摘　　要：针对某案例电厂的实际运行情况,充分利用现场原有资源,制定1套综合回收方案。乏汽采用使用方便、不耗用电能的汽汽引射器(蒸汽喷射式热泵)进行回收;采用热水泵抽取热水并送至换热系统,对热水的余热及冷却后的除盐水分别进行回收。方案能够对定排部分的可回收资源给予充分合理回收及利用,且投资费用相对不高,改造收益显著。According to the actual situation of the power plant in the case, make full use of the original resources on site and formulate one set of comprehensive recovery plan. The lack of steam is recycled by steam ejector(steam injection heat pump) which is convenient to use and does not consume electric energy. The hot water is pumped by a hot pump and then sent to the heat exchange system. The waste heat of the hot water and the desalinated water after cooling are recovered respectively. The scheme can fully and reasonably recover and utilize the recyclable resources of the fixed drainage part, and the investment cost is relatively low, and the transformation income is significant.
