본 발명은 발전기용 소음기에 대한 것으로서, 더욱 상세하게는 비상용 발전기로부터 배출되는 배기가스의 유해성분을 침전시켜 배출시킬 수 있는 발전기용 소음기에 대한 것이다.The present invention relates to a muffler for a generator, and more particularly, to a muffler for a generator capable of precipitating and discharging harmful components of exhaust gas discharged from an emergency generator.

비상용 발전기는 상용 전원의 공급 중단시에 대체 전력으로 공급하는 비상 전원으로서, 디젤 연료를 에너지원으로 사용하는 디젤발전기가 주로 사용된다.Emergency generators are emergency power sources that are supplied as alternative power when commercial power supply is interrupted. Diesel generators that use diesel fuel as an energy source are mainly used.

이때 연료를 연소시킨 후 배기가스가 배출될 때 발생되는 소음을 감소시키기 위하여 발전기에는 소음기가 장착된다.The generator is equipped with a silencer to reduce the noise generated when the exhaust gas is discharged after the fuel is combusted.

공개특허 제2002-0040119호(공개일자 2002년 05월 30일)Published Japanese Patent Application No. 2002-0040119 (published on May 30, 2002) 등록실용신안 제20-0468563호(등록일자 2013년 08월 14일)Registration Practical Utility Model No. 20-0468563 (Registration date August 14, 2013)

발전기에서 배출되는 배기가스에는 질소산화물이나 황산 등 매연물질이 포함되어 있다. 따라서 이들 배기가스가 그대로 배출되면 환경오염을 일으킨다. 종래의 소음기는 배기가스로부터 발생되는 소음은 저감시킬 수 있더라도 배기가스에 포함된 환경오염을 일으키는 매연물질은 제거하지 못한다는 문제점이 있었다.The exhaust gas discharged from the generator contains soot such as nitrogen oxide or sulfuric acid. Therefore, when these exhaust gases are discharged as they are, environmental pollution occurs. The conventional silencer has a problem in that the noise generated from the exhaust gas can be reduced but the soot material causing environmental pollution contained in the exhaust gas can not be removed.

본 발명은 상기의 문제점을 해결하기 위한 것이다. 본 발명은 발전기로부터 배출되는 배기가스의 매연물질을 저감시키는 한편 소음을 감소시킬 수 있는 발전기용 소음기를 제공하는 것을 목적으로 한다.The present invention is intended to solve the above problems. An object of the present invention is to provide a silencer for a generator capable of reducing the amount of soot in the exhaust gas discharged from a generator and reducing noise.

본 발명에 따른 발전기용 소음기는 흡음케이스와, 스크류와, 탱크 및 분사수단을 포함한다. 상기 흡음케이스는 배기가스가 유입되는 유입구와, 상기 배기가스가 유출되는 유출구가 형성되며, 상기 배기가스의 소음을 흡수하기 위한 흡음벽을 구비한다. 상기 스크류는 상기 배기가스를 상기 흡음벽으로 분산시키기 위하여 상기 배기가스의 흐름방향으로 상기 흡음케이스의 내부에 장착된다. 상기 분사수단은 상기 탱크에 수용된 물을 상기 배기가스에 분사시킬 수 있도록 상기 흡음벽에 장착된 분사노즐과, 상기 탱크의 물을 분사노즐로 공급하기 위한 펌프와, 상기 펌프에서 상기 분사노즐로 연결된 분사관을 구비한다.The silencer for a generator according to the present invention includes a sound-absorbing case, a screw, a tank, and an injection means. The sound absorbing case is provided with an inlet through which exhaust gas flows and an outlet through which the exhaust gas flows, and a sound absorbing wall for absorbing noise of the exhaust gas. The screw is mounted inside the sound-absorbing case in the flow direction of the exhaust gas to disperse the exhaust gas into the sound-absorbing wall. The injection means includes an injection nozzle mounted on the sound-absorbing wall so as to inject water contained in the tank into the exhaust gas, a pump for supplying water of the tank to the injection nozzle, and a pump connected to the injection nozzle And has a spray tube.

