Separating device

Claim 1

A device for separating heavier substances from fluids including liquids or solids from gaseous medium or solids from a liquid medium and wherein the medium is arranged to flow in a flow direction, comprising a housing having an inlet, an outlet spaced from said inlet with a passage between said inlet and said outlet for flow in a flow direction from said inlet through said passage to said outlet, a plurality of horizontally spaced vertically arranged undulated deflecting elements positioned in side-by-side relationship in said flow passage parallel to the flow direction, said deflecting elements each having a plurality of alternating waves and valleys with each wave having an apex and including a plurality of separation chambers defining individual gullies for separating heavier substances from the fluid spaced along the length of each of said deflecting elements on at least one side thereof and including at least one first gully arranged at an apex of one of said waves of said undulated deflecting elements, said gully being defined by a rear gully wall formed by a wall portion of said deflecting element, a downstream wall curved outwardly in an upstream direction from said rear gully wall to form an apex on its exterior and a curved deflection wall on its interior and an upstream wall having the curvature of said deflecting elements extending in a downstream direction outwardly from said rear wall at a location upstream of said downstream wall toward said downstream wall and inwardly of the downstream wall, said downstream wall having a portion overlapping a portion of said upstream wall and being spaced from said upstream wall to define the first gully entrance therebetween, said downstream wall projecting outwardly into the fluid flow and entraining the fluid to flow through said gully entrance so that said deflection wall on its interior deflects the flow into a circular path and imparts a whirling flow to the fluid as it moves into said gully, the whirling flow causing centrifugal separation of the heavier particles in the fluid flow, said deflecting elements including at least one second gully at another apex of said deflecting elements downstream from said first gully and having spaced-apart upstream and downstream parallel boundary walls defining an entrance therebetween larger than said first gully entrance and defining a second gully therebetween extending parallel to the flow direction so as to entrain larger size particles therein which are not entrained by said first gully, said boundary wall interior bordering said second gully being parallel to the flow direction.
