Abstract

The invention discloses a multi-layer rotating disc thin-layer type chemical reactor and a using method thereof. The chemical reactor comprises a shell; an outer fixed disc is fixedly arranged in theshell; at least one discharge hole is formed, a rotating shaft is arranged in the center of an inner cavity of the outer fixed disc, a plurality of layers of inner rotating discs are fixed on the rotating shaft, the inner rotating discs are gap type cavities which are consistent with the inner rotating discs and the rotating shaft in shape, and the outer fixed disc inner cavity and the inner rotating discs are used for mixing materials of all phases and have narrow gaps; the upper surface and the lower surface of the inner rotating disc are both inclined faces inclining outwards from the rotating shaft. The inner rotating disc and the outer fixed disc are matched to form a narrow zigzag cavity to form a Z-shaped or S-shaped mixing chamber, so that the reaction surface area is increased, the reaction time is prolonged, the mass transfer rate is increased, and the reaction rate is increased; according to the invention, two operation modes of forward flow and reverse flow can be realized,especially under the condition of large specific gravity difference, the reverse flow operation can be realized, and the separation or reaction efficiency is improved.

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...
