摘　　要：以鄂尔多斯东辰公司唐公塔矿井原煤为实验研究对象,在碱性电解质条件下,利用无隔膜型电解槽,探索电解条件对全硫脱除率的影响规律。通过单因素实验研究表明,在一定范围内电解脱硫率随着煤粒度、电流密度、电解时间、煤浆浓度、电解温度、电解质浓度的变化而呈现规律性变化。Taking raw coal in Tanggongta mine of Ordos Dongchen company as the experimental research object, the influence of electrolysis conditions on total sulfur removal rate was explored by using diaphragmless electrolysis cell under alkaline electrolyte conditions. The single factor experimental study shows that the electrolytic desulfurization rate changes regularly with the change of coal particle size, current density, electrolysis time, coal slurry concentration, electrolysis temperature and electrolyte concentration in a certain range.
