The invention relates to the technical field of waste heat recovery of Bayer process aluminum oxide production, in particular to a seven-effect five-flash condensate water waste heat grading system and an aluminum oxide production device. According to the system, the first-effect condensate water and the second-effect condensate water are divided into two independent loops according to the thought of'temperature alignment and stepped recovery ', namely the first-effect condensate water and the second-effect condensate water, and the condensate water cooled by the two loops finally converges into the same recovery tank and then is pumped back to a boiler or a deaerator. Due to the fact that heat needed by the stock solution, the washing water and the secondary steam condensate water is all borne by original directly-discharged first-effect waste heat and second-effect waste heat, the amount of new steam needing to be supplemented by the evaporator is correspondingly reduced. And meanwhile, the first-effect heat transfer temperature difference of the evaporator is reduced, the system can maintain the seven-effect total temperature difference under the lower new steam pressure, and closed-loop energy saving of replacing new steam with waste heat is achieved.
