The specific implementation process is as follows:

when the device is adopted, after the blades 21 rotate along with the rotator 2, the exhaust gas entering the separation chamber 1 from the air inlet 11 can be driven to change from a linear flow field to a curved flow field and then discharged from the air outlet 12, after the exhaust gas moves to change into the curved flow field, oil mist and solid dust in the exhaust gas collide with the inner wall of the separation chamber 1 under the action of centrifugal force of the blades 21 due to heavy weight, the oil mist in the exhaust gas is attached to the inner wall of the separation chamber 1 after colliding with the inner wall of the separation chamber 1, and part of dust is remained in the separation chamber 1 after colliding with the inner wall of the separation chamber 1, so that one-time separation of the oil mist, the dust and the gas in the exhaust gas is realized, and the oil content in the exhaust gas is greatly reduced; and then the exhaust gas continuously enters the filter box 6, the exhaust gas is discharged from the air outlet 61 after passing through the plurality of filter plates 7, and in the process that the exhaust gas flows through the filter plates 7, the screen 72 filters dust in the exhaust gas on one hand, and on the other hand, the screen holes formed by the screen 72 and the through holes arranged on the panel shell 71 enable the exhaust gas to pass through the filter plates 7 and adhere oil mist by utilizing the large-area contact between the filter plates 7 and the exhaust gas, so that the secondary separation of the oil mist, the dust and the gas in the exhaust gas is realized.

Therefore, the two times of interception of the oil mist in the waste gas is realized through the primary separation and the secondary separation, and the probability that the waste gas is pasted with a bag and is difficult to remove dust and ash and the running resistance of the equipment is increased after the waste gas enters the cloth bag dust removal purification equipment is greatly reduced.

In the operation process of the device of the embodiment, the blades 21 in the separation chamber 1 have a boosting effect on the waste gas, the flow speed of the waste gas discharged from the air outlet 12 is higher, the subsequent filter box 6 is more favorable for treating the waste gas, and the problem that the filter plate 7 is frequently replaced due to the fact that oil mist or dust adheres to the filter plate 7 is avoided. And in the process of carrying out oil-gas separation to waste gas, because of pressure difference controller 8 is monitoring the pressure differential between separation chamber 1 and rose box 6 constantly, when pressure difference controller 8 senses that the pressure differential exceeds the setting value, then it is heavier to mean dust or oil mist on the filter 7, has hindered the circulation of waste gas, and jetting control appearance 9 starts this moment for spray tube 201 is to the high-speed gas of filter 7 blowout, realizes the automatic deashing of dust on the filter 7 and handles.

In addition, after the oil mist adheres to the inner wall of the separation chamber 1 and forms oil drops, the oil drops enter the collecting hopper 3 along the inner wall of the separation chamber 1 and finally flow into the oil storage tank 4, when oil needs to be discharged, the oil outlet 41 of the oil storage tank 4 is opened, the collected oil can be discharged, the oil storage tank 4 is arranged to avoid the problem that the oil directly flows to the bottom of the collecting hopper 3, and then the follow-up collection and treatment of dust at the bottom of the collecting hopper 3 are facilitated.

In addition, when the dust or the mixture of the dust and the oil collected in the collecting hopper 3 and the oil collecting hopper 62 is much mixed, the weight valve 202 and the ash discharging valve 5 can be automatically opened, so that the dust or the mixture of the dust and the oil can be automatically and timely discharged.
