Device for separating suspended matter (2.2) from gas streams (2; 2.1) with streaming gases (4; 7), the device comprising: - at least one collection device surrounded by a wall (3.1), tapering in the direction of flow of the gas streams for gas streams loaded with suspended matter (2.2), - at least one zone adjoining in the direction of flow, for producing at least one compressed gas stream (2.1) loaded with suspended matter (2.2), as well as - at least one agglomeration zone (4.1) for forming condensates, aggregates and/or agglomerates (4.2) of the suspended matter (2.2), characterized in that the device further comprises: - at least one pair of high-pressure gas curtains (4a; 4b) flowing laminarly against each other at an angle α perpendicular to the direction of flow of the at least one compressed gas stream (2.1) loaded with suspended matter (2.2), colliding at an angle β along a line of incidence (4.4), as a barrier for the at least one compressed gas stream (2.1) loaded with suspended matter (2.2) to form at least one agglomeration zone (4.1) for condensation, aggregation and/or agglomeration of the suspended matter (2.2), wherein (i) the device comprises, for the generation of at least one pair of the laminar high-pressure gas curtains (4a, 4b), at least one pair of opposite devices (4a.4; 4b.4) each with an outlet nozzle (4a1; 4b1), a flow channel (4a3; 4b3) for the gas flowing laminarly in the direction (4a7; 4b.7) and a plug-in connection (4a.6; 4b.6) accommodated in a receiving part (4a5; 4b.5) for connecting a compressed-gas line to the device (4a.4; 4b.4), wherein (ii) the latter are each plugged into the opposite outer walls (3.1) of the device by means of a form-fitting plug-in part (4a.2; 4b.2) with integrated flush bearing part, wherein (iii) the colliding high-pressure gas curtains (4a; 4b) have the same velocity, the same pressure, the same length and the same temperature, wherein (iv) the angle of incidence β of the high-pressure gas curtains (4a; 4b) ranges from 90° to 170° and wherein the exit angles α of the high-pressure gas curtains (4a; 4b) range from 30° to 80°, - at least one discharge line extending directly in front of the lower edges of the colliding high-pressure gas curtains (4a; 4b) for the condensed, aggregated and/or agglomerated suspended matter (4.3) formed in the agglomeration zone (4.1), wherein at least one diaphragm, which extends obliquely upwards towards the high-pressure gas curtains (4a; 4b) and parallel to the base line of the high-pressure gas curtains (4a; 4b) and partially covers the opening of the at least one discharge line, is present, as well as - at least one discharge line for the purified gas streams (4.2) loaded with little suspended matter or not loaded with suspended matter (2.2). - at least one collection device surrounded by a wall (3.1), tapering in the direction of flow of the gas streams for gas streams loaded with suspended matter (2.2), - at least one zone adjoining in the direction of flow, for producing at least one compressed gas stream (2.1) loaded with suspended matter (2.2), as well as - at least one agglomeration zone (4.1) for forming condensates, aggregates and/or agglomerates (4.2) of the suspended matter (2.2), - at least one pair of high-pressure gas curtains (4a;
