The invention discloses a full-automatic and efficient cleaned aluminum electrolysis cell. The full-automatic and efficient cleaned aluminum electrolysis cell comprises an anode coverage sealing system arranged on a cell shell of the aluminum electrolysis cell, and meanwhile, cooperatively develops a full-automatic aluminum exchange, pole exchange and smoke afterheat recovery system to realize great recovery of lost heat in smoke and efficient centralized treatment of pollutants, so that the operation effects of ultralow electric consumption and ultralow emission are achieved, meanwhile, the workshop staff demands are greatly reduced, the contradiction between huge energy carried by the smoke and shorted smoke recovery methods (low temperature), the contradiction between huge total quantity of the pollutants and difficult treatment of the pollutants due to low concentration, and the contradiction between a lot of manual operations in bad environment and shorted automatic methods are solved, the enrichment of high-temperature smoke and the efficient recovery of the smoke energy in the electrolysis process are realized, the enrichment and the centralized treatment of the pollutants in the smoke are realized at the same time, and finally, the ultrahigh energy efficiency( the energy utilization rate is higher than 70%, and the tonnage aluminum energy consumption is lower than 10000 kWh), the ultralow emission ( the emission of main pollutants (such as PFC) is reduced by above 90%) and the full automation (the workshop staff is reduced by above 80%) in the whole aluminum smelting process can be realized.
