Description
Technical field
The utility model relates to a kind of used for aluminium electrolysis economic structure anode carbon block.
Background technology
Pre-calcining electrolytic cell has and pollutes for a short time, and advantage of low energy consumption now replaced the main equipment that self-baking aluminium electrolytic bath becomes aluminum electrolysis industry, and the capacity of electrolyzer is increasing, and prebaked anode has become the new anode construction of aluminium cell.Prebaked anode possesses the few and low advantage of self pressure drop of the glance coal of generation, prebaked cell for aluminum-reduction is in structure and technologic defective, causing needs regularly clocklike to change anode to keep the continuity of electrolysis production, and prebaked anode can produce out of use anode scrap in the replacing process.In order to reduce cost, just require to reduce the residual content of anode scrap in the industry as far as possible.But because present anode configuration structure design is unreasonable, cause the residue of anode scrap a lot, caused very big waste.
In the prebaked cell Aluminum Electrolysis Production, along with carrying out continuously of electrolysis production, consumed by successive as the anodic pre-baked anode carbon blocks, in order to keep the ordinary production of electrolyzer, must change consumption periodically according to the order of sequence with most anode carbon block.Thereby, change the main daily operation that anode just becomes the prebaked-anode type cell aluminium metallurgy, the consumption costs of anode carbon block has also just constituted a subitem in the Aluminum Electrolysis Production cost.So the height of anode carbon block is directly determining anodic always consumption, anode drop and heat consumption, also affect and change anodic operation coefficient.Therefore, the anode carbon block height exists economy and rational selection problem.
After anode carbon block was increased, along with the prolongation of anode carbon block replacement cycle, the change poles number of times in the unit time reduced, the also relative minimizing with energy expenditure of calorific loss that is caused by change poles.Calorific loss, the anode scrap of opening the ionogen face-piece when supposing change poles identical with the heat that the steel pawl is taken away at every turn, then according to formula: after r=(1-T1/T2) * 100% can calculating anode and increasing 70mm, changing anodic power loss (electric energy expense) decrement is 15.63%.
Through the statistical study actual measurement data, can draw to draw a conclusion: before and after 1, anode was increased, the anode scrap serviceability rate did not have obvious variation.2, the former set(ting)value of anode scrap aspect ratio (165mm) is slightly high, analyze reason and be since actual current efficient a little less than due to the design load 94%.3, the receipts limit integer work difficulty during change poles increases to some extent.Once be difficult to reach standard, change poles needs shaping again after four days.4, by Thoughs is measured statistics, the anode drop after increasing on average increases 11.6mv, and is identical substantially with calculated value.5, after anode was increased, anodic current distributed and to need 22-26 hour just can reach optimum value, postponed 2-4 hour than the electrolyzer that does not add before the high anode.
For the SY350 electrolyzer, the anode carbon block height is increased to 620mm by 550mm, need not transform original equipment, just can satisfy the needs of production and technology.
