold out the weight of oil droplet, will fall downwards or along
First arc-like sheet 2012 is flow in the second oil collector sump tank 202.
Third layer separation, centrifugal force separate：Annular fan blades 105 follows the oily rotation of concentric tube 110 to form centrifugal force, centrifugal force
It interacts with the attraction of wind turbine.After being detached through first time, the lighter oil smoke of remaining part is first when entering concentric tube 110
The outermost end for touching annular fan blades 105 enters back into concentric tube 110, and the centrifugal force of annular 105 outermost end of fan blades can flow part
Body or soot particles are taken away or stop into 110 inside of concentric tube and move outward, then be thrown to outside with higher tangential velocity
On first arc-like sheet 2012 of shell 201, the oil smoke on the first arc is thrown to again on shell 201.
4th layer separation, inertial separation and centrifugal force separate：Inertial separation and centrifugal force separate：After third layer separation,
The oil smoke of remaining lighter weight is acted on simultaneously by centrifugal force and attraction, but opposite attraction is more than centrifugal force.This
A portion of a little oil smoke can be flowed by through-hole 106 to adjacent annular fan blades 105, because of effect of inertia and others oil smoke or
Person's soot particles pool larger soot particles flow down, and because of centrifugal force effect, soot particles and with compared with high tangential velocity
It is thrown out of annular fan blades 105105 again, and soot particles are thrown on shell 201 again.
Layer 5 detaches, the cyclone centrifugal force of concentric tube 110 and the secondary generation that is vortexed：110 inner wall of concentric tube rotates to be formed
Cyclone, concentric tube 110 be low-pressure area under the action of the centrifugal force, fluids within pipes or particle etc. toward duct wall move, tube wall shape
Into high tangential velocity, part oil smoke is blocked flowing up.It is vortexed in addition, remaining oil smoke can be formed in vortex generator,
Do not stop spinning, capture oil smoke and oil smoke is not allowed to flee from 110 pipeline of concentric tube.After attraction and centrifugal force remove, do not stop to spin
The secondary vortex flow that turns and 110 wall of concentric tube carry out high tangential motion oil smoke can along 110 inner tubal wall of concentric tube because gravity to
Lower flowing.
Layer 6 detaches, and secondary vortex flow formation component 107 detaches：The secondary vortex flow formation component 107 of 110 one end of concentric tube
Remaining oil smoke is generated, flow field separation occurs, detached by flow field, part oil smoke because stopping not during the unstability in flow field
The vortex of flowing and spinning captures oil smoke on toward length.
Layer 7 detaches, 203 centrifugal force separate of exhausting component：After preceding four layer separation, it is left a small amount of very light oil
The air-flow that wind turbine of smoke particle due to pressure differential from by exhausting component 203 is rotated and formed excludes, and the wind turbine of rotation is formed
Centrifugal force is thrown to remaining a small amount of soot particles on the inner wall of wind turbine, and last almost clean gas is discharged outer through gas outlet
Portion, while also ensure that the exhausting component 203 does not have excessive greasy dirt during routine use and is attached to exhausting component 203
It is interior.And also ensure extracting force of the exhausting component 203 for oil smoke, while it is attached to clear up to be also convenient for later use positive pressure
The a small amount of greasy dirt.
