The outside of the wind turbine is equipped with shroud upper panel, has gap between the front end of the filtering net cylinder and shroud upper panel.
Compared with prior art, the utility model has the advantage of：It can be increased using the filtering net cylinder of stereochemical structure
For surface area when oil smoke passes through oil smoke separate mesh, the linear velocity of filtering net cylinder rotation is higher, and oil droplet is by the peripheral surface of filtering net cylinder
The probability of impact interception increases, and improves the effect of oil smoke separation, and staying in the drop on filtering net cylinder surface can flow and assemble, when
The centrifugal force that drop is subject to can throw away filtering net cylinder, therefore oil droplet is not easy to plug mesh after being more than skin-friction force.Oil smoke first from
The filter mesh on filtering net cylinder surface enters in filtering net cylinder, is entering in impeller, and the space in filtering net cylinder can play
Flue gas drainage effect, meet air fluidics, when oil smoke pass through filtering net cylinder when and filtering net cylinder between generate noise inside
Reduce ear-piercing howling.
Filtering net cylinder includes evagination net and indent net again, and overall volume is smaller, and rotational stabilization is good, during operation, oil smoke into
Before entering impeller, dynamic filtration of evagination net ecto-entad is first passed through, then oil smoke is flowed again from inside to impeller direction, is passed through
Therefore the secondary dynamic filtration of indent net, although single layer filter wire side, can realize mistake of the oil smoke by Dynamic Networks twice
Filter, filter effect are further promoted.
