The present invention relates to a noise reducing device for a vessel, which includes: an inflow pipe into which exhaust gas is introduced; a body reducing a noise of the exhaust gas introduced through the inflow pipe; a discharge pipe discharging the exhaust gas which has gone through the body; a first sound absorption member stored inside the body; a second sound absorption member stored outside the first sound absorption member; and a water tank installed on the floor of the body to supply water to the first and second absorption members. Therefore, the present invention is capable of removing harmful gas from exhaust gas, through water absorbed by an absorption member, reducing air pollution or environmental pollution by discharging the exhaust gas, excluding the harmful gas, keeping a neighboring device or component at a low temperature by keeping the body at a low temperature through the water, smoothly discharging exhaust gas of a vessel which becomes larger or is environmentally regulated about exhaust gas, as well as removing harmful gas from the exhaust gas, meeting requirements for environmental regulation in accordance with the manufacture of the vessel, and reducing noises caused by the discharge of the exhaust gas from an engine room.

    선박용 소음저감장치에 관한 것으로, 배기가스가 유입되는 유입관, 상기 유입관을 통해 유입된 배기가스의 소음을 저감시키는 본체 및 상기 본체를 통과한 배기가스가 배출되는 배출관이 구비된 선박용 소음저감장치로서, 상기 본체의 내부에 수용되는 제1 흡음부재; 상기 제1 흡음부재의 외측에 수용되는 제2 흡음부재; 상기 제1 흡음부재 및 제2 흡음부재에 물이 공급되도록 상기 본체의 저면에 설치되는 물 탱크를 마련하여 흡음부재에 흡수된 물에 의해 배기가스에 포함된 유해가스를 제거할 수 있고, 유해가스가 제거된 배기가스를 배출시킴으로써 환경오염 또는 대기오염을 줄일 수 있으며, 물에 의해 본체가 저온으로 유지함으로써 주변의 장치 또는 부품을 저온으로 유지시킬 수 있고, 배기가스에 대한 환경 규제 또는 대형화 되는 선박의 배기가스를 원활하게 배출시킬 수 있음은 물론 배기가스에 포함된 유해가스를 제거할 수 있으며, 선박의 제조에 따른 환경규제 요건을 충족시킬 수 있고, 엔진룸 등에서 발생된 배기가스의 배출에 따른 소음을 줄일 수 있다는 효과가 얻어진다.
