摘要
石油化工等工艺装置的工艺样品中,含有大小和数量不等的颗粒物,目前在线分析系统样品预处理中使用的常规过滤器极易被堵塞,导致在线分析中断。因此设计了一款既能有效过滤样品中的颗粒物,又能确保在线分析系统长周期稳定、可靠运行的颗粒物自清洗过滤系统。从设计、验证、应用几个方面,详细阐述了该颗粒物自清洗过滤系统。
The process sample from petrochemical and other process units contain particulate matters with different sizes and quantities and the conventional filter used for their pretreatment is easily blocked which may suspend the online analysis.For this season,a self-cleaning filtration system was designed which can effectively filter the particles in the sample and ensure the long-term stable and reliable operation of the on-line analysis system.From the aspects of design,verification and application,this self-cleaning filtration system was described.
