在化工生产中 ,换热设备的管壳程常集积污垢物 ,而清除污垢历来是一项费时费力、难度较大的工作。如何多快好省地清洗换热设备 ,一直是广大工程技术人员攻关的课题之一。七、八十年代 ,国内将大流量高压力射流技术应用于化工设备的清洗上 ,取得了较为明显的效果。山西焦化集团 In chemical production, the heat exchange equipment often accumulates fouling on the shell and tube of the heat exchangers, and removing dirt has always been a time-consuming and difficult task. How to clean the heat exchanger more quickly and economically has always been one of the topics that the majority of engineers and technicians tackled. In the seventies and eighties, the domestic large-flow high-pressure jet technology applied to the cleaning of chemical equipment, and achieved more obvious results. Shanxi Coking Group
