DUMPED PACKING FOR HEAT- AND MASS-TRANSFER APPARATUSES Russian patent published in 2003 - IPC

FIELD: packings of heat- and mass-transfer apparatuses for systems of gas(vapor)-liquid; applicable in column apparatuses for conduction of processes of absorption, desorption, rectification and drying or cleaning of gases in chemical, gas, petrochemical and allied industries. SUBSTANCE: dumped packing from sheet material contains installed at angle to one another bulk members of arc profile interconnected by partition. Sheet billet is made in form of tetragon. Arc profiles are made in form of cylindrical, conical or polyhedral spiral. Partition is corrugated and made in form of blade. EFFECT: intensified flows of processes of heat- and mass-transfer due to improved distribution of gas and liquid flows and increased surface of contact, simplified design and reduced increased surface of contact, simplified design and reduced lasses of material in its cutting from sheets and strips. 3 cl, 7 dwg
