石灰石-石膏湿法烟气脱硫技术

我国的大气环境污染是典型的煤烟型污染,由燃煤排放的SO2所造成的酸雨已危及24个省、市、自治区。治理大气污染的根本途径之一是采取有效的脱硫措施,减少点、面排放源的SO2排放量。针对我国的具体情况,开发切实可行的脱硫技术,卓有成效地控制燃煤烟气中排放的SO2量。近年来,国际国内研制、开发了多种脱硫技术,在此就石灰石-石膏湿法烟气脱硫技术作一些简单探讨。

Desulphurization Technology of Flue Gas by Wet Limestone - Gypsum

The atmospheric environment belongs to a typical coal-burning pollution in China, and acid rain caused by SO2 emissions from coal-fired has been threatening 24 provinces, municipalities and autonomous regions.One of the fundamental ways to control air pollution is to take effective desulfurization measures to reduce the point and surface sources of SO2 emissions.In view of the specific situation, the practical desulfurization technology is developed to achieve the effective control of SO2 emissions from coal-fired smoke volume.Desulphurization technology of glue gas by wet limestone-gypsum was discussed based on all kinds of desulfurization technologies in international and domestic in recent years.
