UNIT FOR ELECTROCHEMICAL TREATMENT OF WATER Russian patent published in 2001 - IPC

FIELD: electrochemical treatment of water; preparation of ecological activated flushing, disinfecting and sterilizing solutions. SUBSTANCE: proposed unit includes first electrochemical reactor with anode and cathode chambers, starting water supply line, second electrochemical reactor with anode and cathode chambers. All chambers are provided with inlets in lower portions and outlets in upper portions, water supply line connecting the anode chamber of first reactor with cathode chamber of second reactor through intermediate reservoir for letting the reaction medium stand till completion of chemical reactions and catalytic reactor mounted in succession in way of flow of product. Unit is additionally provided with device for control of physico-chemical properties of cleaned water, additional water supply line and cleaned water discharge line. First and second inlets of device are connected respectively with inlet and outlet of chamber of first reactor by additional water supply line and cleaned water discharge line; third inlet of device is connected with outlet of anode chamber of second reactor by other cleaned water discharge line. First and second outlets of device are connected respectively with second and third inlets of device through double valve for simultaneous control of flow sections of lines and third outlet of device is connected with anode chamber of reactor and is used as outlet of two-position water flow selector mounted in device. First inlet of selector is used as first inlet of device; second inlet of selector is connected with cleaned water discharge line before valve; line connects outlet of anode chamber and inlet of cathode chamber of first reactor through hydraulic resistance; outlet of cathode chamber is connected with drainage line. EFFECT: enhanced efficiency. 4 cl, 1 dwg
