A small amount of tail gas is discharged during the use of the diesel generator. If the tail gas is directly discharged, it will cause certain pollution to the surrounding area. According to environmental protection requirements, and in order to further improve the quality of the surrounding area where the diesel generator set is used, because the pollutants in the tail gas of the diesel generator include nitrogen oxides, carbon monoxide, particulates, sulfides, etc. Therefore, the tail gas of diesel generator set must be treated.

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 vortex plate water washing spray method and the vortex 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 layers of vortex plates in the tower, it can increase the gas-liquid contact area and contact time, making the exhaust gas and water fully contact inside the tower and on the plate surface. The carbon black, a pollutant in the tail gas, is fully adsorbed by the water during Contact process with the spray water to 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.
