MULTIPLE-CHAMBER COORDINATED VORTEX-TYPE APPARATUS Russian patent published in 2000 - IPC

FIELD: vortex acoustic dispersion equipment used in coal, food-processing and other branches of industry. SUBSTANCE: apparatus has inlet and outlet branch pipes and cylindrical vortex chamber between them, and is further equipped with auxiliary vortex chambers and auxiliary branch pipes between them. All chambers are made alike and arranged in spaced relation, with space between them being calculated from formula: d=(12.8-13.3) R n, where R is radius of each chamber; n is whole number, n=1,2,3,... Such construction provides multiple-staged conversion of kinetic energy of working fluid into vibrational energy (with gradual reduction downstream of working fluid flow), on condition that operation of vortex chambers is coordinated. EFFECT: increased efficiency and simplified construction. 1 dwg
