본 고안은 개스터어빈 엔진의 배기소음을 줄이기 위한 소음감소기로서, 특히 개스터어빈 엔진의 배기구로 부터 나오는 고속, 고압 및 고온의 개스에 견디면서 개스배출시 발생하는 소음을 줄여주는 소음감소기에 관한 것이다.The present invention relates to a noise reducer for reducing exhaust noise of a gas turbine engine, and more particularly, to a noise reducer which reduces noise generated when exhausting gas while enduring high speed, high pressure, and high temperature gas emitted from an exhaust port of a gas turbine engine. .
통상의 차량엔진에 부착되는 기존의 차량소음기는 고온고압의 배기개스를 배출하는 개스터어빈 차량엔진의 배기개스에는 적합하지 않아 일반적으로 개스터어빈 엔진의 경우 통상 소음기를 부착하지 않고 운용하였었다.Existing vehicle silencers that are attached to conventional vehicle engines are not suitable for the exhaust gas of gas turbine engines that discharge high-temperature, high-pressure exhaust gas. In general, gas turbine engines were operated without a silencer.
따라서, 개스터어빈의 배기시 발생되는 소음에 의해 현장의 작업환경을 악화시킬 뿐아니라 환경오염문제가 점차 사회문제화되면서 소음에 대해서도 환경규제가 날로 강화되어 여러 가지 규제를 받게 되는 문제점이 있었다.Therefore, as the noise generated during exhaust of the gas turbine is not only worsening the work environment of the site, but also environmental pollution problem is gradually becoming a social problem, there was a problem that the environmental regulation is also strengthened day by day to receive various regulations.
이에 본 고안은 상기한 바와 같은 제문제점을 해소시키기 위한 것으로 개스터어빈 엔진의 배기구로 부터 나오는 고속, 고압 및 고온의 개스에 견디면서 개스배출시 발생하는 배기소음을 흡수하는 소음감소기를 제공하는 데 그 목적이 있다.In order to solve the problems described above, the present invention provides a noise reducer that absorbs exhaust noise generated when gas is discharged while enduring high speed, high pressure, and high temperature gas from the exhaust port of a gas turbine engine. There is a purpose.
이러한 목적을 달성하기 위한 본 고안의 소음감소기는, 소음흡수용 구멍이 다수 형성된 얇은 금속판재로 공기의 흐름을 받지 않도록 유선형의 형상으로 형성된 다수의 안내날개와, 상기 안내날개의 내부에 채워져 배기가스의 소음을 흡수할 수 있는 흡음재 및, 상기 안내날개를 종횡으로 배열하여 개스터어빈의 배기구에 고정시키도록 된 몸체로 구성된 것이다.Noise reduction device of the present invention for achieving this purpose, a plurality of guide blades formed in a streamlined shape so as not to receive the flow of air to a thin metal plate formed with a number of holes for noise absorption, filled in the guide blades exhaust gas Sound absorbing material capable of absorbing the noise of the, and the guide wings are arranged in a vertical and horizontal arrangement to be fixed to the exhaust port of the gas turbine.
이렇게 구성된 본 고안은 개스터어빈 엔진의 배기구로 부터 발생되는 개스가 소음감소기를 통과하는 안내날개에 내장된 흡음재에 배기소음이 일부 흡수되어 소음이 감소되는 효과가 있다.The present invention is configured so that the gas generated from the exhaust port of the gas turbine engine is partially absorbed by the sound absorbing material built into the guide vane passing through the noise reducer to reduce the noise.
이하, 첨부한 예시도면을 참조하여 본 고안을 자세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 다른 1 실시예를 도시한 것으로, 몸체(1)의 내붕 안내 날개(2)가 종횡으로 배열되어 고정된 것으로, 상기 몸체(1)의 전면에 형성된 플랜지(3)는 배기개스 배출구에 고정되도록 보울트 구멍이 다수 형성되고, 몸체(1)의 내부면에는 내부 흡음판(4)이 부착되어 있고, 이 몸체(1) 전체 형상은 실시예에 4각형 형상으로 도시되어 있으나 배출구의 형상에 따라 원형, 다각형 내지는 기타의 형상으로 될 수도 있 .1 is a view showing another embodiment of the present invention, in which the inner roof guide vanes 2 of the body 1 are vertically arranged and fixed, and the flange 3 formed on the front surface of the body 1 is exhausted. A plurality of bolt holes are formed to be fixed to the gas outlet, and an inner sound absorbing plate 4 is attached to the inner surface of the body 1, and the entire shape of the body 1 is illustrated in the embodiment as a quadrangular shape, but Depending on the shape, it may be circular, polygonal or other shape.
