Height of the 1 st concentric tube is H 1 ,. i ,. n-1 The height of the n-th concentric tube is H n ，H 1 Has the maximum value of H n The value of (c) is minimal. 1.1H n ≤H i ≤10H n And 0.5H i-1 ≤H i ≤3H i-1 。
The included angle between the plane of the eave structure 13 and the central axis of the concentric tube 11 is A, the included angle A is specifically 80 degrees, and can also be any angle between 20 degrees and A < 180 degrees, which is determined by actual conditions.
This eaves portion structure 13 is the effect that the contained angle is with the other end of concentric tube 11 can increase the effect area that oil smoke particle and oil smoke separator 1 produced the centrifugal force, under the same rotational speed and under the same concentric tube 11 diameter, the contained angle can improve the tangential velocity that the oil smoke particle was thrown away from, under oil smoke separator 1, makes the oil smoke particle break away from oil smoke separator 1 inside, improves the separation effect of oil smoke.
The concentric tubes 11 are provided with flow perturbation means 111, the flow perturbation means 111 being connected seamlessly around the end of one end of the concentric tubes 11. The plane of the turbulent flow device 111 is intersected with the middle shaft and has an included angle B, and B is more than or equal to 10 degrees and less than or equal to 135 degrees. The flow disturbance device 111 functions to generate a vortex flow of the soot gas, thereby improving the oil removing capability.
The oil smoke separator 1 is further provided with an eddy current generating device group 14, the eddy current generating device group 14 is fixedly installed on the outer surface of the concentric tube 11 and surrounds the joint of the cornice structure 13 and the concentric tube 11, and the eddy current generating device group 14 is installed on the upper surface of the cornice structure 13. Each group 14 of vortex generating devices consists of one or more vortex generating sub-devices of the same eave structure 13.
The vortex generating device group 14 of the present invention is used for generating vortex for the oil smoke gas, thereby improving the oil removing capability.
The number of the vortex generating device groups 14 is m, m is any positive integer larger than 0, and the m vortex generating device groups 14 are respectively and fixedly installed on the outer surface of the concentric pipe 11 and surround the joint of the eaves structure 13 and the concentric pipe 11.
N =3 in the present embodiment, that is, the concentric tubes 11 in the present embodiment are provided with 3. In the present embodiment, m =2, that is, the vortex generating device group 14 is provided with 2, one is provided in the 3 rd concentric tube, and the other is provided in the 2 nd concentric tube. The number of concentric tubes 11 of the present invention can be any positive integer, and the set of vortex generating devices 14 can be less than or equal to any positive integer number of concentric tubes 11.
The concentric tube 11 is formed by a line segment formed by a plurality of broken lines surrounding the middle axis for a circle, and the intersection position of two adjacent line segments on the inner wall of the concentric tube 11 is a vortex generation position 15. The shape of the concentric tube 11 of the invention has the function of enabling the oil smoke gas to generate vortex on the inner wall of the concentric tube 11 and improving the efficiency of removing the oil smoke.
The eave structure 13 is provided with a plurality of through holes 131. The through holes 131 are used for converging oil particles into large particles when the oil fume separator 1 rotates, so that the oil fume particles are separated from the inside of the oil fume separator 1, and the separation effect of the oil fume particles is greatly improved.
The diameter of one end of the concentric tube 11 is larger than the diameter of the other end. One end of the concentric tube 11 is the end connected with the air draft assembly, namely the air outlet of the concentric tube 11, the other end of the concentric tube 11 is the air inlet of the concentric tube 11, and according to the venturi effect, the larger the area through which the fluid flows, the smaller the flow velocity is, namely, the velocity of one end of the gas concentric tube 11 is greater than that of the other end of the concentric tube 11. According to Bernoulli's law, the higher the speed of the gas, the lower the pressure, so that the pressure at the end of the concentric tube 11 connected with the air draft assembly is high, and the pressure at the air inlet of the concentric tube 11 is low, thereby increasing the pressure difference between the air inlet of the concentric tube 11 and the external environment, so as to promote the oil smoke gas to enter, and improve the oil absorption effect.

The other end of the 1 st concentric tube of this embodiment connects two eave structures 13.
Two eaves portion structures 13 effects of 1 st concentric union coupling have reduced the space volume between 1 st concentric pipe and the 2 nd concentric pipe to reduce the area of the air inlet of the 2 nd concentric pipe, improved gaseous admission speed, increase the pressure differential of 11 inside and exterior spaces of concentric pipe.
The cigarette machine main part is provided with shell 2, convulsions subassembly and oil collecting device 3, and oil smoke separator 1 is rotatory to be installed in the inside of shell 2, and convulsions subassembly fixed mounting just is located oil smoke separator 1's top in the inside of shell 2, and the convulsions subassembly still is connected with the gas outlet, and oil collecting device 3 assembles in the bottom of shell 2.
The housing 2 is provided with a plurality of housing air inlets 21 and a plurality of annular sheets 22 matching with the housing air inlets 21, the annular sheets 22 are integrally connected with the corresponding inner surface of the housing 2 and are positioned at the edge of the housing air inlets 21, the annular sheets 22 are in one-to-one correspondence with the housing air inlets 21, the annular sheets 22 of the present invention can also be fixedly installed on the housing, and the specific implementation is determined by implementation.
