摘　　要：在实验室模拟活性焦法脱硫的富气成分,研究了反应条件对产出的焦亚硫酸钠品质和SO_(2)吸收率的影响。结果表明,反应终点的pH值是4.0,合适的反应温度是50~60℃,反应压力宜大于15.0 kPa,富气的SO_(2)体积浓度宜大于4.0%。为类似工程项目的工艺设计提供了理论参数依据。The effect of reaction conditions on the quality of sodium metabisulfite and the absorption rate of sulfur dioxide gas was studied using simulated gas in laboratory.The results show that the pH value of the reaction endpoint is 4.0,the appropriate reaction temperature is 50.0~60.0℃,the reaction pressure should be higher than 15.0 kPa,and the volume concentration of enriched sulfur dioxide gas should be higher than 4.0%.The research results provide theoretical parameters for the process design of similar engineering projects.
