蒸汽动力舰船机舱环境中的 DTBP 实测研究

摘要

利用 Tenax‐TA 吸附管对某蒸汽动力舰船海上航行工况和码头停泊停机工况下的机舱环境空气进行富集采样，并通过气相色谱‐质谱联用仪分析 DTBP 含量。研究表明：该舰船航行期间蒸汽动力系统存在高浓度 DTBP 散发，机舱环境中 DTBP 质量浓度（0．036 mg／m3）是停泊停机状态的近10倍（0．004 mg／m3）。因此，建议在开展蒸汽动力舰船舱室空气污染治理时，应完善相关标准，改善涡轮机油品质，加强涡轮机油的 DTBP释放控制。%This paper investigates the DTBP in steam power ship engine room environment during voyage by using Tenax‐TA adsorption tube and gas chromatography‐mass spectrometry (GC/MS ) . The study indicates that high concentration of DTBP volatilized by lubricating oil exists in the ship cabin .In order to control the steam power ship cabin air pollution ,the related standards ,lubricating oil quality and emission control should be improved .
