The invention provides a ship ballast water filtering system. The system comprises a sea chest, a ballast pump, a flow meter, a filter bypass valve, a filter inlet valve, a filter outlet regulating valve, a filter inlet and outlet pressure difference sensor, an automatic backwashing filter, a filter sewage draining exit automatic switch valve, an outboard discharge port, a ballast tank, a filter backwashing motor, a filter outlet pressure sensor and a filter sewage draining pump. A traditional control method of the automatic backwashing filter is optimized from a single flow control mode to amode of combining the flow of the main pipeline and the outlet pressure of the automatic backwashing filter, the ballast efficiency of the ship and the backwashing effect of the automatic backwashingfilter are both considered, and the operation stability of the ship ballast water filtering system is improved. The invention further provides a ship.
本发明提供一种船舶压载水过滤系统,包括海底门、压载泵、流量计、过滤器旁通阀、过滤器入口阀、过滤器出口调节阀、过滤器进出口压差传感器、自动反冲洗过滤器、过滤器排污口自动开关阀、排舷外口、压载舱、过滤器反冲洗马达、过滤器出口压力传感器和过滤器排污泵,本发明将传统的自动反冲洗过滤器的控制方法由单一的流量控制方式优化成主管路流量和自动反冲洗过滤器出口压力相结合的方式,兼顾了船舶的压载效率和自动反冲洗过滤器的反冲洗效果,提高了船舶压载水过滤系统运行的稳定性。本发明还提供一种船舶。
