DEVICE FOR ELECTROOSMOTIC DEWATERING OF WET OBJECT Russian patent published in 2001 - IPC

FIELD: separation of solid and liquid media. SUBSTANCE: device includes electrodes and controllable reversible source of electric energy which outputs are connected to electrodes. One of electrodes is located in dewatered zone. Device is equipped with comparison electrode, transmitter of electrochemical potential, unit of setting of zero potential, adder, potential comparator and command-execution unit. Comparison electrode and transmitter of electrochemical potential are placed near electrode located in dewatered zone, comparison electrode is connected to first inputs of unit of setting of zero potential and adder, transmitter of electrochemical potential is connected to second input of adder, electrode located in dewatered zone is connected to input of unit of setting of zero potential whose output is linked to first input of potential comparator to which second input output of adder is linked. Output of potential comparator is connected to input of command-execution unit which output is connected to controlling input of reversible source of electric energy. EFFECT: optimization of process of change of polarity of electrodes, provision for independence of process from change of external conditions which in its turn raises efficiency of process of electroosmotic dewatering of wet object. 1 dwg
