柴油发电机噪声治理，发电机房降噪处理措施 Diesel generator noise control, noise reduction measures for generator room

目前，社会对环保的要求越来越高，怎样有效控制噪声污染是一项艰巨的任务。由于大多数民用发电机都位于人口密集的居民区的地下室，这些地区的环境要求很高，而柴油发电机组的噪音经常成为周围环境的主要噪音源，为了能够有效的对柴油发电机组进行噪声治理，我们先来了解分析柴油发电机的噪声源有哪些？

1、 机械噪音

柴油机在运作的过程中，各部件会因为运转时受到气体的压力以及惯性力的变化等，会引起震动。各个部件都在发出噪音，使整个机器的噪音很大需要进行噪音治理。如：传动齿轮噪音、配气机构的噪音等等。

2、 燃烧噪音

燃烧噪音指的是柴油发电机组在运作时，柴油燃烧会产生结构上的振动及噪音。

3、 排气噪音

柴油发电机噪音中最大的就是排气噪音，它是一种高速、高温的气流噪音。产生排气噪音的原因是噪音声波在排气管道中受到空气等因素与排气系统相互作用施压，最终形成了较大的噪音。

4、 进风口噪音

柴油发电机在运作的过程中，必须保证供应足够的风源。这样做既可以保证发电机能正常工作，另外也是考虑到柴油发电机的散热器问题。柴油发电机的进风系统在运作时不可避免的就会产生较大的噪音问题。

At present, society has increasingly high requirements for environmental protection, and effectively controlling noise pollution is a daunting task. Due to the fact that most civilian generators are located in the basements of densely populated residential areas with high environmental requirements, the noise from diesel generators often becomes the main source of noise in the surrounding environment. In order to effectively control the noise from diesel generators, let's first understand and analyze the sources of noise from diesel generators?

1. Mechanical noise

During the operation of a diesel engine, various components may experience vibrations due to changes in gas pressure and inertial forces during operation. Each component is making noise, which makes the entire machine very noisy and requires noise control. For example, noise from transmission gears, noise from valve mechanisms, and so on.

2. Combustion noise

Combustion noise refers to the structural vibrations and noise generated by diesel combustion during the operation of a diesel generator set.

3. Exhaust noise

The biggest noise in diesel generators is exhaust noise, which is a high-speed, high-temperature airflow noise. The reason for the generation of exhaust noise is that the sound waves in the exhaust pipe are subjected to the interaction and pressure of air and other factors with the exhaust system, ultimately forming a large amount of noise.

4. Inlet noise

During the operation of diesel generators, sufficient air supply must be ensured. This approach not only ensures the normal operation of the generator, but also takes into account the radiator issue of the diesel generator. The intake system of diesel generators inevitably generates significant noise during operation.
