Изобретение относитс  к очистке трубопроводов от различного рода загр знений .The invention relates to the cleaning of pipelines from various kinds of contaminants.

Известен способ очистки внутренней поверхности трубопроводов, заключающийс  в прокачке через внутреннюю полость трубопровода рабочей жидкости с сообщением последней вращательного движени  1 3A known method of cleaning the internal surface of pipelines, which consists in pumping working fluid through the internal cavity of the pipeline with the message of the last rotational movement 1 3

Недостатком данного способа  вл етс  низка  эффективность очистки.The disadvantage of this method is low cleaning efficiency.

Цель изобретени  - повышение эффективности очистки.The purpose of the invention is to increase the cleaning efficiency.

Цель достигаетс  тем, что согласно способу очистки внутренней поверхности трубопроводов, заключающемус  в прокачке через внутреннюю полость трубопровода рабочей жидкости с сообщением последней вращательного движени , в центральную часть потока рабочей жидкости подают газ. Газ можно подавать импульсно.The goal is achieved in that according to the method of cleaning the internal surface of pipelines, which involves pumping working fluid through the internal cavity of the pipeline with the last rotational movement, gas is fed into the central part of the working fluid flow. Gas can be pulsed.

Способ осуществл етс , следующим образом.The method is carried out as follows.

Очищаемый трубопровод подстыковывают к устройству завихрени , выполненному в виде улитки с тангенциальным подводом рабочей жидкости и осевом газа.The pipeline to be cleaned is docked to a vortex device made in the form of a cochlea with a tangential supply of working fluid and axial gas.

Рабочую жидкость нагнетают через тангенциальный ввод.The working fluid is injected through the tangential injection.

После прохождени  улитки устройства завихрени  в центральную часть закрученного потока рабочей жидкости посредством патрубка подают газ. По дача гааа производитс  двум  потоками, один из которых посто нный, второй импульсный , причем давление газа импульсного потока выше давлени  посто нного .After the snail device passes the vortex device, gas is supplied to the central part of the swirling flow of the working fluid. The supply of gas is produced by two streams, one of which is constant, the second is pulsed, and the pressure of the pulsed gas is higher than the pressure of the constant.

Таким образом, снижаетс  расход рабочей жидкости путем создани  в очищаемом трубопроводе кольцевой - пристеночной формы течени , при которой газ  вл етс  наполнителем и увеличиваетс  давление и скорость жидкости в пристеночной области, что повышает эффективность очистки. Кроме этого, nor средствам импульсной подачи газа про исходит ускорение пристеночного сло  жидкости и вызываетс  волнообразное изменение толщины пограничного сло  жидкости, что в совокупности приводит к возрастанию кас ательных напр жений трени  на очищаемой поверх-, ности и повышению эффективности очистки.Thus, the flow rate of the working fluid is reduced by creating an annular — near-wall form of flow in the pipeline being cleaned, at which the gas is a filler and the pressure and velocity of the liquid in the near-wall area increase, which increases the cleaning efficiency. In addition, nor by means of a pulsed gas supply, the surface layer of the fluid accelerates and causes a wave-like change in the thickness of the boundary layer of the fluid, which together leads to an increase in tangential friction stresses on the surface being cleaned and an increase in the cleaning efficiency.
