Description

Technical Field

[0001] This invention relates to the field of diesel generator set technology, and more particularly to an aftertreatment system for diesel generator sets. Background Technology

[0002] Diesel generator sets, as an important backup power source, are widely used in many fields such as industrial production, commercial sites, and residential communities, playing a crucial role in ensuring power supply. However, the exhaust emissions and noise pollution generated during their operation have many negative impacts on the environment and human health.

[0003] With increasing environmental awareness and increasingly stringent environmental regulations, controlling exhaust emissions from diesel generator sets has become a crucial issue that urgently needs to be addressed. Traditional diesel generator sets have many shortcomings in exhaust treatment, often lacking a complete after-treatment system or using outdated and inefficient technologies. This results in large quantities of harmful pollutants such as nitrogen oxides (NOx) and particulate matter (PM) being emitted into the atmosphere. These pollutants not only cause environmental pollution problems such as acid rain and smog, but also pose serious risks to the human respiratory and cardiovascular systems.

[0004] Meanwhile, the noise generated by diesel generator sets during operation cannot be ignored. High-decibel noise not only disturbs the normal life, work, and study of nearby residents, but may also damage the hearing of operators. Long-term exposure to noise can even lead to a series of health problems. Therefore, reducing noise pollution from diesel generator sets and improving their quiet operation is an inevitable requirement for the industry's development.

[0005] Against this backdrop, developing a highly efficient, reliable, and fully functional after-treatment system for diesel generator sets is of paramount importance. This system needs to effectively treat exhaust emissions, reduce pollutant levels to meet stringent environmental standards, and its structural design should facilitate maintenance and operation, ensuring long-term stable operation to meet the comprehensive demands of modern society for environmentally friendly, efficient, and low-noise diesel generator sets.

[0024] 5. The aftertreatment assembly is located in the exhaust chamber, and the heat generated during the exhaust gas treatment process can be discharged in a timely manner with the air flow in the exhaust chamber. This layout is conducive to the rapid dissipation of heat, avoids heat accumulation in the system, reduces the risk of component damage due to overheating, and ensures the stable operation of the aftertreatment system and the entire diesel generator set.
