摘要/Abstract

摘要： 采用超声电化学强化浮选技术对山西古交屯兰细粒煤进行了脱硫试验。以氢氧化钙为电解质、无水乙醇为助剂，考察了无水乙醇用量、强化处理时间、电解电流、超声功率对脱硫率的影响，并与电化学强化浮选和超声强化浮选的脱硫效果进行了比较。结果表明，在乙醇用量为30 mL、强化处理时间为20 min、电解电流为1.5 A、超声功率为250 W条件下，超声电化学强化浮选的脱硫率和精煤产率分别可达75.42%和72.15%，效果优于其它两种方法。

Abstract: The technology of flotation enhanced by sonoelectrochemical process was used in the desulfuration test on Shanxi Gujiaotun fine coal. With calcium hydroxide as the electrolyte and ethanol as the additive, the effect of ethanol dosage, treatment time, electrolytic current and ultrasonic power on desulfuration rate was investigated. The desulfuration results were compared with those of electrochemically enhanced flotation and ultrasonically enhanced flotation. The results show that, at an ethanol dosage of 30 mL, treatment time of 20 min, electrolytic current of 1.5 A and ultrasonic power of 250 W, this process can achieve a desulfuration rate and clean coal yield of 75.42% and 72.15% respectively , better than those by other two methods.
