On the tube wall of concentric tube 110, while also further ensureing that smoke machine can reach perfect cleaning during self-cleaning
Effect.
The exhausting component for reaching cleaning function using positive pressure can proceed through seven layers to oil smoke in use
Separation, most almost the gas of cleaning is discharged through gas outlet again finally.This seven layers separation are specific as follows:
This seven layers separation are specific as follows:
First layer separation, inertial separation: oil smoke enters inside shell 201 via the first air inlet 2011 of shell 201,
Oil smoke enters the first arc-like sheet 2012 after entering 201 first air inlet 2011 of shell, because of 201 inside of shell and external environment
The cataclysm of 2011 area of pressure difference and the first air inlet, air velocity can be accelerated, and moment of inertia also relative increases.And oil smoke
Very thin boundary layer can be formed around arc-like sheet, and because of the first air inlet 2011 and the first arc-like sheet 2012 of shell 201
In angle, force oil smoke along the first arc-like sheet 2012 to flow downward after just up flow into oil fume separator 100, therefore compared with
The oil of weight separates movement collection down in the oil collector sump tank of 201 bottom of shell in downward inertia motion with crude oil plume field
202, realize first time inertial separation.
The second layer separation, cyclonic separation: by first layer separation soot particles the direction of the first arc-like sheet 2012 by
Further occurrence flow field separates in flowing on lower turn, and soot particles cause unsteady flow field, further shape in the case where flow field separates
At vortex.Flow field or vortex can interact influence with neighbouring flow field or vortex, not stop certainly in the formation of 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 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, is centrifuged
Power and the attraction of blower interact.After separating for the first time, the lighter oil smoke of remaining part is when entering concentric tube 110
The outermost end for first touching annular fan blades 105 enters back into concentric tube 110, and the centrifugal force of annular 105 outermost end of fan blades can be part
Fluid or soot particles take away or stop to enter 110 inside of concentric tube and move outward, then are thrown to 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 of separation, inertial separation and centrifugal force separate: inertial separation and centrifugal force separate: after third layer separates,
The oil smoke of remaining lighter weight is acted on by centrifugal force and attraction simultaneously, but opposite attraction is greater 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 other oil smoke or
Person's soot particles pool larger soot particles flow down, and because of centrifugal force effect, soot particles and 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 separation, the cyclone centrifugal force of concentric tube 110 and secondary vortex generate: 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. are mobile toward duct wall, tube wall shape
At high tangential velocity, part oil smoke, which is blocked, to be flowed up.It is vortexed in addition, remaining oil smoke can be formed in vortex generator,
Do not stop spinning, captures 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
Turn secondary vortex flow 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 separation, secondary vortex flow formation component 107 separate: the secondary vortex flow formation component 107 of 110 one end of concentric tube
Remaining oil smoke is generated, flow field separation occurs, separated by flow field, part oil smoke is stopped not because of the unstability in flow field
It is flowed on toward length and the vortex of spinning captures oil smoke.
203 centrifugal force separate of exhausting component: layer 7 separation after first four layers separation, is left a small amount of oil very light
The air-flow that blower of smoke particle due to pressure difference from by exhausting component 203 is rotated and formed excludes, and the blower of rotation is formed
Centrifugal force is thrown to remaining a small amount of soot particles on the inner wall of blower, and last almost clean gas is discharged outer through gas outlet
Portion, while also ensuring 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 that exhausting component 203 for the extracting force of oil smoke, while facilitating later use positive pressure also to clear up
A small amount of greasy dirt of attachment.
