Abstract
The invention relates to a current collecting bus-bar comprising electrode housings for accommodating a multiplicity of electrodes in electrical contact therewith. Probes for measuring the electric potential locally established in correspondence of the electrical contacts during the passage of electric current are also connected to the bus-bar. The invention further relates to a permanent monitoring system allowing the continuous evaluation of current distribution on each electrode of electrolysis cells of metal electrowinning or electrorefining plants, connected to an alerting system and to means for disconnecting individual electrodes in case on non-compliance with preset values.
Claims11
Current collecting bus-bar for cells of electrochemical plants comprising:
- an elongated main body having homogeneous resistivity, said body comprising housings for one or more optionally removable anode and/or cathode electrical contacts, said housings being evenly spaced apart;
- probes for detecting electric potential, said probes being connected by securing means to said current collecting bus-bar in correspondence of said one or more electrical contacts.
System for continuously monitoring current distribution in each electrode of electrolytic cells of electrochemical plants comprising:
- current collecting bus-bars with housings for one or more optionally removable anode and/or cathode electrical contacts, said bus-bars comprising probes for detecting electric potential connected by securing means to said bus-bars;
- analogue or digital computational means for measuring current intensity values in each individual electrode starting from the electric potential values detected by said probes;
- an alert device connected to each electrode;
- a processor suitable for comparing the current intensity measurement provided by said computational means to a set of predefined critical values for each electrode;
- means for actuating said alert device whenever said current intensity results not compliant to said corresponding predefined critical value for any electrode.
