Abstract:
1. An apparatus for separating entrained particles from a gas flow, said apparatus comprising a housing having an inlet at one end and an outlet at an opposite end; an inlet guide device adjacent to the inlet for causing the gas flow to rotate helically, the inlet guide device being attached to the housing via recesses in the housing adjacent to the inlet; an outlet guide device adjacent to the outlet, and a separating zone between the inlet guide device and said outlet guide device; wherein the outlet guide device comprises a central core and a plurality of guide elements extending outward from the core toward the housing, and the guide elements comprise an angled inlet section matching a helical flow angle of the gas flow; a curved rotation-retarding section for redirecting the gas flow to a linear flow, and a straight discharge section; wherein the angled inlet section forms an angle with the axis of the central core which corresponds to the helical flow angle of the gas flow.
