The utility model provides a power station waste heat recovery utilizes system, this system mainly collect the hydrophobic lime set and the ding lian sewer of boiler fan heater, heating water heatingthat replace original low pressure steam to give 1# and 2# heat exchange station, and the low temperature lime set that goes out heat exchange station gets into chemical industry oxygen -eliminating device and circulating water pond cyclic utilization more respectively, and secondary flash distillation vapour is retrieved to the top increase steam ejector that the while is linking row flash vesselsurely. Can realize surplus heat resource's cyclic utilization like this, reduce the steam quantity, improving energy efficiency reduces the consumption of unit product water, practices thrift cost and environmental protection. 本实用新型提出种动力站余热回收利用系统，该系统主要将锅炉暖风器的疏水凝液和定连排污水进行收集，代替原来的低压蒸汽给1#和2#换热站的采暖水加热供暖，出换热站的低温凝液分别进入化工除氧器和循环水池再循环利用，同时在定连排扩容器的顶部增加水汽引射器将二次闪蒸汽进行回收。这样可以实现余热资源的循环利用，减少蒸汽用量，提高能源利用率，降低单位产品水的消耗，节约成本和保护环境。
