Sound insulation and noise elimination project of power generator room

The generator sets produce a great deal of radiation heat during the operation, so the cooling and ventilation of the unit is very important in the design of the engine room. Only by ensuring enough air flow in the engine room and taking away the heat from the generator in time can the normal working condition of the generator be satisfied. If there is no good cooling and ventilation, the unit will be power loss, and the unit high water temperature shutdown, thus affecting the use of the unit.

The noise of the generator set is mainly divided into three parts: smoke exhaust noise, mechanical noise and unit vibration noise. The noise reduction of the three parts is carried out for environmental noise reduction.

The generator must be in sound engineering design and construction according to the specific circumstances of the room. In order to ensure the normal work of the unit, we must pay attention to the following aspects when designing the muffler project of the generator:

1. Intake system: every diesel generator will need a lot of fresh air when working, so there is enough air intake in the engine room.

2, exhaust system: diesel generator, will produce large amounts of heat, the generator can work normally, room temperature not exceeding 50 degrees Celsius, and the optimum conditions of diesel engine, the room temperature should be below 37.8 degrees Celsius, the sucking part of heat out of the room.

3, safety system: the engine room shall not be equipped with fuel, phase box, shall not pile up flammable and explosive materials, fire equipment should be configured.

Generator insulation engineering content

In the incident wave anechoic to porous materials, can stir holes or fiber air movement, close to the surface of the air hole wall or fiber, due to the impact of the hole wall, produce viscous effect, the friction of the sound energy conversion of heat to acoustic and porous materials, so as to obtain attenuation. The engine room is used as a relatively airtight environment, and the inlet and outlet are used as damping mufflers to reduce the leakage of noise. The muffler can reach 25dB/m.

1, access to the room sound insulation: in a convenient generating unit in and out and the room staff convenient principle to set one or two door, with a metal frame, containing high quality insulation material, the thickness of 8cm to 12cm.

2 、 sound absorption wall and sound absorption ceiling

3. Sound insulation of air intake system

4, ventilation system noise insulation.

5 、 flue noise elimination system
