摘　　要：在鼓泡吸收装置中分别进行了电石渣与石灰石浆液脱硫性能试验,研究了3种不同有机酸添加剂对电石渣pH缓冲能力、脱硫效率和电石渣利用率的影响.结果表明:电石渣浆液在脱硫过程中的pH缓冲能力远远低于石灰石浆液;加入添加剂延长了维持高脱硫效率的时间,在相同条件下3种添加剂的强化效果依次为:柠檬酸>己二酸>酒石酸.Carbide slag and limestone slurry flue gas desulfurization tests were conducted in a bubbling reactor to study the effects of three organic acicl additives on the pH buffer capacity, desulfurization efficiency and utilization rate of the carbide slag. Results show that the carbide slag slurry has a pH buffer capacity far lower than limestone slurry; the addition of organic acid additives prolongs the time period in which high desulfurization efficiency is maintained, and citric acid has the strongest enhancing effect among the three additives under same conditions, followed by adipic acid and tartaric acid.
