FIELD: cleaning of dust-separating devices. SUBSTANCE: devices for mechanical self-cleaning of aerodynamic modules, involving an inlet forming cone and an aerodynamic concentrator in the form of cone-or wedge-convergent system of rings, plates or conical spiral with slots, have flexible laminated cleaning members with cutting edges, whose profiles coincide with profiles of the slots, located in the slots and installed for vibration on a string or rod. The method of mechanical self- cleaning of aerodynamic dust-separating module provided with an aerodynamic concentrator of the above type involves rotation of the concentrator relative to laminated cleaning members, or their movement relative to the concentrator; the cleaning members are subjected to vibration. EFFECT: facilitated procedure. 9 cl, 21 dwg
