Abstract

This study aims to introduce the design and optimization of a testing system for the on the slurry pipeline transportation in dredging projects. Due to characteristics of slurries such as high concentration, irregular particles and complex ingredients, slurry transportation often subjects to huge pipe resistance, high energy consumption, pipe blockage and short transportation distance. Literature review indicates that the gas injection to pipeline can effectively improve slurry flow state and reduce pipeline resistance. However, the research on design and optimization of slurry pipeline transportation in dredging projects is scarce. Hence, this study has designed a new air-injected pipeline system for dredging projects. The general structure of the new system and new features of sub-systems have been introduced in details. In the design process, key parameters have been monitored, including the inner pressure, quantity of flow and flow state. These parameters have been used in measurement and control sub-systems, which are suitable for the dredging projects. The optimization and design results demonstrate that the designed air-injected pipeline system are reasonable in design, inclusive in functions and reliable in accuracy and can be applied to simulation of real conditions in slurry translation in dredging projects.
