Furthermore, an access door is arranged on the air inlet chamber. The maintenance is convenient.

The utility model has the advantages that:

1. the utility model discloses the use of well device makes the batting dust that enters into the fume purification device the inside reduce 95%, and fume purification device's clearance frequency reduces to about original 1/6. The oil fume purification device can not generate hidden troubles such as fire.

2. The utility model discloses well rotary filter can not need special shut down the clearance through jet-propelled and water spray self-cleaning filter screen.

3. The utility model discloses the setting of well minor arc baffle can avoid the sediment water of arranging slag notch department to get into the air-out cavity.

4. The utility model discloses the cross-section of well circular filter screen is greater than the cross-sectional area of air intake, has guaranteed the smooth and easy of entire system ventilation, can not influence entire system's the efficiency of airing exhaust.
