PACKING FOR HEAT-AND-MASS EXCHANGE APPARATUS Russian patent published in 2001 - IPC

FIELD: cooling water in cooling towers. SUBSTANCE: packing consists of long-cut helical members arranged in modules; each module is hollow and is provided with lattice0like envelope whose cells have ellipsoid or half-round section or sector or segment or polygon or multi-tab figure; direction of turn of helical line is right-hand or left-hand; axis of turn of helical line intersects figure of helical member profile or does not intersect it; members are arranged in module in horizontal, inclined or vertical rows, with or without gaps in rows, at similar figures of profile or their combination, at similar or combined direction of axes, with pitch of helical lines of adjacent members coinciding or not coinciding. EFFECT: enhanced efficiency of crushing water sprays and cooling of water. 3 dwg
