도 1 및 도 2를 참조하여 본 발명에 따른 발전기용 소음기의 일 실시예를 설명한다. 1 and 2 will be described an embodiment of a generator silencer according to the present invention.
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 diesel engine generators, the exhaust gas contains soot substances such as nitrogen oxides and sulfuric acid. Therefore, it is necessary to reduce the noise of the exhaust gas emitted from the generator as well as to reduce the soot material 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 muffler of this embodiment not only reduces the noise caused by the exhaust gas emitted from the generator, but also serves to reduce the soot material. To this end, the generator silencer according to the present invention includes a sound absorbing case 10, a screw 20, a tank 25, and an injection 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 the exhaust gas flows and an outlet 13 through which the exhaust gas flows out. The sound absorbing case 10 includes a sound absorbing wall 15 for absorbing noise of the exhaust gas when the exhaust gas passes. The sound absorbing wall 15 is preferably formed of a porous aluminum sound absorbing material so as not to damage the water sprayed from the spraying means 30. In addition, the sound absorbing wall 15 is preferably provided with a discharge port 17 for discharging the water injected from the injection means 30 to the tank 25. To this end, the sound absorbing case 10 is positioned above the tank 25, and the outlet 17 is formed to discharge water into 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 to the sound absorbing wall 15. That is, the screw 20 is located in the 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, the exhaust gas is dispersed into the sound absorbing wall 15 by the screw 20.
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 water to be sprayed into the sound absorbing case 10 and has a drain valve 26 for discharging the received water. The water contained in the tank 25 includes urea water to reduce the smoke emitted 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 injection means 30 serves to inject the water contained in the tank 25 to the exhaust gas. To this end, the injection means 30 includes an injection nozzle 31, a pump 33, and an injection pipe 35. A plurality of injection nozzles 31 are mounted on the sound absorbing wall 15. The pump 33 serves to supply the injection nozzle 31 so that the injection nozzle 31 can inject the water in the tank 25, and the injection pipe 35 has the water supplied from the pump 25 It is connected to the pump 25 and the injection nozzle 31 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 the present 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, 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. Water absorbing the soot component is recovered 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, soot is reduced.
