VORTEX AIR CLEANER Russian patent published in 2005 - IPC

FIELD: physical or chemical processes and apparatus.

SUBSTANCE: vortex air cleaner comprises housing with evacuating chamber provided with one or several separation members each of which consists of separation branch pipes with blade swirlers and outlet branch pipe. The flat blade of the swirlers are interposed between the branch pipes and disks so that the straight outlet edges define inner spaces of the swirlers that have the form of one-space hyperboloids of rotation and are their straight generatrices. The throat periphery of the hyperboloid of the first air swirler is in the space of the disk or in the plane parallel to the disk which is at a distance of the swirler. The throat periphery of the hyperboloid of the second air swirler is in the plane of the disk or plane parallel to the disk and is at a distance of it in the direction opposite to its flowing. The disk of the second air swirler provided with the blades projects out of the separation branch pipe in the direction opposite to the air flow inward to the first separation branch pipe. Before the blade abut against the second separation branch pipe the wall of the second separation branch pipe is provided with rectangular slots for discharging the near-wall air layer with the separated particles to the evacuating chamber.

EFFECT: enhanced efficiency.
