柴油发电机在使用过程中有少量尾气排出，此尾气若直接排放对周围会产生一定污染，根据环保要求，也为了进一步提高使用柴油发电机组周边的品质，因为柴油发电机尾气中的污染物有：氮氧化物、一氧化碳、颗粒物、硫化物等。所以一定要对柴油发电机组的尾气进行处理。

During the use of diesel generators, a small amount of exhaust gas is discharged. If this exhaust gas is directly discharged, it will cause certain pollution to the surrounding area. According to environmental protection requirements, it is also necessary to further improve the quality of the surrounding area when using diesel generators, because the pollutants in the exhaust gas of diesel generators include nitrogen oxides, carbon monoxide, particulate matter, sulfides, etc. So it is necessary to treat the exhaust gas of the diesel generator set.

常规做法是引进旋流板水洗喷淋法，引进旋流板式喷淋塔，气体在塔内由下向上高速运动，与自上向下喷出的洗涤液相接触，由于塔内设置了多层旋流板，它能增加气液接触面积和接触时间，使尾气与水在塔内和板面上充分接触。尾气中的污染物质碳黑在与喷淋水接触过程中，被水充分吸附，得以净化；尾气中NOx、SO2等气态污染物通过在喷淋水中加入一定比例的NaOH使喷淋水呈碱性，在喷淋过程中，水与尾气接触时，发生化学反应，使NOx、SO2等气态污染物得到中和达到良好的处理效果。在整个尾气净化过程中设备无需清洗，所用的喷淋水可循环使用，可实现自动控制，使用简便。

The conventional approach is to introduce the swirling plate water washing spray method and the swirling plate spray tower. The gas moves at high speed from bottom to top inside the tower and comes into contact with the washing liquid sprayed from top to bottom. Due to the installation of multiple swirling plates in the tower, it can increase the gas-liquid contact area and contact time, allowing the exhaust gas and water to fully contact inside the tower and on the plate surface. The pollutant carbon black in exhaust gas is fully adsorbed by water during contact with spray water, and can be purified; Gaseous pollutants such as NOx and SO2 in the exhaust gas are treated by adding a certain proportion of NaOH to the spray water to make it alkaline. During the spray process, chemical reactions occur when the water comes into contact with the exhaust gas, resulting in the neutralization of gaseous pollutants such as NOx and SO2 and achieving good treatment results. During the entire exhaust gas purification process, the equipment does not need to be cleaned, and the spray water used can be recycled and automatically controlled, making it easy to use.

柴油发电机尾气处理工程的设计建设，除应遵守本技术规范外，还应满足国家现行的相关强制性规范的。

The design and construction of diesel generator exhaust gas treatment engineering should not only comply with this technical specification, but also meet the relevant mandatory national regulations currently in effect.

应根据企业柴油发电机尾气中气体污染类、浓度及处理要求等条件确定柴油发电机尾气处理工程的处理规模和处理工艺，做到、经济合理、技术可靠。

The treatment scale and process of diesel generator exhaust gas treatment engineering should be determined based on conditions such as gas pollution types, concentrations, and treatment requirements in enterprise diesel generator exhaust gas, in order to achieve economic rationality and technical reliability.

处理工程技术方案的选择应满足影响评价报告书批复文件的要求，柴油发电机尾气处理后应稳定达到有关国家和地方排放规范的。

The selection of engineering and technical solutions for treatment should meet the requirements of the impact assessment report approval document, and the tail gas treatment of diesel generators should stably meet the relevant national and local emission standards.
