摘要： The invention provides a device for enhancing liquid-liquid emulsification. The device includes a jet part and a mixing part connected to the jet part. The jet part includes a feed tee for feeding major and dispersed phases, wherein the feed tee includes a first port, a second port, and a third port. The first port is used for feeding the major phase, and the second port is equipped with an ejector for feeding the dispersed phase. The ejector consists of an ejector housing and an ejector inlet section, as well as a spiral structure, a flow-guided structure, and an ejector pin structure that are connected sequentially. The mixing part includes a mixer comprising a cylindrical mixer shell, a mixer inlet section, a mixer outlet section, as well as a spiral section, a cavity section, and a variable diameter section for enhancing emulsion breakup and dispersion. A method for enhancing liquid-liquid emulsification is also disclosed. The emulsion produced by the device and method of the invention is uniformly dispersed, has long stability, and the device has a compact structure and low energy consumption. It is particularly suitable for liquid-liquid emulsification processes in fields such as chemical industry, food, coatings, and cosmetics.
