Abstract

In order to improve the economic efficiency of coal transportation in Shenwei pipeline and reduce the investment cost. According to the location characteristics of Shenmu head end pulping plant, it is convenient to take hongliulin mine water, and it can be considered as the second water source. This paper mainly compares the changes of water quality indexes before and after Fugu water and hongliulin mine water are used as coal handling water, and analyzes the influencing factors of corrosion and scaling tendency, so as to provide theoretical guidance and suggestions for the later optimization of coal handling water. The analysis shows that the water quality of Fugu water and hongliulin mine is weakly alkaline, and the ion content before and after pulping is relatively low, which has little impact on the corrosion. However, several key factors such as conductivity and Cl- content should be considered when studying the corrosion of the pipeline during long-term operation.
