4. flow is big in pipeline, cylindrical shell, pressure is high or the situation of other power under can use big blade to be used as power and air inducing, make it can energy savings.

5. each root shoots down pin, shoots down leaf and at a high speed just equaling a layer resistance filter screen effect under the rotation, at a high speed rotation shoots down pin, shoots down leaf in hitting oil smoke or air behind the dust, make it enter pipeline, cylinder inboard wall because action of centrifugal force can be thrown oil smoke or dust away, at pipeline, cylinder inboard wall because the effect of gravity flows into dirt discharge groove, sediment bowl.Also can add wash mill and wash, improve pollution discharge capability, but can not use the object of need drying.

6. many rows shoot down pin, shoot down leaf and just equal the effect of multilayer resistance filter screen, and its density is changeable, can add to shoot down pin, shoot down leaf when rotating speed is low.

7. the density effect that pin is shot down in rotation, the rotating speed that shoots down leaf just equals the resistance screen pack, the speed of its rotation is fast, and the density that just equals the resistance filter screen is big, and the speed of its rotation is slow, and the density that just equals the resistance filter screen is little.

8. it is fixed that the shape of shoot down pin, shooting down leaf also will be come according to the situation of need medium, can make poroid disk pattern when special, oil smoke or the sticking medium that needs, available circle shoot down pin, the little noiselessness of its resistance.

9. dust or the noncohesive medium that needs, shapes such as available polygon, knife-edge shoot down leaf, increase its area that shoots down, therefore have high efficiency of filtration.

10. it is fixed that the mounting means that shoot down pin, shoots down leaf also will come according to the situation of need medium, and it can traverse and places vertically on fixed bar, can also directly be fixedly mounted on the rotor of motor when special.

11. for guaranteeing action of centrifugal force, its rotating speed had better not be lower than 300r/min.For eliminating dead angle, the center of circle, on fixed bar, can add rectifier, little fan blade.

The technical scheme that summary dynamical type filter method is adopted has been introduced and has been guaranteed shooting down pin, shooting down leaf is issued to lower resistance high efficiency filter oil smoke, dusty gas, air etc. in the effect of rotation at a high speed purpose of sparse, multilayer.

The invention has the beneficial effects as follows, can regulate and control filter harmful substances such as harmful substance effect such as oil smoke, dusty gas, air and lower resistance high efficiency filter oil smoke, dusty gas, air, benefit the automatic control of filter effect, rotate at a high speed simultaneously, just resistance is little shoots down pin, shoot down leaf, so can not influence former airflow direction, consumption of power is little, and is simple in structure.
