Abstract

Pipeline leakage accidents of dielectric liquid often occurs in chemical industry, while the investigations on flow electrification of leakage pipe are few. In this study, experiments were conducted to measure and analyze the streaming current inside the pipe and the leakage current of the pipe wall in both intact and leak pipes. Two kinds of diesel oil, namely the light heavy diesel oil and heavy diesel oil, were selected as the flowing media. Furthermore, an empirical expression of the space charge density and the streaming current based on the modified velocity equation was proposed. The space charge density distribution obtained from the experimental streaming current was compared with the theoretical values. The results show that the space charge density obtained from experiments by the proposed expression is in good agreement with the theoretical value.

完整和泄漏管道中的流动电气化实验研究
化工行业经常发生电介质液体的管道泄漏事故,而对泄漏管道的流动电化研究却很少。本研究通过实验测量和分析了完好管道和泄漏管道的管内流动电流和管壁泄漏电流。实验选择了轻质重柴油和重质柴油两种柴油作为流动介质。此外,还提出了基于修正速度方程的空间电荷密度和流动电流的经验表达式。实验中获得的空间电荷密度分布与理论值进行了比较。结果表明,根据所提出的表达式从实验中得到的空间电荷密度与理论值十分吻合。
