A kind of marine muffler

Abstract

The invention discloses a marine muffler which comprises a casing, an air inlet pipe and an air outlet pipe, wherein the inside of the casing is divided into a first chamber, a second chamber, a third chamber and a fourth chamber by separation boards; the air inlet pipe is communicated with the first chamber; the air outlet pipe is communicated with the fourth chamber; a first inner pipe, a second inner pipe and a third inner pipe are arranged in the casing; the first inner pipe penetrates through the third chamber and is used for communicating the first chamber with the second chamber; the second chamber is communicated with the third chamber by the second inner pipe; the third chamber is communicated with the fourth chamber by the third inner pipe; a water inlet pipe communicated with the fourth chamber is also arranged on the casing. According to the marine muffler disclosed by the invention, the emission of harmful gases can be reduced, and the muffler can be cooled.

Description

technical field [0001] The invention relates to a marine exhaust system component, in particular to a marine muffler. Background technique [0002] Most of the existing mufflers are to directly discharge the engine exhaust gas into the ambient atmosphere after the noise reduction treatment, but cannot effectively remove harmful gases such as HC, CO, NOx and the like. In addition, due to the high temperature of the engine exhaust gas, the muffler works at high temperature for a long time, causing thermal corrosion to the muffler and affecting the service life of the muffler, and the high-temperature exhaust gas will generate a huge air flow when passing through the exhaust port, resulting in huge exhaust noise. Contents of the invention [0003] The purpose of the present invention is to provide a marine muffler to reduce the discharge of harmful gas and to cool down the muffler. [0004] The marine muffler of the present invention includes a shell and air inlet and outlet...
