In this embodiment, the secondary vortex generating assembly 107 is disposed between any concentric tube 110 and the ring-shaped fan 105, but it should be noted that the secondary vortex generating assembly 107 is not limited to be disposed only between any concentric tube 110 and the ring-shaped fan 105, and may be disposed in the concentric tube 110 according to actual user requirements.
In this embodiment, the number of the secondary vortex generating assemblies 107 is 2, and 2 secondary vortex generating assemblies 107 are respectively disposed at the end of the inner air inlet 140 of the 2 nd concentric tube 110 and the end of the inner air inlet 140 of the 3 rd concentric tube 110. The oil stain attached to the pipe wall of the concentric pipe 110 after being cleaned by the vortex flow field generated by the secondary vortex generating assembly 107 through the high-speed rotation of the secondary vortex generating assembly 107 can be guided into the flow guide area of the annular fan sheet 105 again, the oil stain is cleaned from the pipe wall of the concentric pipe 110, and then the oil smoke is prevented from being attached to the pipe wall of the concentric pipe 110.
The smoke machine in the resonance type smoke separation smoke machine can separate smoke by eight layers when the smoke machine sucks smoke, and finally almost clean gas is discharged through the gas outlet. The eight layer separations are specifically as follows:
the eight layer separations were specifically as follows:
first layer separation, inertial separation: the oil smoke enters the inside of the housing 201 through the first air inlet 2011 of the housing 201, and the oil smoke enters the first arc-shaped sheet 2012 after entering the first air inlet 2011 of the housing 201, because of the pressure difference between the inside of the housing 201 and the external environment and the abrupt change of the area of the first air inlet 2011, the speed of the air flow is accelerated, and the inertia momentum is relatively increased. And the oil smoke can form a very thin boundary layer around the arc-shaped sheet, and because the first air inlet 2011 of the shell 201 forms an included angle with the first arc-shaped sheet 2012, the oil smoke is forced to flow upwards and enter the oil smoke separator 100 after flowing downwards along the first arc-shaped sheet 2012, so that the heavier oil and the crude oil smoke flow field move downwards separately in the downward inertial motion and are collected in the second oil collecting device 202 at the bottom of the shell 201, and the first inertial separation is realized.
Second layer separation, vortex separation: the oil smoke particles separated by the first layer further undergo flow field separation from the upward flowing flow in the direction of the first arc-shaped sheet 2012, and the oil smoke particles cause an unstable flow field under the flow field separation, so as to further form a vortex. The flow field or the vortex can interact and influence with the adjacent flow field or the vortex, a continuously rotating flow field is formed on the first arc-shaped sheet 2012, and the rotating vortex reaches the maximum vortex amount. The remaining light oil smoke will not stop at the rotating vortex of the first arced sheet 2012 and accumulate to a certain weight, and the flow field will not support the weight of the oil drop and will fall down or flow along the first arced sheet 2012 to the second oil collecting device 202.
Third layer separation, centrifugal separation: the ring sectors 105 rotate with the concentric tube of oil 110 creating centrifugal force which interacts with the suction of the fan. After the first separation, when the remaining lighter oil smoke enters the concentric tube 110, the remaining lighter oil smoke contacts the outermost end of the annular fan blade 105 and then enters the concentric tube 110, the centrifugal force at the outermost end of the annular fan blade 105 can enable a part of fluid or oil smoke particles to be separated or blocked from entering the concentric tube 110 and moving outwards, then the fluid or oil smoke particles are thrown onto the first arc-shaped piece 2012 of the shell 201 at a higher linear cutting speed, and the oil smoke on the first arc-shaped piece is thrown onto the shell 201 again.
Fourth layer separation, inertial separation and centrifugal separation: inertial separation and centrifugal separation: after the third layer of separation, the remaining oil smoke with lighter weight is subjected to the centrifugal force and the attraction force at the same time, but the relative attraction force is larger than the centrifugal force. Some of the oil smoke will flow to the adjacent ring-shaped fan blades 105 through the through holes 106, and will be gathered with other oil smoke or oil smoke particles into larger oil smoke particles to flow downward due to the inertia effect, and due to the centrifugal force, the oil smoke particles will be thrown out of the ring-shaped fan blades 105105 again at a higher tangential speed, and will be thrown onto the housing 201 again.
Fifth layer separation, cyclonic centrifugal force and secondary vortex generation of concentric tubes 110: the inner wall of the concentric tube 110 rotates to form a cyclone, the concentric tube 110 is a low-pressure area, fluid or particles in the tube move towards the wall of the tube under the action of centrifugal force, the tube wall forms a high tangential velocity, and part of oil smoke is blocked from flowing upwards. In addition, the residual oil smoke can form vortex in the vortex generating device, and the vortex generating device does not stop rotating, so that the oil smoke is captured and cannot escape from the concentric pipe 110. When the attraction force and the centrifugal force are removed, the oil smoke continuously rotating in the second vortex and moving along the high tangential line on the wall of the concentric tube 110 flows downward along the inner wall of the concentric tube 110 due to gravity.
Sixth layer separation, secondary vortex generation assembly 107 separation: the secondary vortex generating component 107 at one end of the concentric tube 110 generates flow field separation on the remaining oil smoke, and the oil smoke is captured by the vortex which is formed by blocking part of the oil smoke from flowing upwards and rotating automatically due to the instability of the flow field.
Seventh layer separation, air draft assembly 203 centrifugal separation: after the separation of the first four layers, a small amount of very light oil smoke particles are left to be discharged from the airflow formed by the rotation of the fan in the air draft assembly 203 due to pressure difference, the rotating fan forms centrifugal force to throw the remaining small amount of oil smoke particles to the inner wall of the fan, finally, almost clean gas is discharged outside through the air outlet, and meanwhile, the air draft assembly 203 is also ensured not to have excessive oil stains attached to the air draft assembly 203 in the daily use process. But also ensures the suction force of the air draft assembly 203 on the oil smoke, and simultaneously facilitates the subsequent positive pressure cleaning of a small amount of attached oil stain.
Eighth layer separation, resonance separation: after the first seven layers of separation, a small amount of very light oil smoke particles are left to rotate along with the generated vortex in the inner part and keep consistent with the vibration frequency of the vortex, when passing through the spring 301, the particles can be firstly attached to the outer wall surface of the spring 301, when the spring 301 resonates with the vortex in the cigarette machine body or the vibration of the air draft assembly, the particles can shake up and down to the maximum extent, then the oil smoke is thrown out, the thrown-out oil smoke can be thrown out again along with the centrifugal force and the negative pressure generated by the oil smoke separation device, and finally, almost clean gas is discharged out of the outer part through the air draft assembly.
