摘要
采用高压管道粉尘在线检测装置对天然气站场内多管旋风分离器和过滤分离器进出口管道内颗粒物浓度和粒径分布进行测定,得到多管旋风分离器和过滤分离器的实际分离性能。现场测试结果与常压常温下过滤分离设备的性能测定结果对比表明:多管旋风分离器现场的分离效率与实验室测试结果相一致,常压常温工况下的性能测定数据可以作为评价高压实际工况运行的指标。过滤分离器现场测试结果与常压常温下测试结果存在差别,主要原因在于滤芯现场使用过程中,滤芯纤维失效会导致较大颗粒穿透,使过滤分离器效率下降。
The concentration and size distribution of dust particles at the inlet and outlet of multi-cyclone separators and fil- ters in two domestic natural gas stations are measured by the particle online measuring devices for high pressure gas, and the separation performances of in-site cyclones and filters are evaluated. These field test results are compared with the laboratory test results under atmospheric temperature and pressure. The field test results of multi-cyclone separators are in agreement with the laboratory test results, and so the data measured under atmospheric temperature and pressure can be used as the in- dicator for evaluating separation performance of multi-cyclone under high pressure condition. However, the field test results of filters show some differences from the laboratory test results. The overall efficiency of filters decreases with the operation period because some large particles can penetrate the filter candle.
