Abstract

FIELD: electrolytic processes and equipment. SUBSTANCE: invention relates to replacing anodes when aluminium smelt is subjected to electrolysis with heat recovery. According to invention, new carbon anodes disposed on anode rods are heated using residual heat of anode remainder taken out from fusion and/or from hot fusion material taken out from fusion, whereupon new anodes are brought hot to the fusion. To recover heat and perform heat exchange, multicellular heat exchanger can be utilized. EFFECT: reduced power consumption. 1 dwg

Изобретение относится к способам и устройствам для замены анодов при электролизе расплава алюминия с регенерацией тепла. Согласно изобретению расположенные на анодных штангах новые угольные аноды подогревают с использованием остаточного тепла извлеченных из ванны расплава анодных остатков и/или извлеченного из ванны расплава горячего материала ванны, а затем подают в подогретом виде к ванне расплава. Для регенерации тепла и теплообмена может быть использован теплообменник, состоящий из многокамерной системы.The invention relates to methods and devices for replacing anodes during electrolysis of aluminum melt with heat recovery. According to the invention, the new carbon anodes located on the anode rods are heated using the residual heat of the anode residues extracted from the molten bath and / or the hot bath material extracted from the molten bath, and then fed to the molten bath in a heated form. For heat recovery and heat exchange, a heat exchanger consisting of a multi-chamber system can be used.
