VORTEX-TYPE DUST COLLECTOR Russian patent published in 2005 - IPC

FIELD: dust collection processes; chemical, textile, food-processing and light industries.

SUBSTANCE: proposed dust collector has cylindrical chamber with dust receiver located in its lower part and axial inlet for dust-laden gas with baffle washer, peripheral inlet for secondary flow and axial branch pipe for discharge of cleaned gas located in upper part of chamber, rotor made in form of body of revolution and mounted along axis of chamber; this rotor is provided with blade mounted on its surface, direction of winding of this blade coincides with direction of rotation of gas. Free end of rotor located in axial inlet performs function of swirler and fairing for primary flow of dust-laden gas. Axial branch pipe used for discharge of cleaned gas is provided with filter element made in form of washer whose outer surface is secured on inner surface of branch pipe. Rotor blade may be provided on side of axial inlet of dust-laden gas only. Axial branch pipe for discharge of cleaned gas has truncated taper surface whose larger base is secured on branch pipe; rotor passes through center of lesser base at spaced relation.

EFFECT: enhanced efficiency of dust collection due to action of revolving flow on field of velocities.
