摘要

为研究化学品船洗舱效果的影响因素，选择棕榈油作为典型的非挥发性化学品货物，以不锈钢内衬舱壁的化学品船为研究对象，自建物理实验系统并开发了数值仿真模型。通过对结果进行分析获得了棕榈油洗舱效果定量评价模型。实验中发现，洗舱初期的效果主要受到水射流的影响，中后期主要是由于洗舱水的溶解作用。结果表明：影响洗舱效果的主要因素是喷嘴出口的长度和直径、清洗持续时间、洗舱水的温度和动压。研究结果对相关研究具有理论参考价值，对化学品船洗舱作业的实践具有一定的指导意义。

Abstract

In order to study the factors affecting on the washing effect of chemical tankers, palm oil was selected as a typical non-volatile chemical cargo, stainless steel lined bulkhead chemical tanker was taken as a research object, while a physical experiment system was built and developed a reliable numerical simulation model was developed. The quantitative evaluation model of palm oil tank washing effect was obtained by analyzing the results.During the experiment, it was found that the water jet was mainly influencing factor in the initial stage, and the dissolution of tank washing water in the middle and later stage was the mainly influencing factor. The research results show that, the main factors affecting the tank washing effect are the length and diameter of the nozzle outlet, washing time, temperature of the tank washing water and dynamic pressure. This work has theoretical reference value for related research and good guidance significance for the practice of chemical tanker washing.
