摘要
在烧结法生产氧化铝的流程中,管道结垢十分普遍,水力清管技术(PIG技术)是一种先进的机械式清洗除垢技术。本文介绍了水力清管技术(PIG技术)的技术要点、清理设备、清理方案的编制,并介绍了烧结法生产氧化铝流程中硅渣输送管道采用PIG技术维护管道的经济效果。与原人工敲击清垢法相比,年节约清理费用17多万元。
During the flow of manufacture alumina by sinter,it is popular that there are some furring in the pipe,the PIG technical is the advanced machined type technical to get off the furring.This article describes the technical point,cleaning equipment and the cleaning project of PIG technical,and introduces the economical affect that adapts the PIG technical to remain pipes during the manufacture process of alumina by sinter.It saves the cleaning charge more than 170000 RMB/a compared with the metal strike to get off the furring.
