A high-energy-efficiency dispersion-mixing method for large phase systems and its application

Abstract

The invention provides a high-energy-efficiency dispersing-mixing method and its application for a large phase system. The method comprises: passing the continuous phase fluid through a falling film mixing unit to form a film flow; forming the dispersed phase fluid through a high-gravity dispersion unit micro-nano-scale liquid droplets, and mixing the liquid droplets with the continuous phase fluid of film-like flow. In the present invention, by setting the supergravity dispersing unit, the dispersed phase fluid is first dispersed into micro-nano scale liquid droplets, and the falling film mixing unit makes the continuous phase fluid form a flowing liquid film, and then the liquid droplets collide with the liquid film through the supergravity dispersing unit Compared with the traditional mixing method that uses small droplets to mix and stir at the same time, the dispersed phase fluid of the present application is fully dispersed before mixing, and then mixed with the continuous phase, which increases the disturbance of the two-phase mixing interface and improves the mixing efficiency. The degree of dispersion is high, and the falling film unit further breaks up the droplets that disperse and hit the liquid film, improving the utilization rate of energy.

Description

technical field [0001] The invention relates to the technical field of reactors, and more specifically, to a high-energy-efficiency dispersion-mixing method for large phase systems and its application. Background technique [0002] The dispersion mixing process refers to the process of distributing a certain component (dispersed phase) to another component (continuous phase) after being fully refined. The dispersion and mixing effect can be measured according to the size of the dispersed phase droplet size. For a certain volume of dispersed phase, the smaller the droplet size, the larger the interphase mass transfer surface area, and the better the dispersion and mixing effect. [0003] Dispersion mixing technology is widely used in petroleum, chemical, food, pharmaceutical, dyestuff, metallurgy, sewage treatment and other process industries, and plays an important role in homogenization, emulsification, polymerization and other occasions. However, in these process industri...

[0005] In order to solve the problem that the current dispersion and mixing method cannot achieve high dispersion of the dispersed phase and efficient utilization of energy, the present invention provides a high-energy-efficiency dispersion-mixing method for large-phase systems, a high-gravity reactor and its application. The high gravity dispersing unit and the falling film mixing unit are set up. The high gravity dispersing unit first disperses the dispersed phase fluid into micro-nano scale droplets, and the falling film mixing unit makes the continuous phase fluid form a flowing liquid film, and then through the high gravity dispersing unit. The droplets collide with the liquid film. Compared with the traditional mixing method, which uses small droplets to mix and stir at the same time, the dispersed phase fluid of this application is fully dispersed before mixing, and then mixed with the continuous phase to increase the disturbance of the two-phase mixing interface. , so that the mixing efficiency is improved, the degree of dispersion is high, and the falling film unit further breaks up the droplets that disperse and hit the liquid film, which improves the utilization rate of energy
