摘　　要：针对湿式氧化法脱硫过程脱硫液中固含量大,不易处理的特点,采用无机陶瓷膜分离技术对脱硫液中固液分离进行了探索性的研究。实验结果表明,无机陶瓷膜分离过程中,当膜面流速为2.3 m/s,压力控制在0.22 MPa时,脱硫液中固体颗粒的分离效率在93%以上,分离结束脱硫液中固体颗粒最大粒径为5.3μm,固体颗粒数目明显减少。During wet oxidation desulfurization,the larger solid contents in desulfurized solution are hard to handle.To solve this problem,an inorganic ceramic membrane separation technology is used to facilitate the solid-liquid separation for desulfurized solution.The results show that the separation efficiency can reach above 93％ during the polar ceramic membrane separation under the following condition：2.3 m/s of liquid flow rate of the desulfurization solution and 0.22 MPa of pressure control.The maximum particle size in the desulfurized solution after separation is 5.3 μm and the amount of solid particles can be obviously reduced.
