Alumina distribution in electrolysis cells including inert anodes using bubble-driven bath circulation

摘要: This invention relates to the use of bubble-driven flow enhance dissolution and distribution alumina in an aluminum electrolysis cell operating with inert anodes. By harnessing driving force bubbles rising along sides a sloped anode induce circulation by using group anodes amplify effect, can be maintained close or at saturation without formation muck/sludge. Alumina fed through point feeders specific locations distributed throughout entire rather than sinking bottom below feed location. For given pattern, feeder optimized.
