The invention provides a ballast tank anti-freezing system and method based on a diesel engine cooling sea water pump. The ballast tank anti-freezing system comprises a PLC control system, a central cooler, a main sea water pump and a diesel engine cooling loop system. In the low-temperature working condition sailing process, in order to prevent the ballast tanks from being frozen, the main seawater pump connects ballast water of each ballast tank into the central cooler to exchange heat with the diesel engine cooling loop system, on one hand, the ballast water is heated to prevent the ballast tanks from being frozen, on the other hand, heat of the diesel engine can be taken away, and continuous and stable operation of a power system is guaranteed; when the temperature of seawater cannot cause freezing of the ballast tank, the main seawater pump takes water from the ocean to cool high-temperature cooling water of the diesel engine cooling loop system, so that continuous and stable operation of the diesel engine is ensured; the ballast water does not participate in heat exchange, so that the service life of the ballast tank coating is prevented from being influenced by overhigh temperature of the ballast water.

    本发明提供了一种基于柴油机冷却海水泵的压载舱防冻系统以及防冻方法,压载舱防冻系统包含有PLC控制系统、中央冷却器、主海水泵、柴油机冷却回路系统。在低温工况航行时,为了避免压载舱结冰,主海水泵分别将每个压载舱的压载水接入中央冷却器与柴油机冷却回路系统进行换热,一方面为压载水进行升温避免压载舱结冰,另一方面可以带走柴油机的热量,保证动力系统的持续稳定运行;当海水温度不会导致压载舱结冰时,主海水泵从海洋取水来为柴油机冷却回路系统的高温冷却水进行降温,从而保证柴油机的持续稳定运行;由于压载水不参与换热,避免压载水水温过高影响压载舱涂层寿命。
