Abstract

The invention discloses a liquid-liquid mixing device and a mixing method. The liquid-liquid mixing device comprises oil-water micro-channel mixing equipment, water-oil micro-channel mixing equipment and a material homogenizer; a lipophilic liquid-phase raw material and a hydrophilic liquid-phase material are mixed through oil-water microchannel mixing equipment according to the proportion being larger than or equal to 1 to form an oil-water mixed material, and the lipophilic liquid-phase material and the hydrophilic liquid-phase material are mixed through water-oil microchannel mixing equipment according to the proportion being smaller than or equal to 1 to form a water-oil mixed material; and the oil-water mixture and the water-oil mixture are homogenized by a material homogenizer and then are used as liquid-liquid reaction feedstock. The liquid-liquid mixing device provided by the invention strengthens the mixing and dispersion between liquid drops from the microscopic level, so that liquid-phase reactants form uniformly-mixed, uniformly-dispersed and stable-mixed-state feeding materials, improves the mixed dispersion state of immiscible or difficult interphase solutions, and is suitable for the liquid-liquid two-phase or multi-phase mixed reaction process.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and in particular relates to a liquid-liquid mixing device and a mixing method in oil refining and chemical process. Background technique [0002] In many liquid-phase reaction processes, the mixing state between the liquid phases participating in the reaction often determines the effect of the reaction, especially involving partially miscible or completely immiscible liquid phases with poor compatibility. One of the phases needs to pass through the phase interface and enter another liquid phase to react. The mass transfer between the liquid phase and the liquid phase becomes the control step of the reaction process. Therefore, it is necessary to mix the liquid phase materials participating in the reaction to form a uniform mixture. One phase is evenly distributed in the other liquid phase in the form of micro-droplets to form a large phase interface, so that a higher reaction rate...