The ring-shaped piece 22 functions to generate a vortex when the soot gas enters the housing 2, and to prevent soot particles from being thrown out of the outer space from the housing inlet 21 of the housing 2 when the soot particles are thrown out of the soot separator 1.
The working principle of the range hood is as follows: the range hood is opened, the motor 4 drives the oil smoke separator 1, the wind wheel of the air draft assembly rotates simultaneously, oil smoke particles are separated in seven layers in the range hood, and finally the oil smoke particles are discharged from an almost clean gas outlet. The seven-layer separation is specifically as follows:
first layer separation, inertial separation: lampblack enters the interior of the range hood through the shell air inlet 21 of the shell 2, and enters the annular sheet 22 after entering the shell air inlet 21, because of the pressure difference between the interior of the shell 2 and the external environment and the sudden change of the area of the shell air inlet 21, the air flow speed is accelerated, and the inertia momentum is relatively increased. And the oil smoke will form a very thin boundary layer around the annular sheet 22, and because the outer casing air inlet 21 of the outer casing 2 forms an included angle with the annular sheet 22, the oil smoke is forced to flow upwards and enter the oil smoke separator 1 after flowing downwards along the annular sheet 22, so that the heavier oil separates from the crude oil smoke flow field in the downward inertial motion and moves downwards to be collected in the oil collecting device 3 at the bottom of the outer casing 2, and the first inertial separation is realized.
Second layer separation, vortex separation: the oil smoke particles separated by the first layer further generate flow field separation in the downward and upward flowing direction of the annular sheet 22, and the oil smoke particles cause an unstable flow field under the flow field separation to further form a vortex. The flow field or the vortex flow and the adjacent flow field or the vortex flow are mutually influenced mutually, a continuously rotating flow field is formed on the annular sheet 22, and the rotating vortex flow reaches the maximum vortex quantity. The remaining light oil smoke will not stop at the rotating vortex accumulation of the ring-shaped sheet 22, and when a certain weight is accumulated, the flow field will not support the weight of the oil drop, and will fall downwards or flow along the ring-shaped sheet 22 to the oil collecting device 3.
Third layer separation, centrifugal separation: the eave structure 13 rotates with the concentric tubes 11 to form a centrifugal force that interacts with the attraction of the air extraction assembly. After the second separation, the light oil smoke of remaining part contacts the outermost end of eaves portion structure 13 earlier and gets into concentric tube 11 again when getting into concentric tube 11, and the centrifugal force of eaves portion structure 13 outermost end can leave some fluid or oil smoke particle area or block and get into concentric tube 11 inside and move outward, throws away with higher tangential velocity again, and the particle of throwing away can fall at cyclic annular piece 22, flows to oil collecting device 3 along cyclic annular piece 22 at last.
Fourth layer separation, inertial separation and centrifugal separation: after the third layer of separation, the remaining oil smoke with lighter weight is simultaneously subjected to centrifugal force and attractive force, but the relative attractive force is greater than the centrifugal force. Some of the oil smoke will flow through the through holes 131 to the adjacent eaves 13, and due to inertia, the oil smoke and other oil smoke particles will be gathered into larger oil smoke particles and flow downward, and due to centrifugal force, the oil smoke particles will be thrown out at a higher tangential speed and finally flow along the ring-shaped pieces 22 to the oil collecting device 3.
Fifth layer separation, cyclonic centrifugal force and secondary vortex generation of concentric tubes 11: the inner wall of the concentric tube 11 rotates to form a cyclone, the concentric tube 11 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 rotate without stopping, so that the oil smoke is captured and is not allowed to escape from the pipeline. After the attraction force and the centrifugal force are removed, the oil smoke which continuously rotates from the secondary vortex and moves at the pipe wall in a high tangent mode flows downwards along the inner pipe wall due to gravity and is collected to the oil collecting device 3.
The sixth layer is separated, the spoiler 111 is separated: the flow disturbing device 111 at one end of the concentric tube 11 generates flow field separation on the remaining oil smoke, and the flow field separation can block part of the oil smoke from flowing upwards and capturing the oil smoke by the vortex which does not rotate automatically due to the instability of the flow field.
Separating a seventh layer, and separating a wind wheel by centrifugal force: after the separation of the first six layers, a small amount of very light oil smoke particles are left and sucked into the wind wheel of the air draft assembly due to pressure difference, the rotating wind wheel forms centrifugal force to throw the remaining small amount of oil smoke particles onto the inner wall of the fan, and finally nearly clean gas is discharged outside through the air outlet.
The oil smoke separator 1 of the range hood can be detached out of the range hood and cleaned independently, and can also be detached for maintenance. This oil smoke separator 1 of lampblack absorber produces additional centrifugal force more than prior art's lampblack absorber, can effectively get rid of the oil smoke particle, avoids the oil smoke particle to get into convulsions subassembly, improves the separation effect of oil smoke particle greatly. Meanwhile, the range hood can prevent the air containing the oil smoke particles from contacting with the wind wheel, and the oil smoke particles can be effectively removed from the interior of the range hood.
