PNEUMOGEAR AND THE METHOD USED FOR THE PIPELINES CLEANING Russian patent published in 2007 - IPC B08B5/02 F28G3/16 

FIELD: chemical industry; oil-producing industry; other industries; methods and devices for the pipelines cleaning.

SUBSTANCE: the invention is pertaining to the pipeline transportation may be used at cleaning of the interior surfaces of the pipelines from the organic and inorganic settlings, including as well as for cleaning from impurities of the of the technological pipelines, sewer pipes, the shower systems and other interior surfaces of the different engineering structures made out of the metallic and non-metallic materials. The pneumogear is introduced in the pipeline, feed in it the compressed gas under pressure of 40-600 atm., which is passing through the groove in the piston from the inlet chamber into the accumulating chamber, and cyclically at the piston motion the compressed air enters in the pressure dropping holes executed in the body and disposed at the angle of 30-89° concerning the longitudinal axis, of the body towards the inlet chamber. The number of the air discharges from the accumulating chamber makes from 0.2 up to 12 discharges per a second, that ensures the effective cleaning of the pipeline by the pneumopulses at the pneumogear movement in it and increases efficiency of the pneumogear cleaning operation.

EFFECT: the invention ensures the effective cleaning of the pipelines and the increase efficiency of the pneumogear cleaning operation.
