摘要

Contact tube with lamella comprising a tube (1) of cylindrical shape with external surface of constant or various diameters, inside equipped with a lamella (2) comprising flexible plates (2.1) anchored in a rim (2.2). The tube (1) of cylindrical shape with constant or various diameters of external surface is equipped from one side with long sectioned part with 3 different gradually reducing diameters of cavity and the inlet cavity with the largest diameter passes to the middle cavity conically tapering under 60° angle and the narrowest third cavity is conically ended and from opposite side it comprises a short part starting by a turned inlet under 45° angle and ended by a conical end that is aligned with the centre line of conical end of hollow long part and a different distance occurs between conical ends.
