发电机组厂家解析柴油发电机组环保降噪如何解决 Generator manufacturers analyze how to solve the environmental protection and noise reduction of diesel generator sets

During the operation of diesel generator sets, a small amount of waste and tiny solid particles are generated, and the main hazard is noise, with a sound value of around 108 decibels, which seriously affects people's normal work and life.

In order to solve this environmental pollution, the generator set manufacturer has developed an advanced diesel generator sound insulation system that can effectively transmit noise out of the machine room.

The noise reduction and environmental protection project of the generator room must be designed and constructed according to the specific situation of the room. In order to ensure the normal operation of the unit, attention must be paid to the following aspects when designing the generator room noise reduction project:

1. Security system: Fuel tanks and phase boxes shall not be installed in the computer room, flammable and explosive materials shall not be stacked, and fire-fighting equipment shall be provided. At the same time, electrical equipment such as parallel cabinets should be isolated from the generator room to avoid affecting the working life of electrical components.

2. Air intake system: Each diesel generator set requires a large amount of fresh air during operation, so the machine room has sufficient air intake.

3. Exhaust system: When the diesel generator set is working, a large amount of heat is generated. In order to ensure the normal operation of the generator set, the ambient temperature in the machine room should not exceed 50 degrees Celsius. For diesel engine operating conditions, the ambient temperature in the machine room should be below 37.8 degrees Celsius, and a portion of the heat needs to be extracted from the machine room.

The main content of the sound insulation project for the generator room is:

1. Sound insulation of the entrance and exit passages in the computer room: One or two soundproof doors are set up based on the principle of facilitating the transfer of generator sets in and out, as well as the convenience of personnel working in the computer room. The doors are made of metal frame and are equipped with high-quality soundproof materials, with a thickness of 8cm to 12cm.

2. Sound insulation of the air intake system: Install sound-absorbing slots and soundproof walls on the air intake surface, and adopt a forced air intake method to maintain the fresh air required for the normal operation of the unit.

3. Sound insulation of exhaust system. Install sound-absorbing slots and soundproof walls on the exhaust surface, and adopt a forced exhaust method to minimize the working environment temperature of the generator.

4. Smoke duct silencing system: Install a two-stage damping silencer on the smoke duct outside the computer room to reduce engine exhaust noise while not affecting exhaust emissions.

5. Acoustic walls and ceilings are installed with suction cup sound materials in the computer room to prevent noise from spreading and rebounding from the roof, reducing the decibel level of indoor noise.
