FIELD: chemical engineering. SUBSTANCE: invention concerns attachments for heat/mass-exchange apparatuses which may be used in processes with contact interaction of phases, chiefly for separation of drop liquids from gas-liquid stream. Attachment contains a packet of flat multiturn wire spirals fastened between grooves. The latter have holes through which narrow sides of turns are passed to form loops fixed on the outer side with common rod fastener. Flat wire spiral can be made with bifilar winding, while spirals in adjacent rows are installed with their winds shifted in checkered order. EFFECT: improved design. 3 cl, 2 dwg
