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
