PREFORMED PACKING FOR HEAT AND MASS EXCHANGE DEVICES Russian patent published in 2014 - IPC B01J19/32 

FIELD: machine building.

SUBSTANCE: preformed packing consists of units made from vertically set corrugated plates having the corrugations with notches formed due to the shift of adjacent corrugation rows in respect to each other, the plates are mounted with a gap in relation to each other in the row of one unit and with a gap in the units adjacent by height for the value commensurable with the corrugations height. The corrugation height amounts to from 0.2 to 0.5 of the value of equivalent channel diameter d_e, and the value of the gap between the adjacent corrugated plates in the row of one unit amounts to from 0.6 to 0.8 of the value of equivalent channel diameter d_e, where d_e=4 ε/a, ε - packing porosity, m³/m³, a - specific surface of the packing, m²/m³.

EFFECT: complete wetting of preformed packing surface, intense turbulisation of liquid phase, high intensity of heat and mass exchange and reduced overall dimensions of a device.
