METHOD AND DEVICE FOR CONTROL OF INTERFACE BETWEEN TWO SEPARABLE SOLUTIONS AND AERATION PREVENTION UNIT Russian patent published in 2002 - IPC

FIELD: liquid extraction technique. SUBSTANCE: method consists in control of height of heavier aqueous solution by passing separated aqueous solution upward through tubular elements. In this case, height of tubular elements is controllable. To avoid aeration of aqueous during their removal from separation module, solution are passed through closed nozzle-like water-measuring chests provided with overflow; these chests are deeper than unloading end. Solution interface control unit includes separator whose unloading end is provided with chute for discharge of organic phase; its upper end is mounted at constant height in way of liquid flow; it is also provided with water outlet for discharge of solutions from separator. Water outlet is provided with vertical tubular elements located inside this outlet. Height of tubular elements is adjustable; their upper edge is edge of overflow. Besides that, provision is made for prevention of aeration during discharge of two solution from separator whose solution extraction chute and water outlet are connected with nozzle-like water-measuring chest located deeper as compared with this chute and water outlet. Bottom portion of chest is connected with solution carrying pipe line. EFFECT: possibility of monitoring flow of solution being separated. 13 cl, 10 dwg
