Problems solved by technology
In order to reduce noise, the exhaust system adopts a conventional muffler. The vertically installed baffle inside the muffler blocks the propagation of sound waves while allowing airflow to pass through. Although it has a certain noise reduction effect, the noise is still relatively large, especially in recent years. As the speed increases and the power increases, the requirements for the muffler are getting higher and higher.
Moreover, the existing mufflers are not only complicated in structure, but also have high production costs, are heavy and difficult to disassemble and repair, and have a short service life, which greatly wastes resources

Embodiment
[0010] Example: see figure 1 , a generator muffler, comprising an intake pipe 1, a muffler pipe and an exhaust pipe 3. The muffler pipe includes a primary muffler section 21, a secondary muffler section 22 and a final muffler section 23, and the primary muffler section 21, the secondary muffler section 22 and the final muffler section 23 are connected by The flanges 4 are connected sequentially; in the specific construction process, an O-ring is provided between the two connected flanges 4 . The intake pipe 1 is connected to the end of the primary muffler section 21 , and the exhaust pipe 3 is connected to the end of the final muffler section 23 .
[0011] The primary noise-absorbing section 21 is provided with several sound-absorbing partitions I5, and the sound-absorbing partition I5 separates the primary noise-absorbing section 21. A number of ventilation holes are opened on the sound-absorbing partition I5, and two adjacent sound-absorbing partitions I5 Dislocation distr...

The invention discloses an electricity generator silencing device. The electricity generator silencing device comprises an air inlet pipe, a silencing pipe and an air exhaust pipe, wherein the silencing pipe comprises a primary silencing section, a secondary silencing section, and a final silencing section, the air inlet pipe is connected to the end of the primary silencing section, and the air exhaust pipe is connected to the end of the final silencing section; multiple first sound absorption clapboards are arranged in the primary silencing section, a sound absorption cavity is arranged in the secondary silencing section, the end, near the primary silencing section, of the sound absorption cavity is provided with an air inlet hole, the end, near the final silencing section, of the sound absorption cavity is provided with an air outlet hole, and multiple second absorption clapboards are arranged in the final silencing section. According to the electricity generator damping silencing device, noises generated in the working process of an electricity generator can be effectively lowered; meanwhile, the electricity generator damping silencing device is simple in structure, convenient to overhaul, and longer in service life.
Description
technical field [0001] The invention relates to the technical field of generator noise reduction, in particular to a generator noise reduction device. Background technique [0002] With the development of society, generators have been widely used in various fields, and their power components are mainly gasoline engines and diesel engines, so they will generate relatively large noise during operation. In order to reduce noise, the exhaust system adopts a conventional muffler. The vertically installed baffle inside the muffler blocks the propagation of sound waves while allowing airflow to pass through. Although it has a certain noise reduction effect, the noise is still relatively large, especially in recent years. As the speed increases and the power increases, the requirements for the muffler are getting higher and higher. Moreover, the existing muffler not only has a complicated structure, but also has high production costs, is heavy and difficult to disassemble and repai...
