Abstract
The maximum acceptable operating current of an electrode immersed in an electrically conductive liquid is increased by providing at least one shield member in front of the electrode and serving to reduce the current density at the part or parts of the electrode where current density would otherwise be highest.
Claims12
Electrical apparatus comprising:
- an electrode and a counter electrode, each having an area exposed for current flow;
- flow path means for defining a flow path of a liquid through said electrical apparatus and over said electrode and counter electrode;
- and
- shield means for increasing the current carrying capacity of the electrode and counter electrode by reducing current density at parts of the electrode surface and counter electrode surface which in the absence of the shield means would experience the highest current density;
- said shield means comprising at least one shield member in a fixed relationship with the electrode and counter electrode, said at least one shield member being thin relative to the length of the current path in the electrical apparatus.

Electrical apparatus comprising:
- an electrode and a counter electrode, each having an area exposed for current flow;
- flow path means for defining a flow pat of a liquid through said electrical apparatus and over said electrode and counter electrode;
- said flow path means comprising a tubular member having a plurality of said electrodes disposed in a longitudinally spaced relationship along an internal surface of said tubular member, and a corresponding plurality of said counter electrodes, facing said electrodes, also disposed in a longitudinally spaced relationship along the internal surface of said tubular member;
- shield means for increasing the current carrying capacity of the electrode and counter electrode by reducing current density at parts of the electrode surface and counter electrode surface which in the absence of the shield means would experience the highest current density;
- said shield means comprising a plurality of shield members fixedly disposed between each electrode and its respective counter electrode in a space, generally face to face relationship with an edge region of the electrode area exposed for current flow;
- said shield member being thin relative to the length of a current path in the electrical apparatus.

Electrical apparatus comprising,
- an electrode and counter electrode, having an area exposed for current flow;
- spacer means for maintaining the electrode and counter electrode in a spaced relationship;
- containing means for containing a liquid to occupy the space between the electrode and counter electrode such that the liquid extends laterally beyond edge regions of the areas of the electrode and counter electrode exposed for current flow;
- passing means for passing said liquid through said containing means to flow over said electrode and counter electrode;
- and
- an electrically insulated shield member fixedly disposed between the electrode and the counter electrode in a spaced, generally face to face relationship with said edge regions of the areas of the electrode and counter electrode exposed for current areas of the electrode and counter electrode exposed for current flow;
- said electrically insulated shield member partially obstructing the passage of electric current at said edge regions of the electrode and counter electrode exposed for current flow.
