METHOD OF CONTINUOUS COUNTERCURRENT RUNNING OF HYDROMECHANICAL HEAT-MASS-EXCHANGING PROCESSES IN MOVABLE DENSE LAYER OF DISPERSION Russian patent published in 1996 - IPC

FIELD: chemical industry. SUBSTANCE: method allows to increase rate of processes running in heterogeneous mediums due to their running by continuous method in conditions of countercurrent contacting dispersion in the form of highly concentrated (up to 85 %) suspension layer and dispersion medium. Liquid state of highly concentrated suspension, in spite of gravitation force action direction, is provided due to periodical pseudoliquefaction by unidirectional pulses of dispersion medium counter flow with speed close to speed of pseudoliquefaction. Process rate increase and more effective usage of column apparatus is also provided by feeding of solid dispersion in the form of deluted ( to 10 % ) suspension in removing from column apparatus and circulating dispersion medium. Action on highly concentrated suspension layer by unidirectional pulses and feeding of homogenized in dispersion medium dispersion into apparatus increases efficiency of apparatus volume unit usage by 12 - 15 % as apparatus operational volume is filled by 85 %. EFFECT: increase efficiency. 2 cl, 1 dwg
