How does the low noise cabinet reduce noise?

Noise has a great impact on people's health, while Diesel Generator sets are accompanied by noise and noise, which is very healthy, and a low-noise box can reduce the noise to the user. influences. How does the low noise cabinet reduce noise? What is the internal structure of it?
1. The sound-absorbing material adopts fireproof, high-temperature resistant, sound-absorbing type, wave environmentally friendly sponge and 0.8mm galvanized iron plate. The perforated plate covers the box sponge, which makes noise diffusion, absorption, shock absorption and sound insulation reduce noise.
2. The air inlet system is designed on the top of the mute box of the Generator Set. It is made of galvanized iron plate for anti-turbidity and waterproofing. It is equipped with a baffle silencer system and 2 sets of 25000m3 explosion-proof fans per hour to force the wind to make the Generator work. The air is replenished in time,
3, exhaust air cooling system, dirty waste hot air in time to ensure that the temperature inside the chassis and the working temperature of the generator will not rise, to achieve the purpose of improving power generation efficiency, reducing fuel consumption and extending the service life of the generator.
4. Install KD-KZD series bag type and medium efficiency air filter in front of the air inlet box to make the air entering the chassis fresh. It can filter out 90% of the dust in the air and remove the water. Harmful gas, keeping the indoor air clean and hygienic, and prolonging the service life of the air filter on the unit.
5. Inlet and exhaust air system, in order to prevent noise from transmitting, a silencer is installed in the intake and exhaust passages and the heat dissipation passage, and a secondary sound reduction is added to the exhaust gas exhaust pipe, and the muffler achieves the purpose of outdoor noise reduction, and the noise is achieved through treatment. National standard.
6. Independent control room, for the operator to work in the noise environment for a long time, damage to the hearing and vision, provide a good working environment for the operator, use the isolation operation type without noise, install 1.0 air conditioner, data storage . Better improve the applicability of the operator.
7. The air inlet and outlet will automatically shut down the system. If there is methane content in the chassis, the smoke is higher than the standard, and the fire occurs inside the box, the smoke and air alarm system will automatically shut off the air intake and exhaust system to cut off the air intake generator box. In the case of no oxygen, the generator set cannot be operated, and the safety of the generator set is better protected.
