摘　　要：为实现高效近零排放的目标和更好的社会效益,某电厂对其脱硫系统进行提效改造,采用海水脱硫方案后,系统总效率可以达到98%。本文分析了该电厂脱硫改造方案的特点和实现方式,介绍了海水脱硫的原理和工艺组成,并分别分析了脱硫后的固体、液体和气体污染物对周边环境的影响。其目的是在实现提效的同时提供了一种燃煤电站脱硫改造的高效近零排放方案,以供海滨电厂脱硫改造参考。In order to achieve the goal of high efficient near-zero emissions and better social benefits, a power plant improved the efficiency of its desulfurization system. After the seawater desulfurization scheme is adopted, the total system efficiency can reach 98%. This paper analyzes the characteristics and implementation of the desulfurization retrofit scheme of the power plant, introduces the principle and process composition of seawater desulfurization, and separately analyzes the impact of solid, liquid and gas pollutants on the surrounding environment after desulfurization. The purpose is to provide an efficient near-zero emission solution for desulfurization transformation of coal-fired power plants while achieving efficiency improvement, for reference of desulfurization transformation of seaside power plants.
