More Information
Summary:The present invention comprises: an inner tube (20) with a plurality of through-holes (23) on the outer circumferential surface; an outer tube (30) coupled to the outer side of the inner tube concentrically; and a sound absorber (40) formed in a capsule structure to be stacked in multiple layers between the inner tube (20) and the outer tube (30). Therefore, the maintainability and durability of the whole silencer can be increased by the configuration of a waste gas silencer for a ship composed of the inner tube, the capsule type sound absorber, and the outer tube.