또한, 상기의 발전기용 소음기에 있어서, 상기 흡음케이스 분사된 물이 상기 탱크로 배수되도록 상기 탱크 상부에 위치하며, 상기 탱크로 배수될 수 있는 배출구가 형성된 것이 바람직하다.In the silencer for a generator, it is preferable that an exhaust port, which is located in the upper portion of the tank and can be drained to the tank, is formed such that water sprayed from the sound-absorbing case is discharged to the tank.

또한, 상기의 발전기용 소음기에 있어서, 상기 흡음벽은 다공성 알루미늄 흡음재인 것이 바람직하다.In the muffler for generator, it is preferable that the sound-absorbing wall is a porous aluminum sound-absorbing material.

또한, 상기의 발전기용 소음기에 있어서, 상기 탱크는 상기 물을 배출시키기 위한 드레인밸브가 형성된 것이 바람직하다.In the muffler for a generator, it is preferable that the tank has a drain valve for discharging the water.

본 발명에 의하면 흡음케이스로 배출되는 배기가스에 분사수단을 이용하여 물을 분사시킴으로써 배기가스의 포함된 매연물질을 침전시킬 수 있다. 따라서 소음기로 배출되는 배기가스에서 유해성분을 저감시킬 수 있다.According to the present invention, it is possible to deposit soot containing the exhaust gas by injecting water into the exhaust gas discharged to the sound-absorbing case using the injection means. Therefore, harmful components can be reduced in the exhaust gas discharged to the silencer.

도 2는 도 1의 측면도이다.1 is a cross-sectional view of an embodiment of a silencer for a generator according to the present invention,

도 1 및 도 2를 참조하여 본 발명에 따른 발전기용 소음기의 일 실시예를 설명한다. 1 and 2, an embodiment of a silencer for a generator according to the present invention will be described.

디젤 엔진 발전기의 경우 배기가스에는 질소산화물이나 황산 등 매연 물질이 포함되어 있다. 따라서 발전기에서 배출되는 배기가스의 소음을 저감시킬 뿐만 아니라 배기가스에 함유된 매연물질도 감소시킬 필요가 있다.In the case of a diesel engine generator, the exhaust gas contains nitrogen oxide or sulfur dioxide. Therefore, it is necessary not only to reduce the noise of the exhaust gas emitted from the generator but also to reduce the soot contained in the exhaust gas.

본 실시예의 소음기는 발전기에서 배출되는 배기가스로 인한 소음을 감소시킬 뿐만 아니라 매연물질을 저감시키는 역할을 한다. 이를 위하여 본 발명에 따른 발전기용 소음기는 흡음케이스(10)와, 스크류(20)와, 탱크(25) 및 분사수단(30)을 포함한다. The silencer of the present embodiment not only reduces the noise due to the exhaust gas discharged from the generator but also serves to reduce the soot material. To this end, the silencer for a generator according to the present invention includes a sound-absorbing case 10, a screw 20, a tank 25, and a spraying means 30.

흡음케이스(10)는 배기가스가 유입되는 유입구(11) 및 배기가스가 유출되는 유출구(13)가 형성된다. 그리고 흡음케이스(10)는 배기가스가 통과할 때 배기가스의 소음을 흡수하기 위한 흡음벽(15)을 구비한다. 흡음벽(15)은 분사수단(30)에서 분사되는 물에 손상되지 않도록 다공성 알루미늄 흡음재로 형성되는 것이 바람직하다. 그리고 흡음벽(15)에는 분사수단(30)에서 분사된 물이 탱크(25)로 배출되기 위한 배출구(17)가 형성되어 있는 것이 바람직하다. 이를 위해서 흡음케이스(10)는 탱크(25)의 상부에 위치하며, 배출구(17)는 탱크(25)로 물이 배출될 수 있도록 형성된다.The sound absorbing case 10 is formed with an inlet 11 through which exhaust gas flows and an outlet 13 through which exhaust gas flows. And the sound-absorbing case 10 has a sound-absorbing wall 15 for absorbing the noise of the exhaust gas when the exhaust gas passes through it. The sound-absorbing wall 15 is preferably formed of a porous aluminum sound-absorbing material so as not to be damaged by the water sprayed from the spraying means 30. [ In addition, the sound-absorbing wall 15 is preferably provided with a discharge port 17 through which the water sprayed from the spraying means 30 is discharged to the tank 25. For this purpose, the sound-absorbing case 10 is located at the upper part of the tank 25, and the discharge port 17 is formed so that water can be discharged to the tank 25.

