ABSTRACT:
The film-type rotary mass-and-heat exchange column comprises a shell which accommodates a vertical shaft carrying the contact stages held in position thereto. The contact stages are formed by the bands curved into the spirals diverging from the shaft and flanged towards the latter at their edges. The bands are provided with longitudinal beads bulging outwards on the concave surface of the bands so as to establish a number of channels adjacent for height.
