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.

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.
