The minimum distance between the oil fume separator 1 and the shell 2 is defined as F, and F is more than or equal to 2mm and less than or equal to 100mm.
The main body of the range hood is also provided with an air draft component and an oil collecting device 3, the air draft component is fixedly arranged inside the shell 2 and positioned above the oil smoke separator 1, the air draft component is also connected with the air outlet, and the oil collecting device 3 is assembled at the bottom of the shell 2. The air draft assembly is provided with a fan, a wind wheel and a volute, the fan is assembled inside the volute, the wind wheel is in transmission connection with the fan, and the shell is fixedly installed inside the shell 2 and located above the oil smoke separator 1. The shell 2 is a sphere structure.
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, as shown in fig. 8. The seven-layer separation is specifically as follows:
first layer separation, inertial separation: the oil smoke enters the interior of the range hood through the shell air inlet 21 of the shell 2, and the oil smoke 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 ring-shaped sheet 22, and because the outer shell air inlet 21 of the outer shell 2 forms an included angle with the ring-shaped sheet 22, the oil smoke is forced to flow upwards and enter the oil smoke separator 1 after flowing downwards along the ring-shaped sheet 22, so that the heavier oil moves downwards separately from the crude oil smoke flow field in the downward inertial motion and is collected in the oil collecting device 3 at the bottom of the outer shell 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 of the annular sheet 22 and accumulate, 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 annular sheet 22 to the oil collecting device 3.
Third layer separation, centrifugal separation: the rotation of the eave structure 13 following the concentric tubes 11 creates a centrifugal force that interacts with the attractive force of the wind wheel. 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 to the adjacent eaves structure 13 through the through holes 131, 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 the oil smoke particles will be thrown out at a higher tangential speed due to the centrifugal force effect and finally flow to the oil collecting device 3 along the ring-shaped pieces 22.
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. When the attraction force and the centrifugal force are removed, the continuously rotating secondary vortex and the oil smoke which moves at the pipe wall in a high tangent line flow downwards along the inner pipe wall to be collected in the oil collecting device 3 due to gravity.
The sixth layer is separated, the spoiler 111 is separated: the turbulence device 111 at one end of the concentric tube 11 generates flow field separation on the remaining oil smoke, and by means of the flow field separation, part of the oil smoke is blocked by instability of the flow field and does not flow upwards or capture the oil smoke by a self-rotating vortex.
Seventh layer separation, wind wheel centrifugal separation: after the first six layers of separation, a small amount of very light oil smoke particles are left to be 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 oil smoke separator-containing range hood of the range hood with the oil smoke separator has small volume, so that the volume of the range hood can be flexibly adjusted. Meanwhile, the lampblack absorber with the lampblack separator can prevent air containing lampblack particles from contacting with the wind wheel, and lampblack particles can be effectively removed from the interior of the range hood.
Example 2.
The utility model provides a take lampblack absorber of oil smoke separator, other characteristics are the same with embodiment 1, the difference lies in: the maximum diameter D of the soot separator 1 is 250mm.
This embodiment is littleer than the oil smoke separator 1 maximum diameter of embodiment 1, and the volume size flexibility of this lampblack absorber is bigger.
Example 3.
The utility model provides a take lampblack absorber of oil smoke separator, other characteristics are the same with embodiment 1, the difference lies in: n =4 in the present embodiment, i.e., 4 concentric tubes 11 in the present embodiment are provided. In the present embodiment, m =2, that is, the vortex generating device group 14 is provided with 2, one is provided in the 4 th concentric tube, and the other is provided in the 3 rd concentric tube. While the concentric tubes 11 of this embodiment correspond one-to-one to the eave structure 13.
