The present invention configured as described above not only reduces the fine dust by rotating the fluid to a wider area while rotating, but also selectively sprays snow or cooling water or fresh water to an arbitrary area according to seasons or environmental conditions, and accumulates on the runway. By melting the snow quickly or by cooling the runway heated in summer quickly can be expected to prevent the heat island phenomenon, and to minimize the frictional resistance while maintaining a constant angle during the rotation of the rotor 20 , The snow melt is evenly sprayed along the rotation radius, and is an invention having the effect of preventing damage to the parts by friction.

As mentioned above, although embodiment of this invention was described, those skilled in the art should add, change, delete, or add a component within the range which does not deviate from this invention described in a claim, and this invention. Will be able to variously modify and change, which will also be included within the scope of the invention.
