FIELD: dust collection equipment.SUBSTANCE: invention relates to the dry dust collection technique and can be used in chemical, textile, food, light and other industries to clean dusty gases. Two-stage dust collection system with an inertial dust separator includes a housing consisting of cylindrical and conical parts, a dusty gas flow inlet, a dust collecting bin with a mechanical dust removal device, a curtain and a cleaned gas outlet, curtain is made in the form of a chain and at least one continuous protective elements, fixed on a plate suspended on elastic elements to the body, the chain-linking elements are uniformly distributed over the entire area of the passage section of the body and along its length, and the solid barrier element is located with a gap relative to the walls of the body, a layer of a soft vibration damping material is applied to the surface of the body parts, for example VD-17 mastics, moreover, the ratio between the thickness of the metal and the vibration-damping coating is in the
