FIELD: devices for filtration of contaminated gas and liquid flows. SUBSTANCE: concentrator is made in form of parallel similar extended fairings secured on two side wedge-shaped bases with periodic system of profiled projections forming wedge-shaped cavity between planes tangent to fairings. Wedge-shaped cavity has rectangular inlet and outlet sections with rounded-off corners. Profiled surface of solid or thin-walled section of fairings ensuring required direction of motion of finely-dispersed inclusions into inner portion of wedge-shaped cavity is formed by elements of lines of exponential function, type $$$, where x is direction along profile of fairings and constant coefficient at $$$, $$$. EFFECT: enhanced efficiency. 6 dwg
