Изобретение относитс  к технике очистки внутренней поверхности труб от отложений и может быть использовано при очистке труб в химической, нефт ной и теплоэнергетической промышленност х , а также водопроводной и канализационной сет х.The invention relates to a technique for cleaning the internal surface of pipes from sediments and can be used for cleaning pipes in the chemical, oil and heat power industries, as well as water supply and sewage networks.

Известен способ очистки внутренней поверхности труб путем воздействи  на ее стенки импульсами давлени  воспламен емого взрывчатого вещества l.A known method of cleaning the inner surface of pipes by acting on its walls with pulses of pressure of a flammable explosive l.

Недостатком известного способа  вл етс  постепенное снижение ударного импульса при распространении взрывной волны вдоль стенок трубы от одного из ее концов, где размещено твердое взрывчатое вещество.The disadvantage of this method is the gradual decrease of the shock pulse during the propagation of the blast wave along the pipe walls from one of its ends, where a solid explosive is placed.

.Целью изобретени   вл етс  интенсификаци  процесса очистки.The purpose of the invention is to intensify the cleaning process.

Указанна  цель достигаетс  тем, что согласно способу очистки внутренней поверхности труб путем воздействи  на стенки очищаемой трубыThis goal is achieved in that according to the method of cleaning the inner surface of pipes by acting on the walls of the pipe being cleaned

импульсами давлени  воспламен емого взрывчатого вещества, очищаемую трубу заполн ют взрывчатым веществом, а в качестве последнего используют смесь детонирующих газов.pulses of pressure of a flammable explosive; the pipe to be cleaned is filled with an explosive; and the mixture of detonating gases is used as the last.

В результате известного эффекта ускоренного самопроизвольного перехода в длинных шероховатых трубах медленного горени  в дetoнaцию импульс давлени  возникает вскоре As a result of the known effect of an accelerated spontaneous transition in long, rough, slow-burning pipes to detonation, a pressure pulse arises soon

10 после воспламенени  и при этом, распростран  сь с посто нной скоростью и давлением вдоль очищаемой трубы на сколь угодно длинном пути, не ослабевает с рассто нием, так как 10 after ignition and at the same time, propagating with constant velocity and pressure along the pipe being cleaned for an arbitrarily long path, does not weaken with distance, since

15 по мере продвижени  ударной волны в процессе горени  посто нно вовлекаютс  все новые порции смеси детонирующих газов.15, as the shock wave advances in the process of burning, all new portions of the mixture of detonating gases are constantly involved.

Кроме того, существенным фактором, In addition, a significant factor

Источники информации, прин тые во внимание при экспертизе 1 Авторское свидетельство СССР №709200, кл. В 08 В , 1972.20 intensifying the process of cleaning the inner surface of pipes, is the formation of an additional retopion wave inside the pipe at the site of the onset of detonation, which sharply increases the pressure in the pulse. The pressure in the pipe can be controlled by changing the composition of detonating gases, as well as placing pressure on the diaphragm gate pressure pulse as a result of which a five to sixfold increase in pressure can be achieved. The proposed method also allows spontaneous increase in pressure pulses from the protrusions behind (the contamination and thereby more actively affecting the most polluted areas. Using the proposed method allows to simplify the cleaning technology of pipes, does not require complicated devices for its implementation, in addition, intensify the process of cleaning pipes without limiting their length. Formulation of the internal surface of pipes by applying pressure pulses of flammable explosive to the walls of a pipe, characterized in that, for the purpose of intensification. filled with explosives, and, as the latter, using a mixture of detonating gases.
