Noise as a source of pollution, the harm is relatively large. If you want to solve the noise problem of diesel generator set, the first thing is to solve the noise caused by exhaust air, smoke, etc. You can solve the noise by installing mufflers, using sound insulation materials and so on. Next, let's take a look at the relevant content about solving the noise of diesel generator set together:
Specific Measures to Solve Noise of Diesel Generator Set
1. Noise reduction of air intake and exhaust: the air intake and exhaust passages in the engine room are sound-insulating walls respectively, and silencer plates are set in the air intake and exhaust passages. There is a distance within the channel to buffer it, which reduces the intensity of the sound source radiating from the inside to the outside of the computer room.
2. Controlling mechanical noise: Lay sound absorption and insulation materials with high sound absorption coefficient on the top and surrounding walls of the computer room, which are mainly used to eliminate indoor reverberation and reduce sound energy density and reflection intensity in the computer room. To prevent noise from radiating outwards, set fire and sound insulation iron door.
3. Controlling smoke exhaust noise: The smoke exhaust system can ensure effective control of smoke exhaust noise of the unit by installing a special secondary silencer on the basis of the original primary silencer. If the length of exhaust pipe exceeds 10m, the pipe diameter should be enlarged to reduce the exhaust back pressure of the generator unit.
Six Principles for Noise Control of Diesel Generator Room
1. All noise treatment measures affect the normal operation and maintenance of diesel generator units.
2. Diesel generator room should adopt enclosed structure, considering both sound insulation and indoor ventilation to reduce engine room reverberation.
3. Due to the restriction of high-voltage lines and transformer houses in urban planning and adjacent residential buildings, the civil dimensions of computer rooms shall not exceed 10*4*7 square meters. Therefore, the intake and exhaust pipes in engine room shall be vertical and adequate air intakes and heat dissipation requirements shall be considered.
4. Diesel generators are close to residential buildings. In addition to the original vibration isolation measures, vibration isolation measures should also be taken.
5. Considering the strong noise of the exhaust pipe of the diesel generator set, the exhaust noise of the diesel generator set should be eliminated by using the impedance compound muffler.
6. In order to ensure ventilation, the induced draft fan should be added under the intake pipe and the radiator fan should be added on the exhaust pipe wall.
