Abstract
The utility model discloses a noise reduction device for operation of a low-power diesel power generating set, which comprises the following components: a sound insulation outer cover (2), an air inlet noise-eliminating door (1), an impedance compound silencer (3) and a sound insulation exhaust air channel (4). The air inlet noise-eliminating door (1) is a door plate with a certain thickness. The inner part of the door plate is composed of a labyrinth type air inlet duct. The sound insulation outer cover (2) has a sound barrier structure with a non-metal noise reduction interlayer. One end of the impedance compound silencer (3) is in threaded connection with an air outlet of the diesel engine, and the other end is connected with the sound insulation exhaust air channel (4). The other end of the sound insulation exhaust air channel (4) is communicated with outside through an exhaust shutter. In operation, the air enters the diesel engine through the air inlet noise-eliminating door (1) for being combusted. The generated exhaust is discharged into the sound insulation exhaust air channel (4) through the impedance compound silencer (3) for being exhausted out. The noise which is generated in operation of the low-power diesel power generating set is reduced through the sound insulation outer cover (2). The noise reduction device can ensure stable operation of the low-power diesel power generating set and simultaneously reduces operation noise.
