AI Technical Summary

Technical Problem

Newly built ships have drinking water pipelines containing special contaminants such as welding slag and grease. Traditional flushing methods have blind spots and the risk of chemical cleaning agent residue. They cannot simultaneously remove biofilm and sterilize, rely on manual experience, resulting in large quality fluctuations and lack of quantitative standards.

Method used

The intelligent new shipbuilding drinking water pipeline flushing device integrates a central controller, a distributed sensor network, a pressurization pump set, a gas-liquid pulse generator, and a dosing device. Combined with sodium hypochlorite solution, it achieves biofilm removal and sterilization through high-frequency pulse waves and automated detection.

Benefits of technology

It improves cleaning effectiveness and automation, reduces human error, ensures reliable rinsing results every time, reduces operating costs and resource consumption, extends equipment life, and enables data-driven optimization decisions.
