How to Solve Environmental Noise Reduction for Diesel Generators

Generator Manufacturer Explosions: How to Solve Environmental Noise Reduction for Diesel Generators?

During operation, diesel generator sets produce a small amount of exhaust emissions and solid particles, with the primary hazard being noise. Noise levels can reach around 108 decibels, severely disrupting normal work and life.

To address this environmental issue, Runlan Power Equipment Co., Ltd. has designed and developed an advanced diesel generator sound insulation system that effectively contains noise within the generator room.

The acoustic and environmental treatment for a generator room must be designed and constructed based on the specific conditions of the site. To ensure the generator set operates properly, the following aspects must be considered during the design of the noise reduction project:

1. Safety System: The generator room must not store fuel or fuel tanks, and flammable or explosive materials should not be piled up. Firefighting equipment must be installed. Additionally, electrical equipment such as parallel cabinets should be isolated from the generator room to prevent affecting the lifespan of electrical components.

2. Air Intake System: Each diesel generator set requires a large amount of fresh air during operation, so the generator room must have sufficient air intake.

3. Exhaust System: Diesel generator sets generate significant heat during operation. To ensure proper functioning, the ambient temperature in the generator room should not exceed 50°C. For optimal diesel engine performance, the ambient temperature should be kept below 37.8°C, which necessitates exhausting a portion of the heat from the room.

Key Elements of Generator Room Soundproofing:

1. Soundproofing for Access Points: One or two soundproof doors should be installed for easy movement of generator sets and personnel. These doors should have a metal frame lined with high-quality soundproofing material, with a recommended thickness of 8cm to 12cm.

2. Soundproofing for the Air Intake System: Install sound-absorbing ducts and soundproof walls on the intake side, using forced air intake to maintain the fresh air required for normal generator operation.

3. Soundproofing for the Exhaust System: Install sound-absorbing ducts and soundproof walls on the exhaust side, using forced exhaust to minimize the operating temperature of the generator environment.

4. Exhaust Pipe Silencing System: Install a two-stage damping silencer on the exhaust pipe outside the generator room to reduce engine exhaust noise without hindering emissions.

5. Sound-Absorbing Walls and Ceiling: Install sound-absorbing materials on the walls and ceiling of the generator room to prevent noise from escaping through the roof and to reduce reverberation, thereby lowering the overall noise level inside the room.
