FIELD: construction. ^ SUBSTANCE: there is a case of a pipe, drum or tower, in which there is one or more diverters, each of which consists of even number (not less than 4) of conical cavities at an angle. All the cavities meet at the middle point on the axis of the diverter, which is also the centre of the diverter. The point of intersection of axial lines of odd and even conical cavities are located, respectively, on each lateral face and symmetrical to each other. Each conical cavity consists of two lateral quadrangular surfaces and outer surface, formed by a curvilinear surface or curved plain surface, as well as a sector inner surface. The outer contour of the three dimensional crossed diverter is interfaced with the inner wall of the case of the pipe, drum or tower. In that case, the upper or lower inner contour lines divide the cross-section of the pipe, drum or tower from both sides of the three dimensional crossed diverter on the central zone and peripheral zone. ^ EFFECT: increased effectiveness of thermal and mass transfer. ^ 8 cl, 3 dwg |
