摘要:
为了解决石化企业在用管线细管道内油品的静电问题,开展了油品内电荷注入试验研究。通过理论分析,论证了可以通过有源的方式消除细管道内油品静电;采用直流高压源、 数字电荷量表、法拉第筒、示波器、试验电极、试验油品等组件了注入电流试验系统;研究了电极电压、表面积等对注入电流的影响。研究结果表明:有源静电消除应选择曲率半径大的电极,并建议进行光滑处理,避免尖端的出现;注入电流与施加电压近似成线性关系;注入电流与电极表面积近似成线性关系;试验测试到的最大注入电流为1.12 nA,根据注入电流与施加电压及电极表面积的关系,注入电流可以更大。
Abstract:
At present, the electrostatic eliminator for the oil in the pipeline used in the petrochemical enterprises is the passive and selfinduced eliminator, which is mainly used for the electrostatic elimination of oil in the pipeline with the diameter of more than 200 mm. In order to solve the electrostatic problem of oil in the thin pipeline, the experimental study on the charge injection in the oil was carried out. The feasibility of the electrostatic elimination for the oil in the thin pipeline by the active way was proved through the theoretical analysis. The experiment system of injection current was established by using the DC high voltage source, digital charge meter, Faraday cup, oscilloscope, test electrode, test oil and so on, and the influence of electrode voltage, surface area and other factors on the injection current was studied. The results showed that the active electrostatic elimination should choose the electrode with the large curvature radius, and the smooth processing should be carried out to avoid the appearance of tips. The injecting current was approximately linear to the applied voltage and the surface area of the electrode. The measured maximum injection current was 1.12 nA, and the injection current could be larger according to the relationship between the injecting current and the applied voltage, as well as the surface area of the electrode.
