沼气发电机组在使用过程中不可避免会出现一些问题，当然需要及时进行处理才行，比如说噪音问题，下面小编带您来看看相关的治理措施。

Some problems will inevitably occur during the use of biogas generator units, which of course need to be dealt with in a timely manner. For example, noise problems, the following section will show you the relevant governance measures.

(a)、进排风降噪：机房的进风通道和排风通道分别做隔音墙体，进风通道和排风通道内设置消音片。在通道内有一段距离进行缓冲，这样就能降低声源从机房内向外辐射的强度。

(a) . Air inlet and exhaust noise reduction: the air inlet channel and exhaust channel of the machine room shall be respectively provided with sound insulation walls, and the air inlet channel and exhaust channel shall be provided with sound attenuation pieces. There is a certain distance in the channel for buffering, which can reduce the intensity of sound source radiation from the machine room to the outside.

(b)、控制机械噪声：发电机房内顶部和四周墙上铺设吸声系数高的吸、隔声材料，主要用来消除室内混响，降低机房内声能密度及反射强度。为防止噪声通过大门向外辐射，设置放火隔音铁门。

(b) Control of mechanical noise: sound absorbing and insulating materials with high sound absorption coefficient are laid on the top and surrounding walls of the generator room, which are mainly used to eliminate indoor reverberation and reduce the sound energy density and reflection intensity in the machine room. In order to prevent noise from radiating outward through the gate, set fire and sound insulation iron doors.

(c)、控制排烟噪声：排烟系统在原有一级消音器的基础上安装特制二级消音器，可以保证机组排烟噪声的有效控制。排烟管长度超过10米就要加大管径，以减少发电机组排气背压。以上的处理可以改善发电机组的噪声及背压，通过降噪处理，机房内发电机组的噪声在室外可以达到用户的要求。

(c) Control of smoke exhaust noise: the smoke exhaust system is equipped with a special secondary muffler on the basis of the original primary muffler, which can ensure the effective control of smoke exhaust noise of the unit. If the length of the smoke exhaust pipe exceeds 10m, the pipe diameter shall be increased to reduce the exhaust back pressure of the generator set. The above treatment can improve the noise and back pressure of the generator set. Through noise reduction, the noise of the generator set in the machine room can meet the user's requirements outdoors.

沼气发电机组降噪工程的噪音治理措施如上，另外沼气发电机组的机房降噪要求机房内有充足的空间，如果用户不能提供充足面积的机房，降噪的效果就会大打折扣。更多相关内容就来我们网站http://www.huannengpower.com咨询吧！

The noise control measures for the noise reduction project of the biogas generator set are as above. In addition, the noise reduction of the machine room of the biogas generator set requires sufficient space in the machine room. If the user cannot provide a machine room with sufficient area, the noise reduction effect will be greatly reduced. More relevant content will come to our website http://www.huannengpower.com Consult!
