摘要:: 将高压管道颗粒物检测装置应用于天然气输气站场,监测不同工况下管道内颗粒物的浓度水平,评价多管旋风分离器的性能。研究发现:日常工况下输气管道内颗粒物浓度一般低于0.1 mg/m³,清管过程中浓度明显增加,清管器到达时颗粒物浓度达到峰值,约60 mg/m³,并在清管结束后的一段时间内保持较高浓度,根据颗粒物浓度的变化规律将清管过程分为4个阶段。通过分析多管旋风分离器进口和出口的颗粒物浓度和粒径分布,得到多管旋风分离器对5 μm及以上颗粒的分离效率大于80%,可有效除去10 μm以上的颗粒,多管旋风分离器在清管过程中起到保护下游管道安全运行的关键作用。

Abstract:: Online particulate matter detector is used in natural gas transmission stations to monitor particulate matter concentration in high pressure gas pipeline under different operational conditions, and to evaluate the performance of multitube cyclone separator. Results show that particulate matter concentrations are mostly below 0.1 mg/m³ under routine conditions, and may increase dramatically during pigging operations. Particulate matter concentration reaches a peak value of about 60 mg/m³ when the pig arrives, and then remains at a high level for a period of time after pigging. Generally, the pigging process can be divided into four stages in accordance with changes in particulate matter concentrations. By analyzing concentrations and particular size distribution at inlet and outlet of the multi-tube cyclone separator, its efficiency is determined to be 80% and above for the particles with diameter larger than 5 μm, and it can effectively remove the particulate matters with size above 10 μm. In summary, the separator plays an important role in protecting the downstream pipelines during pigging operations.
