ABSTRACT:
A device for separating particulate matter from a fluid in which such particles are dispersed by causing the fluid to flow longitudinally through a conduit of uniform cross-section and in which a plurality of elements are disposed, with the first of the elements being disposed at an input end of the conduit and sealed against the inner wall thereof. The fluid is caused to flow through the conduit at a velocity such that the particles are fluid-borne. The remainder of the elements are offset laterally inward of the conduit wall by a distance which increases as a function of each element's numerical position after the first element and they are equally spaced apart in a longitudinal direction to provide a gap between successive pairs thereof. Each element, except for an outtake orifice, includes an inner surface disposed at an oblique angle with respect to the longitudinal axis of the conduit. The lateral offset of the elements is such that an outer portion of each downstream element is partially shaded from direct exposure to the longitudinal fluid flow within the conduit. The orientation of successive elements being such that the unshaded or exposed inner edge portions of the obliquely oriented surfaces serve as deflecting regions for the particle laden fluid flow. The deflecting region of each element is generally a non-convex surface and the shaded portion of each element, following the first one, serves as a separating region and with the gap between successive elements provides for the outflow of gas from the inwardly deflected flow. The outtake orifice includes an upper surface that defines the peripheral edge of the orifice which is disposed generally in axial alignment with an innermost edge of the deflecting region of the last of the elements for removing the deflected flow from the conduit.
