Abstract

The invention discloses a multi-layer rotating disc thin-layer chemical reactor and a method for using the same. The chemical reactor includes a shell, an outer fixed plate is fixed inside the shell, and at least one discharge port is provided. The center of the inner cavity of the fixed plate is provided with a rotating shaft, and several layers of inner turntables are fixed on the rotating shaft. There are gap-shaped cavities with narrow gaps for mixing the materials of each phase; the upper and lower surfaces of the inner turntable are slopes inclined from the rotation axis to the outside. The present invention increases the reaction surface area and prolongs the reaction time by coordinating the inner rotating disk and the outer fixed disk to form a narrow zigzag cavity to form a Z or S-shaped mixing chamber, thereby enhancing the mass transfer rate and increasing the reaction rate; the present invention can also Realize both forward and countercurrent operation modes, especially in the case of large specific gravity difference, countercurrent operation can be realized to improve separation or reaction efficiency.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and in particular relates to a multi-layer rotating disk thin-layer chemical reactor and a use method thereof. Background technique [0002] The uniform mixing of two immiscible phases has always been a difficult industrial process in the industrial production of chemical, biological, petroleum, metallurgical and other industries. The vast majority of chemical reactions and separation processes involve single-phase or multi-phase mass transfer processes, such as gas-liquid reactions such as distillation, gas stripping, aeration, and gas elution. The oil-water two-phase used for solvent extraction of metal ions is also multi-phase. phase process. In these reactions and processes, only by ensuring a high mixing intensity can they be dispersed into small droplets that are separated from each other, and a high interface volume ratio can be achieved, so that the reaction or separation proc...
