Abstract

The invention discloses a low-noise silencer which is good in noise reduction effect. The low-noise silencer comprises a first silencing device, a second silencing device and a third silencing device. One end of the first silencing device is connected with an air inlet pipe. The other end of the first silencing device is connected with the second silencing device through a first connecting pipe. The other end of the second silencing device is connected with the third silencing device through a second connecting pipe. The other end of the third silencing device is connected with a buffering air pipe. The middle portion of the buffering air pipe is connected with an air outlet pipe. The end of the air inlet pipe is provided with a first fixing plate. Two second fixing plates are arranged between the first silencing device and the second silencing device. A third fixing plate is arranged on the third silencing device. Thread holes are formed in the first fixing plate, the second fixing plates and the third fixing plate respectively.

Description

technical field [0001] The invention relates to a noise reduction device, in particular to a low-noise muffler. Background technique [0002] The generator set is a high-intensity noise equipment, and its noise pollution is very serious. In order to reduce the noise pollution of the generator set, a muffler is generally installed in the generator set to reduce noise. The noise reduction effect of the existing muffler is not good, and the air discharge cannot meet the requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low noise muffler with good noise reduction effect. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a low-noise muffler, comprising: a first muffler, a second muffler and a third muffler, one end of the first muffler is connected to the intake pipe The other end of the first muffler is connected to the secon...
