REGULAR PACKING FOR HEAT- AND MASS-EXCHANGER APPARATUS Russian patent published in 2002 - IPC

FIELD: processes of rectification, absorption, cleaning and drying of natural gases, as well as mixing of liquid and gas flows, separating phases in separating units, performing function of contact element in mixing condensers; all technological processes of oil and gas industry. SUBSTANCE: proposed packing consists of vertical corrugated sheets whose projecting corrugations are brought in contact; each corrugation is made with inversely concave elements which are located at points of intersection of parallel lines with edges of corrugations. Transversal notches are made on corrugations along parallel lines at points of intersection with edges of corrugations; inversely concave elements in form of trapezia which are so bent line of bent lies on inversely concave edge of corrugation are found between each pair of notches. Corrugations along parallel lines at points of their intersection with fins of corrugations are provided with transversal notches; inversely concave elements in form of triangles whose bases are equal to length of notches and vertices located on edges of corrugations are made at each notch; they are so bent that lines of bend lie on inversely concave edges of corrugations; notches with inversely concave elements are also made on corrugations on back side of sheet. Parallel lines intersecting the edges of corrugations at point of location of inversely concave elements are located at angle of 60 to 90 deg. relative to edge of corrugations. Perforated sheets or gauzes are mounted between corrugated sheets; sizes of their meshes ensure continuous flow of liquid. EFFECT: enhanced efficiency of mass and heat exchange due to turbulization of flows inside layer of packing. 3 cl, 7 dwg
