CHECKERWORK ELEMENT OF HEAT-AND-MASS EXCHANGE APPARATUS Russian patent published in 2000 - IPC

FIELD: circulating water supply systems; apparatus for heat-and-mass exchange of liquid and gaseous media; elements of sprinklers and water catchers of cooling towers used in industries, power engineering and agricultural complexes; biological cleaning of sewage as carrier for immobilized microflora. SUBSTANCE: checkerwork is made in form of hollow right-angle latticed prism formed by three faces made from polymer threads with rhomboid cells and interweaving; faces of prism are conjugated over cylindrical surface at radius of 5 to 8 mm; distance between lines of conjugation of one face of prism is 40 to 70 mm; ratio of this distance to distance between lines of conjugation of two other faces is equal to (0.7-0.97):1:1 respectively; cross section of prism passing through interweaving of threads includes 7 to 10 of such interweavings. EFFECT: enhanced efficiency. 2 dwg
