Abstract
Abstract An apparatus and method for separating material which includes solid and/or particulate matter from flowing liquid and/or gas. The apparatus includes a separation panel positioned in a fluid flow path, and the separation panel is housed in a separation chamber. Fluid can be introduced into the separation chamber by an inlet to establish a circular flow of the fluid within a confine of the separation panel, so material entrained in the fluid is trapped within the confine of the separation panel. The separation panel, separation chamber and inlet can be dimensioned and disposed such that as the apparatus operates, the flow of the fluid outside the separation panel is in a direction opposite to a direction of the flow of the fluid within the separation panel. The separation panel can include plural deflection means for deflecting material entrained in the fluid away from the openings, and the deflection means are generally opposed to a direction of the flow of the fluid, each opening having one of the deflection means associated therewith.
