Problems solved by technology

Recent experimental studies and CFD simulation studies have found that the two-phase liquid mixture in the annulus of the centrifugal extractor has a water-rich phase region in the lower part and an organic-rich phase region in the upper part, resulting in insufficient mixing of the two-phase liquids. Therefore, it is necessary to Find a way to enhance the mixing of two-phase liquids to improve mass transfer stage efficiency

Abstract

The invention discloses an annular gap-type centrifugal extractor with a vertical mixed baffle and belongs to the field of chemical machinery equipment. On the basis of existing annular gap-type centrifugal extractor structure, the annular gap-type centrifugal extractor is characterized in that at least two vertical mixed baffles are uniformly arranged on the inner wall of the lower section of the shell, wherein the lower ends of the vertical mixed baffles are connected with bottom of the shell while the upper ends are connected with the lower part of a light phase colleting ring. According to the invention, the bigger the drum diameter is, the larger the sizes and amounts of the vertical mixed baffles are. According to the invention, the mixing strength of two-phase liquids in the annular gap is strengthened to effectively improve mass transfer efficiency. The annular gap-type centrifugal extractor is characterized by being simple in structure, low in cost, easy in processing and manufacturing and wide in application range. The application level of existing annular gap-type centrifugal extractors is greatly increased, so as to promote the application of the annular gap-type centrifugal extractors in various industrial fields.
