Zusammenfassung:	The invention belongs to the technical field of metallurgical sintering and provides a waste heat utilization system for a sinter cooler. The sinter cooler and a waste heat boiler are connected through a smoke inlet and outlet pipeline. Smoke in the sinter cooler enters the waste heat boiler through the smoke pipeline. Steam water in the waste heat boiler is heated through the smoke, so that saturated steam is generated. The smoke enters the sinter cooler again to be used for cooling hot finished sintered ore materials after being cooled. A product steam outlet of the waste heat boiler is connected with an inlet of a steam heat accumulator. The saturated steam enters the steam heat accumulator to be stored in the heat energy form. The saturated steam passing through the steam heat accumulator enters a steam-turbine generator and expands and acts to drive the steam-turbine generator to generate power, and condensed water enters the waste heat boiler again. The heat of the smoke is stored by means of a fused salt heat storage system and the steam heat accumulator, a steam turbine does not need to stop along with the sinter cooler, and the steam temperature change caused by fluctuation of the smoke temperature can be relieved to a certain extent.
