DEVICE FOR MECHANOCHEMICAL CLEANING OF PIPELINE INNER SPACE Russian patent published in 2016 - IPC B08B9/00 F28G9/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to transportation and storage of oil products, in particular, to cleaning of inner cavities of main oil pipelines and oil product pipelines from deposits and residues of transported product prior to changing type of transported product. Device of mechanochemical cleaning of pipeline inner space comprises a section for mechanochemical cleaning, a section for storing deposit solvent and a storage section. Section for mechanochemical cleaning includes drive, lining and cleaning discs, located behind control unit, unit for transmitting location and disc rotation drive, mechanochemical activation chamber formed by alternating drive, lining, cleaning discs and rotating discs with spring-loaded polymer wear-resistant brush, and comprising a pressure line for deposit solvent, provided with injection nozzles, drainage chamber for mechanochemical activation and a heating coil for deposit solvent. Behind mechanochemical activation chamber there are, located in housing, high-pressure pump, connected with pressure line of solvent and solvent intake line, leading to feed line of high-pressure pump, and a sludge pump connected with sludge pressure line and intake line of dissolved deposits. Deposit solvent storage section includes a tank with clean solvent, equipped with flexible intake line of clean solvent, connected to feed line of high-pressure pump.

EFFECT: invention provides high degree of cleaning pipeline inner surface of pipeline from sediments and residues of transported product.
