PACKET-TYPE VORTEX PACKING FOR HEAT-AND MASS-TRANSFER APPARATUSES Russian patent published in 2003 - IPC

FIELD: designs of packet-type packings for heat-and mass- transfer apparatuses applicable in conduction of process of absorption, desorption, wet-type dust collecting chemical, petrochemical, power, metallurgical and other allied industries. SUBSTANCE: packet-type vortex packing consists of many similar rectangular cells interconnected into a single packet. In this case, walls of each cell are displaced relative to one another in vertical to cover frontal slot at cell inlet owing to lengthened and bent inside ends forming vortex generator. Ends of both wall at outlet of gas flow from cell are also lengthened and bent inside cell to cover frontal slot end to form the second vortex generator. Surface of each cell is fully or partially having regular roughness and/or perforation of any shape. EFFECT: higher efficiency of operation of heat- mass-transfer apparatus with low power consumption. 2 cl, 4 dwg
