柴油發(fā)電機(jī)在使用過程中有少量尾氣排出，此尾氣若直接排放對(duì)周圍會(huì)產(chǎn)生一定污染，根據(jù)環(huán)保要求，也為了進(jìn)一步提高使用柴油發(fā)電機(jī)組周邊的品質(zhì)，因?yàn)椴裼桶l(fā)電機(jī)尾氣中的污染物有：氮氧化物、一氧化碳、顆粒物、硫化物等。所以一定要對(duì)柴油發(fā)電機(jī)組的尾氣進(jìn)行處理。

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.

常規(guī)做法是引進(jìn)旋流板水洗噴淋法，引進(jìn)旋流板式噴淋塔，氣體在塔內(nèi)由下向上高速運(yùn)動(dòng)，與自上向下噴出的洗滌液相接觸，由于塔內(nèi)設(shè)置了多層旋流板，它能增加氣液接觸面積和接觸時(shí)間，使尾氣與水在塔內(nèi)和板面上充分接觸。尾氣中的污染物質(zhì)碳黑在與噴淋水接觸過程中，被水充分吸附，得以凈化；尾氣中NOx、SO2等氣態(tài)污染物通過在噴淋水中加入一定比例的NaOH使噴淋水呈堿性，在噴淋過程中，水與尾氣接觸時(shí)，發(fā)生化學(xué)反應(yīng)，使NOx、SO2等氣態(tài)污染物得到中和達(dá)到良好的處理效果。在整個(gè)尾氣凈化過程中設(shè)備無需清洗，所用的噴淋水可循環(huán)使用，可實(shí)現(xiàn)自動(dòng)控制，使用簡便。

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.
