旋转圆板型陶瓷膜过滤器平衡过滤油水乳浊液特性研究

Study on the Charicteristics of Filtration of Oil/Water Emulsion with a Circular Plate with Ceramic Membrane Filter

采用旋转圆板型陶瓷膜过滤器对5%的O/W(油/水)乳浊液进行了精密平衡过滤。过滤压力为50,100,150kPa和圆板旋转速度为125,250,500r/min时,对过滤速度和过滤量的影响进行了对比分析。结果表明,转速为250r/min,压力为50kPa时,达到过滤平衡的时间最短且运行稳定,过滤速度较高过滤量较大,在此条件下过滤效果较为理想。

The 5% O/W（oil/water） emulsion was accurately filtrated by the circular plate with ceramic membrane filter.When the filter pressure was 50 kPa,100 kPa and 150 kPa and the speed of rotation was 125 r/min,250 r/min and 500 r/min,it could compare and analyse the influnce of filtration speeds and amount of filtration.The result indicated that when the speed of rotation was 250 r/min and filter pressure was 50 kPa,the time of reaching to filtration balance was the shortest and it was stable.The higher the filtration rate was,the larger the amount of filtration was.Therefore,the optimal condition was the speed of rotation 250 r/min and filter pressure 50 kPa for the filtration of 5% O/W（oil/water） emulsion.
