Based on a ship at least comprising two generators and a steam turbine, the ship waste heat recovery device comprises a cooling water channel, two heat exchangers and a control valve bank, the cooling water channel is provided with two cooling water inlets and two cooling water outlets, the cooling water inlets are communicated with cooling systems of the ship generators respectively, and the two heat exchangers are communicated with the control valve bank. The cooling water outlet is communicated with the heat exchangers, one heat exchanger exchanges heat between the cooling water and a water inlet pipe of the ship water heater so as to preheat water in the water inlet pipe, and the other heat exchanger exchanges heat between the cooling water and condensate water so as to change the condensate water into steam to be supplied to the steam turbine; the invention further discloses a waste heat recovery method. And the use scene of heat recovery can be selected, so that the effects of energy conservation and emission reduction are achieved.
本发明公开了一种船舶废热回收装置,基于至少包括两个发电机和蒸汽涡轮的船舶,包括冷却水通道、两个换热器以及控制阀组,冷却水通道具有两个冷却水进口和两个冷却水出口,冷却水进口分别连通船舶发电机的冷却系统,冷却水出口接通换热器,一个换热器将冷却水与船舶热水器的进水管进行热交换从而对进水管中的水预热,另一个换热器将冷却水与冷凝水之间进行热交换从而使冷凝水变为蒸汽供给蒸汽涡轮;还公开了其废热回收方法。可选择热量回收的使用场景,达到节能和减排的效果。
