In order to reduce noise pollution, the generator room should have necessary sound insulation and noise reduction measures

Noise pollution is closely related to the people. With the development of my country's economy and society, various new types of noise sources continue to emerge, and outdoor activity noise and indoor noise pollution are also increasingly frequent and diverse. The noise of the generator room cannot be ignored either. Experts point out that source prevention and control is one of the most effective ways to prevent and control noise pollution. In order to reduce the impact on the environment and people during the operation of diesel generator sets, the noise source of the exhaust gas of diesel generator sets should be dealt with first. Take noise reduction measures, and at the same time, there should be necessary sound absorption and sound insulation measures for the architectural design of the generator room.

 

       Today, the topic of #my country's revision of the law to further strengthen the prevention and control of noise pollution# has rushed to the hot search. It is understood that my country's current environmental noise pollution prevention and control law has been implemented since March 1, 1997. For more than 20 years, the situation of noise pollution prevention and control in my country has occurred. With major changes, the Law on the Prevention and Control of Environmental Noise Pollution has been unable to meet the requirements of the new situation and needs to be revised and improved urgently.

 

       Noise pollution is closely related to the people. With the development of my country's economy and society, various new types of noise sources continue to emerge, and outdoor activity noise and indoor noise pollution are also increasingly frequent and diverse. The noise of the generator room cannot be ignored either. Experts point out that source prevention and control is one of the most effective ways to prevent and control noise pollution. In order to reduce the impact on the environment and people during the operation of diesel generator sets, the noise source of the exhaust gas of diesel generator sets should be dealt with first. Take noise reduction measures, and at the same time, there should be necessary sound absorption and sound insulation measures for the architectural design of the generator room.

 

       1. When building the wall of the generator room, it is required that the ash joints are filled and full, and no holes or gaps should be left. For the painting of the inner wall, the surface should not be dense and smooth, and a certain amount of porous sound-absorbing effect should be mixed into the painting material. sexual material. For example, the sound-absorbing layer composed of cement, lime paste and wood chips. If conditions permit, the inner wall and ceiling can be decorated with sound insulation boards, and the noise reduction effect will be better. If the siding is decorated with porous materials, the perforation area should account for at least 20% to 25% of the total area. A layer of porous sound-absorbing material is filled between the wall panel and the wall, and the sound-absorbing effect is better.

 

       2. The diesel generator room and the operation room are separated by a partition wall, and an observation window with two layers of glass is excavated on the partition wall. Float glass with a thickness of 5~6mm is used for the second-layer glass, and the distance between the second-layer glass is not less than 80mm. The upper end of the glass facing the computer room should preferably be slightly inclined to the floor surface of the computer room, so that the noise reflection effect is better, and it can prevent It mists. The more sealed the glass and window frame, the window frame and the partition wall, the better the sound insulation effect. The sound insulation operation room and the machine room are separated by solid double walls. The floor of the operation room should be made about 0.8m higher than the floor of the unit. The doors between the sound insulation operation and writing rooms should be made of double-layer plywood, and the plywood should be filled with elastic porous sound insulation materials, such as broken foam plastic and glass fiber. cotton. If it is made into one door and two soundproof doors, the noise reduction effect is better. Of course, the gap between the door and the door frame, the door frame and the partition wall should be as sealed as possible, and the operating surface of the diesel engine of the unit should face the sound insulation room as much as possible. After this treatment, the noise can be reduced by about 40dB, and the noise in the operating room can be reduced. It is controlled below 75dB, thereby reducing the damage of noise and smoke to the human body and improving the working conditions of the operators in the machine room.

 

       This draft on the prevention and control of noise pollution strengthens the requirements for prevention and control at the source, improves the product noise limit system, increases the planning and control requirements for industrial noise and transportation noise, and increases environmental vibration control standards and measures to prevent and control noise pollution from the source. As a company with 15 years of experience in the production and manufacture of diesel generator sets, Tingbo Electric Power should pay more attention to the noise pollution problem when the generator set is used. In the design of the generator set and the setting of the engine room, it should be more active to find effective noise reduction measures. method, the unit is more environmentally friendly!
