Abstract: The proposed heat-mass exchange system comprises a housing (1) with plates on whose blade are arranged turbulence contact elements comprising: a coaxially mounted cylindrical shell (4) with apertures (5) in the lower section and vertical slits (6) in the upper section; baffle (10); an overflow pipe (7); and a swirl vane (12). The novelty of the proposed heat-mass exchange system is the design of the blade in the form of a set of upwardly flanged shelves (2) along whose longitudinal axis are mounted a series of turbulence contact elements, while grooves (8) are fashioned around the circumference of the lateral edges underneath the intake sections of the overflow pipes (7) mounted therein; the blade of the plates is provided with longitudinal plates (3) secured between the flanges of the shelves (2) and in the grooves (9) formed in the intake sections of the overflow pipes (7) which protrude above the blade, while the longitudinal axes of abutting shelves (2) intersect at right angles.
