The utility model discloses a graded energy utilization system used in cement production. The graded energy utilization system comprises an energy supply system and a cement production system. The energy supply system comprises a heating boiler, a back-pressure type generator unit, a back-pressure steam distributing device, dragging steam turbines and dragging steam turbine condensate reflux units. The graded energy utilization system has the advantages that owing to a multi-stage energy utilization mode, shortcomings of high power consumption and production cost and low energy utilization efficiency during common cement production are overcome, waster-heat utilization is further integrated in terms of energy utilization, and the integral energy utilization efficiency is greatly improved.