또한, 안내날개(2)는 제3도에 도시된 바와 같이 소음흡수구멍(5)이 다수개 형성된 얇은 금속판을 전면부에 얇은 칼날부(6)가 형성되고, 몸체는 가늘게 직선형으로 형성되어 공기의 흐름을 방해하지 않도록 유선형으로 형성되어 있을 뿐아니라 이 안내날개(2)의 몸체(1) 내 배치도 종횡으로 배치되어 배압(backup presure)현상 등 배기개스의 흐름을 방해하지 않도록 하여 개스터어빈 엔진의 출력에 영향을 주지 않게 되는 것이다.In addition, as shown in FIG. 3, the guide blade 2 has a thin metal plate on which a plurality of noise absorbing holes 5 are formed, and a thin blade portion 6 is formed on the front surface thereof. Not only is it streamlined so as not to disturb the flow of air, and the arrangement in the body 1 of the guide wing 2 is also arranged horizontally and horizontally so as not to obstruct the flow of the exhaust gas such as a backup presure phenomenon. It does not affect the output.
여기서 안내날개(2)의 배열은 엔진의 배기개스 흐름을 최대한 방해되지 않도록 배열되어지되, 수직 수평 또는 경사지게 하든 다양하게 변형시킬 수 있는 것이다.Here, the arrangement of the guide vanes 2 is arranged so as not to obstruct the exhaust gas flow of the engine as much as possible, and can be variously modified, whether vertically horizontal or inclined.
상기 안내날개(2) 및 내부흡음판(4)의 표면에는 다수의 소음흡수용 구멍(5)의 형성되어 있을 뿐아니라 그 내부에는 안내날개 및 내부흡음판의 가공전에 흡음재가 내장되어져 있어, 개스터어빈 엔진의 배기구로 부터 배출되는 배기가스가 소음감소기의 몸체(1) 내부로 유입되어 안내날개(2) 및 내부 흡음판(4)의 좌우로 유통되면서 내장된 흡음재에 소음이 흡음되게 된 것이다.On the surfaces of the guide vane 2 and the inner sound absorbing plate 4, not only a plurality of sound absorbing holes 5 are formed therein, but also a sound absorbing material is built into the inner surface of the guide wing and the inner sound absorbing plate. Exhaust gas discharged from the exhaust port of the inflow into the body (1) of the noise reducer is distributed to the left and right of the guide vane (2) and the inner sound absorbing plate (4) is the sound is absorbed in the built-in sound absorbing material.
이때 상기 흡음재는 특별히 한정되지 않고 고온상태에소 내구성을 유지할수 있는 것이면 되고, 특히 높은 rpm으로 회전하는 엔진의 고주파소음이 심각하므로 흡음재 선정시에도 고주파소음에 대한 흡음특성이 좋은 것이 바람직하다.In this case, the sound absorbing material is not particularly limited, and may be capable of maintaining durability at a high temperature. Particularly, since high frequency noise of an engine rotating at a high rpm is serious, it is preferable that the sound absorbing properties for high frequency noise are good even when selecting the sound absorbing material.
이렇게 구성된 본 고안은 개스터어빈 엔진의 배출덕트측의 플랜지와 몸체(1)의 선단부를 밀착시켜 플랜지와 몸체(1)의 선단부를 나사로 관통하여 나합시키므로써 엔진으로 부터 배출되는 고속, 고압 및 고온의 배기가스에 견디면서 개스배출시 발생하는 배기소음을 통과시키는 동안 안내날개(2) 및 내부흡음판(4)에 내장된 흡음재에 일부의 소음이 흡수되어 소음이 감소되게 하는 효과가 있다.The present invention configured as described above has a high speed, high pressure and high temperature discharged from the engine by tightly screwing the flange and the front end of the body 1 together with the flange of the exhaust duct side of the gas turbine engine. While passing the exhaust noise generated when the gas is discharged while enduring the exhaust gas, some noise is absorbed by the sound absorbing material built into the guide vane 2 and the inner sound absorbing plate 4, thereby reducing the noise.
