Abstract

The invention discloses a cleaning and oil flushing device and method for a unit lubricating oil system pipeline, which are used for performing cleaning and oil flushing on the pipeline, which is arranged on site, of a unit separately and out of the unit. Namely, the unit pipeline and the device form a loop by using a metal hose, and large-flow circulating flushing is performed by using chemical cleaning agent, water and flushing oil, so that cleaning and purification requirements on the inside of the unit pipeline are met, and the problems of the traditional cleaning process of the existing petrochemical unit lubricating oil system that the cleaning process is complex, the cleaning cycle is long, the cleaning is not thorough, the unit is contaminated, safety loopholes exist and the like are solved. According to the invention, the same device is adopted to finish performing the cleaning and oil flushing of the pipeline, which is arranged on site, of the large unit separately and out of the unit, the cleaning cycle is short, the cleaning and purification are thorough, the construction is pollution free, the practicability is high, and the device and the method are especially applicable to moving construction.

Description

(1) Technical field: [0001] The invention relates to the lubricating oil system technology of a large-scale petrochemical unit, in particular to a device and method for cleaning and oil flushing of the lubricating oil system pipeline of the unit. (two) background technology: [0002] The large unit is the core equipment in the petrochemical plant, and its normal operation is an important guarantee for the normal operation of the petrochemical plant. The lubricating oil pipeline system of the petrochemical unit is one of the most important components of these components. It mainly provides lubricating oil for each bearing part of the unit and power oil for adjusting the security system. Therefore, the cleaning and purification of the internal environment of the system is very important to the safe and stable operation of the unit. [0003] During the construction of the lubricating oil system of the petrochemical unit, the lubricating oil pipeline needs to be piped on site. ...
