Field of the Invention The present invention relates to a centrifugal type oil mist precipitator, and more particularly, to a centrifugal type oil mist cleaner capable of quickly and accurately centrifugally separating and collecting oil mist such as cutting oil generated in an industrial field.

In general, an oil mist precipitator is used to prevent oil mist generated in the course of cutting, polishing, cleaning, or cooking in an industrial field from spreading to the surroundings.

The oil mist precipitator sucks the gas mixed with the oil mist through a pump or the like, and the oil mist contained in the gas stream is collected by a filter (filter medium) made of paper or fiber, which is a porous material, .

However, in the conventional oil mist dust collector constructed as described above, maintenance and maintenance due to replacement or cleaning of the dust filter are very cumbersome and the maintenance cost increases, and industrial waste due to the dumped dust filter is mass-produced.

Accordingly, Utility Model No. 0418713 discloses a technique for easily separating air and oil using a centrifugal separator in order to solve the above problems.

In the Utility Model No. 0418713, an oil mist dust collector is provided with a swirl type fan for centrifugal separation of the oil mist.

However, in the conventional oil mist dust collector as described above, since the oil mist containing air is caused to hit the swirl-type fan rotating by the motor, the oil mist is guided to the outside, so that the frictional resistance between the gas and oil mist and the swirl- Flow is difficult to be performed, and therefore, the air permeability and treatment performance are deteriorated.

Since the vortex does not occur at the central axis portion of the vortex-type fan, the dust collecting performance or efficiency is lowered.
