Abstract

The invention discloses a silencer for a diesel generating set. The silencer comprises a shell. A gas inlet and a gas outlet are formed in the shell, and the shell is provided with an interlayer. A cooling water channel is arranged in the interlayer, and a sound absorption material is arranged on the inner wall of the shell. A first barrel is arranged in the shell, and a first cavity is formed between the first barrel and the shell. A second barrel is arranged in the first barrel, and a second cavity is formed between the second barrel and the first barrel. A third barrel is arranged in the second barrel, and a third cavity is formed between the third barrel and the second barrel. The third barrel is connected with the gas inlet, and a plurality of holes are evenly distributed in the barrel wall of each of the first barrel, the second barrel and the third barrel. The first barrel, the second barrel and the third barrel are arranged, so that the gas flow divergence ratio of gas is increased, and then the sound deadening capacity is improved; and the sound absorption material is used in cooperation, and therefore the low-frequency noise, intermediate-frequency noise and high-frequency noise of engine exhaust gas can be lowered.

Description

technical field [0001] The invention relates to a muffler, in particular to a muffler for a diesel generator set. Background technique [0002] Diesel generator set is a kind of power equipment that uses diesel engine as the prime mover and drives synchronous generator to generate electricity. It is widely used in fixed or mobile power generation equipment such as national important infrastructure, military bases, post and telecommunications, financial securities, medical and health care, etc. Among them, when ensuring the power supply of important departments or densely populated areas, the requirements for noise control are very high. At present, the noise reduction effect of the mufflers used in diesel generator sets is not ideal, and the noise pollution is relatively serious. Therefore, it needs to be solved urgently. Moreover, the mufflers of existing diesel generator sets have poor heat dissipation and are prone to damage, which greatly shortens the service life. Inc...