스크류(20)는 배기가스를 흡음벽(15)으로 분산시키기 위해서 배기가스가 흘러가는 방향으로 흡음케이스(10)의 내부에 장착된다. 즉 스크류(20)는 흡음케이스(10)의 유입구(11)에서 유출구(13) 방향으로 배기가스가 흘러가는 방향에 위치한다. 배기가스가 유입구(11)로 유입되면 스크류(20)에 의하여 흡음벽(15)으로 분산된다.The screw 20 is mounted inside the sound-absorbing case 10 in the direction in which the exhaust gas flows in order to disperse the exhaust gas into the sound-absorbing wall 15. That is, the screw 20 is located in a direction in which the exhaust gas flows from the inlet 11 of the sound-absorbing case 10 toward the outlet 13. When the exhaust gas flows into the inlet 11, it is dispersed by the screw 20 into the sound-absorbing wall 15.

탱크(25)는 흡음케이스(10) 내부에 분사시킬 물을 수용하며, 수용된 물을 배출시키기 위한 드레인밸브(26)가 형성되어 있다. 탱크(25)에 수용된 물에는 요소수가 포함되어 디젤 엔진에서 배출되는 매연을 감소시켜 준다.The tank 25 accommodates the water to be sprayed inside the sound-absorbing case 10, and a drain valve 26 for discharging the water contained therein is formed. The water contained in the tank 25 contains urea water to reduce the amount of soot discharged from the diesel engine.

분사수단(30)은 탱크(25)에 수용된 물을 배기가스에 분사시키는 역할을 한다. 이를 위하여 분사수단(30)은 분사노즐(31)과, 펌프(33) 및 분사관(35)을 구비한다. 분사노즐(31)은 흡음벽(15)에 복수 개 장착된다. 펌프(33)는 탱크(25) 내부의 물을 분사노즐(31)이 분사할 수 있도록 분사노즐(31)에 공급하는 역할을 하며, 분사관(35)은 펌프(25)에서 공급되는 물이 분사노즐(31)에 도달할 수 있도록 펌프(25)와 분사노즐(31)에 연결된다.The injecting means 30 serves to inject the water contained in the tank 25 into the exhaust gas. To this end, the injection means 30 is provided with a spray nozzle 31, a pump 33 and a spray pipe 35. A plurality of injection nozzles (31) are mounted on the sound-absorbing wall (15). The pump 33 serves to supply the water inside the tank 25 to the injection nozzle 31 so that the injection nozzle 31 can inject the water. Is connected to the pump (25) and the injection nozzle (31) so as to reach the injection nozzle (31).

본 실시예의 경우 흡음케이스(10)의 유입구(11)로 배기가스가 유입되면 배기가스는 스크류(20)와 충돌하여 흡음벽(15)으로 분산된다. 흡음벽(15)에서는 소음을 저감시키는 한편 흡음벽(15)에 설치된 분사노즐(31)에서 요소수를 함유한 물이 분사되어 배기가스에 포함된 매연성분을 흡수한다. 매연성분을 흡수한 물은 흡음케이스의 배출구(17)를 통하여 다시 탱크(25)로 회수된다. 따라서 배기가스가 흡음케이스(10)에서 배출될 때에는 매연이 감소되어 나간다.In this embodiment, when the exhaust gas flows into the inlet 11 of the sound-absorbing case 10, the exhaust gas collides with the screw 20 and is dispersed in the sound-absorbing wall 15. In the sound-absorbing wall 15, noise is reduced while water containing urea water is injected from the injection nozzle 31 provided in the sound-absorbing wall 15 to absorb the soot component contained in the exhaust gas. The water absorbing the soot component is returned to the tank 25 through the outlet 17 of the sound absorbing case. Therefore, when the exhaust gas is discharged from the sound-absorbing case 10, the soot is reduced.
