SYSTEMS AND METHODS FOR PROTECTION OF ELECTROLYSER SIDE WALLS Russian patent published in 2018 - IPC C25B9/00 C25B15/00 C25C7/00 

FIELD: electricity.

SUBSTANCE: electrolyser comprises the following: an anode, a cathode spaced from the anode, a molten electrolyzing bath in fluid communication with the anode and cathode. The molten electrolyzing bath has a chemical composition of a bath comprising at least one bath component, a housing having a bottom and at least one side wall surrounding the bottom. Herein the electrolyser housing is designed to hold the molten electrolyzing bath. The side wall essentially consists of said at least one component of the bath, wherein the side wall further comprises the following: the first side wall part adapted to be mounted on a heat insulating lining of the side wall and holding the electrolyte and the second side wall part formed protruding upward from the bottom of the electrolyser housing. Wherein the second side wall part is longitudinally spaced from the first side wall part, so that the first side wall part, the second side wall part and the base between the first part and the second part form a trough. The trough is configured to receive and hold a protective precipitate separately from the electrolyser bottom. The protective precipitate can dissolve from the trough into the molten electrolyzing bath so that the molten electrolyzing bath has a level of said at least one bath component that is sufficient to maintain the first side wall part and the second side wall part in the molten electrolyzing bath.

EFFECT: elements of the electrolyser side wall allow protecting the side wall from the electrolyzing bath.
