| titleOfInvention | The discarded innoxious cleaning process of crude oil pipeline |
| abstract | The invention discloses a kind of innoxious cleaning processes of discarded crude oil pipeline, it is slowly moved in pipeline using the pigging train being made of four groups of pipe cleaners and the scavenger specially fluid column formed between four groups of pipe cleaners, compressed nitrogen air column and clean water fluid column, the residue for being adhered to inner wall of the pipe adequately impregnate and thoroughly cleaning.The present invention clears up discarded crude oil pipeline using the method for physical chemistry combined cleaning, it can remotely monitor, the travel speed of intelligence adjusting pipe cleaner, it is accurate to determine pipe cleaning liquid inside to the dissolution time of residue, it ensure that the cleaning effect of pipeline, residue and cleaning waste liquid in pipeline are not landed collection respectively, are realized and are prevented to pollute from source.Fastness residue in the certifiable discarded crude oil pipeline of scavenger specially efficiently, quickly, thoroughly dissolves, and cooperation clean water cleaning reaches in pipe without wax, without greasy dirt, without dirt after clearing up discarded pipe, the effect of metal true qualities can be presented. |
