Diesel engine tail gas silencer

Abstract

The invention discloses a diesel engine tail gas silencer, and relates to a tail gas silencing device. The diesel engine tail gas silencer comprises a shell, a silencing assembly, a first baffle, a second baffle, a first expansion chamber, a second expansion chamber, a third expansion chamber, a fourth expansion chamber and rock wool, wherein the shell is provided with a gas inlet and a gas outlet; the silencing assembly comprises two fixing pieces arranged in the shell, a plurality of pipelines with meshes arranged between the two fixing pieces, the first baffle arranged between the fixing piece and a first blocking piece on one side of the gas inlet, and the second baffle arranged between the fixing piece and a first blocking piece on one side of the gas outlet; the first expansion chamber is defined by the first baffle, the first blocking piece and the shell; the second expansion chamber is defined by the first baffle, the fixing piece and the shell; the third expansion chamber is defined by the fixing piece, the second baffle and the shell; the fourth expansion chamber is defined by the second baffle, the first blocking piece and the shell; and the rock wool wraps the outer side walls of the pipelines with the meshes. The diesel engine tail gas silencer has the following beneficial effects that the noise absorption area is increased so as to improve the noise absorption effect, the structure is simplified, and the tail gas noise absorption efficiency is high.

Description

technical field [0001] The invention relates to an exhaust muffler, in particular to an exhaust muffler for a diesel engine. Background technique [0002] Existing diesel generator sets generate electricity by burning diesel, and the exhaust gas for combustion needs to be discharged from the exhaust pipe. At this time, a large amount of exhaust gas is discharged from the exhaust pipe, and the exhaust noise is large, and the pollution caused by the noise affects the user's health and experience. [0003] Existing exhaust mufflers exist in the market, but the existing mufflers have poor noise absorption effect, and the mufflers are bulky, often need to take up a lot of space, resulting in low efficiency. [0004] In order to solve the above problems, a diesel engine exhaust muffler has been developed, which can absorb the exhaust noise emitted by the engine with maximum efficiency, thereby reducing the overall noise of the unit, and the exhaust muffler occupies a small space a...
