According to the marine main engine high-temperature water recovery system, in the system, the air cylinder and the air cooler in the main engine are arranged in parallel, the temperature or flow of high-temperature water flowing to the water making machine can be increased, namely the available heat of the water making machine is increased, and therefore the fresh water yield is increased; secondly, a waste gas economizer, a first heat exchanger and a second heat exchanger are arranged in the recovery system, heat in main engine waste gas and heat in generator waste gas are effectively utilized, the waste heat utilization rate is increased, and the fresh water yield can be increased; in addition, the main machine preheater is additionally arranged between the water making machine and the main machine, the temperature of high-temperature water entering the water making machine can be increased, and the yield of fresh water can also be increased. And finally, through unique pipeline design and application of a controller to adjust pipeline connection, various working modes can be achieved, and the production requirement is met.

    本发明提供一种船舶主机高温水回收系统,在该系统中,主机中的气缸和空冷器并联设置,有助于提高流向制水机的高温水的温度或流量,即制水机可利用的热量增加,从而增加淡水产量;其次,本发明通过在回收系统中设置废气经济器、第一换热器和第二换热器,将主机废气中的热量及发电机废气中的热量有效利用,提高了废热利用率,有助于增加淡水产量;另外,在制水机与主机之间增设主机预热器,能够提高进入制水机中的高温水的温度,同样能够提高淡水产量;最后,本发明通过独特的管路设计,以及运用控制器对管路的连接进行调整,从而能够实现多种工作模式,满足生产需要。
