Air exhaust duct muffler used for ship

Abstract

The invention discloses an air exhaust duct muffler used for a ship. The air exhaust duct muffler comprises a barrel body (4), the two ends of the barrel body (4) are provided with an air inlet end plate (3) and an air outlet end plate (7) respectively, the air inlet end plate (3) and the air outlet end plate (7) are provided with an air inlet pipe (2) and an air outlet pipe (8) respectively, an air inlet flange (1) is communicated with the barrel body (4) through the air inlet pipe (2), an air outlet flange (9) is communicated with the barrel body (4) through the air outlet pipe (8), the inside of the barrel body (4) is provided with a hush pipe (5) and a separating plate (6), the separating plate (6) separates the air inlet end of the barrel body (4) from the air outlet end of the barrel body (4) to form two cavities, the hush pipe (5) penetrates through the separating plate (6) and communicates the two cavities, and the circumferential wall of the hush pipe (5) is evenly provided with a plurality of circular holes. According to the spark extinguishing muffler, noise caused when tail gas of a diesel engine is exhausted can be effectively lowered.

Description

technical field [0001] The invention relates to a marine exhaust pipe muffler. Background technique [0002] Diesel sets are the core power for ships to sail, and they are also the core source of power supply for ships. However, diesel sets generate quite high noise during operation, and the noise in the exhaust emission process occupies a considerable part, which brings pollution to the environment and seriously The working and living environment of the crew is deteriorating. How to reduce the noise of the diesel unit during operation is an important aspect of improving the working and living environment. Contents of the invention [0003] In order to solve the above problems, the present invention provides a marine exhaust pipe muffler, which can effectively reduce the noise of diesel engine exhaust during exhaust. [0004] The present invention adopts the following technical solutions: a marine exhaust pipe muffler, which includes a cylinder body, an air inlet flange, ...
