Background

At present, a large part of offshore ships in China adopt evaporative single-cylinder diesel engines, and the diesel engines are cooled by means of evaporation of cooling water in a water tank, so that a large amount of cooling water needs to be added in the running process. The particularity of offshore operation makes carrying and replenishing of fresh water difficult, so that seawater with high salinity is generally adopted to replace fresh water to enter a cooling system of a diesel engine for cooling. When the ship sails on a shallow channel or near shore, water containing silt and debris is pumped into the diesel engine heat exchanger through a water pump, and the silt is adsorbed on the pipe wall or blocks the water pipe, so that the heat exchanger fails. The existing heat exchange device cannot timely clean impurities such as silt in a pipeline.
