[0024] An electric motor 13 is fixedly provided at the upper end of the fan volute 11, and the output shaft end of the electric motor 13 is transmission-connected to the rotating shaft where the second impeller 12 is located, and the outer surface of the lower end of the second impeller 12 is fixedly connected to the transmission rod 6, so that the rotation of the second impeller 12 can drive the first impeller 7 to rotate together through the transmission rod 6, and the second impeller 12 and the first impeller 7 can be driven to rotate together by the electric motor 13, wherein the rotation of the second impeller 12 can throw out the air inside the fan volute 11, so that a negative pressure is formed inside the fan volute 11, and then the air inside the casing 1 can be replenished into the fan volute 11, and then a negative pressure can be formed inside the casing 1, so that the outside air can be sucked into the casing 1 from the air inlet 2;

[0025] A first collecting plate 14 is fixedly provided at the lower end of the interior of the housing 1, and a second collecting plate 15 is fixedly provided between the guide plates 5. A through hole is formed in the middle of the surface of the second collecting plate 15. The first collecting plate 14 can collect large oil particles remaining at the lower end of the guide plates 5 due to mechanical collision, while the second collecting plate 15 can collect oil thrown out by the centrifugal force due to the high-speed rotation of the first impeller 7.

[0026] The housing 1 is provided with an oil drain pipe 16 on one side of the first collecting plate 14 and the second collecting plate 15. A control valve plate 17 is provided inside the oil drain pipe 16 via a rotating shaft. The oil collected by the first collecting plate 14 and the second collecting plate 15 can be drained through the oil drain pipe 16, and the control valve plate 17 can ensure that the oil drain pipe 16 remains sealed when there is no need to drain the oil.

[0027] A sealed door 18 is provided on one side of the housing 1 through a hinge. The sealed door 18 can be used to quickly open the housing 1 when necessary to perform maintenance and repair operations on all parts inside the housing 1.

[0028] A connection port 19 is fixedly provided between the middle portion of the lower end of the fan volute 11 and the housing 1 , and the fan volute 11 and the interior of the housing 1 can be connected to each other through the connection port 19 to facilitate the flow of air.

[0029] Working principle: When the device is in use, the motor 13 can drive the second impeller 12 and the first impeller 7 to rotate together, wherein the rotation of the second impeller 12 can throw out the air inside the fan volute 11, so that a negative pressure is formed inside the fan volute 11, and then the air inside the shell 1 can be replenished into the fan volute 11, and then a negative pressure can be formed inside the shell 1, so that the outside air can be sucked into the shell 1 from the air inlet 2; and when the oil mist is sucked from the air inlet 2 by the negative pressure, it will collide with the guide plate 5 at the first time, and some larger oil mist droplets and oil particles will be captured on the guide plate 5 due to mechanical collision and retention, and adhere to the guide plate 5, and finally fall onto the surface of the first collecting plate 14 under the action of gravity, and can finally be discharged from the oil drain pipe 16 at the lower end;

[0030] The remaining oil can flow through the through holes along with the airflow and enter the upper end of the second collecting plate 15. When the airflow and oil enter the upper end of the second collecting plate 15, they will come into contact with the high-speed rotating first impeller 7. At this time, the first impeller 7 rotates at a high speed and uses the impeller blades to throw the airflow in all directions. At this time, under the action of centrifugal force, the heavier oil particles in the air can be thrown to the outer surface of the upper end of the inclined guide plate 5, and finally slide down to the upper end of the second collecting plate 15 under the action of the downward force, and then discharged through the oil drain pipe 16 at the upper end.

[0031] Finally, the flue gas that passes through the primary filter screen 9 can enter the honeycomb electric field 3 and the plate electric field 4. After ionization in the honeycomb electric field 3, the charged ions are turned into charged ions. The charged ions are carried to the plate electric field 4 together with the airflow. The collecting electrode plates in the plate electric field 4 are composed of parallel stainless steel plates. Half of these parallel electrode plates are charged with high voltage. Due to the alternating polarity, the charged ions generated are adsorbed on the surface of the plates, thus completing the final fume treatment and collection.

[0032] In summary, the present device is also provided with collision degreasing and centrifugal degreasing before the primary filter screen 9. Both degreasing methods as pre-degreasing means for the primary filter screen do not require frequent maintenance and can effectively reduce the maintenance frequency of the primary filter screen 9. The primary filter screen can even be omitted according to environmental conditions.

[0033] Furthermore, when the device is in use, the first impeller 7 and the second impeller 12 are linked to each other and can be started and used at the same time, without the need for other complex control systems and power transmission systems. The device has low cost, is easy to use, and is easy to promote and use.
