Abstract
Изобретение относитс к теплоэнергетике и может быть использовано дл снижени шума выхлопных трубопроводов агрегатов. Цель изобретени - повышение эффективности глушени шума. Устройство содержит газовод 2, выполненный в виде конической спирали с отверсти ми и заглушенным торцом 4, в котором установлена перепускна труба 5 с заглушенными торцами. Газ закручиваетс в газоводе и дросселируетс через р ды специальных отверстий в перепускную трубу, а из нее через отверсти газовода - внутрь спирали газовода, котора служит рефлектором, излучающим звук в направлении ее большего диаметра. 1 з.п. 4 ил.The invention relates to a power system and can be used to reduce the noise of exhaust piping units. The purpose of the invention is to increase the efficiency of jamming noise. The device comprises a gas duct 2, made in the form of a conical helix with openings and a plugged end 4, in which an overflow pipe 5 is installed with the ends closed. The gas twists in the gas duct and is throttled through rows of special holes in the bypass pipe, and from there through the gas duct holes into the inside of the gas duct spiral, which serves as a reflector, radiating sound in the direction of its larger diameter. 1 hp 4 il.
