Diesel generator set is a kind of small-scale power generation equipment, which refers to power machinery that uses diesel and other fuels and diesel engines as prime movers to drive generators to generate electricity. The complete unit is generally composed of diesel engine, generator, control box, fuel tank, starter and control battery, protection device, emergency cabinet and other components. The whole can be fixed on the foundation, used for positioning, or mounted on a trailer for mobile use. So it is widely used in mines.
3. The field site
Diesel generators are non-continuous operation power generation equipment. If continuous operation exceeds 12 hours, the output power will be about 90% lower than the rated power. Although the diesel generator set has low power, it is widely used in field sites and other departments as a backup power source or temporary power source due to its small size, flexibility, light weight, and complete facilities for easy operation and maintenance.

Diesel engines are widely used due to their high thermal efficiency. Off-highway diesel engines are the mainstay of the off-highway engine market and are mainly used in agricultural machinery (such as tractors), construction machinery (such as excavators, loaders, bulldozers), material handling machinery (such as forklifts), and multi-purpose equipment (such as generator sets, pumps) )Wait. Among off-highway diesel engine emissions, NOx and PM emissions are the most serious, accounting for approximately 20% and 36% of total NOx and PM emissions, respectively.

Among the diesel components, except for 99.7% (75.7% of N2, 10% of CO2, 8% of water vapor, and 6% of O2), it is harmless to humans, and the remaining 0.3% (0.2% of NO, 0.01%) (NO2, 0.03% HC, 0.05% CO, 0.01% SO2, and less than 0.01% PM) are harmful substances, and it is the culprit for the formation of acid rain and destruction of the ozone layer. As human beings pay more and more attention to the environment, eliminating diesel exhaust pollution has become a major topic of concern. Therefore, developed countries have taken diesel engine pollution emissions as one of the important contents of environmental governance, and formulated corresponding emission control standards. These hazardous substances are controlled by the emission standards for off-highway motorized equipment.
With the rapid development of private and foreign-funded enterprises in China and the shortage of electricity and power grids in some places, factory diesel engine units are favored by customers for their durability, low consumption, cleanliness, high efficiency, and low maintenance costs. However, when the enterprise uses the diesel generator set to supply power by itself, it has brought serious noise interference to the diesel generator room. This noise pollution has caused great harm to the enterprise and its surrounding environment. In line with international standards, ISO9000 and ISOI4000 systems have clear requirements in terms of corporate environmental protection. These factors make the use of diesel generators limited. Therefore, the control of such noise pollution is imperative.
