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(guò)程中,被水充分吸附,得以?xún)艋晃矚庵蠳Ox、SO2等氣態(tài)污染物通過(guò)在噴淋水中加入一定比例的NaOH使噴淋水呈堿性,在噴淋過(guò)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(guò)程中設(shè)備無(wú)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(jiǎn)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.
